Abstract
The invention discloses a connection loosening-prevention mechanism for a hydraulic rod. The connection loosening-prevention mechanism comprises a piston rod end socket, wherein the piston rod end socket and a connection piece are in threaded connection; a first permanent magnet is arranged at the connection position of the piston rod end socket and the connection piece; a second permanent magnet is arranged at the connection position of the connection piece and the piston rod end socket; the loosening of the piston rod end socket and the connection piece can be prevented by suction force generated by the first permanent magnet and the second permanent magnet.
Description
Technical field
The present invention relates to a kind of hydraulic rod connection anti-loose mechanism.
Background technique
Linkage structure between hydraulic cylinder piston rod end head and the link easily occurs loosening after long-time the use.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the object of the present invention is to provide a kind of hydraulic rod connection anti-loose mechanism, be difficult for loosening.
In order to achieve the above object, technological scheme of the present invention is:
A kind of hydraulic rod connection anti-loose mechanism, comprise piston rod end 1, piston rod end 1 is threaded with link 2, is provided with the first permanent magnet 3 in the joint of piston rod end 1 and link 2, is provided with the second permanent magnet 4 in the joint of link 2 and piston rod end 1.
Advantage of the present invention: the suction by the first permanent magnet 3 and the second permanent magnet 4 produce can prevent the loosening of piston rod end 1 and link 2.
Description of drawings
Accompanying drawing is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
With reference to accompanying drawing, a kind of hydraulic rod connection anti-loose mechanism comprises piston rod end 1, and piston rod end 1 is threaded with link 2, joint at piston rod end 1 and link 2 is provided with the first permanent magnet 3, is provided with the second permanent magnet 4 in the joint of link 2 and piston rod end 1.
Suction by the first permanent magnet 3 and the second permanent magnet 4 produce can prevent the loosening of piston rod end 1 and link 2.
