[0029] Referring to FIG. 1-FIG. 7, an embodiment provides a hand-cranked water gun with a hand-cranked driving device, including a gun 100, where a water tank 200 and a shooting component 300 of the hand-cranked driving device are fixedly mounted in the gun 100, and a hand crank 400 of the hand-cranked driving device is detachably connected to the gun 100 to rotatably drive the shooting component 300 to perform a shooting action.

[0030] In this embodiment, the gun 100 includes a gun body 110 and a gun barrel 120 rotatably connected to the gun body 110. Openings 111 are respectively formed in both sides of the gun body 110, and opening ends of the first groove body and the second groove body in the shooting component 300 are respectively formed on the two openings 111, through which the hand crank 400 can be inserted into one of the openings 111 and fixed in the first groove or the second groove of the shooting component 300, so as to drive other components of the shooting component 300 to match to perform the shooting action. It may be understood that a hand grip 130 and a handle 140 convenient for a player to fix the gun body 110 are arranged on the gun body 110, and the hand grip 130 and the handle 140 may further be used to increase the simulation degree of the gun 100. In other implementations of the present disclosure, the gun barrel 120 may be fixed to the gun body 110, and the gun body 110 may not be provided with the handle 140.

[0031] The gun barrel 120 is of a penetrating structure. An elastic buckling plate 121 is arranged on an outer wall of one end of the gun barrel 120. The elastic buckling plate 121 may be buckled in the inner shell of the shooting component 300, so that when the inner shell is controlled to rotate, the gun barrel 120 can rotate with the gun body 110 to simulate a rotary shooting action of a Gatling gun, so that the interestingness is improved.

[0032] In this embodiment, the water tank 200 is a built-in water tank. A water inlet 210 and a water outlet 220 are formed in the water tank 200. The water inlet 210 is exposed out of the gun body 110, so that the player adds water into the water tank 200 conveniently. The water outlet 220 is communicated to the cylinder block of the shooting component 300 through a pipeline, and in the process that the piston rod of the shooting component 300 reciprocates, a water flow in the water tank 200 may flow to the cylinder block via the water outlet 220 under the action of a water pressure. In other implementations of the present disclosure, the water tank 200 may also be an external water tank such as a backpack water tank.

[0033] In this embodiment, the shooting component 300 includes a shell 310, an inner shell 320 rotatably connected in the shell 310, a cylinder block 330 fixed in the shell 310, connecting shafts 340 rotatably penetrating through both sides of the shell 310, and a first groove body 350 and a second groove body 360 respectively fixed to both ends of each of the connecting shafts 340, a piston rod 370 movably connected in the shell 310 in a reciprocating manner, and a driving wheel 380 in driving connection to the piston rod 370 through a driving component 390. In other implementations of the present disclosure, the shooting component 300 may not be provided with the inner shell 320, and in this case, the gun barrel 120 is not provided with the elastic buckling plate 121 and is fixed to the gun body 110.

[0034] The inner shell 320 is of a penetrating structure, an outer gear ring 321 is arranged on the inner shell 320, and the outer gear ring 321 meshes with the driving component 390 to be driven by the driving component to rotate. Buckling openings 322 are formed in a side wall of the inner shell 320. The number of the buckling openings 322 is the same as the number of the elastic buckling plates 121. One elastic buckling plate 121 may be fixed in each buckling opening 322 in a buckled manner, so that the gun barrel 120 can be fixed in the inner shell 320 and rotate with the inner shell 320.

[0035] The piston rod 370 is movably connected in the cylinder block 330. A water intake 331 and a jetting orifice 332 are adjacently formed at the same end of the cylinder block 330. The water intake 331 is communicated to the water outlet 220 through a pipeline, the jetting orifice 332 stretches into the inner shell 320, and one-way valves 333 are movably connected in the water intake 331 and the jetting orifice 332, respectively. When the piston rod 370 is controlled in the cylinder block 330 to reciprocate, the one-way valves 333 in the water intake 331 and the jetting orifice 332 can be opened and closed correspondingly under control of the air pressure, respectively, to eject a water flow from the jetting orifice 332 after the cylinder block 330 sucks water inward. The working principle of the one-way valve 333 has been disclosed in the prior art, which is not described in detail herein.

[0036] In this embodiment, the connecting shaft 340 is a quadrangular shaft body to increase the fastening connection of the first groove body 350 and the second groove body 360 in a circumferential rotating direction to prevent slip fit between the connecting shaft 340 and the first groove body 350 or the second groove body 360, so that a rotating purpose cannot be achieved. In other implementations of the presented disclosure, the connecting shaft 340 may be another polygon prism or cylinder.

[0037] In this embodiment, the first groove body 350 is in slip fit in the driving wheel 380, and moreover, the first clamping portion 351 is arranged on the first groove 350. The first clamping portion 351 is clamped with the driving wheel 380 to drive the driving wheel 380 to rotate in the same direction through the first clamping portion 351 when the first groove body 350 rotates. In other implementations of the presented disclosure, according to different structures of the used driving component 390, the first groove body 350 may also be adjusted to be slidably connected and fixedly connected to the driving wheel 380.

[0038] It may be understood that hand cranks 400 are detachably connected in the first groove body 350 and the second groove body 360. In this embodiment, buckling openings 352 are formed in side walls of the first groove body 350 and the second groove body 360. The buckling openings 352 are connected to the hand cranks 400 in a buckled manner, so that they are detachably connected. Guide edges 353 are further arranged on the side walls of the first groove body 350 and the second groove body 360. The guide edges 353 and the hand cranks 400 are in slip fit to play roles of guiding the insertion and further enhancing the connection. In other implementations of the present disclosure, the buckling openings 352 and / or guide edges 353 may not be arranged on the side walls of the first groove body 350 and the second groove body 360. In this case, the first groove body and the second groove body may be detachably connected to the hand cranks 400 by other structures such as threaded structures and insertion structures.

