External connecting piece suitable for connecting mullions of aluminum alloy doors and windows

Abstract

The invention discloses an external connecting piece suitable for connecting mullions of aluminum alloy doors and windows, relates to the technical field of door and window accessories, and solves theproblems that an existing connecting piece is strenuous to install and the interior of the existing connecting piece is easy to corrode. The external connecting piece comprises an external frame, twosets of connecting pieces are fixedly and symmetrically arranged on the front side and the rear side of the top of a connecting piece supporting plate, connecting piece fixing bolts sequentially penetrate through the connecting pieces and the connecting piece supporting plate from top to bottom and are screwed into the top of the external frame, a mullion frame is further fixedly arranged at thetop of the connecting piece supporting plate, four mullion frame fixing screws are fixedly and symmetrically embedded into the two sides of the mullion frame through threads, and four ends of the mullion frame are embedded into the left sides and the right sides of the two sets of connecting pieces correspondingly. According to the external connecting piece, when the structure is assembled, the mullion frame fixing screws slide up and down on one side of the slope on the inner side of the connecting piece to drive the mullion frame to slide down slowly and be pressed tightly, the mullion framedoes not need to be pressed downwards with force all the time to align mounting holes during mounting, and mounting is easier and more labor-saving.

Description

technical field [0001] The invention relates to the technical field of door and window accessories, in particular to an external connecting piece suitable for the connection of aluminum alloy door and window mullions. 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 the base material of the force-bearing rod (the rod that bears and transmits its own weight and load), and wood and 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 From the selection of raw materials (aluminum profiles), the surface treatment of aluminum materials, the quality of in...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an external connector suitable for the connection of aluminum alloy door and window stiles, so as to solve the problem that the existing door and window sill connectors proposed in the background technology often provide mounting holes on the stile frame during assembly. When installing, it is necessary to align the mounting holes on the stile frame with the mounting holes on the connector, and in order to improve the firmness of the installation, it is often necessary to press the stile frame hard to align the two mounting holes, which is very laborious during installation, and these Most of the connecting holes and bolts are exposed on the outside, and the joints are also directly exposed, so rainwater can easily seep into the interior, causing corrosion of internal parts
