Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a foldable auto repair reclining board, including a first reclining board frame 1. A first threaded rod 8 is rotatably connected to the inner wall of the first reclining board frame 1. A first movable frame 7 is threadedly connected to the outer wall of the first threaded rod 8. A support rod 6 is rotatably connected to the top of the first movable frame 7. A backrest 4 is rotatably connected to the top of the support rod 6. A cushion 5 is fixedly connected to the outer wall of the backrest 4. A first bevel gear 9 is fixedly connected to the left side of the first threaded rod 8. A second bevel gear 10 is meshed with the tooth end of the first bevel gear 9. A transmission rod 11 is fixedly connected to the outer wall of the second bevel gear 10. A rotating handle 12 is fixedly connected to the outer wall of the transmission rod 11. A fixing component is provided on the left side of the first reclining board frame 1.

[0025] Specifically, rotating the handle 12 on the outer wall of the first reclining frame 1 causes the handle 12 to drive the first threaded rod 8 to rotate through the transmission rod 11, the second bevel gear 10, and the first bevel gear 9. This allows the first movable frame 7 to move the support rod 6 through its threaded connection with the first threaded rod 8. The support rod 6 then drives the backrest 4 to rotate. The backrest 5 prevents maintenance personnel from experiencing soreness from lying on the backrest 4 for extended periods. By rotating the handle 12, the angle of the backrest 4 can be changed, allowing for convenient adjustment of the backrest 4's angle.

[0026] Reference Figure 1 , Figure 4 and Figure 5The fixing assembly includes a second reclining frame 2, which is rotatably connected to the outer wall of the first reclining frame 1. A second threaded rod 13 is rotatably connected to the inner wall of the second reclining frame 2. Two second movable frames 14 are threadedly connected to the outer wall of the second threaded rod 13. A support frame 15 is rotatably connected to the bottom end of the second movable frame 14. A connecting frame 16 is rotatably connected to the bottom end of the support frame 15. Two rubber pads 17 are fixedly connected to the bottom end of the connecting frame 16.

[0027] Specifically, by rotating the handle 12 on the outer wall of the second reclining board frame 2, the handle 12 drives the second threaded rod 13 to rotate, causing the two second movable frames 14 on the outer wall of the second threaded rod 13 to move inward together. At the same time, the support frame 15, which is rotatably connected to the second movable frame 14, drives the connecting frame 16 to move downward, allowing the rubber pad 17 to contact the ground. Through the friction with the ground, the second reclining board frame 2 is fixed, thereby achieving the effect of fixing the reclining board.

[0028] Reference Figure 1 The first reclining frame 1 is fixedly connected with multiple casters 3, and the second reclining frame 2 is fixedly connected with multiple casters 3.

[0029] Specifically, by installing four casters 3 at the bottom of the first reclining board frame 1 and the second reclining board frame 2 respectively, it is not only convenient to move the reclining board, but also the casters 3 can support the first reclining board frame 1 and the second reclining board frame 2 after the reclining board is unfolded, thus preventing the reclining board from folding at the folding point.

[0030] Reference Figure 2 and Figure 3 The backrest 4 is rotatably connected to the inner wall of the first reclining frame 1, the first movable frame 7 is slidably connected to the inner wall of the first reclining frame 1, the transmission rod 11 is rotatably connected to the inner wall of the first reclining frame 1, and the rotating handle 12 is rotatably connected to the outer wall of the first reclining frame 1.

[0031] Specifically, the first bevel gear 9 and the second bevel gear 10 are meshed and connected, and contact the outer wall of the first reclining frame 1. The first bevel gear 9 restricts the movement of the first threaded rod 8, and the second bevel gear 10 restricts the movement of the transmission rod 11. The transmission rod 11 can smoothly drive the second bevel gear 10 and the first bevel gear 9 by rotating the handle 12, so that the first threaded rod 8 can smoothly drive the first moving frame 7 to move. The front and rear ends of the first moving frame 7 slide on the inner wall of the first reclining frame 1, so that the first moving frame 7 can smoothly drive the support rod 6, so that the backing plate 4 rotates, thereby achieving the effect of stabilizing and adjusting the angle of the backing plate 4.

[0032] Reference Figure 4 and Figure 5The handle 12 is rotatably connected to the outer wall of the second reclining frame 2, and the connecting frame 16 is slidably connected to the outer wall of the second movable frame 14.

[0033] Specifically, when the two second movable frames 14 move outwards via the second threaded rods 13, the support frame 15 drives the connecting frame 16 to move upwards, and the connecting frame 16 contacts the second movable frames 14, so that the rubber pad 17 is away from the ground, thus facilitating the movement of the reclining board.

[0034] Reference Figure 1 The first reclining frame 1 is slidably connected to the outer wall of the second reclining frame 2, and the cushion 5 is slidably connected to the outer wall of the second reclining frame 2.

[0035] Specifically, by folding the reclining board so that the first reclining board frame 1 contacts the second reclining board frame 2, the space occupied by the reclining board can be reduced. The cushion 5 is sandwiched between the first reclining board frame 1 and the second reclining board frame 2, which can prevent the cushion 5 from getting dirty.

[0036] Working principle: By unfolding the reclining board, maintenance personnel can lie on the first reclining board frame 1 and the second reclining board frame 2. Then, the board is moved to the bottom of the car via the casters 3. After the reclining board is moved to the car repair location, the rotating handle 12 on the second reclining board frame 2 is turned. This causes the second threaded rod 13 to drive the two second moving frames 14 to move inward through the rotating handle 12. This causes the support frame 15 to drive the connecting frame 16 to move downward, so that the rubber pad 17 contacts the ground, thus fixing the second reclining board frame 2 and achieving the effect of fixing the reclining board.

[0037] After the reclining board is fixed, rotate the rotating handle 12 on the first reclining board frame 1, so that the transmission rod 11 drives the second bevel gear 10 and the first bevel gear 9 to rotate through the rotating handle 12, so that the first threaded rod 8 drives the first moving frame 7 to move to the right through the first bevel gear 9, so that the support rod 6 pushes the back plate 4 to rotate through the first moving frame 7 until the back plate 4 rotates to the appropriate position, and then stop rotating the rotating handle 12 to achieve the effect of conveniently adjusting the angle of the back plate 4.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
