Description

Technical Field

[0001] The utility model relates to the technical field of test tube racks, and more specifically, to a stackable sampling test tube rack. Background Art

[0002] In many fields such as scientific research experiments, medical testing and biological sample processing, sampling tubes are important containers. Their stable storage and efficient management are crucial to ensuring the accuracy of experimental data and the integrity of samples.

[0003] In the prior art, most test tube racks are fixed in design and difficult to adapt to test tubes of different diameters, which limits their application in various experimental scenarios. In addition, test tubes are prone to shaking or even falling in the rack due to slight vibrations or improper operation, affecting experimental efficiency and safety. At the same time, most traditional test tube racks are laid flat or simply stacked, which not only takes up a lot of space, but also has poor stacking stability, which can easily lead to test tube damage or data loss. In response to the above problems, this device was invented. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a stackable sampling test tube rack to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stackable sampling test tube rack, including a pad, four corners of the top of the pad are provided with plug-in holes, a No. 1 magnet is fixedly installed at the bottom of the plug-in hole, four corners of the bottom of the pad are fixedly installed with supporting legs, a No. 2 magnet is fixedly installed at the bottom of the supporting legs, a plurality of placement holes are evenly provided on the pad, a number of placement sleeves equal to the number of placement holes are fixedly installed at the bottom of the pad, a limiting assembly equal to the number of placement holes is arranged on the top of the pad, the limiting assembly includes arc-shaped fixing blocks fixedly installed on both sides of the top of the placement hole, and the arc-shaped fixing blocks on both sides are arranged opposite to each other, a connecting spring is fixedly installed on the inner side of the arc-shaped fixing block, and an arc-shaped pressure plate is fixedly installed on the inner side of the connecting spring.

[0006] Furthermore, the backing plate is made of ABS plastic.

[0007] Furthermore, pull handles are fixedly installed on both sides of the pad, and the outer wall surfaces of the pull handles are processed with anti-slip patterns.

[0008] Furthermore, the diameter of the plug hole is equal to the diameter of the leg.

[0009] Furthermore, both the No. 1 magnet and the No. 2 magnet are made of neodymium iron boron magnets.

[0010] Furthermore, a rubber pad is fixedly installed on the bottom of the placement sleeve.

[0011] Further, the height of the placement sleeve is less than the height of the leg.

[0012] Further, the arc-shaped pressing plate is made of silica gel material.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model is provided with a limiting component. The design of the limiting component enables the test tube rack to adapt to test tubes of different sizes. Through the elastic force of the connecting spring, the arc-shaped pressing plate can closely adhere to the outer wall of the test tube, generating friction to prevent the test tube from shaking or falling. This design not only improves the stability of the test tube in the placement hole but also enhances the flexibility and practicality of the test tube rack, meeting the requirements of different experimental or application scenarios;

[0015] 2. The present utility model realizes the stable stacking of test tube racks by using magnetic adsorption (the first magnet and the second magnet) between the insertion holes on the backing plate and the bottom legs. This design not only improves the stacking stability but also avoids the sliding or collapse phenomena that may occur in the traditional stacking method, thereby enhancing the safety during use.

[0025] In order to enable those skilled in the art of this technical field to better understand the solution of this application, the following further detailed description of this application is made in conjunction with the drawings and specific implementation manners.

[0026] Embodiment:

[0027] Referring to the attached Figure 1 , a stackable sampling test tube rack in this embodiment realizes stable stacking through the magnetic adsorption between the insertion holes 2 on the base plate 1 and the legs 4 at the bottom, and at the same time uses the limiting component 8 to ensure the stable placement of the sampling test tubes in the placement holes. It includes a base plate 1, wherein the base plate 1 is made of ABS plastic. ABS plastic has the advantages of high strength and wear resistance, which can significantly extend the service life of this sampling test tube rack. Lifting handles 6 are fixedly installed on both sides of the base plate 1, which is convenient for operators to carry the test tube rack. The outer wall surface of the lifting handle 6 is processed with anti-slip lines, improving the convenience and safety of use.

[0028] Referring to the attached Figure 1 , Figure 4 and Figure 5 , insertion holes 2 are opened at the four corners of the top of the base plate 1. A first magnet 3 is fixedly installed at the bottom of the insertion hole 2. Legs 4 are fixedly installed at the four corners of the bottom of the base plate 1. A second magnet 5 is fixedly installed at the bottom of the leg 4. The aperture of the insertion hole 2 is equal to the diameter value of the leg 4. Both the first magnet 3 and the second magnet 5 are made of neodymium iron boron magnets. When stacking, insert the legs 4 at the bottom of the upper test tube rack into the insertion holes 2 of the lower test tube rack, and use the mutual attraction between the first magnet 3 and the second magnet 5 to achieve stable stacking, improving the stability and safety of stacking.

[0029] Referring to the attached Figures 1 - 3, a plurality of placement holes are evenly formed in the backing plate 1. At the bottom of the backing plate 1, a plurality of placement sleeves 7 equal in number to the placement holes are fixedly installed. At the bottom of the placement sleeve 7, a rubber cushion block 9 is fixedly installed. The rubber cushion block 9 provides a buffering effect and protects the bottom of the test tube from damage. The height of the placement sleeve 7 is less than the height of the leg 4. On the top of the backing plate 1, a limiting component 8 equal in number to the placement holes is provided. The limiting component 8 includes arc-shaped fixing blocks 801 fixedly installed on both sides of the top of the placement hole, and the two arc-shaped fixing blocks 801 are arranged facing each other. An connecting spring 802 is fixedly installed inside the arc-shaped fixing block 801. An arc-shaped pressing plate 803 is fixedly installed inside the connecting spring 802. And the arc-shaped pressing plate 803 is made of silica gel material, which protects the test tube from damage. At the same time, the silica gel material has good softness and aging resistance, which can ensure that the arc-shaped pressing plate 803 maintains a stable shape and elasticity during long-term use.

[0030] When the test tube is placed into the placement hole, the outer wall of the test tube will contact the arc-shaped pressing plate 803. Due to the elastic force of the connecting spring 802, the arc-shaped pressing plate 803 will closely adhere to the outer wall of the test tube, thereby generating a certain frictional force to prevent the test tube from shaking or falling in the placement hole. Since the elastic force of the connecting spring 802 is adjustable, the limiting component 8 can adapt to test tubes of different sizes to a certain extent, making the test tube rack more flexible and practical, and capable of meeting the requirements of different experimental or application scenarios.

[0031] Finally: The above description is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
