Users must perform two separate actions: opening the observation window and initiating cleaning, which is inconvenient. Furthermore, the design of the cleaning component reset mechanism is flawed, affecting cleaning efficiency and device reliability. Therefore, to address these technical problems, a water meter protective casing mechanism that facilitates reading is proposed. Utility Model Content

A sealing cover 2 is detachably connected to the upper side of the shell body 1, which is used to close the upper opening of the shell body 1. An observation opening 5 is provided on the upper side of the sealing cover 2, providing a viewing window for the water meter reading. A glass plate 6 is fixedly connected to the bottom of the observation opening 5, which protects the water meter while ensuring that the reading is clearly visible. A fixing seat 8 is fixedly connected to the upper side of the sealing cover 2, which provides an installation base for the translation mechanism. One side of the fixing seat 8... A guide groove 9 is provided, which provides a sliding track for the slide plate 10. The slide plate 10 is fixedly connected to the outside of the sealing plate 7. The slide plate 10 serves as a transmission connector for the sealing plate 7 and is slidably connected to the inside of the guide groove 9. A connecting plate 11 is fixedly connected to the end of the slide plate 10. The connecting plate 11 serves as a mounting carrier for the toothed plate 12. The toothed plate 12 is fixedly connected to the outside of the connecting plate 11. The toothed plate 12 cooperates with the translation mechanism to achieve transmission. A translation mechanism is installed inside the fixed base 8. The translation mechanism is used to drive the opening and closing movement of the sealing plate 7. A wiping mechanism is installed inside the cover 2. The wiping mechanism is used to automatically clean the inner surface of the glass plate 6.

[0027] The outer shell 1 has pipe openings 3 on both sides. The pipe openings 3 are used to connect water supply pipes. A sealing gasket 4 is fixedly connected to the outside of the pipe openings 3 to ensure the sealing of the pipe connection.

[0028] The sealing plate 7 is installed above the observation opening 5 and is used to protect the observation opening 5 from external contamination.

[0029] The translation mechanism includes a first rotating rod 13, a first gear 14, a second rotating rod 16, and a second gear 17. The first rotating rod 13 serves as the main transmission shaft for manual operation. Both the first rotating rod 13 and the second rotating rod 16 are rotatably connected to the interior of the fixed base 8. The second rotating rod 16 serves as an auxiliary transmission shaft, and the end of the first rotating rod 13 protrudes from the upper surface of the cover 2. The first rotating rod 13 and the second rotating rod 16 are arranged at equal intervals and staggered, which ensures smooth transmission. The first gear 14 is fixedly connected to the outside of the first rotating rod 13. The first gear 14 converts rotational motion into linear motion and meshes with the gear plate 12. The second gear 17 is fixedly connected to the outside of the second rotating rod 16 and is used to synchronize the movement of multiple first gears 14. The second gear 17 meshes with both of its adjacent sets of first gears 14.

[0030] One of the first rotating rods 13 has a screw 15 fixedly connected to its top. The screw 15 provides an operating handle for the user and is rotatably connected to the upper side of the fixed base 8.

[0031] A limiting plate 18 is fixedly connected to the upper side of the outer shell body 1. The limiting plate 18 provides a sliding guide for the sealing plate 7, and one side of the sealing plate 7 is limited and slidably connected to the inner side of the limiting plate 18.

[0032] The wiping mechanism includes a groove 19, a slide bar 20, a tension spring 21, a pull rope 22, and a cleaning strip 23. The groove 19 is opened on both sides of the inside of the cover 2. The groove 19 provides a sliding track for the slide bar 20. The slide bar 20 is slidably connected between two sets of grooves 19. The slide bar 20 serves as the mounting base for the cleaning strip 23. The tension spring 21 is fixedly connected to the inside of the cover 2. The tension spring 21 provides a return spring force, and the end of the tension spring 21 is fixedly connected to one side of the slide bar 20. The pull rope 22 is fixedly connected to the other side of the slide bar 20. The pull rope 22 converts the rotational motion into linear motion, and the end of the pull rope 22 is fixedly connected to the outside of the first rotating rod 13.

[0033] The cleaning strip 23 is fixedly connected to the upper side of the slide strip 20. The cleaning strip 23 is used to wipe the inner surface of the glass plate 6, and the upper surface of the cleaning strip 23 is flush with the lower surface of the glass plate 6.

[0034] The working principle of a water meter protective housing mechanism based on an embodiment is as follows: the user operates a translation mechanism to open or close the observation port. Specifically, rotating the screw 15 will drive the first rotating rod 13 connected to it to rotate, and the first gear 14 fixed on the rotating rod will rotate accordingly. The first gear 14 meshes with the toothed plate 12 fixed on the connecting plate 11. The movement of the toothed plate 12 will drive the connecting plate 11 and the slide plate 10 fixed to the connecting plate 11 to slide along the guide groove 9 on the side of the fixed seat 8. The slide plate 10 is fixed on the sealing plate 7. Therefore, the sealing plate 7 is driven and slides along the upper surface of the housing under the limiting guide of the limiting plate 18, thereby covering or exposing the observation opening 5 and the glass plate 6 below. The second gear 17 on the second rotating rod 16 meshes with the two adjacent first gears 14 to ensure the synchronous rotation of multiple first rotating rods 13 and the smooth movement of the sealing plate 7.

[0035] When the sealing plate 7 is opened, causing the first rotating rod 13 to rotate, the wiping mechanism is driven synchronously. The rotation of the first rotating rod 13 winds the pull rope 22, which pulls the slide bar 20 to overcome the tension of the tension spring 21 and slide in the grooves 19 on both sides inside the sealing plate 2. The cleaning strip 23 fixed on the upper side of the slide bar 20 moves accordingly, and its upper surface is in close contact with the lower surface of the glass plate 6, thereby wiping and cleaning below the glass plate 6. When the operation is reversed, that is, when the sealing plate 7 is closed, the first rotating rod 13 is reversed, and the elastic force of the tension spring 21 will pull the slide bar 20 and the cleaning strip 23 back to their original positions, preparing for the next cleaning. This design realizes that while operating the opening and closing of the sealing plate 7, the water mist on the inner surface of the glass plate 6 is automatically cleaned, ensuring clear readings.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
