Description

Technical Field

[0001] This utility model relates to the field of rivet nut technology, specifically an anti-torsion rivet nut. Background Technology

[0002] A rivet nut, also known as a riveting nut or self-locking nut, is a fastener used to permanently fix a nut to a sheet metal plate. It uses a riveting process to combine the nut and the sheet metal into a single unit, providing a secure threaded fastening point. Rivet nuts are widely used in various industries such as automotive manufacturing, electronics, electrical engineering, and construction decoration due to their advantages such as strong connection and easy installation.

[0003] When using rivet nuts, they come into direct contact with and are tightly fitted to the sheet metal. Since the sheet metal is made of different materials (including wood, aluminum alloy, etc.), the rivet nuts need to have good torsional resistance to prevent slippage after installation. Therefore, we have improved the above-mentioned existing technology based on actual usage. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-torsion rivet nut includes a nut cap, a rivet nut body, and a deformation post;

[0008] Nut cap, with the rivet nut body connected to the bottom of the nut cap;

[0009] The rivet nut body has an internal thread on its inner wall and deformation columns are evenly arranged vertically on the upper side of its outer wall. A circular groove is opened on the top outer wall of the rivet nut body and is located above the deformation columns.

[0010] The nut cap has multiple sets of limiting grooves evenly distributed on its upper surface, and a circular groove in the shape of a ring is provided at the bottom of the nut cap, with the horizontal groove located inside the limiting groove.

[0011] Furthermore: the nut cap and the rivet nut body are integrally molded structures.

[0012] Furthermore: the limiting groove is a square groove, and the limiting groove is arranged outward from the bottom of the nut cap.

[0013] Furthermore: A rubber ring is fitted onto the inner wall of the transverse circular groove.

[0014] Furthermore: Two rubber rings are fitted onto the inner wall of the vertical circular groove.

[0015] Furthermore: the rivet nut body is mounted on the connecting plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model utilizes a second rubber ring on the rivet nut body and a first rubber ring fitted inside a transverse circular groove. When the rivet nut body deforms, the first and second rubber rings are squeezed and deformed, increasing friction. Combined with the use of the limiting groove, this ensures the stability of the rivet nut body during use, improves its strength, and enhances its torsional resistance.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0031] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0032] Please see Figure 1-6 This utility model provides a technical solution: an anti-torsion rivet nut, which is a fastener used to permanently fix a nut to a plate, including a nut cap 1, a rivet nut body 2 and a deformation post 3;

[0033] Nut cap 1, the bottom of nut cap 1 is connected to rivet nut body 2, the inner wall of rivet nut body 2 is provided with internal thread 4, when screws or tools are drilled into rivet nut body 2, the threaded connection is used to fix it to the plate.

[0034] The rivet nut body 2 has an internal thread 4 on its inner wall and deformation columns 3 are evenly arranged vertically on the upper side of its outer wall. The nut cap 1 and the rivet nut body 2 are integrally formed. The rivet nut body 2 is installed on the connecting plate 10.

[0035] It should be noted that after inserting the rivet nut body 2 into the plate 10, a screw or tool is then inserted into the rivet nut body 2. Rotating the screw or tool will cause the fixing post 10 of the rivet nut body 2 to move upward, thereby causing the deformation post 3 to begin to deform. (Refer to the following text for reference.) Figure 5 At this time, the deformation column 3 and the nut cap 1 will clamp the plate 10, thereby fixing the rivet nut body 2 on the plate 10. The above principle is existing technology and can be directly obtained by those skilled in the art.

[0036] Furthermore, a circular vertical groove 8 is provided on the top outer wall of the rivet nut body 2, and the vertical groove 8 is located above the deformation column 3. A rubber ring 9 is fitted on the inner wall of the vertical groove 8.

[0037] The nut cap 1 has multiple sets of limiting grooves 5 evenly distributed on its upper surface, and the bottom of the nut cap 1 has a circular transverse groove 6. The transverse groove 6 is located inside the limiting groove 5. A rubber ring 7 is fitted on the inner wall of the transverse groove 6. The limiting groove 5 is a square groove, and the limiting groove 5 is arranged outward from the bottom of the nut cap 1.

[0038] Example: When connecting the rivet nut body 2 to the plate 10, insert the rivet nut body 2 into the plate 10, then insert a screw or tool into the rivet nut body 2. Rotating the screw or tool will cause the fixing post 10 of the rivet nut body 2 to move upward, thereby causing the deformation post 3 to deform. At this time, the deformation post 3 and the nut cap 1 will clamp the plate 10. The rubber ring 7 deforms due to the pressure, and the rubber ring 9 also deforms due to compression. Due to the material properties of the rubber rings 7 and 9, the friction between the plate 10 and the rivet nut body 2 is increased. At the same time, the tight fit between the limiting groove 5 and the plate 10 increases the torsional resistance of the rivet nut body 2, thereby fixing the rivet nut body 2 to the plate 10. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 This ensures the stability of the rivet nut body 2 during use and improves the strength of the rivet nut body 2.

[0039] It should be noted that the electrical components of this utility model have already combed the wire harness during operation, so there will be no problem of wire harness tangling.

[0040] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
