Description

[Detailed explanation of the idea] This proposal relates to the base of drawer shapes and disconnectors.

Generally, the base of a drawer type or disconnector is placed on which the cutter, disconnector body, and operating device are placed, and where force is applied to bring the drawer type or disconnector into contact with and away from the primary disconnection section such as a distribution box. Therefore, considerable mechanical strength is required in the vertical and horizontal directions.

For this reason, the conventional base has a rigid welded structure, which is expensive and requires a lot of time to manufacture.

In view of this point, the present invention eliminates the conventional welding work and provides a base for a drawer shape or disconnector that is constructed mainly by bending.

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

In the figure, reference numeral 1 denotes a base made of a rectangular flat plate, and on this flat part 2, a cutting blade, a cutter main body, and an operating device (none of which are shown) are placed. Reference numerals 3 and 3 denote lower bent portions of the side surfaces formed by bending the entire depth direction of both side surfaces of the flat plate downward at a substantially right angle, and an axle through hole 4 is provided in these portions.

Reference numeral 5 denotes an upwardly bent portion of the front surface formed by bending a part of the front surface of the flat plate upward in a substantially perpendicular direction along a line orthogonal to the depth direction, and the front cover of the cutter or cutter is attached here. A hole 6 is provided. A secondary plug, a frequency meter, etc. can be led out from the unbent portion of the front surface as necessary.

7, 7 are bent in a direction opposite to the side lower bent portions 3, 3 by a cut from the center portion of the flat portion 2 toward the side surface, and are bent in a substantially right angle direction, and are flat along the depth direction. There are two upright parts directly connected to the part 2, each of which is provided with an operating shaft mounting hole 8 for the operating device.

Reference numeral 9 indicates four folded portions provided near the squares of the flat portion 2, which are formed by cuts from the center toward the side surfaces, and have gaps between them and the lower bent portions 3, 3 of the side surfaces. It is bent downward at right angles and has the same height as the downward bending part of the side.
Moreover, it is directly connected to the flat portion 2 along the depth direction.

Each center-folded portion 9 is provided with an axle through-hole 10, and a wheel 11 is loaded into the gap between each center-folded portion 9 and the side lower bent portions 3, 3. An axle 12 passing through a pull-out wheel 11 passes through the through-holes 4 and 10 of the part and is pivotally supported.

Therefore, in the base 1 configured as described above,
After placing and fixing the sheath cutter main body and the operating device on the flat part 2, the operating shaft (not shown) of the operating device is attached to the mounting hole 8 provided in the upright parts 7, 7, and the operating shaft and the above-mentioned shield disconnector body are connected so as to be operable by a lever or the like (not shown).

At the upper front bending part 5, there is a front plate of the sheath cutter (normally, the name plate and operating precautions of the sheath cutter are written on this, and the interlock lever passes through this plate and is placed on the front side. ) is fixed using the mounting hole 6 with a fastener such as a screw, bolt, or nut.

Then, the wheels 11 are respectively loaded into the gaps between the side lower bent portions 3, 3 and the middle bent portions 9, and the axles 12 are inserted through the wheels 11 into the through holes 10.
... are respectively penetrated and fixed, and this completes the placement of the cutter, cutter, and operating device on the base 1, and the drawer shape and cutter are completed.

The drawer shape and cutter obtained in this way are based on base 1.
If a horizontal forward force is applied to the top, it will be placed in the withdrawn position, and if a force in the opposite direction is applied, it will be placed in the closed position.

According to the present invention, welding is not used and the base of the drawer shape or disconnector is constructed mainly by bending, so it is extremely inexpensive. Furthermore, the production time can be shortened, and it is also possible to produce the product using only an NC machine. Moreover, the base has the side surfaces bent downward, a part of the front surface bent upward perpendicularly thereto, and the upright part and the folded part bent in opposite directions. It has great practical effects, such as being able to obtain drawer shapes and bases for disconnectors that have no problems in terms of mechanical strength against horizontal forces.
