Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A wiring device for a rail vehicle power distribution box includes a power distribution box body 1, a wiring frame 2 is provided in the inner cavity of the power distribution box body 1, a support bar 3 is fixedly connected to the inner cavity of the wiring frame 2, a wire fixing assembly 4 is provided on the front side of the support bar 3, and an adjustment assembly 5 that works with the wire fixing assembly 4 is sleeved on the surface of the support bar 3.

[0029] The wire fixing assembly 4 includes a fixing shell 401. Springs 402 are fixedly connected to both sides of the inner wall of the fixing shell 401. Limiting rings 403 are fixedly connected to the opposite side of the two springs 402. A limiting rod 404 is fixedly connected to the left side of the inner wall of the fixing shell 401. The right side of the limiting rod 404 passes through the springs 402 and the limiting rings 403 in sequence and is fixedly connected to the right side of the inner wall of the fixing shell 401. The inner walls of the springs 402 and the limiting rings 403 are slidably connected to the surface of the limiting rod 404. A connecting block 405 is fixedly connected to the front side of the limiting rings 403. The front side of the connecting block 405 passes through to the outside of the fixing shell 401 and is fixedly connected to an arc-shaped locking block 406.

[0030] In this embodiment: by setting up a distribution box 1, a wiring rack 2, a support bar 3, a wire fixing assembly 4, and an adjustment assembly 5, in use, the wiring rack 2 is fixedly installed in a suitable position inside the distribution box 1. The support bar 3 can support the wire fixing assembly 4 and the adjustment assembly 5. The wire fixing assembly 4 can fix the wires inside the distribution box 1 in a convenient way, which facilitates the disassembly and maintenance of the wires later, bringing convenience to the staff. The adjustment assembly 5 can adjust the position of the wire fixing assembly 4 according to the wiring requirements, and the wire fixing assembly 4 can be rotated to adjust the wire fixing angle, thereby improving the flexibility of the wiring.

[0031] Specifically, such as Figure 2 , Figure 3 , Figure 5As shown, the adjustment component 5 includes a sliding sleeve 501, which is sleeved on the surface of the support bar 3. The inner wall of the sliding sleeve 501 is slidably connected to the surface of the support bar 3. A torsion ring 502 is provided on the top of the front side of the sliding sleeve 501. A fixing screw 503 is fixedly connected to the rear side of the torsion ring 502. The rear side of the fixing screw 503 passes through the sliding sleeve 501 and extends into the inner cavity of the support bar 3.

[0032] Specifically, such as Figure 2 , Figure 3 , Figure 5 As shown, a rotating self-locking ring 504 is fixedly connected to the bottom of the front side of the sliding sleeve 501, and the front side of the rotating self-locking ring 504 is fixedly connected to the rear side of the fixed shell 401.

[0033] Specifically, such as Figure 5 As shown, the top of the front side of the sliding sleeve 501 is provided with a threaded hole 6 that is used to cooperate with the fixing screw 503, and the front side of the support bar 3 is provided with a threaded groove 7 that is used to cooperate with the fixing screw 503. The surface of the fixing screw 503 is connected to the inner wall of the threaded hole 6 and the threaded groove 7 by threads on the side close to the inner wall of the threaded hole 6 and the threaded groove 7 respectively. There are several threaded grooves 7, which are evenly opened on the front side of the support bar 3.

