Description

Technical Field

[0001] This utility model relates to the field of natural gas metering equipment technology, and in particular to a natural gas metering device. Background Technology

[0002] Natural gas, as a clean and efficient energy source, has been widely used in residential homes, commercial establishments, and industrial sectors. In residential homes, natural gas metering devices are the core equipment for accurately measuring natural gas consumption and ensuring fair billing between gas companies and users. Their installation method, ease of use, and metering accuracy directly affect users' daily life experience and the safety of gas supply. With the improvement of living standards, home kitchen decoration styles are becoming increasingly diverse, placing higher demands on the adaptability, space utilization, and aesthetics of kitchen equipment installation. However, existing natural gas metering devices have significant limitations in installation methods, specifically: I. Currently, most mainstream natural gas metering devices on the market, namely traditional gas meters, only support a single "wall-mounted" installation method. These gas meters have mounting ears on the back or sides of the meter body. The mounting ears are fixed to the wall by drilling holes and inserting expansion bolts, thus securing the gas meter. This single installation method has the following problems: Insufficient space occupation and aesthetics: Wall-mounted installation requires the gas meter to protrude from the wall. For users with small kitchen spaces or those who pursue "embedded" or "integrated" decoration styles, the gas meter protruding from the wall will occupy extra operating space, which will disrupt the overall coordination and aesthetics of the kitchen decoration and make it difficult to meet the needs of modern families for refined utilization and aesthetics of kitchen space.

[0003] Installation scenarios are limited: Some kitchens have special wall materials, such as marble walls, glass walls, or walls that are already covered with decorative panels. If wall-mounted installation is used, holes need to be drilled in the wall, which may not only damage the wall material and affect the decorative effect, but may also cause the gas meter to be unstable due to the limitations of the wall structure, such as hollow walls not being able to provide sufficient load-bearing capacity. In addition, some users combine gas pipes with cabinets to optimize the kitchen layout. Traditional wall-mounted gas meters cannot be adapted to installation scenarios with pre-reserved grooves in cabinets or walls, resulting in a serious lack of installation flexibility.

[0004] Second, kitchen environments contain a large amount of oil fumes and grease. Traditional gas meter displays are directly exposed to the external environment. During daily use, oil fumes and grease easily adhere to the display surface, forming stains that are difficult to clean. This problem leads to the following drawbacks: Difficulty in reading: When oil stains cover the display screen, they will obscure the metering information such as numbers and symbols on the screen, making it difficult for users to clearly read the gas consumption data. This may lead to gas outages due to the inability to keep track of the remaining gas, affecting normal gas usage.

[0005] Increased risk of display screen damage: Users may use a damp cloth or cleaning agent to wipe the oil stains on the display screen surface. If the cleaning method is improper, such as wiping vigorously or using corrosive cleaning agents, it can easily cause scratches on the display screen surface, peeling off the coating, or even damage to the internal circuitry of the display screen due to moisture, thus shortening the service life of the gas meter.

[0006] Hygiene risks: Long-term accumulation of oil stains on the screen surface can easily breed bacteria, creating unsanitary corners that do not meet the hygiene and cleaning needs of a family kitchen.

[0007] To address these shortcomings, we have proposed a natural gas metering device. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing a natural gas metering device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a natural gas metering device, comprising a meter body and an embedded mounting plate, wherein a display screen is fixedly installed on one side surface of the meter body, and a dirt-proof cover is hinged to one side of the display screen via a hinge; an assembly hole is provided through the surface of the embedded mounting plate; a threaded hole is provided on the side surface of the embedded mounting plate near the meter body; and a fastening bolt is provided on the surface of the meter body, wherein the fastening bolt is threadedly engaged with the threaded hole.

[0010] Both sides of the watch body are integrally provided with mounting ears, and screw holes are provided through the surface of the mounting ears.

[0011] The display screen is a segment LCD display screen.

[0012] The embedded mounting plate is made of 304 stainless steel with a thickness of 1.5-2mm, and the length of the embedded mounting plate is consistent with the height of the watch body.

[0013] The surface of the anti-fouling cover is provided with anti-slip texture.

[0014] The inner edge of the anti-fouling cover is covered with a 2-3mm thick sponge sealing ring, which fits tightly against the front of the watch body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model retains the traditional wall-mounted installation unit, which can be directly adapted to the wall installation needs of most family kitchens without changing the user's existing installation habits; at the same time, by adding an embedded installation unit, the meter body can be embedded in the kitchen cabinet or the wall reserved groove, which is compatible with the "embedded" and "integrated" kitchen decoration style, solving the problem that traditional wall-mounted gas meters cannot be adapted to special decoration scenarios and occupy a lot of space, improving installation flexibility and scenario adaptability. Moreover, when embedded, the meter body is completely embedded in the cabinet or wall groove, without protruding from the external space, avoiding damage to the overall coordination of the kitchen decoration, which meets the needs of modern families for the aesthetics of the kitchen; at the same time, embedded installation saves the space protruding from the wall of the meter body, providing more usable space for kitchen operations, especially suitable for small kitchens, improving space utilization. When wall-mounted, only the installation ear plate needs to be fixed by expansion screws, which is simple to operate; when embedded, the embedded assembly plate can be installed and fixed by tightening bolts, and the disassembly process is simple and will not cause serious damage to the wall or cabinet, reducing maintenance costs and operation difficulty.

[0016] (2) In this utility model, the anti-fouling cover is made of transparent PC material. When closed, it can completely cover the display screen and form a sealing structure through the sponge sealing ring. It can effectively prevent oil fumes and oil stains in the kitchen environment from adhering to the surface of the display screen, ensuring that the display screen remains clean for a long time and avoiding the problem of reading difficulties caused by oil stains. At the same time, the anti-fouling cover can be opened and closed. Users only need to clean the outer surface of the anti-fouling cover periodically without directly contacting the display screen, which reduces the difficulty of cleaning the display screen. Secondly, the anti-fouling cover avoids problems such as scratches, coating peeling, and circuit moisture caused by improper cleaning methods by users. It also prevents oil fumes and oil stains from entering the display screen and causing circuit damage, extending the service life of the display screen and reducing the maintenance and replacement cost of the gas meter. In addition, the anti-fouling cover is made of transparent PC material with high light transmittance. Users can clearly read the metering information on the display screen without opening the anti-fouling cover, which takes into account both anti-fouling protection and reading convenience, and improves the user experience.
