Magnetic repulsion type ball holding rolling door/window

Abstract

The invention relates to the technical field of building doors and windows, in particular to a magnetic repulsion type ball holding rolling door / window. The magnetic repulsion type ball holding rolling door / window comprises a sliding seat arranged inside a door / window frame. Movable fan bodies are arranged on the sliding seat, and ball holding rolling devices are arranged between the sliding seat and the fan bodies. Each ball holding rolling device comprises two ball holding semicircular arms which are oppositely arranged, each ball holding semicircular arm comprises an arc plate with a semicircular cross section, a rolling channel is formed between every two corresponding arc plates, and a plurality of steel balls are arranged in each rolling channel. A plurality of evenly distributed magnet separation blocks are arranged inside each rolling channel. Magnetic poles of opposite sides of every two adjacent magnet separation blocks are the same, and each steel ball is arranged between every two adjacent magnet separation blocks. According to the magnetic repulsion type ball holding rolling door / window, the principle that the magnet separation blocks opposite in magnetism repel is utilized, the multiple magnet separation blocks are arranged in the rolling channels, the structure is simple, the manufacturing cost is low, and the steel balls will not be stuck; besides, each steel ball revolves on its axis instead of rolling, so that the steel balls are not prone to damage, the service life of the steel balls is long, and normal use of the magnetic repulsion type ball holding rolling door / window is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building doors and windows, in particular to a magnetic repelling ball-holding rolling door and window. Background technique [0002] With the continuous development of society, the requirements of people's quality of life are also constantly improving. In terms of home decoration, sliding doors and windows with convenient use, good sealing, heat insulation and sound insulation effects have been widely used. At present, commonly used sliding doors and windows, in order to achieve the effect of moving, generally all are to adopt fixed pulley, thereby realize the movement of doors and windows. [0003] However, if the fixed pulley is used, the structure of the pulley is complex. Due to the need for frequent switches, the pulley needs to work frequently, and problems such as pulley cracks, ellipse, and iron sheet rust are prone to occur. At present, the pulleys used for sliding doors and windows have a short...

[0003] However, if the fixed pulley is used, the structure of the pulley is complex. Due to the need for frequent switches, the pulley needs to work frequently, and problems such as pulley cracks, ellipse, and iron sheet rust are prone to occur. At present, the pulleys used for sliding doors and windows have a short service life. -It needs to be replaced once every 5 years, which not only increases the cost, but also takes time and effort, and when the pulley slides to the distance limiter, it is prone to jamming, which will affect the movement of doors and windows
