[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figure 1-4 The sterile test tube rack shown includes a base 1, a top plate 2 located directly above the base 1, and a storage mechanism 3 connecting the base 1 and the top plate 2.

[0019] The top plate 2 has multiple tube insertion holes 201 evenly spaced for inserting test tubes. Each tube insertion hole 201 has a fixing part 4 connected to the top plate 2. Specifically, as shown... Figure 4 As shown, the fixing part 4 includes two elastic clamping assemblies symmetrically arranged about the tube insertion hole 201. Each elastic clamping assembly includes an arc-shaped clamping block 41, a fixing block 42, a compression spring 43, and a guide slide rod 44. The fixing block 42 is fixed to the top plate 2. The arc-shaped clamping block 41 is horizontally fixed to the side end of the arc-shaped clamping block 41 near the tube insertion hole 201 by the compression spring 43. One end of the guide slide rod 44 is horizontally fixed to the side end of the arc-shaped clamping block 41, and the other end of the guide slide rod 44 slides through the fixing block 42. The two arc-shaped clamping blocks... 41 The inner diameter of the through hole formed when the test tube is not clamped is smaller than the diameter of the tube insertion through hole 201. The upper inner edge of the arc-shaped clamp 41 is set as a guide slope 4101. When the test tube is inserted, the bottom of the test tube first contacts the guide slope 4101. The two arc-shaped clamps 41 move away from each other under the pressure of the test tube on their guide slope 4101 until the test tube is inserted downwards. The two arc-shaped clamps 41 then hold the test tube stably under the action of the compression spring 43, so that the test tube is not easy to shake during the test.

[0020] Specifically, the storage mechanism 3 includes several scissor-type connecting parts installed on the periphery between the base 1 and the top plate 2, an adjustment part that is connected to each of the several scissor-type connecting parts, and a transmission part that is connected between two adjacent adjustment parts. The adjustment part and the transmission part enable the several scissor-type connecting parts to move synchronously, thereby causing the top plate 2 to move horizontally in the vertical direction.

[0021] More specifically, such as Figure 3As shown, the scissor-type connection includes two connecting rods 31 and limiting sliders 32 rotatably mounted at both ends of the connecting rods 31. The middle parts of the two connecting rods 31 are rotatably connected. The end faces of the base 1 and the top plate 2 that are close to each other are provided with a first limiting groove 101 and a second limiting groove 202 for the limiting sliders 32 to slide horizontally. The adjustment part includes a threaded rod 33 and a nut 34. The threaded rod 33 is rotatably mounted on the inner side of the first limiting groove 101. Two opposite threaded sections (threads not shown in the figure) are symmetrically arranged on the threaded rod 33, located on the base 1. The two limiting sliders 32 on the base are respectively threaded onto the two threaded sections of the threaded rod 33. One end of the threaded rod 33 passes through the base 1 and is fixed to the nut 34. The transmission part includes a first bevel gear 35 and a second bevel gear 36. The first bevel gear 35 and the second bevel gear 36 are respectively coaxially fixedly sleeved on the ends of two adjacent threaded rods 33 that are close to each other, and the first bevel gear 35 and the second bevel gear 36 mesh with each other. When the threaded rod 33 is rotated, the two limiting sliders 32 located on the base 1 can be driven to move closer or further away from each other synchronously.

[0022] In order to make the testing frame more aesthetically pleasing, the fixing part 4 is located on the lower side of the top plate 2. The hidden design of the fixing part 4 makes the testing frame more aesthetically pleasing. At the same time, the fixing part 4 is less likely to be contaminated by the testing substances, making cleaning easier.

[0023] The working principle of this utility model is as follows: In use, depending on the height of the test tube, the operator can rotate any one of the threaded rods 33 by rotating the cap 34, which can cause several scissor-type connecting parts to move synchronously (the specific thread settings on several threaded rods 33 can be achieved by conventional technical means in the prior art), thereby causing the top plate 2 to move vertically. The top plate 2 can be adjusted to a suitable height. Then, the test tube is vertically inserted into the tube insertion hole 201. The bottom of the test tube first contacts the guide slope 4101. The two arc-shaped clamps 41 move away from each other under the pressure of the test tube on the guide slope 4101 until the test tube is inserted downwards. The two arc-shaped clamps 41 then stably clamp the test tube under the action of the compression spring 43, so that the test tube is not easy to shake during the test. After use, the testing rack is cleaned and disinfected according to relevant hygiene standards. Then, the cap 34 is turned so that the top plate 2 moves closer to the base 1 until the testing rack is completely folded, effectively improving the ineffective occupation of testing table space.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
