A liftable self-adaptive pulley device

Abstract

The invention discloses a liftable self-adaptive pulley device which comprises a shell, a pulley body, a spring leaf, a rotary sheet, a magnet, a supporting frame, a buffer wheel, a buffer sheet, connection rods, a top plate, a rotary frame, a rotary fixed sheet, a lifting screw rod, a buffer bulge, bearings, a pulley body center shaft and connection screw rods. In the use process, the liftable self-adaptive pulley device provided by the invention is good in muting effect, stable in running and smooth in labor conservation, can realize automatic buffer and speed reduction, can avoid noises caused by collision of sliding doors, avoid persons nearby from being hurt by jamming when a sliding door mechanism is closed due to negligence or avoid the condition that the sliding door mechanism collides an object nearby to cause damage of the object, is high in safety degree in the use process and good in thickness and shape adaptability of a door body, can realize self-adaptive flexible regulation on the thickness of the door body during mounting, can realize easy and flexible up and down regulation of a height of the sliding door body and meets the lifting demand of a user under a specialcondition.

Description

technical field [0001] The invention relates to the field of door and window pulley accessories, in particular to a liftable self-adaptive 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 pollution. ...

AI Technical Summary

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. Difference

[0006] Common pulley accessories still cannot flexibly adjust the lifting height of the door body after installation, and cannot meet the special requirements of users for flexible adjustment of the door body lifting under special circumstances
