Door and window heat insulation strip with good sealing effect and heat insulation method of door and window heat insulation strip

Abstract

The door and window heat insulation strip comprises a mounting frame, first sealing grooves are formed in the tops of the left side and the right side of an inner cavity of the mounting frame, second sealing grooves are formed in the left side and the right side of the bottom of the inner cavity of the mounting frame, and a sealing strip body is arranged in the inner cavity of the mounting frame. Through cooperative use of a second sealing groove, a mounting cavity, a movable sealing block, a through hole, a top sealing strip, a pressing assembly, a rotating rod, a two-way threaded rod, a rotating piece, a connecting plate, a threaded sleeve, a worm gear, a reset spring, a connecting rod, a movable sliding block, a worm, a limiting sliding block, a sealing plate and a first sealing groove, the problems that an existing heat insulation strip is poor in sealing effect, and the sealing effect is poor after mounting; a gap is easily reserved between the door and the window and the profile, so that the sound insulation and wind resistance of the door and the window are influenced, and meanwhile, external heat is easily caused to enter a room from the gap through the door and the window, so that the sealing effect of the heat insulation sealing strip is influenced.

Description

technical field [0001] The invention relates to the technical field of door and window heat insulation strips, in particular to a door and window heat insulation strip with good sealing effect and a heat insulation method thereof. Background technique [0002] With the improvement of people's living standards and the improvement of the living environment, and the requirements for high thermal insulation and energy saving in the severe cold regions of the north are also constantly improving, the requirements for building doors, windows and curtain walls are also increasing; Using aluminum alloy heat-insulating energy-saving doors and windows or curtain walls, the temperature difference between indoor and outdoor is large in summer and winter, and it is necessary to turn on indoor air conditioners or heaters, which will cause the rapid conduction of indoor and outdoor heat, reducing the utilization rate of energy. Also known as thermal insulation broken bridge aluminum alloy d...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a door and window heat insulation strip with good sealing effect and its heat insulation method, which has the advantages of good sealing and heat insulation performance, and solves the problem that the existing heat insulation strip has poor sealing effect. There is a gap between the profile and the profile, which will not only affect the sound insulation and wind resistance of the doors and windows, but also easily cause the external heat to enter the room through the doors and windows from the gap, thereby affecting the sealing effect of the heat insulation sealing strip
