[0002] When installing automotive parts, fasteners are used to connect and secure adjacent parts in order to ensure a firm fit between them.

[0003] Existing automotive bolt fasteners mainly consist of a hexagonal swivel, a washer mounted on one side of the hexagonal swivel, a stud mounted on the hexagonal swivel and passing through the washer, and a hexagonal nut mounted on the stud. When connecting and fixing automotive parts, the stud passes directly through the two parts to be connected, and then the hexagonal nut is screwed onto the stud, thereby achieving a reliable connection between two adjacent automotive parts.

[0004] While existing automotive fasteners can connect adjacent automotive parts, they suffer from several drawbacks. Firstly, when screwing the hexagonal nut onto the free end of the stud, inconsistent initial tightening force can cause the nut to become misaligned, making the tightening process cumbersome and inefficient. This hinders the rapid connection of adjacent automotive parts. Secondly, when using pliers in confined spaces, the small contact area between the hexagonal wrench and the nut's surface and the pliers can lead to slippage and misalignment, further impeding efficient tightening and installation of the automotive bolt fastener.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] like Figures 1-3 As shown, an easy-to-install automotive fastener in this embodiment includes a hexagonal swivel head 1. A washer 9 is mounted on one side of the hexagonal swivel head 1. A stud 8 is mounted on the hexagonal swivel head 1 at the center of the washer 9. The end of the stud 8 away from the hexagonal swivel head 1 has three guide grooves 7 arranged in a ring. A hexagonal nut 4 is provided on one side of the stud 8. A screw hole 3 is provided in the center of the hexagonal nut 4. A washer 5 is mounted on the side of the hexagonal nut 4 facing the stud 8. A guide ring 6 is provided on the side of the washer 5 facing away from the hexagonal nut 4. Three guide platforms 10 are installed in a ring inside the guide ring 6. Anti-slip toothed grooves 2 are installed on the outer sides of both the hexagonal swivel head 1 and the hexagonal nut 4. The guide ring 6 faces the outer wall of the hexagonal nut 4. A turntable 11 is installed, and a groove 12 is provided on the washer 2 5 that mates with the turntable 11. When the hexagonal nut 4 is screwed in, the guide table 10 and the guide ring 6 work together to ensure that the hexagonal nut 4 does not become skewed during the screwing process, which facilitates the quick locking of the free end of the stud 8. This makes the installation efficiency between two adjacent automotive parts higher. The anti-slip groove 2 fits with the teeth of the chuck on the external pliers, which can effectively increase the contact area between the hexagonal head 1 and the hexagonal nut 4 and the external pliers. This prevents the hexagonal head 1 and the hexagonal nut 4 from sliding and misaligning relative to the external pliers when tightening with pliers in a narrow space, so that the fastener can be installed quickly.

[0025] like Figures 1-3As shown, in this embodiment, both gasket 1 9 and gasket 2 5 are made of stainless steel. Gasket 1 9 is welded to the hexagonal swivel 1. The stud 8 passes through gasket 1 9 and is welded to the hexagonal swivel 1. Gasket 1 9 can effectively increase the friction between the stud 8 and the hexagonal swivel 1 and the automotive parts after locking. Gasket 2 5 is mainly used to provide an installation base for the guide ring 6.

[0026] like Figures 1-3 As shown, in this embodiment, the guide table 10 and the guide groove 7 are slidably fitted. The inner diameter of the guide ring 6 is larger than the diameter of the screw hole 3, which can ensure that the stud 8 passes smoothly through the guide ring 6, thereby facilitating the convenient screwing of the hexagonal nut 4 onto the stud 8. The turntable 11 is welded to the guide ring 6. The side cross section of the turntable 11 is an inverted T-shaped structure. The turntable 11 and the turn groove 12 are rotatably fitted. The fit between the turntable 11 and the turn groove 12 can realize the convenient rotation between the hexagonal nut 4 and the guide ring 6, so that the hexagonal nut 4 can be conveniently screwed onto the stud 8 for locking while the guide ring 6 moves along the guide groove 7. The screw hole 3 passes through the washer 2 5 and the hexagonal nut 4. The size of the screw hole 3 matches the size of the threaded part on the stud 8. The anti-slip groove 2 is formed on the hexagonal turn head 1 and the hexagonal nut 4.

[0027] The specific implementation process of this embodiment is as follows: When in use, the stud 8 is first passed between the two automotive parts to be connected, and then the guide plate 10 is inserted into the guide groove 7. At the same time, the hexagonal nut 4 is rotated under the action of an external tool so that the free end of the stud 8 is locked under the action of the hexagonal nut 4, thereby realizing the quick connection and fixation between the two adjacent automotive parts. When this type of automotive fastener is used, not only can the hexagonal nut 4 not be skewed during the tightening process under the action of the guide plate 10 and the guide ring 6, which facilitates the quick locking of the free end of the stud 8, thus making the installation efficiency between the two adjacent automotive parts higher, but also by providing anti-slip tooth grooves 2 on the outside of the hexagonal swivel head 1 and the hexagonal nut 4, the contact area between the anti-slip tooth groove 2 and the external pliers can be effectively increased, thereby avoiding the sliding misalignment between the hexagonal swivel head 1 and the hexagonal nut 4 relative to the external pliers when tightening with pliers in a narrow space, so that the fastener can be installed quickly.

[0028] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
