After removing the nut and disassembling the door lock, insert it into the vertical arm 1 up to the inner curved part 10 of the door lock body 2, and in this state insert the bolt 4 of one long ring-shaped lock body 5 into the through hole 3. The other chain body 5 must be fastened with the nut 4a via the through spring 6, and the two lock bodies 5, 5 must be integrated again.

Furthermore, in order to fix the door lock body 2 to the vertical beam 1 of the pipe door A, it is necessary to tighten a pair of bolts and nuts 7, 7a.

In this way, conventional door locks for pipe doors require all parts to be disassembled once at the construction site of the house, which is extremely difficult to work with due to the conditions at the work site, and there are many accidents such as loss of parts. There was a problem.

The present invention has been made in view of the above circumstances, and aims to provide a door lock for a pipe door that has a simple structure, can be attached to the pipe door A very easily, and can be securely fixed. The purpose is

[Means for solving problems]

In order to achieve the above object, the present invention, in a door lock for a pipe door installed on the gable side of a greenhouse, has a main body made of a thin steel plate having a U-shaped cross section, and a central part of both outer sides of the main body. A pair of locking bodies are rotatably connected together via a polygonal bolt, and the U
The open end edges of the character-shaped main body are each folded inward to form a locking edge, a wedge piece is removably fitted to the locking edge, and the vertical beam of the pipe door is connected to the wedge piece and the polygonal bolt. It is characterized by being clamped between the two using elastic force.

[Function] Next, to explain the function of the present invention, at a house construction site, the door lock is inserted into the vertical beam of a pipe door that is installed to be openable and closable from the opening on one side of the door lock, and the open end of the main body is folded back. The wedge piece is driven into the locking edge by engaging the bent edges of both sides of the wedge piece and sliding it.

When the wedge piece is locked to the door lock body in this way, the vertical lever of the pipe door comes into contact with the hexagonal bolt, and when the lock body is rotated, the hexagonal bolt is also rotated and the wedge piece is clamped. The elastic force of the piece allows the locking body to be reliably held in its stopped position.
