[0002] Car wheel rim painting is a process of beautifying and protecting the wheel rims by spraying special paint, combining aesthetics and protection.

[0003] Protective devices for automotive wheel rim painting are mainly used to protect the wheel rim from damage during the spraying process and to ensure coating quality. By covering the wheel rim surface, they prevent the paint sprayed directly from the spray gun from corroding or damaging the metal parts. At the same time, they prevent impurities in the spraying environment (such as dust and debris) from mixing into the paint layer, affecting aesthetics and durability. However, when using existing protective devices, they only cover the surface of the automotive wheel rim, and the installation is not very secure. During the painting process, the position is prone to shifting, affecting the protective effect on the screw holes on the surface of the automotive wheel rim. Utility Model Content

[0017] 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.

[0018] Please see Figure 1-5 One embodiment provided by this utility model: A protective device for painting automobile wheel rims includes: The plate body includes a protective cover 1, which is an existing product and is not considered a technical protection point of this application. Therefore, it will not be described in detail here. The fastening mechanism includes a first sealing ring 2, which is fixedly connected to the surface of the protective cover 1 to improve the tightness of the connection between the protective cover 1 and the car wheel hub. A fastening knob 21 is rotatably connected to the surface of the protective cover 1 to drive the adjusting threaded rod 22 to rotate. The adjusting threaded rod 22 is fixedly connected to the surface of the fastening knob 21 to drive the adjusting block 23 to move by its own rotation. The adjusting block 23 is threadedly sleeved on the surface of the adjusting threaded rod 22 to drive the fastening block 25 to move by its own movement. The surface of the adjusting block 23 is hinged. A hinge rod 24 is provided to connect the adjusting block 23 and the fastening block 25. The end of the hinge rod 24 away from the adjusting block 23 is hinged to the fastening block 25, which is used to abut against the inner wall of the car wheel hub, thereby fixing the protective position of the protective cover 1. A limit block 26 is fixedly connected to the surface of the fastening block 25 to limit the movement of the fastening block 25. A connecting groove 27 is provided on the surface of the protective cover 1 for the movement of the fastening block 25. A limit groove 28 is provided on the surface of the connecting groove 27 to limit the movement of the limit block 26 and at the same time provide guidance for the movement of the fastening block 25.

[0019] Furthermore, the adjusting threaded rod 22 is internally rotatably connected to the protective cover 1 via the fastening knob 21, and the adjusting block 23 is internally movably connected to the connecting groove 27 via the adjusting threaded rod 22. Rotating the fastening knob 21 causes the adjusting threaded rod 22 to rotate, thereby causing the adjusting block 23 to move inside the connecting groove 27. The adjusting threaded rod 22 and the adjusting block 23 are self-locking structures and will not rotate without external force.

[0020] Furthermore, the hinge rods 24 are symmetrically distributed in four groups on the surface of the fastening block 25. The hinge rods 24 are rotatably connected to the surface of the fastening block 25 through the adjusting block 23. The hinge rods 24 rotate on the surface of the fastening block 25 as the adjusting block 23 moves.

[0021] Furthermore, the fastening blocks 25 are evenly distributed in four groups on the surface of the adjusting block 23. The fastening blocks 25 are movably connected to the surface of the protective cover 1 through the hinge rod 24. The fastening blocks 25 move on the surface of the protective cover 1 as the hinge rod 24 rotates, thereby abutting against the inner wall of the car wheel hub, thus fixing the protective cover 1 in the protective position on the surface of the car wheel hub.

[0022] Furthermore, the limiting grooves 28 are evenly distributed in four groups on the surface of the connecting groove 27. The limiting block 26 is movably connected to the limiting groove 28 through the fastening block 25. The movement of the fastening block 25 drives the limiting block 26 to move inside the limiting groove 28, thereby limiting the movement position of the limiting block 26 while also providing guidance for the movement of the fastening block 25.

[0023] Furthermore, the replacement mechanism includes a protective insert rod 3, which acts on the surface of the protective cover 1 and is used to insert into the bolt holes of the car wheel hub to protect the bolt holes. A connecting base 31 is fixedly connected to the surface of the protective cover 1 for connecting a limiting buckle 32. A limiting buckle 32 is fixedly connected to the surface of the connecting base 31 for locking onto the mounting groove 34 through its own deformation. A second sealing ring 33 is fixedly connected to the surface of the protective insert rod 3 to improve the sealing performance of the connection between the protective insert rod 3 and the car wheel hub. The surface of the protective insert rod 3 has a mounting groove 34 for mounting on the surface of the connecting base 31.

[0024] Furthermore, the protective rods 3 are evenly distributed in five groups on the surface of the protective cover 1, and the connecting bases 31 are evenly distributed in five groups on the surface of the protective cover 1. The protective rods 3 are connected by the mounting slots 34 and the surface of the connecting bases 31, so that the protective rods 3 are installed on the surface of the protective cover 1 and the connecting bases 31 are inserted into the mounting slots 34.

[0025] Furthermore, the limiting buckles 32 are evenly distributed in four groups on the surface of the connecting base 31. The protective rod 3 is connected by the surface engagement of the mounting slot 34 and the limiting buckle 32. Then, the limiting buckle 32 deforms and engages with the mounting slot 34, thereby fixing the protective rod 3 to the surface of the protective cover 1. The second sealing ring 33 improves the sealing of the connection. Otherwise, the protective rod 3 can be removed and replaced.

[0026] Working principle: When using the protective cover 1, first install the protective rod 3 on the surface of the protective cover 1, so that the connecting base 31 is inserted into the mounting slot 34. Then, the limiting buckle 32 deforms and engages with the mounting slot 34, thereby fixing the protective rod 3 on the surface of the protective cover 1. The second sealing ring 33 improves the sealing of the connection. Conversely, the protective rod 3 can be removed and replaced. Then, turn the fastening knob 21 to drive the adjusting threaded rod 22 to rotate, thereby driving the adjusting block 23 to move inside the connecting groove 27. The hinge rod 24 follows the movement of the adjusting block 23 and rotates on the surface of the fastening block 25. The fastening block 25 follows the rotation of the hinge rod 24 and moves on the surface of the protective cover 1, thereby abutting against the inner wall of the car wheel hub, thereby fixing the protective position of the protective cover 1 on the surface of the car wheel hub. The movement of the fastening block 25 drives the limiting block 26 to move inside the limiting groove 28, thereby limiting the movement position of the limiting block 26 and providing guidance for the movement of the fastening block 25.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
