Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, and more particularly to a fastener for an automobile headlight and the automobile headlight. Background Art

[0002] Fasteners generally consist of bolts and nuts, which are used in a variety of applications, including automotive parts assembly, electronic component assembly, furniture assembly, and construction site structure assembly. Their primary function is to connect and secure two objects. However, ordinary nuts can become loose due to vibrations or external impacts caused by driving, which can lead to the nut falling off over time, potentially causing safety hazards. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a fastener for an automobile headlight and an automobile headlight, which have the advantages of being fixed and stable.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fastener for a car headlight and a car headlight, comprising a nut, a circular groove being provided in the middle of the inner cavity of the nut, a threaded hole being provided at the upper end of the circular groove, and a screw being engaged in the inner cavity of the threaded hole.

[0005] As an optimal technical solution of the present invention, the front end of the nut is fixedly installed with closed ring one, closed ring two and closed ring three, and the front end of the nut is fixedly installed with three pads, which are distributed at equal angles around the axis of the nut.

[0006] As a preferred technical solution of the present invention, the threaded hole passes through the side wall of the nut, the length of the screw stud is greater than the depth of the threaded hole, and the closed ring 1 and the closed ring 2 are both annular.

[0007] As a preferred technical solution of the present invention, a bolt is fixedly installed at the rear end of the headlight, the rear end of the bolt is embedded in a nut, and the baffle is fixed by the nut and the bolt installed at the rear end of the headlight.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0009] 1. The utility model first passes the bolt through the headlight and the baffle, then aligns the threaded hole of the nut with the bolt and inserts it, rotates the nut until it is fixed, then inserts the screw into the threaded hole and tightens the screw. While tightening the screw, the bottom end of the screw will clamp the bolt downward until the bolt cannot be turned, thereby achieving the effect of preventing the nut from falling off.

[0010] 2. In the present invention, when the nut is tightened, the closed rings 1, 2 and 3 fixed at the front end of the nut will contact the baffle. As the nut is tightened, the closed rings 1, 2 and 3 at the front end of the nut will be squeezed tighter until they are fixed, thereby achieving a sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 5 As shown, the utility model provides a fastener for an automobile headlight and an automobile headlight, comprising a nut 4, a circular groove 5 is formed in the middle of the inner cavity of the nut 4, a threaded hole 6 is formed at the upper end of the circular groove 5, and a screw 7 is engaged in the inner cavity of the threaded hole 6.

[0019] First, insert the bolt 3 through the headlight 1 and the baffle 2, then align the threaded hole of the nut 4 with the bolt 3 and insert it. Turn the nut 4 until it is fixed. Then insert the screw 7 into the threaded hole 6 and tighten the screw 7. While tightening the screw 7, the bottom end of the screw 7 will clamp the bolt 3 downward until the bolt 3 cannot be turned anymore, thereby achieving the effect of preventing the nut 4 from falling off.

[0020] Among them, the front end of the nut 4 is fixedly installed with a closed ring 1 8, a closed ring 2 9 and a closed ring 3 10, and the front end of the nut 4 is fixedly installed with three pads 11, which are distributed at equal angles around the axis of the nut 4.

[0021] By tightening the nut 4, the closed ring 1 8, the closed ring 2 9 and the closed ring 3 10 fixed at the front end of the nut 4 will contact the baffle 2. As the nut 4 is tightened, the closed ring 1 8, the closed ring 2 9 and the closed ring 3 10 at the front end of the nut 4 will be squeezed tighter until they are fixed, thereby achieving a sealing effect.

[0022] The threaded hole 6 passes through the side wall of the nut 4 , the length of the screw 7 stud is greater than the depth of the threaded hole 6 , and the closed ring 1 8 and the closed ring 2 9 are both annular.

[0023] The nut 4 can be better fixed by the length of the screw 7 being greater than the depth of the threaded hole 6. The closed ring 1 8 and the closed ring 2 9 are both annular, which can achieve a better sealing effect.

[0024] The rear end of the headlight 1 is fixedly mounted with a bolt 3 , the rear end of the bolt 3 is engaged in a nut 4 , and the baffle 2 is fixed by the nut 4 and the bolt 3 mounted on the rear end of the headlight 1 .

[0025] The bolt 3 passing through the rear end of the headlight 1 is embedded in the nut 4 in order to fix the baffle 2.

[0026] The working principle and usage process of the present invention are as follows: when fixing, first pass the baffle 2 fixed at the rear end of the headlight 1 through the hole on the bolt 3, then align the threaded hole on the nut 4 with the bolt 3 and insert it, and then turn the nut 4. While turning the nut 4, the closed ring 1 8, closed ring 2 9 and closed ring 3 10 fixed at the front end of the nut 4 will slowly contact the baffle 2. As the nut 4 is tightened more and more, the closed ring 1 8, closed ring 2 9 and closed ring 3 10 at the front end of the nut 4 will be squeezed more and more closed until it is fixed. Then insert the screw 7 into the threaded hole 6 and then tighten the screw 7. While tightening the screw 7, the bottom end of the screw 7 will slowly move downward along the circular groove 5 opened in the inner cavity of the nut 4 and slowly clamp the bolt 3 until the bolt 3 cannot be turned anymore.
