Description

Technical Field

[0001] This utility model relates to the field of gas meter housings, and in particular to an Internet of Things (IoT) gas meter housing. Background Technology

[0002] To meet the intelligent operation requirements of IoT gas meters, their casings need to balance the ease of battery replacement with environmental adaptability. Currently, the opening methods of the battery covers of IoT gas meters generally suffer from poor operational convenience, low structural reliability, and short service life, making them unsuitable for scenarios requiring frequent battery replacements.

[0003] Currently, the mainstream opening methods are mainly snap-on or threaded. Snap-on structures require manually prying open the clips on the edge of the battery cover, which not only causes finger pain but also makes it inconvenient and difficult to open due to the gas meter being located in a narrow corner. Threaded structures require tools such as screwdrivers for disassembly; if the threaded surfaces become stuck due to rust or wear after long-term use, it will also make opening the cover difficult. Based on this, we designed an IoT gas meter casing to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an Internet of Things (IoT) gas meter housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an IoT gas meter housing, comprising a housing and a meter cover assembly mounted on the outer wall of the housing, wherein the meter cover assembly comprises an opening mechanism, a battery compartment, a battery cover, and a viewing window cover;

[0006] The opening mechanism includes a linkage group, which consists of two linkages. A pressing element is inserted in the middle of the linkage group. Fixed blocks are fixedly connected to both ends of the linkage group. A spring is fixedly connected to the side of the fixed block away from the linkage group.

[0007] When the battery cover is closed, the battery cover pushes the fixing block to compress the spring to the preset position, and then the spring's compression force fixes it. When the battery cover is opened, pressing the pressing part drives the linkage assembly to move to both sides, compressing the spring again, so that the battery cover opens quickly.

[0008] Preferably, the ends of the two connecting rods near the pressing member in the connecting rod assembly are both set as inclined surfaces, the insertion end of the pressing member is set as a trapezoidal surface, and the trapezoidal surface of the pressing member is inserted into the middle of the inclined ends of the two connecting rods.

[0009] Preferably, the outer wall of the viewing window cover is fixedly connected to the watch case, the side of the watch case away from the viewing window cover is fixedly connected to the machine housing, and the opening mechanism is disposed inside the watch case.

[0010] Preferably, the end of the spring away from the fixed block is fixedly connected to the inner wall of the watch case, and two sliding grooves are formed on the inner wall of the watch case near the pressing member. Slider blocks are fixedly connected to both sides of the pressing member, and the sliders are slidably connected to the inner wall of the sliding grooves.

[0011] Preferably, the outer wall of the watch case has a groove located below the window cover, the battery compartment is fixedly connected to the inner wall of the groove, the bottom of the watch case has a shaft hole, the inner wall of the shaft hole is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is rotatably connected to a connector, and the lower part of the connector is rotatably connected to the battery cover.

[0012] Preferably, a waterproof groove is provided around the battery compartment, a soft rubber ring is fixedly connected to the inner wall of the waterproof groove, a protrusion is fixedly connected to the top of the battery cover, buckles are fixedly connected to both ends of the battery cover, and a pressing port is provided at the end of the battery cover away from the connector.

[0013] Preferably, the top of the housing has two fixedly connected interfaces, and the top of each interface is fixedly fitted with a sealing cap.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model effectively solves the problems of difficult operation and low reliability of existing mechanisms by optimizing the opening mechanism structure. It employs a linkage group consisting of two connecting rods in conjunction with a trapezoidal pressing component. When pressed, the inclined surface of the connecting rod drives the fixed block to move, thereby opening the battery cover. Furthermore, the guide and limiting design of the sliding groove inside the case and the slider of the pressing component, as well as the stable connection between the spring and the fixed block, effectively prevent the connecting rod from jamming, shifting, or parts from falling off, extending the service life of the mechanism and reducing maintenance costs.

