DETAILED DESCRIPTION

[0024] In order to make the purpose and advantages of the utility model more clear and obvious, the following will be specifically described by combining with the embodiment.The following text is only used to describe one or several specific embodiments of the utility model and does not strictly limit the protection scope requested by the utility model.

[0025] For example, Figures 1 to 4As shown, a teaching reagent tube fixing frame, including a frame body 10, the lower end of the frame body 10 is fixedly installed with a bottom plate 11, the upper side of the bottom plate 11 is provided with a plurality of partitions 12 in the vertical direction, the partition 12 is fixedly connected with the frame body 10, a plurality of through holes 13 are formed in the partition 12, the through holes 13 of adjacent partitions 12 are aligned in the vertical direction, further comprising: a limiting mechanism 20, the limiting mechanism 20 is provided with a plurality of and is installed on the plurality of through holes 13, for limiting the reagent tube, the installation direction of the two limiting mechanisms 20 adjacent in the vertical direction is staggered, the limiting mechanism 20 includes two sliding grooves 21 provided outside the through hole 13, the sliding groove 21 is fixedly connected with the partition 12, two limiting rollers 22 are slidably connected between the two sliding grooves 21, the two limiting rollers 22 are respectively located at both ends of the through hole 13, and a first spring 23 is connected between the end of the limiting roller 22 and the sliding groove 21; a lifting mechanism 30, the lifting mechanism 30 is provided with a plurality of and is located on one side of the bottom plate 11 close to the through hole 13, for adjusting the height position of the reagent tube, the lifting mechanism 30 includes a lifting plate 31 provided below the through hole 13, the lifting plate 31 is slidably installed on the bottom plate 11 in the vertical direction, and a plurality of second springs 32 are connected between the lifting plate 31 and the bottom plate 11.

[0026] It should be noted that the partition 12 is provided with two, and the installation direction of the two limiting mechanisms 20 adjacent in the vertical direction is perpendicular to each other.

[0027] In this embodiment, the reagent tube is placed into the through hole 13, in this process, the bottom of the reagent tube first contacts the limiting roller 22, the bottom of the reagent tube pushes the limiting roller 22 to slide outward, when the bottom of the reagent tube passes through the through hole 13, the first spring 23 pushes the limiting roller 22 to slide inward along the sliding groove 21 under the action of elasticity, so that the limiting roller 22 is close to the outer wall of the reagent tube, because the installation direction of the two limiting mechanisms 20 adjacent in the vertical direction is staggered, the limiting rollers 22 of different limiting mechanisms 20 are close to the outer wall of the reagent tube in different directions, so as to limit and fix the reagent tube, which is convenient to adapt to reagent tubes of different diameters and improves the applicability, and after the bottom of the reagent tube contacts the lifting mechanism 30, the reagent tube drives the lifting plate 31 to move downward under the action of its own gravity, the second spring 32 is extruded by the lifting plate 31 and the height is reduced, so that the lifting plate 31 is pressed downward by the reagent tube on one side and is pushed upward by the second spring 32 on the other side, and finally the height position of the lifting plate 31 and the bottom of the reagent tube is kept fixed after balance, so that the distance between the bottom of the reagent tube and the partition 12 is kept fixed, when the reagent tube is short, the weight of the reagent tube is small, so that the distance between the bottom of the reagent tube and the partition 12 is small after balance, reducing the situation that the reagent tube with shorter length is separated from the partition 12 and poured after being placed into the through hole 13, which is convenient to adapt to reagent tubes of different lengths and improves the applicability.

[0028] As shown in Figure 2 and Figure 3 , the limiting roller 22 includes two sliding blocks 221 respectively slidingly matched with the two sliding grooves 21, and a roller 222 rotatably connected between the two sliding blocks 221. The outer side of the sliding block 221 is fixedly connected with a first baffle 223. The two ends of the sliding groove 21 are fixedly connected with second baffles 224. The first spring 23 is connected between the first baffle 223 and the second baffle 224.

[0029] It should be noted that the cross-sectional shape of the limiting hole 211 is rectangular, and the dimension of the first baffle 223 along the vertical direction is greater than the dimension of the limiting hole 211 along the vertical direction.

[0030] In this embodiment, during the process that the bottom of the reagent tube passes through the through hole 13, the bottom of the reagent tube pushes the limiting roller 22 to move outward, so that the roller 222 drives the sliding block 221 to slide outward along the sliding groove 21, and the sliding block 221 drives the first baffle 223 to approach the first spring 23. After the bottom of the reagent tube passes through the roller 222, the tube wall of the reagent tube no longer pushes the roller 222 to move outward due to the unchanged tube diameter of the reagent tube. At this time, the first spring 23 pushes the first baffle 223 away from the second baffle 224 under the elastic action, so that the first baffle 223 drives the sliding block 221 to slide inward along the sliding groove 21, and the sliding block 221 drives the roller 222 to approach the tube wall of the reagent tube and clamp the reagent tube, thereby facilitating the limiting and fixing of the reagent tube. In this process, the sliding block 221 cooperates with the sliding groove 21, so that the sliding process of the limiting roller 22 along the sliding groove 21 is more stable. The roller 222 is rotatably connected with the sliding block 221, so that when the reagent tube passes between the two limiting rollers 22, the tube wall of the reagent tube and the roller 222 relatively roll, thereby facilitating the reagent tube to pass between the two limiting rollers 22.

