[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] Example: Figures 1-2 As shown, Figure 1 This is a front view of the gas meter in the open state according to an embodiment of the present utility model; Figure 2 This is a schematic diagram of the battery cover opening state of the gas meter according to an embodiment of the present invention.

[0041] One type of easy-to-open gas meter battery cover structure includes a battery assembly 1 and a battery cover 2. The battery assembly 1 is provided with an assembly part 3, and the battery cover 2 is rotatably assembled on the battery assembly 1 for opening and closing the assembly part 3. The assembly part 3 has a receiving cavity 30 for accommodating the battery, and the assembly part 3 and the battery cover 2 are locked together by a locking device 4. The locking device 4 includes a latching assembly 40 and a latching plate 9. The latching plate 9 is assembled on the battery cover 2, and the latching assembly 40 is fixed on the assembly part 3. The battery cover 2 and the assembly part 3 are detachably connected through the cooperation of the latching plate 9 and the latching assembly 40.

[0042] In this embodiment, when the battery cover 2 is closed, a one-button opening mechanism is adopted: the battery cover 2 is designed with a one-button opening switch. The user only needs to press the position of the corresponding latch plate 9 of the battery cover 2 gently, and the latch plate 9 and the latch assembly 40 will open or close, so that the battery cover 2 can be automatically popped open without the need to use any tools or force to open it. The operation is simple and quick.

[0043] The assembly part 3 is provided with an annular sealing groove 31, and a sealing ring 32 is installed in the annular sealing groove 31. Correspondingly, the battery cover 2 is provided with ribs 24 in the circumferential direction. When the battery cover 2 is assembled on the assembly part 3, the ribs 24 on the battery cover 2 abut against and squeeze the sealing ring 32.

[0044] In this embodiment, when the battery cover 2 is closed, the protruding rib 24 on the battery cover 2 extends into the annular sealing groove 31 on the assembly part 3, so that the protruding rib 24 squeezes the sealing ring 32; the sealing ring 32 can produce greater deformation, thereby improving the sealing effect of the sealing ring 32 in the annular sealing groove 31; and the annular sealing groove 31 and its corresponding sealing ring 32 are both annular, while the receiving cavity 30 for installing the battery is located in the annular sealing groove 31, and the sealing ring 32 is made of rubber; so when the battery cover 2 is closed, the battery box and the battery installed in it can be located in the annular sealing groove 31 structure, providing all-round sealing for the battery box and the battery. The battery receiving structure of this solution has good sealing performance, simple structure, and high practicality.

[0045] like Figure 3As shown, an assembly groove 5 is formed between the annular sealing groove 31 and the battery assembly 1, and the locking assembly 40 is built into the assembly groove 5. The design is ingenious and makes reasonable use of the structural space of the gas meter. The annular sealing groove 31 is located at the upper end of the assembly part 3, and the assembly groove 5 is also located at the upper end of the assembly part 3, and is engaged between the annular sealing groove 31 and the battery assembly 1. This improves the installation stability and safety of the locking assembly 40, and at the same time, it ensures that the assembly between the battery cover 2 and the assembly part 3 is not interfered with by other components.

[0046] like Figures 4-5 As shown, a positioning plate 20 is fixedly provided on the side of the battery cover 2 near the assembly part 3. A groove 21 is formed on the positioning plate 20. The locking plate 9 fits into the groove 21 of the positioning plate 20. The top of the locking plate 9 is on the same horizontal plane as the top of the positioning plate 20. Locking blocks 90 are formed on both sides of the top of the locking plate 9. The inner diameter of the groove 21 is consistent with the outer diameter of the assembly groove 5. In this way, when the battery cover 2 is assembled with the assembly part 3, the groove 21 on the positioning plate 20 is engaged with the assembly groove 5. At the same time, the locking plate 9 and the locking assembly 40 are engaged and locked together.

[0047] like Figures 10-11 As shown, the latch assembly 40 includes a latch housing 41, a latch pressing block 42, a lock seat 43, a return spring 44, and two latches 45. The latch pressing block 42 is fixed on the lock seat 43, and the two latches 45 are fixed on the top of the lock seat 43 and assembled on both sides of the latch pressing block 42. The latch pressing block 42, the lock seat 43, and the two latches 45 are built into the latch housing 41. The bottom of the lock seat 43 has a downward-facing mounting groove 46, and the return spring 44 is built into the mounting groove 46. The top of the lock seat 43 has a through hole 47, and a locking rod mechanism 6 is assembled in the through hole 47. A slot 8 adapted to the locking rod mechanism 6 is formed on one side of the latch housing 41.

[0048] The end of the latch plate 9 is pressed downward, and the end of the latch plate 9 extends between the two latches 45 and abuts against the latch pressing block 42. Under the compression of the return spring 44, the lock seat 43 and the locking rod mechanism 6 are driven to move downward. The guide locking pin 63 on the locking rod mechanism 6 switches between the locking groove 80 and the unlocking groove 81, thereby opening or locking the battery cover 2 and the assembly part 3.

[0049] like Figure 14 As shown, the locking rod mechanism 6 includes a locking shaft 60, a connecting locking rod 61, a limiting locking pin 62, and a guide locking pin 63; the locking shaft 60 is assembled in the through hole 47 and the rotation stroke is limited by the limiting mechanism 7; the connecting locking rod 61 is vertically fixed to one side of the locking shaft 60, the limiting locking pin 62 is fixed to the outside of the connecting locking rod 61 and corresponds to the position of the locking shaft 60, and the guide locking pin 63 is fixed to the outside of the bottom of the connecting locking rod 61 and is built into the slot 8.

