In this way, the installation of the volumetric correction instrument body can be completed.

[0016] 2. The volumetric correction instrument body is powered by a battery on the back. When the battery power is insufficient, the battery needs to be replaced. At this time, the volumetric correction instrument body can be pressed downwards by hand. The volumetric correction instrument body presses the movable plate and the first spring downwards through the connecting column, and the inserting rod moves down along the vertical groove to the horizontal groove. Then, rotate the volumetric correction instrument body and the connecting column. At the same time, the inserting rod rotates along the horizontal groove until it moves to the lower part of the vertical groove on the other side of the horizontal groove. Release the volumetric correction instrument body, and the movable plate is pushed by the first spring, and then the inserting rod is pushed into the vertical groove again. At this time, the position of the volumetric correction instrument body is fixed again, and the volumetric correction instrument body is rotated by 90 degrees. In this way, it is convenient to expose the battery installation position on the back of the volumetric correction instrument body, and the battery can be replaced from the side. In this way, it is not necessary to disassemble the volumetric correction instrument body to replace the battery located on the back of the volumetric correction instrument body, which is convenient for use.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Such as Figure 1-7As shown in the figure, the present invention provides a technical solution: a comprehensive detection device for a volume corrector, including a flowmeter body 1 and a volume corrector body 2. The volume corrector body 2 is detachably installed on the middle of the top of the flowmeter body 1 through a connection component 3. The connection component 3 includes a connection block 31 fixedly connected to the top of the flowmeter body 1. A connection sleeve 33 is connected to the connection block 31. A first spring 39 is fixedly connected to the middle inside the connection sleeve 33. The top end of the first spring 39 is fixedly connected to a movable plate 38. The side of the movable plate 38 is in contact with the inside of the connection sleeve 33 and can move up and down along the connection sleeve 33. A connection column 34 is installed at the middle position of the bottom end of the volume corrector body 2. The connection column 34 is inserted into the inside of the connection sleeve 33, and the bottom end of the connection column 34 is in contact with the upper end surface of the movable plate 38. Horizontal grooves 35 are respectively opened on both sides of the middle of the connection sleeve 33. Vertical grooves 37 are respectively opened at both ends of the horizontal groove 35. The bottom end of the vertical groove 37 is flush with the horizontal groove 35. The top of the vertical groove 37 is arranged above the horizontal groove 35. An installation component 4 is arranged inside the connection column 34. The connection column 34 is installed in the connection sleeve 33 through the installation component 4. The connection component 3 includes two activity cavities 413 which are symmetrically arranged inside the connection column 34. Slide cavities 45 are respectively opened on the upper parts of the opposite sides of the two activity cavities 413. A through hole one 43 is opened on the side of the slide cavity 45 away from the activity cavity 413. Through holes two 49 are respectively opened on the lower parts of the opposite sides of the two activity cavities 413. Vertical plates 48 are slidably installed in the two activity cavities 413. On the middle of the upper parts of the opposite sides of the two vertical plates 48, a connecting rod 47 is fixedly connected. One end of the connecting rod 47 away from the vertical plate 48 is fixedly connected with a slider 46. The side wall of the slider 46 is in contact with the inner wall of the slide cavity 45 and slides along the slide cavity 45. A moving rod 41 is movably installed in the through hole one 43. One end of the moving rod 41 penetrates and extends to the outside of the connection column 34. On the middle of the lower parts of the opposite sides of the two vertical plates 48, a plugging rod 410 is fixedly connected. One end of the plugging rod 410 away from the vertical plate 48 penetrates and extends to the outside of the connection column 34. The plugging rod 410 is adapted to the horizontal groove 35 and the vertical groove 37. When the connection column 34 is inserted into the inside of the connection sleeve 33, the end of the plugging rod 410 located outside the connection column 34 is inserted into the vertical groove 37. When in use, when it is necessary to install the volume corrector body 2 on the flowmeter body 1, first, the connection column 34 is fixedly connected to the lower part of the volume corrector body 2 through bolts and a second connection flange 36. Then, by simultaneously pressing the two moving rods 41 towards the middle, the moving rods 41 move along the through hole one 43 and squeeze the sliders 46 in the slide cavities 45. While the sliders 46 move inwards, they drive the vertical plates 48 to move through the connecting rods 47. While the vertical plates 48 move, they drive the plugging rods 410 to move, so that the ends of the plugging rods 410 are retracted into the through holes two 49. At this time, the connection column 410 can be inserted into the connection sleeve 33 from the top. The connection column 34 moves down along the inner cavity of the connection sleeve 33 and presses the movable plate 38 downwards. The movable plate 38 presses the first spring 39, causing the first spring 39 to be compressed.When the insertion rod 34 moves to the position aligned with the vertical groove 37, release the moving rod 41. Then, under the pushing action of the second spring 412, the vertical plate 48 is reset, and then the end of the insertion rod 410 is pushed out of the outer side of the second through hole 49 again and inserted into the vertical groove 37. At the same time, under the elastic force of the first spring 39, the movable plate 38 always presses the bottom end of the connecting column 34, so that the insertion rod 410 is stably inserted into the vertical groove 37, and thus the installation of the volumetric corrector body 2 can be completed. In addition, the volumetric corrector body 2 is powered by the battery 5 on the back. When the battery 5 runs out of power, the battery 5 needs to be replaced. At this time, the volumetric corrector body 2 can be pressed downward by hand. The volumetric corrector body 2 squeezes the movable plate 38 and the first spring 39 downward through the connecting column 34, and the insertion rod 410 moves downward along the vertical groove 37 into the horizontal groove 35. Then, rotate the volumetric corrector body 2 and the connecting column 34. At the same time, the insertion rod 410 rotates along the horizontal groove 35 until it moves to the lower part of the vertical groove 37 on the other side of the horizontal groove 35. Release the volumetric corrector body 2, and push the movable plate 38 through the first spring 39, and then push the insertion rod 410 into the vertical groove 37 again. At this time, the position of the volumetric corrector body 2 is fixed again, and the volumetric corrector body 2 is rotated by 90 degrees. This is convenient for exposing the installation position of the battery 5 on the back of the volumetric corrector body 2, and the battery 5 can be replaced from the side. In this way, it is not necessary to disassemble the volumetric corrector body 2 to replace the battery 5 located on the back of the volumetric corrector body 2, which is convenient for use.

