Description

Technical Field

[0001] The utility model relates to the technical field of biological experiments, in particular to a test tube transport box. Background Art

[0002] In the process of biological experiments, test tubes are indispensable experimental tools. However, the existing test tube transport box usually only inserts the test tubes into the test tube rack inside the box. This simple fixing method cannot effectively reduce shock during the transport process.

[0003] In addition, some test tube transport boxes only press the top of the test tube, while the bottom of the test tube is in hard contact with the bottom of the test tube rack. Although this fixing method can fix the test tube to a certain extent, during the transportation process, due to the hard contact between the bottom of the test tube and the bottom of the test tube rack, friction and vibration are easily generated, further increasing the risk of damage to the test tube;

[0004] In addition, the existing test tube transport box is also inconvenient in taking out the test tube. Usually, the user needs to manually pull the test tube out of the test tube rack. This operation method is not only inefficient, but also the hands come into contact with the test tube mouth, which is easy to be contaminated. Therefore, we propose a test tube transport box.

[0006] As a preferred technical solution of the utility model, the fixing assembly is composed of a pressing plate, a telescopic rod and a compression spring. There are four telescopic rods, which are arranged in an equidistant circular array on the inner top of the box cover. A pressing plate is fixedly installed at the bottom of the telescopic end of the telescopic rod, and the diameter of the pressing plate is smaller than the inner diameter of the box body. Compression springs are respectively set on the outer side of the telescopic rod, and the upper and lower ends of the compression springs are respectively fixedly connected to the inner top of the box cover and the top surface of the pressing plate. Since the diameter of the pressing plate is smaller than the inner diameter of the box body, when the box cover is installed on the top of the box body, the elastic force of the compression spring causes the pressing plate to push and fix the test tube, which effectively prevents the shaking of the test tube during transportation and ensures the stability and safety of the test tube.

[0007] As a preferred technical solution of the utility model, silicone rings are fixedly installed on the inner sides of the test tube insertion holes on the tray, and the inner surfaces of the silicone rings are in active contact with the outer surfaces of the test tubes.

The movable contact increases the friction between the test tube 8 and the test tube insertion hole. The silicone ring 7 can also provide buffer protection for the outer side of the test tube 8, effectively avoiding hard contact between the test tube 8 and the test tube insertion hole on the rack 6. The bottom center of the rack 6 is fixedly connected to the rotating assembly 5 arranged at the inner bottom of the box body 1. The rotating assembly 5 is composed of a motor 51, a fixed plate 52, a worm 53, a rotating shaft 54 ​​and a worm gear 55. The rotating shaft 54 ​​is arranged inside the box body 1.

The output end of the controller 3 is electrically connected to the input end of the motor 51 and the electric push rod 18, and the input end of the controller 3 is electrically connected to the output end of the mobile power supply 13.

[0020] The working principle of the utility model is as follows: when in use, first grasp the handle 9 and rotate the box cover 2, so as to remove the box cover 2 from the box body 1. After the box cover 2 is opened, the test tubes 8 are respectively inserted into the test tube insertion holes on the tray rack 6, and the dense-pore elastic net 17 on the bracket 16 elastically supports the bottom of the test tube 8. This design provides a shock-absorbing function for the bottom of the test tube 8, effectively preventing the impact of vibration that may be generated during transportation on the test tube 8. Subsequently, the box cover 2 is threadedly installed on the top of the box body 1. Since the diameter of the pressing plate 10 is smaller than the inner diameter of the box body 1, when the box cover 2 is installed on the top of the box body 1, the pressing plate 10 pushes the top of the test tube 8 downward under the action of the compression spring 12. Under the coordinated action of the pressing plate 10 and the dense-pore elastic net 17, the test tube 8 is firmly fixed in the test tube insertion hole, avoiding the test tube from being damaged during transportation. 8 shakes in the test tube insertion hole; when taking out the test tube 8, first open the box cover 2, then start the electric push rod 18 through the controller 3, so that its telescopic end drives the spherical top block 19 to push the bottom of the dense-pore elastic net 17, thereby pushing up the corresponding test tube 8 above it, and the test tube 8 moves upward along the test tube insertion hole on the rack 6. Due to the elasticity of the dense-pore elastic net 17, the pushing effect of the spherical top block 19 will make the corresponding test tube 8 above move upward, so that it is convenient for the user to take it. Then, when taking out other test tubes 8 on the rack 6, the motor 51 can be started through the controller 3, and the output shaft of the motor 51 drives the worm 53 to rotate. Since the worm 53 is meshed with the teeth on the worm gear 55, the worm gear 55 drives the rotating shaft 54 ​​and the rack 6 to rotate until another test tube 8 on the rack 6 moves to the top of the spherical top block 19.
