Description

Technical Field

[0001] This utility model relates to the field of gas meter manufacturing technology, and in particular to an NB diaphragm gas meter that is easy to assemble quickly. Background Technology

[0002] In the development of gas meters, NB diaphragm gas meters have gradually replaced traditional mechanical gas meters and become the mainstream metering instrument on the market due to their advantages such as intelligent metering, efficient management, and no need for manual meter reading. While achieving intelligent functions, the addition of components such as the main control board and battery compartment has increased the complexity of assembly. Therefore, it is necessary to further simplify the steps and processes to achieve high-efficiency assembly, preparing for future unmanned assembly using industrial robots operating robotic arms.

[0003] Existing NB diaphragm gas meters, which are easy to assemble quickly, have obvious defects in installation and maintenance. They use traditional bolt fixing methods, which cannot achieve quick snap-fit ​​assembly and disassembly. At the same time, they lack an integrated positioning structure, which requires repeated adjustments to the alignment during the installation process. This dual structural defect not only reduces installation efficiency, but may also cause safety hazards due to loose bolts, or delay maintenance due to inconvenient assembly and disassembly, ultimately affecting the assembly quality and reliability of the gas meter.

The NB diaphragm gas meter includes a first mounting component 1, a second mounting component 2, and a battery component 3.

[0028] Through the coordinated operation of the first installation component 1 and the second installation component 2, the installation efficiency and positioning accuracy are significantly improved, effectively solving the problems of cumbersome disassembly and assembly and difficult alignment. This not only ensures the reliability of the equipment connection but also avoids the time loss caused by repeated adjustments. At the same time, it realizes the convenient operation of 'alignment and installation' and a stable lock, greatly improving the assembly quality and maintenance convenience of the gas meter.

[0030] The support column 13, the first positioning rod 15, and the limiting buckle 12 can quickly position the first mounting component 1 during the installation process, thereby improving the installation efficiency of its main body.

[0031] Specifically, the second mounting component 2 is disposed on top of the first mounting component 1, including a second sealing member 22 embedded on top of the first sealing member 11, an upper cover 21 is disposed on top of the second sealing member 22, and a support kit 23 is fixed on the inner wall of the upper cover 21.

[0032] Specifically, the battery assembly 3 is disposed in the inner cavity of the first mounting assembly 1, including a battery compartment 32 disposed in the inner cavity of the first sealing member 11, and a battery compartment fixing limit rod 31 is provided on one side of the battery compartment 32.

[0033] The battery compartment fixing limit rod 31 can limit the fixed position of the battery compartment 32 during the installation process. By cooperating with the first sealing element 11, it can form an installation guide rail, thereby providing a better installation positioning effect during the installation process. Example

[0034] Reference Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the first sealing element 11 includes a convex sealing surface 11-1, and a sealing groove 11-2 is provided on the inner wall of the convex sealing surface 11-1. A positioning bracket 14 is fixed on the inner side of the sealing groove 11-2.

[0036] The positioning bracket 14 can quickly guide and position the main board component 17 during the installation process.

[0037] Specifically, the main board component 17 includes an electronic control main board 17-1 disposed on the outside of the positioning bracket 14. An MCU 17-6 is fixed on one side of the electronic control main board 17-1, and a first photoelectric sensor 17-2, a first Hall sensor 17-3, a second photoelectric sensor 17-4, and a second Hall sensor 17-5 are respectively fixed on one side of the electronic control main board 17-1.

[0038] The MCU17-6 uses the STM32U0 model from STMicroelectronics. The pins define functions and connect to the sampling components. The first photoelectric sensor 17-2, the first Hall sensor 17-3, the second photoelectric sensor 17-4, and the second Hall sensor 17-5 are designed as two groups of sampling components, A and B. While completing the sampling work, they also have the function of accommodating various abnormal situations, which improves the sampling reliability. Correspondingly, the counter signal disk of the corresponding sampling area is also set as a black and white rotary disk or a fixed steel magnet, depending on the sampling method, so as to work normally with the electronic control motherboard 17-1.

[0039] Specifically, the second seal 22 includes a concave sealing surface 22-1, and a sealing rib 22-2 is provided on the inner side of the concave sealing surface 22-1.

[0040] The sealing groove 11-2 cooperates with the sealing rib 22-2, and the sealant is automatically injected in advance to ensure the sealing of the joint, and it can be easily fixed by the top-to-bottom installation method of the convex sealing surface 11-1.

[0041] Specifically, a second positioning rod 16 is fixed to the inner wall of the first sealing element 11, and a support column 13 is fixed to the inner wall of the first sealing element 11.

[0042] When the device needs to be assembled, the user first holds the main board component 17 with a robotic arm and then sends it into the inner cavity of the convex sealing surface 11-1. During this process, the positioning bracket 14 guides it, and the main board component 17 is quickly positioned and installed by the cooperation of the positioning hole on the surface of the main board component 17, the first positioning rod 15, the limit buckle 12 and the support column 13.

[0043] After the positioning and installation are completed, sealant can be injected into the sealing groove 11-2 first, and then the second installation component 2 can be spliced ​​with the first installation component 1. The support kit 23 set inside the upper cover 21 can play a guiding role. The concave sealing surface 22-1 is fitted and snapped with the convex sealing surface 11-1 to form the first seal. The sealing rib 22-2 and the inner cavity of the sealing groove 11-2 are filled with sealant, so that the sealing rib 22-2 presses the sealant into the sealing groove 11-2 to form the second seal.
