Abstract

The invention discloses an automatic hydraulic cylinder. The automatic hydraulic cylinder comprises a body, a piston, a sealing piece, a lower push rod, an actuating rod and a reset piece, wherein the body is provided with an inner cavity, the upper portion of the inner cavity is provided with a water inlet and an upper push rod, and the lower portion of the inner cavity is provided with a through hole; the piston is arranged in the inner cavity in a sliding and sealing manner, moves between an initial position and a final position, and is provided with a pressure relief hole; the sealing piece is movably arranged in the piston and moves between an opening position and a closing position; the lower push rod is arranged below the inner cavity and is opposite to the sealing piece; the actuating rod is fixedly arranged on the piston and penetrates through the through hole to extend downwards; and the reset piece provides reset force for the piston. In the initial state, the lower push rod pushes the sealing piece to close the pressure relief hole, and in the final position, the lower push rod pushes the sealing piece to open the pressure relief hole. Automatic reciprocating motion of the piston can be achieved, and therefore the automatic drainage function of a closestool drainage valve can be triggered by means of the characteristics of the piston. The structure is simple, the number of parts is small, and cost is low.

Description

technical field [0001] The invention relates to a hydraulic cylinder, in particular to an automatic hydraulic cylinder. Background technique [0002] In the existing piston-type hydraulic cylinder, the shell of the hydraulic cylinder is generally fixed on the basic object, and the piston of the hydraulic cylinder moves and drives the working mechanism to move by inputting or discharging medium oil. In the prior art, the reciprocating movement of the hydraulic cylinder piston is generally achieved by using a reversing valve to control the input and output of the hydraulic cylinder. It has many parts, complex structure and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention aims at the above-mentioned deficiencies in the prior art. An automatic hydraulic cylinder is provided, which has a simple structure, few parts and low cost. [0004] In order to achieve the above object, the technical solution adopted in the presen...
