Based on the above scheme, the second straight pipe section 320 is connected with the main machine, and as a fixed straight pipe section, the valve body 400 is driven to move by the sliding of the meter checking platform 200 on the guide rail 100, so that the distance between the first straight pipe section 310 and the second straight pipe section 320 is changed, and the flow meters with different specifications can be adapted. The valve body 400 can be the valve body 400 disclosed in patent No. CN201720396219.7, and can fix the first straight pipe section 310 and move it. The fixing frame 500 and the second straight pipe section 320 are slidable to support the second straight pipe section 320, so that the table check 200 can move while maintaining the support function of the second straight pipe section 320.
In a particular use, the flow meter is placed on the guide rail 100 and the meter checking platform 200 is pushed, allowing the meter checking platform 200 to slide on the guide rail 100 until the first straight pipe section 310 and the second straight pipe section 320 can be connected with the flow meter.
In order to further adapt to the flow meters with more specifications, the meter checking platform 200 is provided with a supporting platform 600 with adjustable height for placing the flow meters. When the first straight pipe section 310 and/or the second straight pipe section 320 are matched with the flowmeter, the height of the support table 600 is adjusted to enable the flowmeter to be matched with the first straight pipe section 310 and/or the second straight pipe section 320 more conveniently, the assembly is better, the flowmeter is further suitable for flowmeters with more specifications, and the specific adjusting mode can adopt height adjustment of a dismounting mode.
In further optimization, the table testing table 200 is provided with an adjusting assembly 700 for adjusting the height of the supporting table 600. The height of the meter checking table 200 can be adjusted by the adjusting assembly 700, which is more convenient.
In a preferred embodiment, the adjusting assembly 700 includes a turntable 710 and a linkage assembly 720, the turntable 710 is linked with the support platform 600 through the linkage assembly 720, the linkage assembly 720 includes a driving shaft 721 linked with the turntable 710, a driven shaft 722 linked with the driving shaft 721, and a lifting rod 723 linked with the driven shaft 722, the lifting rod 723 is connected to the test platform 200 in a vertically movable manner, the support platform 600 is disposed on the lifting rod 723, and the lifting rod 723 is driven by the driven shaft 722 to move up and down on the test platform 200.
The principle is as follows: the turntable 710 is rotated to drive the linkage assembly 720 through the turntable 710, and then the linkage assembly 720 is used to lift or lower the support platform 600, specifically, the turntable 710 is rotated to drive the driving shaft 721 to rotate, the driving shaft 721 is used to drive the driven shaft 722 to rotate, and the driven shaft 722 is matched with the lifting rod 723 to drive the lifting rod 723 to lift.
More specifically, one end of the lifting rod 723 is connected to the test table 200 by a screw so as to be movable up and down, and the other end is rotatably connected to the support table 600; the driven shaft 722 drives the lifting rod 723 to rotate, so as to drive the lifting rod 723 to move up and down on the supporting platform 600.

The driving mode is simpler, the lifting of the lifting rod 723 does not need to be directly operated, and the driving mode is indirectly driven in a rotating mode.
In order to further improve the driving stability and the self-locking effect, one end of the driven shaft 722 opposite to the lifting rod 723 is a worm structure 724, a worm wheel 800 matched with the worm structure 724 of the driven shaft 722 is sleeved on the lifting rod 723 at a position corresponding to the driven shaft 722, a convex block 725 of the worm wheel 800 is sleeved on the lifting rod 723, and a groove 810 matched with the convex block 725 is formed in the inner side wall of the worm wheel 800 at a position corresponding to the convex block 725.
When the driving shaft 721 drives the driven shaft 722 to rotate, the driven shaft 722 drives the worm wheel 800 to rotate through the worm structure 724, the lifting rod 723 is driven to rotate through the matching of the groove 810 and the bump 725 on the worm wheel 800 when the worm wheel 800 rotates, and due to the self-locking effect of the mutual matching of the worm wheel 800 and the worm, the rotation of the driving shaft 721 can be further locked, the driving stability can be improved, and the supporting stability of the supporting table 600 is improved. The driving mode can convert horizontal rotation into displacement in the vertical direction and is convenient to implement.
In order to improve the matching effect of the worm structure 724 and the worm wheel 800, two limiting members 900 for limiting the worm wheel 800 to move up and down on the lifting rod 723 are fixedly connected to the meter checking platform 200, and the two limiting members 900 are respectively located on the upper side and the lower side of the worm wheel 800.
The limiting part 900 limits the worm gear 800, so that the situation that the worm gear 800 is driven to move when the lifting rod 723 moves up and down to cause the worm gear 800 and the worm structure 724 to be separated from a matching effect is avoided, and the matching stability can be improved. In addition, the matching effect of the structure is obvious in the driving mode, and the lifting rod 723 can move up and down by keeping the worm gear 800 rotating in place through the matching mode of the groove 810 and the lug 725.
As a further improvement, the edge of the limiting member 900 opposite to the worm structure 724 does not exceed the edge of the worm wheel 800.
