Description

[Detailed Description of the Invention] The present invention relates to a connection structure between a gutter water collector and a square tube elbow.

Conventionally, in order to connect a rectangular tube gutter to a water collector with a drainage cylinder, an elbow, etc., whose upper part is cylindrical and the lower part is a rectangular tube, is glued to the drainage cylinder and the rectangular tube gutter. However, in such a structure, the direction of the elbow glued to the drainage cylinder cannot be changed or removed, which is very inconvenient during construction and after construction.

The present invention solves the above-mentioned conventional drawbacks and provides a connection structure between a gutter water collector and a rectangular tube elbow, which allows the drainage cylinder and the rectangular tube gutter to be freely attached and detached, and also allows the direction of the rectangular tube gutter to be freely changed. That is.

Next, embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 designates a connecting ring, in which locking pieces 21, 21, . Support step portion 2 formed to have a shape
Support recesses 23, 23, . . . are provided approximately in the center of 2, 22, .
are placed opposite each other. Locking pieces 21, 21,
... are provided at approximately equal intervals, and support recesses 22,
22, . . . may be provided at two opposing positions.

The combination of the water collector main body 3, these connection ring 1, and the square tube elbow 5 is made by inserting the lower end of the square tube elbow 5 from above the connection ring 1.
After supporting the support pieces 51, 51, ... in the support recesses 23, 23, ... of the support steps 22, 22, ... of the connection ring 1, the water collector body 3 is inserted from above the connection ring 1.
By inserting the drainage cylinder 31 of the drain cylinder 31 and elastically fitting the locking pieces 21, 21, . Connected.

According to the connection structure of the gutter water collector and the rectangular tube elbow of the present invention, the locking protrusion provided on the upper outer wall of the drainage cylinder of the water collector body has a locking ridge extending inward at the upper end of the connecting ring. The stop piece is locked, and the support piece provided on the outer wall of the upper end of the square tube elbow is supported in the support recess of the support step formed so that the square tube elbow is inserted into the lower end of the connecting ring. The connecting ring is rotatable relative to the drainage cylinder while supporting the square tube elbow, and the direction of the square tube elbow can be changed freely, and it can be locked by applying an external force to the connecting ring to slightly deform it. The piece can be removed from the locking protrusion.
