[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The present application embodiment discloses a wiring harness fixing device inside a power distribution cabinet. Figure 1-3 , a wiring harness fixing device inside a power distribution cabinet, comprising a fixing plate 1, a longer middle section outer wall of the fixing plate 1 is fixedly connected with a slide rail 2, an outer wall of the slide rail 2 is movably connected with a slider 4, the number of the sliders 4 can be multiple, an elastic buckle 5 is fixedly installed on the outer wall of the slider 4 through a fixing seat 18, a clamping mechanism is arranged on the outer wall of the elastic buckle 5, a plurality of tooth grooves 3 are opened on the top outer wall of the slide rail 2, and an adjustment mechanism for adjusting the position of the elastic buckle 5 is arranged on the inner wall of the slider 4;

[0024] The clamping mechanism includes two arc-shaped clamping plates 6 symmetrically arranged inside the elastic buckle 5, and the outer walls of the two arc-shaped clamping plates 6 facing away from each other are fixedly connected with multiple limit rods 9. The end of the limit rod 9 away from the arc-shaped clamping plate 6 passes through the elastic buckle 5 and is fixedly connected with an extrusion plate 11. The outer walls of the multiple limit rods 9 are installed with a first spring 10, and the first spring 10 is located between the extrusion plate 11 and the outer wall of the elastic buckle 5. The outer walls of the middle sections of both sides of the elastic buckle 5 are provided with threaded rings 7, and the inner walls of the threaded rings 7 are threadedly connected with threaded columns 8.

[0025] The adjustment mechanism includes pressing blocks 13 symmetrically slidably connected to the outer walls of both sides of the slider 4 , and a clamping block 14 is fixedly connected to the bottom outer wall of one end of the pressing block 13 facing the inside of the slider 4 , and the clamping block 14 is adapted to be clamped with the plurality of tooth grooves 3 .

[0026] The adjustment mechanism also includes a fixed block 15 fixedly connected to the outer wall of the bottom middle section of the slider 4, and two second springs 17 are fixedly connected to the outer walls on both sides of the fixed block 15. The end of the second spring 17 away from the fixed block 15 is fixedly connected to the outer wall of one end of the pressing block 13.

[0027] A T-shaped limit block 16 is welded to the bottom outer wall of the fixed block 15, and the T-shaped limit block 16 is slidably connected to the inner wall of the slide rail 2. When the T-shaped limit block 16 slides on the inner wall of the slide rail 2, the slider 4 can be fixed to the outer wall of the slide rail 2, so that the slider 4 will not be separated from the slide rail 2 when sliding on the outer wall of the slide rail 2.

[0028] The outer walls of the middle sections of the two arc-shaped clamping plates 6 facing each other are fixedly connected with abutment blocks 20 , and the opposite ends of the two threaded columns 8 respectively abut against the two abutment blocks 20 .

[0029] One end of the two threaded columns 8 away from the abutment block 20 is fixedly connected with a knob 12 , and the knob 12 is located between the two extrusion plates 11 .

[0030] The outer wall of the fixing plate 1 is provided with a plurality of fixing holes 19 , and the plurality of fixing holes 19 are evenly distributed at the four corner edge positions of the fixing plate 1 .

[0031] The implementation principle of the wiring harness fixing device inside the power distribution cabinet of the embodiment of the present application is as follows: when in use, firstly, the fixing plate 1 is fixed to the inner wall of the power distribution box by screws through the multiple fixing holes 19 on the fixing plate 1, and then the multiple sliders 4 are installed on the outer wall of the slide rail 2, and the T-shaped limit block 16 inside the slider 4 is inserted from one end of the slide rail 2, so that the T-shaped limit block 16 slides inside the slide rail 2 to achieve the installation of the multiple sliders 4, and then the wiring harness of the electrical components inside the fixing plate 1 is buckled in the elastic buckle 5;

[0032] The spacing between the two arc-shaped clamping plates 6 is adjusted according to the size of the wiring harness, and the knob 12 is turned. The knob 12 drives the threaded column 8 to rotate on the inner surface of the threaded ring 7, and then the threaded ring 7 drives the threaded column 8 to move into the elastic buckle 5. The end of the threaded column 8 will abut against the abutment block 20 to drive the two arc-shaped clamping plates 6 to move inward, and the two arc-shaped clamping plates 6 will move relative to each other to clamp and fix the wiring harness. It is worth noting that when the two arc-shaped clamping plates 6 move inward, the limiting rod 9 will slide inward on the outer wall of the elastic buckle 5, and the limiting rod 9 will drive the extrusion plate 11 to move close to the elastic buckle 5. The extrusion plate 11 cooperates with the elastic buckle 5 to squeeze the first spring 10, and the first spring 10 deforms to generate elastic force;

[0033] At the same time, the spacing between the multiple sliders 4 can be adjusted by the adjustment mechanism, so that the multiple sliders 4 can be reasonably distributed and fixed according to the positions of each wiring harness. The two pressing blocks 13 are pressed inwardly, and the two pressing blocks 13 move toward the inside of the slider 4, and the ends thereof squeeze the multiple second springs 17. The multiple second springs 17 are deformed to generate elastic force, and at the same time, the pressing block 13 drives the clamping block 14 to move toward the direction of the fixing block 15, so that it is disengaged from the tooth groove 3, and the fixation of the slider 4 is released. At this time, the slider 4 can drive the T-shaped limit block 16 and the elastic buckle 5 to move. The second spring 17 is used to move the clamping block 14 to adjust the position of the elastic buckle 5 and the wiring harness. When the position is adjusted appropriately, the pressing block 13 is released. The two pressing blocks 13 are reset outward under the elastic force of the second springs 17. The pressing block 13 drives the clamping block 14 to re-engage with a tooth groove 3 at the new position to fix the slider 4. It is worth noting that the elastic travel of the second spring 17 can just make the clamping block 14 engage with the inner wall of the tooth groove 3, thereby avoiding the elastic travel of the second spring 17 being decisive, resulting in the two pressing blocks 13 being ejected from the outside of the slider 4 by the second spring 17.

[0034] Such an adjustment mechanism not only enables the multiple sliders 4 to be adjusted and fixed according to the positions of the multiple wire harnesses, but also can adjust the spacing between the multiple wire harnesses during maintenance, reasonably utilize the arrangement space between the wire harnesses, and provide suitable maintenance space for operators by expanding or reducing the spacing between the wire harnesses. When necessary, the sliders 4 can also be quickly removed from the slide rails 2 through the adjustment mechanism for maintenance. It is simple to use, easy to install and maintain;

[0035] When disassembling the wiring harness, by rotating the knob 12 in the opposite direction, the knob 12 drives the threaded column 8 to rotate on the inner surface of the threaded ring 7, driving the threaded column 8 to move toward the outer wall of the elastic buckle 5, so that the end of the threaded column 8 located inside the elastic buckle 5 no longer abuts against the abutment block 20. At this time, the elastic force generated by the first spring 10 will press against the extrusion plate 11 outward, and the extrusion plate 11 generates an outward thrust, which drives the limiting rod 9 to move outward, and the limiting rod 9 pulls the arc-shaped clamping plate 6 to reset, and the two arc-shaped clamping plates 6 are away from the wiring harness, releasing the clamping of the wiring harness, and the wiring harness can be easily disassembled from the elastic buckle 5.
