Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of screws, and in particular, to an anti-slip fastening screw. Background Art

[0002] In industrial production and daily life, screw fasteners, as a common connecting component, are widely used in the manufacture of various equipment. Therefore, the fixing performance of screws directly affects the safety and reliability of equipment use.

[0003] Currently, traditional screws are prone to sliding under the influence of external vibrations and other factors during use. Once the screw slides off, it will have a great impact on the normal and safe use of the equipment. For the above reasons, the present utility model proposes an anti-slip fastening screw. Summary of the Utility Model

[0004] In view of the above problems, the embodiments of the present application provide an anti-slip fastening screw to solve the problem of easy sliding of traditional screws.

[0005] The embodiments of the present application provide an anti-slip fastening screw, including a screw head. The center of the bottom surface of the screw head is fixedly connected with a screw rod. A side groove is opened on the side wall of the screw rod, and a top groove is opened on the top surface of the screw head. The side groove communicates with the top groove. A top block is inserted into the top groove, and a positioning plate is fixedly connected to the bottom surface of the top block. The positioning plate is inserted into the side groove.

[0006] In some embodiments, a first positioning hole is opened on the side wall of the inner cavity of the side groove where the top block is located, and a second positioning hole is opened on the side wall of the side groove. The first positioning hole and the second positioning hole are concentrically arranged and penetrated by the same positioning rod.

[0007] In some embodiments, both ends of the positioning rod extend out of the side wall of the screw head, and both ends of the positioning rod are bent.

[0008] In some embodiments, the top surface of the top block extends out of the top surface of the screw head. A first through hole is opened on the top block, and a groove is opened on the side wall of the top block.

[0009] In some embodiments, the cross section of the positioning plate is diamond-shaped, and the side wall of the side groove and the positioning plate are mutually matched.

[0010] In some embodiments, a plurality of anti-slip lines are opened on the bottom surface of the screw head.

[0011] Through the above solution, by inserting the positioning plate into the side groove, the side wall of the positioning plate is inserted into the inner side wall of the threaded hole, realizing the positioning and installation of the screw rod in the threaded hole. And because both sides of the positioning plate are respectively positioned in the side groove and the threaded hole, the rotation of the screw rod can be effectively avoided, thus realizing the anti-slip function of the screw and improving the fastening property of the bolt. Through the setting of the anti-slip lines, the stability of the screw installation can be further improved, and the use effect is good.
