[0020] The following is combined with Figures 1 to 6 The utility model is described in detail.

[0021] The utility model provides a hidden flow meter, comprising a trough-shaped shell 1 and a metering device 2, wherein the metering device 2 is provided with a connecting pipe 21, which is used to connect a water pipe. A sensor 22 is provided on the connecting pipe 21, which can collect flow data in the connecting pipe 21, and the sensor 22 is provided with a wire pipe 23, which is made of metal and can be fixed to the inner wall of the trough-shaped shell 1. The metering device 2 is provided with a fixing seat 3 installed in the trough-shaped shell 1, a groove 31 for fixing the wire pipe 23 is provided at the bottom of the fixing seat 3, and a slide groove a32 is provided at the top of the fixing seat 3, the metering device 2 is provided with a control device 4 electrically connected to the sensor 22, the control device 4 is provided with a slide rail 41 movably connected to the slide groove, a display panel 42 and a slot 43 are provided on the front of the control device 4, a battery compartment 44 is provided on one side of the control device 4, and a signal transmitter 45 is provided on the back of the control device 4. The flow meter of the present invention is an electronic instrument for measuring the water flow in a water pipe. During installation, the trough-shaped housing 1 is first installed on the installation position reserved on the wall, so that the trough-shaped housing 1 is embedded in the wall, so that the control device 4 of the metering device 2 can be hidden in the wall. This structure can reduce the influence of the external environment on the control device 4 and greatly extend the service life of the instrument. More specifically, by connecting the slide groove a32 and the slide rail 41, the control device 4 can be moved back and forth, and the slot 43 can facilitate the user to control the mobile control device 4. The user can move the control device 4 out of the trough-shaped housing 1 and operate the control device 4. The control device 4 of the flow meter has an internal circuit structure. By assembling and replacing the mobile power supply in the battery compartment 44 to provide power to the flow meter 2, the display can display the data transmitted by the sensor 22. No external power supply wires are required, and the safety performance is high. A limit frame 11 is provided at the opening of the trough-shaped shell 1. A door panel 12 that can move up and down is provided in the limit frame 11. The top of the door panel 12 passes through the limit frame 11 and is provided with a limit block 13. The bottom of the door panel 12 is provided with a notch 14 corresponding to the wire tube 23. A protrusion 15 is also provided on the door panel 12. The trough-shaped shell 1 is closed by the door panel 12, and the control device 4 is completely hidden in the wall, preventing the control device 4 from being affected by high humidity, windy and sandy environments, etc., and having strong protective capabilities. The door panel 12 can be lifted by simply lifting the protrusion 15 with a finger, releasing the support for the door panel 12, and the door panel 12 naturally falls due to gravity. The limit hole abuts the outside of the limit frame 11 to fix the door panel 12. In addition, the flow meter can transmit the flow measurement data and battery power status to the terminal device through the signal transmitter 45. The flow measurement monitoring personnel can receive the data without going to the site, which is convenient and intelligent to use.

[0022] The trough-shaped housing 1 is rectangular and has four side panels 101 and a back panel 102. The middle portion of the wire tube 23 abuts against at least one of the side panels 101. One end of the wire tube 23 is provided with a bent portion 24 that abuts against the back panel 102. The bent portion 24 is provided with a connecting piece 25. The bent portion 24 and the middle portion of the wire tube 23 form an L-shape. After the fixing base 3 is installed in the trough-shaped housing 1, the fixing base 3 fixes the middle portion of the wire tube 23. The connecting piece 25 can be driven into a nail. The nail passes through the connecting piece 25 and the back panel 102 and is inserted into the wall, thereby fixing the bent portion 24 to the trough-shaped housing 1 and further strengthening the connection between the trough-shaped housing 1 and the wall.

[0023] The bent portion 24 is provided with a magnetic member 26, and the back of the control device 4 is provided with an iron plate 46 that can be magnetically connected to the magnetic member 26. The magnetic member 26 and the iron plate 46 can fix the position of the control device 4 in the groove-shaped housing 1, and the control device 4 will not slide out naturally after the door panel 12 is opened, thereby providing high stability.

[0024] The top of the fixing base 3 is provided with a fixing block 33, and the bottom of the control device 4 is provided with a sliding groove b47 that cooperates with the fixing block 33. The sliding groove b47 has a certain length, and the fixing block 33 moves relatively within the sliding groove b47. The length of the sliding groove b47 is the sliding distance of the control device 4. This structure prevents the control device 4 from detaching from the fixing base 3.

[0025] The fixing base 3 is provided with a positioning hole 34, in which a bolt 35 is provided. The positioning hole 34 is T-shaped, and the bolt 35 can pass from the top of the fixing base 3 through the positioning hole 34, through the bottom of the fixing block 33, and connect to the side plate 101, so that the fixing base 3 is fixed in the groove-shaped housing 1. After the fixing base 3 is installed and fixed, the top of the bolt 35 can be hidden in the positioning hole 34.

[0026] A plurality of control keys 48 are provided on the other side of the control device 4. The control keys 48 can control the display screen switch, the power switch of the control device 4, etc.

[0027] The wire conduit 23 is fixedly connected to the connecting pipe 21. Since the trough-shaped housing 1 is embedded in the wall and fixedly connected to the wall, the wire conduit 23 is fixedly connected to the trough-shaped housing 1. Therefore, the fixed connection between the wire conduit 23 and the connecting pipe 21 can improve the stability of the connecting pipe 21, reduce the vibration amplitude of the connecting pipe 21 caused by external forces, and improve the accuracy of flow measurement data.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
