Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) This invention relates to an operating lever storage structure for a multi-circuit switch.

(Prior art) Conventionally, in multi-circuit switches installed on the ground for underground power distribution, fixed electrodes of each circuit are installed in the upper part of the box-shaped main body case, and the fixed electrodes are moved up and down to contact and separate from the fixed electrodes. A plurality of opening/closing parts each consisting of an opening/closing lid are provided, and an opening/closing part cover is attached to the front surface of each opening/closing part. A closing/opening operation mechanism section for driving the opening/closing lid for each circuit is provided above the opening/closing section, and an operating shaft protruding from the front side of the opening/closing mechanism is manually operated to open/close the opening/closing lid. It's getting old.

The operating shaft is operated by an operating lever that has a grip portion at its base end and a fitting portion that engages with the operating shaft at its distal end. . and,
The operating lever is stored in a case for each switch when not in use.

(Problem to be solved by the invention) However, since this type of multi-circuit switch is installed on sidewalks, etc., there is a demand for a thin design, and it goes without saying that special measures are required for the arrangement of the operating lever. Providing space would lead to an increase in size, and it was difficult to select a location for this control lever.

The purpose of this invention is to provide an operating lever storage structure for a multi-circuit switch that makes effective use of the space within the switch case and eliminates the need to provide a special storage space for accommodating the operating lever.

Structure of the invention (means for solving the problem) This invention was made to solve the above problem, and this invention has a cable connection room at the bottom, and an opening/closing part and its upper part. An opening/closing door is provided at the front opening of the main case housing a multi-circuit switch in which a loading/unloading operation mechanism section is installed, and the loading/unloading operation mechanism section is manually operated against the inner surface of the opening/closing door corresponding to the cable connection chamber. The gist is that a control lever for operating the machine is removably installed.

(Function) With the configuration described above, the operating lever is removably attached to the inner surface of the opening/closing door that corresponds to the cable connection chamber, so when the opening/closing door is closed, there is no space between the front surface of the cable connection chamber and the opening/closing door. will be stored in. or,
When the opening/closing door is opened, the operating lever is retracted from the front surface of the cable connection chamber at the same time as the opening/closing door, so that it does not interfere with cable connection work or the like.

(Embodiment) An embodiment embodying this invention will be described below with reference to FIGS. 1 to 4.

As shown in FIGS. 1 and 2, on the front surface of the main body case 1 of a multi-circuit switch installed on a sidewalk, etc., there are a plurality of left and right opening/closing doors A, B that close a square opening 2. It is pivotally supported by two hinges 10 so as to be able to open double doors. Drainage ridges 11 are provided protruding from the four peripheries of the opening 2. Further, in the upper panel P inside the main body case 1, there are provided a plurality of opening/closing parts (none of which are shown) each having a fixed electrode of each circuit and an opening/closing cover that moves up and down to approach and separate from the fixed electrode. It is being A window is formed in the panel P corresponding to each opening/closing section, and an opening/closing section cover 3 is attached to cover the window.

Above the opening/closing section, there is provided a closing/opening operation mechanism (not shown) for manually or automatically driving the opening/closing lid for each circuit. A rod-shaped operating shaft 4 for driving is provided protruding from the panel P.
The operating shaft 4 can be operated by providing a square annular grip portion 5 at the base end, and a grip section 5 at the distal end.
This is done by an operating lever 7 having a cylindrical fitting part 6 that fits into the cylindrical fitting part 6.

As shown in FIGS. 1 and 3, a cable connection chamber 8 in which a cable L for underground power distribution is arranged is provided below the opening/closing section, and the right end of the cable connection chamber 8 is A control box 9 is provided for automatically closing and opening each of the closing and opening operation mechanisms.

Further, as shown in FIG. 3, reinforcing frames 14 facing into the opening 2 are fixed by welding to the upper, lower, left, right, and center portions of the inner surface of the right door B.
Right opening/closing door B corresponding to the cable connection room 8
As shown in FIG. 4, a base end 16 of an operating lever holding member 15 is fixed to the lower left side of the inner surface of the lever holding member 15, which is formed by bending both ends of a plate material in opposite directions.
The holding member 15 has its base end 16 fixed to the lower left side of the inner surface of the opening/closing door B so that its distal end 17 faces upward and its upper surface slopes downward to the right.

On the other hand, a lower operating lever holding member 18 formed in the same shape as the holding member 15 is fixed to the inner surface of the reinforcing frame 14 on the lower right side of the operating lever holding member 15. Note that, like the upper holding member 15, the lower holding member 18 has a distal end portion 17.
Its base end 16 is fixed to the inner surface of the reinforcing frame 14 so that it faces upward and its upper surface slopes down to the right.

A square annular grip portion 5 of the operating lever 7 is inserted and placed in the upper holding member 15 . Further, the center portion of the operating lever 7 is placed on the upper surface of the lower holding member 18. As shown in FIG. 3, when the opening/closing door B is closed, the operating lever 7 is
5 and 18 in an inclined state, and is arranged to be housed in the front part of the cable connection chamber 8.

The operation of the operating lever storage structure for a multi-circuit switch configured as described above will be explained.

In the operating lever 7 of this multi-circuit switch,
The upper surface of the upper holding member 15 and the lower holding member 1
8 and is housed in the cable connection chamber 8, so when the opening/closing doors A and B are opened, it is pulled out of the cable connection chamber 8. Therefore, the operator can perform cable connection work without being obstructed by the operating lever 7.

Further, when the opening/closing portion is manually operated by the operating lever 7 to drive the opening/closing lid to close and open, the operating lever 7 is removed upward from both the holding members 15 and 18. After the fitting part 6 is fitted to the operating shaft 4 and the operation of the opening/closing part is completed, the square annular grip part 5 of the operating lever 7 is again inserted into the upper holding member 15 and placed. Furthermore, if the center portion of the operating lever 7 is placed on the upper surface of the lower holding member 18, the operating lever 7 can be held on both the holding members 15 and 18. Note that both the holding members 15,
Since the tip 17 of the holding member 18 is bent upward, the operating lever 7 will not fall off from the holding members 15 and 18.

Therefore, when the opening/closing doors A and B are closed, the operating lever 7 is housed in correspondence with the front part of the cable connection chamber 8.

It should be noted that this invention is not limited to the above-mentioned embodiments, and can be arbitrarily modified without departing from the spirit of this invention.

Effects of the invention As detailed above, in this invention, the operating lever is attached to the inner surface of the opening/closing door, so the operating lever does not interfere with the cable connection work when the opening/closing door is opened. Additionally, since the operating lever is stored using the space between the front of the cable connection room and the opening/closing door, there is no need to provide a special storage space for the multi-circuit switch to accommodate the operating lever. It has a great effect.
