Description

Technical Field

[0001] The utility model relates to the technical field of self - tapping screw sleeves, and specifically relates to a self - tapping screw sleeve with a built - in tapping function. Background Technique

[0002] A wire screw insert is a new type of internal thread fastener, suitable for threaded connections. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread, and then a bolt (or screw) is screwed into it. Also known as a threaded insert, simply called an insert, it is a spring - shaped concentric body of internal and external threads precisely processed from high - strength, high - precision, and smooth - surfaced cold - rolled diamond - shaped stainless steel wire. It is mainly used to strengthen and protect the internal threads of low - strength materials. Its principle is to form an elastic connection between the screw and the internal thread in the base body, eliminate thread manufacturing errors, and improve the connection strength.

[0003] However, during the process of using a self - tapping screw sleeve, we usually need to screw it into a threaded hole. However, in the actual installation process, this step often requires the assistance of special tools. Without these special tools, it will be very difficult to screw the screw sleeve into the internal threaded hole. This situation not only is not conducive to the flexible use of the screw sleeve but also is not conducive to the rapid installation of the screw sleeve, thus affecting the efficiency of the entire installation process.

[0004] Therefore, a self - tapping screw sleeve with a built - in tapping function is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self - tapping screw sleeve with a built - in tapping function to solve the problems raised in the above - mentioned background technique.

[0010] An installation mechanism is arranged above the screw sleeve body and is used to conveniently adjust the rotation and installation of the screw sleeve body. The installation mechanism includes an installation block arranged above the screw sleeve body, and a through - hole is penetrated through the top surface of the installation block;

[0011] A limiting mechanism is arranged below the installation block and is used to limit and fix the installation block. The limiting mechanism includes two limiting columns arranged below the installation block.

[0012] Preferably, a hexagonal groove is formed in the top surface of the mounting block, and a plurality of grooves are formed through the top surface of the mounting block.

[0013] Preferably, a plurality of first threaded grooves are formed in the top surface of the screw sleeve body, and the plurality of grooves on the mounting block are respectively threadedly connected with the inner walls of the plurality of first threaded grooves through a plurality of bolts.

[0014] Preferably, two second threaded grooves are formed in the top surface of the screw sleeve body, fixing threads are formed on the outer walls of the lower ends of the two limiting columns, the outer walls of the lower ends of the two limiting columns are respectively threadedly connected with the inner walls of the two second threaded grooves, and the upper ends of the two limiting columns are arranged in a hemispherical shape.

[0015] Preferably, two clamping grooves are respectively formed in the outer walls of the two limiting columns, two limiting grooves are formed in the bottom surface of the mounting block, and the outer walls of the two limiting columns are respectively slidably connected with the inner walls of the two limiting grooves.

[0016] Preferably, a plurality of adjusting grooves are arranged inside the mounting block, a plurality of moving plates are respectively slidably connected to the inner walls of the plurality of adjusting grooves, a plurality of springs are respectively fixedly installed on the sides of the plurality of moving plates, and the other ends of the plurality of springs are respectively fixedly connected with the inner walls of the plurality of adjusting grooves.

[0017] Preferably, a plurality of clamping columns are respectively fixedly installed on the sides of the plurality of moving plates, the other ends of the plurality of clamping columns respectively slide through the inner walls of the plurality of adjusting grooves and extend into the limiting grooves, and one ends of the plurality of clamping columns are respectively clamped with the plurality of clamping grooves.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] Through the cooperation of the second threaded groove and the limiting column, the limiting column can be conveniently installed and fixed. When the mounting block moves downward, the limiting groove is aligned with the limiting column, so that the limiting column cooperates with the limiting groove. When the limiting column moves into the limiting groove, the limiting column pushes the clamping column to drive the moving plate to move and compress the spring. When the limiting column moves to the innermost part of the limiting groove, the spring pushes the moving plate and the clamping column to move, and the clamping column moves into the clamping groove to fix the limiting column, so that the limiting column is not easily removed from the limiting groove, ensuring that the mounting block is not easily offset, and improving the efficiency and quality of subsequent fixing.

A limiting mechanism 3 is arranged below the installation block 201 for limiting and fixing the installation block 201. The limiting mechanism 3 includes two limiting columns 302 arranged below the installation block 201.

