[0002] In the laboratory, test tubes are commonly used experimental instruments, and test tube racks are used to hold test tubes for convenient experimental operations. Currently, most common test tube racks are single-layer structures, which can hold a limited number of test tubes. When more test tubes need to be placed, multiple test tube racks are often required, which not only takes up a lot of space but also makes it inconvenient to manage and transport them uniformly. In addition, some existing multi-layer test tube racks are fixed structures, and the number of layers cannot be adjusted according to actual needs, resulting in poor flexibility in use.

[0003] Therefore, it is necessary to provide a new multi-layer stacked test tube rack to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer stackable test tube rack that can reduce floor space and has high flexibility of use.

[0005] To solve the above-mentioned technical problems, the multi-layer stacked test tube rack provided by this utility model includes: a placement plate and two side blocks fixedly installed on the top of the placement plate. The top of the placement plate has multiple placement slots. A common support horizontal plate is fixedly installed on the side of the two side blocks that are close to each other. The support horizontal plate has multiple support holes, and the multiple placement slots are respectively adapted to the multiple support holes. The placement plate has four guide holes. Outer protrusions are fixedly installed on the outer walls of both sides of the side blocks. Two guide posts are fixedly installed on the top of each of the two outer protrusions. The four guide holes are respectively adapted to the four guide posts. The placement plate has two assembly ports. Restriction slots are opened on both sides of the placement plate. The two restriction slots are respectively connected to the two assembly ports. Elastic mounting seats are fixedly installed on the top of each of the two outer protrusions. Locking strips are fixedly installed on the side of each of the two elastic mounting seats that are far from each other. The two locking strips are respectively adapted to the two restriction slots.

[0006] Furthermore, square sliding pillars are fixedly installed on the opposite sides of the two side blocks, and connecting plates are slidably installed on the two square sliding pillars. Connecting folding strips are fixedly installed on the opposite sides of the two connecting plates, and pushing plates are fixedly installed on the opposite sides of the two connecting folding strips. The two pushing plates are respectively adapted to the two limiting sockets. Return springs are sleeved on the two square sliding pillars. The opposite ends of the two return springs are fixedly connected to the two side blocks, and the opposite ends of the two return springs are fixedly connected to the two connecting plates.

[0007] Furthermore, operating ears are fixedly installed on the top of both connecting plates.

[0008] Furthermore, the elastic mounting base is made of spring steel.

[0009] Furthermore, an elastic buffer layer is fixedly installed on the inner wall of both the placement slot and the support hole.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figures 1-5 ,in, Figure 1 A schematic diagram of the structure of the multi-layer stacked test tube rack provided by this utility model; Figure 2 This is a partial cross-sectional plan view of the placement plate in this utility model; Figure 3 for Figure 2 The diagram shows an enlarged view of part A. Figure 4 This is a schematic diagram of the connection structure between the placement plate and the side guard in this utility model; Figure 5 This is a schematic diagram of the structure of multiple placement plates in a stacked state in this utility model.

[0017] The multi-layer stackable test tube rack includes: a placement plate 1 and two side rails 2 fixedly installed on the top of the placement plate 1. The placement plate 1 and the two side rails 2 form a rack unit. Multiple placement slots 3 are provided on the top of the placement plate 1. A common support plate 4 is fixedly installed on the side of the two side rails 2 that are close to each other. Multiple support holes 5 are provided on the support plate 4. The multiple placement slots 3 are respectively adapted to the multiple support holes 5. When placing test tubes, the test tubes first pass through the support holes 5 and then into the placement slots 3. An elastic buffer layer made of rubber is fixedly installed on the inner walls of both the placement slots 3 and the support holes 5 to protect the test tubes. To facilitate stacking and assembly, four guide holes 6 are provided on the placement plate 1, and protruding plates 7 are fixedly installed on the outer walls of both sides of the side rails 2. Two guide posts 8 are fixedly installed on the top of each of the two protruding plates 7. Four guide holes 6 are adapted to the four guide posts 8 respectively. The insertion between the guide holes 6 and the guide posts 8 can ensure the installation accuracy. Two assembly ports 9 are opened on the placement plate 1. Restriction ports 10 are opened on both sides of the placement plate 1. The two restriction ports 10 are connected to the two assembly ports 9 respectively. The top of each of the two protruding plates 7 is fixedly installed with an elastic mounting base 11 made of spring steel, which has good deformation and recovery performance. The two elastic mounting bases 11 are fixedly installed with locking strips 12 on the side away from each other. The two locking strips 12 are adapted to the two restriction ports 10 respectively. Through the locking effect between the two, the assembly between the upper and lower shelf units is relatively stable.

