Embodiment
Embodiment 1
According to Fig. 1 to Fig. 6, a kind of water gun structure described in the present embodiment, include what is be sealedly and fixedly connected Procapsid 1 and back casing 2.
The front end of the procapsid forms shower nozzle 15, and the procapsid is interior to form outlet pipe 14 positioned at shower nozzle rear； Front handlebar portion 11 is formed below the procapsid rear end, the forward upper in front handlebar portion forms the rod aperture 13 of circle, In the front handlebar portion front baffle 12 is formed below rod aperture.
The lower section of the back casing 2 forms rear-handle portion 21, and rear-handle portion rear end inwall corresponds to the position of rod aperture Piston cylinder portion 23 is formed, is formed above the front end of piston cylinder portion into water breach 231；Back casing rear end inwall correspondingly goes out The rearward end position of water pipe forms the water outlet pipe jointing part 25 for being connected and connecting with the outlet pipe；The back casing rear end into Type has the connectivity slot 24 for connecting the piston cylinder portion rear end and water outlet pipe jointing part rear end, and the back casing rear end is externally connected with envelope Close the connection groove lid 7 of the connectivity slot.
Rear bulkhead 22 is formed below piston cylinder portion in the rear-handle portion, the back casing upper end forms water filling Mouthfuls 26, a cock body 4 is connected with water filling port.
The rear bulkhead is tightly connected with front baffle；In the procapsid and back casing above front baffle and rear bulkhead Form water storage cavity.
Piston 5 is slidably fitted with the piston cylinder portion, the piston includes the piston head and circular tube shaped of integrally connected Piston bush 52；The piston head is slidably connected with piston cylinder portion inner wall sealing, the piston bush outer wall and rod aperture inwall Sealing is slidably connected.
Spring 6 is installed between the piston head and piston cylinder portion rear end in the piston cylinder portion.
Pressing lever 3 is connected with the piston bush, the pressing lever includes the press head 31 and inserted link 32 of integrally connected, The inserted link is inserted in the piston bush and is interference fitted with piston bush.
The inserted link close to the position of press head form annular neck 321, the piston bush leading section form with Neck coordinates the collar 521 of clamping.
Between the procapsid and back casing, and back casing is with connecting between groove lid by ultrasonic bonding, described Piston is installed to respective correspondence position with spring in procapsid, back casing and before connecting groove lid welding.
The procapsid, back casing and connection groove lid are formed along hydraulic giant fore-and-aft direction withdrawing pattern.So outlet pipe just may be used Directly with fore shell body by integral forming, compared to using independent flexible pipe connection piston cylinder portion and shower nozzle, present invention eliminates connection The process of outlet pipe and shower nozzle；Piston cylinder portion and outlet pipe are then connected by connectivity slot, and by connecting groove lid closed communication groove, Eliminate the process for being independently arranged piston cylinder portion and its being connected with outlet pipe.
The outlet pipe is welded as a whole simultaneously with water outlet pipe jointing part when procapsid, back casing weld.
Pressing lever piston when not by external force is pushed into offset with rod aperture rear end by spring so that water inlet indentation, there In open mode.
