Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: an NB-IoT Internet of Things gas meter capable of remote upgrade, including a gas meter 1 for detecting the gas usage of users and a mounting bracket 2 for fixing the gas meter 1. The mounting bracket 2 is inserted into the front end of the gas meter 1. A positioning block 6 for positioning the gas meter 1 is fixedly connected to the front end of the mounting bracket 2. A positioning groove 7 for accommodating the gas meter 1 is provided at the rear end of the gas meter 1. The positioning block 6 and the positioning groove 7 are adapted to each other. When installing the gas meter 1, it is necessary to align the positioning groove 7 with the positioning block 6 and then insert the gas meter 1 into the front end of the mounting bracket 2. A connection assembly 4 for fixing the gas meter 1 is provided at the left end of the mounting bracket 2. The connection assembly 4 includes a T-shaped rod 45 for driving the connection block 42 to move. The T-shaped rod 45 penetrates and is slidably connected to the left end of the mounting bracket 2. A fixing assembly 5 for fixing the pressing block 46 is provided at the front end of the T-shaped rod 45. An installation plate 3 for installing bolts is fixedly connected to the left end of the mounting bracket 2. The mounting bracket 2 can be fixed to the installation point by using bolts to fix the installation plate 3 at the installation point.

[0032] Refer to Figure 2 - Figure 4 , the connection assembly 4 further includes a connection block 42 for fixing the gas meter 1. The left end of the connection block 42 is fixedly connected to the right end of the T-shaped rod 45. When the T-shaped rod 45 moves left and right, it will drive the connection block 42 to move left and right synchronously. A connection groove 41 for accommodating the connection block 42 is provided at the left end of the gas meter 1. The connection block 42 and the connection groove 41 are adapted to each other. When the connection block 42 is inserted into the inside of the connection groove 41, the gas meter 1 will be fixed to the right end of the mounting bracket 2. The connection block 42 is set as a trapezoid, and the trapezoidal inclined surface of the connection block 42 faces forward. When the inclined surface of the connection block 42 is squeezed, the connection block 42 will be forced to move outwards. A sliding sleeve 44 for accommodating the sliding shaft 43 is fixedly connected to the left end of the mounting bracket 2. A sliding shaft 43 for driving the connection block 42 to move is slidably connected to the right end of the sliding sleeve 44. The right end of the sliding shaft 43 is fixedly connected to the left end of the connection block 42. When the sliding shaft 43 moves, the connection block 42 will be driven to move synchronously. A connection spring 48 for pulling the sliding shaft 43 is fixedly connected to the left end of the sliding shaft 43. The left end of the connection spring 48 is fixedly connected to the inner wall of the sliding sleeve 44. The connection spring 48 will always pull the connection block 42 to the left. A pressing block 46 for driving the T-shaped rod 45 to move is rotatably connected to the left end of the T-shaped rod 45. The distance from the rotation axis of the pressing block 46 to the top is greater than the distance from its rotation axis to the right end. Therefore, by rotating the pressing block 46 upwards, the T-shaped rod 45 can be driven to move leftwards. A handle 47 for facilitating the operator to rotate the pressing block 46 is fixedly connected to the bottom end of the pressing block 46.

[0033] Refer to Figure 1 - Figure 3The fixing assembly 5 includes a fixing block 51 for fixing the pressing block 46. The fixing block 51 is slidably connected to the front end of the T-shaped rod 45. The fixing block 51 is set in an L shape. By toggling the front end of the fixing block 51, the fixing block 51 can be driven to move up and down. The front end of the pressing block 46 is provided with a fixing groove 53 for accommodating the fixing block 51. The front end of the pressing block 46 is provided with an unlocking groove 54 for accommodating the fixing block 51 near the left end. The fixing block 51 is adapted to the fixing groove 53. When the fixing block 51 is inserted into the fixing groove 53, the fixing block 51 is unlocked. After being inserted into the fixed groove 53, the right end of the pressing block 46 will be parallel to the left end of the mounting frame 2, and the fixing block 51 and the unlocking groove 54 will be adapted. When the fixing block 51 is inserted into the unlocking groove 54, the top of the fixing block 51 will be parallel to the left end of the mounting frame 2, and the bottom end of the fixing block 51 is fixedly connected with a fixing spring 52 for pushing the fixing block 51, and the bottom end of the fixing spring 52 is fixedly connected to the inner wall of the T-bar 45, and the fixing spring 52 will always push the fixing block 51 upward.

[0034] Working principle: when the gas meter 1 needs to be removed for maintenance, the fixing block 51 needs to be pushed downward first to disengage it from the inside of the fixing groove 53, and then the handle 47 can be rotated to drive the pressing block 46 to rotate. The rotation of the pressing block 46 will drive the T-bar 45 to move to the left, and the movement of the pressing block 46 to the left will drive the connecting block 42 to the left and disengage from the inside of the connecting groove 41. When the unlocking groove 54 is aligned with the fixing block 51, the fixing block 51 can be released. At this time, the fixing block 51 will be pushed by the fixing spring 52 to fit into the inside of the unlocking groove 54 to fix the pressing block 46, and then the gas meter 1 can be pulled forward to be taken out.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
