[0002] A water meter is an instrument for measuring water flow, mostly for measuring the cumulative water flow. Generally, it is divided into two categories: volumetric water meters and velocity water meters. During the production and manufacturing of water meters, it is necessary to detect their sealing performance. The sealing detection device for water meter processing is a device used to detect the sealing performance of water meter products.

[0003] In a sealing detection device for water meter processing disclosed in the Chinese utility model patent application publication specification CN219064780U, a plurality of connecting mechanisms are provided to seal the water meter, and a water supply mechanism is provided to fill water into the water meter. The provided sealing mechanism can push the adjacent connecting mechanisms to move along the positioning plate, so that the adjacent connecting mechanisms can seal the water meter, ensuring that multiple water meters can be sealed by the connecting mechanisms. Such a setting can perform sealing detection on multiple water meters at one time. However, the sealing detection device for water meter processing has low flexibility in use. For water meters with different calibers, the connection effect between the device and the water meter may be poor, thus affecting the subsequent sealing detection effect of the water meter.

By closing the electric valve 702, water or gas can be input into the interior of the water meter main body 9 through the hard pipe 7 on the other side, so as to carry out the sealing monitoring work of the water meter main body 9.

[0022] The sealing mechanism 8 includes an insertion pipe 801 fixedly connected to one side of the hard pipe 7, an inflation port 802 is installed on one side of the top end of the insertion pipe 801, an inflatable airbag 803 is fixedly connected to one side of the inflation port 802, a rubber pad 804 is fixedly connected to the outer side of one side of the insertion pipe 801 and is attached to the inflatable airbag 803. When the inflation port 802 is opened, an external inflator can inflate the interior of the inflatable airbag 803. At this time, the inflatable airbag 803 inflates and expands, which can push the rubber pad 804 to tightly adhere to the inner wall of the water meter main body 9, completing the sealed connection between the water meter main body 9 and the water meter main body 9.

[0023] Example 2

[0024] The main difference from Example 1 is as follows:

[0025] A sealing detection device for water meter processing. In the adjusting mechanism 4, there is a fixed rod 401 fixedly connected to one side of the connecting block 301. The top of the fixed rod 401 is evenly provided with positioning holes 402 at equal distances. A connecting seat 5 is slidably connected to the outside of the fixed rod 401. A pull rod 501 is slidably connected to the inside of the top of the connecting seat 5. The bottom end of the pull rod 501 is fixedly connected with a movable block 502. The top end of the movable block 502 is fixedly connected with a spring 503. The middle position of the bottom end of the movable block 502 is fixedly connected with a positioning rod 504 inserted into the positioning hole 402. When the pull rod 501 is pulled, the pull rod 501 can squeeze the spring 503 through the movable block 502. At this time, the movable block 502 can drive the positioning rod 504 to move. When the pull rod 501 is released, due to the reaction force of the spring 503 being squeezed, the positioning rod 504 can be pushed by the movable block 502 to reset. When the positioning rod 504 is inserted into the positioning holes 402 at different positions on the fixed rod 401, the position of the connecting seat 5 on the fixed rod 401 can be fixed.

[0026] In the connecting mechanism 6, there is a connecting rod 601 fixedly connected to the middle position of the bottom end of the connecting seat 5. The bottom end of the connecting rod 601 is fixedly connected with a limiting ring 602. Two sides inside the limiting ring 602 are fixedly connected with positioning blocks 603. Two sides of the outside of the hard tube 7 are provided with positioning grooves 701 inserted with the positioning blocks 603. When the connecting seat 5 moves, the hard tube 7 can be driven to move through the connecting rod 601 and the limiting ring 602. At this time, the two groups of hard tubes 7 can be connected to water meter bodies 9 of different specifications. At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] When the embodiment of the present application is in use: By pulling the pull rod 501 on the connecting seat 5, the pull rod 501 can drive the positioning rod 504 to be pulled out from the positioning hole 402 on the fixed rod 401 through the movable block 502. At this time, the connecting seat 5 can move on the adjusting mechanism 4 and drive the lower hard pipe 7 to move through the connecting mechanism 6. Then, the two groups of hard pipes 7 at the bottom end of the fixed rod 401 can be respectively inserted into both sides of the water meter main body 9. At this time, by opening the inflation ports 802 on the two groups of hard pipes 7, an external inflator can inflate the inflation airbag 803 in the sealing mechanism 8. At this time, the inflated inflation airbag 803 can push the rubber pad 804 to tightly adhere to the inner wall of the water meter main body 9, completing the connection between the hard pipe 7 and the water meter main body 9. At this time, by closing the electric valve 702 on one side of the hard pipe 7 and inputting the water liquid into the interior of the water meter main body 9 from the other hard pipe 7, the sealing performance of the water meter main body 9 can be detected, or by driving the water meter main body 9 to immerse in the water liquid inside the water tank 2 through the electric push rod 3 and detecting the gas conveyed into the interior of the water meter main body 9.
