Therefore, the engagement beads 405 and the arc-shaped sliding groove 402 are engaged and slide, the engagement beads 405 and the return groove 403 are engaged, and the second spring 404 abuts against the test tube 5, so that the engagement beads 405 can slide smoothly in the arc-shaped sliding groove 402, and the engagement beads 405 can be engaged and limited by the return groove 403. Through the above setting, even if the layered test tube rack is collided, the test tube will not be tilted or poured out due to shaking, in addition, when the test tube 5 needs to be taken out, the test tube 5 only needs to be pressed again and slightly rotated, at this time the engagement beads 405 can slide out of the return groove 403, to achieve the purpose of quick taking out.

[0032] As shown in Figure 1 The material of the mounting plate 1 and the test tube box 2 is special plastic, which has excellent properties of high temperature resistance, corrosion resistance, wear resistance and chemical resistance, and is more suitable for use in the laboratory. The second spring 404, the first spring 302, the clamping bead 304 and the engagement bead 405 are all made of stainless steel, which has the characteristics of high strength, corrosion resistance, rust resistance and high temperature resistance, and is very suitable for manufacturing springs and clamping beads and other components in the laboratory. The stainless steel spring can maintain its shape and strength even after repeated loading, showing excellent elasticity and fatigue resistance. They perform well in environments where corrosion may be a problem, such as chemical laboratories, and usually do not require additional maintenance to extend their service life. Therefore, the mounting plate 1 and the test tube box 2 are light in weight and high in hardness, and the second spring 404, the first spring 302, the clamping bead 304 and the engagement bead 405 are high in strength and rust resistant, with a long service life.

Therefore, a plurality of test tube boxes 2 can be placed, and the three test tube boxes 2 do not interfere with each other. The plurality of test tubes can be divided into a plurality of groups by the plurality of partitions 6, so as to facilitate subsequent sample differentiation.

[0035] Preferably, the test tube rack comprises an integrated temperature control module capable of providing heating or cooling functions to adapt to chemical experiments requiring temperature control. The temperature control module is connected to a microcontroller through a temperature sensor to realize accurate control of the temperature of the test tube rack. The microcontroller automatically adjusts the heating element or cooling liquid flow according to the preset temperature parameters to ensure that the sample in the test tube is in a suitable temperature environment.

[0036] Preferably, the test tube rack comprises a shockproof mechanism comprising a shock-absorbing pad provided at the bottom of the mounting plate. The shock-absorbing pad is made of high-elastic rubber material to absorb vibrations caused by external impact. The shape of the shock-absorbing pad matches the bottom of the mounting plate, and the shock-absorbing pad is fixed to the bottom of the mounting plate by an adhesive or a buckle structure. When the shock-absorbing pad is impacted, it can effectively disperse and absorb the impact force, thereby protecting the test tubes in the test tube box from damage.

[0037] The implementation principle of the embodiment is as follows: first, one of the mounting plates 1 is erected, and then the mounting blocks 308 on the inner side of the mounting plate 1 are inserted into the mounting grooves 305 on both sides of the test tube box 2. When the mounting blocks 308 are inserted into the mounting grooves 305, the balls 304 do not interfere with the insertion of the mounting blocks 308 because the balls 304 are in the form of balls and because the balls 304 are provided with the first springs 302 on one side. When the mounting blocks 308 enter the bottom of the mounting grooves 305, the balls 304 are bounced back by the first springs 302 because the mounting blocks 308 are provided with the clamping grooves 307, so that the balls 304 enter the inside of the clamping grooves 307. Then, the other mounting plate 1 is installed at the other end of the test tube box 2, so that the mounting plate 1 and the test tube box 2 can be quickly installed. In addition, when the test tube box 2 needs to be removed, the balls 304 are retracted by pulling the push block 306 outward, so that the test tube box 2 can be quickly and effectively removed. Through the above arrangement, the layered clamping test tube rack can be quickly installed, and when the test tube box 2 needs to be removed, it can also be quickly disassembled.

[0038] After the installation of the test tube box 2 is completed on the installation plate 1, the test tube 5 can be inserted according to the position of the fixing seat 401, and the test tube 5 can be slightly rotated during the insertion process, so that the clamping beads 405 can smoothly enter the inside of the arc-shaped sliding groove 402, and then the test tube 5 can be slightly pressed down, at this time the second spring 404 will be pressed down by the test tube 5, and then when sliding to the end of the arc-shaped sliding groove 402, the clamping beads 405 will enter the inside of the backstop groove 403, and then the second spring 404 will rebound to lock the test tube 5, through the above setting, even if the layered clamping test tube rack is collided, the test tube will not be caused to be turned on one side due to shaking, or poured out, in addition, when the test tube 5 needs to be taken out, the test tube 5 only needs to be pressed again and slightly rotated, at this time the clamping beads 405 can slide out from the backstop groove 403, so as to achieve the purpose of quick taking out.
