[0028] This embodiment provides a water meter housing structure with a detachable active battery 9 . Example 2

[0029] like Figure 3~Figure 5 As shown, on the basis of Example 1, a sliding lock structure 4 is further proposed, which includes a connecting seat 41 fixedly connected to the outer surface of the lower shell 2, and side protrusions 42 are spaced apart on the outer surfaces of both sides of the connecting seat 41, an end protrusion plate 43 is fixedly connected to one end of the connecting seat 41, a locking strip 45 is fixedly connected to the lower end of the upper shell 3, side connecting blocks 46 are fixedly connected to the inner sides of the locking strip 45, and an end connecting block 47 is fixedly connected to one end of the inner side of the locking strip 45.

[0030] The snap-fitting strip 45 is fixed to the upper shell 3 by ultrasonic welding, a connecting hole 44 is provided on the outer surface of the lower end of the upper shell 3, a positioning hole 48 is provided at the lower end of the upper shell 3 corresponding to the upper end of the connecting hole 44, and a positioning column 49 is fixedly connected to the upper end of the snap-fitting strip 45; the number of side protrusions 42 is several groups, which are respectively distributed on both sides of the outer surface of the connecting seat 41 at intervals, and the spacing between two adjacent groups of side protrusions 42 on the same side is equal; the number of side connecting blocks 46 on the snap-fitting strip 45 is equal to the side protrusions 42, and the positions of the two correspond one by one, the spacing between two adjacent groups of side connecting blocks 46 on the same side is equal to the spacing between two adjacent groups of side protrusions 42 on the same side, and the spacing between two adjacent groups of side connecting blocks 46 is greater than the length of the side connecting blocks 46 in the spacing direction.

[0031] The end convex plate 43 matches the concave groove body formed between the lower shell 2 and the connecting seat 41, and the end connecting block 47 is matched, and the sliding connection between the upper shell 3 and the lower shell 2 is realized by passing the side connecting block 46 through the snap-fit ​​strip 45 and moving; the movable battery 9 matches the battery slot 8, and the lower lead seal 6 is fixedly connected to the outer surface of one end of the lower shell 2 near the corner, and the inner opening of the upper shell 3 matches the connecting seat 41; the positioning column 49 matches the positioning hole 48, and the number of both is several groups. The positioning hole 48 is used to limit the position of the positioning column 49 to realize the precise positioning welding of the snap-fit ​​strip 45 and the upper shell 3, and the snap-fit ​​strip 45 matches the connecting hole 44.

[0032] In this embodiment, when the upper shell 3 needs to be installed on the lower shell 2, the user can grab the upper shell 3 and make the position of the side connecting block 46 on the snap-fit ​​strip 45 correspond to the gap of the side protrusion 42, and press downward so that the upper end of the side connecting block 46 is just flush with the lower end of the side protrusion 42, and then slide the upper shell 3 to make the end connecting block 47 move toward the groove formed by the end protrusion plate 43, the connecting seat 41 and the lower shell 2 until the end connecting block 47 is just embedded in the groove. At this time, each group of side connecting blocks 46 is just located directly below each group of side protrusions 42, and the position of the upper lead seal 7 just corresponds to the position of the lower lead seal 6. Then, the connection between the upper lead seal 7 and the lower lead seal 6 can be established by screws. The connection between the entire upper shell 3 and the lower shell 2 is fixed by only one screw, which simplifies the operation. During the installation process, the workload of installing screws is reduced, making the connection of the outer shell structure simpler and faster. During use, when it is necessary to disassemble the upper shell 3 to replace the active battery 9, the user can loosen the screws with a screwdriver, and then grab the upper shell 3 and slide it to one side to separate the side connecting block 46 from the side protrusion 42. At this time, the inner wall of the upper shell 3 just contacts the outer surface of one end of the connecting seat 41, and then the upper shell 3 is taken out vertically upward, and then the active battery 9 is disassembled and replaced. At the same time, the easy-to-open method can also facilitate the inspection and maintenance of the components inside the upper shell 3. The present invention not only simplifies the installation of the water meter outer shell and simplifies the production workload through the side-sliding lock, but also facilitates the replacement of the active battery 9 and the inspection and replacement of individual components inside the water meter.

[0033] When the mobile battery 9 needs to be replaced, the upper shell 3 can be conveniently slid open from the lower shell 2 to conveniently replace the mobile battery 9, which is convenient for the overall installation of the shell structure, saves space, and is conducive to miniaturization design.

[0034] It should be noted that the way the flip cover 5 is opened is used to protect the water meter display interface.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