[0034] In this embodiment: by providing a sliding sleeve 501, a torsion ring 502, a fixing screw 503, a rotating self-locking ring 504, a threaded hole 6, and a threaded groove 7, in use, by moving the sliding sleeve 501, the sliding sleeve 501 slides on the surface of the support bar 3. The sliding sleeve 501 drives the rotating self-locking ring 504 to move, and the rotating self-locking ring 504 drives the fixing shell 401 to move. After moving to a suitable position, by rotating the torsion ring 502, the torsion ring 502 drives the fixing screw 503 to rotate. The fixing screw 503 moves under the action of the threaded hole 6. The fixing screw 503 is moved into the inner cavity of the threaded groove 7 to fix the position of the sliding sleeve 501, thereby achieving the effect of adjusting the position of the wire fixing assembly 4 according to the wiring requirements. Then, by rotating the self-locking ring 504, the self-locking ring 504 will drive the fixing shell 401 to rotate. After rotating to a suitable angle, the locking function of the self-locking ring 504 can lock the position of the fixing shell 401, thereby achieving the effect of adjusting the fixing angle of the wire fixing assembly 4 according to the wiring requirements, improving the wiring flexibility.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, a limiting groove 8 is provided on the front side of the fixed shell 401 to cooperate with the connecting block 405. The side of the connecting block 405 near the inner wall of the limiting groove 8 is slidably connected to the inner wall of the limiting groove 8.

[0036] Specifically, such as Figure 3 , Figure 4As shown, an elastic pad 9 is fixedly connected to the inner side of the arc-shaped card block 406. The elastic pad 9 is made of rubber.

[0037] In this embodiment: by setting the limiting groove 8, the connecting block 405 can be limited so that the connecting block 405 will not shake and can move left and right easily. By setting the elastic pad 9, the arc-shaped locking block 406 can be prevented from scratching the surface of the wire and the friction can be increased, thereby improving the fixing effect of the wire.

[0038] Specifically, such as Figure 2 As shown, there are several support bars 3, which are evenly distributed in the inner cavity of the wiring frame 2. There are several mounting holes 10 on both sides of the front side of the wiring frame 2.

[0039] Specifically, such as Figure 2 As shown, the top and bottom of the front side of the wiring rack 2 are fixedly connected with winding discs 11. There are several winding discs 11, which are evenly distributed on the top and bottom of the front side of the wiring rack 2.

[0040] In this embodiment: by setting multiple support bars 3, multiple lines can be arranged; by setting mounting holes 10, the wiring rack 2 can be easily installed and fixed to the distribution box 1; by setting a winding reel 11, excessively long wires can be wound and stored on the winding reel 11.

[0041] Working Principle: In use, the wiring bracket 2 is fixedly installed in a suitable position inside the distribution box 1 according to the actual situation. When fixing the wire, by pulling the two arc-shaped clamps 406, the two arc-shaped clamps 406 move in opposite directions. When the arc-shaped clamps 406 move, they will drive the limiting ring 403 to slide on the surface of the limiting rod 404 through the connecting block 405. The limiting ring 403 will compress the spring 402. Then, the wire is placed between the two arc-shaped clamps 406 and the arc-shaped clamps 406 are released. At this time, the force released after the spring 402 is compressed will drive the limiting ring 403 to slide in the opposite direction on the surface of the limiting rod 404. The limiting ring 403 drives the arc-shaped clamps 406 to move in the opposite direction through the connecting block 405. The two arc-shaped clamps 406 moving in opposite directions can clamp and fix the wire. The operation is relatively convenient, which facilitates the disassembly and maintenance of the wire later. The movable sleeve 501 allows the sliding sleeve 501 to slide on the surface of the support bar 3. The sliding sleeve 501 drives the rotating self-locking ring 504 to move, which in turn drives the fixed shell 401 to move. After moving to the appropriate position, the torsion ring 502 is rotated, causing the torsion ring 502 to drive the fixed screw 503 to rotate. The fixed screw 503 moves under the action of the threaded hole 6, moving into the inner cavity of the threaded groove 7 to fix the position of the sliding sleeve 501. This allows the position of the wire fixing assembly 4 to be adjusted according to the wiring requirements. Then, by rotating the rotating self-locking ring 504, the rotating self-locking ring 504 drives the fixed shell 401 to rotate. After rotating to the appropriate angle, the locking function of the rotating self-locking ring 504 can lock the position of the fixed shell 401. This allows the wire fixing angle of the wire fixing assembly 4 to be adjusted according to the wiring requirements, improving the wiring flexibility.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
