An embedded silent automatic buffer pulley device

Abstract

The invention discloses an inlaid type muting automatic buffering pulley device comprising a shell, a pulley body, a spring piece, a rotary piece, a magnet, a supporting frame, a buffering wheel, a buffering piece, a connecting rod, a buffering convex block, a first mounting piece, a bearing, a pulley body center shaft, a second mounting piece and a fixing screw. The shell is provided with a connecting fixing hole, a pulley body mounting hole, a rotary shaft mounting hole, a supporting frame mounting hole, a buffering wheel mounting hole and a buffering piece mounting hole. According to the inlaid type muting automatic buffering pulley device, in the using process, the muting effect is good, operation is stable, labor is saved, the smooth effect is achieved, automatic buffering deceleration can be achieved, and noise caused by door collision in moving can be avoided, and the situation that when a door moving mechanism is closed, due to negligence, nearby personnel are pinched, or articles are damaged under clamping of the door moving mechanism is avoided; and the safety degree is high in the using process, the inlaid type muting automatic buffering pulley device can be inlaid in door bodies of different thicknesses and different materials for mounting, and adaptability is good.

Description

technical field [0001] The invention relates to the field of door and window pulley accessories, in particular to an embedded silent automatic buffer pulley device. Background technique [0002] Now in many occasions, more and more doors and windows are designed in the style of sliding doors. Sliding doors are widely used in daily life. For example, sliding door mechanisms are more common in household products, offices, and production workshops. [0003] The more important auxiliary accessories in the sliding door mechanism are the pulleys. The general pulley accessories only have the function of rolling, and the function is very single. Moreover, when using the sliding door, because the ordinary pulley does not have the mute function, during the operation of the sliding door It will generate a certain amount of noise pollution, which will destroy the quiet atmosphere of the surrounding area, and cause the people in the surrounding area to be adversely affected by the noise ...

Problems solved by technology

[0005] On the other hand, the thickness of the door body of the sliding door is inconsistent in many occasions, and the material of the door body may also be different. The general pulley accessories on the market cannot adapt to the problem of flexible installation of pulleys due to different thickness or material of the door body. The adaptability is very large.
