[0003] In terms of assembly structure, the ultrasonic water meter includes a measuring pipe at the bottom and a meter head shell at the top, in which battery holders, batteries, digital display circuit boards and other components are installed. In the prior art, the measuring pipe and the meter head shell, as well as the corresponding components inside the meter head shell, are assembled with a large number of screws or welded. Since the ultrasonic water meter itself is relatively small in structure and is basically powered by lithium batteries, when it is necessary to replace batteries or other parts, the overall disassembly and assembly is relatively complicated. In addition, multiple disassembly and assembly may also cause the screws to become stuck or threaded. Utility Model Content

[0004] In view of this, the utility model provides an ultrasonic water meter assembly structure, which aims to ensure that the installation structure is stable while facilitating disassembly, assembly and replacement of parts.

Compared with the traditional threaded installation or welding method, the overall installation method is simpler while ensuring stable installation.

[0008] As a preferred embodiment, the inner bracket is made of plastic material. With the above structure, the inner bracket is cheap, the plastic part is more elastic, and the clamping is more convenient.

[0009] Preferably, there are three support rods, each of which includes a support section and a positioning section located at the upper part of the support section. The positioning section is thinner than the support section so that the upper end of the support section forms a support surface.

[0011] Preferably, the clamp ring is evenly distributed with elastic sheets extending inwards around the circumference, and the elastic sheets are clamped inside the clamping groove. The above structure can ensure that the inner bracket can be fixedly installed inside the meter head housing, and the inner bracket, the meter head housing and the detection pipeline are pulled together.

[0012] Preferably, the elastic sheet is tilted to form a hollow area below the inner bracket corresponding to the clamping ring, and a nut screwed on the connecting column is installed in the hollow area. With the above structure, the inner bracket and the connecting column can form a barb structure, which is convenient for installing the inner bracket and can prevent it from falling off easily. The hollow area makes the entire assembly structure more compact.

[0013] As a preferred embodiment, four upwardly extending limit posts are arranged around the battery slot, and the four limit posts are symmetrically distributed in pairs.

[0015] Preferably, an upper end cover is provided on the top of the mounting ring, and the upper end cover can be buckled on the top of the meter head housing and fix the mounting ring between the meter head housing and the upper end cover. The above structure can ensure that the perspective glass can be fixedly installed.

[0023] The utility model is further described below in conjunction with embodiments and drawings.

[0024] like Figures 1 to 3 As shown, an ultrasonic water meter assembly structure includes a meter head housing 1 and a detection pipe 2 fixedly connected to the bottom of the meter head housing 1, wherein the detection pipe 2 is used to connect between tap water pipes, and detect the water flow through symmetrically arranged ultrasonic transducers, and the top of the detection pipe has two connecting columns 2a extending upward into the inside of the meter head housing 1, and the connecting columns 2a are used to pass the signal transmission line of the ultrasonic transducer. In this embodiment, nuts 5 are screwed on the connecting columns 2a, which are used to fix the detection pipe 2 at the bottom of the meter head housing 1. In addition, both groups of connecting columns 2a are provided with a card slot 2a1, and an inner bracket 3 is provided inside the meter head housing 1, and a clamping ring 3a is provided at the position of the inner bracket 3 corresponding to the connecting column 2a. When the bottom of the inner bracket 3 is supported on the bottom of the meter head housing 1, the clamping ring 3a can be clamped on the card slot 2a1, so that the inner bracket 3, the meter head housing 1 and the detection pipe 2 are pulled together as a whole, and the stability of the installation of the inner bracket 3 is ensured.

[0025] A battery slot 3b is provided on the inner bracket 3, and the battery slot 3b can be used to fix and install the battery 9. The inner bracket 3 is also evenly arranged with support rods 3c and card columns 3d extending upward. The upper ends of the support rods 3c and the card columns 3d are detachably installed with a digital display circuit board 4, and the digital display circuit board 4 is located above the battery slot 3b.

[0026] With such a design, by setting up the inner bracket 3, by means of a clamping method, not only the inner bracket 3, the meter head housing 1 and the detection pipe 2 are pulled together as a whole, but also the digital display circuit board 4 and the battery 9 are fixedly installed. Compared with the traditional method of fixing with screws or welding, the installation method is simpler.

