Description

Technical Field

[0001] The utility model relates to the technical field of scooter parts, in particular to an anti-loosening positioning screw. Background Art

[0002] Scooter positioning screws are key mechanical components used to secure and adjust scooter components, playing a vital role in scooter construction. These screws are commonly used to connect and secure different parts of a scooter, ensuring stability and safety. They are designed with wear resistance in mind to ensure long-term reliability and durability. In practical application, current positioning screws are first created by creating corresponding guide holes in two objects. The positioning screws are then inserted into these holes. The portion of the positioning screw that protrudes from the object is threaded, and a nut is threaded to secure the positioning screw.

[0003] Based on the above, the inventors have discovered the following problem: after the existing positioning screw positions and fixes two objects, during the use of the scooter, the vibration and impact between the two objects will affect the positioning screw, causing the positioning screw to loosen or wear, thereby affecting the overall operation of the scooter.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-loosening positioning screw is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-loosening positioning screw to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] A loose-proof positioning screw comprises a positioning screw body and an anti-loosening mechanism, wherein the positioning screw body comprises a screw head, a rod body is connected to the center of one end of the screw head, a connecting portion is connected to the end of the rod body away from the screw head, a bolt is connected to the end of the connecting portion away from the rod body, and the anti-loosening mechanism comprises a gasket, which is sleeved on the outside of the rod body, and a shock-absorbing spring is connected to one side of the gasket, and the end of the shock-absorbing spring away from the gasket is connected to the screw head.

[0008] Furthermore, the gasket is stepped, and the diameter of the gasket end close to the screw head is smaller than the diameter of the gasket end away from the screw head, and the outer wall of the gasket end close to the screw head fits with the inner wall of the shock-absorbing spring end away from the screw head.

[0009] The beneficial effect of adopting the above further scheme is that by setting the gasket into a step shape, the diameter of one end of the gasket is smaller than the diameter of the other end, and the outer wall of the end with the smaller diameter of the gasket fits with the inner wall of one end of the shock absorber spring, thereby increasing the contact area between the gasket and the shock absorber spring.

[0010] Furthermore, a circular hole is opened at the center of the gasket, and the inner wall of the circular hole is loosely matched with the outer wall of the rod body.

[0011] The beneficial effect of adopting the above further solution is that by providing a circular hole, the inner wall of the circular hole and the outer wall of the rod body are loosely matched, thereby facilitating the gasket to slide on the rod body.

[0012] Furthermore, a center hole is formed at one end of the screw head away from the shock-absorbing spring, and the center hole is in the shape of a regular hexagon.

[0013] The beneficial effect of adopting the above further solution is that by providing a center hole that is in the shape of a regular hexagon, it is convenient for the user to operate it through a special hexagonal tool such as a hexagonal wrench, which can provide better torque transmission to the positioning screw body.

[0014] Furthermore, the connecting portion is stepped, and the bottom diameter of the connecting portion is larger than the outer diameter of the bolt. The beneficial effect of adopting the above further solution is that by providing the connecting portion, and the bottom diameter of the connecting portion is larger than the outer diameter of the bolt, the bolt is limited.

[0015] Furthermore, the screw head, rod body, connecting part and bolt are all made of metal, and the surfaces of the screw head, rod body, connecting part and bolt are coated with an anti-rust coating.

[0016] The beneficial effect of adopting the above further solution is that by setting the screw head, rod body, connecting part and bolt to metal materials and coating them with anti-rust coating, the service life and corrosion resistance of the screw head, rod body, connecting part and bolt are improved.

[0017] Compared with the prior art, the beneficial effect of the present invention is that when the anti-loosening positioning screw body is installed in a pair of threaded holes of a fixed object, if the positioning screw body is subjected to long-term vibration, the combination of the bolt and thread on the positioning screw body may loosen or even fall off. By arranging a gasket and a shock-absorbing spring on the rod body, after the bolt and the threaded hole are fixed, the shock-absorbing spring will generate an extrusion buffer between the positioning screw body and the fixed object, and under the action of the elastic force of the intermediate gasket and the shock-absorbing spring, the possibility of the positioning screw body loosening and falling off is reduced. At the same time, the shock-absorbing spring can play a shock-absorbing and buffering role, absorb vibration and impact force, thereby extending the service life of the positioning screw body.
