Description

Technical Field

[0001] The utility model relates to the technical field of bolt fasteners, in particular to an automotive bolt fastener. Background Art

[0002] After long-term use of automotive bolt fasteners, the threaded fasteners are prone to loosening, resulting in gaps between the bolts and the buckle caps. Since automobiles are used outdoors, grease and dust are likely to enter the fasteners, causing the internal structure of the fasteners to be corroded by foreign objects and accelerating the aging and corrosion of the fasteners.

[0003] Therefore, it is necessary to improve the traditional automotive bolt fasteners to avoid the above-mentioned problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automotive bolt fastener to solve the above problems.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An automotive bolt fastener includes a screw rod, a fixed disk is fixed on the screw rod, and a screw head is fixed on the top of the fixed disk. A collar is threadedly connected to the fixed disk, and the bottom of the collar and the fixed disk are in contact with the corresponding part of the vehicle together. A rotating sleeve is rotatably connected to the collar, and a sleeve groove adapted to the screw head is formed on the rotating sleeve. A fitting is provided on the collar to cooperate with the fixed disk.

[0007] Preferably, the fitting includes a slot formed at the bottom of the collar, a gasket is slidably connected at the slot, a convex block is fixed on the outer wall of the collar, a vertical hole is formed on the convex block, and a vertical rod is slidably connected to the vertical hole formed on the collar.

[0008] Preferably, a groove connected to the vertical hole is formed on the collar, a spring is sleeved on the vertical rod, and the spring is located at the groove.

[0009] Preferably, the bottom of the gasket is made of rubber material.

[0010] Preferably, one end of the spring abuts against the gasket, and the other end abuts against the inner wall of the groove.

[0011] In summary, due to the adoption of the above technical scheme, the beneficial effects of the utility model are:

[0012] 1. In the present application, under the elastic force of the spring, the spring pushes the gasket to move, so that the gasket and the fixed disk are in contact with the corresponding part of the vehicle together. When the bolt becomes loose, the gasket can still be in contact with the corresponding part of the vehicle under the action of the elastic force, preventing substances such as dust from entering the part where the screw rod is threadedly connected to the vehicle, and effectively preventing substances such as dust from affecting the bolt.

[0013] 2. In the present application, under the protection of the rotating sleeve, it can play a role in shielding and protecting the connection between the fixed disk and the collar, preventing substances such as dust from entering the connection between the fixed disk and the collar. Therefore, it effectively avoids the direct exposure of the bolt head to the environment and further being corroded and damaged in the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment

[0021] The present invention provides a technical solution. Please refer to Figures 1-4 :

[0022] An automobile bolt fastener includes a screw rod 1, a fixing plate 2 is fixed on the screw rod 1, a screw head 3 is fixed on the top of the fixing plate 2, a collar 4 is connected to the fixing plate 2 through threads, and the bottom of the collar 4 and the fixing plate 2 are in contact with the corresponding part of the automobile, a rotating sleeve 5 is rotatably connected to the collar 4, and a sleeve groove 6 matching the screw head 3 is provided on the rotating sleeve 5, and a matching piece matching the fixing plate 2 is provided on the collar 4. After the collar 4 is connected to the fixing plate 2 through threads, it can shield the part where the screw rod 1 is connected to the corresponding part of the automobile through threads, and prevent dust and other substances from entering the part where the screw rod 1 is connected to the corresponding part of the automobile through threads. Example

[0023] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the matching part includes a slot 7 formed at the bottom of the collar 4, and a gasket 11 is slidably connected to the slot 7, the bottom of the gasket 11 is made of rubber material, a protrusion 8 is fixed on the outer wall of the collar 4, and a vertical hole 9 is formed on the protrusion 8, and a vertical rod 12 is formed on the collar 4 and slidably connected to the vertical hole 9. Under the action of the gasket 11, the screw rod 1 and the corresponding part of the car can be partially shielded by the threaded connection.

[0024] The collar 4 is provided with a groove 10 connected to the vertical hole 9, and the vertical rod 12 is provided with a spring 13, and the spring 13 is located at the groove 10. One end of the spring 13 abuts against the gasket 11, and the other end abuts against the inner wall of the groove 10. Under the action of the spring 13, even if the bolt shakes or moves, the gasket 11 can still stably abut against the corresponding part of the car, preventing dust and other substances from entering the part where the screw rod 1 is threadedly connected to the car.

[0025] In summary, after the screw rod 1 provided in this embodiment is connected to the automobile, the sleeve groove 6 of the rotating sleeve 55 can be aligned with the screw head 3. The sleeve ring 4 is rotated so that the sleeve ring 4 is connected to the fixed plate 2 through threads until the sleeve groove 6 is sleeved on the screw head 3, and the bottom of the sleeve ring 4 and the fixed plate 2 are in contact with the corresponding part of the automobile.

[0026] Under the elastic force of the spring 13, the spring 13 pushes the gasket 11 to move, so that the gasket 11 abuts against the corresponding part of the car. Even if the bolt is loose, the gasket 11 can still abut against the corresponding part of the car under the elastic force of the spring 13. Therefore, the gasket 11 can still stably abut against the corresponding part of the car, preventing dust and other substances from entering the part where the screw rod 1 is connected to the car thread, effectively preventing dust and other substances from affecting the bolt.

[0027] The foregoing description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
