Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a convenient and quick-installation rivet nut. Background Technology

[0002] Fasteners are an indispensable component in modern industrial manufacturing and assembly. With the continuous development of industrial technology, the requirements for connection strength, ease of installation, and material adaptability are increasing. Although the traditional bolt and nut combination is widely used in various structural connections, it often has certain limitations in certain specific application scenarios. The original design purpose of rivet nuts is to solve the technical problem of high-strength threaded connections on thin plate materials or soft materials.

[0003] However, existing rivet nuts still have some shortcomings and areas for improvement in practical use. Existing rivet nuts cannot achieve rapid loading and installation when using an air gun. At the same time, existing rivet nuts are prone to failure to tighten due to the inability to apply a large installation torque. Therefore, those skilled in the art have provided a convenient and quick rivet nut installation method to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a convenient and quick installation method for rivet nuts. By setting end caps, positioning during installation is facilitated, solving the problem of not being able to use conventional air guns for quick assembly. At the same time, by using boron steel as the overall material, the overall strength and toughness are improved, avoiding the risk of breakage under high stress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a convenient and quick-installation rivet nut, comprising an end cap, a gear plate fixedly connected to the center of the lower end face of the end cap, a connecting post fixedly connected to the center of the lower end face of the gear plate, a sleeve fixedly connected to the lower end of the connecting post, an upper through hole provided at the center of the upper end face of the end cap, the lower end of the upper through hole penetrating the upper end face of the end cap, the gear plate and the connecting post and extending to the lower end, and a lower through hole provided at the center of the upper end face of the sleeve located inside the upper through hole, the lower end of the lower through hole penetrating the upper end face of the sleeve and extending to the lower end;

[0006] The above technical solution, by setting end caps, facilitates positioning during installation, solving the problem of not being able to use conventional air guns for quick assembly. At the same time, by using boron steel as the overall material, the overall strength and toughness are improved, avoiding the risk of breakage under high stress.

[0007] Furthermore, the connections between the upper and lower ends of the connecting column and the lower end face of the gear plate and the upper end face of the sleeve are respectively rounded.

[0008] The above technical solutions can reduce noise and vibration, resulting in a more uniform stress distribution after installation.

[0009] Furthermore, the end cap, toothed disc, sleeve, and connecting post are all made of boron steel;

[0010] Through the above technical solutions, boron steel has higher strength and hardness than ordinary steel, while also possessing good toughness and wear resistance, ensuring that it is not prone to breakage when subjected to large loads.

[0011] Furthermore, the end cap, toothed disc, sleeve, and connecting post are integrally cast;

[0012] The above technical solutions make the one-piece molded structure more stable.

[0013] Furthermore, the inner wall center of the upper through hole near the upper edge and the inner wall center of the lower through hole near the upper and lower edges are respectively chamfered.

[0014] The above technical solution facilitates installation and avoids jamming or jamming during the loading and installation of the air gun.

[0015] Furthermore, the center of the side wall of the sleeve is chamfered near the upper and lower edges;

[0016] The above technical solution can reduce friction and resistance during installation.

[0017] This utility model has the following beneficial effects:

[0018] 1. By setting an end cap, this utility model facilitates positioning during installation, thus solving the problem of not being able to use a conventional air gun for quick assembly.

[0019] 2. In this utility model, by setting the overall material to boron steel, the overall strength and toughness are improved, avoiding the risk of breakage when subjected to large stress. Attached Figure Description

[0026] 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.

[0027] Reference Figure 1-4 This utility model provides an embodiment of a convenient and quick-installation rivet nut, comprising an end cap 1, a toothed disc 3 fixedly connected to the center of the lower end face of the end cap 1, a connecting post 5 fixedly connected to the center of the lower end face of the toothed disc 3, a sleeve 4 fixedly connected to the lower end of the connecting post 5, an upper through hole 2 provided at the center of the upper end face of the end cap 1, the lower end of the upper through hole 2 penetrating the upper end face of the end cap 1, the toothed disc 3 and the connecting post 5 and extending to the lower end, a lower through hole 6 provided at the center of the upper end face of the sleeve 4 located inside the upper through hole 2, the lower end of the lower through hole 6 penetrating the upper end face of the sleeve 4 and extending to the lower end. By providing the end cap 1, positioning is convenient during installation, solving the problem of not being able to use a conventional air gun for quick assembly. At the same time, by using boron steel as the overall material, the overall strength and toughness are improved, avoiding the risk of breakage under large stress.

[0028] The connection points of the upper and lower ends of the connecting post 5 with the lower end face of the toothed disc 3 and the upper end face of the sleeve 4 are rounded to reduce noise and vibration, resulting in a more uniform stress distribution after installation. The end cap 1, toothed disc 3, sleeve 4, and connecting post 5 are all made of boron steel. Boron steel has higher strength and hardness than ordinary steel, and also has good toughness and wear resistance, ensuring that it is not prone to breakage when subjected to large loads. The end cap 1, toothed disc 3, sleeve 4, and connecting post 5 are integrally cast, which makes the integral structure more stable. The inner wall center of the upper through hole 2 near the upper edge and the inner wall center of the lower through hole 6 near the upper and lower edges are chamfered to facilitate installation and prevent jamming or jamming when loading and installing the air gun. The side wall center of the sleeve 4 near the upper and lower edges is chamfered to reduce friction and resistance during installation.

[0029] Working principle: This utility model is a convenient and quick installation of rivet nuts.
