Description

A painting device for automobile repair Technical Field

[0001] This utility model relates to the field of automobile repair, specifically to a painting device for automobile repair. Background Technology

[0002] Automotive repair refers to a series of tasks including inspection, diagnosis, repair, and maintenance of automobiles to ensure their normal operation, safety, and performance. Automotive paint repair is a very important part of automotive repair, mainly used to repair paint damage caused by collisions, scratches, fading, rust, etc., and restore the integrity and aesthetics of the car's appearance.

[0003] To save physical labor for spray painting workers, some existing spray painting equipment is designed in a vertical form. However, the spray nozzles of some existing spray painting equipment cannot be adjusted, resulting in low flexibility of use and significant limitations during spray painting. Furthermore, during the spraying process, the unobstructed spray nozzles cause the sprayed paint to easily spill, which can affect the health of the spray painting workers. Therefore, a spray painting device for automotive repair is proposed to solve the above problems. Summary of the Invention

[0026] 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.

[0027] As shown in Figures 1-4, a car repair painting device includes a base 1, casters 2 at the bottom of the base 1, a handle 3 fixedly connected to the top of the base 1, a paint bucket 4 at the top of the base 1, a support column 5 fixedly connected to the top of the base 1, a lifting device 6 inside the support column 5, a protective box 7 slidably connected to the support column 5 on the outside of the lifting device 6, a rotating device 8 inside the protective box 7, a first connecting block 9 fixedly connected to the outside of the rotating device 8, a connecting pipe 10 connected to the paint bucket 4 via a hose fixedly connected to the outside of the first connecting block 9, a nozzle 11 fixedly connected to the outside of the connecting pipe 10, and a protective cover 12 fixedly connected to the outside of the nozzle 11 via fasteners.

[0028] The lifting device 6 includes a first motor 61 fixedly connected to the outside of the support column 5. The output shaft of the first motor 61 is fixedly connected to a threaded rod 62 rotatably connected to the inside of the support column 5. The outside of the threaded rod 62 is connected to a transmission block 63 fixedly connected to the protective box 7 via a threaded transmission.

[0029] In this embodiment, during actual use, when the first motor 61 is started, the threaded rod 62 inside the support column 5 will rotate. Under the action of the thread, the transmission block 63 will move the protective box 7 up and down along the direction of the thread to adjust and change the position of the protective box 7.

[0030] The support column 5 has two sliding grooves inside, and the protective box 7 has sliders 13 fixedly connected to the front and rear sides of the box, which are respectively slidably connected to the two sliding grooves.

[0031] In this embodiment, during actual use, while the protective box 7 moves, the sliders 13 on both sides of it will also move simultaneously. The direction of the slide groove is parallel to the direction of the threaded rod 62, so that the moving direction of the protective box 7 remains stable.

[0032] The rotating device 8 includes a second motor 81 fixedly connected to the outside of the protective box 7. The output shaft of the second motor 81 is fixedly connected to the outside of a first gear 82 rotatably connected to the inside of the protective box 7. The inside of the protective box 7 is rotatably connected to a connecting shaft 83 fixedly connected to a first connecting block 9. The outside of the connecting shaft 83 is fixedly connected to a second gear 84 that meshes with the first gear 82.

[0033] In this embodiment, during actual use, the start of the second motor 81 will drive the first gear 82 to rotate. The meshing of the first gear 82 and the second gear 84 will cause the connecting shaft 83 inside the second gear 84 to rotate, thereby driving the first connecting block 9 outside the connecting shaft 83 to change its angle.

[0034] The bottom of the protective box 7 is rotatably connected to a fixed shaft 14, and the outside of the fixed shaft 14 is fixedly connected to a second connecting block 15 that is fixedly connected to the connecting pipe 10. The axis of the fixed shaft 14 and the axis of the connecting shaft 83 are located on the same horizontal plane.

[0035] In this embodiment, during actual use, when the connecting pipe 10 rotates through the connecting shaft 83 to change its angle, the second connecting block 15 on the outside of the connecting pipe 10 will also rotate around the fixed shaft 14, and the fixed shaft 14 will support the connecting pipe 10 through the second connecting block 15.

[0036] The protective cover 12 is designed with front and rear parts. A fixing plate 16 is fixedly connected to the outer side of the protective cover 12, and a bolt 17 is threadedly connected to the inside of the fixing plate 16.

[0037] In this embodiment, during actual use, the protective cover 12 is set in half with the central axis as the center, and the fixing plates 16 on each half and the bolts 17 on the outer side of them are tightened and fixed. The bolts 17 can be easily unscrewed to disassemble and clean the protective cover 12, and the cover is reinforced by installing nuts.

[0038] Working principle:

[0039] When painting is required for automotive repair parts, the device can be moved using handle 3 and casters 2. Casters 2 are self-locking casters that can be stopped and fixed stably. The paint bucket 4 is located above the base 1 to prevent the pipe from being stretched too far when the painting position is too far away. The paint bucket 4 uses a pressure pump to spray the paint inside through the nozzle 11. When the first motor 61 is started, the height of the nozzle 11 will change. When the second motor 81 is started, the direction of the nozzle 11 will change, and the protective cover 12 will block the position of the nozzle 11 to prevent paint from escaping and affecting human health.
