[0035] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0036] An embodiment of the present application discloses a housing of a flow sensor.

[0037] Reference Figure 1 、 Figure 3 、 Figure 5 A shell of a flow sensor includes a main shell 1, which is square as a whole and hollow inside the main shell 1. A power supply cavity 21 is set at the top of the hollow. At the same time, an upper through hole 2 is opened inward on the upper end surface of the main shell 1. The upper through hole 2 passes through the main shell 1 and is connected to the power supply cavity 21. An upper shell 4 is inserted at the position of the upper through hole 2 on the upper end surface of the main shell 1. Two rotation grooves 5 are opened on one side surface of the upper shell 4, and a rotating shaft 6 is inserted into the inner wall of the two rotating grooves 5. The rotating shaft 6 is located on the surface of the two rotating grooves 5 and is rotatably connected with a connecting block 8. The top surfaces of the two connecting blocks 8 are fixed with an upper cover 7. A threaded hole is opened on the top of the upper cover 7, and a hand screw 9 is threadedly connected in the threaded hole, and the bottom of the hand screw 9 is threadedly connected to the upper end surface of the main shell 1.

[0038] It should be noted that the top surface of the upper shell 4 is provided with existing structures such as control buttons and a display screen. Four screw holes are opened on the top surface of the upper shell 4 around the control buttons and the display screen, and anti-slip screws 10 are threadedly connected in the screw holes. The anti-slip screws 10 are threaded into the threads and threadedly connected to the upper end face of the main shell 1 to form a fixation. At the same time, the widths of the main shell 1, the upper shell 4 and the upper cover 7 are consistent and the centers are aligned.

[0039] A power supply module for storing electrical energy is fixedly installed in the power supply cavity 21 to provide electrical energy to the device. At the same time, the main shell 1 reserves an installation cavity for the installation of the power supply module and provides support. The upper shell 4 is fixed on the top of the main shell 1, so that personnel can adjust the device through the control buttons and display screen, and the two rotating grooves 5 are plugged with the rotating shaft 6, so that the two connecting blocks 8 are selected with the rotating shaft 6 as the center, and then the two connecting blocks 8 drive the upper cover 7 to rotate synchronously. As the upper cover 7 is opened and closed, it abuts against the upper shell 4, thereby sealing and protecting the control buttons and display screen of the upper shell 4 to form a switch.

[0040] Reference Figure 1 、 Figure 4 、 Figure 5Side openings 12 are provided at both ends of the side surface of the main shell 1, and the two side openings 12 pass through the side wall and are connected to the power supply cavity 21. The surfaces of the two side openings 12 are screwed with side covers 13, and the connection between the two side covers 13 and the side openings 12 are glued and fixed with sealing rings 24. At the same time, the upper end surface of the main shell 1 is provided with a mounting groove 13 inwardly around the upper opening 2, and the upper end surface of the upper shell 4 is provided with a mounting groove 2 11 inwardly around the control button and the display screen. The mounting groove 1 3 and the mounting groove 2 11 are also glued and fixed with sealing rings 24, and the bottom surfaces of the upper cover 7 and the upper shell 4 are both concave, the upper cover 7 and the upper shell 4 abut to form an interactive cavity 23, and the upper shell 4 abuts against the main shell 1 to form a mainboard cavity 22.

[0041] The interactive cavity 23 between the upper cover 7 and the upper shell 4 reserves a cavity for the operation buttons and display screen on the surface of the upper shell 4 to prevent misalignment. At the same time, the operation buttons and the display screen of the upper shell 4 are connected to the mainboard cavity 22 through lines. An operation circuit board is fixed in the mainboard cavity 22, and the operation circuit board is connected to the power supply module in the power supply cavity 21 through lines, so that the operation circuit board receives the feedback signal transmitted by the operation button, and then the two side covers 13 are sealed and connected to the main shell 1, thereby providing auxiliary support to the main shell 1 while maintaining the sealing inside the main shell 1.

[0042] Reference Figures 2 to 5 The internal cavity of the main shell 1 is located at the bottom of the power supply cavity 21 and is set as a connecting cavity 20. The bottom of the connecting cavity 20 passes through the main shell 1 and is connected to the outside, and a lower through-hole 14 is provided, and a mounting interface 19 is fixed at the opening at the top of the lower through-hole 14. The lower through-hole 14 is plugged into the docking interface of the flow meter 18, and a sealing ring 17 is glued and fixed at the position where the outer surface of the flow meter 18 is connected to the lower through-hole 14. At the same time, the outer surface of the lower through-hole 14 is provided with a groove around the connection with the flow meter 18, and a quick-connect spring 15 is movably inserted in the groove. The quick-connect spring 15 can be tightened to fix the flow meter 18. Two glands 16 are fixed on one side of the lower through-hole 14 on the bottom surface of the main shell 1. The tops of the two glands 16 pass through the main shell 1 and are connected to the connecting cavity 20.

[0043] The connection cavity 20 is installed with connection modules and docking line structures, so that it is compatible with plug-in connectors, Holzmann street connectors and other connectors. The gland 16 is connected to the external cable, and the inner wall of the gland 16 fixes the cable to keep the cable and the connector connected. At the same time, the flow meter 18 is inserted into the connection cavity 20 from the lower port 14 and docked with the installation interface 19, and the quick-connect spring 15 is tightened to shrink the lower port 14, thereby assisting in fixing the flow meter 18. At the same time, the sealing ring 17 seals the flow meter 18 with the lower port 14 to maintain the sealing inside the main shell 1.

[0044] Among them, the device also includes a hand screw 9, an anti-slip screw 10, a cable gland 16, and a flow meter 18, which are all existing technologies and their structures are not described in detail.

[0045] The implementation principle of the housing of a flow sensor according to an embodiment of the present application is as follows: when installing the housing, the power supply module that provides electrical energy is inserted into the power supply cavity 21 through the side opening 12, and the power supply module is docked with the circuit structure such as the computing circuit board. Then, the two side covers 13 are abutted against the side opening 12 and fixed with screws at four diagonal positions to improve the stability of the main housing 1.

[0046] Then, the personnel insert the interface of the flow meter 18 into the connecting cavity 20 through the lower opening 14 and dock it with the installation interface 19. The installation interface 19 fixes the flow meter 18 while maintaining the connection between the flow meter 18 and the operation circuit board control system. The hand screw 9 is turned to cancel the fixed state between the upper cover 7 and the upper shell 4, thereby rotating the upper cover 7 to expose the control buttons and display screen on the surface of the upper shell 4. The display screen displays data parameters in real time, and the system number is adjusted by controlling the movement of the control buttons, thereby receiving data transmitted by the flow meter 18.

[0047] While the flow meter 18 is transmitting data, the top of the main shell 1 is sealed with the upper shell 4 through the sealing ring 24, and the top of the upper shell 4 is sealed with the upper cover 7 through the sealing ring 24. The two side covers 13 are fixed to both sides of the main shell 1 through the sealing ring 24. Finally, the flow meter 18 and the lower port 14 are kept sealed by the sealing ring 17. The azimuthally synchronized sealing ensures the sealing of the internal structure of the main shell 1, effectively preventing the internal structure from coming into contact with external dust and other debris during the operation of the device, thereby causing damage.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
