Air damper

Abstract

The invention discloses an air damper. The air damper comprises an outer cylinder, a push rod, a connecting piece, a limiting piece and an exhaust adjusting piece; a cavity is formed in the outer cylinder, one end of the push rod extends into the cavity, the exhaust adjusting piece is arranged at the bottom of the outer cylinder, an exhaust channel is formed in the bottom of the outer cylinder, one end of the exhaust adjusting piece is arranged on the exhaust channel, the push rod is of a hollow structure and is provided with a hollow hole, the connecting piece is connected with the other end of the push rod, one end of the connecting piece extends into the hollow hole, a limiting groove is formed in one side of the connecting piece, one end of the limiting piece is fixed to the push rod, and the other end of the limiting piece extends into the limiting groove. When the push rod is gradually pushed towards one side of the cavity, the push rod compresses air in the cavity, so that the push rod is subjected to resistance of the air in the cavity, and the damping effect is achieved; the overall structure is simple, assembling is convenient, the assembling process is greatly simplified, and the production cost is reduced; and the exhaust adjusting piece is arranged, so that the exhaust speed of the exhaust channel can be adjusted, and the use requirements of different damping forces are met.

Description

technical field [0001] The invention belongs to a mechanical buffer device, in particular to an air damper. Background technique [0002] The dampers used on existing furniture rails are generally hydraulic damping tubes to fix the pressure and use springs to return. In actual use, other mechanical structures are required to assist in the fixation. When used on electric doors and other equipment, additional power consumption of the motor will be increased. At the same time, the structure of the entire damper is complicated, the assembly process is relatively cumbersome, and many accessories are required, which increases the overall volume and production cost, requires more manpower for assembly, and reduces production efficiency. Contents of the invention [0003] An object of the present invention is to provide an air damper capable of solving at least one of the above-mentioned problems. [0004] According to one aspect of the present invention, an air damper is provide...

Problems solved by technology

[0002] The dampers used on existing furniture rails are generally hydraulic damping tubes to fix the pressure and use springs to reset. In actual use, other mechanical structures are required to assist in fixing. When used on electric doors and other equipment, additional power consumption of the motor will be increased.

At the same time, the structure of the entire damper is complicated, the assembly process is relatively cumbersome, and more accessories are required, which increases the overall volume and production cost, requires more manpower for assembly, and reduces production efficiency.