[0031] As shown in Figure 2 and Figure 3 , the end of the limiting roller 22 away from the first spring 23 is provided with a limiting column 24, and the limiting column 24 is slidingly installed on the sliding groove 21.

[0032] In this embodiment, the first spring 23 pushes the limiting roller 22 to slide along the sliding groove 21 under the elastic action. The limiting column 24 hinders the limiting roller 22 from continuously sliding inward along the sliding groove 21, so that after the limiting column 24 limits the limiting roller 22, there is a gap between the two limiting rollers 22. During the process that the bottom of the reagent tube moves downward and passes between the two limiting rollers 22, the bottom of the reagent tube pushes the limiting roller 22 to move outward, thereby reducing the situation that the limiting roller 22 hinders the bottom of the reagent tube from being inserted into the through hole 13 between the two limiting rollers 22.

[0033] As shown in Figure 2 and Figure 3As shown, the interior of the slide groove 21 has several limiting holes 211 along the sliding direction of the slider 221, and the limiting post 24 slides in conjunction with the limiting holes 211 in the vertical direction.

[0034] In this embodiment, when it is necessary to adjust the size of the gap between the two limiting rollers 22, the limiting post 24 is pulled out from the limiting hole 211 and moved along the sliding direction of the limiting roller 22 so that the limiting post 24 is aligned with the limiting hole 211 at a suitable position. The limiting post 24 is then inserted into the limiting hole 211 so that the limiting post 24 limits the limiting roller 22. By adjusting the insertion position of each of the two limiting posts 24, the distance between the two limiting posts 24 is adjusted, thereby adjusting the size of the gap between the two limiting rollers 22, so that when the bottom of the reagent tube passes through the gap, it pushes the two limiting rollers 22 to move outward.

[0035] like Figure 2 and Figure 3 As shown, the lifting plate 31 has several sliding holes 311 inside, and several sliding columns 111 are fixedly connected to the base plate 11. The sliding columns 111 and the sliding holes 311 slide in a vertical direction.

[0036] It should be noted that the second spring 32 is located outside the slide bar 111, and several second springs 32 correspond one-to-one with several slide bars 111.

[0037] In this embodiment, the sliding column 111 cooperates with the sliding hole 311, making the process of the lifting plate 31 sliding up and down along the base plate 11 more stable.

[0038] like Figure 1 and Figure 4 As shown, slots 112 are provided at both ends of the base plate 11, and several insertion holes 101 are provided on the inner walls of both sides of the frame 10 in the vertical direction. The slots 112 and the insertion holes 101 are slidably connected by limit pins 14.

[0039] In this embodiment, when it is necessary to adjust the height of the base plate 11, the limiting pin 14 is pulled out from the insertion hole 101 and the slot 112, and the base plate 11 is moved up and down along the frame 10 so that the slot 112 is aligned with the insertion hole 101 at the appropriate position. The limiting pin 14 is then inserted into the slot 112 and the insertion hole 101 to limit the frame 10 and the base plate 11, so that the height of the base plate 11 remains fixed. This allows the height of the base plate 11 to be adjusted, thereby adjusting the distance between the lifting plate 31 and the partition plate 12 when no reagent tube is placed, which facilitates further adaptation to reagent tubes of different lengths.

[0040] The utility model discloses a working principle is as follows: reagent tube passes through the hole 13 and is placed into the baffle 12, and the bottom of reagent tube is attached with the upper surface of lifting plate 31, and lifting plate 31 is positioned along the vertical direction to reagent tube, and first spring 23 is pushed close to the pipe wall of reagent tube under the elastic action of limiting roller 22, so that two limiting rollers 22 are positioned and fixed along the horizontal direction to reagent tube, and since limiting mechanism 20 is provided with a plurality of and the installation direction is mutually staggered along the vertical direction, so that each limiting mechanism 20 is positioned along the horizontal direction of different angles to reagent tube, improve the stability of fixed reagent tube, and adapt to the reagent tube of different pipe diameter, and reagent tube is driven lifting plate 31 to move down under the action of gravity, so that lifting plate 31 is pressed down on one side and is pushed up on the other side by second spring 32, after reaching the balance, the distance between lifting plate 31 and baffle 12 is adjusted, and the reagent tube of different length size is different in weight, so that when the reagent tube of short length is placed, the distance between lifting plate 31 and baffle 12 is also close, so as to reduce the condition that the reagent tube of short length is separated from baffle 12 and pours, and adapt to the reagent tube of different length size.

[0041] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled person in the art, under the premise of not departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection scope of the utility model. The structure, device and operation method not specifically described and explained in the utility model are implemented according to conventional means in the art, and are not specially described and limited.
