[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, the present invention provides a technical solution: a single-handed sprinkler head, including: a main body mechanism 1, an auxiliary mechanism 2 is provided on the inner wall of the main body mechanism 1. The main body mechanism 1 includes a sprinkler head body 11. One end of the sprinkler head body 11 is provided with a connecting pipe 12. One end of the sprinkler head body 11 is fixedly communicated with one end of the connecting pipe 12. A fixed block 15 is provided on the outer side of one end of the connecting pipe 12. One end of the outer side of the connecting pipe 12 is fixedly connected with one end of the fixed block 15. A spring 1 16 is provided at the other end of the fixed block 15. The other end of the fixed block 15 is fixedly connected with one end of the spring 1 16. An arc-shaped plate 17 is provided at the other end of the spring 1 16. The other end of the spring 1 16 is fixedly connected with one side of the arc-shaped plate 17. An outer disc 13 is provided on the outer side of the connecting pipe 12. The outer side of the connecting pipe 12 is threadedly connected with the inner wall of the outer disc 13. A tapered column 14 is provided at the bottom of the outer disc 13. The bottom of the outer disc 13 is movably connected with the top end of the tapered column 14. The outer side of the tapered column 14 is in vertical sliding contact with the inner wall of the arc-shaped plate 17. One end of the arc-shaped plate 17 is in contact and fit with one end of the spacer block 111. A screw rod 110 is provided at one end of the spacer block 111. One end of the spacer block 111 is in contact with one end of the screw rod 110. A folding rod 19 is provided on the outer side of the screw rod 110. The outer side of the screw rod 110 is threadedly connected with the inner wall of the folding rod 19. One end of the folding rod 19 is fixedly connected with the outer side of the outer ring 18. The inner wall of the outer ring 18 is slidably connected with one side of the spacer block 111.

[0026] In this embodiment, when the modified single-handed nozzle is in use, in order to be compatible with rubber water pipes of different diameters, when connecting to a larger water pipe, the water pipe is first aligned with the arc-shaped plate 17. At this time, by rotating the outer disc 13, the tapered column 14 moves downward. During the downward movement, the tapered column 14 continuously exerts an external force on the arc-shaped plate 17, increasing the gap between the four arc-shaped plates 17 and contacting the inner wall of the water pipe until the water pipe is expanded and tightened. This mechanism allows the nozzle to adapt to rubber water pipes of different diameters without replacing any components, thereby improving the versatility and convenience of the product. And the user only needs to rotate the outer disc 13 without using additional tools or accessories, greatly simplifying the installation and disassembly process;

[0027] Secondly, after the arc-shaped plate 17 is expanded, due to the increased gap, water may seep out from the gap. Therefore, by rotating the screw rod 110, the cushion block 111 moves at its original position and enters the gap to fill the gap, which can effectively enhance the sealing performance, prevent water from seeping out from the gap, improve the use efficiency and reliability of the nozzle, and no matter how the diameter of the water pipe changes, only by adjusting the position of the cushion block 111 can ensure the seal, with a wide range of applications and enhanced versatility of the nozzle.

[0028] Embodiment 2

[0029] As Figures 3-4 shown, the auxiliary mechanism 2 includes a cross plate 21. One side of the cross plate 21 is provided with a second spring 22. One side of the cross plate 21 is fixedly connected to one end of the second spring 22. The other end of the second spring 22 is provided with a cushion block 111, and the other end of the second spring 22 is fixedly connected to the inner wall of the cushion block 111. One end of the cross plate 21 is provided with an outer ring 18, and one end of the cross plate 21 is fixedly connected to the inner wall of the outer ring 18.

[0030] In this embodiment, since the screw rod 110 and the cushion block 111 are not integrated, after use, in order for the cushion block 111 to automatically reset, a cross plate 21 is installed in the cushion block 111, and a second spring 22 is installed in the cross plate 21. The second spring 22 uses the cross plate 21 as a support point. After the external force disappears, it will release itself to reset the cushion block 111 without manual adjustment or intervention, which simplifies the operation steps, reduces the labor and time costs of the user, and the cross plate 21 can play a limiting role during the movement of the cushion block 111, allowing it to move along the designed path, which can prevent the cushion block 111 from deviating or exceeding the designed range and ensure that it stops or resets at the correct position.

[0031] Working principle:

[0032] As Figures 1-4As shown, by first aligning the water pipe with the arc-shaped plate 17, at this time, by rotating the outer disc 13, the tapered column 14 moves downward. During the downward movement, the tapered column 14 continuously exerts an external force on the arc-shaped plate 17, increasing the gap between the four arc-shaped plates 17 and simultaneously contacting the inner wall of the water pipe until the water pipe is expanded and tightened. This mechanism allows the nozzle to adapt to rubber waters of different diameters without replacing any components. Secondly, after the arc-shaped plate 17 is expanded, due to the increased gap, water may seep out from the gap. Therefore, by rotating the screw rod 110, the cushion block 111 moves from its original position and enters the gap to fill the gap, effectively enhancing the sealing performance and preventing water from seeping out from the gap;

[0033] Through the transverse plate 21 installed in the cushion block 111, and a second spring 22 is installed in the transverse plate 21. The second spring 22 uses the transverse plate 21 as a support point. After the external force disappears, it will release itself to reset the cushion block 111 without manual adjustment or intervention. This simplifies the operation steps, reduces the labor and time costs of the user, and the transverse plate 21 can play a limiting role during the movement of the cushion block 111, allowing it to move along the designed path, thus avoiding the cushion block 111 deviating from or exceeding the designed range.

[0034] The above are only the preferred embodiments of the present invention and do not limit 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 based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
