[0002] Patent No. CN219242964U discloses a socket-type valve mounting head. The utility model has a reasonable structural design. By connecting a butterfly valve to it through a docking structure, the butterfly valve can be used to control the opening and closing of the steel pipe end, thereby controlling the opening and closing of the pipeline end.

[0003] However, the above-mentioned existing socket-type valve mounting head is used to connect one end of the steel pipe to the inside of the pipeline that needs to be unblocked through the arrangement of a resistance ring, a docking structure and a butterfly valve. The friction force after the connection is increased by the resistance ring to prevent the steel pipe from sliding inside the pipeline. The butterfly valve is connected to it through the docking structure, and the opening and closing of the end of the steel pipe can be controlled by the butterfly valve. Since this device lacks a limiting structure for the steel pipe, the high pressure of the water flow during use can easily cause the steel pipe to loosen from the pipeline, resulting in water leakage.

[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] refer to Figure 1-5 The utility model provides a technical solution: it includes a valve mounting head body 1 and a water pipe 2, grooves 8 are opened on the symmetrical sides of the surface of the valve mounting head body 1, and a rotating shaft 10 is fixedly connected in the groove 8. The surface of the rotating shaft 10 is rotatably connected with a connecting plate 4, and the side of the connecting plate 4 is fixedly connected to a limiting block 9, and the surface of the water pipe 2 is fixedly connected with a fixing block 3. Limited grooves 5 are opened on the symmetrical sides of the surface of the fixing block 3. The side of the limiting block 9 is clamped in the limiting groove 5, and the front of the fixing block 3 is fixedly connected with a first spring 6. The inner ring of the first spring 6 is slidably sleeved on the surface of the water pipe 2, and one end of the first spring 6 is fixedly connected with a resist ring 7. By setting the resist ring 7, when the resist ring 7 is against the side of the valve mounting head body 1, the resist ring 7 will squeeze the first spring 6, and the elastic force of the first spring 6 itself can make the limiting block 9 more stable when it is stuck in the limiting groove 5.

[0022] The side of the water pipe 2 is slidably connected to the inner ring of the valve mounting head body 1 , and the diameter of the water pipe 2 matches the inner diameter of the valve mounting head body 1 .

[0023] The diameter of the annular ring 7 matches the diameter of the valve mounting head body 1 , and the inner diameter of the annular ring 7 matches the diameter of the water pipe 2 .

[0024] The front of the butt ring 7 abuts against the side surface of the valve mounting head body 1 , and the inner ring of the butt ring 7 is slidably sleeved on the surface of the water pipe 2 .

[0025] Among them, a second spring 11 is fixedly connected in the groove 8. By setting the second spring 11, the second spring 11 can clamp the limit block 9 in the limit groove 5 through the limit plate, and one end of the second spring 11 is fixedly connected to the side of the limit plate.

[0026] The number of the first springs 6 is set to two, and the number of the first springs 6 matches the number of the connecting plates 4 . The side surfaces of the connecting plates 4 are provided with anti-slip grooves.

[0027] The working principle of the present utility model is as follows: first, the staff puts the valve mounting head body 1 against the butt ring 7, and then, the staff presses the butt ring 7 backward through the valve mounting head body 1, and the butt ring 7 squeezes the first spring 6 to make it shrink. At the same time, the limit block 9 on the connecting plate 4 will be stuck in the limit groove 5. At this time, the valve mounting head body 1 can be stably installed on the water pipe 2. When the valve mounting head body 1 needs to be disassembled, the staff only needs to press one side of the connecting plate 4 to shrink the second spring 11. At the same time, the connecting plate 4 will drive the limit block 9 to separate from the limit groove 5, and the valve mounting head body 1 can be removed from the water pipe 2. The second spring 11 will push the connecting plate 4 to its original position for easy use next time.

[0028] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or changes based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
