Description

Technical Field

[0001] The utility model relates to the technical field of incubators, in particular to a stem cell directional diffusion incubation device. Background Art

[0002] An incubator, also known as a cultivation box, is a temperature-controllable box device mainly used to cultivate microorganisms, plant and animal cells. Some have a two-way temperature control system for refrigeration and heating. It is a basic experimental equipment for scientific research departments such as biology, agriculture, medicine, and environmental protection, and is widely used in constant temperature culture, constant temperature reaction and other experiments.

[0003] An existing patent (publication number: CN218345471U) discloses a stem cell directional diffusion cultivation device, which allows multiple cultivation box bodies to be stacked by setting a stacking device, so that users can carry multiple at a time. The specific operation steps are to pull the connecting plate upward to drive the second spring to stretch, so that the upper end of the connecting plate at the bottom can be inserted into the interior of the locking groove at the upper end, and then the bolt group is inserted into the interior of the socket to fix the two, so as to facilitate the locking between the cultivation box bodies, reduce the possibility of them falling, and ensure more stability when moving.

[0004] However, the equipment introduced above still has certain shortcomings. In the installation operation of the two groups of stem cell directional diffusion cultivation devices, it is first necessary to stretch the connecting plate. In this process, the spring stretching needs to reach a certain tensile strength, which has certain requirements on the strength of the operator and increases the difficulty of the operation. Then the stretched connecting plate must be accurately docked and inserted into the locking groove at the upper end. This step requires high operating precision and patience. A slight deviation may lead to unsuccessful docking. Finally, a bolt group must be inserted into the socket to fix the two. The whole process is relatively cumbersome and needs to be repeated many times. When disassembling and assembling, it is also necessary to repeat the above steps in reverse. For the docking and disassembly of the upper and lower groups of stem cell culture boxes, not only the operating steps are cumbersome and time-consuming, but also a great deal of physical strength of the staff is consumed, which reduces work efficiency, brings inconvenience to actual use, and to a certain extent affects the convenience and practicality of the device in actual application.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] A stem cell directed diffusion cultivation device, such as Figure 1 - Figure 4 As shown, it comprises a stem cell culture box 1, two groups of disassembly and assembly components 2 are fixedly connected at diagonal positions on the lower surface of the stem cell culture box 1, and a movable cavity 101 is opened at the bottom end of the stem cell culture box 1;

[0031] The disassembly assembly 2 includes a second pin 21 fixedly connected to the lower surface of the stem cell culture box 1, a rotating shaft 22 is rotatably connected at the middle position of the second pin 21, and the rotating shaft 22 extends upward to the inside of the active cavity 101, a worm gear 23 is fixedly connected at the center position of the rotating shaft 22, a screw rod 222 is fixedly connected to the outer wall of the rotating shaft 22 below the worm gear 23, a threaded sleeve 252 is threadedly connected to the outer wall of the screw rod 222, a pressing block 25 is fixedly connected to the bottom end of the outer wall of the threaded sleeve 252, and the lower surface of the pressing block 25 is fixedly connected to the outer wall of the screw rod 222. A limit rod 251 is fixedly connected to the center of the surface, and the bottom end of the limit rod 251 extends to the inner wall of the second pin 21. The outer wall of the second pin 21 is slidably sleeved with multiple groups of clamping rods 26 in an equiangular annular array. A roller 262 is rotatably installed on the outer wall of one end of the clamping rod 26 close to the pressure block 25, and the roller 262 is in contact with the pressure block 25. A spring 27 is sleeved on the outer wall of the clamping rod 26. The inner wall of the movable cavity 101 is rotatably connected to the rotating rod 24. The outer wall of the rotating rod 24 is fixedly connected to a worm 241, and the worm 241 is meshed with the worm wheel 23.

[0032] The first pin 13 and the second pin 21 are first aligned with the first docking hole 11 and the second docking hole 12 and inserted therein, and then the torsion block 242 is twisted to drive the rotating rod 24 and the worm 241 to rotate, and then the worm 241 engages with the worm wheel 23, so that the rotating shaft 22 and the screw rod 222 rotate. Then, as the screw rod 222 rotates, the threaded sleeve 252 is driven to move downward, and the threaded sleeve moves downward while driving the pressing block 25 and the limiting rod 251 downward. The pressing block 25 squeezes multiple groups of rollers 262 during the downward movement. After the rollers 262 are squeezed, the multiple groups of clamping rods 26 are driven to extend outward and insert into the corresponding jacks, thereby finally realizing the rapid docking of the upper and lower groups of stem cell culture boxes 1.
