Abstract
Description
Technical Field
[0001] This utility model relates to the field of fastener technology, and in particular to a stainless steel non-metallic embedded nut. Background Technology
[0002] Nuts are commonly used fasteners for tightening. When fastening non-metallic materials, the connection strength is relatively low, so embedded nuts are usually required. During later tightening, the nuts are used to ensure the strength of the connection. For some connection positions that require protrusion, spliced nuts are usually used. This method is less efficient and the connection is relatively weak, and the cost of using them in combination is also relatively high. Utility Model Content
[0003] The purpose of this utility model is to provide a stainless steel non-metallic embedded nut, which is manufactured in one piece. When its main structure is embedded in a non-metallic material product, the reinforced combination connecting post and the anti-loosening safety groove can interweave with the material at the mating position during embedding, resulting in better overall embedding firmness and higher mating connection strength during later use. The upper nut body mating seat can be used as a protruding structure to fit the embedding position. In use, it can replace multiple existing components for splicing, resulting in higher connection efficiency and stronger mating firmness at the combined position.
[0004] The technical solution of this utility model is as follows:
[0005] A stainless steel non-metallic embedded nut includes a nut body mating seat with an outer hexagonal shape. The upper center of the nut body mating seat has a main body fastening threaded hole. The nut body mating seat has an integrally formed cylindrical embedded mating connecting post at its lower end. The lower end of the embedded mating connecting post has a central clearance mating groove communicating with the main body fastening threaded hole. The outer cylindrical surface of the embedded mating connecting post has integrally formed and circumferentially evenly distributed reinforcing combined connecting posts. The reinforcing combined connecting posts have outward-opening anti-loosening safety grooves. The lower ends of the reinforcing combined connecting posts and the embedded mating connecting posts are on the same plane. The lower edge of the embedded mating connecting post has a mating guide mating structure.
[0006] Furthermore, the central clearance groove is a cylindrical structure, and the diameter of the central clearance groove is larger than the diameter of the main body fastening connection threaded hole.
[0007] Furthermore, the mating guide structure is a guide fillet or guide chamfer structure.
[0008] Furthermore, both the anti-loosening safety groove and the reinforced combined connecting column have a circular arc-shaped cross-section.
[0009] Furthermore, the length of the anti-loosening safety groove is the same as the length of the embedded connecting post.
[0010] The beneficial effects of this utility model are:
[0011] This utility model is manufactured using a one-piece molding structure. When its main structure is embedded in a non-metallic material product, the reinforced combination connecting column and the anti-loosening safety groove allow for interlocking and fusion with the material at the mating position during embedding, resulting in better overall embedding stability and higher connection strength during later use. The upper nut body mating seat can serve as a protruding structure for mating at the embedding position. During use, it can replace multiple existing components for splicing, resulting in higher connection efficiency and stronger mating stability at the combined position. Attached Figure Description

[0020] like Figures 1 to 7As shown, a stainless steel non-metallic embedded nut includes a nut body mating seat 1 with an outer hexagonal shape. The upper center of the nut body mating seat 1 has a main fastening threaded hole 2, which is the main structure of a conventional nut. The lower end of the nut body mating seat 1 has an integrally formed cylindrical embedded mating connecting post 3, which serves as the embedded structure for non-metallic material products. The lower end of the embedded mating connecting post 3 has a central clearance mating groove 4 communicating with the main fastening threaded hole 2, ensuring greater internal space. The outer cylindrical surface of the embedded mating connecting post 3 has integrally formed and circumferentially distributed reinforced combination connecting posts 5, improving the structural strength of the outer position and providing a staggered mating connection effect when embedded with non-metallic materials, resulting in higher overall embedded mating strength. The reinforced combination connecting post 5 has an outward-opening anti-loosening safety groove 6, which, during embedded mating, can fuse with the material at the embedding position, thereby forming a staggered anti-loosening mating effect and making the overall mating more reliable. The lower ends of the reinforced combined connecting column 5 and the embedded mating connecting column 3 are on the same plane. The lower edge of the embedded mating connecting column 3 is provided with a mating guide mating structure 7, which improves the smoothness of the embedding mating. It is manufactured as a whole with a one-piece molded structure. When its main structure is embedded with non-metallic material products, the reinforced combined connecting column and the mating anti-loosening safety groove can interweave with the material at the mating position during embedding, resulting in better overall embedding firmness and higher mating connection strength in later use. The upper nut body mating seat can be used as a protruding structure for mating at the embedding position. In use, it can replace multiple existing components for splicing, resulting in higher connection efficiency and stronger mating firmness at the combined position.
[0021] Preferably, the central clearance groove 4 is a cylindrical structure, and the diameter of the central clearance groove 4 is larger than the diameter of the main body fastening connection threaded hole 2, so that when the lower end position is engaged, it can effectively clearance the structure at the upper fastening position, resulting in a larger assembly space and better connection stability.
[0022] Preferably, the mating guide structure 7 is a guide rounded corner or guide chamfer structure, which makes the processing operation more convenient during mating and the combination smoother when performing embedded mating.
[0023] Preferably, both the anti-loosening safety groove 6 and the reinforced combined connecting column 5 have arc-shaped cross sections, which makes them easier to manufacture and more efficient.
[0024] Preferably, the length of the anti-loosening safety groove 6 is the same as the length of the embedded connecting post 3, so that the combined strength of the embedded mating position can be further improved and the connection after fusion is more secure.
[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
