Description

Technical Field

[0001] The utility model relates to the technical field of gas meters, in particular to a high-precision and durable gas meter. Background Art

[0002] From the outside of the gas meter, you can only see a digital roller in a small glass window. There are also seven digits on the roller, the first four digits before the decimal point are black, and the last three digits are red. The fuel people use for daily cooking has changed from conventional energy sources such as firewood and coal that waste resources and cause serious pollution to natural gas and coal gas, and even clean energy such as electricity. This is where the gas meter comes into play. Its automatic accumulation function allows those who use natural gas or piped gas to easily know how much gas they have used, so that they can pay according to the number of cubic meters of gas consumed each month. In daily life, a high-precision and durable gas meter is needed.

[0003] When traditional gas meters are installed through pipe docking, they are generally installed in a threaded manner. However, after using threads for installation, gas leakage is inevitable after the gas meter has been used for a long time. Most traditional gas meters do not have an effective sealing structure, which will cause the gas meter to jump and be inaccurate, thereby affecting the normal use of the gas meter. In addition, most traditional gas meters do not have a structure to effectively protect the display panel. When objects in the external environment violently hit the display panel, the display panel will be damaged, thereby reducing the overall service life of the gas meter and affecting the normal use of the gas meter.

[0004] Therefore, those skilled in the art provide a high-precision and durable gas meter to solve the problems raised in the above background technology. Utility Model Content

[0035] The above working principle: when the gas meter body 1 needs to be used, it is only necessary to first fix the docking cover 2 and the connecting pipe 5 through threads. After the installation between the docking cover 2 and the connecting pipe 5 is completed, the sealing assembly is used to improve the sealing between the docking cover 2 and the connecting pipe 5. At this time, it can effectively prevent the appearance of gaps between the docking cover 2 and the connecting pipe 5, which may cause gas leakage, etc., and effectively improve the accuracy of the gas meter body 1. When the display panel 12 needs to be protected, it is only necessary to fix the position of the protective assembly through the fixing assembly. At this time, the display panel 12 can be effectively protected by the protective assembly, thereby effectively extending the service life of the gas meter body 1, improving the practicality of the gas meter body 1, and saving time and effort.

[0036] In order to effectively improve the sealing between the docking cover 2 and the connecting pipe 5, the sealing component includes an inflatable bag 16 fixedly connected to the inner wall of the docking cover 2, the interior of the inflatable bag 16 is connected to the air inlet pipe 17, the air inlet end of the air inlet pipe 17 extends to the outside of the docking cover 2 and is connected to the balloon 18, the interior of the air inlet pipe 17 is provided with a one-way valve, the interior of the inflatable bag 16 is connected to the exhaust pipe 19, and the air outlet end of the exhaust pipe 19 is provided with a sealing cover 20. When it is necessary to install the docking cover 2 and the connecting pipe 5, it is only necessary to first fix the docking cover 2 and the connecting pipe 5 through threads. When the docking cover 2 and the connecting pipe 5 are connected, After the installation is completed, pinch the balloon 18 again. At this time, the gas inside the balloon 18 will be transmitted to the inside of the inflatable bag 16 through the air inlet pipe 17. When the inflatable bag 16 is fully inflated, the inflatable bag 16 will contact the outside of the connecting pipe 5. At this time, the inflatable bag 16 can be used to effectively improve the sealing between the docking cover 2 and the connecting pipe 5, thereby avoiding gas leakage after the installation between the docking cover 2 and the connecting pipe 5 is completed, effectively improving the accuracy of the gas meter body 1. When the inflatable bag 16 is not needed, just open the sealing cover 20. At this time, the gas inside the inflatable bag 16 will be discharged through the exhaust pipe 19.

[0037] Taking into account that the display panel 12 needs to be protected when the gas meter body 1 is in use, so as to effectively extend the service life of the gas meter body 1, the protection component includes a connecting frame 7 fixedly connected to the upper surface of the gas meter body 1, the interior of the connecting frame 7 is fixedly connected to a fixing rod 21, the exterior of the fixing rod 21 is fixedly connected to a spiral spring 22, the other end of the spiral spring 22 is fixedly connected to a rotating sleeve 23, the exterior of the rotating sleeve 23 is fixedly connected to a protective cover 4 through an L-shaped plate 8, the front end surface of the protective cover 4 is fixedly connected to the mounting plate 10 through a front plate 9, the front end surface of the gas meter body 1 is symmetrically provided with positioning card frames 13, the interiors of the two positioning card frames 13 are provided with guide grooves for the movement of the protective cover 4, when the display panel 12 needs to be protected, it is only necessary to press the protective cover 4 first, at this time the protective cover 4 will drive the L-shaped plate 8 to move synchronously, and the L-shaped plate 8 will then The rotating sleeve 23 is driven to rotate synchronously. During the rotation of the rotating sleeve 23, the volute spring 22 will be stretched, and the protective cover 4 will also drive the mounting plate 10 to move synchronously. When the protective cover 4 is fully closed, the position of the protective cover 4 is fixed by the fixing component. At this time, the display panel 12 can be effectively protected by the protective cover 4, thereby preventing the display panel 12 from being damaged by impact, etc., effectively extending the service life of the gas meter body 1. When the display panel 12 needs to be checked or debugged, it is only necessary to cancel the fixing effect of the protective cover 4 through the fixing component. At this time, the volute spring 22 is reset, driving the rotating sleeve 23 to rotate synchronously. The rotating sleeve 23 then drives the L-shaped plate 8 and the protective cover 4 to move synchronously. When the protective cover 4 is fully opened, the user can check and debug the display panel 12.

[0038] In order to effectively fix the protective cover 4 so that the protective cover 4 can effectively protect the display panel 12, the fixing assembly includes a fixing frame 11 fixedly connected to the front end surface of the gas meter body 1, and a guide groove for the movement of the mounting plate 10 is provided inside the fixing frame 11.

When the protective cover 4 needs to be fixed, just press the insertion rod 26 first. At this time, the insertion rod 26 will squeeze the telescopic rod 25 and the return spring 27, and then plug the mounting plate 10 into the inside of the fixed frame 11. At this time, the mounting plate 10 will drive the insertion rod 26 to move synchronously. When the mounting plate 10 drives the insertion rod 26 to move into the guide grooves on both sides of the outer wall of the fixed frame 11, the return spring 27 resets and drives the insertion rod 26 to move synchronously. When the insertion rod 26 is inserted into the guide grooves on both sides of the outer wall of the fixed frame 11, the fixed frame 11 and the mounting plate 10 can be fixed. At this time, the position of the protective cover 4 can be fixed, so that the protective cover 4 can effectively protect the display panel 12.

[0039] In order to further improve the sealing between the docking cover 2 and the connecting pipe 5, a rubber sealing ring 6 is symmetrically provided on the upper surface of the gas meter body 1. When the docking cover 2 and the connecting pipe 5 are installed, the bottom of the docking cover 2 will contact the upper surface of the rubber sealing ring 6. At this time, the rubber sealing ring 6 can further improve the sealing between the docking cover 2 and the connecting pipe 5, thereby further improving the accuracy of the gas meter body 1.
