The wall of the through hole 23 is provided with a second vertical tooth 24 that matches the first vertical tooth 14. A connecting piece 25 is provided around the through hole 23. The inner side surface of the connecting piece 25 is provided with a second horizontal tooth 26 that matches the first horizontal tooth 13. The connecting piece 25 can be reversibly deformed in a direction away from the connecting sleeve 12. In this embodiment, the housing 20 can be made of plastic material, the upper end of the connecting piece 25 is connected to the sleeve-fitting portion 21, and the lower end of the connecting piece 25 is suspended, so that the lower end of the connecting piece 25 can be reversibly deformed within a certain deformation range, and the second horizontal tooth 26 is provided at the lower end of the connecting piece 25. When the through hole 23 is fitted with the connecting sleeve 12, the fitting part 21 is fitted from top to bottom to the outside of the connecting sleeve 12. At this time, the connecting piece 25 is deformed outward, the second horizontal tooth 26 can slide relative to the first horizontal tooth 13, and the second vertical tooth 24 cooperates with the first vertical tooth 14 to prevent the fitting part 21 from rotating relative to the connecting sleeve 12.

Specifically, the threaded fastener is a machine screw, and the machine screw can play a good tightening role. Preferably, the locking seat 27 also includes a baffle located on the outside of the nut positioning groove 28. In the present embodiment, the baffle is an arc-shaped panel on the outer side of the sleeve 21. The baffle is provided with a through hole 29 for the threaded fastener to pass through. When the connecting piece 25 is locked to the connecting sleeve 12, the end of the machine screw is flush with the through hole 29 or is located in the through hole 29, thereby better protecting the fastener and preventing the fastener from loosening due to touch. It is difficult to disassemble and open except with professional tools, which can reduce the possibility of human damage.

The sensor placement chamber 61 is used to place the sensor. The sensor placement chamber 61 is arranged at the notch of the connecting sleeve 12 and protrudes toward the through hole 23, so that the sensor is close to the counter on the mechanical water meter to sense the rotation of the counter pointer. For example, the counter pointer may be provided with a magnetic core that rotates with the pointer, and the sensor senses the rotation of the pointer. The battery placement chamber 62 is arranged away from the through hole 23 to prevent the battery placement chamber 62 from hitting the clamping cover of the water meter. The battery placement chamber 62 is used to place devices such as batteries. The device placed in the chamber 60 also includes a processor, which is electrically connected to the sensor and the battery respectively. The battery provides power.

The processor can be placed in the battery placement chamber 62 or the connection chamber 63, and the buckle 64 and the notch 65 are used to limit the wires connecting the processor, the sensor, and the battery.

[0034] In this embodiment, the number of sensor placement cavities 61 is two, which improves accuracy. The processor can process the sensing data of the two sensors, for example, calculate the average of the pointer rotation angles measured by the two sensors and then calculate the water consumption. The two sensor placement cavities 61 protrude toward the through hole 23 and protrude downward, respectively, closer to the counter of the water meter. A U-shaped groove is formed between the two sensor placement cavities 61.

[0035] The cover 30 closes the upper opening, thereby protecting the components in the chamber 60. Specifically, after all components are placed, the cover 30 can be welded to the upper opening, thereby preventing water, such as rainwater, from entering the chamber 60 from above, thereby improving the waterproof level.

[0036] The movable cover 40 is hinged on the sleeve part 21, and the movable cover 40 rotates along the hinge to open or close the through hole 23. In this embodiment, the first end of the movable cover 40 is provided with a column 41, and the column 41 is hinged with the hinge hole 22 on the sleeve part 21, and the hinge hole 22 is arranged at a position of the sleeve part 21 away from the chamber 60, and the second end of the movable cover 40 is W-shaped, which cooperates with the two sensor placement cavities 61 and the U-shaped groove formed by them.

[0037] Furthermore, the battery placement cavity 62 is convex downward to form a semi-cylindrical accommodating cavity, and a side opening 66 is provided on one side of the battery placement cavity 62, and the side opening 66 is opened and closed by the side cover 50. The battery can be conveniently disassembled and assembled through the side opening 66.
