The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-2, a wire fixing device for an electrical power distribution cabinet includes a first movable splint 1, one side of the first movable splint 1 is equidistantly provided with a plurality of first wire clamping slots 2, and the first movable splint 1 A plurality of second movable clamping plates 3 are arranged on the same side of the first wire clamping groove 2, and the number of the second movable clamping plates 3 is the same as that of the first wire clamping grooves 2 and the positions are in one-to-one correspondence, and the second movable clamping plates 3 are opposite to each other. One side of the first movable splint 1 is provided with a second wire clamping slot 4, an elastic sliding device is provided between every two adjacent second movable splints 3, and the two second movable splints 3 on the most side are connected with the first movable splint 3. A distance adjusting device is arranged between the movable splints 1;

The elastic sliding device includes a slider 10 fixed on one of the second movable splints 3 and a chute 11 opened on one side of the other second movable splint 3, and the slider 10 is slidably connected with the chute 11. The inner walls on both sides are fixedly connected with a fixed rod 12, the slider 10 is slidably sleeved on the fixed rod 12, and a spring 13 is movably sleeved on the fixed rod 12, and the spring 13 and the slider 10 are away from the side of the first movable splint 1, The inner walls of the chute 11 are against each other;

The distance adjusting device includes a first nut 5 and a second nut 6 which are symmetrically arranged and fixed on the first movable splint 1 and the second movable splint 3 respectively. The first nut 5 and the second nut 6 are respectively screwed with a first screw. 7 and the second screw 16, and the first screw 7 and the second screw 16 have the same length and diameter, the thread rotation direction is opposite, the thread rotation direction of the first nut 5 and the second nut 6 are the same, the first screw 7 and the second screw 16 A rotating block 8 is fixedly connected to the opposite end.

The first wire clamping slot 2 and the second wire clamping slot 4 have the same structure and are arc-shaped, and are suitable for conducting wires with a circular cross-section.

The opposite ends of the first screw 7 and the second screw 16 are fixedly connected to the limiting plate 9 to limit the movable range of the first nut 5 and the second nut 6 to avoid separation.

The sliding block 10 is in the shape of a dovetail, and the sliding groove 11 is a dovetail groove, which restricts the sliding block 10 from sliding in the sliding groove 11, and the movement of the second movable splint 3 is more stable.

An arc-shaped handle 14 is fixedly connected to one side of the plurality of second movable splints 3 located in the middle portion away from the first movable splint 1 , so that the second movable splint 3 can be easily pulled.

A label frame 15 is fixedly connected to one side of the plurality of second movable splints 3 away from the first movable splint 1 , and the label frame 15 is made of transparent plastic, which is convenient to see more intuitively.

Before using the device, firstly install the first movable splint 1 and the two second movable splints 3 on the farthest side in the power distribution cabinet in a radial sliding manner. A slide rail is installed at the bottom of the second movable splint 3, and the slide rail is fixedly installed in the power distribution cabinet. The relative position of the wire fixing device in the power distribution cabinet can be adjusted, and multiple wires can be installed on the slide rail. Fixtures are suitable for scenarios with a large number of wires.

When using this device, a plurality of wires are inserted between the first wire clamping slot 2 and the second wire clamping slot 4 corresponding to the positions, and the rotating blocks 8 in the two distance adjusting devices are rotated at the same time to drive the first screw rod 7 and the second wire clamping groove 4.
