[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figure 1-Figure 5As shown, the utility model provides a constant temperature box for stem cell samples, including an incubator 1, a door 2 is hinged on the side wall of the incubator 1, a temperature sensor 3 is fixedly connected to the inner wall of the incubator 1, an electric heating pipe 4 is fixedly connected to the inner wall of the incubator 1, a controller 5 is fixedly connected to the side wall of the incubator 1, the temperature sensor 3 and the electric heating pipe 4 are both electrically connected to the controller 5, and an adjustment structure 6 is provided on the inner wall of the incubator 1. The adjustment structure 6 includes a support plate 601, and the support plate 601 is fixedly connected to the incubator 1 The surface of the support plate 601 is slidably connected to several splints 602, the inner wall of the splint 602 is slidably connected to a strip plate 603, the surface of the strip plate 603 is fixedly connected to a tray 604, the surface of the tray 604 is provided with several through holes 605, the lower surface of the splint 602 is fixedly connected to a rectangular plate 606, a pin 607 slides through the rectangular plate 606, and the surface of the support plate 601 is provided with several sockets 608, and the size of the pin 607 is adapted to the size of the socket 608.

[0030] like Figure 2-Figure 5 As shown, the vertical cross-section of the through hole 605 is "T"-shaped. The through hole 605 with a vertical cross-section of "T" shape can improve the ventilation effect of the tray 604 and ensure that hot air can flow upward normally. The arc surface of the latch 607 is covered with a spring 609. The two ends of the spring 609 are fixedly connected to the rectangular plate 606 and the latch 607 respectively. When the spring 609 contracts, the latch 607 will be inserted into the socket 608 with the help of the elastic force of the spring 609. The surface of the splint 602 is provided with an oblique groove 610, which is convenient for the strip plate 60 3 slides into the clamping plate 602. The clamping plate 602 is internally threaded with a bolt 611. A clearance groove 612 is provided on the surface of the strip plate 603. The size of the bolt 611 matches the size of the clearance groove 612. The clearance groove 612 cooperates with the bolt 611 to limit the sliding distance of the strip plate 603 along the clamping plate 602, thereby preventing the strip plate 603 from losing contact with the clamping plate 602. A handle 613 is fixedly connected to the side wall of the tray 604. Pulling the handle 613 will drive the tray 604 to move.

[0031] The overall working principle is as follows: when culturing stem cell samples, the culture dish is placed in the tray 604, and then the air in the incubator 1 is heated by the electric heating tube 4. At the same time, the temperature sensor 3 monitors the temperature in the incubator 1 in real time. The controller 5 controls the working state of the electric heating tube 4 according to the monitoring result to keep the temperature in the incubator 1 constant. The through hole 605 with a vertical cross section of "T" shape can improve the ventilation effect of the tray 604 and ensure that the hot air can flow upward normally. When the distance between the trays 604 needs to be adjusted, the temperature in the incubator 1 can be adjusted. When the distance is set, the bolt 611 is turned, and the bolt 611 moves upward with the help of the thread. When the bolt 611 moves to a suitable position, the handle 613 is pulled, and the handle 613 drives the tray 604 to move. The tray 604 drives the strip plate 603 to slide out from the inner wall of the clamping plate 602, and then the latch 607 is pulled. The latch 607 stretches the spring 609 and disengages the socket 608. Then, the clamping plate 602 is slid along the surface of the support plate 601. When the clamping plate 602 slides to a suitable position, the latch 607 is released. 07, the latch 607 will be inserted into the socket 608 with the help of the elastic force of the spring 609. At this time, the socket 608 reaches the position of the latch 607, thereby limiting the position of the clamp 602. Then, the other corresponding clamp 602 is adjusted to the same height, and then the removed tray 604 is moved. The inclined groove 610 facilitates the sliding of the strip plate 603 into the clamp 602. At this time, the clamp 602 can limit the position of the strip plate 603, thereby limiting the position of the tray 604, thereby achieving the adjustment of the tray 604. 04 spacing, the purpose of improving the utilization efficiency of the internal space of the incubator 1, and then rotating the bolt 611 in the opposite direction, the bolt 611 will move downward and rest against the inner wall of the paving groove 612. At this time, the paving groove 612 and the bolt 611 can cooperate to limit the sliding distance of the strip plate 603 along the splint 602, and prevent the strip plate 603 from being out of contact with the splint 602. When taking out the culture dish placed on the tray 604, the tray 604 can be pulled out of the incubator 1 for a certain distance, which is convenient for taking.
