[0002] A water meter is an instrument that measures water flow. It measures the cumulative flow of water and is generally divided into two categories: volumetric water meters and velocity water meters. When selecting a water meter, you should first estimate the size and range of the flow rate normally used, and then select a water meter with a specification that is closest to the commonly used flow rate.

[0003] In rural areas, water meters are usually installed outdoors. On snowy days, water meters are prone to freezing in low temperature environments, causing them to fail to work properly. In addition, the water meter contains water. When the ambient temperature is too low, the water will freeze and expand, which can easily damage the internal structure of the water meter and even cause it to rupture. Summary of the invention

[0004] The utility model aims to provide a freeze-resistant water meter with freeze-resistant performance to avoid damage caused by freezing in a low-temperature environment.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: provide an antifreeze water meter, including a water meter body, the outer wall of the water meter body is fixedly connected with a guide tube, and the number of the guide tubes is multiple, the bottom of the water meter body is fixedly connected with a base, the top of the inner wall of the base is provided with a slide groove, and the number of the slide grooves is two, the inner walls on both sides of the two slide grooves are provided with limited grooves, the inner walls of the two slide grooves are fixedly connected with sliding springs, and the number of the sliding springs is two, the other ends of the two sliding springs are fixedly connected with sliders, the outer walls on both sides of the sliders are fixedly connected with limited blocks, the limit blocks are located inside the limit grooves, the bottoms of the two sliders are movably connected with linkage rods, and the number of the linkage rods is two, the inner wall of the base is fixedly connected with a moving rod, the outer walls of the moving rod are both sleeved with moving blocks, the top of the moving block is movably connected to the bottom of the other end of the linkage rod, the bottoms of the two moving blocks are fixedly connected with a heat preservation cover, and the inner wall of the heat preservation cover is fixedly connected with a heat preservation layer.

[0006] Optionally, a slot is provided on the outer wall of the heat preservation cover on the left side, a locking plate is arranged inside the slot, a pull plate is fixedly connected to the top of the locking plate, the pull plate is located outside the top end of the heat preservation cover on the left side, both ends of the bottom of the pull plate are fixedly connected to locking springs, and the heat preservation cover on the right side and the opposite surface of the heat preservation cover on the left side are fixedly connected with an insertion plate, and a locking groove is provided inside the insertion plate.

[0007] Optionally, the two heat-insulating covers respectively wrap the water meter body inside, and the two flow guide pipes respectively penetrate the two heat-insulating layers.

[0008] Optionally, the outer wall of the moving rod is provided with a moving groove, and there are multiple moving grooves. The inner walls of the two moving blocks are fixedly connected with moving bars, and there are multiple moving bars respectively, and the multiple moving bars are respectively located inside the multiple moving grooves.

At this time, the multiple locking springs are all in a stretched state. After the two plug plates are fully entered into the two slots, the multiple locking springs rebound, so that the two locking plates are reset and enter the locking grooves opened inside the two plug plates respectively. At this time, the two heat preservation covers are locked and buckled with each other, so that the water meter body is in a closed space; the inner walls of the two heat preservation covers are provided with heat preservation layers, which keep the water meter body located inside the two heat preservation covers warm and prevent freezing.
