Abstract

The utility model relates to a low-pressure toy water gun, which comprises a gun body, a handle formed on the gun body, a moving trigger matched on a handle position, a water tank fixed on the gun body and a piston cylinder fixed in the gun body, wherein a water outlet pipe led out from the water tank is connected to the piston cylinder connected with an ejecting tube. Springs are clipped between a piston in the piston cylinder and the piston cylinder. A piston rod connected with the piston is fixed on a push handle on which a clamping hook can be buckled with the moving trigger. The piston rod is provided with a rack engaged with a damping gear fixed in the gun body. The utility model ejects out water in the piston cylinder through the moving trigger pulling the piston rod. Under the reaction force of the springs, the piston when pulled causes the ejected water to be ejected farther. The damping gear on the gun body can effectively decelerate impulse of the pulled piston rod so as to prolong the service life of the utility model. The low-pressure toy water gun has the characteristics of simple structure, easy use, etc., and is suitable for various gun types.

Description

The low pressure water gun

Technical field:

The utility model relates to the water gun technical field, refers in particular to a kind of low pressure water gun, and it controls the emission of water by movable trigger, is fit to various rifle types.

Background technology:

Water gun mainly utilizes water to attack the adversary, does not have the injury power of common spring peashooter, and security is higher and interesting also higher, is fit to children and adult's amusement use.Existing water gun, include giant and low pressure hydraulic giant, the still low pressure hydraulic giant of wherein selling morely on the market, the low pressure hydraulic giant mainly is that piston cylinder is set in the body of a gun, utilization pushes away handle pulling piston and twitches in piston cylinder, will in the water sucker tube and with piston water be propelled away.This type toy hydraulic giant of picture, the rifle type that it generally can only make greatlyyer as tommy gun, then can not be installed as less rifle types such as pistols and to push away handle, so producer does not generally produce, just makes that also the water gun style on the market is more single.

Summary of the invention:

The purpose of this utility model is to provide a kind of main utilization activity trigger to control the emission of water at the deficiencies in the prior art and be applicable to the low pressure water gun of various rifle types.

For achieving the above object, the utility model adopts following technical scheme:

It comprises the body of a gun, forms handle on the body of a gun, and the handle position place is combined with a movable trigger,

Be fixed with water cup on the body of a gun, also be fixed with piston cylinder in the body of a gun, the outlet pipe that water cup is drawn is connected to piston cylinder, piston cylinder connects transmitting tube, be folded with spring between piston in the piston cylinder and the piston cylinder, the piston rod that piston connects is fixed on and pushes away on the handle, push away on the handle grab can with movable trigger snapping.

Form tooth bar on the described piston rod, this tooth bar and the damping gears engaged that is fixed in the body of a gun.

The utility model is by movable trigger pulling piston rod, water in the piston cylinder is launched, be subjected to the reaction force of spring during the piston pulling, make the water that emits spray fartherly, and the damping gear on the body of a gun can effectively slow down the piston impulse force in when pulling, thereby prolongs service life of the present utility model.The utlity model has characteristics such as simple in structure, easy to use, be fit to various rifle types.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model.

The specific embodiment:

See accompanying drawing 1, the utility model includes the body of a gun 10, form handle 12 on the body of a gun 10, handle 12 positions are combined with a movable trigger 14, be fixed with water cup 20 on the body of a gun 10, water cup 20 is used for storage of water, also is fixed with piston cylinder 30 in the body of a gun 10, the outlet pipe 22 that water cup 20 is drawn is connected to piston cylinder 30, and piston cylinder 30 connects transmitting tube 16.One check valve 40 is installed on the outlet pipe 22.

Be folded with spring 34 between piston 32 in the piston cylinder 30 and the piston cylinder 30, the piston rod 36 of piston 32 connections is fixed on and pushes away on the handle 38, push away on the handle 38 and form grab, this grab can with movable trigger 14 snappings.

Also be provided with in the body of a gun 10 for pushing away the chute that handle 38 moves.

During use, at first will push away handle 38 and pull back, and push away handle 38 pulling piston rods 36 and move backward, piston rod 36 spurs piston 32 again when mobile backward, compression spring 34 is buckled together up to the grab and the movable trigger 14 that push away on the handle 38, makes spring 34 generation deformation and has certain elastic potential energy; Pull movable trigger 14 again, it is released to push away handle 38, and piston rod 36 is pushed away forward, and spring 34 is released, and elastic potential energy converts kinetic energy to, promotes piston 32 and travels forward, thereby the water in the piston cylinder 30 is propelled away.

If spring 34 excessive compression then have bigger potential energy, when the emission water column, piston rod 36 will be vaporific with the water column that makes ejection before will promptly being pulled to, impact effect, but also may damage water gun.

In order to overcome above-mentioned ill effect, can on piston rod 36, form tooth bar, this tooth bar and damping gear 18 engagements that are fixed in the body of a gun 10 certainly, can add idler gear between damping gear 18 and the tooth bar.

When being filled with water in the piston cylinder 30, check valve 42 ends, and the water in water cup 20 can not pass through check valve 42, when launching one time, piston rod 36 spurs pistons 32 backward, and the pressure in the piston cylinder 30 reduce, check valve 42 is opened, and the water in water cup 20 flow in the piston cylinder 30 by outlet pipe 22.

The utility model is launched the water in the piston cylinder 30 by movable trigger 14 pulling piston rods 36, is subjected to the reaction force of spring 34 during piston 32 pullings, makes the water that emits spray fartherly.If replace pushing away handle 38 with pull bar, then the body of a gun 10 can make the shape of pistol.

The utlity model has characteristics such as simple in structure, easy to use, be fit to various long and short rifle types, have stronger interest.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
