Door window mullion connecting structure convenient to adjust and fix

Abstract

The invention discloses a door window mullion connecting structure convenient to adjust and fix. According to the technical scheme, the door window mullion connecting structure convenient to adjust and fix is characterized in that a heat insulation strip is rotationally connected with a positive and negative screw rod, a positive thread and a negative thread of the positive and negative screw rod are in thread connection with sealing plates, the sealing plate is attached to the inner side wall of an opening of the heat insulation strip, and the heat insulation strip is provided with a driving assembly which drives the positive and negative screw rod to rotate; and the driving assembly comprises a sealing degree detecting module, a sealing degree detecting module, a pressure value comparison module and a driving device, wherein the sealing degree detecting module comprises a pressure sensor, the pressure value comparison module compares a received pressure value detecting signal with a preset reference value, when the pressure value detecting signal is less than the preset reference value, a driving signal is controlled to be output, and when the driving device receives the driving signal output by the pressure value comparison module, the positive and negative screw rod is controlled to rotate so as to control the sealing plate to move towards the two ends. By means of the door window mullion connecting structure convenient to adjust and fix, the fact that after being used for a long term, the sealing plate is adjusted to make the heat insulation effect of aluminum alloy doors and windows be increased, and the technical effect of the practicability of the aluminum alloy doors and windows is improved.

Description

technical field [0001] The invention relates to an aluminum alloy door and window, in particular to a conveniently adjustable and fixed door and window mullion connection structure. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fans. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows made of aluminum alloy as a force-bearing member (a member that bears and transmits its own weight and load) and wood, plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows, and the quality of aluminum alloy doors and windows can be Make a rough judgment from the selection of raw materials (aluminum profiles), the surface treatment of aluminum materials, the quality of internal processing, and the price of a...

Problems solved by technology

[0003] The existing Chinese patent with application number 201010253087.5 can be referred to, which discloses a mullion and outer frame structure of an aluminum alloy inward opening and inversion window frame, and mullion guide rails are arranged on both sides or one side of the lower frame of the mullion The lower frame and the upper frame structure of the stile guide rail are provided with a stile PVC guide rail in the cavity of the stile guide rail. One side of the gauze is buckled into the stile PVC guide rail. The upper frame structure of the frame and the outer frame guide rail is provided with the outer frame PVC guide rail in the outer frame guide rail cavity, and one side of the gauze is buckled into the outer frame PVC guide rail. Insufficient strength and fastness caused by the split structure, the problem of material waste and time-consuming, also solves the problem that the split screen track is easy to cause damage to the invisible screen window, and the problem of poor mosquito and windproof effects. The profile structure with the outer frame has the characteristics of high strength, convenient installation and use, water tightness, heat insulation, good sound insulation effect, strong windproof ability of the screen window, and the gauze net is not easily damaged

[0004] However, the mid-stile structure will undergo structural changes during long-term heat preservation and use, resulting in poor heat preservation effect and affecting the normal use of aluminum alloy doors and windows.
