A nozzle portion 60 is formed at the tip side 1i\ than 9,
Further, a valve portion 61 is provided at the tip of the middle tube 55 and the tip of the outer tube 56 to open and close the opening of the outer tube 56 by rotating the outer tube 56, and a valve portion 61 is provided at the tip of the outer tube 56 to open and close the opening of the outer tube 56. A water sprinkling nozzle is known that has a trumpet-shaped part, the opening of which is closed by a perforated plate 62, and a through hole 64 formed in the center of the perforated plate 62 through which a small cylinder part 63 at the tip of the middle cylinder closely slides back and forth. Retail (see VF Kaisho 55-1164599 Publication).

Problems to be Solved by the Invention By the way, in this case, the operation for changing the watering state is performed by rotating the nozzle body 53 which is externally screwed onto the base cylinder 52, and by rotating the nozzle body 53 which is externally screwed into the nozzle body 53. 55 rotation operation, rotation of the outer cylinder 56 externally fitted into the inner cylinder 55 rjIJP1. This type of watering nozzle, which is provided at the lowest possible price, requires a large number of parts to assemble, so it is difficult for women and women who are clumsy to operate it smoothly. It had drawbacks such as high labor costs and the inability to provide it at a low price. This invention solves the above-mentioned problems, and aims to provide a water spray nozzle that can be provided at low cost and is convenient to use.

Means for Solving the Problem To achieve the above object, the present invention has a structure in which a water spray nozzle includes a base cylinder 2 having a hose connection part 1 at the base end, a grip cylinder 3, and an i adjustment operation part. 4, a nozzle body 9 with a through hole 6 in the circumferential wall 5, a tip adjustment rod portion 7 and a valve portion 8, and a closed tip, and a nozzle opening 11 through which the tip adjustment rod portion 7 of the nozzle body 9 enters and exits. The nozzle body 9 comprises a non-rotating tip cylinder 15 which has a small fI part 12 with a small fI part 12 and a valve seat 13 that comes into contact with and separates from the valve part 8, and has a water flow gap 14 between it and the nozzle body 9. It is formed so as to move back and forth based on the operation of the adjustment operation section 4.

Operation and this invention uses the above-mentioned means to connect the hose to the hose connection IP1 in the state shown in FIG. If the main body 9 is moved backward, water will be ejected from the nozzle 11 in a sharp shape, and then the nozzle main body 9
If you move it backwards as shown in figure f53, the nozzle port 12
The water recedes greatly and the water gushes out in a straight line.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A detailed description of the present invention will be given below with reference to the drawings. Reference numeral 1 denotes a hose connection part, and a base cylinder 2 having a hose connection part 1 at its base end has a grip cylinder 3, an adjustment operation part 4, and a peripheral wall 5. A nozzle body 9 with a through hole 6, a tip adjustment rod portion 7 and a valve portion 8 with a closed tip, and a small cylindrical portion 12 with a nozzle opening 11 through which the tip adjustment rod portion 7 of the nozzle body 9 enters and exits. The nozzle body 9 has a valve seat 13 that comes into contact with and separates from the valve part 8, and a non-rotating tip cylinder 15 with a water flow gap 14 between it and the nozzle body 9. It is formed to move back and forth based on the operation, but there is also a first
The relationship between the adjustment operation part 4 and the nozzle body 9 is shown in the embodiment shown in FIGS. 4 to 5. As shown in FIG. 3, f that communicates with the 12 flow section 17 and further communicates with the through hole 6.
jS3 circulation g A first gasket 20 for preventing water leakage is provided rearward of the through hole 6 and in contact with the first inner wall surface 19 of the tip tube 15, and a base tube portion 30 of the nozzle body 9 is provided.
is provided with a second gasket 22 for preventing water leakage that is in sliding contact with the inner wall 21 of f52 of the grip f23, and furthermore, a protrusion 24 is provided at the middle 0 part 23 of the nozzle body 9, and a protrusion 24 is provided in the axial direction lower than the protrusion 24. A first protrusion portion 25 is provided, and a protrusion portion 24 and a first protrusion portion 25 are provided on a first continuous cylinder 28 that is continuous with the tip f215 and provided at the rear end fjS1 rear @ cylinder 27.
A first guide groove hole 29 is provided to guide the first continuous tube 2.
A two-split sleeve 32.32 having an ML spiral groove 31 on the inner surface for guiding the protrusion 24 on the outer periphery of the sleeve 32.32 is fitted over the locking recess 33 and the locking protrusion 34, and then the sleeve 32.3
2 has an f:tS2 protrusion 35 on the outer surface in the direction of the axis 5t9,
35, and an external fitting groove 36.36 for externally fitting the second protruding portion 35.35 is provided on the inner surface.
It has been established. Therefore, by rotating 151 blade rotation*10, sleeves 32 and 32 will rotate, and sleeve 3 will further rotate.
The protrusion 24 inserted into the first spiral groove 31 moves with the rotation of 2.32, but the protrusion 24 moves fj
Since the nozzle body 9 is fitted into the guide groove hole 29 together with the S1 protrusion 25, the nozzle body 9 moves in the center direction, that is, in the front-back direction, without rotating. Also, the first rear end tube 27 and the grip tube 3
and is to be joined via the f51 adhesive part 37.

