Corner connector for movable connection

Abstract

The invention discloses a corner connector for movable connection, which comprises a corner connector matrix mounted on a main window frame and a side window frame, wherein the corner connector matrix comprises a main connecting part and a side connecting part, a regulating part for regulating tightness and a fixing part are arranged at the joint of the main connecting part and the side connecting part, the main connecting part and the side connecting part are provided with a main mounting groove and a side mounting groove respectively, the regulating part sequentially penetrates the main mounting groove, the main connecting part, the side connecting part and the side mounting groove respectively, the regulating part and the fixing part are matched and mounted, locking parts for locking the main window frame and the side window frame are arranged on the main connecting part and the side connecting part respectively, the connection is firmer, the loading and the unloading are simple, the tightness between the main connecting part and the side connecting part is regulated, the adjustment is flexible and convenient, dimension errors between the main window frame and the side window frame during actual applications are effectively overcome, the using quality is ensured, the unnecessary loss is prevented, the service life is effectively prolonged, and the manufacturing cost is greatly reduced.

Description

technical field [0001] The patent of the present invention relates to a connecting corner bracket for assembling the corners of aluminum alloy door and window frames, in particular to a movable connecting corner bracket, which is widely applicable to connecting devices for assembling various aluminum alloy door and window frames. Background technique [0002] At present, most of the corner bracket bases assemble the corners of the horizontal bracket and the side bracket to form a door and window frame. Most of the corner bracket bases are composed of a whole piece of metal or plastic. Although the structure of the corner bracket base is simple , but the aluminum alloy window frames of the corresponding horizontal brackets and side brackets are complicated to manufacture, thereby greatly reducing the working efficiency of corner assembly and causing high costs.

AI Technical Summary

Problems solved by technology

[0002] At present, most of the corner bracket bases assemble the corners of the horizontal bracket and the side bracket to form a door and window frame. Most of the corner bracket bases are composed of a whole piece of metal or plastic. Although the structure of the corner bracket base is simple , but the aluminum alloy window frames of the corresponding horizontal brackets and side brackets are complicated to manufacture, which greatly reduces the work efficiency of corner assembly and results in high costs

[0003] However, there are some aluminum alloy window frame sash corner assembly corner bracket bases on the market now. The corner bracket bases are connected by pressing. It is difficult to repair after the corner, so the assembler adds wooden or plastic fixing parts to the corner bracket base. The outer edge of the aluminum-gold window frame of the side bracket extends to the base of the corner bracket, and the bolts are matched and locked with the fixing parts, so that the base of the bracket is fixedly installed on the horizontal bracket and the side bracket

However, the fixing part is a wooden block, which is prone to dampness, mildew, thermal expansion and contraction due to the influence of the weather, and is difficult to fix, which seriously affects the quality of the product and reduces the service life; During installation or use, excessive force will damage the fixing parts, which will easily loosen the connection of the decoding base, which also seriously affects the service life, and it is extremely inconvenient to disassemble and easily damage the quality of the product.

[0004] And, in the actual assembly process, there will be errors in the dimensions of the connection between the horizontal bracket and the side brackets, but it is difficult to adjust the dimensional errors between the horizontal brackets and the side brackets, resulting in unnecessary losses
