Description

Technical Field

[0001] The utility model relates to a water meter, in particular to a meter cover component suitable for various types of water meters. Background Art

[0002] Among the existing water meters, including direct-reading valve-controlled water meters, wireless direct-reading water meters and wired direct-reading water meters, these types of water meters are equipped with correspondingly designed meter cover assemblies, which include a meter cover and a box body integrally formed with the meter cover and used to install batteries, valve control devices (activators that can be used to open or close the water meter valve) or other components. The meter cover assemblies of these types of meters are not universal, and the mold development costs required are high, and the applicability is too narrow, which brings many inconveniences to production plans. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a meter cover assembly which has a simple structure, strong compatibility and can be widely applied to various types of water meters.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a meter cover assembly for a water meter, comprising a meter cover snapped onto a meter case, and is characterized in that the meter cover comprises an integrally formed lower base and an upper ring cylinder, and a quick-connect portion protruding outward and integrally formed with the lower base is provided on the outer peripheral wall of the lower base, and the quick-connect portion can be quickly snapped onto various types of external hanging boxes.

[0006] The quick-connect part is composed of an upper clamping part and a lower clamping part. The upper clamping part is rectangular in shape, and a protrusion extending upward is provided on the top surface of the rectangle. A threaded hole is provided in the middle of the top surface of the protrusion, and a certain gap is left between the inner side of the protrusion and the upper ring tube; the lower clamping part is arranged on the outer peripheral wall of the lower base, and is shaped like a rectangle with a left and right width greater than the width of the upper clamping part, and a clamping groove is provided at the bottom of the left and right sides of the lower clamping part.

[0007] The middle of the lower clamping part is a hollow part through which a wire can pass.

[0008] The bottom of the external box is a closed structure, the top surface is open, and the inside of the box is a storage chamber for installing batteries and / or valve control devices. On the outer wall of the external box opposite to the quick-connect part, there is a connecting part that cooperates with the male and female parts of the quick-connect part. The connecting part includes a fixing groove that can be engaged with the protrusion and an edge guide rail that can be inserted into the slot.

[0009] Compared to existing technologies, the present invention designs the meter cover assembly into a meter cover and an external box. The shape and size of the meter cover or external box can be designed to suit the functions of water meters with different functions. A quick-disassembly mechanism is provided between the meter cover and the external box. This quick-disassembly mechanism is unique for the covers and external boxes of water meters with different functions. When producing a certain type of water meter, only the appropriate meter cover and external box need to be connected together. Alternatively, the covers of all types of water meters can be designed in the same style, and the appropriate external box can be quickly connected based on their functions. This structural design can significantly reduce mold development costs, simplify management content during production management, and reduce inventory management burdens.

DETAILED DESCRIPTION

[0016] like Figure 1-4 As shown, the meter cover assembly 1 used on the water meter of the utility model is suitable for general direct-reading valve-controlled, wired direct-reading, wireless direct-reading and other water meters. It mainly sets a universal quick-connect structure on the side of the meter cover 2 of the above-mentioned types of meters. Such meters usually include a base meter and supporting components such as a power supply and valve control device provided on the side of the base meter for the base meter. In the prior art, the box body accommodating the supporting components and the meter cover 2 are an integrally formed structure, and its defects are as described in the "Background Technology" of this specification.

[0017] The specific structure of the watch cover assembly 1 of the present utility model is as follows:

[0018] The watch cover assembly 1 consists of a watch cover 2 and an external box 3.

[0019] The meter cover 2 is mounted on the meter case 4 and includes a lower base 27 and an upper ring tube 28. The lower base 27 and the upper ring tube 28 are an integral injection-molded structure. A quick-connect portion protruding outward and integrally formed with the lower base 27 is provided on the outer peripheral wall of the lower base 27. The quick-connect portion can be quickly connected to various types of external plug-in boxes 3 respectively; these external plug-in boxes 3 include box bodies that accommodate supporting components of direct-reading valve-controlled water meters, wired direct-reading water meters, and wireless direct-reading water meters. These box bodies are of different sizes and the installed supporting components are also different.

[0020] The quick-connect part is composed of an upper clamping part 21 and a lower clamping part 22. The upper clamping part 21 is rectangular in shape, and a protrusion 23 extending upward is provided on the top surface of the rectangle. A threaded hole 24 is provided in the middle of the top surface of the protrusion 23, and a certain gap is left between the inner side of the protrusion 23 and the upper ring tube 28; the lower clamping part 22 is arranged on the outer peripheral wall of the lower base 27, and is shaped like a rectangle with a left and right width greater than the width of the upper clamping part 21, and a clamping groove 25 is provided at the bottom of the left and right sides of the lower clamping part 22.

[0021] The middle of the lower clamping portion 22 is a hollow portion 26 through which a wire can pass. The wire is used to electrically connect the circuit board inside the meter with the matching components in the external box 3. The electrical connection includes electrical signal connection and power supply connection.
