[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-Figure 4 As shown, a water supply pipe valve with a locking structure includes a valve seat 1, a connecting seat 2 is fixedly installed on the upper part of the valve seat 1, and a fixed seat 3 is fixedly installed on the upper part of the connecting seat 2, a valve stem 4 is rotatably connected inside the fixed seat 3, the valve stem 4 penetrates into the interior of the valve seat 1 and is fixedly connected to a valve ball, a locking structure 5 is provided between the valve stem 4 and the fixed seat 3, the locking structure 5 includes a fixed toothed disc 6 and a movable toothed disc 7, the fixed toothed disc 6 is fixedly installed at the external top position of the fixed seat 3, the movable toothed disc 7 is sleeved on the outside of the valve stem 4, and the fixed toothed disc 6 is meshed and matched with the movable toothed disc 7.

[0025] In this embodiment, the outer surface of the valve stem 4 is provided with a plurality of grooves, and the contact surface between the movable toothed disc 7 and the valve stem 4 is provided with a plurality of convex strips;

[0026] The groove and the convex strip can prevent the movable toothed disc 7 from rotating outside the valve stem 4, thereby ensuring that the movable toothed disc 7 can only move vertically.

[0027] In this embodiment, a rotating handle 8 is fixedly mounted on the outside of the movable toothed disc 7;

[0028] The rotating handle 8 can conveniently operate the movable toothed disc 7 to rotate, thereby driving the valve stem 4 to rotate.

[0029] In this embodiment, a clamping structure is provided between the upper portion of the movable toothed disc 7 and the valve stem 4, and the clamping structure includes a rotating rod 9, which is rotatably connected to the top end of the valve stem 4, and a baffle 10 is installed on the upper portion of the rotating rod 9 through a nut 11, and a spring 12 is sleeved on the outer portion of the rotating rod 9 between the baffle 10 and the movable toothed disc 7;

[0030] The clamping structure can ensure the stability of the movable toothed disc 7 and the fixed toothed disc 6 after they are meshed.

[0031] In this embodiment, a stud is provided at the top of the rotating rod 9, the diameter of the stud is smaller than the diameter of the rotating rod 9, and the contact surface between the baffle 10 and the stud is larger than the diameter of the stud and smaller than the diameter of the rotating rod 9, and the nut 11 is threadedly connected to the stud;

[0032] The provision of the nut 11 can facilitate the removal of the baffle 10 , thereby facilitating the removal of the spring 12 .

[0033] In this embodiment, the rotating handle 8 is composed of a circular ring and a plurality of connecting rods. The plurality of connecting rods are fixedly connected to the outside of the movable gear plate 7 in a circular array, and the circular ring is fixedly installed on the outside of the plurality of connecting rods.

[0034] It should be noted that the utility model is a water supply pipeline valve with a locking structure. When in use, the inlet and outlet pipes at both ends of the valve seat 1 are connected to the external pipeline respectively. The medium of the external pipeline enters through the inlet pipe and is discharged from the outlet pipe through the valve ball. During use, the rotating handle 8 is lifted by hand, and the rotating handle 8 drives the movable toothed disc 7 to move upward, so that the movable toothed disc 7 is separated from the fixed toothed disc 6. Then the rotating handle 8 is rotated, and the rotating handle 8 drives the valve stem 4 to rotate through the fixed toothed disc 6 to adjust the opening and closing of the valve or the flow rate control. After adjustment, the rotating handle 8 is released, and the elastic force of the spring 12 pushes the movable toothed disc 7 downward, so that the movable toothed disc 7 is meshed with the fixed toothed disc 6. Since the fixed toothed disc 6 is fixed, when the movable toothed disc 7 is meshed with it, the fixed toothed disc 6 can limit the movable toothed disc 7 from rotating, thereby ensuring that the valve stem 4 will not rotate.

[0035] By setting up a locking structure, the position of the valve stem can be locked without human operation to ensure that the valve stem will not rotate, thereby ensuring that the valve as a whole will not leak or have inaccurate flow control problems;

[0036] By setting up a clamping structure, the stability of the engagement between the movable toothed disc and the fixed toothed disc in the locking structure can be ensured, and the rotating rod and the valve stem are connected in a rotating manner. Therefore, in the event of accidental collision, the valve stem will not rotate, further ensuring the stability of the valve.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