[0027] Specifically, Figure 3 and Figure 4 As shown, the support rod 3c includes a support section 3c1 and a positioning section 3c2 located at the upper end of the support section 3c1, wherein the positioning section 3c2 is thinner than the support section 3c1, so that the upper end of the support section 3c1 forms a support surface, and the digital display circuit board 4 is mounted on the positioning section 3c2 and abuts against the support surface of the support section 3c1, so that the digital display circuit board 4 can be stably installed on the support rod 3c. In this embodiment, three support rods 3c are evenly distributed on the inner bracket 3, and the three evenly distributed support rods 3b can ensure that the digital display circuit board 4 is installed stably without shaking, and the digital display circuit board 4 can be limited to ensure that the digital display circuit board 4 is installed without deviation.

[0028] Furthermore, a tongue 3d1 protruding inward is formed on the upper end of the clamping column 3d, and the digital display circuit board 4 is restricted on the lower side of the tongue 3d1. A guiding slope 3d2 is also provided on the inner side of the upper end of the tongue 3d1, and the guiding slope 3d2 can facilitate the installation of the digital display circuit board 4. In this embodiment, two clamping columns 3d are symmetrically distributed on the inner bracket 3, and the symmetrically distributed clamping columns 3d can ensure that the digital display circuit board 4 can be fixedly buckled.

[0029] In this embodiment, in addition to three support rods 3c evenly distributed on the inner bracket 3, four, five, or even more support rods 3c can also be evenly distributed. Similarly, in addition to two symmetrically distributed clamping columns 3d on the inner bracket 3, three, four, or even more clamping columns 3d can also be evenly distributed on the inner bracket 3 to ensure that the digital display circuit board 4 can be fixedly installed inside the meter head housing 1.

[0030] For example Figure 3 and Figure 4As shown, the snap ring 3a is evenly distributed with elastic pieces 3a1 extending inwards in the circumferential direction, and the elastic pieces 3a1 are clamped in the clamping groove 2a1. In this embodiment, the elastic pieces 3a1 are tilted so that a hollow area is formed under the inner bracket 3 corresponding to the snap ring 3a, and the nut 5 is screwed in the hollow area. The tilted elastic pieces 3a1 form a barb structure between the snap ring 3a and the support column 2a, which facilitates the installation of the inner bracket 3 and effectively prevents the inner bracket 3 from loosening and falling off.

[0031] like Figure 3 As shown, four upwardly extending limit posts 3d1 are arranged around the battery slot 3b, and the four limit posts 3d1 are symmetrically distributed in pairs. Such a design can ensure that the battery 9 is fixedly installed inside the battery slot 3b.

[0032] Further, such as Figure 5 As shown, a mounting ring 6 is installed on the top of the meter head housing 1, and limit baffles 6a are evenly distributed around the mounting ring 6. A transparent glass 7 is installed in the limit baffles 6a. The evenly distributed limit baffles 6a can ensure that the transparent glass 7 is installed without shaking. In addition to facilitating the observation of readings, the transparent glass 7 can also effectively prevent impurities from entering the interior of the meter head housing 1 and affecting the accuracy of the water meter measurement data.

[0033] For example Figure 1 As shown, an upper end cover 8 is also provided on the top of the mounting ring 6, and the upper end cover 8 can be buckled on the top of the meter head housing 1, and the mounting ring 6 is fixedly installed between the meter head housing 1 and the upper end cover 8, so that the water meter as a whole is a closed structure, thereby ensuring the stability of the overall installation structure of the water meter.

[0034] In this embodiment, the inner bracket 3 and the mounting ring 6 are both made of plastic, and the clamping ring 3a, battery clamping slot 3b, support rod 3c, clamping column 3d and limit baffle 6a are all integrally formed by injection molding. This is not only low-cost, but also the plastic material has good elasticity, making it easier to install or replace parts.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make a variety of similar expressions without violating the purpose and claims of the present invention, and such changes fall within the scope of protection of the present invention.
