Description

Technical Field

[0001] The utility model relates to an adjustable universal fixing device, belonging to the technical field of rail transportation. Background Art

[0002] Due to vehicle structural design requirements, the control host is typically installed in an onboard electrical cabinet. To achieve subway vehicle functionality, a large number of cables must be routed from the undercarriage to the passenger compartment. The lower portion of the low-voltage cabinet (SEC2L) at the passenger compartment's second-end is equipped with a lead-in port, which is also located on the vehicle floor. Below this port is the second-end junction box at the undercarriage. To ensure a sealed seal, silicone foam is used for filling.

[0003] During vehicle manufacturing, the silicone foam used takes 8-10 hours to dry. The wiring harnesses that run from the subway underframe to the passenger compartment are over ten meters long and heavy. The harnesses are pulled out from the entry port and filled with foam before curing. During the curing process, the weight of the cables can easily squeeze and deform the foam, creating gaps between the cured foam and the harness, compromising the sealing effect. The wiring harnesses that run from the subway underframe to the passenger compartment are numerous and long. After being pulled up from the entry port at each workstation, the harnesses are routed to each of four production stations for wiring. Throughout the day, the harnesses are protected with protective cloth. Once the protective cloth is removed from the wiring station, the harnesses can become tangled, requiring significant time for wiring, sorting, and routing.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to ordinary technicians in this field.

[0030] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] See Figures 1 to 7 This embodiment provides an adjustable universal fixing device, comprising a main body 1, a first bundling member 2, a second bundling member 3, and a fixing member 4. The fixing member 4 is configured as a U-shaped structure and can be made of rubber. The first bundling member 2 and the fixing member 4 are mounted on opposite sides of the main body 1, i.e., the first bundling member 2 and the fixing member 4 are located on opposite sides of the main body 1. Multiple fixing members 4 are mounted on corresponding sides of the main body 1, and the multiple fixing members 4 are arranged on the main body 1 in an interval from top to bottom.

[0032] Multiple connecting rods 5 are spaced apart on one side of the main member 1, each of which is vertically fixed to the main member 1. Each first tying member 2 is slidably connected to a corresponding connecting rod 5. A limiter 6 is provided on the main member 1 to limit the relative movement of the first tying members 2 relative to the connecting rod 5.

[0033] During use, the main body 1 is placed near the upper opening 23, and each first bundling piece 2 is pre-adjusted to slide along the corresponding connecting rod shaft 5, and the distance between each first bundling piece 2 and the main body 1 is determined and then limited by the limit piece 6. Figure 7, lead the wire harness 22 out from the lead-in port 23, and each wire harness 22 is led vertically upward along the first bundling piece 2, and fixed by wrapping the wire harness 22 and the first bundling piece 2 with a cable tie. Leading out and fixing vertically upward can fully seal the foam filling between the vertically upward wire harnesses 22, avoiding the occurrence of deviation of the wire harness 22, squeezing and deformation of the foam, etc. After leading the wire harness 22 to the top of the main body 1 along the first bundling piece 2, continue to lead it along each second bundling piece 3, and continue to fix it with a cable tie around the wire harness 22 and the second bundling piece 3. Leading the wire harness 22 from vertically upward to horizontal transition can disperse the vertical force of the wire harness 22 on the adjustable universal fixture. The horizontal transition wire harness 22 exerts downward pressure on the adjustable universal fixture, which can also improve the stability of the adjustable universal fixture. Each wire harness 22 is guided along the second binding member 3 to the corresponding fixtures 4 spaced from top to bottom. Each wire harness 22 is coiled and hung in the corresponding U-shaped fixture 4, completing the wire harness 22 lead-out port 23. The passage of each wire harness 22 through the first binding member 2, the second binding member 3, and the fixture 4 not only aids in the sealing and restraint of the foam adhesive on the wire harness 22, but also organizes the lead-out wire harnesses 22, preventing them from becoming tangled and causing a significant amount of time-consuming subsequent wire management and branching.

