[0002] With the development of economy, there are more and more styles of car wheels. In order to show individuality, spraying color is also the most common way to improve beauty. The requirement for wheel color matching is that one color on the same wheel has a clear boundary with another color, and the colors cannot penetrate each other.

[0003] According to patent No. CN202320684924.2, a wheel hub color processing protection device is disclosed, including a straight rod, the outer side of the straight rod is provided with an external thread, the lower part of the straight rod is provided with a wheel hub positioning assembly, the upper part of the straight rod is provided with a color protection assembly, the wheel hub positioning assembly includes a ring body, the ring body is movably sleeved on the outer side of the straight rod, four connecting rods are hinged at the bottom of the ring body, and a clamping block is ball-connected at one end of the connecting rod away from the ring body.

[0004] The above scheme still has certain technical defects in actual use. Since the straight rod needs to be put inside the wheel hub, the workers need to lift the entire device and insert it from the top of the wheel hub. Since the device is large and heavy, it is very troublesome to operate, which will greatly reduce the processing efficiency of the wheel hub. Moreover, the size of the protective cover cannot be replaced according to the size of the wheel hub. For this reason, we propose a wheel hub processing protection device. Utility Model Content

A through groove 6 is provided on the outer periphery of the sleeve 3. One side of the movable connecting seat 9 extends to the outside through the through groove. A positioning block 10 is fixedly installed on the outer end of the movable connecting seat 9. The width of the through groove 6 is greater than the width of the upper push rod 7 and the lower push rod 8. An internal thread is provided on the inner top end of the sleeve 3. A screw 12 is spirally connected to the inner top end of the sleeve 3. A protective cover 13 is clamped on the top end of the screw 12.

[0022] Specifically, a slot 20 is provided on the top surface of the screw rod 12, a card slot 21 is provided on one side of the inner bottom end of the slot 20, a toggle rod 16 is slidably connected to the bottom of the protective cover 13, a card block 19 is fixedly installed at the bottom of the toggle rod 16, the toggle rod 16 is inserted into the interior of the slot 20 and fixedly engaged with the card slot 21 through the card block 19.

[0023] Specifically, a lifting spring 5 is provided inside the sleeve 3 , and two ends of the lifting spring 5 are fixedly connected to the bottom surface of the sleeve 3 and the bottom of the columnar pressing block 4 respectively.

[0024] Specifically, a handle 14 is fixedly installed on the top of the protective cover 13, and sliding grooves 15 are opened on both sides of the bottom of the protective cover 13. The sliding groove 15 passes through the inner side of the handle 14. The toggle rod 16 extends to the inside of the handle 14 and is slidably connected to its inner wall. A connecting block 17 is slidably connected to the inner wall of one side of the sliding groove 15, and the connecting block 17 is fixedly connected to the toggle rod 16.

[0025] Specifically, a clamping spring 18 is provided at one end of the connecting block 17 extending to the inner wall of the sliding groove 15 , and two ends of the clamping spring 18 are fixedly connected to the connecting block 17 and the protective cover 13 respectively.

[0026] Specifically, a receiving groove 11 is opened in the middle of the through groove 6 , and the size of the receiving groove 11 is larger than the size of the positioning block 10 .

[0027] Specifically, a buffer pad 2 is provided on the top of the bottom plate 1 , and the buffer pad 2 is fixedly connected to the bottom plate 1 by gluing.

[0028] In the present embodiment, when in use, the handle 14 is rotated to remove the screw rod 12 and the protective cover 13, and then the wheel hub is placed on the bottom plate 1, and the middle through hole thereof passes through the sleeve 3, and a certain buffering effect is played by the buffer pad 2, and then the screw rod 12 is inserted into the sleeve 3, and the two are spirally connected through the internal thread thereof, and then the handle 14 is rotated in the opposite direction to make it move downward continuously. During the downward movement of the screw rod 12, the columnar pressing block 4 is squeezed to move toward the bottom end of the sleeve 3, and the lifting spring 5 and the upper push rod 7 are compressed at the same time. Since the upper push rod 7 is movably connected with the lower push rod 8 and the columnar pressing block 4, and the lower push rod 8 is movably connected with the bottom end of the sleeve 3, during the downward movement of the columnar pressing block 4, the upper push rod 7 and the lower push rod 8 are movably connected.
