[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a hanging device for painting car trunk lids, including a base plate 2. A fixing frame 1 is welded to the top and edge of the base plate 2. A sliding plate 8 is slidably connected to one side of the fixing frame 1, and a fixing block 5 is fixed to the other side of the sliding plate 8 by bolts. A rotating shaft 10 is rotatably connected to the inner wall of the fixing block 5 via bearings. A connecting frame 4 is fixed to the bottom end of the rotating shaft 10 by bolts, and a turntable 6 is fixed to the top end of the rotating shaft 10 by bolts. Multiple telescopic rods 11 are fixed to the outer circumference of the turntable 6 by bolts. A connecting plate 13 is fixed to the telescopic ends of two adjacent telescopic rods 11 by bolts. An insertion rod 14 is fixed to the bottom of the connecting plate 13 by bolts. Multiple slots 15 are evenly arranged on the outer circumference of the fixing block 5 and are used to insert the insertion rods 14. A driving assembly is provided on the inner wall of the turntable 6 to drive the two connecting plates 13 to move towards each other. The driving assembly includes a bidirectional threaded rod 12 rotatably connected to the inside of the turntable 6 via bearings. The bidirectional threaded rod 12 is threadedly connected to two connecting plates 13. By rotating the bidirectional threaded rod 12, the two connecting plates 13 move towards each other, and the car trunk lid is fixed to the mounting assembly with bolts. Then, the drive assembly is rotated, which drives the two connecting plates 13 to move outwards towards each other. The two connecting plates 13 respectively drive the two insert rods 14 to move outwards, so that the insert rods 14 are disengaged from the slots 15. Then, it rotates to the turntable 6. The turntable 6 drives the car trunk lid on the mounting assembly to rotate through the rotating shaft 10 and the connecting bracket 4, so that the car trunk lid is adjusted to a suitable angle. Then, the drive assembly is rotated, which drives the two connecting plates 13 to move inwards towards each other. The two connecting plates 13 respectively drive the two insert rods 14 to move inwards, so that the insert rods 14 are engaged with the slots 15. This realizes the adjustment of the angle of the car trunk lid, which facilitates the painting of the car trunk lid, avoids uneven painting, and greatly improves the quality of painting.

[0022] In this embodiment, the top of the fixed frame 1 is provided with a power component that drives the slide plate 8 to move up and down. The power component includes a self-locking cylinder 7 that is fixed to the top of the fixed frame 1 by bolts. The piston end of the self-locking cylinder 7 passes through the fixed frame 1 and is fixed to the slide plate 8. The height of the slide plate 8 can be adjusted by the self-locking cylinder 7, thereby adjusting the height of the car trunk lid, which greatly facilitates the operation of painting the car trunk lid.

[0023] In this embodiment, mounting components for fixing a car trunk lid are provided on both sides and at the bottom of the connecting frame 4. The mounting components include two connecting shafts 20 fixed to both sides and at the bottom of the connecting frame 4 by bolts. The outer circumference of each of the two connecting shafts 20 is rotatably connected to a second protrusion 18 via bearings. A mounting plate 3 is fixed to one side of each of the two second protrusions 18 by bolts. Two through mounting holes 21 for fixing the car trunk lid are provided on one side of the mounting plate 3. An adjustment component for changing the angle of the mounting plate 3 is provided on the outer circumference of one of the connecting shafts 20. The adjustment component includes components connected to the mounting plate 3 via keys. A worm gear 19 is located on the outer side of the circumference of a connecting shaft 20. The mounting plate 3 is located on one side of the second protrusion 18 and is fixed with two symmetrically arranged first protrusions 16 by bolts. The two first protrusions 16 are rotatably connected by a bearing to a worm 17 that meshes with the worm gear 19. By rotating the worm 17, the worm 17 meshes with the worm gear 19, causing the mounting plate 3 to rotate along the axis of the connecting shaft 20 via the second protrusion 18. This allows for adjustment of the angle of the mounting plate 3, which facilitates painting the car trunk lid installed at the mounting hole 21. The car trunk lid is then installed at the mounting hole 21 by bolts.

[0024] In this embodiment, a slide rail 9 is fixed to one side of the fixed frame 1 by bolts. The slide plate 8 is slidably connected to the slide rail 9. The slide rail 9 improves the stability of the slide plate 8 and avoids the phenomenon of the slide plate 8 deviating during the sliding process.

[0025] In this embodiment, the bottom of the base plate 2 is fixed with multiple self-locking casters by bolts, and the multiple self-locking casters are evenly distributed at the four corners of the base plate 2. The use of multiple self-locking casters in cooperation greatly facilitates the movement of the hanging device and improves the ease of use of the hanging device.

[0026] The use of this utility model involves the following steps:

[0027] S1: First, rotate the worm 17, which meshes with the worm wheel 19, so that the mounting plate 3 rotates along the axis of the connecting shaft 20 through the second protrusion 18, and adjusts the mounting plate 3 to a suitable angle.

[0028] S2: Then use bolts to install the car trunk lid into the mounting hole 21;

[0029] S3: Then rotate the double-threaded rod 12. The double-threaded rod 12 drives the two connecting plates 13 to move outwards in opposite directions. The two connecting plates 13 drive the two insert rods 14 to move outwards respectively, so that the insert rods 14 are disengaged from the slots 15.

[0030] S4: Then turn to turntable 6. Turntable 6 drives the car trunk lid on the mounting assembly to rotate through the rotating shaft 10 and the connecting bracket 4, so that the car trunk lid is adjusted to a suitable angle.

[0031] S5: Finally, rotate the double-threaded rod 12. The double-threaded rod 12 drives the two connecting plates 13 to move inward towards each other. The two connecting plates 13 drive the two insert rods 14 to move inward respectively, so that the insert rods 14 are inserted into the slots 15, thereby adjusting the angle of the car trunk lid.

[0032] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
