At this time, the flip tooth plate is driven by the square hanger to move downward synchronously. The downward-moving flip tooth plate drives the flip gear to rotate, and then drives the tightening tooth plate to move up, so as to drive the two slides at the end of the push frame to slide upward in the accommodating groove, thereby driving the top seat to move upward to tighten against the lower end of the horizontal frame of the aluminum alloy bracket, so as to tie the hanger to the horizontal frame of the aluminum alloy bracket to complete the installation of the box body. The process does not require additional installation operations on the box body, thereby effectively facilitating the installation and improving the installation efficiency.

[0015] 2. When the push frame is moving upward, the upper locking ear will use its own inclined surface to push the lower locking ear, so that the lower locking ear can move forward. At this time, the tightening spring contracts and deforms. When the top seat is tightened against the lower end of the horizontal frame of the aluminum alloy bracket, the upper locking ear just moves to the top of the lower locking ear. At this time, the tightening spring recovers its deformation to push the lower locking ear to reset, so that the lower locking ear moves to the bottom of the upper locking ear to limit the upper locking ear, and then limit the top seat tightened on the aluminum alloy bracket, so that the hanger will not fall off the aluminum alloy bracket and cause the box body to fall off, thereby ensuring the firmness after installation.

[0016] 3. When the flip gear on the flip shaft rotates and drives the top gear plate to move up, it will also synchronously drive the flip frame to flip, so that the clamping seats at the ends of the two flip frames can move toward each other to gather together and hold tightly to the outside of the vertical frame of the aluminum alloy bracket to limit the box body, so as to ensure that the box body will not shift after installation, so as to further ensure the firmness after installation.

DETAILED DESCRIPTION

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] like Figure 1-Figure 7 The protective box for automobile wiring harness shown in the figure includes a box body 1, and a square suspension rod 2 is fixedly installed in the middle of the upper end of the box body 1. Since the box body 1, that is, the cassette-type wiring harness box, is a prior art and has been widely used, it is not elaborated on here. The outer surface of the square suspension rod 2 is fitted with a suspension seat 3. The square suspension rod 2 and the suspension seat 3 play the role of hanging the box body 1. Two hangers 4 extend symmetrically from the upper end of the suspension seat 3. The upper end of the hanger 4 is curved, which can facilitate the hanger 4 to be hung on the aluminum alloy bracket 3. 4, the front ends of the two hangers 4 are penetrated with a receiving groove 28, the interior of the receiving groove 28 is fitted with a slide 17, and the receiving groove 28 plays the role of accommodating the slide 17. The upper rear end of the slide 17 is installed with a top seat 15, and the top seat 15 can be placed on the lower end of the horizontal frame of the aluminum alloy bracket 34, so that the hangers 4 hung on the horizontal frame of the aluminum alloy bracket 34 will not fall. A flip fixture is installed on the side of one of the hangers 4, which is connected to the square hanger 2 and the slide 17.

[0027] There are wire passing openings 31 on both sides of the box body 1, which serve to allow the wires in the box body 1 to extend out. A box cover 32 is installed at the front end of the box body 1, and the box cover 32 serves to seal the box body 1. The upper end of the square suspension rod 2 is inlaid with a limiting cap 14, and the lower end surface of the limiting cap 14 is attached to the upper end of the suspension seat 3. The limiting cap 14 serves to prevent the square suspension rod 2 and the suspension seat 3 from separating. Reinforcement plates 33 are obliquely extended near the lower edge on both sides of the square suspension rod 2. The reinforcement plates 33 serve to improve the connection strength between the square suspension rod 2 and the box body 1, and the ends of the reinforcement plates 33 are fixed to the box body 1.

[0028] Guide ribs 27 extend from both sides of the interior of the accommodating groove 28, and guide grooves 29 are provided on both sides of the slide 17. The cooperation between the guide ribs 27 and the guide grooves 29 serves to vertically guide the slide 17. The guide ribs 27 fit through the interior of the guide grooves 29. A fixing column 16 is fixedly installed at the lower end of the top seat 15, and the end of the fixing column 16 is fixed to the slide 17. The fixing column 16 serves to fix the top seat 15 and the slide 17 together.

[0029] The flipping fixture includes two flip gears 21 symmetrically mounted on one of the hangers 4. The opposite ends of the two flip gears 21 are engaged with a flip tooth plate 12. The lower end of the flip tooth plate 12 is connected to the synchronous frame 10. The flip tooth plate 12 drives the flip gear 21 to rotate. The lower end of the synchronous frame 10 is fixed to the square hanger 2. The synchronous frame 10 fixes the flip tooth plate 12 and the square hanger 2. A pushing frame 9 is fixedly installed between the front ends of the two slides 17. A tightening tooth plate 22 is fixedly installed on the upper end of the pushing frame 9 near the middle. The pushing frame 9 drives the two slides 17 The function of synchronous movement is that the tightening tooth plate 22 is engaged with the flip gear 21 in front, and the flip gear 21 can drive the tightening tooth plate 22 to move, thereby driving the pushing frame 9 to move, and the box body 1 moves downward under its own weight, driving the square suspension rod 2 to slide down on the suspension seat 3. At this time, the flip tooth plate 12 is driven by the square suspension rod 2 and moves downward synchronously. The downward-moving flip tooth plate 12 drives the flip gear 21 to rotate, thereby driving the tightening tooth plate 22 to move upward, so as to drive the two slides 17 at the end of the pushing frame 9 to slide upward in the accommodating groove 28, thereby driving the top seat 15 to move upward to tighten against the lower end of the cross frame of the aluminum alloy bracket 34.

