[0032] In the embodiment of the utility model, the flow meter clamping device 100 is applied to a plurality of flow meters 200, wherein the flow meter 200 is provided with a flow channel 200a, and the flow meter clamping device 100 comprises: a base 10, comprising a body 11 and an adjusting end 12 and a fixed end 13 arranged at both ends of the body 11; an adjusting tube 20 and a fixed tube 30, wherein the adjusting tube 20 is installed at the adjusting end 12 and has a first liquid passage 20a connected to the flow channel 200a, and the fixed tube 30 is installed at the fixed end 13, A second liquid passage 30a connected to the flow channel 200a is provided; a plurality of transfer tubes 40 are arranged at intervals along the length direction of the main body 11 and are slidably connected to the main body 11, and the transfer tube 40 is provided with a third liquid passage 40a. The regulating tube 20, the fixed tube 30 and two adjacent transfer tubes 40 can form a clamping area for clamping the flow meter 200, and the regulating tube 20 can move toward or away from the fixed end 13 to clamp and fix the flow meter 200 in the clamping area.

[0033] Specifically, the base 10 is formed by splicing metal profiles, and the body 11 is extended in a rectangular shape as a whole, and its two opposite ends are the regulating end 12 and the fixed end 13. The flow meter 200 can be a commercially available flow meter with high accuracy. The regulating tube 20 and the fixed tube 30 are also made of metal materials, and the first liquid passage 20a and the second liquid passage 30a are formed by processing. The regulating tube 20 is installed at the regulating end 12, and the fixed tube 30 is installed at the fixed end 13, and is fixedly connected to the body 11.

[0034] In the present application, the regulating tube 20, the fixed tube 30 and the two adjacent transfer tubes 40 can form a clamping area for clamping the flow meter 200. In the actual test process, the flow meter 200 can be placed in the clamping area in advance, and the regulating tube 20 is manipulated to move toward the fixed end 13, thereby clamping and fixing multiple flow meters 200 in the clamping area. After the test is completed, the regulating tube 20 is manipulated to move toward the side away from the fixed end 13, thereby releasing the multiple flow meters 200 and removing them from the clamping area. From the above, it can be seen that the flow meter clamping device 100 of the present application can clamp multiple flow meters 200 in a single test, which is not only convenient for testing and carrying, but also does not require the use of multiple clamping tables, which can greatly reduce the test cost.

[0035] Please see again Figure 1 and Figure 3In the present application, the adjusting tube 20 includes a first tube body 21 and an adjusting nut 22, wherein the base 10 is formed with a sliding connection hole 42b by mechanical processing, the adjusting nut 22 can be rotatably inserted into the mounting hole and connected to the adjusting end 12, and the adjusting nut 22 can be rotated relative to the base 10 under the action of external force, and the adjusting nut 22 is provided with an adjusting threaded hole, and the outer side of the first tube body 21 is formed with an external thread matching therewith by mechanical processing, and the first tube body 21 is penetrated into the adjusting threaded hole, and its external thread is meshed with the internal thread in the adjusting threaded hole. In the present application, the first tube body 21 is connected to the adjusting end 12 by the adjusting nut 22, and its structure is simple, and the first tube body 21 can be moved toward or away from the fixed end 13 by rotating the adjusting nut 22, and its operation is simple and convenient to use, and after the flow meter 200 is clamped and fixed, the first tube body 21 will not be displaced, thereby ensuring the stability of the test.

[0036] Further, the adjusting tube 20 further includes a plurality of hand cranks 23, which are connected to the adjusting nut 22 by welding and are evenly spaced along the circumference of the adjusting nut 22. By adjusting the hand cranks 23, it is convenient for the user to rotate the adjusting nut 22.

[0037] Please see again Figure 4 In order to facilitate the installation of the adapter tube 40, in one embodiment of the utility model, the adapter tube 40 also includes a second tube body 41 and a mounting seat 42, wherein the mounting seat 42 is provided with a snap-on hole 42a and a sliding connection hole 42b, the base 10 is provided with a sliding connection guide rail 14, the sliding connection guide rail 14 is passed through the sliding connection hole 42b, and part of the second tube body 41 is snap-on in the snap-on hole 42a.

[0038] Specifically, the mounting seat 42 includes a first seat body 421 and a second seat body 422 made of metal profiles, wherein the first seat body 421 is detachably connected to the second seat body 422, wherein the first seat body 421 is provided with a first connection hole 421a, and the second seat body 422 is provided with a second connection hole 422a, and a connecting member (not shown) is passed through the first connection hole 421a and the second connection hole 422a to connect the first seat body 421 and the second seat body 422.

[0039] Furthermore, the mounting seat 42 further includes a third seat body 423, which is also made of a metal profile. The bottom of the sliding connection hole 42b is open. The third seat body 423 is magnetically connected to the side of the first seat body 421 away from the second seat body 422, and covers the open end of the sliding connection hole 42b. It can be understood that a magnet can be arranged on the third seat body 423 so that it can be magnetically adsorbed on the first seat body 421. In the present application, the cross section of the sliding connection guide rail 14 is circular, and the cross section of the sliding connection hole 42b is a half-waist hole. The first seat body 421 is arranged as a whole, and its opening is blocked by the third seat body 423, so that the first seat body 421 can be more firmly limited to the sliding connection guide rail 14. In addition, when one of the transfer tubes 40 needs to be removed from the base 10, it is only necessary to lift the first seat body 421 upwards.

By providing the limiting protrusion 4211, it can be ensured that the first seat body 421 and the third seat body 423 will not be relatively displaced during use, thereby making the connection of the transfer tube 40 more secure.

[0041] In one embodiment of the present invention, the transfer tube 40 further includes a sealing ring 44, which is made of silicone or rubber material. The sealing ring 44 can be arranged on the outer side of the opening of the third liquid passage 40a through a groove or glue. After the flow meter 200 is clamped and fixed, the sealing ring 44 can elastically abut against the flow meter 200 and the second tube body 41. In this way, the liquid can be prevented from flowing out from the gap between the two.
