Problems solved by technology

When the piston of this structure moves sharply, the deformation of the damping plate increases, and the channel through which the damping medium flows will be excessively blocked, causing the piston rod to withstand a large impact and easily bend. In order to avoid the above situation, it is necessary to further improve the structure. perfection

Abstract

A damper for furniture, including a piston rod, a piston and a valve plate arranged in the cylinder body, one end of the piston rod is fixedly connected with the piston, and the other end protrudes out of the cylinder body, and it is characterized in that the piston and / or the valve plate are provided with zigzag The oil passage is composed of an end face groove arranged on the end face of the piston and / or valve plate, and an oil passage that communicates with the end face groove and communicates with both ends of the piston and / or valve plate, wherein the end face groove is not It directly leads to the inner wall of the cylinder; when the zigzag oil passage is arranged on the piston, the valve plate is provided with an oil passage connecting the zigzag oil passage of the piston; The oil passage of the oil passage; when both the piston and the valve plate are provided with zigzag oil passages, the zigzag oil passages of the two are connected to each other. When the damping movement of the piston of the present invention ensures that the quantitative damping oil flows through the tortuous oil passage, it does not cause impact on the cylinder wall, thereby greatly improving the service life of the damper.

Description

technical field [0001] The invention relates to a damper, in particular to a furniture damper suitable for furniture hinges, drawer slide rails and the like. Background technique [0002] I disclose a damper for furniture in Chinese Patent No. ZL 200720060587.0. The damper includes a piston rod set in the cylinder body. One end of the piston rod is connected to the piston, and the middle part is connected to the seal. The damping plate and the limiting plate in the body, the piston, the damping plate and the limiting plate are connected in sequence, one end of the piston rod extends into the cylinder body, passes through the limiting plate and the damping plate, and connects with the piston, and the outside of the piston is provided with One or more axial gaps, an annular step is provided on the side of the damping plate facing the limiting plate, and a short positioning column is arranged on the side of the limiting plate facing the damping plate, between the piston, the da...
