Description

Technical Field

[0001] The utility model relates to the technical field of water meter boxes, in particular to a multifunctional water meter box. Background Art

[0002] At present, the water meter industry market is in a stage of rapid development. With the acceleration of urbanization, the demand for water resource detection and management is increasing, and water meters are widely used as an important tool for water resource management. The market demand for water meters is growing rapidly, and diversified application needs are emerging. Water meters are not only in strong demand in the field of residential water use, but are also widely used in other fields. With the development of the water meter industry, the demand for water meter boxes has also grown rapidly. At present, the water meter boxes in the water meter industry basically have an upper cover and a base. There are two ways to connect the upper cover and the base. One is to fix the upper cover and the bottom of the table by screw lock, and the other is to fix the upper cover and the bottom of the table by buckle. The materials used for the upper cover and the base are basically the same, either all plastic or all cast iron.

[0003] For example, the Chinese authorized patent "A Water Meter Box" with announcement number CN216206736U includes a water meter box body, which is composed of an upper shell, a lower shell and a cover plate. The interior of the water meter box body is a hollow cavity, a top opening is opened on the top of the upper shell, and a cover plate is threadedly connected to the top opening. Reinforcement plates 1 are evenly arranged on the side of the upper shell, reinforcement plates 2 are evenly arranged on the side of the lower shell, reinforcement plates 3 are evenly arranged on the top of the upper shell, and reinforcement ribs are evenly arranged in an array around the top periphery of the lower shell. The upper shell, the lower shell and the cover plate are all composed of a plastic layer and a flame retardant layer. Flame retardant layers are respectively provided on the inner and outer sides of the plastic layer, and the material of the plastic layer is polytetrafluoroethylene.

[0004] Most of the existing technologies use screws. If there is a problem with the meter inside the meter box, it will be difficult to open the meter box because it is installed underground. There are risks in using snap-on methods. There is a risk of the water meter being stolen. Secondly, there will be groundwater and water droplets when it is installed underground. The meter box is not sealed, so water will accumulate inside. Over time, a lot of water will accumulate in the meter box, which will cause corrosion to the meter box, water meter, and pipelines. In addition, the meter box is made entirely of cast iron, which is expensive. Moreover, the meter box is made entirely of plastic, which has low pressure resistance and is not as good as cast iron. If it is subjected to too much pressure, the bottom of the meter will crack. Therefore, it does not meet the existing needs. In this regard, we have proposed a multifunctional water meter box. Utility Model Content

[0005] The utility model aims to provide a multifunctional water meter box to solve the problems of poor assembly and disassembly flexibility of the water meter box, easy water accumulation inside the box and inconvenient handling proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional water meter box, comprising a base; an upper cover is arranged above the base, and the edges of the base and the upper cover are limited by a slot, a top cover is installed on the top of the upper cover, and the top cover is movably connected to the upper cover, a lock body is installed on one side of the top cover for fixing with the upper cover, handrails are symmetrically arranged on both sides of the base, and the handrails are in a raised structure, and the bottom of the base is provided with drainage holes symmetrically distributed along the center line of the base, and the drainage holes are communicated with the inner cavity of the base.

[0007] Preferably, a rotating shaft is provided on one side of the top cover, and the rotating shaft is rotatably connected to an inner wall of one side of the opening on the upper cover, and the other side of the top cover is supported by the other side of the opening on the upper cover.

[0008] Preferably, base mounting ears are integrally cast at the four corners of the outer edge of the upper end surface of the base, and upper cover mounting ears are injection molded at the four corners of the outer edge of the bottom of the upper cover, and the base mounting ears are fixed to the upper cover mounting ears by bolts.

[0009] Preferably, at least six drainage holes are provided.

[0010] Preferably, the armrest and the base are integrally cast, and the inner wall of the base has a concave structure at a position corresponding to the armrest.

[0011] Preferably, the base is made of cast iron, and the upper cover and top cover are made of high-strength plastic.

[0012] Preferably, longitudinally distributed reinforcing ribs are provided on the outer walls of the base and the upper cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model provides a movably installed top cover on the top of the upper cover, and installs a lock body matched with the upper cover on the top cover. After installation, the lock body can be locked to achieve the closure of the entire water meter box, which effectively increases the safety. When it needs to be opened, it only needs to use a key to open the lock body and pull out the top cover to open the box, which is convenient for daily maintenance operations. This structure can not only overcome the problem that the meter box is difficult to open due to screw fixation, but also avoid the risk of water meter theft caused by conventional buckle structure, and the practicality is effectively improved.

[0015] 2. The utility model sets drainage holes symmetrically distributed along the center line of the base at the bottom of the base. The drainage holes are connected to the inner cavity of the meter box. With long-term use, water droplets generated inside the meter box will condense, gather to the bottom of the meter box under the action of gravity, and finally be discharged from the drainage holes, effectively avoiding the risk of corrosion to the meter box, water meter and pipelines.

[0016] 3. The utility model integrally forms handrails by die-casting on both sides of the base. The handrails are of a convex structure. The staff can take and move the meter box by holding the handrails, which effectively improves the convenience. Moreover, the handrails are of a concave structure corresponding to the inner side of the base, which effectively saves the use of cast iron materials and reduces the production cost.

[0017] 4. The upper cover and top cover of the utility model are made of plastic, and the base is made of cast iron. Since the upper cover has less contact around it and the pressure on it is also lower, the use of high-strength plastic can not only meet the use requirements but also effectively reduce production. The base is in contact with the ground for a long time. The high strength and high pressure resistance of cast iron can ensure that the meter box is underground for a long time without cracking, effectively improving the service life of the meter box.
