る伸縮ライザーが提案されていない。 Telescopic risers with sprinklers attached to the tips are widely used in tea plantations, orchards, etc. because the watering position can be adjusted according to the growth of plants. For telescopic risers, the upper pipe is inserted into the lower pipe connected to the water supply source using an input terminal, and both pipes are tightened using cap nuts to prevent them from coming off, but this tightening is insufficient and the valve Due to the water hammer effect caused by the sudden opening, an accident may occur where the upper pipe jumps out from the lower pipe. For this reason, the opening operation of the valve always requires caution, and is one of the troublesome tasks in actual work. On the other hand, it is desirable to use a simple method for tightening the upper pipe to the lower pipe in order to facilitate the height adjustment work of the telescopic riser.
In addition to the ease of adjusting the height of the telescoping riser, no telescoping riser has been proposed that completely prevents the upper pipe from jumping out from the lower pipe.
それ故、この考案は、簡易な操作で高さ調整を

１８を継手本体７に固定させる。 One end of the semicircular portion 13 that is integral with the joint body 7 is a vertically spaced forked portion 14, and the other end is a vertically spaced bifurcated clamping portion 15 that extends outward.
Equipped with The bolt 16 is connected to the pin 17 in the clamping part 15.
It is supported by One end of an opening/closing member 18 forming a cylindrical portion facing the semicircular portion 13 of the joint body 7 is pivotally supported on the forked portion 14 of the joint body 7 using a stud bolt 19. A protrusion 21 with a notch 20 through which the bolt 16 is passed is formed at the other end of the opening/closing member 18 , and a protrusion 23 is formed on the inner wall of the semicircular portion 22 of the opening/closing member 18 .
will be established. The opening/closing member 18 is rotatable around the bolt 19, and the opening/closing member 18 is opened by tightening the wing nut 24 with the protruding piece 21 facing the clamping part 15 and the bolt 16 passed through the notch 20 of the protruding piece 21. It is fixed to the joint body 7.

ばよいので高さ調整作業はきわめて容易である。 As is clear from the above, the telescopic riser according to this invention has one end of the opening/closing member pivotally supported on the joint body fixed to the lower pipe, and the other end of the opening/closing member is attached to the joint body using a tightening part such as a wing nut. Since the protrusion provided on the opening/closing member is engaged with the groove of the upper pipe, the opening/closing member can be fixed to the joint body with the protrusion of the opening/closing member engaged with the groove of the upper pipe. It can be fixed. Therefore, even if there is a sudden pressure increase due to water hammer or the like, the upper pipe will not come out of the lower pipe, and the upper pipe will always be securely held in the joint. Furthermore, the height adjustment of the upper tube is
Loosen the tightening part such as the wing nut, move the protrusion of the opening/closing member away from the groove, and engage the protrusion in the groove corresponding to the desired length. Then, use the tightening part such as the wing nut to tighten the opening/closing member. The height adjustment work is extremely easy as it only needs to be fixed to the joint body.
