An exterior-mounted silent automatic buffer pulley device

Abstract

The invention discloses an external mute automatic buffering pulley device comprising a shell, a pulley body, a spring piece, a rotating piece, a magnet, a support frame, a buffer wheel, a buffer piece, connecting rods, a convex buffer block, a bearing and a pulley body center shaft. The shell is provided with a connection fixing hole, a pulley body mounting hole, a rotating shaft mounting hole, asupport frame mounting hole, a buffer wheel mounting hole, a locating mounting hole and a buffer piece mounting hole. The pulley device disclosed by the invention has the advantages of good mute effect, stable operation, labor saving and smoothness, and the process of automatic buffering and slow-down and automatic recovery can be achieved; noise caused by collision of moving doors can be avoided, and the conditions that persons nearby are pinched due to negligence or articles nearby are collided and damaged by a door movement mechanism when the door movement mechanism is closed are avoided;and the safety is high in the using process, and the purpose of lifting the door body can also be achieved.

Description

technical field [0001] The invention relates to the field of door and window pulley accessories, in particular to an exterior-mounted 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 th...

[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 produce a certain amount of noise pollution, destroying the quiet atmosphere of the surrounding area, and causing people in the surrounding area to be adversely affected by noise pollution

[0004] In addition, sometimes the user does not pay attention to the situation of people or objects around the sliding door mechanism due to negligence. loss