[0034] In this embodiment: Through the installation mechanism 2, the screw sleeve body 1 can be installed and fixed, and it is convenient to remove the installation block 201 from the screw sleeve body 1. Through the setting of the limiting mechanism 3, the installation block 201 and the screw sleeve body 1 can be preliminarily limited and fixed, so that the installation block 201 can quickly align the position, and the efficiency is relatively high.

[0035] Specifically, as Figures 1-4 shown, a hexagonal groove 202 is opened on the top surface of the installation block 201, and a plurality of grooves 203 are penetrated through the top surface of the installation block 201.

[0036] In this embodiment: Through the hexagonal groove 202 opened on the top surface of the installation block 201, the installation block 201 can be rotated by matching a hexagonal wrench with the hexagonal groove 202, and then the screw sleeve body 1 is driven to rotate for installation.

[0037] Specifically, as Figures 1-4 shown, a plurality of first threaded grooves 204 are opened on the top surface of the screw sleeve body 1, and the plurality of grooves 203 on the installation block 201 are respectively threadedly connected with the inner walls of the plurality of first threaded grooves 204 through a plurality of bolts 205.

[0038] In this embodiment: Through the cooperation of the bolt 205 and the first threaded groove 204, the installation block 201 and the top surface of the screw sleeve body 1 can be conveniently and quickly fixed, which is convenient for subsequent installation and fixation of the screw sleeve body 1, and at the same time, it is convenient for the disassembly of the installation block 201.

[0039] Specifically, as Figures 1-6 shown, two second threaded grooves 301 are opened on the top surface of the screw sleeve body 1, fixed threads 303 are opened on the outer walls of the lower ends of the two limiting columns 302, and the outer walls of the lower ends of the two limiting columns 302 are respectively threadedly connected with the inner walls of the two second threaded grooves 301. The upper ends of the two limiting columns 302 are set to be hemispherical.

[0040] In this embodiment: Through the cooperation of the second threaded groove 301 and the limiting column 302, the installation and disassembly of the limiting column 302 can be facilitated, and at the same time, the limiting column 302 can conveniently limit the installation block 201.

[0041] Specifically, as Figures 1-6 shown, two clamping grooves 304 are respectively formed on the outer walls of the two limiting posts 302, and two limiting grooves 305 are formed on the bottom surface of the mounting block 201. The outer walls of the two limiting posts 302 are respectively slidably connected to the inner walls of the two limiting grooves 305.

[0042] In this embodiment: Through the cooperation of the limiting post 302 and the limiting groove 305, the mounting block 201 is limited and fixed.

[0043] Specifically, as Figures 1-6 shown, a plurality of adjusting grooves 306 are arranged inside the mounting block 201. The inner walls of the plurality of adjusting grooves 306 are respectively slidably connected with moving plates 307. Springs 308 are respectively fixedly installed on the sides of the plurality of moving plates 307, and the other ends of the plurality of springs 308 are respectively fixedly connected to the inner walls of the plurality of adjusting grooves 306.

[0044] In this embodiment: Through the plurality of springs 308 provided, the plurality of springs 308 respectively apply elastic forces to the moving plates 307, so that the moving plates 307 receive a continuous thrust.

[0046] In this embodiment: By applying a thrust to the clamping post 309 through the moving plate 307, the clamping post 309 is clamped with the clamping groove 304. The clamping post 309 fixes the limiting post 302, so that the limiting post 302 is not easily loosened from the inner wall of the limiting groove 305, and further limits and fixes the mounting block 201, facilitating subsequent fixing.

[0047] Specifically, the solution is as follows: The cooperation between the second threaded groove 301 and the limit post 302 can facilitate the installation and fixation of the limit post 302. When the installation block 201 moves downward, the limit groove 305 is aligned with the limit post 302, so that the limit post 302 cooperates with the limit groove 305. When the limit post 302 is moved into the limit groove 305, the limit post 302 pushes the clamping post 309 to drive the moving plate 307 to move and compress the spring 308. When the limit post 302 moves to the innermost part of the limit groove 305, the spring 308 pushes the moving plate 307 and the clamping post 309 to move, and the clamping post 309 moves into the clamping groove 304 to fix the limit post 302, so that the limit post 302 is not easily removed from the limit groove 305, ensuring that the installation block 201 is not easily offset, improving the efficiency and quality of subsequent fixation.
