[0002] Rail vehicles, as one of the most important means of transportation, play a vital role in people's lives and work. Cables, responsible for transmitting signals and ensuring the normal operation of rail vehicles, are essential for their safe operation. Due to differences in vehicle type, model, and purpose, conventional rail vehicles require a wide variety of junction boxes with numerous interfaces.

[0003] After the existing track cables are installed in the junction box, the cables are placed randomly in the junction box without being arranged or fixed, resulting in a messy arrangement of cables inside the junction box, which can easily affect later maintenance work. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a quick-installation cable distribution box for rail transit. This solves the problem that after existing rail cables are installed in the distribution box, they are placed randomly without being arranged or fixed, resulting in a messy cable arrangement inside the distribution box, which can easily affect subsequent maintenance work.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A movable seat is provided on the side of the fixing seat away from the mounting plate. Two opposing sliding rods are slidably mounted on the movable seat. One end of each sliding rod is connected to the fixing seat, and the other end of each sliding rod has a limiting plate located outside the movable seat. Second connecting plates are symmetrically arranged on both sides of the movable seat. Locking grooves are provided on the second connecting plates for the locking rods to engage after rotation.

[0007] As a preferred embodiment of this utility model, a drive spring is coaxially sleeved on the outer side of the slide rod between the fixed seat and the movable seat.

[0008] The above technical solution utilizes the elastic force generated by the compression of the drive spring, thereby improving the locking effect of the locking rod on the moving seat.

[0009] As a preferred embodiment of this utility model, an assist rod is provided on the outer side of the end of the support rod near the first connecting plate.

[0010] The above technical solution utilizes the auxiliary rod to facilitate the worker's drive of the support rod to rotate and displace the locking rod.

[0011] As a preferred embodiment of this utility model, both the fixed base and the movable base are provided with clamping grooves, and the clamping grooves are provided with clamping plates with an arc-shaped structure. The inner end face of the clamping plate is provided with a plurality of compression springs connected to the inner side wall of the clamping groove.

[0012] The above technical solution utilizes the clamping plate and compression spring to clamp and fix cables of various sizes to a certain extent.

[0013] As a preferred technical solution of this utility model, the upper and lower ends of the distribution box are provided with multiple wiring slots that communicate with its inner cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In use, first connect the cable to the junction box, positioning it between the fixed and movable seats. Press the movable seat to move it towards the fixed seat, thus clamping and securing the cable. Then, drive the support rod via the assist rod to rotate the locking rod, causing it to engage with the locking groove in the second connecting plate. Finally, loosen the movable seat to lock the locking rod in the locking groove, thus limiting and fixing the moved seat and stabilizing the cable's position. This invention allows for the orderly arrangement of cables within the junction box, preventing multiple cables from becoming tangled and improving wiring efficiency. It also provides a secure constraint for cables placed between the fixed and movable seats. Attached Figure Description

[0022] Example

[0023] This utility model provides a quick-install cable distribution box for rail transit, reference. Figure 1-3 As shown, the cable distribution box 1 includes a mounting plate 2 with both ends connected to the inner wall of the cable distribution box 1. Multiple evenly distributed fixing seats 3 are provided on the outer end face of the mounting plate 2. First connecting plates 5 are symmetrically and integrally formed on both sides of each fixing seat 3. Support rods 6 are rotatably mounted on both sides of each first connecting plate 5. A locking rod 7 is welded between two support rods 6. A movable seat 4, cooperating with the fixing seat 3 on the side away from the mounting plate 2 to clamp the cable, is provided. Two opposing sliding plates are slidably mounted on the movable seat 4. The slide rod 15 has one end connected to the fixed seat 3 and the other end of the slide rod 15 is provided with a limiting plate 14 located outside the movable seat 4. The limiting plate 14 is provided to prevent the movable seat 4 from detaching from the slide rod 15. The movable seat 4 is provided with second connecting plates 12 symmetrically on both sides. The end face of the second connecting plate 12 away from the first connecting plate 5 is provided with a locking groove 13 for locking rod 7 to be engaged after rotation. The locking groove 13 and the locking rod 7 are provided to fix and constrain the cable placed between the fixed seat 3 and the movable seat 4.

[0024] The junction box 1 has multiple wiring slots that are connected to its internal cavity at both the top and bottom ends.

[0025] Among them, a drive spring 11 is coaxially sleeved on the outside of the slide rod 15 between the fixed seat 3 and the movable seat 4. One end of the drive spring 11 is connected to the fixed seat 3, and the other end of the drive spring 11 is connected to the movable seat 4. The elastic force generated by the compression of the drive spring 11 improves the locking effect of the locking rod 7 on the movable seat 4 and ensures the locking effect between the locking rod 7 and the locking groove 13.

[0026] The support rod 6 is provided with an assist rod 8 on the outer side of one end near the first connecting plate 5. The assist rod 8 makes it easier for the operator to drive the support rod 6 to rotate the locking rod 7, thus improving the convenience of the operator to rotate the locking rod 7.

[0027] Both the fixed base 3 and the movable base 4 are provided with clamping grooves 9. The clamping grooves 9 are provided with clamping plates 10 in an arc shape. The inner end face of the clamping plate 10 is provided with multiple compression springs connected to the inner wall of the clamping groove 9. Through the combination of clamping plate 10 and compression springs, it is possible to clamp and fix cables of various sizes to a certain extent, while avoiding the movable base 4 from hard squeezing the cable during the process of the locking rod 7 rotating and locking into the locking groove 13, which would cause damage to the cable.

[0028] The working principle of this utility model is as follows:

[0029] In use, the cable is first connected to the distribution box 1, positioning it between the fixed seat 3 and the movable seat 4. The movable seat 4 is pressed to move towards the fixed seat 3, thus clamping and fixing the cable. Then, the assist rod 8 drives the support rod 6 to rotate the locking rod 7, causing it to engage with the locking groove 13 in the second connecting plate 12. Finally, the movable seat 4 is loosened, locking the locking rod 7 in the locking groove 13, thus limiting and fixing the moved seat 4 after displacement, achieving stable constraint on the cable position. This invention can arrange the cables in the distribution box 1 in an orderly manner, avoiding tangled multiple cables and improving wiring efficiency. It also provides fixation and constraint for cables placed between the fixed seat 3 and the movable seat 4.
