Abstract

The invention discloses a sleeve type bothway extending-out threaded rod. The sleeve type bothway extending-out threaded rod comprises a sleeve with openings in the two ends and a threaded rod sleevedwith the sleeve, an external thread is arranged on the outer surface of the threaded rod, the length of the threaded rod is larger than the length of the sleeve, the threaded rod extends out from thetwo ends of the sleeve, ball grooves arranged in a thread line manner are further arranged inside the sleeve, and balls are further arranged in the ball grooves. According to the sleeve type bothwayextending-out threaded rod, through rolling design of the balls, abrasion generated during relative movement of the sleeve and the threaded rod and the rusting condition can be greatly reduced, the threaded rod can be smoothly screwed in and screwed out, and the service life of the overall device is prolonged.

Description

technical field [0001] The invention relates to a mechanical connector, in particular to a sleeve-type two-way protruding threaded rod. Background technique [0002] The connection structure of the existing threaded rod is usually provided with an internal thread in the casing, and the threaded rod is provided with a corresponding external thread for connection and installation, and can be extended and recovered after rotation; the existing structure is used for a long time. Under the condition of rust and wear, it will cause the internal and external thread rotation to protrude and get stuck, and it will be more laborious to use the rotation. Contents of the invention [0003] The object of the present invention is to provide a sleeve-type bidirectionally protruding threaded rod aiming at the deficiencies in the prior art. [0004] Technical solution: The technical solution adopted by the present invention to solve the problem is: a sleeve-type two-way protruding threade...
