Abstract

The utility model relates to a cylindrical water spray pistol, particularly a cylindrical water spray pistol used for flushing in the occasions of building ground and water spraying and flushing, garden irrigation, and traffic vehicle, comprising a cylinder outer shell, a cylindrical internal sleeve and a valve core. The outer shell and the internal sleeve are connected with screws, and the valve core with a flat gasket is arranged between the water spray opening and the internal sleeve and is tightly fixed through the round tube of the internal sleeve with nuts; a sealed ring is arranged between the outer shell and the internal sleeve, and the lower end of the cavity of the internal sleeve is provided with a pipe thread and a cushion ring. The inner side of the circumference of the water spraying opening is provided with a notch, and the gap size between the valve core and the water spraying opening is regulated by the internal sleeve which rotates in the clockwise direction; the utility model can eject the cylindrical water column and the mushroom-shaped lipper, and the internal sleeve which rotates in the counterclockwise direction closes a water spraying gun.

Description

Cylindrical water spray pistol

The utility model relates to a kind of column type water pistol, especially the column type water pistol of the flushing usefulness of construction site hydroblasting occasion, gardens pouring, vehicular traffic.

At present, on the construction site stone flushing, component conservation, cleaning wash away, the flushing work of the pouring of the flowers in the gardens and vehicular traffic, all adopt outmoded method: with plastics or rubber flexible pipe, the one end is enclosed within on the water tap, and its other end pinches with hand, change the bore of flexible pipe delivery port with the power of pinching of hand, to adjust water flow velocity, this method is obviously operated inconvenience, and labour intensity is big, the delivery port valveless can not in time be closed, and water resource waste is serious.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, and provide a kind of spray cylindrical water column or mushroom-shaped spray, both can make the column type water pistol that the current valve can adjust water flow velocity.

Task of the present utility model is finished by following technical measures.

One cylinder blanket ［ 4 ］ (seeing Fig. 1,2,3), its water jet ［ 10 ］ inside circumference is provided with recess ［ 101 ］, cavity wall is provided with screw thread ［ 43 ］ in it, and its outside is provided with T-slot ［ 41 ］ and shake hands ［ 42 ］, places rubber bumper ring ［ 1 ］ in the T-slot ［ 41 ］.Shake hands ［ 42 ］ be convenient to control.Rubber bumper ring ［ 1 ］ can guarantee that water pistol is not got rid of bad because of at will throwing out quilt without care.

One cylindrical interior cover ［ 6 ］ (seeing Figure 4 and 5), its outer wall is provided with screw thread ［ 43 ］ and is threaded with cylinder blanket ［ 4 ］.

One pipe ［ 61 ］ is overlapped on cylindrical interior cover ［ 6 ］ inner chamber (see figure 5) that goes up suitable for reading.

One spool ［ 2 ］ (see figure 1) place between water jet ［ 10 ］ and the interior cover ［ 6 ］ and went here and there in the cover ［ 6 ］ pipe ［ 61 ］ with nut ［ 7 ］ fastening.Spool ［ 2 ］ is gone up an affixed plain washer ［ 9 ］.

Cover ［ 6 ］ is provided with groove ［ 31 and 51 ］ in cylindrical, wherein places O-ring seals ［ 3 and 5 ］ respectively, for cylinder blanket ［ 4 ］ and cylindrical interior cover ［ 6 ］ assembling back keep good sealing.

Cover ［ 6 ］ inner chamber lower end is provided with gas thread ［ 63 ］ and packing ring ［ 8 ］ in cylindrical, so that seal with guaranteeing interface after the flexible duct joint is connected.

The explanation of accompanying drawing drawing:

Fig. 1 is the utility model structural representation.

Fig. 2 is the cylinder blanket cutaway view.

Fig. 3 is the vertical view of Fig. 2.

Fig. 4 is cylindrical interior cover cutaway view.

Fig. 5 is the vertical view of Fig. 4.

During use, running water is through water-supply-pipe enters column type water pistol cylindrical by the flexible duct male connection in behind the cover ［ 6 ］, directly enter in the cavity between cylindrical shell ［ 4 ］ and the cylindrical interior cover ［ 6 ］, by cover ［ 6 ］ in the slewing circle cylindricality, produce between interior cover ［ 6 ］ and the shell ［ 4 ］ and relatively move, in the face of the inlet end interior cover ［ 6 ］ that turns clockwise, interior cover ［ 6 ］ drives spools ［ 2 ］ and moves, spool ［ 2 ］ increases with water jet ［ 10 ］ gap, water penetrates from water jet ［ 10 ］, gap between spool ［ 2 ］ and the water jet ［ 10 ］ hour, water penetrates from the cylindrical water column of water jet ［ 10 ］.When the gap between spool ［ 2 ］ and the water jet ［ 10 ］ was big, water was the ejection of mushroom spray from the recess ［ 101 ］ of water jet ［ 10 ］.When needs are closed water pistol, counterclockwise overlap ［ 6 ］ in the rotation, till screwing, spool ［ 2 ］ is tightly pushed down water jet ［ 10 ］, and water pistol promptly is closed.

The utility model compared with prior art has following advantages: 1, reduces labor intensity, and easy to operate. 2, using water wisely. 3, multipurpose satisfies the needs of various hydroblasting occasions. 4, the raising site environment of carrying out production strictly in line with rules and regulations is played highly effective effect.
