Description

Technical Field

[0001] This utility model relates to the field of tray technology, specifically a rotating tray for a constant temperature incubator. Background Technology

[0002] Incubators are crucial equipment for the isothermal culture of cells, microorganisms, or small biological models in biological, pharmaceutical, and agricultural research and production. During the culture process, to ensure a uniform culture environment, a rotating tray is often used, allowing the culture samples to rotate slowly within the chamber, thus ensuring even heating and contact with the gaseous environment. These culture samples are typically placed in petri dishes or similar containers, and then placed on the tray body of the rotating tray for incubation.

[0003] However, the distance between the rotating tray and the pressure cap on the top of the existing constant temperature incubator is not adjustable, which means that the pressure cap cannot be adapted to the thickness of the material. It cannot stably limit the placement of culture containers or samples of different heights. Taller materials cannot be placed in, while shorter materials have wasted space above and cannot be effectively compressed, which limits the flexibility and versatility of the equipment.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1-4 As shown, this utility model provides a technical solution: A rotating tray for a constant temperature incubator includes a base 1 with a vertical rotating tube 2 fixedly connected to its top. Several tray bodies 3 are fixedly connected at equal intervals along the length of the outer wall of the rotating tube 2. Several air holes 14 are evenly distributed on the inner bottom wall of each tray body 3. A pressure cap 4 is movably sleeved on the outside of the rotating tube 2 and located above the tray bodies 3. The pressure cap 4 also has several air holes 13. An adjusting mechanism is located inside the rotating tube 2 and is drively connected to the pressure cap 4. The adjusting mechanism includes a lifting groove 5 formed in the middle of the rotating tube 2 and a lead screw 6 rotatably connected to the lifting groove 5 via a bearing. The external thread of the screw 6 is connected to a sliding nut 7. The top of the screw 6 is fixedly connected to a rotating handle 8. The adjustment mechanism also includes symmetrical grooves 9 at both ends of the rotating tube 2, and sliders 10 symmetrically fixedly connected to the outer walls at both ends of the sliding nut 7. The sliders 10 slide with the grooves 9. The middle of the pressure cover 4 is provided with a movable hole 11. The ends of the two sliders 10 away from the sliding nut 7 are fixedly connected to the two side walls of the movable hole 11 respectively. The upper and lower ends of the sliding nut 7 are fixedly connected to corrugated telescopic sleeves 12. The ends of the two corrugated telescopic sleeves 12 away from the sliding nut 7 are fixedly connected to the inner top wall and inner bottom wall of the lifting groove 5 respectively. In this embodiment, the height of the cover plate is adjusted by the cooperation of the lead screw 6 and the sliding nut 7, so that it can be tightly pressed against the upper surface of materials of different thicknesses, thus solving the problem that the existing pressure cover 4 cannot adapt to the material thickness.

[0012] Working principle: When the material is placed inside the tray body 3, in order to adapt to different material thicknesses and limit the upper surface of the material, the rotating shaft 8 drives the lead screw 6 to rotate in the lifting groove 5, which in turn drives the sliding nut 7 to move downward along the lead screw 6. The sliding nut 7 drives the sliders 10 fixed at both ends to slide downward synchronously in the sliding groove 9. Thus, the sliders 10 connected to the two side walls of the movable hole 11 drive the pressure cover 4 to descend stably along the outside of the rotating tube 2 until the lower surface of the pressure cover 4 abuts against the upper end of the material. The adjusting mechanism realizes the pressure cover 4 to press or cover materials of different thicknesses. During this process, the corrugated telescopic sleeve 12 fixed to the upper and lower ends of the sliding nut 7 extends and retracts accordingly, always sealing the opening of the lifting groove 5, effectively preventing external debris from entering the lifting groove 5. After the adjustment is completed, the airflow in the constant temperature incubator can still form a circulation through the air hole 13 of the pressure cover 4 that has been pressed onto the material and the air hole 24 at the bottom of the tray body 3, which ensures the uniformity and stability of the cultivation environment while fixing the position of the material.

[0013] In the specific implementation of this technical solution, the base 1 is used to be fixedly connected to a conventionally installed rotary drive output end (such as a drive motor shaft, transmission gear, or drive pulley) inside the constant temperature incubator. Although such rotary drive components are not described in detail in the technical solution, they are well-known mature structures in the field of constant temperature incubators for providing rotational power. Their specific types and connection methods are conventionally selected and implemented by those skilled in the art based on the actual chamber structure and load requirements. By being fixedly connected to the drive output end, the base 1 transmits external power to the rotating tube 2, thereby driving the entire tray assembly to rotate. This connection is the basis for realizing the tray's revolution function, but its specific form does not affect the implementation of the core innovation point of this solution (i.e., the adjustable distance cover mechanism), and both fall within the reasonable extension range of this technical solution.

[0014] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
