[Meter's latest patent] a water meter

Content Description

The present invention relates to a water meter, and more particularly to a water meter capable of quick installation and disassembly of an additional component and a water meter mechanical component.

Background of the invention

With the development of electronic technology and the Internet of Things, smart water meters have also been universally developed. At present, smart water meters basically use traditional mechanical water meters to install electronic components. The existing water meter product has many structural components and many installation steps, and the whole needs to be screwed on the copper cover. When disassembling, some plastic parts may be destroyed to remove the screw. The electronic parts of the smart meter are easily damaged compared with the mechanical parts, and the maintenance cost of the electronic parts is high. When the electronic parts are replaced, it is necessary to re-calibrate each time, it is difficult to achieve rapid installation, and the recovery cost of the electronic parts is high. For some users who have not yet used the smart water meter, if they need to install the smart water meter on the basis of the mechanical water meter in the later period, they may encounter troubles in the modification, and even need to replace the mechanical water meter as a whole.

Summary of the Invention

In view of the problems existing in the prior art, the present invention adopts a snap-in connection method to simplify the installation and disassembly of the water meter mounting part and the mechanical part by simplifying the installation fittings of the water meter attachment part, thereby improving the installation of the water meter attachment part. Replace maintenance efficiency.

In order to achieve the above object of the invention, the technical scheme adopted by the invention is as follows: a water meter includes a mechanical body of a water meter, a copper cover and an outer cover, an outer cover is provided with an upper cover, and the water meter further includes a connecting member connecting the copper cover and the outer cover, and the connection The parts are fastened to the top of the copper cover by screws, and a fastening device is provided between the connection part and the cover. The fastener device includes a plurality of buckles disposed on the inner wall of the top of the shell and a plurality of card slots disposed on the connector. The buckle includes a connecting piece and a chuck of the end of the connecting sheet. The card slot matches the buckle and includes a guide slot. And limit slots that communicate with the guide slot. When installing, cover the cover on the top of the connector, and the buckle corresponds to the slot one by one. The clamp head is inserted into the guide slot to press down and rotate into the limit slot to complete the buckle of the cover and the connector; the buckle is connected to the connector. The upper cover rotates in the opposite direction, and the chuck head is turned from the limit slot to the guide slot, so that the cover part can be easily removed.

Further, in order to make the outer cover and the connecting member engage more firmly, the snaps are arranged in pairs, two rows of snaps are arranged along the rotational direction of the snap, the connecting pieces of each pair of snaps are arranged in parallel, and the clips are located at two connections. On the outside of the opposite side of the sheet, the card slots on the connection sheet are arranged in pairs and matched with the buckles. In order to prevent the cover from being easily rotated and removed, there is a disassembly and protection device between the cover and the connector. The disassembly and protection device includes a nut mounting hole and a first groove provided on the connector, and a screw hole provided on the cover. And the second groove, and the bottom and the second groove are matched with the limiting member for covering the second groove. After the cover and the connecting member are clamped by the buckle, the cover and the connecting member are fastened by the screw, and the limit is limited. The positioning member is inserted into the second groove, covers the screw and the second groove, restricts rotation between the cover and the connector, and the cover of the cover is movably mounted on the limiting member.

For mechanical water meters without electronic components, the cover is a simple protective cover. For water meters with electronic components, the electronic housing containing electronics can be placed on the cover to accommodate electronic components such as electronic devices, batteries, and antennas. According to the required accessories, the electronic device housing includes, but is not limited to, an inductive device receiving cavity, an antenna receiving cavity, a battery receiving cavity, and a through hole, etc., and the battery is accommodated to facilitate replacement of the electronic component battery. One end of the cavity is provided with a detachable plug, and a waterproof ring is provided on the plug. When it is necessary to install electronic components on the mechanical water meter, it is only necessary to remove the protective cover of the mechanical water meter, and the copper cover and the connector do not need to be changed, and the cover with the electronic device can be quickly installed and replaced, and the conversion is very convenient. When there is a problem with the electronic components of the water meter that needs to be replaced, remove the cover and replace it with a new one.

Compared with the prior art, the present invention has the following advantages: 1. The present invention changes the way in which a conventional mechanical water meter attachment component is directly fixed on a copper cover by means of screws, and a connection piece is set on the copper cover through the buckle. The connection method connects the installation components, which realizes the quick engagement and separation of the added components and the mechanical components, and improves the installation and disassembly speed of the attached components. 2. For the water meter equipped with electronic components, the separation of the electronic components from the mechanical components is realized, which makes the installation and replacement of the electronic components more convenient, and improves the recyclability of the electronic components and reduces the production cost. 3. When the mechanical water meter is converted into a smart water meter, the installation is simple and easy to implement.
