[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: an adaptive clamp device for a gas meter shell, including a base 1, which can support the entire device and is closed inside. A clamping block 2 is slidably arranged on the top of the base 1. The clamping block 2 can slide horizontally to clamp shells of different sizes, and the upper end of the clamping block 2 is an inclined surface that can be squeezed to slide toward both ends to facilitate the sliding of the shell. The lower part of the clamping block 2 is slidably connected with a sliding block 8. The sliding block 8 is L-shaped and can be squeezed by air pressure to drive the clamping block 2 to slide. The outer part of the sliding block 8 is slidably connected to the middle inner part of the base 1. The base 1 limits the sliding block 8 to slide horizontally and linearly within a fixed distance. The front part of the base 1 is fixedly connected with a fixed block 6. The front side of the fixed block 6 A block is fixed at the end to block and limit the sliding of piston 4 within a fixed distance, so that when the shell with an irregular shape on the side end slides in, it can slide to both ends to facilitate the sliding of the shell to achieve an adaptive effect. The internal sliding connection of the fixed block 6 is connected with a slider 9, and the slider 9 can limit the inclined plane block 7 to slide relatively straight. The interior of the slider 9 is elastically connected to the inclined plane block 7 through a spring 10, which can fix the piston 4 so that it no longer slides and keeps the shell clamped and fixed. One end of the spring 10 is fixedly connected to the inside of the slider 9, and the other end of the spring 10 is fixedly connected to the outside of the left end of the inclined plane block 7. The spring 10 squeezes to keep the inclined plane block 7 fixed inside the side end of the piston 4.

[0032] Reference Figure 1-Figure 3 The upper part of the inclined surface block 7 is fixedly connected with a square rod 11, and the square rod 11 can drive the inclined surface block 7 to slide out of the piston 4 to release the limit so that it can slide. The outer part of the square rod 11 is slidably connected to the top inner part of the slider 9 and the upper inner part of the fixed block 6. The square rod 11 can slide with the cylinder 12 to adjust the position of the slider 9, so that the piston 4 can slide in different length ranges so that the sliding range of the clamping block 2 can be adjusted. The outer part of the square rod 11 is slidably connected with the cylinder 12, and the lower part of the cylinder 12 is slidably connected to the fixed block 6. Inside, the cylinder 12 can fix the position of the slider 9 so that it is fixed relative to the fixed block 6. The square rod 11 can slide horizontally and vertically by sliding up the cylinder 12. The right end of the inclined block 7 is slidably connected to the outside with a piston 4. The sliding of the piston 4 can drive the clamping block 2 to slide inside the base 1 to clamp shells of different sizes and shells with different curved surfaces. The rear part of the piston 4 is slidably connected to the inside of the front end of the base 1. The base 1 limits the piston 4 to slide horizontally and linearly within a fixed distance. The rear part of the base 1 is slidably connected to an adjustment component.

[0033] Reference Figure 1 , Figure 2 and Figure 4The adjusting component includes a piston plate 5. The sliding of the piston plate 5 can adjust the internal air pressure of the base 1 to change the size of the force of the clamping shell. The outside of the piston plate 5 and the outside of the rotating column 3 are both slidably connected to the rear end of the base 1. The base 1 limits the piston plate 5 and the rotating column 3 to slide linearly within a fixed distance. The internal rotation of the piston plate 5 is connected to the rotating column 3. The rotating column 3 can drive the piston plate 5 to slide and adjust the air pressure, and a square groove is opened at the side end to be clamped with the arc block 14 so that the position of the rotating column 3 is fixed. The two ends of the rotating column 3 are internally slidably connected. There is an arc block 14, which can be squeezed by the square groove to slide out of the rotating column 3 to release the limit. The side of the arc block 14 is elastically connected to the rear inner wall of the base 1 through the spring 2 13. The side end of the arc block 14 is an arc surface and can slide out of the rotating column 3 under compression, making it more convenient to adjust the clamping force. One end of the spring 2 13 is fixedly connected to the rear end of the base 1. The spring 2 13 squeezes the arc block 14 to keep it fixed inside the rotating column 3, and the other end of the spring 2 13 is fixedly connected to the outside of the side end of the arc block 14.

[0034] Working principle: by sliding up, the cylinder 12 slides out of the upper end of the fixed block 6, and then the cylinder 12 is slid horizontally, so that the cylinder 12 drives the square rod 11 to slide horizontally inside the fixed block 6 and the slider 9, and the square rod 11 drives the inclined block 7 to slide horizontally out of the piston 4, and the piston 4 slides backward until it contacts the square block, and then slides into the shell in the middle of the clamping block 2. At this time, the upper inclined surface of the clamping block 2 is squeezed and can slide to both ends. When the shell slides in completely, the piston 4 is squeezed to slide into the base 1, until the inclined block 7 can slide into the side end of the piston 4 under the pressure of the spring 10 to fix it, and then the cylinder 12 is slid up and then the cylinder 12 is slid back and forth to drive the square rod 11 to slide, and the square rod 1 1 can drive the inclined block 7 and the slider 9 to slide inside the fixed block 6, so that the size of the clamping force and the sliding range of the piston 1 4 can be adjusted, so that it can adapt to different clamping force requirements. When the clamping force size does not meet the requirements, the rotating column 3 can be rotated to make the rotating column 3 squeeze the arc blocks 14 at both ends to slide into the base 1 to squeeze the spring 2 13 inside, and then the rotating column 3 is slid horizontally and linearly to drive the piston plate 5 to slide and squeeze to adjust the internal air pressure of the base 1 so that the clamping force range can be changed, thereby increasing the use range and practicality of the overall device, and then the rotating column 3 is rotated back to its original position. At this time, the arc blocks 14 at both ends are squeezed by the spring 2 13 to slide into the side ends of the rotating column 3 so that they no longer slide.

[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.
