[Meter's latest patent] An easy-to-remove split water meter

[Chinese instrument network meter patent] creative limit, instrumentation invention. Today we introduce a national patent for invention—an easy-to-remove split water meter. The patent was applied for by Jiangsu Saida Electronic Technology Co., Ltd. and was authorized to be announced on August 1, 2017.

Content Description

The invention relates to a water meter, in particular to an easily disassembled split water meter for realizing quick installation and separation of an electronic component and a meter body.

Background of the invention

With the development of sensor technology and communication technology, as well as the demand of water supply companies for accurate metering and intelligent management of water meters, smart water meters have also gained widespread development. People's research on smart water meters is more focused on how to measure more accurately and more intelligent management, and often overlooks the convenience of installation and maintenance. The use of magnetic sensor technology, can achieve the electromechanical separation of the water meter, Figure 1 is a wireless remote water meter of the existing, but its structural deficiencies are as follows: 1, mechanical water meter above the structural components of the electronic component housing Many, many installation steps, the overall need to use screws to fasten on the mechanical water meter, you may need to destroy some plastic parts to remove the screws. 2. The battery box has a small space, and the box cover is placed in the box body. The battery replacement requires special tools and the operation is inconvenient.

Summary of the Invention

In view of the above technical problems, the present invention provides a split type design of an electronic component and a water meter mechanical body by simplifying the structural components of the electronic component case and the connection to the water meter mechanical body, and is convenient for achieving the above-mentioned object of the invention and the technology adopted by the invention. The scheme is as follows: An easy-to-remove split type water meter includes a water meter mechanical body, a shell and an upper cover, an electronic component box and a battery box on the outer shell, the electronic element box includes an electronic element shell and a cover plate, and the battery box includes a battery shell. And the cap, the water meter further comprises a connecting member connecting the mechanical body of the water meter and the shell, the connecting member is fixed on the mechanical body of the meter by screws, the inner sidewall of the shell is provided with a buckle, and the outer side of the connecting member is The wall is provided with a card slot that matches the buckle.

The figure is a schematic structural diagram of an embodiment of the present invention

Further, a limiting member and a screw fixing device are disposed between the shell and the connecting member to prevent the shell from being easily disassembled. The connecting member is provided with a first groove matching the bottom of the limiting member, and the bottom of the first groove is provided with a nut. The mounting hole is provided with a lug on the inner side wall of the shell, a screw hole is arranged on the lug, and the shell and the connection piece are fixed by screws; the bottom surface of the limit element is provided with a bump and a second groove matched with the lug. The bottom surface of the first groove is provided with a third groove that matches the bump.

The top cover is mounted on the upper part of the limiter. Two cylinders are arranged on the upper cover, and a circular through groove matched with the cylinder is arranged at the upper part of the limiting member, and the two cylinders are respectively snapped into the two ends of the circular through groove, and the upper cover can be the shaft of the circular through groove. Flip for axis. In order to facilitate battery replacement, the battery case is arranged perpendicular to the surface of the water meter. The cap is located above the battery case. The upper side of the battery case and the inside of the cap are provided with threads, and the battery case is screw-connected with the cap.

When installing, fix the connecting piece to the mechanical water meter by screws. Place the nut in the nut mounting hole of the connecting piece. The housing cover is on the connecting piece. When the buckle and the slot are aligned and rotated, the buckle and the slot are locked. Fix the shell and connector with a screw, and insert the limiting member into the first groove on the connector. Align the protrusion on the limiting member with the third groove on the connector and press the limiting member. Then, insert the two columns of the upper cover into the two ends of the circular channel at the upper part of the limiter to complete the installation.

When the electronic components are repaired and replaced, the upper cover is first removed from the limiting member, the limiting member is pulled out, the screw is unscrewed, and the housing is removed by rotation, and the entire device can be replaced with a new one. If the water meter's upper cover or limiter is broken, because they are all parts that are easy to dismantle, just replace the accessories and do not need to replace the whole.

Compared with the prior art, the present invention has the following advantages: 1. It simplifies the structural components of the electronic component housing and uses a snap connection method to connect with the main body of the mechanical water meter, achieving quick installation and maintenance replacement. 2. The buckle and the card slot are disposed on the largest side of the contact surface of the electronic component case and the connecting member, and a larger buckle and a card slot can be provided, the strength of the buckle and the connection are improved, and the installation is more convenient. 3, fewer electronic components, the overall shape, easy to replace. 4. The battery box is vertically set and the cap is external to facilitate battery replacement.
