AI Technical Summary

Technical Problem

In existing aluminum alloy door and window closing structures, the rollers are prone to deformation under the influence of the window's weight, resulting in weakened elasticity and inability to close smoothly, thus affecting ease of use.

Method used

An aluminum alloy door and window closing structure was designed, which includes a convenient adjustment mechanism, an elastic clamping mechanism, and a guide component. The rollers are conveniently adjusted and slide stably through the limit installation component and the rotation adjustment component. Combined with the elastic clamping function of the cleaning brush and cleaning shovel, the rollers are not easily obstructed under the action of gravity.

Benefits of technology

It improves the ease of use and cleaning effect of the aluminum alloy door and window closing structure, ensures that the rollers slide smoothly under the action of gravity, avoids obstruction when contacting the inside of the frame, and enhances the closing effect and cleaning ability.

Abstract

This utility model discloses an aluminum alloy door and window closing structure, including a main body of the door and window closing structure. The main body of the door and window closing structure includes a frame, and two alloy windows are arranged inside the frame. Two closing rollers are arranged at both ends of the alloy windows. A cleaning brush and a cleaning shovel are arranged on one side of the closing roller at the end of the alloy window. By designing a convenient adjustment mechanism, when the main body of the door and window closing structure needs to be disassembled and adjusted, a finger or tool is inserted into the adjustment groove and engages with the outer surface of the handwheel, driving the threaded rod to rotate. The rotation of the threaded rod causes the limit bracket to move downward, and when the limit bracket moves downward, the closing roller moves downward and is inserted into the closing rolling groove, which facilitates the installation and sliding closure of the closing roller. Conversely, the opposite operation is performed to open the closing roller during disassembly, so that the closing roller is easy to adjust and is not easily obstructed by contact with the bottom of the frame when subjected to gravity.