[0027] Further, a second spring 412 for resetting the vertical plate 48 is installed inside the movable cavity 413. A telescopic rod 411 is arranged inside the movable cavity 413. The telescopic rod 411 is horizontally arranged. One end of the telescopic rod 411 is fixedly connected to the inner wall of the movable cavity 413, and the other end of the telescopic rod 411 is fixedly connected to the side of the vertical plate 48 away from the sliding cavity 45. The second spring 412 is sleeved on the telescopic rod 411. By setting the second spring 412, the vertical plate 48 can be reset, and then the end of the insertion rod 410 is pushed out of the outer side of the second through hole 49 again and inserted into the vertical groove 37, which is convenient for installing and fixing the connecting column 34. By setting the telescopic rod 411 to play a guiding role, the displacement of the vertical plate 48 is more stable.

[0028] Further, an internal thread 44 is arranged at one end of the first through hole 43 adjacent to the sliding cavity 45. An external thread 42 is arranged at one end of the moving rod 41 close to the slider 46. The external thread 42 is engaged with the internal thread 44. Initially, the end of the moving rod 41 with the external thread 42 is located in the sliding cavity 45. After the insertion rod 410 is inserted into the vertical groove 37, by pulling the moving rod 41 outwards and rotating the moving rod 41, the external thread 42 is engaged with the internal thread 44, which can limit the position of the moving rod 41, thereby avoiding accidental touch and causing the insertion rod 410 to disengage from the vertical groove 37.

[0029] Further, a battery 5 is installed on the back of the volume corrector body 2 to supply electrical energy to the volume corrector body 2.

[0030] Further, the horizontal groove 35 is arranged along the side of the connecting sleeve 33, and the horizontal groove 35 is arranged in a quarter circular arc shape so that the volume corrector body 2 can rotate by 90 degrees, thereby facilitating the replacement of the battery 5.

[0031] Further, a connecting flange one 32 is fixedly connected to the bottom end of the connecting sleeve 33, and the connecting flange one 32 is fixedly connected to the top of the connecting block 31 by bolts to facilitate the disassembly or installation of the connecting sleeve 33.

[0032] Further, a connecting flange two 36 is fixedly connected to the top of the connecting column 34, and the connecting flange two 36 is fixedly connected to the lower part of the volume corrector body 2 by bolts to facilitate the disassembly or installation of the connecting column 34.

[0033] In summary, the working process of the present invention is as follows: When in use, when it is necessary to install the volumetric corrector body 2 on the flowmeter body 1, first fix the connecting column 34 under the volumetric corrector body 2 through bolts and the second connecting flange 36. Then, by pressing the moving rods 41 on both sides simultaneously towards the middle, the moving rods 41 move along the first through hole 43 and squeeze the slider 46 in the sliding cavity 45. While the slider 46 moves inward, it drives the vertical plate 48 to move through the connecting rod 47. While the vertical plate 48 moves, it drives the insertion rod 410 to move, so that the end of the insertion rod 410 retracts into the second through hole 49. At this time, the connecting column 410 can be inserted from the top of the connecting sleeve 33. The connecting column 34 moves downward along the inner cavity of the connecting sleeve 33 and presses the movable plate 38 downward. The movable plate 38 squeezes the first spring 39, causing the first spring 39 to be compressed. When the insertion rod 34 moves to the position aligned with the vertical groove 37, release the moving rod 41. Then, under the pushing action of the second spring 412, the vertical plate 48 is reset, and then the end of the insertion rod 410 is pushed out of the outside of the second through hole 49 again and inserted into the vertical groove 37. At the same time, under the elastic force of the first spring 39, the movable plate 38 always squeezes the bottom end of the connecting column 34, so that the insertion rod 410 is stably inserted into the vertical groove 37, and thus the installation of the volumetric corrector body 2 can be completed. In addition, the volumetric corrector body 2 is powered by the battery 5 on the back. When the battery 5 is out of power, the battery 5 needs to be replaced. At this time, the volumetric corrector body 2 can be pressed downward by hand. The volumetric corrector body 2 squeezes the movable plate 38 and the first spring 39 through the connecting column 34, and the insertion rod 410 moves downward along the vertical groove 37 into the horizontal groove 35. Then, rotate the volumetric corrector body 2 and the connecting column 34. At the same time, the insertion rod 410 rotates along the horizontal groove 35 until it moves to the lower part of the vertical groove 37 on the other side of the horizontal groove 35. Release the volumetric corrector body 2, and through the first spring 39 pushing the movable plate 38, the insertion rod 410 is pushed into the vertical groove 37 again. At this time, the position of the volumetric corrector body 2 is fixed again, and the volumetric corrector body 2 is rotated by 90 degrees. This facilitates exposing the installation position of the battery 5 on the back of the volumetric corrector body 2, and the battery 5 can be replaced from the side. In this way, it is not necessary to disassemble the volumetric corrector body 2 to replace the battery 5 located on the back of the volumetric corrector body 2, which is convenient for use.
