Problems solved by technology

[0002] At present, for the fastening connection between two plate-shaped parts, there are mainly two methods of self-tapping screw and ordinary screw connection. The connected parts are damaged, and it is difficult to reconnect once they are disassembled; to connect with ordinary screws, it is necessary to install a nut at one end of the screw. Sometimes due to the limited assembly space, it is very inconvenient to install the nut on the screw. Therefore, for plastic parts, the nut is often directly embedded in one end of the connection hole in the plastic forming process. Although this facilitates the screw connection operation during assembly, once the nut fails due to sliding pressure or other quality problems, it will be damaged. Lead to the scrapping of the entire joined plastic part
[0003] In addition, clips are also used to connect two plate-shaped parts with self-tapping screws or ordinary screws. Screws are installed on the parts. In this connection method, the assembly holes must be clamped on the edge of the parts, and when assembling, the holes for the screws on the clips, the assembly holes on the two-plate parts and the axis of the screws must be in a straight line. , once misplaced, it cannot be assembled

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 As shown, the nut 1 is integrally embedded in the inner hole of one end of the buffer bush 2, the other end of the buffer bush 2 is provided with a radially outward boss 21, and the outer wall of the buffer bush is provided with an annular protrusion twenty two.

[0016] see figure 2 , when assembling and connecting, first install the buffer bushing 2 in the bolt hole of the first connecting piece 3, so that the first connecting piece 3 is limited between the boss 21 and the annular protrusion 22, and the end of the buffering bushing 2 The boss 21 and the surface of the first connecting piece 3 are well bonded, and then the bolt holes of the second connecting piece 4 are aligned with the inner holes of the buffer bushing 2 and fit together, and finally the screw 5 is screwed on, and the whole process does not need to use The nut is...

Abstract

The invention provides a buffering connecting nut and a nut body(1) is embedded and arranged in an inner hole on one end of a buffering bush(2) in an integrated way; the other end of the buffering bush(2) is provided with a boss(21) which is along the radial direction and outward; the outside wall of the buffering bush(2) is provided with a ring shaped salience(22), specially, the boss(21) on the end of the buffering bush(2) is a disc cingulum. The adoption of the invention can conveniently and quickly connect two parts with common screws and is not limited by assembly space. The connecting part is provided with buffering and damping function so that the connecting reliability can be improved.

Description

technical field [0001] The present invention relates to nuts, especially nuts with buffer connection function. Background technique [0002] At present, for the fastening connection between two plate-shaped parts, there are mainly two methods of self-tapping screw and ordinary screw connection. The connected parts are damaged, and it is difficult to reconnect once they are disassembled; to connect with ordinary screws, it is necessary to install a nut at one end of the screw. Sometimes due to the limited assembly space, it is very inconvenient to install the nut on the screw. Therefore, for plastic parts, the nut is often directly embedded in one end of the connection hole in the plastic forming process. Although this facilitates the screw connection operation during assembly, once the nut fails due to sliding pressure or other quality problems, it will be damaged. Lead to the scrapping of the entire connected plastic parts. [0003] In addition, clips are also used to con...
