[0004] In order to realize the above -mentioned purpose, the utility model adopts the following technical scheme:

[0005] A stop valve with anti -theft handle, including the valve body, the top of valve body installs the flange plate, and the top of flange plate is connected with the connecting column, the inside of connecting column is connected with valve rod, and the top of valve rod installs handle body,

[0006] The surface of connecting column movably sleeve connects the annular plate, and the top of annular plate is connected with the connecting pipe connected with the bottom of handle body in annular equidistance,

[0007] The surface upper side of connecting column is connected with the annular baffle for blocking the annular plate.

[0008] As a further description of the above technical scheme:

[0009] The inner diameter of the annular plate is smaller than the diameter of the baffle.

[0010] As a further description of the above technical scheme:

[0011] The top of annular plate is annular equidistance and is provided with recess, and the inside bottom of recess is provided with switch, the inner wall of recess is provided with circular plate, and the bottom of circular plate is connected with extrusion rod for extruding switch, and the top of circular plate is connected with connecting rod passing through connecting pipe and being in contact with the bottom of handle body, the surface of annular plate is provided with connecting block, and the inside of connecting block is respectively provided with power supply and buzzer.

[0012] As a further description of the above technical scheme:

[0013] The power supply, switch, and buzzer are connected by a connecting wire.

[0014] As a further description of the above technical solution:

[0015] The connecting block has a slot at its bottom interior.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] In this invention, by connecting the connecting tube to the annular plate and the handle, and by sleeve the connecting tube on the surface of the connecting post, the baffle on the connecting post prevents the handle from being removed after the nut on the handle is disassembled, thus playing an anti-theft role. At the same time, through the switch, spring and compression rod set inside the annular plate, when the connecting tube is damaged, the compression rod moves away from the surface of the switch, thereby allowing the power supply to power the buzzer to make it work, so as to alert people in the vicinity that the handle has been stolen.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2A shut-off valve with an anti-theft handle includes a valve body 1, a flange 2 mounted on the top of the valve body 1, a connecting post 3 connected to the top of the flange 2, a valve stem 4 connected inside the connecting post 3, and a handle body 5 mounted on the top of the valve stem 4; an annular plate 6 is movably sleeved on the surface of the connecting post 3, and a connecting pipe 7 connected to the bottom end of the handle body 5 is equidistantly connected to the top of the annular plate 6; an annular baffle 8 for blocking the annular plate 6 is connected to the upper surface of the connecting post 3. When the valve stem 4 rotates and moves, it can drive the annular plate 6 to rotate and move on the surface of the connecting post 3 through the connecting pipe 7. When the nut on the handle body 5 is removed, because the handle body 5 is connected to the connecting pipe 7, and the annular plate 6 connected to the other end of the connecting pipe 7 is blocked by the baffle 8 on the upper surface of the connecting post 3, it can effectively prevent criminals from stealing the handle.

[0024] Furthermore, the inner diameter of the annular plate 6 is smaller than the diameter of the baffle 8. This is to prevent the inner diameter of the annular plate 6 from being larger than the diameter of the baffle 8, which would cause the annular plate 6 to move off the surface of the baffle 8 and the connecting column 3.

[0025] Furthermore, the top of the annular plate 6 is provided with grooves 9 at equal intervals, and a switch 10 is provided at the bottom of the groove 9. The inner wall of the groove 9 is provided with a circular plate 11, and the bottom of the circular plate 11 is connected to a pressing rod 12 for pressing the switch 10. The top of the circular plate 11 is connected to a connecting rod 13 that passes through the connecting tube 7 and contacts the bottom of the handle body 5. The surface of the annular plate 6 is provided with a connecting block 14, and the inside of the connecting block 14 is respectively provided with a power supply 15 and a buzzer 16. A spring is provided between the bottom of the groove 9 and the circular plate 11. In the initial state, the pressing rod 12 presses the switch 10 to break. After the connecting tube 7 is damaged, the circular plate 11 is pressed by the spring, which can remove the pressing rod 12 at its bottom from the surface of the switch 10, so that the switch 10 can be opened, so that the power supply 15 can supply power to the buzzer 16 to make it work.

[0026] Furthermore, the power supply 15 is connected to the switch 10 and the buzzer 16 via a connecting wire. This allows the power supply 15 to power the buzzer 16 after the switch 10 is turned on, so that the buzzer 16 can alert people in the vicinity that the handle has been stolen.

[0027] Furthermore, a slot 17 is provided at the bottom of the inner part of the connecting block 14, which facilitates the rapid transmission of the sound from the buzzer 16.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
