The above application document sets a reverse valve so that when the user turns the water meter around without authorization, the tap water flowing into the water meter through the water outlet end cannot enter the water inlet end, thereby blocking the flow of water, preventing users from stealing water, and facilitating the management of water suppliers. However, in actual use, it is impossible to solve the problem that users secretly tamper with the position of the pointer on the water meter, thereby changing the reading. Therefore, a multifunctional anti-theft water meter is needed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1

[0021] See also Figure 1-3A multifunctional anti-theft water meter comprises a case 1, the case 1 is in the shape of a hollow cylinder with one side being a plane, the case 1 is movably connected with a flange 2, an axial flow check valve 3 is arranged inside the flange 2, a closing device 4 is arranged inside the flange 2, an anti-theft device 5 is arranged inside the case 1, the anti-theft device 5 comprises a cover 51, the cover 51 is movably connected with the case 1, an air pressure chamber 52 is provided in the inner wall of the case 1, the air pressure chamber 52 is connected with an air bag 53, a slide plate 54 is slidably connected to the inner wall of the air pressure chamber 52, a rack 55 is fixedly connected to the outer wall below the slide plate 54, one end of a spring 56 is fixedly connected to the lower side of the slide plate 54, the elastic force of the spring 56 is greater than the friction force between the slide plate 54 and the inside of the air pressure chamber 52 and the gravity of the slide plate 54, and the elastic force is set to ensure that when the air bag 53 is not squeezed, the spring 56 can push the slide plate 54 to move, so that the subsequent effect can be carried out smoothly, and the other end of the spring 56 is fixedly connected to the On the inner wall of the air pressure chamber 52, the inner wall of the watch case 1 is rotatably connected with a rotating shaft 57, and a trapezoidal latch is provided on the outer wall of the rotating shaft 57, and the rotating shaft 57 is meshed with the rack 55 through the latch. By providing the latch on the rotating shaft and meshing with the rack, the rotating shaft can rotate when the rack moves, so that the expected effect can be achieved. The rotating shaft 57 is fixedly connected with a dial 58, and the rotating shaft 57 is rotatably connected with a baffle 59, and the dial 58 and the baffle 59 are 90 degrees to each other, and the dial 5 The initial position of 8 is parallel to the watch cover 51. By setting the positions of the dial and the baffle, it is ensured that when the dial is rotated to fit the inner wall of the case, the baffle can just block the opening on the top of the case to achieve an anti-theft effect. By opening the watch cover, the slide plate moves upward under the action of spring 1, thereby driving the rack to move upward, and the shaft is driven to rotate counterclockwise through the teeth on the shaft, thereby driving the dial and the baffle to rotate, achieving the effect of blocking the dial through the baffle to prevent the data on the dial from being tampered with.

[0022] During use, when the user wants to change the direction of the pointer on the dial by opening the watch cover 51, after the user opens the watch cover 51, the airbag 1 53 is not squeezed, and the gas in the air pressure chamber 52 can enter the airbag 1 53 to keep the air pressure stable, so the spring 1 56 rebounds, pushes the slide plate 54 to move upward, and drives the rack 55 to move upward. During the upward movement of the rack 55, the outer teeth of the rotating shaft 57 drive the rotating shaft 57 to rotate counterclockwise, thereby driving the dial 58 and the baffle 59 to rotate counterclockwise at the same time, so that the dial 58 rotates to a position that fits the inner wall of the watch case 1, and the baffle 59 rotates to the sealing position. When the operator needs to open the watch cover 51 to inspect the watch dial, he only needs to squeeze the airbag 53 by external force after removing the watch cover 51, so that the airbag 53 cannot expand, thereby ensuring that the slide plate 54 cannot move under the rebound force of the spring 56, thereby making the rack 55 unable to move and the shaft 57 unable to rotate, thereby ensuring that the positions of the watch dial 58 and the baffle 59 do not change, thereby achieving the effect of enabling the operator to perform normal inspection.

[0023] Embodiment 2

[0024] See also Figure 1-5 On the basis of the first embodiment, the closing device 4 includes an air pressure tube 41, which is arranged in the inner wall of the flange 2, and a slide 42 is slidably connected to the inner wall of the air pressure tube 41. The surface material of the slide 42 is soft rubber, and the outer wall of the slide 42 fits the inner wall of the air pressure tube 41. By setting the surface material of the slide and the setting of the fit between the outer wall of the slide and the inner wall of the air pressure tube, it is ensured that the slide and the inner wall of the air pressure tube are tightly fitted without a gap, so as to prevent the gas inside the air pressure tube from flowing away through the gap between the slide and the air pressure tube. The slide 42 is fixedly connected to a connecting rope 43, and one end of the slide 42 close to the connecting rope 43 is fixedly connected to a spring 2 44, and the connecting rope 43 is located at the lower end of the slide 42, and the connecting rope 43 and the spring 44 are fixedly connected. The two 44 are not on the same horizontal plane. By setting the position of the connecting rope, it is ensured that the connecting rope does not contact the spring two during use, so as to prevent the connecting rope and the spring two from interfering with each other. The other end of the spring two 44 is fixedly connected to the inner wall of the air pressure tube 41, and the end of the connecting rope 43 away from the sliding plate 42 is fixedly connected to the triangular block 45. The triangular block 45 is slidably connected to the inner wall of the flange 2. The air pressure tube 41 is connected to the air bag two 46. By moving the watch case, the sliding plate slides under the action of the spring two, thereby pulling the connecting rope, so that the connecting rope pulls the triangular block to move upward, thereby limiting the axial flow check valve, so that the axial flow check valve is closed, so that the water flow cannot flow normally, so as to prevent users from stealing water.

[0025] During use, based on the first embodiment, when the user wants to modify or reversely install the watch case 1 by removing it, after the watch case 1 is removed, the airbag 2 46 is not affected by external forces, and the gas inside the air pressure tube 41 can pass into the airbag 2 46. At this time, the slide 42 moves toward the direction close to the airbag 2 46 under the drive of the spring 2 44, and pulls the connecting rope 43 during the movement, so that the connecting rope 43 pulls the triangular block 45, so that the triangular block 45 moves upward, thereby squeezing the axial flow check valve 3, so that the axial flow check valve is limited by the triangular block 45 and cannot be opened. At this time, the water pipe cannot discharge water normally due to the closing of the axial flow check valve, and the user cannot use water normally, thereby preventing the user from stealing water.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