[0034] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The first binding member 2 is configured as a first transverse rod 7 and a first vertical rod 8. The first vertical rod 8 is a tubular body. One end of each of the two first vertical rods 8 is perpendicularly mounted on the first transverse rod 7, with a distance between the two vertical rods. The other ends of the two vertical rods are correspondingly sleeved on the outer circumference of the connecting rod shaft 5, thereby enabling the first binding member 2 to move closer to or farther from the main member 1 along the connecting rod shaft 5.

[0035] In some embodiments, Figure 6 The limiting member 6 includes a latch seat 9, a T-shaped latch 10, and a limiting hole 11. Multiple limiting holes 11 are spaced apart along the axial direction of the first vertical rod 8. The latch seat 9 is fixed to the main member 1 via countersunk screws. The latch seat 9 is provided with a positioning seat 12, a first retaining slot 13, and a second retaining slot 14.

[0036] The T-shaped latch 10 includes a limiting rod 16 and a fixing rod 17. The limiting rod 16 and the fixing rod 17 are vertically connected to each other. Specifically, one end of the limiting rod 16 is vertically fixed to the rod body of the fixing rod 17. During assembly, after the bottom end of the limiting rod 16 passes through the fixing seat, it is inserted into the limiting hole 11 on the first vertical rod 8, and the limiting rod 16 is rotated so that the fixing rod 17 is stuck in the first slot 13, thereby limiting the first bundling member 2 to prevent it from sliding relative to the connecting rod shaft 5. After the bottom end of the limiting rod 16 is withdrawn from the limiting hole 11, the limiting rod 16 is rotated so that the fixing rod 17 is stuck in the second slot 14. In this way, the distance between the first bundling member 2 and the main body 1 can be freely adjusted.

[0037] Two positioning seats 12 are positioned vertically on the latch seat 9, and the two positioning posts are each provided with a positioning hole 15, the centers of which are aligned. A limiting rod 16 passes through the two positioning holes 15 and can be adjusted up and down to provide a better guide. The overall structure of the limiting member 6 is simple, making it easy for the operator to adjust it. This limiting member 6 can also adopt the adjustable limit assembly known in the prior art.

[0038] Specifically, the first clamping slot 13 and the second clamping slot 14 are distributed on opposite sides relative to the limiting rod 16 assembled in the positioning hole 15. This arrangement is conducive to adapting to the operator's regular operating behavior and improving the adjustment speed.

[0039] In some embodiments, the main body 1 is configured as a box body in the longitudinal direction. The second bundling member 3 is fixed to the top of the box body. The first bundling member 2 and the fixing member 4 are symmetrically arranged on both sides of the box body. The connecting rod shaft 5 is vertically fixed inside the box body, and a through hole is provided in the box body portion corresponding to the free end of each connecting rod shaft 5. The first vertical rod 8 passes through the through hole and is sleeved on the connecting rod shaft 5. Correspondingly, a limit member 6 that cooperates with the first bundling member 2 is installed above the through hole. The width of the box body is slightly wider than the width of the upper hole of the vehicle body by 35 cm, and the height is 100 cm.

[0040] In some embodiments, as Figure 1 and Figure 2 The adjustable universal fixing device also includes a C-shaped base 18. A connecting plate 19 extends downward from the bottom of the main body 1, and the C-shaped base 18 is fixed below the connecting plate 19. A counterweight is assembled inside the C-shaped base 18. The C-shaped base 18 is placed on one side of the lead-in port 23. The C-shaped structure can help avoid the lead-in port 23, ensuring that the wire harness 22 is led out closer to the first bundling member 2, forming a vertical lead-out effect. The counterweight ensures the stability of the overall support of the adjustable universal fixing device.

[0041] The second binding member 3 includes a second crossbar 20 and a second vertical bar 21. The two vertical bars are vertically spaced apart on the second crossbar 20, with their other ends vertically fixed to the top of the main member 1. The fixing members 4 are positioned so that the fixing member 4 near the bottom of the main member 1 is positioned at a distance of more than 35 cm from the bottom of the main member 1, preventing the wiring harness 22 from dragging on the ground and protecting the wiring harness 22.
