Title:
HYDRAULIC OIL CYLINDER WITH ANTI-SHEAR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/128131
Kind Code:
A1
Abstract:
A hydraulic oil cylinder with an anti-shear structure, comprising an oil cylinder (1), an oil storage tank (2), and a piston (3). The piston (3) is slidably assembled in the oil cylinder (1). The inner space of the oil cylinder (1) is divided into a rodless cavity (101) and a rod cavity (102) by means of the piston (3). The rodless cavity (101) is communicated with the inner space of the oil storage tank (2). The oil storage tank (2) is coaxially connected to the oil cylinder (1) by means of assembly cooperation of a logic valve cover (4) and an oil cylinder rear cover (5). The logic valve cover (4) is provided with a valve accommodating cavity (401) used for accommodating a logic valve (6). The end face of the logic valve (6) is flush with the end face of the logic valve cover (4). The logic valve cover (4), the logic valve (6), and the oil cylinder rear cover (5) are provided with an oil pipeline communicating the oil storage tank (2) with the oil cylinder (1). The hydraulic oil cylinder can obviously lower the machining and assembling difficulty, and reduce the production cost. In addition, the hydraulic oil cylinder can be used as long as an oil pipeline in a valve element of the logic valve is communicated with an oil hole of the logic valve cover and an oil hole of the oil cylinder rear cover even if the assembling positions of the logic valve cover and the oil cylinder rear cover are deviated slightly, and thus the stability and durability of the hydraulic oil cylinder are greatly improved.
