Abstract

The invention provides an anti-loose structure, and particularly relates to a set screw radial anti-loose structure which is mainly suitable for loose prevention between various hydraulic cylinder pistons and piston rods or guide sleeves and the cylinder barrels. The anti-loose structure comprises a rod body and a piston, wherein the rod body is connected with the piston through threads, and the rod body and the piston are fixed through a screw. The piston has the tendency to rotate around the rod body, the rod body rotates along with the piston under the effect of the set screw, and thus reliable connection between the piston and the rod body is ensured. The anti-loose structure saves production cost and is simple in structure, convenient to machine and mount, reliable in anti-loose effect and high in adaptability.

Description

technical field [0001] The present invention designs an anti-loosening structure, specifically a set screw radial anti-loosening structure, which is mainly suitable for anti-loosening between pistons and piston rods of various hydraulic cylinders or between guide sleeves and cylinder barrels. Background technique [0002] At present, there is no uniform standard and regulation for the anti-loosening form used for hydraulic cylinder pistons or guide sleeves. There are glue anti-loosening, spot welding anti-loosening, and double nut anti-loosening. The quality of the anti-loosening measures directly affects the overall performance and quality of the hydraulic cylinder. In order to improve the service life and performance of the hydraulic cylinder, ensure the safety and reliability of the hydraulic cylinder. Effectively prevent thread failure such as thread loosening and leakage caused by the circumferential rotation of the piston between the rod body and the piston. Content...