[0039] In this embodiment, a rack 371 is arranged on the piston rod 370, one end of the piston rod 370 is hermetically and movably arranged in the cylinder block 330 through a sealing element 372, and the other end of the piston rod 370 is connected in the shell 310 through an elastic member 500. The rack 371 may be driven by the driving component 390 to drive the end provided with the sealing element 372 to move in the cylinder block 330, and in this case, a negative pressure is formed in the cylinder block 330 to suck water, and the elastic member 500 is in a compressed state. When the rack 371 is separated from the driving component 390, the piston rod 370 moves fast toward the cylinder block 330 under an elastic force to compress the water flow in the cylinder block 330, so that the water flow is ejected out of the jetting orifice 332. In other implementations of the presented disclosure, according to different structures of the used driving component 390, the piston rod 370 may not be provided with the rack 371.

[0040] A second clamping portion 381 clamped with the first clamping portion 351 is arranged on the driving wheel 380. In this embodiment, the first clamping portion 351 is a pulling claw elastically stretching outward from the first groove body 350, the second clamping portion 381 is an inner gear ring, and the pulling claw is unidirectionally clamped with the inner gear ring. When the first groove body 350 rotates toward one direction, the pulling claw is clamped with the inner gear ring to drive the driving wheel 380 to rotate, and if the first groove body 350 rotates toward another reverse direction, the pulling claw may rotate in the inner gear ring, i.e., the pulling claw cannot drive the driving wheel 380 to rotate. It should be noted that the pulling claw and the inner gear ring are configured to match with the driving component 390, so that the driving wheel 380 may only drive the piston rod 370 to move toward a direction where the cylinder block 330 is pulled through the driving component 390. According to different structures of the used driving component 390, the first clamping portion 351 and the second clamping portion 381 may also be adjusted to other clamping structures such as elastically movable pulling rods and edge bumps.

[0041] In this embodiment, the driving component 390 includes a missing teeth gear 391 in meshing connection to the rack 371 and a transmission group 392 in transmission connection between the missing teeth gear 391 and the driving wheel 380. The transmission group 392 includes a first gear 3921 meshing with the driving wheel 380, a second gear 3922 coaxially fixed with the missing teeth gear 391, and a third gear 3923 meshing with the outer gear ring 321. The second gear 3922 meshes with the first gear 3921, and the third gear 3923 is coaxially connected to the first gear 3921 through a non-return member. When the driving wheel 380 rotates, the missing teeth gear 391 may be controlled by the first gear 3921 and the second gear 3922 in sequence to rotate to drive the piston rod 370 to move, so as to achieve water sucking and water jetting. The outer gear ring 321 may also be controlled by the first gear 3921 and the third gear 3923 to rotate to drive the inner shell 320 to rotate, so as to drive the gun barrel 120 to rotate. In other implementations of the present disclosure, the driving component 390 may also be a conveyor belt, a connecting structure, another wheel chain structure, and the like.

[0042] It may be understood that the non-return member is configured to prevent the missing teeth gear 391 from being driven to rotate through the transmission group 392 when the gun barrel 120 is rotated by an external force. The non-return member includes a gear body 3924 fixed to the first gear 3921, an elastic movable strip 3925 stretching outward is arranged on an outer wall of the gear body 3924, and a clamping block 3926 detachably clamped with the inner ring 3927 of the third gear 3923 is arranged on the elastic movable strip 3925. The elastic movable strip 3925 can drive the inner ring 3927 to rotate when the first gear 3921 rotates. If the third gear 3923 rotates under the action of an external force, the elastic movable strip 3925 bounces under stress, so that the inner ring 3927 rotates on the clamping block 3926, so that the first gear 3921 cannot be reversely driven to rotate.

[0043] Each of the hand cranks 400 includes a connecting rod 410, a holding rod 420, and a main body rod 430, where both ends of the body rod 430 are fixedly connected to the connecting rod 410 and the holding rod 420, respectively, the connecting rod 410 is detachably fixed in the first groove body 350 or the second groove body 360, and the holding rod 420 is configured for the player to hold the hand crank to rotate the hand crank 400.

[0044] In this embodiment, a buckling block 411 is movably arranged on the connecting rod 410, and the buckling block 411 is in buckling connection in the buckling opening 352. Specifically, the buckling block 411 is rotatably connected to an outer wall of the connecting rod 410 through a spring, a pressing block 412 is movably arranged on the connecting rod 410, when the pressing block 412 moves, the pressing block may push the buckling block 411 to rotate into the connecting rod 410, and the spring is configured to drive the buckling block 411 to rotate out of the connecting rod 410. Therefore, the connecting rod 410 is inserted into the first groove body 350 or the second groove body 360 to be buckled and fixed in the first groove body 350 or the second groove body 360 through the buckling block 411, so that the connecting operation is simple and convenient. If it is necessary to detach the hand crank 400 from the first groove body 350 or the second groove body 360, the pressing block 412 is pressed to push the buckling block 411 to rotate into the connecting rod 410 to fast pull the hand crank 400 away, so as to achieve reversing connection or detached storage.

[0045] For clarity, some features described in independent embodiments of the present disclosure may be combined in a single embodiment for use. Moreover, various features of the present disclosure described in the single embodiment may also be used independently or in combination in any appropriate form.
