[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0025] Reference Figures 1-3 A novel stainless steel ultrasonic water meter shell, comprising a shell main body 1, two installation openings 2 are formed on the top of the shell main body 1, the top of the two installation openings 2 is on the same horizontal plane, and a transducer 3 is positioned and installed in the two installation openings 2; further comprising a fixing frame 4 installed on the top of the shell main body 1, a through opening 41 corresponding to the installation hole is formed on the fixing frame 4, and a sealing ring 6 is arranged between the through opening 41 and / or the installation opening 2 and the transducer 3; the top of the fixing frame 4 is further provided with a pressing cap 5 for pressing and fixing the transducer 3.
[0026] It can be understood that the installation opening 2 is used for positioning and installing the transducer 3, and the top of the two installation openings 2 is on the same horizontal plane to ensure the accuracy of the installation position of the transducer 3. In general, if machining is used, the height of the installation opening 2 around is not the same, and subsequent continuous correction is required, which is complicated to operate. Here, the installation opening 2 formed by inside-outward turning on the shell main body 1 is interpenetrating, and the top is flush. Since there are two installation openings 2, the fixing frame 4 is provided with two, and the two fixing frames 4 can be integrally connected or independently disconnected. The contact installation of the fixing frame 4 can adopt welding or bonding, but here the welding is preferred. The sealing ring 6 is a component for enhancing the tightness between the transducer 3 and the through opening 41 and the installation opening 2, preventing water leakage, which can be rubber or silicone, but is not limited thereto. The pressing cap 5 is a component for pressing and fixing the transducer 3, which can be a cylindrical cap structure or a bent plate structure with a groove, but is not limited thereto. The pressing cap 5 needs to be connected to the fixing frame 4, which can adopt welding or bolt connection, but is not limited thereto.
[0027] In this way, during installation, the transducer 3 is inserted into the installation opening 2 for positioning, and then the pressing cap 5 is pressed on the transducer 3, and the sealing ring 6 is pressed and fixed on the transducer 3. Here, compared with the prior art, the transducer 3 cap is removed, and the through opening 41 and / or the installation opening 2 is directly used as the sealing ring 6 and the pressing support surface of the transducer 3.
[0028] In some embodiments, reference Figures 2-3The top of the mounting port 2 is outwardly flanged to form a protruding ring port 21, and the through port 41 is sleeved on the ring port 21. Further, the top of the ring port 21 is inwardly recessed to form a recess 22 for mounting the sealing ring 6. It can be understood that the recess 22 on the protruding ring port 21 is directly used as the mounting position of the sealing ring 6, and the through port 41 on the fixing frame 4 does not participate in the cooperation with the sealing ring 6, but only serves as the fixed base of the pressing cap 5.
[0029] In some embodiments, referring to Figures 4-5 The top of the mounting port 2 is a flat structure, the through port 41 is concentrically arranged with the mounting port 2, and the diameter of the through port 41 is greater than the diameter of the mounting port 2 to form an inner ring for mounting the sealing ring 6. It can be understood that the flat structure is smooth at the top without protruding structure. After the fixing frame 4 is directly welded on the watch case body, the inner ring is formed by the inner ring 42 of the through port 41, the top of the watch case body, and the mounting port 2. Here, the through port 41 serves as a limiting cooperation with the sealing ring 6.
[0030] In some embodiments, the pressing cap 5 includes a ring sleeve 51 sleeved on the transducer 3 and abutting against the top of the fixing frame 4, and a pressing plate 52 located at the top of the ring sleeve 51 and pressing on the transducer 3. Here, the ring sleeve 51 serves to protect the transducer 3 and connect the fixing frame 4. The ring sleeve 51 is preferably made of plastic material, which can save costs. The pressing plate 52 and the ring sleeve 51 can be integrally formed, and can be subsequently bonded, but are not limited thereto. Here, the pressing plate 52 and the ring sleeve 51 are integrally arranged, so that the transducer 3 can be pressed and fixed when the ring sleeve 51 is installed.
[0031] Further, one end of the ring sleeve 51 close to the fixing frame 4 is outwardly provided with an extension edge 53, and at least two fixing holes are correspondingly formed in the extension edge 53 and the fixing frame 4. Here, the extension edge 53 can be a ring structure, or a plurality of connecting pieces can be arranged at intervals, etc. The pressing cap 5 and the fixing frame 4 can be locked together by screwing the bolts into the fixing holes.
[0032] The above description is only a preferred embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacements or changes within the technical range disclosed by the present application according to the technical scheme and improvement concept of the present application, which should be covered within the protection scope of the present application.