Also, as shown in FIG. 5, a hose 38 is connected to the tip tube 15.
It can also be used as a valve that can adjust the amount of water by opening the continuous hose 39 connected to the water faucet and the connecting hose 38. Furthermore, the tip frJ15 has a valve that allows water to flow from between the brush surface 40. A brush body 41 capable of ejecting water can be attached and detached via a tip screw portion 26. Moreover, since the tip cylinder 15 does not rotate, the first packing 20 and the second packing 22 are prevented from twisting, and water leakage can be prevented for a long period of time.

In addition, in the embodiment shown in FIG. 156, the relationship between the adjustment ff1i operation part 4 and the nozzle body 9 is shown. A second guide groove hole 44 that guides the protrusion 24 and the first protrusion 25 to the installation tube 43
A second adjustment rotary cylinder 45 is provided with 12 spiral grooves 48 on the inner surface for guiding the protrusion 24 on the outer periphery of the second continuous cylinder 43.
This is an externally fitted version of the i12 f! The end #J42 and the grip tube 3 are joined via the second adhesive portion 46. Further, 47 is an rjS3 adhesive part.

Effects of the Invention The present invention has the above-described configuration, and includes a base tube 2 having a hose connection portion 1 at the base end, a grip f:J3, an adjustment operation portion 4, and a through hole 6 in the peripheral side wall 5. A nozzle main body 9 having a tip adjusting rod part 7 and a valve part 8 and having a closed tip, and a small #J part 12 having a nozzle opening 11 through which the tip adjusting rod part 7 of the nozzle main body 9 enters and exits, and the valve part 8. It is equipped with a valve seat 13 that comes into contact with and separates from the nozzle body 9, and is composed of a non-rotating tip tube 15 with a water flow gap 14 between it and the nozzle body 9, and the nozzle body 9 moves back and forth based on the operation of the adjustment operation ff1s4. By connecting a continuous hose from a water faucet or the like to the hose connection part 1 and pumping water through the hose, the user can operate the adjustment operation part 4 by using the grip tube 3. It is possible to maintain a constant amount of water ejected from the Zururo 11 at a desired position. In addition, the change in the jetting state and the outflow state can be controlled by operating the adjusting operation unit 4 to move the nozzle body 9 back and forth [with only hyper-motion, it can be changed into a drilled shape, straight shape, etc.
In addition, it can be stopped and changed, making the operation extremely simple. In addition, the number of manufacturing parts and labor costs can be reduced, and the product can be provided at low cost.

Furthermore, the structure is simple, there is little risk of failure, and it can be manufactured easily, which provides many industrial effects.
