DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a water meter with convenient disassembly and assembly, including an outer housing 1. Two card holes 2 are opened inside the outer housing 1. A water meter body 3 is slidably connected to the inner side of the outer housing 1. Two cavities 4 are opened inside the water meter body 3. A card block 5 is slidably connected to the inside of the cavity 4. One end of the card block 5 is fixedly connected to a spring 6. Two notches 7 are opened on the outer side of the outer housing 1. Two limiting blocks 9 are fixedly connected to the outer side of the outer housing 1. A protective ring 10 is rotatably connected to the outer side of the outer housing 1. Two limiting grooves 11 are opened on the inner side of the protective ring 10. Two through holes 12 are opened inside the protective ring 10. A sealing component is arranged inside the outer housing 1. When it is necessary to disassemble the water meter, pull the protective cover 17 upward, so that the protective cover 17 is pulled out from the outer side of the outer housing 1. Then rotate the protective ring 10 to expose the card holes 2 behind the two through holes 12. Then use a finger or a tool to pass through the through holes 12 and the card holes 2 to push the card block 5, so that the card block 5 retracts into the inside of the cavity 4. The notch 7 is convenient for the user to hold the top layer of the water meter body 3 with the hand, and then lift the water meter body 3 upward, so that the water meter can be easily disassembled.

[0024] Refer to Figures 2 - 4, the sealing assembly includes a first sealing groove 15 which is opened on the inner side of the outer housing 1. An annular groove 13 is opened on the outer side of the water meter body 3. A first sealing ring 14 is sleeved on the outer side of the annular groove 13. The outer side of the first sealing ring 14 is attached to the inner side of the first sealing groove 15. An annular groove 16 is opened on the outer side of the outer housing 1. A protective cover 17 is slidably connected to the outer side of the outer housing 1. A second sealing groove 8 is opened on the inner side of the protective cover 17. A second sealing ring 18 is sleeved on the outer side of the annular groove 16. The outer side of the second sealing ring 18 is attached to the inner side of the second sealing groove 8. When the water meter is reassembled, first put a new first sealing ring 14 on the outside of the annular groove 13 to improve the sealing performance. Then press the water meter body 3 into the inner part of the outer housing 1. The inclined surface of the clamping block 5 contacts the edge of the outer housing 1 and shrinks. Then rotate the water meter body 3, which will cause the positions of the two clamping blocks 5 to rotate. When the clamping block 5 moves to the position of the clamping hole 2, the cavity 4 will eject the clamping block 5, and the clamping block 5 will be stuck inside the clamping hole 2. Then put a new second sealing ring 18 on the outside of the annular groove 16 and press the protective cover 17 on the top of the outer housing 1. When the second sealing ring 18 is engaged with the inner side of the second sealing groove 8, the installation is completed. And the two-layer sealing structure can make the water meter have better sealing performance.

[0025] Refer to Figures 1 - 3 , one end of the spring 6 is fixedly connected to the inner wall of the cavity 4, the other end of the clamping block 5 is engaged inside the clamping hole 2, the outer side of the limiting block 9 slides inside the limiting groove 11, the through hole 12 is communicated with the clamping hole 2, the top of the protective cover 17 is made of glass material. The clamping block 5 being stuck inside the clamping hole 2 can assemble the water meter body 3 and the outer housing 1 together. The glass material at the top of the protective cover 17 can facilitate people to observe the water meter reading.

[0026] Working principle: When the water meter needs to be disassembled, the protective cover 17 can be lifted upwards first to separate the protective cover 17 from the outside of the outer housing 1. Then rotate the protective ring 10 to make the two through holes 12 communicate with the clamping hole 2. Then use a finger to pass through the through hole 12 and the clamping hole 2 to squeeze the clamping block 5 to make the clamping block 5 retract into the cavity 4. Then use a finger to hold the position of the notch 7 and lift the water meter body 3 upwards, so that the water meter can be easily disassembled. When reassembling, a new first sealing ring 14 can be put on the outside of the annular groove 13, and then the water meter body 3 is pressed into the inner part of the outer housing 1. Then rotate the water meter body 3. When the clamping block 5 moves to the position of the clamping hole 2, the cavity 4 will eject the clamping block 5, and the clamping block 5 will be stuck inside the clamping hole 2. Then put a new second sealing ring 18 on the outside of the annular groove 16 and press the protective cover 17 on the top of the outer housing 1. When the second sealing ring 18 is engaged with the inner side of the second sealing groove 8, the installation is completed. And the two-layer sealing structure can make the water meter have better sealing performance.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
