Abstract

The invention discloses a double-outlet-rod type damping buffer. The damping buffer comprises a rod shaft, a shell, oil seal structures, a balance structure, a first spring and a second spring; the shell is cylindrical, the rod shaft is located in the shell and penetrates out of the two ends of the shell, and damping oil is contained in the shell; the first oil seal structure is fixed to the upper end of the shell, and the second oil seal structure is fixed to the lower end of the shell; the balance structure is arranged in the shell, the rod shaft penetrates through the balance structure, the balance structure comprises a balance sleeve, a balance plug and a first sealing ring, an oil channel is formed in the balance sleeve, and when the balance sleeve and the balance plug make contact with the protruding block at the same time for limiting, the balance plug partially blocks the oil channel; the first spring is located in the upper oil chamber; the second spring is located in the lower oil chamber. Compared with the prior art, the damping buffer has the advantages that the working process is gentle and stable, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of buffers, in particular to a double-outlet rod type damping buffer. Background technique [0002] Spring buffers are generally composed of sealing structure, oil passing structure, spring structure, rod shaft, oil chamber and damping oil, and are widely used in various seats, furniture drawers, cabinets, doors, handles, various small and medium-sized boxes, etc. For clamshell, telescopic and sliding products, it has the effect of shockproof and slows down the speed of door opening and closing. Press the rod shaft under the action of external force, and the spring will perform a compression action, which can remove the external force, so as to achieve the effect of protecting the device and reduce noise. However, in the prior art, the reset of the rod shaft depends entirely on the rebound force of the compressed spring. During the rebound process, the rod shaft cannot move smoothly, the rebound process is ...
