Description

[Detailed Description of the Invention] The present invention relates to an outlet box for supplying electricity to vibrators and many other electrical devices at concrete casting sites and the like.

When using vibrators and many other low-voltage electrical devices at concrete pouring sites,
An outlet box is used as a power distribution tool with many outlets attached.

When such an outlet box is in use, a large amount of cement paste tends to enter the outlet, resulting in poor contact between the outlet and the plug. The disadvantages of this are that the protective function to protect against concrete splashes is incomplete, that if the box itself falls over, cement paste can easily enter the box, and that when the cord of a vibrator or other device is being passed around, the plug may come off from the outlet, causing the cement paste to enter the box. This is thought to be caused by plugging the plug back into the outlet with the paste still attached.

The object of the present invention is to provide an outlet box that completely protects the outlet from such concrete splashes, makes the outlet box itself difficult to fall over, and prevents the plug from falling off.

Further, the present invention provides an outlet box having a structure that improves workability in inspecting and repairing the outlet box, and enables rationalization of manufacturing and assembly work.

The present invention will be explained below based on an embodiment shown in the drawings.

FIG. 1 is an overall perspective view of an embodiment of the outlet box, in which an L-shaped plate 4 with a large number of outlets attached is placed inside a box-shaped case 1 with the front side 2 open and the front end of the bottom plate 3 bent into a sled shape. and is fixed to the bottom plate 3.

FIG. 2 is a sectional view of the outlet box.
A large number of outlets 11 are attached to the L-shaped plate 4.

The L-shaped plate 4 is housed in the case 1 with its top part fixed to the center of the top plate 5 and its bottom part fixed to the front end of the bottom plate 3, with the L-shaped plate 4 tilted forward.

Each outlet 11 is connected to a power source via a power socket 17 and a terminal board 18.

FIG. 3 is a front view of the L-shaped plate 4. Although the outlet sockets 11 are shown arranged in two stages, upper and lower, the present invention is not limited thereto. The figure shows the state immediately before the upper protection plate 7 is rotated upward and the plug is inserted into the outlet. Although one protective plate 7 is shown for each of the upper and lower tiers, it is of course possible to divide the protective plate 7 as appropriate.

Reference numeral 10 denotes a hole for attaching the L-shaped plate 4 to the case 1, which may be a screw hole or a hole secured with a nut, if necessary. Case 1 and L-shaped plate 4
It is detachably attached using screws, bolts 6, etc. shown in FIG. 2, for example, and can be easily manufactured and assembled, and can be easily disassembled and assembled for repair. This attachment method is, of course, not limited to bolts, etc., and may be any other method of fixing, such as hinges, latches, pivots, etc., which can be disassembled.

In addition, 15 is a live line indicator light.

A protection plate 7 is suspended from the front surface of the outlet of the L-shaped plate 4. (Figures 2 and 3).

The protective plate 7 prevents cement paste or rainwater from splashing on the outlet, and its upper end is
It is hinged to a bracket 8 provided on the template, and is suspended so as to be able to rotate around the pin of this hinge part. 7a shown in FIG. 2 shows a state in which it is rotated upward.

A hook piece 9 is provided on the back side of the protection plate 7 at a portion facing each outlet. FIG. 4 is a partial sectional view showing a state in which a plug is attached to the outlet box of the present invention. The hook piece 9 is an L-shaped protruding body for hooking provided on the back surface of the protection plate 7, and is provided so as to hook an annular hook 14 attached to the neck of the plug 12. There is. The hooking piece 9 may be separate from the protection plate 7 and fixed to the protection plate 7 by welding or the like, or it may be made by cutting a part of the protection plate 7 as illustrated in FIG. It may also be made to protrude. FIG. 6 shows the annular catch 14 of the plug 12.
This is an example showing a state in which a hook 9 is engaged with a hook 9 protruding from a protection plate 7.

As is clear from Fig. 4, since the L-shaped plate 4 on which the outlet 11 is attached is tilted forward, the plug 1
When the cord 13 is inserted, the cord 13 naturally hangs down and reaches the floor.

Since the outlet box of the present invention has a box-shaped case, there is little risk of it falling over.

The connecting part between the outlet 11 and the plug 12 is housed in a box-shaped case 1, and since the top plate 5 is shaped like an eaves, it is protected from rainwater and scattered concrete paste. In addition, the L-shaped plate 4 to which the outlet 11 is attached is attached in a forward-leaning position, and the protective plate 7 that covers the outlet 11 is suspended from the front, so that rainwater and
More secure against flying concrete paste intrusion.

When the plug 12 is connected to the outlet 11, the protective plate 7 is in the state 7a as shown in FIG. 2, and acts as an eaves. The plug 12 and cord 13 are inserted into the outlet 11 from diagonally downward to diagonally upward.
, so there is no risk of rainwater running down these surfaces and entering the outlet.

In addition, since the cord 13 naturally hangs down from the obliquely upwardly oriented plug 12 and comes into contact with the floor surface, the disadvantage that the plug is easily pulled out due to the cord's own weight is eliminated compared to the conventional method in which the plug is inserted horizontally. .

A claw 9 is formed on the back surface of the protection plate 7, and this hook piece 9
Furthermore, since the hook 14 attached to the socket 12 is locked, there is no fear that the plug 12 will come off when the cord is pulled.

Therefore, it is possible to avoid poor contact and other troubles due to loosening or disconnection of the plug, and it is also possible to prevent contamination of the outlet due to re-insertion of a plug that has become contaminated due to disconnection.

The product of this invention has a simple structure consisting of a box-shaped case made of two bent metal plates combined with an L-shaped plate with an outlet attached, which simplifies the manufacturing process and allows for inspection. Repairs are also easy.

Furthermore, when using the device on rough terrain and shifting its position forward, the sled-shaped portion at the front end of the bottom plate can move without getting caught on uneven terrain, and there is little risk of it falling over.

As detailed above, the product of the present invention is a power outlet box that is completely protected from cement paste and rainwater, is easy to handle, safe, lightweight, and inexpensive, and is an excellent choice for use at concrete pouring construction sites. It is effective.
