[0023] The end face locking piece includes a central flange 5 and a plurality of magnetic trigger structures with magnetic properties. A plurality of mounting screws 6 are evenly connected to both sides of the central flange 5. Mounting openings are provided at positions corresponding to the positions of each mounting screw 6 on the first connecting flange 2 and the second connecting flange 4. A mounting nut 7 is threadedly connected to each mounting screw 6. A cavity is provided inside the mounting screw 6, and a metal rough slider 10 that can be attracted by a magnet is slidably connected in the cavity. A transition chamfer 11 is provided on one end of the metal rough slider 10 close to the central flange 5. A thin connecting rod 12 is connected to one end of the transition chamfer 11 away from the metal rough slider 10. A first non-magnetic spring 16 is connected to one end of the metal rough slider 10 away from the transition chamfer 11. One end of the first non-magnetic spring 16 away from the thin connecting rod 12 is connected to the end of the cavity. A plurality of snap-fit ​​units that cooperate with the transition chamfer 11 are also evenly provided on the mounting screw 6. When the ultrasonic water meter body 1 is installed and connected to the water pipe to be tested through the end face locking piece in the present application, it is not only convenient for the operator to install the ultrasonic water meter body 1, but also the installed and fixed ultrasonic water meter body 1 can be anti-theft locked through a hidden lock, effectively preventing the ultrasonic water meter body 1 from being stolen after installation.

[0024] Reference Figure 2 The buckle unit includes a pin rod 13, a positioning slider 14 is connected to the side wall of the pin rod 13, the mounting screw 6, the mounting nut 7, the pin rod 13 and the positioning slider 14 are all made of non-ferromagnetic materials, the positioning slider 14, the mounting screw 6, the mounting nut 7, the pin rod 13 and the positioning slider 14 are preferably made of non-magnetic steel material, and a second non-magnetic spring is connected to the end of the positioning slider 14, and the first non-magnetic spring and the second non-magnetic spring are both non-magnetic stainless steel springs.

[0025] The side wall of the mounting screw 6 is provided with access holes corresponding to the position of each buckle unit, and the bayonet rod 13 is slidably connected to the corresponding access holes; the inside of the mounting screw 6 is provided with a movable groove connected to the access holes and adapted to the positioning slider 14 at the position corresponding to each access hole, and the positioning slider 14 is slidably connected to the corresponding movable groove; the end of the second non-magnetic spring away from the positioning slider 14 is connected to the end of the movable groove.
