Pressing mechanism assembly

Abstract

The invention discloses a pressing mechanism assembly. The pressing mechanism assembly comprises a sleeve, a limiting block, a fixed end, a safety spring, an operating spring, a pressing block and a fixed nut, wherein one end of the limiting block is located on the outer side of the upper end of the sleeve, the other end of the limiting block is installed in the sleeve by virtue of an ear piece, and the safety spring is arranged between the ear piece and the inner top surface of the sleeve; a limiting groove which is used for installing the pressing block is formed in the sleeve, the pressingblock is movably installed on the lower end of the sleeve, and the operating spring is installed between the upper end of the pressing block and the inner top surface of the limiting groove; and one end of the fixed end is installed in the limiting groove in the lower end of the ear piece, the other end of the fixed end passes through the operating spring and the pressing block in sequence and then is in threaded connection with the fixed nut, a circle of bulged block is arranged on the fixed end, and the bulged block is located between the operating spring and the limiting groove in the lowerend of the ear piece. According to the pressing mechanism assembly, the pressing and fixed connection between two objects can be realized by manual operation, a conventional screw can be replaced toachieve the fastening effect on some occasions, and the pressing mechanism assembly has the characteristics of small size, simplicity in operation and high reliability.

Description

technical field [0001] The invention relates to the aerospace field, in particular to a pressing mechanism assembly. Background technique [0002] At present, during the use of aerospace ground tooling, it needs to be disassembled and assembled repeatedly. However, in the actual operation of traditional fasteners, fasteners are often missed or dropped. In some cases, common tools cannot be reached. In severe cases, it will cause damage to key equipment. Therefore, it is necessary to design a pressing mechanism to solve the above problems. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a pressing mechanism assembly. [0004] A pressing mechanism assembly of the present invention includes a sleeve, a limiting block, a fixed end, a safety spring, a working spring, a pressing block and a fixing nut; one end of the limiting block is located outside the upper end of the sleeve, and the other One end is installe...
