Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improved lockable lidded channel block capable of housing and protecting communication and power distribution cables.

BACKGROUND ART Conventionally, overhead wiring has been the main type of communication and power distribution lines, and underground lines using common ditches have been used to the bare minimum. In addition, electrical lines on the ground surface (for example, cable troughs listed in the Concrete Products Handbook published by the Cement Association of Japan) were found to be installed within the premises of factories and railways, but since they were located within the premises, no consideration was given to locking devices.

However, undergrounding has become a problem because overhead wiring obstructs disaster prevention activities and pollutes the cityscape. In addition, with the arrival of the New Media era, urban
While the number of communication lines, including CATV, is expected to increase, the problem has become even more serious because underground wiring paths require equipment costs that are several to ten times higher than overhead wiring paths. Therefore, in order to reduce equipment costs, there has been a demand for laying electric lines as close to the ground surface as possible and for a structure that safely protects the lines. As a specific example, mini-community ditches (for example, the mini-community ditch structure diagram described on page 7 of the foreword of the May 1984 issue of the cost estimate material) were installed on a trial basis, but there was a problem in that the cover could not be removed as necessary. .

Problems that the invention aimed to solve: In order to easily pull out and pull in electric wires as needed, the lid must be easy to attach and remove, and the lid cannot be removed by anyone other than the administrator. There is a need for a structure that has the contradictory properties of being protected from being easily damaged by damage.

Means for Solving the Problems The present invention protects the electric line with a concrete block, provides a fitting groove in the upper part of the side wall of the groove block, and provides a cover block with a side surface shape that fits into this groove. When assembled, it becomes a box-shaped block, and when necessary, the contents such as electric wires can be easily taken out by pulling the lid block sideways and opening or removing the lid. In addition, key points are equipped with locks made of screws, etc., to prevent anyone other than the administrator from opening the lid.

Therefore, even the least expensive electric line, with its cover exposed above the ground, is safely protected.

Function The present invention is a groove block with a lid, which has the function of fixing the lid of the groove block by the above-described means when it is locked, and easily opening the lid when the lock is released.

Embodiments Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a perspective view of a first embodiment of the present invention. FIG. 1 shows a lid block 2 with engaging protrusions 5 at both ends thereof. Figure 1 2
1 is a groove block 1 which has a notch 3 in the center in which the engagement protrusion 5 can fit in the upper part of the inner surface of the side wall, and engagement grooves 4 in which the engagement protrusion 5 can be engaged are provided at both ends thereof. Therefore, after installing the groove block 1, lower the lid block 2 so that the engagement protrusion 5 fits into the notch 3 of the groove block 1, and move the groove block 1 so that the engagement groove 4 and the engagement protrusion 5 engage with each other. 2
is fixed to the groove block 1. Fig. 1 3 shows a lid block for locking, which is shaped like the engaging protrusion of the lid block 2 and the other parts are divided into three parts.
a locking lid 6 equipped with a locking protrusion 5 and a key screw 8;
This figure shows a locking lid 7 having a keyhole 9. After attaching the cover block 2 to the groove block 1, attach the engagement cover 6, close the locking cover 7, and lock the key such as the key bolt 19 to the key screw 8 through the keyhole 9, then all the cover blocks will be closed. 2 is fixed and cannot be removed or opened by moving sideways, and the stored items can be safely protected.

FIG. 2 relates to a second embodiment of the invention and is shown as a cross-sectional view. This second embodiment is
Only the engagement portions of the groove block 1 and the lid block 2 are each made into a single block, and a locking block is also taken into consideration. FIG. 2 1 shows the block of the engagement part, and shows the state in which the engagement protrusion 15 of the engagement lid block 12 is engaged with the engagement groove 14 of the engagement groove block 11, and FIG. 2 2 is for locking. The locking groove block 16 has a locking groove 14 on one side wall, a cutout 20 on the other side, and a keyhole 9. The locking lid block 17 has a locking projection 15 on one side and a shape overlapping the cutout surface 20 of the groove block on the other side, and is provided with a keyhole 9. As shown in the plan view in FIG. 3, a plurality of engagement groove blocks 11 and locking groove blocks 16 are laid,
Insert the engaging lid block 12 from above, move it sideways and close the lid, and finally put the locking lid block 17 in and lock it with the key bolt 19, etc., and all the lids are fixed.

This embodiment requires a light lid block that is suitable for relatively small-scale railways and is easy to move laterally.
Note that the drawing opening 13 in the drawings is a circular hole that can be easily opened by applying a blow to the drawing, making it easy to draw out the wire. If the periphery of the outlet 13 is lined with a PVC pipe or a steel pipe socket, it will be easy to make a hole and it will be easy to connect the outlet line to the protection pipe and to stop water. Furthermore, if a packing 18 made of a high-performance water pumping material or the like is arranged to stop water at the joint, the water-stopping performance will be improved. Furthermore, as shown in the plan view of FIG. 4 1 and the vertical sectional view of FIG. A mating structure is preferred. This also applies to other embodiments.