[0018] In this embodiment, to facilitate the disassembly of the two shelf units, square sliding columns 13 are fixedly installed on the opposite sides of the two side blocks 2. Connecting plates 14 are slidably installed on the two square sliding columns 13. Connecting folding strips 15 are fixedly installed on the opposite sides of the two connecting plates 14. Pushing pieces 16 are fixedly installed on the opposite sides of the two connecting folding strips 15. The two pushing pieces 16 are respectively adapted to the two limiting sockets 10. Return springs 17 are sleeved on the two square sliding columns 13. The opposite ends of the two return springs 17 are fixedly connected to the two side blocks 2. The opposite ends of the two return springs 17 are fixedly connected to the two connecting plates 14. Operating ears are fixedly installed on the top of the two connecting plates 14. During operation, by pressing the two operating ears, the pushing pieces 16 push the locking strip 12 out of the limiting socket 10, thereby achieving quick disassembly.

[0019] In this embodiment, to improve the ease of assembly, the bottom edges of the two assembly ports 9 that are far apart from each other are both set as bevels, and the tops of the two locking strips 12 are both wedge-shaped. The locking strips 12 are adapted to the bevels. During assembly, simply press down to deform the elastic mounting base 11 by utilizing the cooperation between the locking strips 12 and the bevels. After the upper placement plate 1 contacts the lower side block 2, the elastic mounting base 11 springs back and automatically brings the locking strips 12 into the limiting insertion port 10, thereby completing the assembly without any additional operations.

[0020] The working principle of the multi-layer stacked test tube rack provided by this utility model is as follows: When using it, select the appropriate number of placement plates 1 according to the number of test tubes to be placed; Then, starting from the bottommost placement plate 1, take out another placement plate 1 and place it on top of the previous placement plate 1. Align the guide hole 6 on it with the guide post 8 on the lower side block 2 and insert it. During the insertion process, the locking strip 12 on the lower side block 2 will enter the assembly port 9 on the upper placement plate 1. Through the cooperation of the locking strip 12 and the bottom slope of the assembly port 9, the elastic mounting seat 11 will deform. When the upper placement plate 1 contacts the lower side block 2, the locking strip 12 corresponds to the limiting insertion port 10. The deformed elastic mounting seat 11 rebounds and automatically locks the locking strip 12 into the limiting insertion port 10, thereby realizing the stacking of two placement plates 1. After that, the remaining placement plates 1 can be stacked and assembled in the same way as above. After assembly, the test tubes that need to be placed can be passed through the corresponding support holes 5 in sequence and placed in the corresponding placement slots 3. Then the test tubes can be taken out and used directly. When removing the stacked placement plates 1, start from any height of placement plate 1 and press the corresponding operating ears in the direction of mutual approach to push the two corresponding push tabs 16 into the corresponding limiting slots 10. When the push tabs 16 contact the corresponding locking strips 12, they will push them out of the limiting slots 10. Then, simply lift them up to separate the two adjacent placement plates 1. This operation can be repeated until all are removed.

[0021] Compared with related technologies, the multi-layer stacked test tube rack provided by this utility model has the following advantages: I. This utility model, by setting multiple detachable shelf units, allows for flexible adjustment of the number of test tube racks according to the number of test tubes. When the number of test tubes is small, fewer shelf units can be used to reduce space occupation; when the number of test tubes is large, the number of shelf units can be increased to improve space utilization and provide high flexibility in use. Second, when assembling the placement plate 1, this utility model can quickly assemble it by means of the elasticity of the elastic mounting base 11 and the cooperation between the locking strip 12 and the bottom slope of the assembly port 9. The connection is stable and it is not easy to shake or separate during transportation, which improves the safety of the test tube rack. At the same time, when disassembling, it is only necessary to press the connecting plate 14 to release the insertion state between the locking strip 12 and the limiting insertion port 10. Disassembly is quick and convenient to use.
