Shockproof connecting screw for natural science archaeological fixing device

Abstract

The invention discloses a shockproof connecting screw for a natural science archaeological fixing device. The connecting screw comprises a first cylinder segment, a middle segment and a second cylinder segment. One end of the middle segment is connected with the first cylinder segment, and the other end of the middle segment is connected with the second cylinder segment; the middle segment is in a cubic shape, and each side face of the middle segment is provided with a groove for containing damping materials; and the first cylinder segment, the middle segment and the second cylinder segment are of an integral structure, and the diameter of the first cylinder segment is smaller than a half of the diameter of the second cylinder segment. The shockproof connecting screw is provided with a plurality of grooves, and sponge strips are placed in the grooves; and vibration caused by shaking of a connecting part can be effectively reduced, and firmness of connecting between the connecting screw and the connecting part is improved. The shockproof connecting screw for the natural science archaeological fixing device is simple in structure and has the shakeproof function; and vibration along with shaking of the connecting part can be avoided.

Description

technical field [0001] The invention relates to the technical field of mechanical fasteners, in particular to an anti-vibration connecting screw used for natural archaeological fixtures. Background technique [0002] In mechanical connection, connection screw is the most widely used as a commonly used fastener, and is often used for fastening connection between two metals. However, the connecting screws in the prior art often have the defect of vibrating along with the movement (vibration) of the connecting body, resulting in an unreliable connection. [0003] Therefore, it is necessary to provide an anti-vibration connecting screw for natural and archaeological fixtures, which has an anti-vibration function and can avoid vibration with the vibration of the connecting piece, so as to overcome the above-mentioned technical defects. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an anti-vibration connection screw...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an anti-vibration connection screw for natural history and archeology fixtures, which has anti-vibration function and can avoid vibration with the vibration of the connecting piece, so as to overcome the problem that the connection screw often exists with the connection body in the prior art. The jitter produces vibration, which leads to the defect of unreliable connection
