[0003] In existing technologies, wheel hub anti-theft effects are poor. Because some wheel hubs are attractive or valuable, criminals often remove the connecting bolts on the wheel hubs and steal them directly for their own use or to sell, causing unnecessary losses to car owners. Therefore, there is an urgent need for a wheel hub anti-theft device to solve the risk and problem of wheel hubs being easily stolen. Utility Model Content

[0004] This utility model discloses a wheel hub anti-theft device, which solves the above problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model discloses a wheel hub anti-theft device, including a wheel hub ring and an anti-theft cover. The wheel hub ring has a mounting hole at its center, and multiple connecting holes are opened around the mounting hole. The multiple connecting holes are arranged in a ring array. Connecting bolts are provided inside the connecting holes. The anti-theft cover is engaged with the mounting hole. Multiple covering legs are fixedly connected around the anti-theft cover, and the multiple covering legs cover the outside of the multiple connecting holes respectively.

[0007] The locking mechanism includes a lock body, a lock cylinder, a drive shaft, a fixed block, a rotating block, a bolt, and auxiliary blocks. The lock body is fixedly installed in the center of the anti-theft cover. The lock cylinder is located in the lock body. The drive shaft is connected to the lock cylinder. One side of the rotating block is fixedly connected to the drive shaft. Three bolts are movably provided inside the fixed block. There are three auxiliary blocks, and all three auxiliary blocks are fixedly connected to the anti-theft cover.

[0008] A cover-up and decorative mechanism, which is connected to an anti-theft cover.

[0009] Furthermore, a connecting rod is fixedly connected to one side of the fixed block, and multiple connecting rods are fixedly connected to the lock body. Three straight grooves are equally spaced at the bottom of the fixed block, and the three straight grooves match the three latch rods. A transmission rod is fixedly connected to the bottom of each of the three latch rods, and the transmission rod extends through the straight grooves to the outside of the straight grooves. Three arc-shaped grooves are opened inside the rotating block, and the two ends of the arc-shaped grooves are close to the center and the outer circumference of the rotating block, respectively. The three transmission rods are respectively matched and engaged with the three arc-shaped grooves. Through grooves are opened inside the three auxiliary blocks, and the end of the latch rod away from the fixed block is located in the through groove.

[0010] Furthermore, the connecting rod and the fixing block are fixedly connected by welding, and the connecting rod and the lock body are also fixedly connected by welding.

[0011] Furthermore, the bottom of the anti-theft cover is provided with a plurality of first buckle plates, which are arranged in a circular array at the bottom of the anti-theft cover. Each of the plurality of first buckle plates is engaged with the edge of the opening on the back side of the mounting hole.

[0015] The present invention has the following advantages over the prior art:

[0016] This technical solution incorporates a locking mechanism that allows the anti-theft cover to engage with the mounting hole. After opening the cover, a special key is inserted into the lock cylinder. Turning the key, in conjunction with the lock cylinder and drive shaft, rotates a rotating block. This rotation, along with three arc-shaped grooves, synchronously moves three transmission rods. As these rods move, three locking tongues inside the fixing block extend until they exceed the edge of the opening on the back of the mounting hole. The locking tongues then lock the anti-theft cover securely to the wheel hub by their limiting and blocking action with the mounting hole. Finally, the key can be removed. At this point, the covering legs around the anti-theft cover cover multiple connection holes, preventing unauthorized personnel from directly disassembling the connecting bolts and thus hindering the easy theft of the wheel hub.

Multiple covering legs 6 are fixedly connected around the anti-theft cover 2. The multiple covering legs 6 cover the outside of the multiple connecting holes 4 respectively.

[0030] Locking mechanism 7 includes a lock body 701, a lock cylinder 702, a drive shaft 703, a fixing block 704, a rotating block 705, a latch rod 706, and an auxiliary block 707. The lock body 701 is fixedly installed in the center of the interior of the anti-theft cover 2. The lock cylinder 702 is located in the lock body 701. The drive shaft 703 is connected to the lock cylinder 702. One side of the rotating block 705 is fixedly connected to the drive shaft 703. Three latch rods 706 are movably provided inside the fixing block 704. There are three auxiliary blocks 707, and all three auxiliary blocks 707 are fixedly connected to the anti-theft cover 2. Covering and decorative mechanism 8 is connected to the anti-theft cover 2.

[0031] A connecting rod 708 is fixedly connected to one side of the fixed block 704. Multiple connecting rods 708 are fixedly connected to the lock body 701. Three straight grooves 709 are equally spaced at the bottom of the fixed block 704. The three straight grooves 709 match three latch rods 706. A transmission rod 710 is fixedly connected to the bottom of each of the three latch rods 706. The transmission rod 710 passes through the straight grooves 709 and extends to the outside of the straight grooves 709. Three arc-shaped grooves 711 are formed inside the rotating block 705. The two ends of the arc-shaped grooves 711 are close to the center and the outer circumference of the rotating block 705, respectively. The three transmission rods 710 are matched and engaged with the three arc-shaped grooves 711. Through grooves 712 are formed inside the three auxiliary blocks 707. The end of the latch rod 706 away from the fixed block 704 is located in the through groove 712. The connecting rod 708 is fixedly connected to the fixed block 704 by welding. The connecting rod 708 is also fixedly connected to the lock body 701 by welding.

