[0023] Please see Figures 1 to 6This invention provides a technical solution: a self-locking valve-controlled water meter connector, including a meter body 1, which is used to monitor and bill water consumption, and can also perform flow interruption and flow restriction, etc. A connector body 2 is provided on one side of the meter body 1, which is used for installing the meter body 1. A locking member 3 is provided on one side of the watch body 1. The locking member 3 is a ring-shaped part. On the side of the locking member 3 facing away from the watch body 1, multiple sets of sawtooth structures are arranged in a ring at equal intervals. The sawtooth structures are all fan-shaped. A self-locking part 4 is movably sleeved on the side of the watch connector body 2 near the locking member 3. The self-locking part 4 is movably arranged and can be easily moved.

A reset member 9 is fixedly connected to the side of the elastic member 8 near the self-locking part 4. The sliding groove 7 is used for the lateral movement of the reset member 9, so that the self-locking part 4 can move when the locking member 3 is connected to the self-locking part 4, so as to avoid the locking member 3 and the self-locking part 4 getting stuck during installation. At the same time, it is convenient to move the self-locking part 4 when the meter body 1 and the meter connector body 2 are disassembled. The reset member 9 is a ring-shaped member. The size of the reset member 9 is adapted to the sliding groove 7. The side of the reset member 9 near the self-locking part 4 passes through the sliding groove 7 and is fixedly connected to the self-locking part 4. At the same time, the elastic member 8 is used to provide a squeezing force to the reset member 9, so that the reset member 9 can be reset. Since the moving groove 7 and the reset piece 9 are set in a ring, they are prone to rotation during movement. In order to limit the rotation of the reset piece 9 during movement and prevent the self-locking piece 5 on the self-locking part 4 and the saw teeth on the locking part 3 from deviating, multiple sets of limiting slide grooves 10 are arranged in a ring at equal intervals on the inner and outer sides of the moving groove 7. The limiting slide grooves 10 are all set as arc-shaped transverse grooves. The reset piece 9 is provided with a slide piece 11 on the outer side corresponding to the limiting slide groove 10. The slide piece 11 is set as an arc-shaped block. The size of the slide piece 11 is adapted to the limiting slide groove 10. The slide piece 11 is located in the limiting slide groove 10. By setting the limiting slide groove 10 and the slide piece 11, the reset piece 9 can be limited to prevent the reset piece 9 from rotating during movement and ensure that the self-locking piece 5 on the self-locking part 4 and the saw teeth on the locking part 3 are aligned. A movable groove 12 is provided on the side of the connector body 2 near the locking member 3. The movable groove 12 is an annular groove. A limiting member 13 is fixedly connected to the outside of the movable groove 12. The limiting member 13 is also an annular member. An extrusion member 14 is movably disposed inside the movable groove 12. The extrusion member 14 is also an annular member. The dimensions of the extrusion member 14 are adapted to the movable groove 12. The outer diameter of the extrusion member 14 is adapted to the inner diameter of the self-locking part 4. The upper end of the extrusion member 14 on the side away from the locking member 3 is rounded. The movable extrusion member 14 facilitates... The extrusion part 14 is moved, and a groove 15 is provided in the middle of the bottom. The groove 15 is an annular groove, and the inner side of the groove 15 extends through the extrusion part 14. The outer diameter of the groove 15 is larger than the outer diameter of the limiting part 13. The extrusion part 14 is sleeved on the outside of the limiting part 13 through the groove 15. The design of the groove 15 facilitates the lateral movement of the extrusion part 14. A sealing part 16 is fixedly installed on the side of the extrusion part 14 near the watch body 1. The sealing part 16 is made of rubber and can seal the watch body 1 and the watch connector body 2. Meanwhile, multiple sets of extrusion grooves 17 are arranged in a ring inside the self-locking part 4. Each extrusion groove 17 is an arc-shaped groove. An adsorption member 18 is arranged on the outside of the extrusion groove 17. The adsorption member 18 is an annular adsorption member with magnetic material. A pressing member 19 is movably arranged inside the extrusion groove 17. The pressing member 19 is an arc-shaped groove that can adsorb metal material. The adsorption member 18 can adsorb the pressing member 19 by its own adsorption force. An inclined arc-shaped surface is provided on the side of the pressing member 19 near the self-locking part 5. Multiple sets of push members 20 are equidistantly arranged at the bottom of the pressing member 19. Each push member 20 is a vertical member. The bottom surface of each push member 20 is an inclined groove. The bottom of each push member 20 passes through the self-locking part 4 and extends to the upper end of the movable groove 12. The inclined surface of the bottom of the push member 20 fits with the rounded end of the upper end of the extrusion member 14. By pressing the bottom of the push member 20 with the rounded end of the extrusion member 14, it is easy to push the extrusion member 14. A pressing member 21 is movably disposed inside the self-locking part 4. The pressing member 21 is an arc-shaped member. The side of the pressing member 21 near the locking member 3 passes through the middle of the self-locking part 5 and extends to the outside. The side of the pressing member 21 near the locking member 3 is set as an inclined surface corresponding to the sawtooth structure. The side of the pressing member 21 away from the locking member 3 extends into the pressing groove 17. The side of the pressing member 21 away from the locking member 3 is set as an inclined surface. The pressing member 21 fits with the upper arc-shaped surface of the pressing member 19 through the inclined surface. Both sides of the pressing member 21 are provided with side members 22. The self-locking part 4 is provided with a transverse movable groove corresponding to the side members 22. By the pressing member 21 passing through to the outside of the self-locking part 5, when the self-locking part 5 fits with the sawtooth structure, the pressing member 21 can be pushed to one side, so that the pressing member 21 presses the pusher 20 down, so that the sealing member 16 fits more tightly with the body 1.

[0024] During disassembly and assembly, the self-locking part 4 is first moved away from the locking member 3. The self-locking part 4 causes the self-locking member 5 to separate from the serrated structure, so that the self-locking member 5 and the serrated structure no longer self-lock the watch body 1 and the watch connector body 2. The watch connector body 2 can then be removed from the watch body 1. During installation, the watch connector body 2 is aligned with the mounting hole on the watch body 1 and inserted and the knob is turned. When the serrated structure on the locking member 3 is in contact with the self-locking member 5, the self-locking member 5 is squeezed and pushes the self-locking part 4 to move along the watch connector body 2 towards the fixing member 6. After the watch body 1 and the watch connector body 2 are installed, the elastic member 8 pushes the self-locking part 4 through the reset member 9, so that the self-locking member 5 is in contact with the serrated structure, completing the self-locking. At the same time, the downward pressing member 21 is in contact with the inclined surface of the serrated structure and is squeezed, so that the downward pressing member 21 pushes the downward pressing member 19 downward, so that the pusher 20 squeezes the pressing member 14 through the bottom inclined surface, so that the sealing member 16 is more tightly attached to the watch body 1, avoiding leakage.
