Description

Technical Field

[0001] This utility model belongs to the technical field of automotive headlight mounting bolts, specifically relating to an anti-rotation and anti-pull-out automotive headlight mounting bolt. Background Technology

[0002] Automotive headlight mounting bolts are mainly used to fix automotive headlights. There are various types of headlight mounting bolts, including Torx groove pan head machine screws, which can be made of steel, stainless steel, brass, or even nylon. The specifications of headlight mounting bolts vary, and the appropriate bolt specifications and types need to be selected according to the vehicle model and the applicable headlight specifications.

[0003] Currently, automotive headlights are mostly assembled using straight bolts and nuts to mount them onto sheet metal parts. After prolonged use, vibrations can cause gaps to appear between the straight bolts and nuts, leading to rotation and resulting in abnormal noises during the assembly of the headlights, affecting their use. To address this, we propose a new type of anti-rotation and anti-pull-out automotive headlight mounting bolt. Utility Model Content

[0004] The purpose of this invention is to provide an anti-rotation and anti-pull-out automotive headlight mounting bolt to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-rotation and anti-pull-out automotive headlight mounting bolt, comprising a threaded rod segment, one end of which is provided with a fixing plate, the fixing plate being provided with at least three outwardly protruding anti-rotation blocks, and the other end of which is provided with a star-shaped end.

[0006] Preferably, the fixing plate is a circular plate, and the outer diameter of the fixing plate is larger than the outer diameter of the threaded rod segment.

[0007] Preferably, at least three of the anti-rotation blocks are arranged in a ring on the side of the fixing plate away from the threaded rod segment.

[0008] Preferably, at least three of the anti-rotation blocks extend gradually from the inside to the outside on the fixing plate, the at least three anti-rotation blocks do not contact each other, and the at least three anti-rotation blocks form an engagement groove that engages with the connecting threaded block on the automotive sheet metal part.

[0009] Preferably, a guide block is provided between the threaded rod segment and the plum blossom end, and the guide block has a frustum-shaped structure.

[0010] Preferably, the outer diameter of the plum blossom end is smaller than the outer diameter of the threaded rod segment.

[0011] Preferably, the threaded rod segment, the fixing plate, the anti-rotation block, the plum blossom end, and the guide block are an integral structure.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention features a fixing plate at one end of the threaded rod segment, with an outwardly protruding anti-rotation block on the fixing plate. In use, the anti-rotation block on the mounting bolt is first engaged with the connecting threaded block via a locking groove. Then, the threaded rod segment of the mounting bolt is passed through the mounting hole on the automotive sheet metal part. The connecting threaded block is then connected to the automotive sheet metal part by tightening the Phillips head end on the mounting bolt. Next, the mounting hole on the automotive headlight is aligned with the threaded rod segment and inserted. Finally, a nut is screwed in through the Phillips head end and guide block, guiding the threaded rod segment, thus connecting the automotive headlight and the automotive sheet metal part. The fixing plate prevents the mounting bolt from pulling off at the connection point between the headlight and the sheet metal part, improving connection stability. The outwardly protruding anti-rotation block connects with the automotive sheet metal part, preventing the mounting bolt from rotating, enhancing the effective locking performance of the mounting bolt, and further improving the mounting stability of the automotive headlight.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4The anti-rotation and anti-pull-out automotive headlight mounting bolt provided by this utility model includes a threaded rod segment 1. One end of the threaded rod segment 1 is provided with a fixing plate 2, which is a circular plate with an outer diameter larger than that of the threaded rod segment 1. The fixing plate 2 is provided with four outwardly protruding anti-rotation blocks 3, which are arranged in a ring on the side of the fixing plate 2 away from the threaded rod segment 1. The four anti-rotation blocks 3 gradually extend from the inside to the outside on the fixing plate 2. The four anti-rotation blocks 3 do not contact each other, and form an engagement groove 5 between the four anti-rotation blocks 3 to engage with the connecting threaded block on the automotive sheet metal part. The other end of the threaded rod segment 1 is provided with a plum blossom end 4. A guide block 6 is provided between the threaded rod segment 1 and the plum blossom end 4. The guide block 6 is a frustum-shaped structure, and the outer diameter of the plum blossom end 4 is smaller than that of the threaded rod segment 1.

[0021] This utility model has a fixing plate 2 at one end of the threaded rod section 1, and an outwardly protruding anti-rotation block 3 on the fixing plate 2. In use, the anti-rotation block 3 on the mounting bolt is first engaged with the connecting threaded block through the interlocking groove 5. Then, the threaded rod section 1 of the mounting bolt is passed through the mounting hole on the automotive sheet metal part. The connecting threaded block is then connected to the automotive sheet metal part by screwing on the plum-shaped end 4 on the mounting bolt. Next, the mounting hole on the automotive headlight is aligned with the threaded rod section 1 and inserted. Then, the nut is screwed in through the plum-shaped end 4 and the guide block 6, thereby connecting the automotive headlight and the automotive sheet metal part. The fixing plate 2 can prevent the mounting bolt from being pulled off at the connection between the automotive headlight and the sheet metal part, improving the connection stability. The outwardly protruding anti-rotation block 3 can connect with the automotive sheet metal part to prevent the mounting bolt from rotating, improving the effective locking performance of the mounting bolt and further improving the mounting stability of the automotive headlight.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the threaded rod segment 1, the fixing plate 2, the anti-rotation block 3, the plum blossom end 4, and the guide block 6 are integrated into one structure, which improves the structural strength of the bolt.

[0023] In summary, the method of using the anti-rotation and anti-pull-out automotive headlight mounting bolt provided in this embodiment is as follows: First, engage the anti-rotation block 3 on the mounting bolt with the connecting threaded block through the interlocking groove 5. Then, pass the threaded section 1 of the mounting bolt through the mounting hole on the automotive sheet metal part. Next, connect the connecting threaded block to the automotive sheet metal part by tightening the spline end 4 on the mounting bolt. Then, align the mounting hole on the automotive headlight with the threaded section 1 and insert it. Finally, guide the nut into the threaded section 1 through the spline end 4 and guide block 6, thereby connecting the automotive headlight and the automotive sheet metal part.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
