Door and window sealing rubber strip changer

Abstract

The invention discloses a door and window sealing rubber strip changer. The door and window sealing rubber strip changer is characterized in that the changer is composed of a first bending plate (1),a second bending plate (2), a third bending plate (3) and a fourth bending plate (4). The door and window sealing rubber strip changer with the structure form is simple in structure, ingenious in design and reasonable in layout; aiming at the problem that a sealing rubber strip arranged in a traditional sliding door and window needs to be changed after being used for a long time, a special changerstructure is designed and comprises a plurality of assemblies, and the assemblies can be assembled into an integrated structure through simple operation; and through the door and window sealing rubber strip changer, sealing strips embedded in door and window frame grooves can be cut down quickly and conveniently and can be taken out of the grooves completely, new sealing strips can further be embedded into the grooves again quickly and conveniently, and thus changing of the sealing strips is achieved.

Description

technical field [0001] The invention relates to an auxiliary tool for sealing doors and windows, in particular to a replacement device for sealing rubber strips for doors and windows. Background technique [0002] Push-pull doors and windows are used a lot. In order to ensure their sealing effect, a sealing strip will be installed in the groove inside the frame of the sliding door and window. After a long period of use, the sealing strip will inevitably age. , After aging, the rubber strip will crack, or become brittle due to loss of elasticity, or even fall off directly from the frame of the door and window, losing the sealing effect. [0003] In this way, it is necessary to replace the invalid sealing strip regularly. The groove of the rubber strip of the door and window is in the shape of an inverted T, and for the bottom of the sealing strip suitable for the above-mentioned inverted T shape, it is difficult to clean it out of the groove quickly and conveniently, especia...

AI Technical Summary

Problems solved by technology

The groove of the rubber strip of the door and window is in the shape of an inverted T, and for the bottom of the sealing strip suitable for the above-mentioned inverted T shape, it is difficult to clean it out of the groove quickly and conveniently, especially when the rubber strip ages and becomes After hardening, it is very easy to break during the replacement process. Once the above problems occur, the root of the rubber strip will remain in the groove of the door and window frame, which is difficult to completely remove, so it is also impossible to reinstall the new sealing strip smoothly. in the groove

Sometimes in order to replace the sealing strip, it is even necessary to physically destroy the door and window frames, but if this is done, the overall service life of the sliding doors and windows is bound to be greatly reduced
