[0002] The vertical base meter for a heat meter is an important component of the heat meter. It is usually used to support and fix the heat meter to ensure that it can stably and accurately measure the heat in the heat exchange loop.

[0003] As an important measuring instrument for heat metering trade settlement, the measurement accuracy of the heat meter is crucial. As an important part of the heat meter, if the vertical base meter becomes loose, it will directly affect the installation stability of the heat meter, and may then lead to deviations in the measurement results. Therefore, the anti-loosening design can ensure that the heat meter maintains a stable posture during the measurement process, thereby improving the measurement accuracy. Summary of the Invention

[0004] The purpose of the utility model is to provide a vertical base meter for a heat meter with anti-loosening function and easy disassembly and assembly in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be realized by the following technical solutions: A vertical base meter for a heat meter with anti-loosening function, characterized in that it includes a base meter main body with a water inlet end and a water outlet end. Both ends of the base meter main body are provided with connection parts, and connection pipes are fixed on the connection parts. The connection parts are provided with through holes, and a clamping cavity is arranged in the through holes. An installation groove is formed on the connection parts. A limiting pull ring is arranged in the clamping cavity. A limiting guide plate is arranged on the limiting pull ring. The end of the limiting guide plate abuts against the connection pipe. A positioning ring is arranged on the connection pipe. A fixing hook is fixed on the positioning ring. A limiting card slot for clamping and fixing the fixing hook is arranged at the top of the installation groove. The fixing hook abuts against the top of the limiting guide plate.

[0006] In the above-mentioned vertical base meter for a heat meter with anti-loosening function, a cable is arranged on the limiting pull ring.

[0007] In the above-mentioned vertical base meter for a heat meter with anti-loosening function, a guiding strip is arranged on the connection pipe, a guiding groove is arranged on the positioning ring, and a locking bolt is also arranged on the positioning ring.

[0008] Compared with the prior art, the vertical base meter for a heat meter with anti-loosening function of the present utility model prevents the rotational looseness caused by unstable connection of the columnar base meter by arranging limiting card slots at both ends to fix the fixing hooks. The detachable limiting pull ring guides the fixing hook to be clamped in the limiting card slot. By removing the limiting pull ring, the fixing hook can be unhooked, and thus the disassembly can be completed. It has the advantages of easy disassembly and assembly.

Detailed implementation manners

[0012] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0013] As Figure 1 、 2 shown, the columnar base meter of the anti-loosening heat meter includes a main body 3 of the base meter provided with a water inlet end 4 and a water outlet end 2. Both ends of the main body 3 of the base meter are provided with connecting parts 9, and connecting pipes 5 are fixed on the connecting parts 9. The connecting parts 9 are provided with through holes 10, and clamping cavities 12 are arranged in the through holes 10. Mounting grooves 17 are formed on the connecting parts 9. A limiting pull ring 11 is arranged in the clamping cavity 12. A limiting guide plate 16 is arranged on the limiting pull ring 11. The end of the limiting guide plate 16 abuts against the connecting pipe 5. A positioning ring 1 is arranged on the connecting pipe 5. A fixed hook 15 is fixed on the positioning ring 1. A limiting card slot 14 for clamping the fixed hook 15 is arranged at the top of the mounting groove 17. The fixed hook 15 abuts against the top of the limiting guide plate 16. During installation, the limiting pull ring 11 is installed in the clamping cavity 12 so that the limiting guide plate 16 abuts closely against the connecting pipe 5. Then, the positioning ring 1 is moved to make the hook engage with the limiting card slot 14 for positioning. During disassembly, the limiting pull ring 11 is pulled, and the hook moves downward to disengage, thus completing the conventional disassembly.
