周知であるから、ここでの詳説は省略する。Embodiments of the present invention will be described below with reference to the drawings. FIG. 4 is a side view of the high-pressure cleaning gun according to the present invention, in which the high-pressure cleaning gun has a grip 1 at the rear end of a lance 10 through which cleaning water can pass.
2. The nozzle body 14 is attached to the tip. A wash water inlet 16 is formed near the grip 12 of the lance 10, and a wash water supply hose 18 is connected to this. A lever 20 is provided in front of the grip 12, and when the lever 20 is pulled, cleaning water is supplied to the lance 10. Since these configurations are already known, detailed description thereof is omitted here.

うにしたものである。A nozzle 22 is attached to the nozzle body 14, but in the present invention, the nozzle 22 is a rotating mechanism 24.
By this, it is possible to rotate at any angle in the ejection surface and fix it at that position. 1 to 3 are cross-sectional views of the nozzle body 14 showing a specific example of the rotating mechanism 24, but in this example, the nozzle mounting body 26 in which the nozzle 22 is erected in the radial direction is freely rotatable in the nozzle body 14. The pinion 28 is attached to the nozzle mounting body 26, and the pinion 28 is rotated by pushing and pulling the rack 30.

たアウタ受け３８と把持杆３４で受けているのである。In this case, since it is a condition that the rotating mechanism 24 can be operated at hand, in this example, the operation wire 32 is connected to the rack 30, and the operation wire 32 is connected to the lance 10.
The gripping rod 34 provided near the grip 12 can be operated. That is, the inner wire 32a of the operation wire 32 is connected to the rack 36 and the lever 36 provided on the grip rod 34, and the outer cable 32b is received by the outer receiver 38 and the grip rod 34 provided on the nozzle body 14 side.

易である。Thus, if the lever 36 of the grip rod 34 is pulled by hand (by the way, the grip 12 is held by the right hand, the grip rod 3
4 will be held with the left hand), the rack 30 is also pulled and the pinion 28 moves, and the nozzle mounting body 26,
That is, the direction of the nozzle 22 is also different. Note that the angle of the nozzle 22 is fixed by setting the pulling margin of the lever 36. By the way, at this time, the rack 30 is attached to the spring 40.
If the lever 30 is always urged to one side, the rack 30 automatically returns to its original position when the hand is released from the lever 36, so that the operation is easy.

らないというものではない。Next, the above nozzle 22 is the nozzle mounting body 2
It is also conceivable that two injection patterns are provided at both ends of the nozzle 6, one of them being a direct type and the other being a fan type. In this case, it is also conceivable to insert a switching ball 44 in the cleaning water supply passage 42 in the nozzle mounting body 26 so that the nozzle 22 from which the cleaning water is sprayed can be selected in the tilting direction. Further, the mounting angle (phase) of the nozzle 22 mounted on the nozzle mounting body 26 may be different for each. In either case, this is not necessarily the case, although it is for obtaining an efficient cleaning action.

回転すれば十分である。On the other hand, it is preferable that the rotation angle of the nozzle mounting body 26 is large, but if the rotation angle is too large, the structure becomes complicated and the size becomes large. Therefore, in the present invention, the range of about 90 ° is sufficient. This is because if it rotates to this extent, it will face almost all directions. In particular, if a plurality of nozzles 22 are attached while changing their attachment angles, it is sufficient to rotate this angle.

ればならないというものではない。In addition to this, since the position of the grip rod 34 and the outer receiver 38 must be adjusted on the lance 10, this is done by the setscrews 46 and 48, respectively. Of these, the set screw 48 on the gripping rod 34 side can also serve as a grip for gripping the gripping rod 34. On the other hand, since the flow rate of the wash water supplied to the lance 10 must be adjustable, this is performed by the well-known flow rate adjusting valve 50, but it is also possible to use this flow rate adjusting valve 50 and the above-mentioned grip. . Of course, this is an example, and it is not always necessary to do so.

せることができる。With the above-mentioned structure, the nozzle is brought close to the portion to be washed, the lever is pulled, and the washing water is jetted from the nozzle to perform the washing. At this time, if there is a spot such as a blind spot and sufficient cleaning water cannot be sprayed at a normal nozzle angle, the lever of the gripping rod is pulled to change the direction of the nozzle. Of course, at this time, the lance can be rotated about its axis within a range of 360 °, so that by performing both of these operations, the cleaning water can be sprayed in all angles and directions.

Although an example in which the pinion is used and this is operated by the operation wire is shown, in addition to this, a bevel gear mechanism may be adopted and operated by a rod. Further, although two nozzles may be attached in some cases, more nozzles, for example, three or more nozzles may be attached.

That is, the nozzle for jetting the cleaning water can be rotated at an arbitrary angle within the jetting surface and fixed at that position, and its operation can be performed. The cleaning water can be sprayed in all directions during the cleaning work, and cleaning with a strong cleaning effect can be efficiently performed.
