[0001] This utility model relates to the field of water meter technology, and in particular to an ultrasonic water meter head that is easy to maintain. Background Technology
[0002] An ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of an ultrasonic beam as it propagates upstream and downstream in water, analyzes and processes the data to obtain the water flow rate, and then calculates the water flow rate.
[0003] Traditional ultrasonic water meters have highly integrated internal components such as circuit boards, display boards, and batteries. Some structures are waterproofed by being filled with glue, making them difficult to replace individually if damaged, which increases maintenance costs. Utility Model Content

If they are damaged, they are difficult to replace individually, which increases the maintenance cost. Therefore, this utility model proposes an ultrasonic water meter head that is easy to maintain.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An easily maintainable ultrasonic water meter head includes a meter housing and a detachably connected upper cover. A lower cover is also installed inside the meter housing. A display module and a control module are housed within the lower cover, and are plugged into each other. The control module is snapped into the lower cover. The display module includes a display board, and the control module includes a control board. The display board is snapped into the control board. A battery is housed inside the meter housing, and the battery and control board are isolated and separated by the lower cover.
[0007] Preferably, the top cover and the watch case are fastened together by bolts.
[0008] Preferably, a cavity is provided at the center of the top cover of the watch case, and a watch head cover is rotatably connected inside the cavity.
[0009] Preferably, a transparent cover is provided inside the upper cover of the watch case, and the transparent cover is placed on the lower cover of the watch case.
[0010] Preferably, the lower cover of the watch case is provided with an integrally formed, stepped annular strip, which is located inside the transparent plate of the watch case.
[0011] Preferably, the control board is provided with at least one positioning groove, and the lower cover of the watch case is provided with multiple positioning pins. The arrangement of the multiple positioning pins matches the shape of the control board and limits and fixes the control board. The positioning groove is engaged with one of the positioning pins.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] It is easy and practical to maintain, solving the problem of not having to send damaged parts back to the factory for repair. Each part can be installed in a modular manner, and the internal battery and control board are separated, which facilitates the replacement of each module and allows for easy replacement of individual parts if they are damaged. Attached Figure Description
[0014] Figure 1 This is an exploded structural diagram of an ultrasonic water meter head that is easy to maintain, as proposed in this utility model.
[0015] In the diagram: 1. Top cover of the watch head; 2. Top cover of the watch case; 3. Transparent panel of the watch case; 4. Watch case; 5. Bottom cover of the watch case; 6. Display panel; 7. Battery; 8. Control panel; 9. Positioning slot; 10. Positioning pin. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0017] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0018] Reference Figure 1 An easy-to-maintain ultrasonic water meter head includes a meter housing 4 and a detachably connected upper cover 2. The upper cover 2 and the meter housing 4 are fastened together by bolts. Installation and disassembly can be quickly completed by reversing the direction of rotation using a screwdriver or similar tool. A lower cover 5 is also installed inside the meter housing 4. The lower cover 5 houses a display module and a control module, which are plugged into each other. The control module is snapped into the lower cover 5. The display module includes a display board 6, and the control module includes a control board 8. The control board 8, also known as a circuit board or circuit board, is commercially available. Its working principle is not described in detail. The display board 6 is snapped onto the control board 8. The structure of different functions is modularly designed, and each module is connected by plug-in connections. This eliminates the need for returning damaged parts to the factory for repair; only individual damaged parts can be replaced, making replacement easier and more convenient. Modular installation also makes the process more convenient.
[0019] The battery 7 is installed inside the watch case 4. The battery 7 and the control board 8 are separated by the lower cover 5 of the watch case. The battery 7 is independently installed inside the watch case 4 and is separated from the control board 8, which facilitates the replacement and installation of the battery 7.
[0020] A cavity is provided in the center of the top cover 2 of the watch case, and the top cover 1 of the watch head is rotatably connected inside the cavity. When observing the display panel 6, the top cover 1 of the watch head can be rotated open.
[0021] A transparent case plate 3 is provided inside the upper cover 2 of the watch case. The transparent case plate 3 is placed on the lower cover 5 of the watch case. An integrally formed, stepped annular strip is provided on the lower cover 5 of the watch case. The annular strip is located inside the transparent case plate 3. The transparent design of the transparent case plate 3 makes it easier to observe the multiple internal modules and the display on the display panel 6. Moreover, the transparent case plate 3 covers the display module and control module, which protects the internal components. The annular strip acts as a limit, which can restrict the transparent case plate 3 and prevent it from detaching from the lower cover 5 of the watch case.
[0022] The control board 8 is provided with at least one positioning groove 9, and the lower cover 5 of the case is provided with multiple positioning pins 10. The arrangement of the multiple positioning pins 10 matches the shape of the control board 8 and limits and fixes the control board 8. The positioning groove 9 is locked on one of the positioning pins 10. When installing the control board 8, the positioning groove 9 can be rotated to install the positioning pin 10 quickly. In addition, the other positioning pins 10 are locked around the control board 8 to ensure the accuracy of its installation position and to limit the position of the control board 8 to ensure its stability.
[0023] In summary, the purpose of this technical solution is to simplify and facilitate maintenance, solve the problem of not needing to return damaged parts to the factory for repair, implement modular installation of each part, separate the internal battery 7 from the control board 8, facilitate the replacement of each module, and ensure that individual parts can be easily replaced if they fail.
[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.
[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
