Description

Technical Field

[0001] This utility model relates to the technical field of bolt assembly, and in particular to an anti-theft wheel bolt. Background Technology

[0002] The current mainstream anti-theft approach for wheel bolts is to use non-standard, special polygonal, star-shaped, or columnar irregular grooves at the nut, which are different from general hex wrenches. A special socket is required to remove the bolt. However, existing designs generally ignore the use of common clamping tools such as needle-nose pliers and vise pliers to directly and violently clamp and rotate the bolt head, which makes the anti-theft performance of traditional anti-theft bolts weak. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: an anti-theft wheel bolt, including a bolt body, a driving component and a rotating component. The bolt body is integrally formed with a cylindrical part, an outer ring part and a threaded part. A driving groove is provided on the inner side of the cylindrical part. The driving component is interference-fitted to the bolt body through the driving groove. The driving component is provided with a driving groove for connecting an external sleeve. The rotating component is sleeved on the outer side of the cylindrical part and rotatably connected between the outer ring part and the driving component. The driving component and the rotating component are combined to form a nut part.

[0004] The present invention is further configured such that the outer ring portion is provided with a rotating groove, the rotating component is provided with a protrusion adapted to the rotating groove, and the outer side of the driving component is provided with a stepped surface for abutting against the rotating component.

[0005] The present invention is further configured such that the rotating component has an inner hole, the diameter of which is larger than the outer diameter of the cylindrical part.

[0006] The present invention is further configured such that the driving groove is a polygonal groove, and the driving component is provided with a connecting post adapted to the polygonal groove, the connecting post being interference-connected to the polygonal groove.

[0007] The present invention is further configured such that the height of the connecting column is less than the depth of the polygonal groove.

[0008] The present invention is further configured such that the first drive slot is an internal hexagonal slot.

[0009] The present invention is further configured such that the cross-section of the second drive groove is an internal hexagon, a plum blossom, a star, or other structure with effective clamping or accommodating functions.

[0010] Compared with the prior art, the beneficial effects of this utility model are: After the bolt body is equipped with the driving component and the rotating component, it forms a nut structure similar to that of a traditional cylindrical head screw. When non-specialized tools such as needle-nose pliers or vise pliers are used to clamp the rotating component and attempt to rotate the nut part, the rotating component will spin freely relative to the bolt body. This prevents the rotational torque applied to the rotating component from being effectively transmitted to the bolt body, thus preventing the bolt's threaded portion from being screwed in or out. Only when a special socket tool that matches the driving groove on the driving component is used can the rotation of the bolt body be controlled, thus achieving the anti-theft function.

[0011] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0013] The embodiments of this utility model will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0014] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the intentions or conventions of the user or operator. Therefore, these terms are defined based on the entire contents of this specification.

[0015] like Figure 1-3 As shown, this utility model provides an anti-theft wheel bolt, including a bolt body 1, a driving component 2, and a rotating component 3. The bolt body 1 is integrally formed with a cylindrical part 4, an outer ring part 5, and a threaded part 6. The inner side of the cylindrical part 4 is provided with a driving groove 7. The driving component 2 is interference-fitted to the bolt body 1 through the driving groove 7. The driving component 2 is provided with a driving groove 8 for connecting an external sleeve. The rotating component 3 is sleeved on the outer side of the cylindrical part 4 and rotatably connected between the outer ring part 5 and the driving component 2. The driving component 2 and the rotating component 3 are combined to form a nut part.

[0016] Combination Figure 4 As shown, in this embodiment, the outer ring 5 is provided with a rotating groove 9, the rotating part 3 is provided with a protrusion 10 that is adapted to the rotating groove 9, the outer side of the driving part 2 is provided with a stepped surface 11 for abutting the rotating part 3, the rotating part 3 is provided with an inner hole 12, the diameter R of the inner hole 12 is greater than the outer diameter r of the cylindrical part 4, so that the rotating part 3 is clearance-fitted to the bolt body 1.

[0017] Combination Figure 5 As shown, in this embodiment, the drive groove 7 is a polygonal groove, and the drive component 2 is provided with a connecting post 13 adapted to the polygonal groove. The connecting post 13 is interference-fitted to the polygonal groove. The height h of the connecting post 13 is less than the depth H of the polygonal groove. The drive groove 7 is an internal hexagonal groove, and the connecting post 13 is an external hexagonal post. The distance between opposite sides of the internal hexagonal groove is 13mm with an upper tolerance of -0.05 and a lower tolerance of -0.2. The distance between opposite sides of the external hexagonal post is 13mm with an upper tolerance of +0.15 and a lower tolerance of +0.05, thereby achieving an interference-fit connection between the bolt body 1 and the drive component 2.

[0018] In this embodiment, the cross-section of the drive groove 2 8 is an internal hexagon, a plum blossom, a star, or other structure with effective clamping or accommodating functions. It is worth mentioning that the drive groove 2 8 is designed according to actual needs, and the shape of the drive groove 2 8 can be a non-circular groove such as a triangular groove, a rectangular groove, or an internal hexagonal groove.

[0019] In this invention, after the bolt body 1 is equipped with the driving component 2 and the rotating component 3, they are combined to form a nut structure similar to that of a traditional cylindrical head screw. When a non-specialized tool such as needle-nose pliers or vise pliers is used to clamp the rotating component 3 and attempt to rotate the nut part, the rotating component 3 will spin freely relative to the bolt body 1, so that the rotational torque applied to the rotating component 3 cannot be effectively transmitted to the bolt body 1, thus preventing the bolt thread 6 from being screwed in or out. Only when a special socket tool that matches the driving groove 8 on the driving component 2 is used can the rotation of the bolt body 1 be controlled to achieve the anti-theft function.

[0020] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
