[0002] A gas meter is a measuring device used to measure the amount of gas (such as natural gas, liquefied petroleum gas, etc.) used in homes, businesses, or industrial sites. Its core function is to record the cumulative amount of gas consumed so that gas companies can charge based on the usage.

[0003] While existing gas meters can achieve sealing through gaskets, their sealing structure is simple and cannot be improved to expand the sealing performance. Furthermore, the gaskets are exposed to the outside and come into contact with oil fumes for a long time, which can easily lead to a shortened service life. Utility Model Content

[0004] This utility model relates to a gas meter with waterproof and corrosion-resistant protection functions, which solves the problems of existing gas meters, which, although they can achieve sealing through sealing gaskets, have a simple sealing structure and cannot expand the sealing performance through structural improvements. In addition, the sealing gaskets are exposed to the outside and come into contact with oil fumes for a long time, which can easily lead to a shortened service life.

[0005] This utility model provides a gas meter with waterproof and corrosion-resistant protection functions, specifically including: a lower gas meter shell; a gas meter upper shell is fixed to the lower gas meter shell, a cover is welded to the bottom of the upper gas meter shell, a plug is welded to the top of the lower gas meter shell, the plug is inserted into the inside of the cover, the outer wall of the plug is in contact with the inner wall of the cover, and a U-shaped stop is welded on the plug, the top surface of the stop is in contact with the bottom surface of the cover.

[0006] Furthermore, four fixing screws are inserted into the upper shell of the gas meter, and all four fixing screws pass through the lower shell of the gas meter. Each fixing screw has four auxiliary slots equidistantly spaced around its central axis at one end below. The four fixing screws are threaded onto a stop seat. Four concave seat bodies are welded to the bottom end face of the stop seat. Each seat body has a conical protrusion welded on it. When the four fixing screws are tightened, the four protrusions are inserted into the lower end of the four fixing screws. Under the pressure of the four protrusions, the auxiliary slots at the lower end of the four fixing screws are in an open state.

[0007] Furthermore, the adjustment points of the four fixing screws are all hexagonal structures, and each fixing screw adjustment point has an adjustment groove, which is a hexagonal groove structure.

[0008] Furthermore, a sealing gasket is attached to the top surface of the connector, and when the four fixing screws are tightened, the top surface of the sealing gasket makes elastic contact with the top surface of the inner wall of the cover.

[0009] Furthermore, a display screen is installed on the upper casing of the gas meter, and a cover plate is mounted on the upper casing of the gas meter via a hinge, which covers the display screen.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] This utility model proposes a gas meter with waterproof and corrosion-resistant protection functions, including: a lower gas meter shell 1; a gas meter upper shell 2 is fixed to the lower gas meter shell 1, a cover 201 is welded to the bottom of the upper gas meter shell 2, and a plug-in seat 101 is welded to the top of the lower gas meter shell 1. The plug-in seat 101 is inserted into the inside of the cover 201, and the outer wall of the plug-in seat 101 contacts the inner wall of the cover 201. The insertion of the plug-in seat 101 into the cover 201 can improve the sealing performance at the connection between the lower gas meter shell 1 and the upper gas meter shell 2; a U-shaped stop 102 is welded on the plug-in seat 101, and the top surface of the stop 102 contacts the bottom surface of the cover 201. During use, the contact between the top surface of the stop 102 and the bottom surface of the cover 201 can further improve the sealing performance at the connection between the lower gas meter shell 1 and the upper gas meter shell 2.

[0031] The gas meter upper casing 2 has four fixing screws 301 inserted into it. All four fixing screws 301 pass through the gas meter lower casing 1. Each fixing screw 301 has four auxiliary slots 304 equidistantly spaced around its central axis at one end below. The four fixing screws 301 are threaded onto the stop seat 102. The bottom surface of the stop seat 102 is welded with four concave seat bodies 302. Each seat body 302 has a conical protrusion 303 welded on it. When the four fixing screws 301 are tightened, the four protrusions 303 are inserted into the lower end of the four fixing screws 301. Under the pressure of the four protrusions 303, the auxiliary slots 304 at the lower end of the four fixing screws 301 are open. When the four fixing screws 301 are open, the probability of the four fixing screws 301 loosening is reduced.

[0032] The adjustment points of the four fixing screws 301 are all hexagonal structures, and each fixing screw 301 has an adjustment groove 305. The adjustment groove 305 is a hexagonal groove structure. When disassembling the fixing screws 301, a conventional wrench can be used to clamp the fixing screw 301 at the adjustment point for disassembly, or an Allen wrench can be used to insert into the adjustment groove 305 for disassembly, which provides high disassembly flexibility.

[0033] A sealing gasket 103 is attached to the top surface of the plug-in 101. When the four fixing screws 301 are tightened, the top surface of the sealing gasket 103 makes elastic contact with the top surface of the inner wall of the cover 201. The elastic contact between the top surface of the sealing gasket 103 and the top surface of the inner wall of the cover 201 can improve the sealing performance at the connection between the lower housing 1 and the upper housing 2 of the gas meter. Since the sealing gasket 103 is located inside the cover 201 and does not come into contact with oil fumes, it will not be corroded, thus improving the sealing effect and service life of the sealing gasket 103.

[0034] The gas meter upper casing 2 is equipped with a display screen 203. A cover plate 204 is mounted on the gas meter upper casing 2 via a hinge. The cover plate 204 covers the display screen 203. By covering the display screen 203 with the cover plate 204, oil stains can be prevented from coming into contact with the display screen 203, thus preventing the inability to accurately observe the numbers on the display screen 203 due to the influence of oil stains. When observing, the cover plate 204 can be manually lifted.

[0035] Example 2, based on Example 1, such as Figures 1 to 6 As shown, two connecting seats 202 for connecting to gas pipelines are welded to the top of the gas meter upper shell 2. Two snap-fit ​​seats 401 are welded to the top surface of the gas meter upper shell 2. Two locking screws 403 are inserted into each snap-fit ​​seat 401. A snap-fit ​​block 402 is fixed to each snap-fit ​​seat 401 by the two locking screws 403. The snap-fit ​​block 402 and the snap-fit ​​seat 401 are fasteners for the gas pipeline. During use, after the gas pipeline is fixed by the snap-fit ​​block 402 and the snap-fit ​​seat 401, the gas pipeline can be prevented from being subjected to force, which would affect the sealing performance between the gas pipeline and the connecting seat 202.

[0036] The working principle of this embodiment is as follows: When assembling the lower casing 1 and the upper casing 2 of the gas meter, the plug-in socket 101 on the lower casing 1 is inserted into the cover 201 of the upper casing 2, and then fixed with four fixing screws 301; when connecting the pipes, the two gas pipes are connected to the two connecting seats 202, and the two snap-fit ​​seats 401 and the two snap-fit ​​blocks 402 are snapped onto the gas pipes. Finally, the two snap-fit ​​seats 401 and the two snap-fit ​​blocks 402 are fixed with four locking screws 403; when observing, the display screen 203 can be manually opened to observe.
