Description

Technical Field

[0001] This utility model relates to the field of gas meter housings, specifically a sealing component and a gas meter housing with wireless communication function. Background Technology

[0002] The gas meter casing consists of a housing, a cover plate, a fixing mechanism, and a connecting mechanism. The housing, as the core frame, first houses the meter core, metering components, and other internal parts. It also has a pre-drilled mounting slot for the cover plate and an interface for the connecting mechanism, providing a base for assembling other components. The cover plate aligns with the mounting slot on the housing and snaps shut, sealing the internal space of the housing to prevent dust and moisture intrusion, while also forming an external protective layer. The fixing mechanism then locks in place, firmly securing the cover plate to the housing to prevent loosening due to gas pressure or vibration, ensuring the overall structural stability. Finally, the connecting mechanism connects to the pre-set gas duct interface on the housing. One end connects to an external gas pipeline, and the other end connects to the internal gas duct of the housing through a sealing structure. With the housing, cover plate, and fixing mechanism forming a sealed space, gas can enter and exit the meter casing without leakage.

[0003] In the existing technology, the gas meter casing and cover plate are connected by a flange, which requires sealing treatment at the connection. With the development of the market, gaskets are installed between the casing and the cover plate to enhance the sealing effect.

[0004] However, the gasket installed between the housing and the cover plate is susceptible to temperature fluctuations when the outside temperature is high, which affects its sealing performance. Furthermore, when significant leakage occurs at the flange sealing surface, internal repairs are required. The flange connection requires the use of a screwdriver to loosen and loosen multiple bolts. Some bolts are difficult to operate due to corrosion or confined spaces, further complicating the process and resulting in low work efficiency. Therefore, a sealing component and a gas meter housing with wireless communication capabilities need to be designed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a sealing component and a gas meter housing with wireless communication function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing assembly, including a connecting plate one, a housing fixed to the bottom of the connecting plate one, a gas meter inserted inside the housing, a connecting plate two inserted to the top of the connecting plate one, a cover plate fixed to the top of the connecting plate two, a slot and an insertion hole provided on the top surface of the connecting plate one, an insertion block fixedly mounted on the bottom of the connecting plate two, a fixing rod installed inside the insertion block, two arc-shaped side plates on the fixing rod, a spring rope fixed to one end of the fixing rod, a fixing block sliding inside the fixing rod, and a rotating plate rotating on the surface of the fixing block.

[0007] Preferably, the fixing rod is folded out from the second connecting plate and inserted into the insertion hole. The fixing block is pulled to the bottom of the first connecting plate by the spring rope. The fixing block rotates on the fixing rod until the two rotating plates on both sides rotate to be perpendicular to the fixing block, which brakes the spring rope.

[0008] Preferably, the surface of the housing is provided with an observation port, and a glass plate is fixedly installed inside the observation port. The position of the observation port is consistent with the position that needs to be observed in the internal gas meter. The insertion hole passes through the connecting plate and is connected to the slot. A rubber pad is installed inside the slot, and the rubber pad is located between the insertion block and the connecting plate.

[0009] Preferably, a storage groove is provided on the bottom surface of the insert block, a rotating shaft is provided inside the storage groove, the fixing rod is sleeved on the surface of the rotating shaft, and an anti-slip pad is installed inside the storage groove, with the anti-slip pad located between the fixing rod and the connecting plate.

[0010] Preferably, the shape of the fixing rod is specifically described as follows: two arc-shaped side plates are fixed to one side of a cylindrical base, and the fixing block is fixed to one end of a spring rope and located between the two side plates of the fixing rod.

[0011] Preferably, the surface of the fixing block is provided with a groove, two sets of connecting blocks are fixed on the surface of the groove, a rotating rod is fixed between the sets of connecting blocks, the surface of the rotating plate is provided with a hole, and the rotating plate is sleeved on the surface of the rotating rod through the hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: With the addition of a fixing rod, insert, and slot, connecting plate one and connecting plate two are connected together by insert and slot and braked by the fixing rod and fixing block for sealing. This helps to protect the gasket from the influence of the external temperature when the external temperature is high. Furthermore, the gasket can be disassembled by pulling the fixing block, which reduces the amount of work required and improves work efficiency. Attached Figure Description
