Description

CONNECTING DEVICE OF DOOR FRAME < RTI ID = 0.0 >

The present invention relates to a connection structure of a door frame in which two horizontal frames horizontally parallel to each other and two vertical frames parallel to each other are perpendicularly connected to each other, Of the door frame so that the coupling can be quickly coupled to both sides of the vertical frame to enable the joining operation to be carried out conveniently by an expert, Structure.

In general, a connection structure of a conventional door frame is disclosed in Korean Registered Patent Application No. 10-1447217, in which a connecting member is coupled to both sides of a horizontal frame, and the connecting member is coupled to both sides of a vertical frame .

In this case, since the connecting member is formed in a straight line, it is difficult to match the holes of the fastening piece formed in the horizontal frame with the fastening piece hole formed in the connecting member when the fastening piece is coupled to both sides of the horizontal frame. The upper and lower portions of the connecting member are coupled to the horizontal frame. In a state where the upper and lower portions of the connecting member are coupled with each other, the fastening pieces are loosened, There is a problem in that it is troublesome in operation that the connecting member should be coupled to both sides of the horizontal frame with the fastening piece.

Further, when the connecting member is loosely coupled or obliquely coupled to the horizontal frame, there is a problem that the guide groove formed between the connecting member and the horizontal frame and the guide protrusion of the vertical frame do not coincide with each other.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a connector for a connector, So that it is possible to carry out a joining operation conveniently with not only an expert but also an unskilled person.
