Damper assembly

A damper assembly for sliding rails of drawers, doors or windows, comprising a shell and a damper body, wherein the damper body comprises a tension piece, a sliding block, a telescopic cylinder and a limiting piece, the sliding block is slidably mounted in the shell, and the tension piece is connected to the shell and the sliding block;

• the sliding block has a first position and a second position in the shell, and the tension piece is capable of pulling the sliding block to move from the first position to the second position;
• the telescopic cylinder is mounted on the sliding block, and the limiting piece is mounted on the shell;
• the limiting piece is provided with a compression surface, one end of the telescopic cylinder abuts against the compression surface directly, and the telescopic cylinder and the limiting piece have a first relative position and a second relative position;
• in a process that the tension piece pulls the sliding block to move from the first position to the second position, the telescopic cylinder moves from the first relative position to the second relative position;
• and in a process that the telescopic cylinder moves from the first relative position to the second relative position, the telescopic cylinder is gradually compressed;
• wherein the shell is a rail;
• the damper body is arranged at at least one end of the rail;
• the sliding block is slidably mounted on the rail;
• the sliding block has a first position and a second position on the rail;
• the tension piece is capable of pulling the sliding block to move from the first position to the second position;
• the limiting piece is a limiting rail;
• the telescopic cylinder is slidably mounted on the limiting rail, and the telescopic cylinder has a first limiting position and a second limiting position on the limiting rail;
• the compression surface is a side wall, the limiting rail is provided with at least one compression surface forming an included angle with a direction of the rail, and the compression surface forming an included angle with the direction of the rail inclines towards the telescopic cylinder from the first limiting position to the second limiting position;
• in the process that the sliding block slides from the first position to the second position, the sliding block drives the telescopic cylinder to move from the first limiting position to the second limiting position;
• and in a movement process, one end of the telescopic cylinder abuts against the compression surface forming an included angle with the direction of the rail;
• and a movement direction of the telescopic cylinder relative to the limiting piece is perpendicular to a compression direction of the telescopic cylinder itself;
• the limiting rail is a conical rail, and a width of the limiting rail is gradually reduced from the first limiting position to the second limiting position;
• and in the process that the telescopic cylinder moves from the first limiting position to the second limiting position, two ends of the telescopic cylinder abut against two side walls of the limiting rail respectively.
