As described in the prior art, when the hanging connection tube of the water collector and the receiving tube of the elbow are both rectangular, they cannot rotate while connected and the direction of the elbow cannot be changed. is there. Therefore, there is a problem that the adjustment of the direction is troublesome.

The present invention has been made in view of the above problems of the conventional technology, and the purpose thereof is to connect the direction of the elbow while connecting the rectangular hanging connection tube and the receiving section of the rectangular elbow. It can be easily adjusted.

[Means for Solving the Problems]

The connection structure of the water collector and the elbow of the present invention forms a rectangular hanging connection tube at the bottom of the water collector body, and a lower end of the tube body is bent inward and the rising spring piece rises further upward. Is formed to connect the rising spring piece and a part of the lower end of the cylindrical body in a substantially U-shape, and at the same time, the rising spring piece is formed with a locking step portion projecting toward the inside of the cylindrical body. The upper end is bent in the direction of the wall of the cylinder and inserted through the through wall hole of the cylinder so that it can be pulled out freely and the rising spring piece is made to face the inner surface of the cylinder to form the outer cylinder. An insertion gap is formed on the outer side of the drooping connection cylinder with the outer peripheral surface of the square drooping connection cylinder to be fixed to form a water collector, while the square insertion receiving cylinder portion is formed at one end and the square insertion An elbow is formed by forming a locking projection on the outer surface of the receiving cylinder, and inserting the rectangular insertion receiving cylinder of the elbow into the insertion gap between the rectangular hanging connection cylinder of the water collector and the outer cylinder. The locking projection is made in allowed engaging the locking stepped portion of the startup spring piece of the outer cylinder of the catchment unit.

〔Example〕

1 and 2, A is a water collector and B is an elbow.

The water collector A is formed by forming a rectangular hanging connection cylinder 2 at the bottom of the water collecting body 1 and fixing an outer cylinder 3 to the outside of the rectangular hanging connection cylinder 2. The outer cylinder 3 has a lower end part of the cylindrical body 4 bent inward to form a rising spring piece 5 which rises further upward, and the rising spring piece 5 and a lower end part of the cylindrical body 4 are substantially U-shaped. It is continuous like a letter. Further, the rising spring piece 5 is formed with a locking step 6 projecting inwardly of the cylinder body 4, and the upper end portion of the rising spring piece 5 is bent toward the wall of the cylinder body 4. The operating piece 7 is inserted into the through wall hole 8 of the cylindrical body 4 of the outer cylinder 3 so as to be freely drawn out, and the rising spring piece 5 is opposed to the inner surface of the cylindrical body 4. An insertion gap 9 is formed between the rectangular hanging connection cylinder 2 and the outer cylinder 3.

The elbow B has a square insertion receiving cylinder portion 10 formed at one end, and a locking projection 11 is formed on the outer surface of the end of the square insertion receiving cylinder portion 10.

The water collector A and the elbow B are connected as shown in FIGS. 3 and 4.

That is, the rectangular insertion receiving cylinder portion 10 of the elbow B is inserted into the insertion gap 9 between the rectangular hanging connection cylinder 2 and the outer cylinder 3 of the water collector A. In this case, the locking step 6 of the rising spring piece 5 of the outer cylinder 3 and the elbow B
The position of the locking stepped portion 11 formed on the outer surface of the end of the rectangular insertion receiving cylinder portion 10 is the same, and when the square insertion receiving cylinder portion 10 is inserted into the insertion gap 9, The hanging connection tube 2 enters the rectangular insertion receiving tube portion 10, and the locking projection 11 of the rectangular insertion receiving tube portion 10 presses the locking step portion 6 of the rising spring piece 5. Since the locking step portion 6 is formed on the rising spring piece 5, when the locking step portion 6 is pressed, it moves outward, and when the locking step portion 11 goes above the locking step portion 6. The locking step 6 is returned to the original position by the spring property of the rising spring piece 5, the locking projection 11 is locked to the locking step 6, and the water collector A and the elbow B are connected. become.

When it is necessary to change the direction of the elbow B after connecting the water collector A and the elbow B, the operation piece 7 is pulled. Since the operating piece 7 is formed by bending the upper end portion of the rising spring piece 5 of the water collector A toward the wall of the tubular body 4, when the operating piece 7 is pulled, the rising spring piece 5 has its spring property. Move outward by the locking step 6
The elbow B is disengaged from the water collector A. In this case, the entire portion where the rising spring piece 5 and a part of the lower end of the cylindrical body 4 are continuous in a substantially U shape can be deformed in a large range, so that the stress due to the deformation is hard to concentrate and the durability of the same portion is improved. In addition, the operating piece 7 can be easily pulled with a small force, and since the rising spring piece 5 is opposed to the inner surface of the cylindrical body 4, the operating piece 7 is inserted through the through hole 8 When it is pulled out, the start-up spring piece 5 comes into contact with the inner surface of the cylindrical body 4 and the operation piece 7 is prevented from being pulled too much, so that the operation piece 7 and the start-up spring piece 5 are deformed too much and damaged. To be prevented. After detaching, the elbow B can be connected in an appropriate direction by changing the angle and connecting the elbow B to the water collector A again.

〔effect〕

As described above, the connection structure between the water collector and the elbow of the present invention is
Even if the elbow is square and cannot be rotated, it can be easily attached and detached, and the direction of the elbow can be changed to adjust it in an appropriate direction.

Further, in the structure for connecting the water collector and the elbow, the elbow can be detached and cleaned even when dust or the like is clogged in the connection portion. Moreover, when the operating piece is pulled to unlock the locking step and the locking projection, the entire portion where the rising spring piece and a part of the lower end of the tubular body are substantially U-shaped is deformed in a large range. Therefore, the stress due to the deformation is less likely to concentrate, and the durability of the portion is improved. Moreover, the operating piece can be easily pulled with a small force, and the rising spring piece has the inner surface of the cylindrical body. When the operation piece is pulled out from the through wall hole, the start-up spring piece stops against the inner surface of the tubular body, and the operation piece and the start-up spring piece are prevented from being pulled too much. Damage due to over-deformation is prevented.
