A door support device for automotive painting

Abstract

This application relates to the field of automotive painting support technology, and in particular to a door support device for automotive painting, including a sleeve and a slide rod. The slide rod is provided with a telescopic mechanism with a compression spring extension function. The telescopic mechanism includes a spring, one end of which is fixedly connected to the slide rod, and the compression spring is attached to the slide rod. By extending and retracting the slide rod into the sleeve, and by creating multiple slots on the sleeve, the compression spring can be engaged in different slots as the slide rod slides within the sleeve. This allows the sleeve and slide rod to extend and retract freely and adjust their length. Rotating a collar connected to one end of the slide rod allows a plug to rotate freely and be mounted on a slider, enabling it to slide on its own. This allows the plug to flexibly fit into the process holes or reinforcing rib holes in the inner panel of the door, thus avoiding the situation where the support structure is fixed and the insertion is not properly positioned, leading to unstable support.

[0027] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0028] This application discloses a door support device for automotive painting.

[0029] like Figure 1-6 As shown, it includes a sleeve 1 and a slide rod 3. The slide rod 3 is provided with a telescopic mechanism with the extension and retraction function of a compression spring 5. The telescopic mechanism includes a spring 2. One end of the spring 2 is fixedly connected to the slide rod 3, and the compression spring 5 is attached to the slide rod 3.

[0030] The slide rod 3 is equipped with a rotating mechanism that has the function of rotating the ring 7. The rotating mechanism includes a fixed rod 8 and a limiting frame 9. The center ring of the ring 7 is fixedly connected to the fixed rod 8. One end of the fixed rod 8 is fixedly connected to the limiting frame 9. A slide rail frame 11 is slidably connected to the limiting frame 9. A slider 12 is slidably connected to the slide rail frame 11.

[0031] Please see Figure 3 and Figure 5 The inner wall of the sleeve 1 is provided with a groove 100. The bottom end of the slide rod 3 is fixedly connected to a limit block, which is slidably connected to the groove 100. Multiple slots 101 are passed through the inner and outer walls of the sleeve 1. A spring 2 is fixedly connected to the inner wall of one end of the sleeve 1. The spring 2 rebounds to drive the slide rod 3 to slide out automatically along the groove 100.

[0032] Please see Figure 4 The slide rod 3 has a groove 32, and a rivet 4 is fixedly connected to the groove 32. The compression spring 5 is sleeved on the compression spring 5, which is located in the slot 101. The slide rod 3 moves in the sleeve 1. When the slide rod 3 moves to the appropriate slot 101 in the sleeve 1, the compression spring 5 will automatically rebound and lock into the slot 101, thereby completing the positioning of the sleeve 1 and the slide rod 3.

[0033] Please see Figure 2 and Figure 3 One end of the sleeve 1 is provided with a mounting hole 30. A threaded hole 31 is provided with a mounting hole 30 through it. A nut 6 is threadedly connected to the threaded hole 31. One end of the nut 6 abuts against the outer circumference of the collar 7. The collar 7 is rotatably connected in the mounting hole 30. The collar 7 can rotate in the mounting hole 30 and is locked by the nut 6 abutting against the outer circumference of the collar 7. At the same time, the rotation of the collar 7 drives the fixing rod 8 and the limiting frame 9 to rotate synchronously.

[0034] Please see Figure 2 A threaded hole 90 is passed through one side of the limiting frame 9. A nut 10 is threadedly connected to the threaded hole 90. One end of the nut 10 abuts against the slide frame 11. The slide frame 11 can slide up and down in the limiting frame 9. The position of the slide frame 11 after lifting and lowering is locked by tightening the nut 10.

[0035] Please see Figure 2 A threaded rod 14 is vertically threaded onto the slide rail frame 11. The slider 12 has a threaded hole. The threaded rod 14 is threaded into the threaded hole of the slider 12. One end of the threaded rod 14 is fixedly connected to a throttle 140. Rotating the throttle 140 causes the slider 12 to rotate in the threaded rod 14. At the same time, the slider 12 is limited by the slide rail frame 11, so that it can only move up and down.

[0036] Please see Figure 1 and Figure 2 A rod 13 is fixedly connected to one side of the slider 12, and a hook 15 is fixedly connected to one end of the sleeve 1. The hook 15 is used to hook the B-pillar or C-pillar area of ​​the door frame edge and is a metal pin inserted when the door lock is closed. The rod 13 is used to insert into the process hole or reinforcing rib hole of the inner panel of the door. The setting of the hook 15 and the rod 13 can play the role of fixing the door.

[0037] The implementation principle of a door support device for automobile painting according to an embodiment of this application is as follows:

[0038] The hook 15 is used to hook onto the B-pillar or C-pillar area of ​​the door frame edge. It is a metal pin that the door latch inserts when closed. The insert rod 13 is used to insert into the process hole or reinforcing rib hole of the inner panel of the door. The hook 15 and the insert rod 13 are used to fix the door.

[0039] When it is necessary to fix the car door, the operator only needs to manually press the compression spring 5 to press the compression spring 5 into the slide groove 100. Then the spring 2 rebounds and drives the slide rod 3 to push in the sleeve 1, thereby achieving the rapid extension and retraction of the sleeve 1 and the slide rod 3.

[0040] If the sleeve 1 and the slide rod 3 need to be stretched to a certain length, simply slide the compression spring 5 into the nearby slot 101 to make the compression spring 5 lock into the slot 101, thereby locking the position of the slide rod 3 after stretching.

[0041] When the insertion rod 13 is inserted into the process hole or reinforcing rib hole of the inner door panel, and its position is higher or lower than that of the hook 15 hooking the B-pillar or C-pillar area of ​​the door frame edge, simply turn the handle 140. The handle 140 drives the threaded rod 14 to rotate. The threaded rod 14 and the slider 12 rotate and drive them to rise and fall. The rise and fall of the slider 12 can make the position of the insertion rod 13 flush with the process hole or reinforcing rib hole of the inner door panel.

[0042] When the insertion rod 13 is inserted into the process hole or reinforcing rib hole of the inner panel of the car door, it is only necessary to rotate the collar 7. The collar 7 drives the fixing rod 8, the limiting frame 9, the second nut 10, the sliding bracket 11, the slider 12 and the insertion rod 13 to rotate synchronously. After rotating to the level position, tighten the first nut 6 so that it abuts against the outer circumference of the collar 7 to lock it.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
