A combination door pocket

Abstract

The invention discloses a combined door pocket comprising a first door pocket body, a second door pocket body and a guide rail arranged horizontally along the thickness of a wall. The first door pocket body comprises a first exterior trimming portion arranged along the inner wall of the wall and a first extension portion inserted on the guide rail, the second door pocket body comprises a second exterior trimming portion arranged along the outer wall of the wall and a second extension portion arranged along the thickness of the wall, the first extension portion bends towards the wall to form a first connecting portion, the second extension portion bends in a manner of being away from the wall to form a second connecting portion, the first connecting portion and the second connecting portion are located between a door body and the guide rail and connected with the guide rail through a connecting part. A protrusion portion facing towards the direction of the door body is arranged on the first connecting portion, and the outer side face of the protrusion portion and the outer side face of the first extension portion are coplanar. The first connecting portion, the second connecting portion and the connecting part are located in a groove formed between the protrusion portion and the second extension portion, and a sealing part is arranged in the groove. The guide rail is connected with the wall through a washer and bolts.

Description

technical field [0001] The invention relates to a combined door cover, which belongs to the field of door cover profiles. Background technique [0002] At present, the construction of most of the door covers is carried out after on-site surveys. The plates are first calculated, laid out, sawed, and planed into materials, and then installed on the wall layer by layer. Finally, the front and side joints and hemming are completed. . This integrated construction method is slow and destructive to the environment; and the bonding position is prone to problems such as cracks and ply shedding, which will affect the use and appearance of the door cover. [0003] In order to solve the problems of slow construction speed, strong damage to the environment, and easy cracking of the adhesive part of the door cover in the prior art, Chinese patent document CN1614185A discloses a combined door cover, which includes a fixed frame and a movable frame. Wherein the fixed frame is fixed on the...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the connection between the positioning pin and the sub-slot in the prior art is not firm, and the movable frame is easily separated from the fixed frame due to external force; furthermore, a combined door pocket with firm connection is proposed

[0007] Another technical problem to be solved by the present invention is that when the thickness of the wall changes in a small range in the prior art, it is necessary to remake the combined door cover to ensure that the movable frame and the fixed frame are firmly connected, and at the same time, the connection between the positioning pin and the sub-groove is The method has high requirements on the processing accuracy of the door cover and is difficult to process; and then proposes a combined door cover that is suitable for walls with small-scale changes in thickness and is easy to process
