[0002] The water meter case is a vessel used to cover and protect the water meter. Some water meter cases used in pipes not only need to be used to protect the water meter inside, but also need to be used to limit the connection and fix it to reduce the loosening of the water meter.

[0003] Under the existing technology, the water meter shell is usually made of copper material. Since the copper block is soft in texture, it can be made into a corresponding shape by die-casting. The blocks used for connection around the cover are also formed by die-casting. It is easier to die-cast these smaller blocks using copper material, but it is more difficult to die-cast other materials. However, the cost of copper blocks is high, and the overall production cost is high. Utility Model Content

[0004] In order to solve the problem that the existing technology uses copper material to die-cast these smaller blocks more easily, but uses other materials for die-casting but is more difficult to form, but the cost of copper blocks is high and the overall production cost is high, this application provides a stainless steel cover, and the specific solution is as follows.

[0005] A water meter case comprises a stainless steel shell, wherein the stainless steel shell is provided with a through hole, an inner wall of the stainless steel shell is provided with an internal thread, and a plurality of connecting blocks are provided on the side wall of the stainless steel shell, wherein the connecting blocks are welded to the stainless steel shell.

[0006] By adopting the above technical solution, stainless steel is used as the cover, which has lower overall cost, higher hardness and stability, and can reduce rust and damage. At the same time, a connecting block is provided for connection or limiting, and the connecting block and the stainless steel shell are connected by welding. The connecting block on the stainless steel shell is difficult to die-cast, which has high cost and is difficult to form, while welding is easier to operate and form, and has lower production costs.

[0007] Optionally, the connection blocks are arranged at equal intervals along the side wall of the stainless steel shell.

[0008] By adopting the above technical solution, the connecting blocks are arranged at equal intervals, which can just limit or connect the stainless steel shell through the connecting blocks. The connecting blocks arranged at equal intervals can be connected and supported from multiple directions, which is more convenient for supporting the stainless steel shell and can further improve the stability after installation.

[0009] Optionally, the connection blocks are each provided with a connection hole for the connection wire to pass through.

[0010] By adopting the above technical solution, a connection hole is opened on the connection block, and the connection block can be connected to the pipeline through a wire, which can further improve the stability of the stainless steel shell after installation.

[0011] Optionally, a fitting portion is provided on a side of the connecting block close to the stainless steel shell, the fitting portion is provided corresponding to the shape of the stainless steel shell, and the fitting portion abuts against the side wall of the stainless steel shell.

[0012] By adopting the above technical solution, a fitting portion is provided on the stainless steel shell, so that the connecting block and the stainless steel shell can fit more closely together, which can further improve the efficiency and effect of welding, and further improve the convenience of welding and the effect after welding.

[0013] Optionally, a limiting cylinder is further provided on the stainless steel shell, and the limiting cylinder is integrally provided with the stainless steel shell, and the diameter of the limiting cylinder is smaller than the diameter of the stainless steel shell.

[0014] By adopting the above technical solution, a limiting cylinder is provided on the stainless steel shell, and the limiting cylinder can cooperate during installation and connection, thereby further improving the convenience of installation and also improving the stability after installation.

[0015] Optionally, a limiting ring is further provided on the limiting cylinder, the limiting ring is fixedly connected to the limiting cylinder, the middle portion of the limiting ring is penetrated and communicated with the through hole, and the limiting ring is used to abut against the pipeline.

[0016] By adopting the above technical solution, a limiting ring is provided on the limiting cylinder, and the limiting ring can abut against the pipeline, which can further improve the stability after installation after the connection is completed.

[0017] Optionally, the limiting ring is provided at the end of the limiting cylinder, and the side of the limiting ring close to the limiting cylinder is welded to the stainless steel shell.

[0018] By adopting the above technical solution, the limit ring is also connected by welding. Since the limit ring is also difficult to be formed by die-casting, the use of welding can further improve the convenience of forming and reduce the forming cost.

[0019] Optionally, a welding ring groove is provided on a side of the outer wall of the limiting cylinder close to the limiting ring, and the welding ring groove is circumferentially arranged around the limiting cylinder.

