Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 As shown;

[0027] An adjustable auxiliary device for measurement and detection, comprising a bracket 1 and a placement plate 11 arranged inside the bracket 1;

[0028] In this implementation scheme: after checking the public (announcement) number: CN2559410Y discloses a test tube rack, in order to solve the technical problems existing in this prior art, such as the above background technology disclosure that "this auxiliary device cannot place measuring tools of different diameters when placing measuring tools", this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a clamping component 2 and a lifting component 3 are added on this basis.

[0029] More specifically:

[0030] like Figures 1 to 4 As shown;

[0031] Combining the above:

[0032] In order to clamp measuring cylinders of different diameters, the adjustable metering and detection auxiliary device further includes a clamping assembly 2 disposed inside the placement plate 11;

[0033] The clamping assembly 2 includes a plurality of positioning holes 22 evenly arranged inside the placing plate 11, and a plurality of clamping plates 21 are rotatably connected to the bottom surface of the placing plate 11 through a bearing seat, and the plurality of clamping plates 21 are arranged around the positioning hole 22 as the axis, and a plurality of fixing blocks 23 are fixedly connected to the bottom surface of the placing plate 11, and each fixing block 23 is on the same axis as the corresponding clamping plate 21, and a limiting groove 24 is arranged inside the fixing block 23, and a positioning groove 26 is arranged on a side of the clamping plate 21 close to the fixing block 23, and a support rod 25 is arranged between the fixing block 23 and the clamping plate 21, and rollers are arranged at both ends of the support rod 25, and the two rollers are respectively inserted into the interior of the positioning groove 26 and the limiting groove 24, and are rollingly connected to the clamping plate 21 and the fixing block 23 through the positioning groove 26 and the limiting groove 24, and a spring 27 is arranged inside the fixing block 23, and the two ends of the spring 27 are respectively fixedly connected to the support rod 25 and the fixing block 23.

[0034] In this implementation scheme: when it is necessary to place a measuring tool, the operator will insert the measuring cylinder into the positioning hole 22 and press downward, each clamp 21 will be squeezed and rotated in the direction of the fixed block 23, and the support rod 25 will be forced to move upward inside the limiting groove 24, and the two rollers will roll inside the positioning groove 26 and the limiting groove 24 respectively, and the spring 27 will be compressed by force until the measuring cylinder no longer moves. The spring 27 will press the support rod 25 downward due to the elastic potential energy, and the clamp 21 will clamp the measuring cylinder, thereby realizing the feature of clamping measuring cylinders of different diameters.

[0035] Going further:

[0036] In an optional embodiment, a force-applying cylinder 28 is disposed inside the positioning hole 22 , and the force-applying cylinder 28 is slidably connected to the placement plate 11 through the positioning hole 22 .

[0037] In this embodiment, when the measuring cylinder needs to be taken out, the force-applying cylinder 28 is pressed down, and the force-applying cylinder 28 rotates the plurality of clamping plates 21 away from the measuring cylinder, thereby releasing the clamping of the measuring cylinder, and the measuring cylinder is taken out.

[0038] Going further:

[0039] In an optional embodiment, a rubber pad is fixedly connected to one adjacent side of each clamping plate 21 .

[0040] In this embodiment, when the clamping plate 21 clamps the measuring cylinder, the rubber pad not only increases the friction between the two to make the clamping more stable, but also has a certain degree of flexibility to prevent hard contact with the measuring cylinder to cause damage.

[0041] Going further:

[0042] In an optional embodiment, it further includes a lifting assembly 3 disposed inside the bracket 1;

[0043] The lifting assembly 3 includes a plurality of slide grooves 31 that are evenly and symmetrically opened inside the bracket 1. Two sliders 32 are symmetrically and fixedly connected to the two ends of the placement plate 11. Each slider 32 is inserted into the corresponding slide groove 31. The slider 32 is slidably connected to the bracket 1 through the slide groove 31. A screw hole 33 is opened inside each slider 32. A screw rod 35 is arranged inside each screw hole 33. The screw 35 is threadedly connected to the slider 32 through the screw hole 33. A knob 34 is fixedly connected to the end of the screw 35 away from the slider 32.

[0044] In this embodiment: when it is necessary to clamp measuring cylinders of different heights, the knob 34 is turned, and the screw 35 will rotate inside the screw hole 33, so that the knob 34 is away from the bracket 1, and the limit on the slider 32 is released. Then, the slider 32 can move up and down inside the slide groove 31, and the knob 34 is reversed again to make it and the bracket 1 squeeze each other, thereby strengthening the direct friction between the two and realizing the limit on the slider 32.

[0045] The working principle and use process of the utility model are as follows: when it is necessary to place a measuring tool, the operator will insert the measuring cylinder into the positioning hole 22 and press it downward, each clamping plate 21 will be squeezed and rotated in the direction of the fixing block 23, the support rod 25 will be forced to move upward inside the limiting groove 24, the two rollers will respectively roll inside the positioning groove 26 and the limiting groove 24, the spring 27 will be forced to be compressed until the measuring cylinder no longer moves, the spring 27 will press the support rod 25 downward due to the elastic potential energy, and the clamping plate 21 will clamp the measuring cylinder, thus realizing the special feature of clamping measuring cylinders of different diameters. When it is necessary to take out the measuring cylinder, the force-applying cylinder 28 is pressed down, and the force-applying cylinder 28 will rotate the plurality of clamps 21 in the direction away from the measuring cylinder, loosening the clamping of the measuring cylinder, so that the measuring cylinder can be taken out. When it is necessary to clamp the measuring cylinders of different heights, the knob 34 is turned, and the screw 35 will rotate inside the screw hole 33, so that the knob 34 is away from the bracket 1, and the limit on the slider 32 is loosened, so that the slider 32 can move up and down inside the slide groove 31, and the knob 34 is reversed again to make it and the bracket 1 squeeze each other, thereby strengthening the direct friction between the two and realizing the limit on the slider 32.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