[0032] The bottom of the anti-theft cover 2 is provided with multiple first buckle plates 9, which are arranged in a ring array at the bottom of the anti-theft cover 2. All the first buckle plates 9 are engaged with the edge of the opening on the back side of the mounting hole 3. The bottom of the cover leg 6 is provided with a groove 10, and the top of the cover leg 6 is provided with a slot 11 communicating with the groove 10. The bottom of the cover leg 6 is fixedly connected with a limiting ring plate 12, which is matched and engaged with the connecting hole 4. The fixing block 704 and the auxiliary block 707 are both provided with multiple reinforcing connecting plates 713 on the side near the center of the anti-theft cover 2.

[0033] In the specific implementation process, the multiple first buckle plates 9 at the bottom of the anti-theft cover 2 can be passed through the interior of the mounting hole 3 and engaged with the edge of the opening on the back side of the mounting hole 3 to initially install the anti-theft cover 2. During this process, the covering legs 6 around the anti-theft cover 2 will cover the multiple connecting holes 4. Then, open the covering and decorative mechanism 8, insert a special key into the lock cylinder 702, and turn the key. This, in conjunction with the lock cylinder 702 and the drive shaft 703, drives the rotating block 705 to rotate. When the rotating block 705 rotates, it can work with the three arc-shaped grooves 711 to synchronously drive the three drive rods 710. When the three transmission rods 710 move, they can cause the three locking tongue rods 706 inside the fixing block 704 to extend until all three locking tongue rods 706 exceed the opening edge on the back side of the mounting hole 3. Then, the anti-theft cover 2 is locked and fixed to the wheel hub 1 by the limiting block between the three locking tongue rods 706 and the mounting hole 3. Finally, the key can be pulled out. At this time, since the covering legs 6 around the anti-theft cover 2 will cover multiple connecting holes 4, and the anti-theft cover 2 cannot be opened and disassembled without the key, it can prevent criminals from directly disassembling the connecting bolts 5, and thus cannot easily steal the wheel hub 1.

[0034] The connection between the connecting rod 708, the fixing block 704, and the lock body 701 is fixed by welding in order to improve the connection strength and stability between the fixing block 704 and the lock, making it less prone to deformation and damage.

[0035] The first buckle plate 9 is used to snap the anti-theft cover 2 to the assembly hole 3, and to initially snap and fix the anti-theft cover 2 to facilitate subsequent locking and fixing operations. The groove 10 and the slot 11 are used to facilitate the subsequent snap and fixation of the decorative cover 801.

[0036] The limiting ring plate 12 is used to ensure that the covering leg 6 can cover the connecting hole 4 when the anti-theft cover 2 is installed, by aligning the limiting ring plate 12 with the connecting hole 4, and to prevent the anti-theft cover 2 from rotating and causing the covering leg 6 to fail to cover the connecting hole 4.

[0037] Among them, the reinforcing connecting plate 713 can improve the stability of the fixing block 704 and the auxiliary block 707 as well as the connection strength between them and the anti-theft cover 2.

[0038] Specific Implementation Example 2: Refer to Figure 1 and Figure 7 In a preferred embodiment, the covering and decoration mechanism 8 includes a decorative cover 801, with multiple decorative legs 802 fixedly connected at equal intervals around the decorative cover 801. A second buckle plate 803 is fixedly connected to the bottom of the decorative legs 802. The second buckle plate 803 matches and engages with the buckle groove 11. The decorative cover 801 is attached to the anti-theft cover 2 and completely covers the lock cylinder 702.

[0039] In the specific implementation process, after the anti-theft cover 2 is installed and locked, the decorative cover 801 can be placed on the surface of the anti-theft cover 2, and multiple second buckle plates 803 can be engaged with the slots 11 on multiple cover legs 6. This allows the decorative cover 801 to cover the lock cylinder 702 on the anti-theft cover 2, making it difficult for criminals to easily discover the existence of the lock cylinder 702 and damage it. In addition, the decorative cover 801 can also improve the overall aesthetics of the device to a certain extent.

[0040] Working principle: In use, the multiple first buckle plates 9 at the bottom of the anti-theft cover 2 can be passed through the interior of the mounting holes 3 and engaged with the edge of the opening on the back side of the mounting holes 3, thus initially installing the anti-theft cover 2. During this process, the covering legs 6 around the anti-theft cover 2 will cover the multiple connecting holes 4. Then, open the covering and decorative mechanism 8, insert a special key into the lock cylinder 702, and turn the key. This, in conjunction with the lock cylinder 702 and the drive shaft 703, drives the rotating block 705 to rotate. When the rotating block 705 rotates, it can work with the three arc-shaped grooves 711 to synchronously drive the three drive rods 710. When the three transmission rods 710 move, they can cause the three locking tongue rods 706 inside the fixing block 704 to extend until all three locking tongue rods 706 exceed the opening edge on the back side of the mounting hole 3. Then, the anti-theft cover 2 is locked and fixed to the wheel hub 1 by the limiting block between the three locking tongue rods 706 and the mounting hole 3. Finally, the key can be pulled out. At this time, since the covering legs 6 around the anti-theft cover 2 will cover multiple connecting holes 4, and the anti-theft cover 2 cannot be opened and disassembled without the key, it can prevent criminals from directly disassembling the connecting bolts 5, and thus cannot easily steal the wheel hub 1.

[0041] After the anti-theft cover 2 is installed and locked, the decorative cover 801 can be placed on the surface of the anti-theft cover 2, and the multiple second buckle plates 803 can be engaged with the slots 11 on the multiple cover legs 6. This allows the decorative cover 801 to cover the lock cylinder 702 on the anti-theft cover 2, making it difficult for criminals to easily discover the existence of the lock cylinder 702 and damage it. In addition, the decorative cover 801 can also improve the overall aesthetics of the device to a certain extent.

[0042] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