[0020] By adopting the above technical solution, a welding ring groove is opened on the side of the limiting cylinder close to the limiting ring, and welding can be performed at the welding ring groove, which can further improve the convenience of welding and also improve the welding effect.

[0021] In summary, this application has at least the following beneficial effects:

[0022] 1. The present application solves the problem that the lower cover of the prior art uses copper material to more easily die-cast these smaller blocks, but it is difficult to form other materials for die-casting, but the cost of copper blocks is high and the overall production cost is high. The present application uses stainless steel as the material to reduce the cost of raw materials, and at the same time welds the connecting blocks by welding. Stainless steel has good strength and corrosion resistance. Compared with the harder stainless steel produced by die-casting, this method is easier to form, further reducing the processing cost. The connecting blocks and connecting rings are also produced by stainless steel, which can improve the overall strength and corrosion resistance of the product, thereby further improving production efficiency and product quality.

[0023] 2. The present application also provides a fitting portion and a welding ring groove. The fitting portion of the connecting block can improve the fit during welding, making the fitting between the connecting block and the stainless steel shell tighter, thereby improving the welding quality after welding. The welding ring groove can make way for the welding point, thereby reducing the restrictions during welding, making way for the welding equipment, and reducing interference during welding, thereby further improving the efficiency and effect of welding and further improving product quality.

[0030] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0031] A water meter housing, such as Figure 1 and Figure 2As shown, it includes a stainless steel housing 1, which is provided with a through hole 11, which is located in the middle of the stainless steel housing 1. The inner wall of the stainless steel housing 1 is provided with internal threads 12. A plurality of connecting blocks 2 are provided on the outer wall of the stainless steel housing 1, and the connecting blocks 2 are connected to the stainless steel housing 1 by welding. In specific implementation, the stainless steel housing 1 is formed by winding and welding or die-casting stainless steel sheets, and then the pre-cast connecting blocks 2 are fixed to the stainless steel housing 1 by welding. During installation, they are placed on the corresponding water meter, and the connecting blocks 2 are installed by embedding into the corresponding groove, thereby completing the installation of the water meter. It is also possible to wrap the water meter with a plastic shell after installation.

[0032] like Figure 1 and Figure 2 As shown, the connecting blocks 2 are arranged at equal intervals along the side wall of the stainless steel shell 1. In specific implementation, four connecting blocks 2 are provided on the stainless steel shell 1 in this embodiment, and the connecting blocks 2 can just support and install the stainless steel shell 1 from four directions.

[0033] like Figure 1 and Figure 2 As shown, the connection blocks 2 are provided with connection holes 21 for the connection wires to pass through. In specific implementation, iron wire or iron wire can pass through the connection holes 21 to install the connection blocks 2, further improving the convenience of installation.

[0034] like Figure 1 and Figure 2 As shown, a fitting portion 22 is provided on one side of the connecting block 2 close to the stainless steel housing 1. The fitting portion 22 corresponds to the shape of the stainless steel housing 1 and abuts against the side wall of the stainless steel housing 1. In a specific implementation, the fitting portion 22 is arc-shaped and can fit on the stainless steel housing 1. After the stainless steel housing 1 is fitted, it can be further welded tightly to the stainless steel housing 1, which can improve the efficiency and effect of welding.

[0035] like Figure 1 and Figure 2 As shown, the stainless steel housing 1 is further provided with a limiting cylinder 3, which is integrally provided with the stainless steel housing 1 and has a diameter smaller than that of the stainless steel housing 1. In specific implementation, the limiting cylinder 3 and the stainless steel housing 1 are connected by winding stainless steel sheets or die-casting. The limiting cylinder 3 can not only limit the position of the pipeline, but also connect two pipelines to each other.

[0036] like Figure 1 and Figure 2As shown, a limiting ring 31 is also provided on the limiting cylinder 3. The limiting ring 31 is fixedly connected to the limiting cylinder 3. The middle part of the limiting ring 31 is penetrated and communicated with the through hole 11. The limiting ring 31 is used to abut the pipeline.
