[0002] A water gun nozzle refers to a device specifically designed to spray water in different forms and pressures. Water gun nozzles are widely used in fields such as household cleaning, gardening irrigation, industrial cleaning, and fire extinguishing. It is usually connected to a water pipe, and different spraying modes and water flow intensities can be achieved by adjusting the nozzle to meet various specific requirements.

[0003] In the existing technology, traditional nozzles require manual switches to control the water flow, which is complex to operate and prone to misoperation, affecting the use effect. Secondly, the manual switch design increases the wear rate of the nozzle and reduces the service life. In addition, when users need to frequently open and close the water flow during operation, manual operation is particularly inconvenient, increasing the complexity of use. Since the liquid passage cannot be automatically adjusted to achieve automatic control of the water flow, the operation convenience is reduced. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art and provide a water gun nozzle with a self-locking structure.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A water gun nozzle with a self-locking structure, comprising: a self-locking mechanism, a guiding mechanism is arranged outside the self-locking mechanism, the self-locking mechanism includes a hollow cavity, a side rod is arranged on the inner wall of the hollow cavity, one end of the side rod is fixedly connected to the inner wall of the hollow cavity, a spring is arranged in the middle of the side rod, the middle of the side rod is fixedly connected to the bottom end of the spring, the top end of the spring is fixedly connected to the bottom side of a closing plate, the outer side of the closing plate fits with the edge of the inner wall of the hollow cavity, a vertical rod is arranged on the top side of the closing plate, and the bottom end of the vertical rod is fixedly connected to the top side of the closing plate.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 - 4 shown, the present utility model provides a technical solution: a water gun nozzle with a self-locking structure, including: a self-locking mechanism 1, a guiding mechanism 2 is arranged outside the self-locking mechanism 1, the self-locking mechanism 1 includes a hollow cavity 19, a side rod 16 is arranged on the inner wall of the hollow cavity 19, one end of the inner wall of the hollow cavity 19 is fixedly connected to one end of the side rod 16, a spring 18 is arranged in the middle of the side rod 16, the middle of the side rod 16 is fixedly connected to the bottom end of the spring 18, the top end of the spring 18 is fixedly connected to the bottom side of the closing plate 14, the outside of the closing plate 14 fits with the edge of the inner wall end of the hollow cavity 19, a vertical rod 13 is arranged on the top side of the closing plate 14, the top side of the closing plate 14 is fixedly connected to the bottom end of the vertical rod 13, a pressing rod 12 is arranged at the top end of the vertical rod 13, the top end of the vertical rod 13 is vertically corresponding to the bottom end of the pressing rod 12, a water gun body 11 is arranged at the top end of the pressing rod 12, the top end of the pressing rod 12 is fixedly connected to one end of the water gun body 11, one end of the water gun body 11 is threadedly connected to one end of the hollow cavity 19, a movable arm 111 is arranged outside the hollow cavity 19, the middle of the outside of the hollow cavity 19 is movably connected to the middle of the movable arm 111, a clamping ring 112 is arranged at the bottom end of the hollow cavity 19, the bottom end of the hollow cavity 19 is fixedly connected to one side of the clamping ring 112, one side of the top end of the movable arm 111 is vertically slidably connected to the outside of the outer ring 110, a guide rail 17 is arranged inside the side rod 16, a folding rod 15 is arranged on the inner wall of the guide rail 17, one end of the inner wall of the guide rail 17 is vertically slidably connected to one end of the folding rod 15, and the other end of the folding rod 15 is fixedly connected to the bottom side of the closing plate 14.

[0026] In this embodiment, when the water gun nozzle with a self-locking structure is in use, the water pipe is sleeved on one end of the hollow cavity 19. Then, the outer ring 110 is moved downward. During the downward movement, the outer ring 110 exerts pressure on the top end of the movable arm 111. Furthermore, since a clamping ring 112 is designed at the bottom end of the movable arm 111, the clamping ring 112 will contact the water pipe after the movable arm 111 is pressured, and the water pipe and the hollow cavity 19 are tightly connected. The user only needs to simply move the outer ring 110 downward to complete the connection between the water pipe and the hollow cavity 19, without complex operation steps or additional tools;

[0027] Secondly, the water gun body 11 is threadedly connected to the top end of the hollow cavity 19. During the connection process, the pressure rod 12 squeezes the vertical rod 13, forcing the vertical rod 13 to move downward. Since the vertical rod 13 moves downward, the closing plate 14 naturally no longer fits with the edge of the inner wall of the hollow cavity 19. Thus, the liquid passage is opened. On the contrary, when the water gun body 11 is disconnected from the hollow cavity 19, the spring 18 will reset the closing plate 14 to make it fit with the edge again, closing the liquid passage. This automatic opening and closing mechanism ensures that the liquid passage is automatically adjusted according to the connection state.

[0028] Embodiment 2

[0029] As Figures 1 - 4 shown, the guiding mechanism 2 includes a back plate 21. A guide block 22 is arranged on the inner wall of the back plate 21, and one end of the guide block 22 is fixedly connected to the inner wall of the back plate 21. The other end of the guide block 22 is provided with an outer ring 110, and the other end of the guide block 22 is fixedly connected to the inner side of the outer ring 110. One side of the back plate 21 is fixedly connected to the outer side of the hollow cavity 19.

[0030] In this embodiment, in order to make the downward movement of the outer ring 110 smoother, a back plate 21 is installed on one side of the hollow cavity 19. In this way, when the outer ring 110 moves downward, the guide block 22 on the outer ring 110 will move within the back plate 21, providing accurate positioning and movement trajectory for the outer ring 110. And this form also prevents the outer ring 110 from being lost due to other factors, which increases the stability and reliability of the system and avoids the situation of accidental detachment or loss of the outer ring 110.

[0031] Working principle:

[0032] As Figures 1 - 4As shown, the water pipe is sleeved with one end of the hollow cavity 19, and then the outer ring 110 is moved downward. During the downward movement, the outer ring 110 will exert pressure on the top end of the movable arm 111. Furthermore, since the clamping ring 112 is designed at the bottom end of the movable arm 111, when the movable arm 111 is under pressure, the clamping ring 112 will contact the water pipe, and the water pipe will be tightly connected to the hollow cavity 19. Secondly, by threadedly connecting the water gun body 11 to the top end of the hollow cavity 19, during the connection process, the pressure rod 12 will squeeze the vertical rod 13, forcing the vertical rod 13 to move downward. Since the vertical rod 13 moves downward, the closing plate 14 will naturally no longer fit with the edge of the inner wall of the hollow cavity 19, and thus the liquid passage is opened. On the contrary, when the water gun body 11 is disconnected from the hollow cavity 19, the spring 18 will reset the closing plate 14 to make it fit with the edge again and close the liquid passage;

[0033] A back plate 21 is installed on one side of the hollow cavity 19. In this way, when the outer ring 110 moves downward, the guide block 22 on the outer ring 110 will move within the back plate 21, providing accurate positioning and a movement trajectory for the outer ring 110. And this form also prevents the outer ring 110 from being lost due to other factors, which increases the stability and reliability of the system.

[0034] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
