Door frame self-locking splicing structure

Abstract

The invention discloses a door frame self-locking splicing structure. The door frame self-locking splicing structure comprises a plurality of door frames for clamping the periphery of a door plate anda rope penetrating through the door frames in sequence; and a unidirectional self-locking module is arranged on one of the door frames and comprises a fixed end and a unidirectional sliding end, oneend of the rope is connected with the fixed end, and the other end of the rope penetrates through the unidirectional sliding end to achieve unidirectional moving. The unidirectional self-locking module enables the rope to be in a shape of converging gradually, the rope can pull the door frames to the center to be converged when penetrating through the door frames, the door frames can be convergedand attached to one another, meanwhile the rope only can move unidirectionally, and thus loosening of the door frames does not need to be worried; the internal fixing splicing mode is adopted in the scheme, and no screw hole need to be formed, so that the complex machining process is avoided, and not only is the front face of the whole door frames concise and clean, but also splicing of the wholedoor frames is easy and the production efficiency is high. The door frame self-locking splicing structure is used for the field of door window mounting.

Description

technical field [0001] The invention relates to the field of installing doors and windows, in particular to a door frame self-locking assembly structure. Background technique [0002] The existing door frames are fitted around the door panels, there are sheet metal corner brackets between two adjacent door frames, and the two ends of the sheet metal corner brackets are respectively inserted into the two door frames. Usually, the door frame is fixed on the sheet metal corner code by means of screw connection. This approach makes the surface of the door frame expose screws, which is not beautiful. Although some seals can be added at the positions of the screw holes as a shield, the effect is still not ideal. At the same time, before using screws to fix, screw holes need to be drilled at the corresponding positions on the door frame and corner brackets. At this time, it is difficult to ensure the accuracy of the hole positions. with large gaps. In order to solve these proble...

Problems solved by technology

This method exposes the screws on the surface of the door frame, which is not beautiful. Although some seals can be added to the screw holes as a cover, the effect is still not ideal.

At the same time, before using screws to fix, screw holes need to be drilled at the corresponding positions on the door frame and corner brackets. At this time, it is difficult to ensure the accuracy of the hole positions. with a large gap

In order to solve these problems, we can only spend a lot of money to hire highly skilled operators