[0016] 2. Regarding moisture protection, this utility model specifically addresses the sealing defects of existing casings, significantly improving environmental adaptability. The waterproof groove around the battery compartment, together with the soft rubber ring and the protrusion on the battery cover, forms a multi-layer sealing structure that effectively prevents moisture or water droplets from seeping into the battery compartment, avoiding corrosion of the battery electrodes, leakage, and damage to internal electronic components, further ensuring the overall durability of the casing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-4 The illustrated IoT gas meter housing includes a housing 1 and a cover assembly 2 mounted on the outer wall of the housing 1. The cover assembly 2 includes an opening mechanism 21, a battery compartment 22, a battery cover 23, and a viewing window cover 24. The outer wall of the viewing window cover 24 is fixedly connected to the housing 25. The side of the housing 25 away from the viewing window cover 24 is fixedly connected to the housing 1. The opening mechanism 21 is disposed inside the housing 25 and includes a linkage group 211, which consists of two linkages. A pressing member 212 is inserted in the middle of the linkage group 211. Two sliding grooves are formed on the inner wall of the housing 25 near the pressing member 212. Sliding blocks 215 are fixedly connected to both sides of the pressing member 212 and are slidably connected to the inner wall of the sliding grooves. The two linkages in the linkage group 211... The end near the pressing member 212 is set as a bevel, and the insertion end of the pressing member 212 is set as a trapezoidal surface. The trapezoidal surface of the pressing member 212 is inserted into the middle of the bevel ends of the two connecting rods. The two ends of the connecting rod assembly 211 are fixedly connected to the fixing blocks 213. The side of the fixing block 213 away from the connecting rod assembly 211 is fixedly connected to the spring 214. The end of the spring 214 away from the fixing block 213 is fixedly connected to the inner wall of the watch case 25. When the battery cover 23 is closed, the battery cover 23 pushes the fixing block 213 to squeeze the spring 214 to the preset position, and then the compression force of the spring 214 fixes it. When the battery cover 23 is opened, pressing the pressing member 212 drives the connecting rod assembly 211 to move to both sides, compressing the spring 214 again, so that the battery cover 23 opens quickly.

[0026] like Figures 5-6 As shown, as a technical optimization of this utility model, the outer wall of the watch case 25 is provided with a groove, which is located below the window cover 24. The battery compartment 22 is fixedly connected to the inner wall of the groove. The bottom of the watch case 25 is provided with a shaft hole, and a rotating shaft 251 is fixedly connected to the inner wall of the shaft hole. A connector 252 is rotatably connected to the outer wall of the rotating shaft 251. The lower part of the connector 252 is rotatably connected to the battery cover 23. A waterproof groove 253 is provided around the battery compartment 22. A soft rubber ring 254 is fixedly connected to the inner wall of the waterproof groove 253. A protrusion 231 is fixedly connected to the top of the battery cover 23. Buckles 232 are fixedly connected to both ends of the battery cover 23. A pressing port 233 is provided at the end of the battery cover 23 away from the connector 252. Two interfaces 3 are fixedly connected to the top of the casing 1. A sealing cover 4 is fixedly fitted to the top of the interface 3 to effectively prevent moisture or water droplets from seeping into the battery compartment 22, avoid corrosion of the battery terminals, leakage and damage to internal electronic components, and further ensure the overall durability of the casing.

[0027] When the battery of the IoT gas meter needs to be replaced, first press the pressing part 212 of the cover opening mechanism 21 vertically. The trapezoidal surface of the pressing part 212 fits and drives the inclined surfaces of the two connecting rods of the connecting rod assembly 211, pushing the connecting rods to move to both sides, causing the fixing block 213 to compress the spring 214. After pressing to the preset stroke, the locking of the fixing block 213 to the buckle 232 of the battery cover 23 is released, so the battery cover 23 flips open around the bottom pivot 251 to expose the battery compartment 22. After replacing the new battery, flip the battery cover 23 upward around the pivot 251. The buckle 232 pushes the fixing block 213 to compress the spring 214. After the battery cover 23 is completely closed and the buckle 232 is engaged, the fixing block 213 presses against the buckle 232 under the return force of the spring 214 to achieve locking. The waterproof groove 253 and the soft rubber ring 254 simultaneously complete the sealing with the protrusion 231.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
