Buffer structure and oil cylinder

Abstract

The invention discloses a buffer structure. The buffer structure comprises a cylinder barrel, a cylinder bottom arranged on the cylinder barrel, a piston rod which is movably arranged in the cylinderbarrel and a piston which is mounted on the piston rod, wherein the piston is used for dividing the cylinder barrel into a first oil cavity and a second oil cavity; the cylinder bottom is positioned at the right side of the piston; a plurality of channels are arranged inside the piston; a valve element assembly is correspondingly arranged in each channel; the two ends of the valve element assemblyextend out of the two ends of each channel; and the piston rod drives the piston to move, so that the valve element assembly is contact with an opening part of each channel to form a sealing surfacefor disconnecting the first oil cavity or the second oil cavity or the valve element assembly is separated from the end part of the channel for enabling the first oil cavity to be communicated with the second oil cavity. The hydraulic oil cylinder comprises the buffer structure. In this way, the buffer structure and the oil cylinder can save space for buffering the piston, so that a hydraulic element is protected, and integral stability is ensured.

Description

technical field [0001] The invention relates to the field of oil cylinders, in particular to a buffer structure and a hydraulic oil cylinder. Background technique [0002] The existing buffer structure is to change and adjust the buffer gap or increase the angle of the flat wire, or to increase the pressure by changing the cross section to generate back pressure to play a buffer role, and this method can only play a buffer role in one direction, and at the same time for the buffer The section has higher requirements, and the buffer pressure needs to be tested to prevent the oil cylinder from being damaged due to excessive buffer pressure. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a buffer structure and an oil cylinder, which can save space while buffering the piston, protecting hydraulic components and ensuring overall stability. [0004] In order to solve the above-mentioned technical problems, a technic...
