DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model. Embodiment 1
[0022] Please refer to Figures 1-4 The embodiment provides a valve for a buried telescopic spray rod, which comprises a tubular shell 1, the tubular shell 1 can be connected with a telescopic pipe and a spray head at both ends, a valve core is rotationally arranged in the tubular shell 1, the valve core preferably adopts a ball valve core 4, the ball valve core 4 can realize the adjustment of the fluid flow in the tubular shell 1 by rotation, in order to realize the adjustment of the ball valve core 4 and at the same time make the valve not affect the telescopic movement of the telescopic pipe in the land, a recessed mouth 10 is formed in the surface of the tubular shell 1, a valve core adjusting knob 11 connected with the ball valve core 4 is rotationally arranged in the recessed mouth 10, and a valve core driving part is arranged on the valve core adjusting knob 11 and used for driving the valve core adjusting knob 11 to rotate.
[0023] Specifically, referring to Figures 1-3 The tubular shell 1 comprises a first connecting pipe 2 and a second connecting pipe 3, a valve core mounting cavity 5 is arranged on one side of the first connecting pipe 2, the ball valve core 4 is arranged in the valve core mounting cavity 5, and one side of the second connecting pipe 3 is located in the valve core mounting cavity 5 and is threadedly connected with the valve core mounting cavity 5. As a conventional design familiar to those skilled in the valve field, sealing rings should also be arranged on both sides of the ball valve core 4 to ensure that the ball valve core 4 has good sealing performance. Specifically, sealing rings 7 located on both sides of the ball valve core 4 are fixedly arranged in the valve core mounting cavity 5, and the ball valve core 4 is in close contact with the sealing rings 7. In the application, sealing ring clamping grooves 6 located on both sides of the ball valve core 4 are formed on the inner wall of the valve core mounting cavity 5 and the side wall of the second connecting pipe 3, and the sealing rings 7 are fixedly arranged in the sealing ring clamping grooves 6. The design of the sealing rings 7 is a conventional operation familiar to those skilled in the art, and will not be described herein. At the same time, in order to realize the connection with the telescopic pipe and the spray head, external threads 15 and internal threads 8 are arranged on the sides of the first connecting pipe 2 and the second connecting pipe 3 away from each other.
[0024] Furthermore, in order to connect the valve adjusting knob 11 to the ball valve core 4, refer to... Figures 1-3 As shown, the groove 10 is provided on the first connecting pipe 2, and the groove 10 communicates with the valve core mounting cavity 5. A limiting groove 9 is formed on the top of the ball valve core 4, and a limiting block 13 is provided at the lower end of the valve core adjusting knob 11. The limiting block 13 is inserted into the limiting groove 9. Preferably, the limiting block 13 is a rectangular block, and the limiting groove 9 is a rectangular groove. It can also be designed as other conventional polygonal shapes familiar to those skilled in the art, without further elaboration. Meanwhile, as... Figure 3 , Figure 4 As shown, preferably, the valve core drive part is an adjustment socket 12 opened on the top of the valve core adjustment knob 11. The shape of the adjustment socket 12 is preferably polygonal, which is a conventional design familiar to those skilled in the art, so that the polygonal wrench can be inserted into the adjustment socket 12 and the adjustment socket 12 can be rotated. Its shape itself will not be further described or limited.
[0025] At the same time, in order to prevent the valve core adjusting knob 11 from easily falling out of the groove 10, such as Figures 1-3 As shown, a protruding retaining ring 14 is provided on the outside of the valve core adjusting knob 11. The diameter of the retaining ring 14 is larger than the inner diameter of the groove opening 10, and the retaining ring 14 is located at the lower end of the groove opening 10. As is common knowledge familiar to those skilled in the art, the retaining ring 14 only contacts the groove opening 10, and the two are movably connected, so that the lower end of the groove opening 10 is limited by the retaining ring 14 to prevent the valve core adjusting knob 11 from easily dislodging from the groove opening 10.
[0026] In practical applications, during valve assembly, the two sealing rings 7 are first pressed against or adhered to the sealing ring grooves 6 on the valve core mounting cavity 5 and the second connecting pipe 3. Then, the ball valve core 4 is placed into the valve core mounting cavity 5, aligning the limiting groove 9 at the top of the ball valve core 4 with the recessed opening 10. The second connecting pipe 3 is then screwed into the valve core mounting cavity 5, pressing the sealing rings 7 against the ball valve core 4 to connect the first connecting pipe 2 and the second connecting pipe 3. Subsequently, the valve core adjusting knob 11 is pressed into the recessed opening 10, pressing the retaining ring 14 to the lower end of the recessed opening 10, so that the limiting block 13 is precisely engaged in the limiting groove 9. It should be noted that the valve core adjusting knob 11 should be made of a deformable material, such as plastic or other conventional materials familiar to those skilled in the art, so that it can deform when pressed into the recessed opening 10, allowing the retaining ring 14 to be pressed to the lower end of the recessed opening 10. The material selected for the valve in this application should be a conventional choice familiar to those skilled in the art, and will not be further specified.
[0027] In practical application, the valve is assembled to the telescopic spray rod by connecting the outer thread 15 on the first connecting pipe 2 with the telescopic pipe of the telescopic spray rod, and then connecting the spray head with the second connecting pipe 3 through the inner thread 8. When the water flow of the spray head is needed, the corresponding polygonal handle is inserted into the adjusting socket 12, and the water flow is adjusted by rotating the handle to adjust the valve core knob 11. When the spray head needs to be replaced, the valve is closed in advance, the total valve is opened, the telescopic spray rod is extended to the ground under the water pressure, and then the spray head is replaced.
[0028] It should be noted that the above embodiments are only for specific and clear description of the technical solutions and technical features of the present application. For those skilled in the art, the solutions or features that belong to the prior art or common knowledge are not described in detail in the above embodiments.
[0029] In addition, the technical solutions of the present application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
