The connecting plate 601 is movably installed at the lower position of the back of the meter body 1, the connecting groove 607 is opened on the connecting plate 601, and the sliding rod 613 is fixedly connected to the hanging plate 602. The lower position of the connecting groove 607 is provided on the side walls on both sides of the connecting groove 607, and the sliding rod 613 is movably installed in the sliding groove 608. The fixing component 6 also includes a connecting rod 604 and a connecting hole 605. The connecting hole 605 is provided on the connecting plate 601. The connecting rod 604 is fixedly connected to the back position of the meter body 1. The connecting plate 601 is movably installed with the connecting rod 604 through the connecting hole 605. The connecting plate 601 is convenient for rotating backward on the connecting rod 604 through the connecting hole 605. With the rotation of the connecting plate 601, the lateral distance between the wall and the meter body 1 changes. By rotating the connecting plate 601, the distance between the meter body 1 and the wall is adjusted, so that the meter body 1 is more suitable for installation close to the wall.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the fixing plate 603 is fixedly connected to the upper position of the back side of the meter body 1, the pressing plate 612 is movably installed with the connecting plate 601, the hanging hole 615 is provided on the hanging plate 602, the fixing component 6 also includes a fixing groove 606 and an inserting plate 616, the fixing groove 606 is provided on the fixing plate 603, the inserting plate 616 is fixedly connected to the upper position of the hanging plate 602, the inserting plate 616 is movably installed in the fixing groove 606 of the fixing plate 603, the fixing component 6 also includes an installation groove 609, the installation groove 609 is provided on both sides of the connecting plate 601, and is located at the side position of the slide groove 608, the fixing component 6 also includes a bottom plate 610 and a spring 611, the bottom plate 610 is fixedly connected to the bottom wall of the installation groove 609, the spring 611 and the pressing plate 612 are movably installed in the installation groove 609, the spring 611 is located between the bottom plate 610 and the pressing plate 612, and the two ends of the spring 611 are respectively connected to the bottom plate 610 and the pressing plate 612. The plate 610 and the pressure plate 612 are fixedly connected, and the fixing assembly 6 also includes a pressure rod 614, which is fixedly connected to the two sides of the hanging plate 602. The pressure rod 614 is movably installed in the installation groove 609 and is located above the pressure plate 612. The pressure rod 614 is inserted into the installation groove 609 to compress the pressure plate 612, so that the pressure plate 612 moves downward to compress the spring 611, and the slide bar 613 moves movably in the slide groove 608, so that the hanging plate 602 is close to the connecting plate 601, and then the connecting plate 601 and the hanging plate 602 are rotated upward. When the hanging plate 602 is rotated to the lower position of the fixed plate 603, the hanging plate 602 is released, the compressed spring 611 is reset, the pressure plate 612 and the pressure rod 614 are pushed upward, and the plug plate 616 is inserted into the installation groove 609. The pressure rod 614 moves upward, but does not move out of the installation groove 609, so that the connecting plate 601 and the hanging plate 602 are easy to store.

[0024] It should be noted that the utility model is a gas meter that is easy to fix. When the meter body 1 is installed, observe the distance between the meter body 1 and the wall. After drilling holes in the wall, install the wall-mounted screws, and then rotate the connecting plate 601 backward. The connecting plate 601 rotates on the connecting rod 604 through the connecting hole 605. When the connecting plate 601 is rotated to a suitable position, pull the hanging plate 602 upward to make the sliding rod 613 move upward in the sliding groove 608, and the pressing rod 614 moves out of the installation groove 609. Then rotate the hanging plate 602 upward to keep the hanging plate 602 vertical, and install the hanging hole 615 with the screws on the wall. Then, the air inlet 2 and the air outlet 3 on the meter body 1 are connected to the gas pipeline. The gas meter load is mainly composed of the fixing component 6, the connecting port of the air inlet 2 and the gas pipeline, and the connecting port of the air outlet 3 and the gas pipeline. Through the fixing component 6, the wall can provide support for the meter body 1, thereby avoiding the air inlet 2 and the connecting port of the gas pipeline, the air outlet 3 and the gas pipeline connection port is too heavy, causing the connection port to loosen and gas to fall off. There is no supporting structure under the gas meter, such as the gas meter is not installed to the gas cabinet. When the gas meter is close to the wall, the fixing component 6 can be used to provide support for the gas meter, so that the installation of the gas meter is more fixed. When the fixing component 6 is not used, the hanging plate 602 is rotated, and when the hanging plate 602 and the connecting plate 601 are in the same plane, the pressure rod 614 of the hanging plate 602 is inserted into the installation groove 60 9, the pressing plate 612 is squeezed, and the pressing plate 612 moves downward to compress the spring 611, and then the connecting plate 601 and the hanging plate 602 are rotated upward to the lower position of the fixed plate 603, the hanging plate 602 is loosened upward, and the compressed spring 611 restores the open part, and the plug plate 616 is inserted into the installation groove 609 of the fixed plate 603, so that the hanging plate 602 and the connecting plate 601 are stored in the lower position of the fixed plate 603, making it easy to store the hanging plate 602 and the connecting plate 601.
