A two-way shock absorber for large cabinets capable of adjusting damping force and a cabinet equipped with a two-way shock absorber

Abstract

The invention relates to a bidirectional shock absorber with adjustable damping force for a double-board sliding type double-acting cylinder type large cabinet and the cabinet provided with the bidirectional shock absorber, wherein the large cabinet stores objects on shelves. The bidirectional shock absorber with the adjustable damping force comprises a cylinder shell, a piston rod, a first striking stick, a second striking stick, a first spring and a second spring, one side wall, the cylinder shell and a first piston make up a first chamber, the cylinder shell, the first piston and a second piston make up a second chamber, and the cylinder shell, the second piston and the other side wall make up a third chamber; the first spring is located between the side wall and the first piston and used for providing restoring force to the first piston; the second spring is located between the other side wall and the second piston and used for providing restoring force to the second piston. The damping force of the bidirectional shock absorber is adjustable, and the impact force to a fixed body part due to opening and closing drawer bodies is effectively reduced; the bidirectional shock absorber with the adjustable damping force generates certain beneficial effects.

Description

technical field [0001] The present invention relates to a two-way shock absorber for large cabinets of double-action cylinder type with adjustable damping force and two-way shock absorbers for large cabinets that mainly store heavy objects (for example, more than 100Kg) in a shelf-type. appliance cabinet. Background technique [0002] Registered Patent No. 10-1054003 discloses a cabinet of a novel structure in which a door can be accommodated inside a side panel. In the past, cabinets for storing heavy objects did not have impact absorbing devices. The impact force between the drawer body and the main body was large, which was inconvenient to use. . Especially when iron products are stacked and discharged in boxes, 5 to 50 boxes are stored on shelf-type drawers. In this case of heavy weight, especially when the weight is more than 100-300Kg, the above-mentioned problems are more prominent. . Contents of the invention [0003] The present invention aims to solve the abo...
