Axial locking device, piston rod assembly with axial locking device and oil cylinder

Abstract

The invention discloses an axial locking device which comprises a circumferential positioning disc and an outer disc body. An inner gear ring is arranged on the inner side of the outer disc body, a shifting piece is rotatably connected to the circumferential positioning disc, the front end of the shifting piece makes contact with the inner gear ring, the circumferential positioning disc and the outer disc body rotate relative to one direction in the circumferential direction, and an elastic piece is further arranged on the side portion of the shifting piece. The lower end of the elastic pieceabuts against the circumferential positioning disc, the shifting piece abuts against the inner gear ring through elastic force, and the circumferential positioning disc is connected with a first component in a fastened mode. A piston rod assembly is provided with the axial locking device. An oil cylinder is provided with the piston rod assembly. By means of the mode, according to the axial lockingdevice, the piston rod assembly with the axial locking device and the oil cylinder, the operation convenience can be improved, the operation efficiency is improved, the anti-loosening reliability isimproved, and the permanent anti-loosening effect can be achieved on the premise that parts are not broken or crushed.

Description

technical field [0001] The invention relates to the field of anti-rotation and axial loosening prevention mechanisms, in particular to an axial locking device, a piston rod assembly and an oil cylinder with the axial locking device. Background technique [0002] In today's society, mechanical equipment is widely used in various fields of our daily life, and screw connection is indeed an indispensable application of mechanical manufacturing and its mechanical equipment. Threaded connection firmly occupies various fields of mechanical manufacturing due to its simple and efficient connection method, compact structure and reliable connection. However, the disadvantages of threaded connections are also quite obvious, such as long-term use of threaded connections, thread fatigue, increased gap between threaded surfaces, etc. The combined accumulation of these factors leads to thread loosening, especially in some applications that require long-term working of the thread At present...

Problems solved by technology

In comparison, the existing anti-loosening measures require cumbersome manual judgment and monitoring as well as a certain amount of external force support, which is generally labor-intensive and labor-intensive.
