Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sprinkling nozzle for ejecting water supplied from a hose from a nozzle head,
In particular, it relates to a device that can stop water and control the amount of water sprayed at hand.

[0002]

2. Description of the Related Art A conventional sprinkler nozzle shown in FIG. 10 has a main body E for introducing water from a water source and a head ring A.
Side head body C, and inside the head body C,
A cylinder B, which moves back and forth by gripping or releasing the handle D (in a state of a broken line), is supported by a spring I. When the handle D is gripped, the handle D and the cylinder B move in the direction of the arrow J, the tip of the cylinder B separates from the packing G, and the water passage H is formed as shown in FIG. Release handle D,
Due to the spring I, the cylinder B and the handle D move in the direction of arrow K, the tip of the cylinder B contacts the packing G, and the water passage H is closed, and the water is stopped. Handle D
When the water passage H is fully opened by gripping, the handle F can be fixed by the stopper F so as not to return, and if the stopper F is removed and the handle D is released, as described above. It can be stopped.

[0003]

However, in the water-stop state,
When trying to control the flow rate in the middle of the fully opened state of the water passage H, it is necessary to adjust the grip of the handle D, and in particular, it has been difficult to maintain the desired flow rate. Since the handle D is popped out and the main body is a pistol type, there is a problem that the nozzle takes up a space when not in use and the nozzle is caught by a tree or a wall when storing the hose and damaged. In addition, a handle or
Since a cock etc. was required, the number of parts increased and it took time to assemble. Therefore, an object of the present invention is to make it possible to easily perform a water blocking operation and a flow rate control at hand. In addition, the shape should be such that it does not get in the way when water is stopped and that it can be stored easily.

[0004]

According to a first aspect of the present invention, a main body is composed of a body main body and a head main body having a water passage formed therein, and the body main body and the head main body are connected to both the water passages. The surface where one of the water passages is opened is used as a joint surface, and the surfaces are connected so as to be rotatable relative to each other about the center of rotation in the joint surface. It is a watering nozzle that changes from. The second invention is based on the above invention, and is characterized in that when the angle formed by the body main body and the head main body is 180 °, the overlapping area of the opening surfaces of both water passage ports becomes zero.

[0005]

[Function] Since the overlapping area of the opening surfaces of both water passages changes depending on the angle formed by the body and head body, you can bend or extend the nozzle body without using a handle or cock to stop water And adjust the flow rate. When the angle between the body body and the head body is 180 °, the area where the openings of both water passages overlap is 0. In the nozzle, the nozzle body is straight when the water is stopped, so it is easy to get caught outside. It does not have any parts, and it is also easy to store.

EXAMPLE This example shown in FIGS. 1 to 9 is a body 1
And a head body 2 provided with a head ring 3 having a water spouting port, the joint surfaces 22 and 23 are joined so as to come into contact with each other in the middle, and the body body is rotated around an axis passing through the center 20 of the joint surfaces 22 and 23. By relatively rotating 1 and the head main body 2, water blocking and flow rate control are performed. Figure 1
In the body body 1 shown in FIG. 4, a water passage 9 is formed from the hose connection portion 8 to the joint surface 22 with the head body 2, and the joint surface 22 has a water passage opening 10. Further, the joint surface 22 is formed with an O-ring groove 16, a spring receiver 19, and a recess 13. 1, 2,
The head main body 2 shown in FIG. 5 and FIG. 6 has a water passage 18 that opens to the joint surface 23, a water passage 17 that follows the water passage 18, and a ball receiver 2
1a to 21e are formed. The water passage 17 communicates with the head ring 3, and the ball receivers 21a to 21e are formed at positions whose central angles rotate by 15 °.

Joining surface 22 of body 1 and head 2
And 23 together, and tightening screw 7 passed through screw hole 5
And the tightening nut 6 to join. Then, the body 1 and the head body 2 are centered on the center point 20,
Although it is relatively rotatable, the convex portion 4 of the joint portion 23 fits into the concave portion 13 of the joint surface 22, so that it can rotate within the range of the concave portion 13. As the ball 11 of the ball spring 12 rotates relative to the body body 1 and the head body 2, the ball receivers 21a to 21e.
To move. In this embodiment, every 15 ° rotation,
Since it is possible to move the ball receivers 21a to 21e and maintain the state, it is possible to maintain a constant amount of water spray controlled in stages. 7-9, the joint surface 22 and 2
3 shows a joint portion between the body 1 and the head body 2 in a state where 3 is overlapped. FIG. 7 shows the water inlet 10 and the water inlet 1.
When the overlapping area S of 8 is the maximum, the angle ω formed by the body 1 and the head 2 is the same as in the state shown in FIG.
Is 120 °, and the ball 19 is received by the ball receiver 21a. This state is a pistol type in which the amount of water is maximum and water is easily sprinkled when gripping the body 1 and spraying water.

From this state, when the head body 2 is separated from the body body 1 and the angle ω is increased, ω = 120 °
At + 15 °, as shown in FIG. 8, the ball 19 is received by the ball receiver 21b, and the area S is slightly reduced. That is,
Sprinkling volume is reduced. Similarly, extend the bend of the body,
Is increased by 15 °, the position of the ball receiver for receiving the ball 19 moves from 21c to 21e, and the amount of water spray decreases corresponding to the area S. As shown in FIG. 9, ω = 180
When the main bodies 1 and 2 are straight, the water passages 10 and 18 have no overlap and are in a water-stop state. In this way, when the water is stopped, if it is a straight line, it will not get caught here and there and will not be damaged when winding up the connected hose around the reel, and it does not take up much space during storage. . Unlike the present embodiment, even if it does not become a straight line when the water is stopped, there is no difference in that the water amount can be easily controlled at hand, and if the hose is removed, if it can be made a straight line. It also has a high storage capacity.

[0009]

According to the present invention, the water blocking operation and the flow rate control can be easily performed by hand by adjusting the bending angle of the nozzle during water sprinkling. When water is stopped, it does not get in the way, does not get caught by other objects and is damaged, and it can be made into a shape that can be stored easily. Further, the one provided with a mechanism for fixing at a constant angle during watering can maintain a constant watering amount. Furthermore, since no handle or cock is used, the number of parts is small and assembly is easy.