[0050] like Figures 7-8 As shown, the slot 8 includes a locking slot 80 and an unlocking slot 81. The locking slot 80 and the unlocking slot 81 have a V-shaped structure. When the guide lock pin 63 is located in the locking slot 80, the battery cover 2 and the assembly part 3 are in a closed state. When the guide lock pin 63 is located in the unlocking slot 81, the battery cover 2 and the assembly part 3 are in an open state.

[0051] like Figure 13 As shown, a guide block 13 for guiding the movement of the locking pin 62 is fixed inside the locking housing 41. The guide block 13 fits against the connection between the locking groove 80 and the unlocking groove 81. When the locking pressing block 42 is pressed down through the end of the locking plate 9, the guide pin 63 on the locking rod mechanism 6 moves down along the guide block 13, so that the guide pin 63 switches between the locking groove 80 and the unlocking groove 81, thereby improving the stability and safety of opening or locking the battery cover 2 and the assembly part 3.

[0052] like Figure 12 As shown, the latch 45 includes an elastic part 451, a connecting part 452, and a locking part 453; the elastic part 451, the connecting part 452, and the locking part 453 are fixedly connected and integrally formed; this improves the structural strength and overall robustness of the latch 45, further ensuring safety in use.

[0053] Furthermore, the elastic part 451 has a U-shaped structure and is fixed to the end of the lock seat 43. This allows the elastic part 451 to have a certain deformation and recovery force, which can compress when the latch 45 locks the latch plate 9 and restore when the latch 45 separates from the latch plate 9. The locking part 453 of the elastic part has a conical structure, including a guide surface 453-1 and a locking surface 453-2. The angle between the guide surface 453-1 and the locking surface 453-2 is 60° to 80°. In this embodiment, the angle between the guide surface 453-1 and the locking surface 453-2 is 70°.

[0054] When the battery cover 2 is closed, the locking block 90 on the locking plate 9 contacts the guide surface 453-1. When the operator presses the battery cover 2, the locking block 90 enters between the two locking surfaces 453-2. At the same time, the locking buckle 45 enters into the locking box 41 under the compression of the return spring 44. Through the locking rod mechanism 6, the guide locking pin 63 on the locking rod mechanism 6 moves from the unlocking groove 81 to the locking groove 80. The locking block 90 is locked between the two locking surfaces 453-2, so that the battery cover 2 and the assembly part 3 are connected to each other.

[0055] When it is necessary to separate the battery cover 2 from the assembly part 3, press the battery cover 2 to move the latch plate 9 downward, which in turn drives the locking rod mechanism 6 to move. The guide locking pin 63 on the locking rod mechanism 6 moves from the locking groove 80 to the unlocking groove 81. The latch 45 moves out of the latch box 41 under the reset of the return spring 44, and the two latches 45 separate, so that the latch block 90 moves out from the two latches 45, and the battery cover 2 separates from the assembly part 3.

[0056] like Figure 9 As shown, Figure 9 This is a schematic diagram of the locking state of the latch assembly in an embodiment of the present utility model; a guide block 49 is fixedly provided on the side of the lock seat 43 away from the slot 8; correspondingly, a guide groove 48 is formed on the lock housing 41 along its height direction; by setting the guide block 49 to move up and down in the guide groove 48, the movement of the lock seat 43 in the lock housing 41 is more stable and efficient, thus improving the safety of use.

[0057] like Figure 12 and Figure 14 As shown, the limiting mechanism 7 includes a limiting part 70 in a stepped state. The limiting part 70 is fixed on the lock seat 43 and located at the top of the through hole 47. A guide limiting surface 64 adapted to the limiting part 70 is formed on the lock shaft 60. The limiting part 70 abuts against the guide limiting surface 64. When the latch pressing block 42 presses down through the end of the latch plate 9, the limiting part 70 abuts against the guide limiting surface 64. As the pressing gradually deepens, the end of the limiting part 70 and the guide limiting surface 64 will be displaced, thereby causing the limiting locking pin 62 and the guide locking pin 63 on the locking rod mechanism 6 to move in linkage. The guide locking pin 63 switches more smoothly between the locking groove 80 and the unlocking groove 81, making it more convenient to lock or separate the battery cover 2 from the assembly part 3.

[0058] like Figure 2 As shown, the battery assembly 1 is fixedly connected to two spaced-apart connecting brackets 10. A positioning groove 11 is formed in the middle of each connecting bracket 10, and a torsion spring 12 is installed within the positioning groove 11. A connecting block 22, adapted to the connecting brackets 10, is fixedly connected to the lower part of the battery cover 2. A positioning post 23 is installed on the connecting block 22, passing through the connecting block 22, the connecting brackets 10, and the torsion spring 12 in sequence; this is used to assemble the battery cover 2 onto the battery assembly 1. This design allows the battery cover 2 to be rotatably connected to the battery assembly 1, improving assembly efficiency. Simultaneously, the torsion spring 12 facilitates the opening of the battery cover 2, resulting in a simple structure and easy operation.

[0059] like Figure 6As shown, the surface of the battery cover 2 is provided with an opening indicator 14 and anti-slip protrusions 15; the opening indicator 14 and anti-slip protrusions 15 are integrally formed with the battery cover 2; this improves the structural strength and overall firmness of the entire battery cover 2, further ensuring safety in use; moreover, the anti-slip protrusions 15 increase the friction when the user presses, preventing slippage; at the same time, a clear opening indicator 14 is provided on the battery cover or gas meter housing to guide the user to operate correctly.
