Abstract

The invention discloses a noise reduction piston rod. The noise reduction piston rod comprises a piston rod body, a piston, a sealing assembly and a connecting base, wherein the lower end surface of the piston rod body is fixed to the upper end surface of the piston; a convex groove is formed in the lower end surface of the piston; a fixing block is fixed to the lower end of the inner ring of the convex groove formed in the lower end surface of the piston; the connecting base is fixed to the lower end of the fixing block; and the sealing assembly is arranged on the piston. Compared with the prior art, the noise reduction piston rod has the following beneficial effects that when the piston rod ascends, a sealing ring can be tightly attached to the inner wall of an oil cylinder or an air cylinder to achieve the sealing effect; when the piston rod descends, the sealing ring can be shrunk, and sliding friction of the piston rod is reduced, so that the piston rod descends more easily, and meanwhile, noise is reduced; when the piston rod ascends, sound absorption holes and sound absorption cotton can achieve a good noise reduction effect; and when the piston rod descends, attached dirt can be pushed out, the sound absorption holes are prevented from being blocked, so that the noise reduction effect is improved.

Description

Technical field [0001] The present invention belongs to the technical field of piston rod, and in particular, to a noise reduction piston rod. Background technique [0002] The piston rod is a connecting member that supports the piston work, most of which is used in the cylinder, the cylinder motion execution unit, is a moving member that moves frequently and high technology requirements. The piston rod is mainly used in hydraulic pneumatic, engineering machinery, cars, cafes, packaging machinery, packaging machinery, roller shaft, textile machinery, conveyance machinery, and linear optical axes for linear motion. However, the traditional piston rod does not have noise reduction function, and noise elimination in the operation process of the piston rod is not possible, and the working stability is reduced. Now there is an urgent need for a noise-saving piston rod to solve this problem. Inventive content [0003] For the shortcomings of the prior art, the present invention is an ...
