A connection structure and connection nut between a door and window transfer frame and a fixed frame

Abstract

Disclosed are a connecting structure and connecting nuts of a door and window through connection frame and a door and window fixed frame. The connecting structure comprises a connecting piece. The connecting piece comprises a flat batten-shaped fastening plate. Hook ribs are arranged on the face of the fastening plate in the longitudinal direction to form groove-shaped clamping positions. The fastening plate of the connecting piece is fixedly arranged on one outer wall of the fixed frame. The side wall, connected with the fixed frame, of the through connection frame is provide with hook pins, and the hook pins are embedded into the groove-shaped clamping positions of the connecting piece and are fastened. The side wall, connected with the fixed frame, of the through connection frame is provided with through holes in advance to embed nuts. The nuts and the hook ribs are arranged in a crossed mode in the longitudinal direction of the connecting piece. One end face of each nut body is connected with a convex blocking sheet perpendicular to the axial direction of the nut body. The convex blocking sheets are connected into the hook pins of the through connection frame in a clamped mode. A fastening screw is screwed into an internal thread through hole of each nut. The tail end of each fastening screw is abutted against the fixed frame. The connecting structure is convenient and fast to install and capable of being flexibly adjusted, therefore, defective products are reduced, production efficiency is greatly improved, and economic benefits are improved.

Description

technical field [0001] The invention relates to door and window profiles, in particular to a connection structure and a connection nut between a door and window transfer frame and a fixed frame. Background technique [0002] For some existing aluminum alloy doors and windows, due to the particularity of the structure and profiles, for example, in order to adapt to different types of profiles and combine with different types of profiles, it is often necessary to install a transfer frame between the main profiles. For example: by installing an adapter frame, some windows that can only be installed with fixed fans can be converted into windows that can be opened. This is fixed-to-open; This is turn on turn fixed. At present, the connection method between the aluminum alloy door and window transition frame and the fixed frame is realized by screwing through the two profiles, and finally tightening the screws. This method is likely to cause the sliding teeth of the screw holes ...

AI Technical Summary

Problems solved by technology

This method is likely to cause the sliding teeth of the screw holes of the profile, and the screws cannot be tightened, so that the door and window fixing frame and the transfer frame cannot be firmly connected, thereby posing safety hazards; secondly, this method cannot control the overlapping of the door and window fixing frame and the transfer frame. Intake

When the size of the door and window transfer frame is too small, the matching gap between the transfer frame and the door and window fixing frame will be too large. With the existing screw connection method, it is difficult to ensure that the four-side lap gap between the transfer frame and the door and window fixing frame is even. In the case of uneven overlapping, either directly scrap and redo the transfer frame, or barely accept defective products
