Connecting mechanism capable of improving fixing efficiency

Abstract

The invention discloses a connecting mechanism capable of improving fixing efficiency. The connecting mechanism comprises two connecting heads, bolts and nuts. One ends of the connecting heads are hinged to each other, and the ends of the bolts are in threaded connection with the nuts thread after passing through the other ends of the two connecting heads. A mounting groove is formed in the end face of the connecting head with the nut, and the opening size of the mounting groove is smaller than the bottom size. A end face, near the head of the bolt, of the nut is provided with a mounting bar The cross-sectional dimension of the mounting bar is the same as the cross-sectional dimension of the mounting groove, and the axis of the mounting bar intersects with the axis of the nut perpendicularly, and the threaded hole in the nut runs through the mounting bar; a rubber ring is disposed on the end face of the bolt near the nut. The axis of the rubber ring coincides with the axis of the bolt,and the rotary bolt enables the rubber ring and the connecting head to make contact. The installation of the mounting groove and the mounting bar not only fix the nuts and prevent the nuts from rotating, then enhance the stability of the clamp in use.

Description

technical field [0001] The invention relates to the petroleum field, in particular to a connection mechanism for improving fixing efficiency. Background technique [0002] The clamp is a connecting device for connecting grooved pipe fittings, valves and pipeline fittings. It is used to tighten the coupling between the quick joints. Generally, the two joints have gaskets, rubber, silicone and PTFE. It has good performance, high sealing degree and easy installation. [0003] Clamps are mainly divided into steel wire clamps and cast iron clamps. Among them, the steel wire clamp has the characteristics of beautiful appearance, convenient use, strong clamping force and good sealing performance. It is mainly used for connection, fastening and sealing of ordinary rubber hoses, nylon plastic hoses, cloth hoses, hoses and other interfaces of vehicles, ships, diesel engines, gasoline engines, machine tools, firefighting, and other mechanical equipment and chemical equipment; cast ir...

Problems solved by technology

[0007] The purpose of the present invention is to provide a connection mechanism that improves the fixing efficiency, and solves the problem that with the transportation of the fluid in the pipeline, the fluctuation of the fluid will drive the pipeline to vibrate, and then the nut will rotate relative to the bolt, causing the clamp to loosen and lose its function of connecting and fixing the pipeline