FIG. 5 shows a cross-sectional view of the third embodiment. In this embodiment, the opening is oriented horizontally so that it can also serve as a boundary block such as a sidewalk boundary, and FIG.
4' is provided, and the engaging lid block 12' having an engaging protrusion 15' shaped to engage therewith is engaged. FIG. 5 2 shows a locking groove block 16' having a cutout surface 20' on the upper surface of the engagement groove 14' on the lower surface of the opening to facilitate insertion. The locking lid block 17' has a locking protrusion 1.
It is equipped with a 5' keyhole 9 and is shown in a locked state with a key bolt 19. In FIGS. 1, 2, and 4, the shapes of the engagement grooves 4, 14, and 14' are shown as follows.
Although the illustrations have been shown with angular and rounded shapes, this is not because these shapes are suitable for each method of use, but rather that there are various shapes of the engagement groove and engagement protrusion. The purpose is to show. Therefore, the shape is not limited to each embodiment, but can be freely combined. For example, when fitting a large item such as a mini common groove, a metal plate is attached to the fitting surface of the groove block 1, and the fitting protrusion 5 of the lid block 2 is made of a metal plate, and the fitting groove 4 is also shaped to correspond to the fitting protrusion 5. This means making efforts such as improving the quality of the product. For example, the first
FIG. 1 is a perspective view, FIG. 12 is a cross-sectional view, and FIG. 13 is an enlarged cross-sectional view of the engagement part. The engagement groove 4 is formed in the groove block 1 by a metal engagement groove protrusion 25, and is formed by fitting the metal engagement protrusion 5 of the lid block 2 into the notch 3' and then moving it laterally.
It is agreed. Note that if the entire upper surface of the groove block 1 is covered with a metal plate integrated with the metal engagement groove protrusion 25, the sliding will be further improved.

Next, another embodiment of the present invention will be shown.

FIG. 6 shows a cross-sectional view of an application example in which the groove block has two grooves. FIG. Fig. 6 shows the third embodiment with two grooves having different heights.

FIG. 7 shows a groove block of the first embodiment of the present invention, which consists only of locking elements. FIG. 7 1 is a plan view of the groove block 1', and FIG. 7 2 is a side view thereof.
3 and 4 show a plan view and a side view of the engagement lid 6',
FIGS. 5 and 6 show a plan view and a side view of the locking lid 7'. This application is effective when the groove block is long in shape. Further, although the locking is done by using a lid and a groove instead of lids and lids as in the first embodiment, this is not a necessity for this application example, but is illustrated to show the combination and mode of locking. That is, as in the first embodiment, there is a lid and a lid, as in the second and third embodiments, the lid is locked on the top surface of the groove, or as in this application example, the lid is provided on the lid block 7'. Key screw 8'
In addition, there is also a device that is installed in the opposite way to the above embodiment, in which the lock is locked from the keyhole 9' provided on the upper part of the side wall of the groove block 1'.The combinations are not limited to each, and the best combination for use can be selected as appropriate. A locking method may be used.

FIG. 8 is a partially enlarged front view and a sectional view showing one embodiment of the locking part. The lid block 7', in which the key screw 8' made of a nut or socket made of synthetic resin or iron, or a compression screw made of brass, is embedded, is lowered onto the groove block 1', and the keyhole 9' of the groove block 1' is inserted.
From there, insert the key bolt 19 through the washer and attach the key screw 8'.
is screwed in and locked, and the area around the keyhole 9' is filled with an appropriate filler 23. The head of the key bolt 19 is machined into a special shape that can only be operated with a special spanner.

9 and 10 are plan and side views of an application example in which the number of engagement grooves and engagement protrusions is increased in the first embodiment shown in FIG. 1. FIGS. 9 1 and 2 show a groove block 1'' in which a plurality of engagement grooves 14 and notches 3 are continuous and integrated, and FIGS.
The lid block 2'' shown in Fig. 4 is provided with the same number of engagement protrusions 15 as the groove block 1''. Figures 1 and 2 show a groove block 1'' for locking.
It may be the same as the groove block 1'' described above, but in the drawing it is shown as having a key screw 8'.Next, Fig. 10 3 and 4 show a lock block with one convex portion less than that of the cover block 2'. The lid 6'' is shown in Figure 10, 5 and 6.
The locking lid 7' is shown. This locking lid 7' may be the same as the first embodiment, but the only difference is that since a key screw 8' is provided in the locking groove block 1'', a key hole 9' that engages with the key screw 8' is provided. .

Effects of the invention As mentioned above, the present invention combines a groove block with a fitting groove on the inner surface of the side wall and a lid block equipped with a fitting protrusion that fits into the fitting groove, and arranges a locking block at an appropriate location. By locking the cable, it is possible to safely protect the electrical line even if the cover is exposed on the ground surface, and when necessary, the cover can be opened at any location by unlocking and moving the cover. It is useful because it can be opened or removed, making it easy to make changes after installation.

In addition, if a female screw is embedded in the inner side wall, a shelf material is attached, and the wiring is separated according to purpose, it can be used as a common channel for communications, electric power, and CATV. Of course, in such a large groove block, as mentioned above, a metal plate is used for the engagement protrusion of the lid block, the groove block engagement groove, and the contact surface, a jack is used for sliding the lid block, or a metal plate is used for the groove block and the lid block. Consideration shall be given to embedding a female thread for attaching the hanger, or using a key screw or keyhole for attaching the hanger.

In any case, it can be widely applied from single wire cables to common cables for various types of cables, and can be safely protected even when exposed on the ground surface. Therefore, it has the practical benefit of being able to construct a pipeline with a lower equipment cost than ever before.
