Description

[Detailed description of the invention] <Industrial field of application> This invention relates to a coupling device that allows equipment such as controllers to be attached to a steel pipe column for traffic signals to be movable within a certain range depending on road conditions. be.

<Problems to be solved by conventional techniques and ideas> Currently, when installing a traffic signal controller on a signal steel pipe column, for example, as shown in Fig. 9, from inside the signal steel pipe column a to the controller b, A flexible tube c that can withstand external shocks is installed, and a cable is connected to the controller b from the cable outlet d of the signal-only steel pipe column a through the flexible tube c. However, if the direction of the controller b is to be swung toward the road or sidewalk depending on road conditions, even if the controller b itself can be freely attached using a flexible band, the cable of the steel pipe column a for signal use may Since the outlet d cannot be changed, the controller b and the cable outlet d are misaligned, which is unfavorable in terms of appearance, and it is currently impossible to install the cable in a misaligned state.

In order to solve the above-mentioned problems, the purpose of this invention is to provide a connector between the cable outlet of the signal steel pipe column and the equipment that can be freely swung from side to side within a certain angle. That is.

<Means for Solving the Problems> The above objects of the present invention can be achieved by a coupling mechanism having the following configuration. In other words, the gist is that the connector fixing part is provided in an arcuate shape above and below the cable outlet inserted through the traffic signal steel pipe column, and the connector fixing part and the cable outlet are covered. , the base end opening line is shaped so as to be in close contact with the outer circumferential wall of the steel pipe column for traffic signals, and the coupling device has a cable insertion port penetrating through the outer circumferential wall at the distal end thereof, An arc-shaped elongated hole and a bolt insertion hole are provided in the upper and lower parts of each of the above-mentioned connector fixing parts, respectively, and the above-mentioned elongated hole and the bolt insertion hole are connected to the above-mentioned elongated hole and the bolt insertion hole by fastening parts such as bolts and nuts. This is a movable connection mechanism for equipment and equipment in a steel pipe column exclusively used for traffic signals, characterized by the fact that the connectors can be connected so as to be rotatable left and right.

<Embodiments and Effects> The movable coupling mechanism for equipment and equipment in the steel pipe column for traffic signals according to the present invention will be described in detail below with reference to the drawings showing the embodiments thereof.

FIGS. 1A and 1B are explanatory views of a steel pipe column exclusively used for traffic signals according to the present invention, and FIG. 2 is a perspective view showing an embodiment of the connector A according to the present invention.

That is, arc-shaped connector fixing parts 3, 3 are provided in a brim-like manner at the top and bottom of the cable outlet 2 opened in the outer peripheral wall of the traffic signal steel pipe column 1.
Further, arc-shaped elongated holes 4, 4 are provided through the connector fixing parts 3, 3, respectively. Next, the connector A in FIG. 2 is a box whose proximal end side is opened so as to cover the cable outlet 2 and the connector fixing parts 3, 3, and the proximal opening line 5. is formed in an arcuate shape so as to be in close contact with the outer peripheral wall of the steel pipe column 1 exclusively for traffic signals. Bolt insertion holes 6, 6 are provided in the upper and lower walls of the connector A.
The bolt insertion holes 6, 6 are provided at the same position as the elongated holes 4, 4, which are penetrated through the connector fixing parts 3, 3, and When moving from side to side, the long holes 4,
4 and the bolt insertion holes 6, 6 are provided at the same position.

Therefore, when connecting and fixing the connector A and the connector fixing parts 3, 3, as shown in FIG.
and the nut 1 screwed into the same bolts 10, 10.
As shown in FIG. 4, the bolts 10, 10 are inserted into the elongated hole 4 and the bolt insertion holes 6, 6 from inside the connecting tool A, and then A cable insertion port 7 is opened on the outer circumferential wall of the distal end of the tool A, and connection holes 8, 8, . . . are provided around the cable insertion port 7.

It is connected and fixed by the nuts 11, 11, and has a mechanism that allows the direction to be adjusted freely by loosening the nuts 11, 11 when the connector A is to be swung left and right. It is.

The present invention having the above configuration is used when attaching various equipment and equipment. For example, as shown in FIG. 5, when installing the controller B, a duct C is attached to the bottom of the controller B, and the base end of the duct C is connected to the connector A in a continuous manner. In this case, they may be connected by bolts and nuts, but it is also possible to form the duct C and the connector A integrally as shown in FIG.

Furthermore, as shown in FIG. 7A and B, there is a mechanism for directly connecting and fixing the outdoor instrument box D and the telephone line box E to the connector A.

Furthermore, as shown in Fig. 8, when installing the pedestrian light F, the frame pipe G is connected and fixed to the coupling A, and the pedestrian light F is suspended from the frame pipe G. It is.

<Effects of the invention> As described above, according to the invention, by attaching equipment such as a controller via a connector that can be moved left and right, its direction can be changed to the road side or to the road side depending on the road condition. Or, if it becomes necessary to swing the cable towards the pedestrian, the direction can be easily changed by loosening the fastening part, and by forming the cable outlet in advance into a left and right elliptical shape, The direction can be freely changed without causing problems such as misalignment.
