Description

Pneumatic multi purpose automatic water injecting gun

A kind of Pneumatic multi purpose automatic water injecting gun belongs to the water gun field.

Existing water injecting gun pressure water piston type is as " powerful water pistol " (application number CN87208056) of Patent Office of the People's Republic of China's bulletin on December 31st, 1987; Spring is as Russian Patent (SU1296-825-A); Driven by power formula such as United States Patent (USP) (US4750-641-A).The current of setting-out piston type water injecting gun can not be continuous, and it is easy to wear to pull plate machine effort and piston, influences its service life.The complex structure of spring uses inconvenience.Though the driven by power formula has realized functions such as continuous jetting, structure is more complicated, and manufacturing cost and use cost are all very high, is not easy to promote.

The present invention is just in order to overcome the above-mentioned deficiency of existing water injecting gun, adopted the power source of air pressure as jetting, creationary system has been carried out in aspects such as lance body structure, aerating device, jetting controlling organization and water flooding regime to be improved, make the water injecting gun of manufacturing out have automatically jetting, far firing range continuously, can simulate various true automatic weapons and carry out shooting functions such as single-shot, fixed fire, running fire or injection.

The object of the present invention is achieved like this.The present invention includes the rifle body of closed structure, built-in inflator, jetting controlling organization and water injection valve.The rifle body is made up of gun stock, the body of a gun, cartridge clip and the small of the stock, and the effect of rifle body is to be used for storing water and setting-out energy and other parts are installed.There is a passage to communicate on the rifle body cartridge clip, the automatic supply of the water when guaranteeing jetting in the rifle body with the small of the stock.Inflator is the axle center with the outlet pipe, and muzzle cup is a handle, and gun barrel is the tubular push rod, and leather cup is fixed on an end of gun barrel with plug screw, adopts the lip-type packing sealing between plug screw and the outlet pipe, and its cooperation should guarantee close air tight and not hinder push rod be the reciprocating motion of gun barrel.Between air cylinder body bottom centre hole and the outlet pipe with lip-type packing sealing, should be able to guarantee that gas in the inflator can be discharged in the rifle body and water in the rifle body or air-flow less than in the inflator.Air cylinder body was realized with being connected by gland of rifle body.Gun barrel (being the tubular push rod) can extend and can shorten, and built-in inflator structure can be used for multiple rifle shape.The jetting controlling organization is by guiding valve and going into, and the outlet pipe system forms, and guiding valve is four two current process control valves.Guiding valve by spool, valve seat be fixed on small of the stock top and with the plate machine on same horizontal line.The oral siphon interface of valve base inner wall has a cannelure.Fit clearance between spool and the valve seat requires to be convenient to slide not leak again.One through hole is arranged on the spool, and an end of this through hole is tightly being inserted the hollow push rod of plate machine, and the other end is equipped with spring, and spring withstands on the end face of valve seat bottom.Also have a cannelure on the outer garden of spool, this cannelure communicates with valve core through hole by relief hole.Oral siphon is connected with valve seat with two exit branch.Two water outlet arms are with in an outlet pipe, and gim peg is fixed on outlet pipe in the rifle body.Water injection valve is made up of valve body and sebific duct, and valve body is by being threaded on the rifle body, and the junction seals with rubber cushion.One taper water filling port is arranged on the water injection valve, and the cavity in the valve body is the energy dissipating chamber, has around the energy dissipating chamber to lead to the outer earial drainage aperture of valve body, is with sebific duct on the valve body wall.During water filling, water filling port can be enclosed within on the tap, running water flows into the energy dissipating chamber through water filling port, slow down the impact of water through the energy dissipating chamber after, enter discharge orifice, back down sebific duct and enter the rifle body.After running water entered the rifle body, original air was contracted by hydraulic pressure in the rifle body, thereby forms certain pressure automatically, produced the pressure energy.In addition, also water injection valve can be screwed down directly and in the rifle body, pour water, but this mode can not be pressurizeed automatically.The present invention adopts the water injection valve water filling to pressurize automatically and with inflator inflation pressurization dual mode, makes the rifle body of hermetically-sealed construction produce the certain pressure energy, and under the manipulation of jetting controlling organization, the compressing current penetrate from outlet pipe.By pulling the plate machine, the spool of guiding valve is slided in valve seat, thereby realize the cutout of water.An overall process (making a round trip) of shooting can have four strands of current to penetrate successively, and shooting states such as single-shot, fixed fire and running fire are realized by adopting the different modes of pulling.When the outlet pipe oral area was equipped with spinning disk, the current of ejaculation were spray form, and when not adorning spinning disk, current are column.

The present invention has following advantage:

1, can be automatically jetting continuously, far firing range.With outlet pipe oral area hydraulic pressure is 10 ⁵P α liter, range can reach more than 8 meters.

2, jetting mode and fluidised form are adjustable variable, can simulate the functions such as single-shot, fixed fire, running fire and injection of true automatic weapon.

3, pressurising is convenient, to pull the plate machine laborsaving, is fit to very much children and uses.

4, simple in structure, practical.Utilize the present invention can make the almost water injecting gun with various functions of Any shape and size, the scalability of gun barrel has more increased glamour of the present invention.

5, of many uses.The present invention also can be used to water flowers, spray medicine etc. except as the toy.As the no nocuity liquid (powerful coloring agent and so on) of packing into, also can be used as weapons for self-defense.

6, long service life.Various moving component of the present invention all is that high-abrasive material is made, and is not easy to wear, also can change easily just in case worn and torn, thereby prolong service life greatly.

Embodiments of the invention are illustrated in conjunction with the accompanying drawings.

Fig. 1 is that the present invention is used for spear type water injecting gun structure chart.

Fig. 2 is that the present invention is used for short arm type water injecting gun structure chart.

Fig. 3 utilizes the principle of the invention, but built-in inflator adopts the water injecting gun schematic diagram of the inflator of existing ordinary construction.

As shown in Figure 1, the component parts of this embodiment is: gun stock (1), water filling valve body (2) energy dissipating chamber (3), sebific duct (4), water filling port (5), sealing gasket (6), discharge orifice (7), gim peg (8), lip-type packing (9), leather cup (10), plug screw (11), air cylinder body (12), gun barrel (13), gland (14), sealing gasket (15), sealing gasket (16), muzzle cup (17), effluent pipe mouth (18), spinning disk (19), outlet pipe (20), the body of a gun (21), cartridge clip (22), passage (23), plate machine (24), spool (25), relief hole (26), cannelure (27), oral siphon (28), the small of the stock (29), cannelure (30), valve seat (31), spring (32), exit branch (33), exit branch (34), lip-type packing (35).The structural principle of this embodiment and function are described in summary of the invention one joint of this specification.

As shown in Figure 2, the difference of this embodiment and Fig. 1 embodiment is not have cartridge clip and gun stock, and water injection valve (1) is not the top that is contained in the body of a gun, but is contained in the rear portion of the body of a gun, and is coaxial with gun barrel, passage (2) the UNICOM's small of the stock (3) and the body of a gun (4).
