Abstract
Description
Technical Field
[0001] This utility model relates to the field of water meter antifreeze technology, and in particular to a wet water meter movement with antifreeze function. Background Technology
[0002] Water meters are an essential device in every household nowadays. The key component in a water meter is the water meter movement, which is usually a wet-type water meter movement that is submerged in water during use.
[0003] In conventional wet-type water meter movements, freezing temperatures in winter can cause damage to the top glass of the meter due to the expansion of the frozen water. Therefore, achieving freeze protection for wet-type water meter movements has become a crucial technical challenge. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects of the existing technology and provide a wet water meter movement with antifreeze function.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A wet water meter movement with antifreeze function includes a metering assembly and a counter assembly fixed by interference fit. The counter assembly includes a gear box. The gear box contains an upper clamping plate, a lower clamping plate, and a gear set. The upper and lower clamping plates are fixed to the gear box by bolts. The gear set is located in the gear box and consists of multiple meshing gears. The gear set is interference-fitted with a pointer. The upper clamping plate is a simulated fully liquid-sealed clamping plate with a countersunk hole. The pointer is located in the countersunk hole. Both the upper and lower clamping plates have multiple positioning holes. The gear set is positioned and connected through the positioning holes at the upper and lower ends. The upper and lower clamping plates also have positioning grooves. A digit wheel window is positioned and installed in the positioning groove.
[0007] Furthermore, the metering assembly includes a filter screen, an impeller box, and an impeller; the filter screen and the impeller box are connected by an interference fit; the impeller is disposed inside the impeller box; the top of the impeller passes through the impeller box and the impeller housing and meshes with the gear set; the lower end of the gear box and the upper end of the impeller box are fixed by an interference fit.
[0008] Furthermore, the bottom of the filter screen is provided with a first mounting groove; the first mounting groove is filled with a first sponge filler.
[0009] Furthermore, the upper clamping plate is provided with a plurality of second mounting slots; the lower clamping plate is provided with a plurality of third mounting slots; and the second mounting slots and the third mounting slots are both filled with a second sponge filler.
[0010] Furthermore, a third sponge filler is provided between the lower clamping plate and the gear box.
[0011] Furthermore, the water meter movement is mounted on the meter casing; a meter cover is mounted on the water meter movement; a meter glass is disposed between the top of the water meter movement and the meter cover; the meter glass is pressed against the upper clamping plate.
[0012] Furthermore, a waterproof gasket is provided between the water meter movement and the meter cover.
[0013] Compared with the prior art, the present invention has the following advantages:
[0014] (1) This utility model uses a simulated liquid-sealed upper clamping plate with a countersunk hole for installing the pointer. When the water meter movement is installed, the upper panel of the upper clamping plate will be tightly attached to the glass. The water will stay in the countersunk hole where the pointer is located and will not spread to the bottom of the entire glass. In this way, the contact area between the water and the glass is greatly reduced. When freezing causes the water pressure to rise, it can alleviate the pressure on the glass to a certain extent, thereby achieving the purpose of antifreeze, preventing damage to the glass, and reducing maintenance costs.
[0015] (2) The present invention uses the design of the first mounting groove, the second mounting groove and the third mounting groove, and sets sponge filling material in each mounting groove. The compressible sponge further offsets the pressure, improves the antifreeze effect, and further reduces the risk of damage to the meter glass and the water meter movement.

[0028] Example
[0029] like Figs. 1-4 As shown, a wet water meter movement with antifreeze function is disclosed. The water meter movement is mounted on a meter case 18. A meter cover 19 is mounted on the water meter movement. A meter glass 20 is disposed between the top of the water meter movement and the meter cover 19. A waterproof gasket 21 is also disposed between the water meter movement and the meter cover 19 for waterproof sealing. The water meter movement includes a metering assembly and a counter assembly fixed by interference fit. The counter assembly includes a gear box 3. An upper clamping plate 2, a lower clamping plate 4, and a gear set 10 are disposed inside the gear box 3. The meter glass 20 is pressed on top of the upper clamping plate 2. The upper clamping plate 2 and the lower clamping plate 4 are fixed inside the gear box 3 by bolts. The gear set 10 is disposed inside the gear box 3 and is composed of multiple meshing gears. A pointer 11 is interference-fitted to the gear set 10. The upper clamping plate 2 is a simulated fully liquid-sealed clamping plate with a countersunk hole 12. The pointer 11 is disposed inside the countersunk hole 12, so that when the water meter movement is installed, the upper clamping plate 2... The upper panel will be tightly pressed against the dial glass 20, and the water will remain in the countersunk hole 12 where the pointer 11 is located, preventing it from spreading to the bottom of the dial glass 20. This greatly reduces the contact area between the water and the dial glass 20. When freezing causes the water pressure to rise, it can alleviate the pressure on the dial glass 20 to a certain extent, thereby achieving the purpose of antifreeze, preventing damage to the dial glass, and reducing maintenance costs. The upper clamping plate 2 and the lower clamping plate 4 are both provided with multiple positioning holes 13. The gear set 10 is positioned and connected through the positioning holes 13 at the upper and lower ends. The upper clamping plate 2 and the lower clamping plate 4 are also provided with positioning grooves 22. The dial wheel window 1 is positioned and installed in the positioning grooves 22.
[0030] The metering assembly includes a filter screen 6, an impeller box 5, and an impeller 8. The filter screen 6 and the impeller box 5 are connected by an interference fit. The impeller 8 is disposed inside the impeller box 5. The top of the impeller 8 passes through the impeller box 5 and the gear box 3 and meshes with the gear set 10. The lower end of the gear box 3 and the upper end of the impeller box 5 are fixed by an interference fit. The bottom of the filter screen 6 is provided with a first mounting groove 14. The first mounting groove 14 is filled with a first sponge filler 7. The upper clamping plate 2 is provided with a plurality of second mounting grooves 15. The lower clamping plate 4 is provided with a plurality of third mounting grooves 16. The second mounting grooves 15 and the third mounting grooves 16 are both filled with a second sponge filler 17. The space between the lower clamping plate 4 and the gear box 3 is filled with a third sponge filler 9. The sponge filler relieves the pressure on each component, improves the antifreeze effect, and further reduces the risk of damage to the meter glass 20 and the water meter movement.
[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort.
