Magnetic attraction sealing structure of novel door window sash

Abstract

The invention provides a magnetic attraction sealing structure of a novel door window sash. The magnetic attraction sealing structure comprises a mounting groove located in a door window sash frame, and a movable frame which can stretch out and shrink inwards from the interior of the mounting groove is connected with the mounting groove; a magnetic material block is arranged in the movable frame, and a flexible sealing strip is arranged on the outer side of the movable frame; an inner guide cylinder body is arranged on the movable frame, and the inner guide cylinder body and an outer guide cylinder body mounted on the door window sash frame are sleeved together; and a bolt penetrates the inner guide cylinder body, the head end of the bolt is fixedly connected to the head end of the outer guide cylinder body, and a spring is arranged between the bolt and the inner guide cylinder body. When a magnetic attraction sealing device is used, the device is used on a door wind outer frame and a door window sash fixed frame. Due to existence of the inner guide cylinder body and the outer guide cylinder body, the motion guide performance of the movable frame body is good, durable performance of a whole door window is improved, and the use noise is low. Due to existence of a flexible protection piece strip, the aim that after air bends, the air normally flows is achieved. The airtight performance, watertight performance, sound insulation performance, heat preservation performance and durable performance are improved.

Description

technical field [0001] The invention provides a sealing structure for a door and window, in particular a magnetic sealing structure for the gap of the door and window. Background technique [0002] At present, the magnetic sealing structure of the door and window, as described in the document disclosed by the applicant in the patent application of CN202064799U, is that the magnetic sealing device is installed in the installation groove of the door and window frame by springs and screws. It only solves the sealing between the gaps between the doors and windows. And the gap in the magnetic sealer and the door and window sash body cannot solve the sealing, and the air flows as usual after turning in the installation groove, and the sealing effect of airtight, watertight and sound insulation is relatively poor. In addition, when in use, the magnetic material in the door and window frame is relatively attracted to the magnetic sealer in the other door and window, and the direct ...

AI Technical Summary

Problems solved by technology

However, the gap between the magnetic sealer and the door and window frame cannot be sealed, and the air flows as usual after turning from the installation groove, and the airtight, watertight and sound insulation sealing effects are poor

In addition, when in use, the magnetic material in the frame of the door and window sash and the magnetic sealer in the other door and window sash are relatively attracted, and the direct friction between the magnetic sealer and the screw produces a strong noise, and the magnetic sealer is easily worn and deteriorated.
