Abstract

A magnetic-attraction adjustable magnetic-suction-switch for a window screen comprises a pair of magnets or iron bodies which are arranged on the relative position of a pulling beam and a window frame, and at least one of the magnets or iron bodies is a permanent magnet, wherein the magnets is arranged in a magnet box which is arranged in a magnet chute, and the magnet box is provided with an adjusting machine capable of adjusting the magnet box to move in the magnet chute which is arranged on the pulling beam or the window frame, while the window frame and the pulling beam relative to the magnet chute are fixedly provided with the magnets or iron bodies. The invention has the advantages that the invention can adjusts the suction force between the magnets via adjusting the relative position between the magnets by an adjusting screw, wherein the reclosing area of the two magnets can be little at early stage in using and can be increased step by step as extending using time, therefore the suction force of the magnetic-suction-switch can be kept in a required range.

Description

technical field [0001] The invention relates to a magnetic switch for an automatic invisible screen window, in particular to a magnetic switch for a screen window with adjustable magnetic force, which is mainly used for the suction and fixation of the washing beam of the gauze net of the screen window and the window frame. Background technique [0002] The existing screen window magnetic switch adopts the fixed magnetic strip and the magnetic block which are respectively fixed on the opposite surfaces of the tension beam and the lower window frame to attract each other. Its disadvantage is that as the magnetic properties of the magnet decay, the magnetic attraction force of the magnetic switch is reduced to the point that it cannot hold the pull beam. In order to prolong the service life of the magnetic switch, its magnetic force has to be increased, which in turn causes the magnetic switch to have too much suction force at the initial stage of use, causing inconvenience in ...
