The flow-adjustable rear handle water gun, as shown in Figures 1 to 3, is a flushing product that is convenient for garden watering and cleaning. Its structure is mainly composed of the gun body 2, the water outlet component 3, the pull rod 5, the pull rod spring 7, Handle 10 and adjusting wrench 9 etc. constitute.

The gun body 2 is mainly used as a holding part and an important water passage part of the water gun, so the gun body 2 is provided with a flexible sleeve, and the outer surface of the flexible sleeve is provided with a plurality of curved surface designs that can be conveniently held by the palm of the human body. In the gun body 2, there is a water inlet channel 21 with a cross section of "7" shape. The "7" font water inlet channel is composed of a horizontal channel and a vertical channel. The head is made as water outlet, and vertical channel is positioned at the bottom of gun body 2 and is made water inlet, and a water inlet joint 1 that is installed in water inlet is set, can be used for connecting water inlet hose externally and provide water source for gun body.

The water outlet assembly 3 is arranged on the head of the gun body 2, and it is composed of a water outlet seat 31, a water outlet sleeve 32 installed in the water outlet seat, and a water outlet panel 33 connected to the head of the water outlet seat by screws; wherein, the water outlet seat 31 The rear part is provided with a connecting pipe 312, which is sealed and fixed in the water outlet through the connecting pipe. The connecting pipe 312 is provided with a water inlet hole 311, and the water inlet hole is connected with the water inlet channel 21; and the water outlet jacket 32 It can cooperate with the water outlet panel 33 to adjust various spraying shapes of the water splash.

The gun body 2, that is, the horizontal passage, is provided with a horizontally movable pull rod 5, which can rotate and axially reciprocate in the horizontal passage; the front end of the pull rod 5 is provided with a circle of radially surrounding The embedded groove 54 is provided with a fixed sealing ring 4 embedded in the groove, and the outer circumference of the sealing ring is moved axially by the tension rod 5 to form a sealing contact with or disengage from the water inlet hole 311 in the water outlet seat 31, thereby realizing The water outlet of the whole water gun is opened and closed; the rear side of the embedded groove 54 is provided with four ribs 51 uniformly distributed on the circumference, and each rib is extended along the axial direction of the pull rod 5 .

Simultaneously, the pull rod 5 is also covered with a pull rod spring 7 and a regulating valve 6, which is provided with a valve cavity 61 with a front end opening and a closed rear end as shown in Figure 6, and the valve cavity communicates with the water inlet hole 311. The pull rod 5 penetrates into the valve cavity 61, and the pull rod spring 7 is also just hidden in the valve cavity 61, and the front end of the pull rod spring is pushed and installed on the four ribs 51, and the rear end is pushed and installed on the bottom of the valve cavity 61. On the wall, the push of the pull rod spring 7 makes the pull rod 5 always have the driving force to move axially forward.

The side wall of the front end of the valve cavity 61 is provided with a water inlet gap 63, which can communicate the valve cavity 61 and the water inlet channel 21 respectively, and three track grooves 62 are also provided on the inner wall of the valve cavity 61, The three track grooves form a position correspondence with the three ribs 51 at the front end of the tie rod 5 and are fitted with axial movement, that is, the regulating valve 6 can be rotated synchronously by the rotation of the tie rod 5, but it will not hinder the movement of the tie rod 5 in the regulating valve. Axial movement within 6. When the pull rod 5 drives the regulating valve 6 to rotate at the same time, the water flow rate of the water inlet gap 63 on the regulating valve 6 will be changed in size, and the flow regulation of the water outlet of the water gun will be realized.

The rear end of the pull rod 5 protrudes from the gun body 2 and is exposed, and a seal ring 11 is arranged between the pull rod 5 and the gun body 2. The seal ring is installed at the rear of the regulating valve 6, and its function is to prevent the pull rod 5 from rotating or moving. Occurs the water source leakage in the gun body 2 during.

The rear handle 10 is hingedly installed at the rear of the gun body, and a circular hole 101 is provided at the upper end of the rear handle for the rear end of the pull rod 5 to move through. When the rear end of the pull rod 5 passes through the gun body 2 and the circular hole 101 in sequence Finally, the button 52 set at the rear end of the pull rod 5 and the undercut 93 set on the adjustment wrench 9 form a fastened and fixed connection relationship. The size of the connection wrench 9 is greater than the inner diameter of the round hole 101, so after pressing The handle 10 will push the adjustment wrench 9 to drive the pull rod 5 to move axially backward, the sealing ring 4 at the front end of the pull rod can leave the water inlet hole 311, and the water spray of the whole water gun will be opened; , will drive the pull rod 5 to move axially forward under the action of the pull rod spring 7, so that the seal ring 4 re-seals and contacts the water inlet 311, and the water spray of the whole water gun is just closed.

The rear end of the pull rod 5 and the adjustment wrench 9 are respectively set as a transmission assembly structure of a flat shaft 53 and a flat hole 92. Through this design structure, the pull rod 5 can be driven to rotate synchronously when the adjustment wrench 9 rotates. , and then make the regulating valve 6 also form a rotation, so it plays the role of regulating the water flow, and in order to facilitate the rotation of the adjustment wrench 9, a paddle 91 with anti-skid pattern as shown in Figure 7 can also be designed on it, so that the operation is more convenient. save effort.

The rear portion of the gun body 2 is provided with a buckle 8, and the bottom of the buckle is provided with a pair of extension feet extending downward and hinged on the gun body 2, and the top of the buckle can be turned by the buckle 8 to fall backward or to The front is upright; its design purpose is that when the rear handle 10 is pressed to make the water gun in the state of water discharge, the top of the buckle 8 is tilted backwards and withstands the upper end of the rear handle 10, so that the palm does not need to be pressed all the time to operate the rear handle 10. Realize the continuous water spraying of the water gun; otherwise, the above-mentioned function can be released by erecting the top of the buckle 8 forward, which is usually suitable for the intermittent water spraying of the water gun.

The utility model can drive the reciprocating movement of the pull rod 5 by pressing the rear handle 10 combined with the elastic push of the pull rod spring 7, and then realize the normal water spray opening and closing of the water gun; and the synchronous rotation of the regulating valve 6 is driven by rotating the pull rod 5, and Make the water inlet gap 63 on the regulating valve change in the size of the water flow, and then realize the flow adjustment of the water outlet of the water gun. This water gun with both opening and closing of water spray and flow adjustment is undoubtedly more convenient to use.