[0030] The interior of the flip gear 21 is coaxially penetrated by a flip shaft 11, and a shaft frame 8 is fixedly installed on the side of one of the hangers 4. The flip shaft 11 serves to support the flip gear 21. The flip shaft 11 is rotatably installed on the end of the shaft frame 8. The shaft frame 8 serves to support the flip shaft 11. A flip frame 6 is fixedly installed on the middle part of the outer surface of the flip shaft 11. The flip shaft 11 drives the flip frame 6 to flip. A clamp seat 7 is fixedly installed on the end of the flip frame 6. The clamp seat 7 can clamp the outer side of the stand of the aluminum alloy bracket 34 to limit the box body 1 so that the box body 1 will not shift.

[0031] The upper end of the synchronous frame 10 is penetrated and inlaid with a connecting block 13. The end of the connecting block 13 is fixed to the flip tooth plate 12. The connecting block 13 plays the role of fixing the flip tooth plate 12 and the synchronous frame 10 together. The front end edge of the hanger 4 is fixedly installed with a protruding seat 5. A push sleeve 19 is elastically installed on the protruding seat 5. The protruding seat 5 plays the role of carrying the bearing rod 24. The upper end of the pushing frame 9 is symmetrically installed with two upper locking ears 20. A lower locking ear 25 is extended on one side of the push sleeve 19. The upper locking ear 20 and the lower locking ear 25 are engaged with each other, which can limit the top seat 15 so that the top seat 15 will not shift by itself after installation. The lower end of the ear 20 fits into the upper end of the lower locking ear 25, and the upper end of the upper locking ear 20 and the lower end of the lower locking ear 25 are both arranged with an inclined surface, so that when the pushing frame 9 moves upward, the upper locking ear 20 can use its own inclined surface to push the lower locking ear 25, so that the lower locking ear 25 can move forward. At this time, the tightening spring 23 contracts and deforms. When the top seat 15 is tightened to the lower end of the horizontal frame of the aluminum alloy bracket 34, the upper locking ear 20 just moves to the top of the lower locking ear 25. At this time, the tightening spring 23 recovers its deformation to push the lower locking ear 25 to reset, so that the lower locking ear 25 moves to the bottom of the upper locking ear 20 to limit the upper locking ear 20.

[0032] The front end of the upper locking ear 20 is fixedly installed with a fixed ear frame 26, and the lower end of the fixed ear frame 26 is fixed to the upper edge of the push frame 9. The fixed ear frame 26 plays a role in fixing the upper locking ear 20. The interior of the push sleeve 19 is fitted with a load-bearing rod 24, which plays a role in carrying the push sleeve 19. The load-bearing rod 24 passes through the front and rear ends of the push sleeve 19, and the end of the load-bearing rod 24 is fixed to the extended seat 5. A limiting lug 18 extends from the other side of the push sleeve 19. The limiting lug 18 prevents the push sleeve 19 from rotating, and the limiting lug 18 passes through the side of the extended seat 5.

[0033] A tightening spring 23 is wound around the outside of the carrying rod 24, one end of the tightening spring 23 is fixed to the push sleeve 19, and the other end of the tightening spring 23 is fixed to the extension seat 5. The tightening spring 23 pushes the push sleeve 19 to reset the lower locking ear 25. A limiting groove 30 is provided on the side of the extension seat 5, and the limiting lug 18 fits into the inside of the limiting groove 30. The limiting groove 30 can cooperate with the limiting lug 18 to limit the reset position of the push sleeve 19.

[0034] During installation, the hanger 4 is propped up and hung on the horizontal frame of the aluminum alloy bracket 34. At this time, the box body 1 moves down under its own weight, thereby driving the square hanger 2 to slide down on the hanger 3. At this time, the flip tooth plate 12 is driven by the square hanger 2 and moves down synchronously. The downward flip tooth plate 12 drives the flip gear 21 to rotate, thereby driving the tightening tooth plate 22 to move up, so as to drive the two slides 17 at the end of the pushing frame 9 to slide up in the accommodating groove 28, thereby driving the top seat 15 to move up to tighten against the lower end of the horizontal frame of the aluminum alloy bracket 34. In this process, when the pushing frame 9 moves up, the upper locking ear 20 will use its own inclined surface to push the lower locking ear 25, so that the lower locking ear 25 can move forward. At this time, the tightening spring 23 contracts and deforms, and the top seat 15 is tightened to the lower end of the horizontal frame of the aluminum alloy bracket 34. When the upper locking ear 20 is just moved to above the lower locking ear 25, the tightening spring 23 recovers its deformation to push the lower locking ear 25 to reset, so that the lower locking ear 25 moves to below the upper locking ear 20 to limit the upper locking ear 20, and then limit the top seat 15 that is tightened on the aluminum alloy bracket 34, thereby binding the hanger 4 to the horizontal frame of the aluminum alloy bracket 34, and the flip gear 21 on the flip shaft 11 rotates to drive the tightening tooth plate 22 to move upward while also synchronously driving the flip frame 6 to flip, so that the clamping seats 7 at the ends of the two flip frames 6 can move toward each other, to gather together, and hold tightly to the outer side of the vertical frame of the aluminum alloy bracket 34, to limit the box body 1, so that the box body 1 will not shift, thereby completing the installation of the box body 1.
