Problems solved by technology

In the prior art, the opening and closing of the sliding door is mostly done by manpower, which is very inconvenient for occasions that often need to open and close the sliding door, such as cold storage
In particular, when the sliding door is closed, due to the effect of inertia, the sliding door is likely to collide with the door frame, which not only generates noise, but also easily causes damage to the sliding door and its accessories, greatly reducing its service life

Abstract

The invention discloses a sliding door pulling and buffering device which is composed of a pulling device and a buffering device. The pulling device comprises a shell, a rotating shaft and a winding drum. The rotating shaft is movably supported in the shell, one end of a winding spring is fixed on the rotating shaft while the other end of the same is fixed on the winding drum, a pulling rope is fixed on the outer surface of the winding drum, and one end of the pulling rope can extend out of the shell. The buffering device comprises a cylindrical body and a piston rod. A piston is arranged at one end of the piston rod, the outer surface of the piston contacts with the surface of an inner cavity of the cylindrical body, and an air hole is formed at the bottom end of the inner cavity of the cylindrical body. The sliding door pulling and buffering device has the advantages that the device is simple in structure and convenient to use, sliding speed of a sliding door can be reduced automatically and effectively, noise is reduced, service lives of the sliding door and accessories thereof are prolonged, and the like.

Description

technical field [0001] The invention relates to a traction and buffer device for a door, in particular to a traction and buffer device for a sliding door. Background technique [0002] Because the opening and closing of the sliding door takes up less space, it is widely used in warehouses, cold storage and other occasions. In the prior art, the opening and closing of the sliding door is mostly done by manpower, which is very inconvenient for occasions where the sliding door often needs to be opened and closed, such as a cold storage. Especially, when the sliding door is closed, due to the effect of inertia, the sliding door is likely to collide with the door frame, which not only generates noise, but also easily causes damage to the sliding door and its accessories, greatly reducing its service life. Contents of the invention [0003] The purpose of the present invention is to provide a sliding door traction and buffering device which can make the sliding door close autom...
