Fig. 3 water gun structure cutaway view of the present utility model (opening lock-out state).

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail.

Anticipate as shown in the figure, this water pistol, it includes the body 1 of water pistol, and body adopts metal material to make, and becomes pistol shape substantially.Upper part of body has delivery port 13, water inlet 14 is arranged below, being provided with flowing water passage 15 in the body couples together water inlet 14 and delivery port 13, the outside of body is coated with plastic layer 110 and makes its whole one-tenth handgun shape, the water inlet 14 of body is shaped on and connects the interface of taking over as water pipe, it can be the structure of internal thread, it also can be externally threaded structure, or even other fast joint structure, the delivery port 13 of body is connected with nozzle 2, the opening and closing structure that makes the passage opening and closing is arranged in the flowing water passage 15, these are the same principles with traditional water pistol, here no longer carefully state, its special character is that above-mentioned opening and closing structure adopts in flowing water passage 15 as the bending part is provided with the piston seat 11 that cooperates with packed-piston 5, and have the opening 12 that is pressed into and ejects for packed-piston 5 accordingly, this is hole enlargement for the opening 12 that packed-piston 5 is pressed into and ejects in oral area place part, exactly its diameter is suitably enlarged a bit, hole enlargement place inner surface is opened internal thread, thereby fix a hold-doun nut 16 with being threaded, this hold-doun nut 16 has the through hole that cooperates and supply packed-piston 5 to pass with packed-piston 5, for good seal, here adopt special-shaped seal washer 17, sealing packing ring 17 1 side surfaces have bulge loop, simultaneously hold-doun nut 16 in the surface have with seal washer 17 on bulge loop carry out the annular groove of fitted seal, lining is gone up so special-shaped seal washer 17 between hold-doun nut 16 and the oral area hole enlargement, to prevent the leakage of water.Packed-piston 5 is the cylinders that adopt metal material to make, end in the flowing water passage is fixed with evagination pad 51, between pad and the end and the ring groove 52 of going into for seal washer 53 lining arranged, lining is gone into seal washer 53 then, so, when packed-piston 5 withstands piston seat 11, flowing water passage 15 can be blocked completely, cut off flowing water.Be equipped with back-moving spring 6 between evagination pad 51 and hold-doun nut 16 and the seal washer 17 thereof, its effect is when the locking of the spanner 3 disengaging activity collars 4 of water pistol, can automatically reset under back-moving spring 6 effects, packed-piston 5 is withstood piston seat 11, seal flowing water passage 15.The other end of packed-piston 5 passes the through hole of hold-doun nut 16 and the outside of dew place water pistol body 1, this end also has ring groove 54, fixedly one side at spanner 3 has the jack that inserts for packed-piston 5 outer ends accordingly, be generally circular hole, be connected with fixing seal piston 5 outer ends above the jack and carry out spacing connection elongated slot 31, packed-piston 5 is connected and fixed by the jack of spanner 3 and the top of spanner 3 at an end of water pistol outside, being connected and fixed of this movable formula, make spanner 3 be not easy to block malfunctioning, use flexibly.There is the support column 18 that withstands spanner 3 medial surfaces the position, body 1 middle and upper part of water pistol, for spanner can be rotated neatly around support column 18, be shaped on pivot pin 19 in the both sides of support column, medial surface at spanner 3 has the pivot pin seat that is mated accordingly, this pivot pin is local opening, and the pivot pin 19 on the support column 18 is embedded in the pivot pin seat easily.And the body bottom of water pistol has and is used for blocking the movable collar 4 that spanner 3 bottoms lock, preferably the spanner bottom also have be fixed in body on movable collar cooperate fixing grab 32, make grab 32 can lock movable collar 4 securely, thereby spanner is firmly fixed, be difficult for loose or dislocation.In order to improve the feel of water pistol, make on spanner 3 surfaces and point to hold and take a plurality of arcs that cooperate, its surface also is covered with plastic layer, the surface has by the part of perforate on the spanner plastic layer and spanner is fixed in the plastic layer, also the available metal rivet is further fixing with plastic layer and spanner, plastic layer and original metal spanner is fixing just very firm like this, even long-time use the, also difficult drop-off.Body 1 outside of water pistol is covered with plastic layer 110, and makes its shape and structure as rifle, is the plastic cement lamellar structure 111 of stratiform at the rear portion at handle position, and its high resilience can improve the fatigue of hand.The delivery port 13 of water pistol body has ring groove at oral area place inner surface, and the ring groove inner surface is shaped on the internal thread that is threaded with nozzle core 22, the nozzle core 22 that is threaded then, and lining seal washer 23 between nozzle core 22 ends and the groove.The root of nozzle core 22 has external screw thread, be connected and fixed the overcoat mouth 21 that is used for changing water spray water type with thread connecting mode, the front portion of nozzle core 22 have with overcoat mouth 21 inner surfaces on seal washer 28 carry out the spacing outer bulge loop 25 that cooperates, the root of screw thread also is an evagination over the nozzle core, circlewise, become like this with the lip-deep in the mouth seal washer 28 of overcoat and carry out spacing internal projecting ring, structure is very compact, nozzle core surface before the outer bulge loop 25 has uniform water jet 24 along circumference, the leading section of nozzle core has the lead 26 that cooperates with overcoat mouth water jet 24 simultaneously, open loop connected in star on the lead 26, like this by the rotary sleeve mouth, just regulated the water outlet interval area size between nozzle core 22 and the overcoat mouth 21, thereby can play the effect of regulating water spray water type, overcoat mouth outer surface is with plastic tube 27 to improve feel.
