The invention discloses a double-acting buffer. The double-acting buffer comprises a hollow sleeve and a push rod used in match with the sleeve, a guide support piece, a first piston component and a second piston component are arranged inside the sleeve, a passage formed by tube expansion is formed in the sleeve, one end of the push rod penetrates through the guide support piece to be fixedly connected with the first piston component, a compression space is formed between the first piston component and the head portion of the sleeve, a second compression space is formed between the first piston component and the second piston component, a third compression space is formed between the second piston component and the bottom of the sleeve and filled with compressed air, the first compression space and the second compression space are filled with hydraulic damping oil, and the second piston component is symmetrically arranged via double Y-shaped seal rings and can slide inside the sleeve to seal the second compression space and the third compression space in double directions. The double-acting buffer is simple and exquisite in design, material-saving and longer in service life.
Description
technical field [0001] The invention relates to the technical field of double-acting buffers, in particular to a double-acting buffer with simple and exquisite design, material saving and long service life. Background technique [0002] Buffer closing doors can be seen everywhere, such as warehouse and freezer doors are buffer closing doors. At present, the refrigerator has not found the cushioning function. Generally, a seasoning bottle is placed inside the refrigerator door. If the refrigerator door has a cushioning closing function, the performance will be better; and the cushioning closing door can also prevent the door from being hit when it is closed. The ideal situation It is to allow the door to close quickly without bumping. [0003] The problem of the life of the product is that the life of the product in the prior art is mostly 20,000 to 100,000 times, and it adopts a double-layer casing structure, which has a large volume and high cost. [0004] Therefore, ther...
