Detailed Implementation
[0017] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.
[0018] like Figure 1-2As shown, a rail transit harness spacing adjustment installation assembly includes a first snap-fit component 1, a second snap-fit component 2 slidably connected to the free end of the first snap-fit component 1, a first installation area 3 formed between the first snap-fit component 1 and the second snap-fit component 2, and another first snap-fit component 1 slidably connected to the free end of the second snap-fit component 2, forming a second installation area 4. A baffle 5 is connected between the first snap-fit component 1 and the second snap-fit component 2 above the second installation area 4. The first snap-fit component 1 includes an inverted first L-shaped plate 6, an upper guide plate 7 slidably connected to the free end of the horizontal section of the first L-shaped plate 6, and a horizontal second L-shaped plate 8, the outer part of the vertical section of the second L-shaped plate 8 being integrally formed with the upper guide plate 7. A lower guide plate 9 slidably connected to the free end of the horizontal section of the second L-shaped plate 8 is integrally formed with the vertical section of the adjacent first L-shaped plate 6.
[0019] Preferably, a vertical groove 10 is formed on the vertical section of the first L-shaped plate 6, and a connecting block 11 is slidably connected to the groove 10. A limiting screw 12 for fixing the first L-shaped plate 6 is inserted into the connecting block 11. The vertical section structure of the second L-shaped plate 8 is the same as that of the first L-shaped plate 6. The limiting screw 12 passes through the connecting block 11 to avoid damage to the first L-shaped plate 6 or the second L-shaped plate 8 during the tightening of the limiting screw 12. If the connecting block 11 is damaged, it can be replaced independently, reducing replacement costs.
[0020] Preferably, a limiting protrusion 13 is provided at the bottom of the slide groove 10, and the bottom of the connecting block 11 located in the slide groove 10 abuts against the limiting protrusion 13. The setting of the limiting protrusion 13 prevents the first L-shaped plate 6 and the second L-shaped plate 8 from displacing outward due to the reverse force of the wire harness after the connecting block 11 is fixed, thereby improving the stability of the wire harness fixing.
[0021] Preferably, the free ends of the first L-shaped plate 6 and the second L-shaped plate 8 are provided with horizontal snap-fit grooves 14, and the inner wall of the snap-fit groove 14 is provided with a snap-fit strip 15. The sides of the upper guide plate 7 and the lower guide plate 9 are provided with snap-fit grooves 16 that cooperate with the snap-fit strip 15.
[0022] Preferably, both the first snap-fit component 1 and the second snap-fit component 2 are made of plastic. The use of plastic components makes the entire product lightweight, reduces production costs, and facilitates disassembly and maintenance.
[0023] During operation, the operator first fixes the positions of the connecting block 11 and the first L-shaped plate 6 in the first snap-fit component 1 at the head end. By connecting the free end of the limiting screw 12 to the mounting surface, the position of the first L-shaped plate 6 is fixed. After fixing, a set of wire harnesses is placed in the first mounting area 3. Then, the second snap-fit component 2 is slidably connected to the free end of the horizontal section of the first L-shaped plate 6. The size of the first mounting area 3 is adjusted horizontally according to the number of wire harnesses. After adjustment, the position of the second L-shaped plate 8 is fixed by the limiting screw 12. After fixing, the next set of wire harnesses is placed in the second mounting area 4. Then, the next set of first snap-fit components 1 is slidably connected to the free end of the horizontal section of the second L-shaped plate 8 in the same way. After completion, a baffle 5 is covered on the top of the second mounting area 4. The baffle 5 abuts against the upper surface of the connecting block 11 through the head end face of the limiting screw 12.
