[0003] When some existing biochemical incubators are in use, in order to facilitate the placement of culture dishes, a slidable placement plate needs to be arranged inside the incubator, so as to facilitate the placement and taking of culture dishes inside the incubator. However, since the placement plate slides on the inner wall of the incubator, due to the lack of fixation, when the incubator moves, the placement plate will move, and thus the placement plate cannot be fixed well.

[0004] In view of the above problems, for this reason, an internal positioning mechanism of a biochemical incubator is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide an internal positioning mechanism of a biochemical incubator, which can solve the problems in the background art.

[0024] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0025] Please refer to Figures 1-4, the present utility model provides a technical solution: an internal positioning mechanism of a biochemical incubator, including a biochemical incubator body 1. Two fixing blocks 7 are fixedly installed inside the biochemical incubator body 1. Slideways 8 are opened on the opposite sides of the two fixing blocks 7. A placement plate 4 is slidably connected inside the two slideways 8. A placement hopper 3 is fixedly installed on the top of the placement plate 4. Slide columns 5 are slidably connected inside the two fixing blocks 7. Rotating wheels 6 are rotatably connected to one ends of the two slide columns 5. Moving plates 13 are fixedly installed at the ends of the two slide columns 5 extending into the fixing blocks 7. First elastic springs 15 are fixedly installed inside the two fixing blocks 7. One ends of the two first elastic springs 15 close to the two moving plates 13 are fixedly connected to the two moving plates 13 respectively. Extrusion grooves 14 are opened on the surfaces of the two moving plates 13. One side of the extrusion groove 14 is inclined. A circular hole 10 communicating with the slideway 8 is opened inside the fixing block 7. A first fixing rod 9 is slidably connected inside the circular hole 10. The upper end of the first fixing rod 9 is conical. A sliding head 12 is fixedly installed at the lower end of the first fixing rod 9. The sliding head 12 contacts the surface of the moving plate 13.

The lower end of the return spring 11 is fixedly connected to the top of the sliding head 12.

[0026] When the biochemical incubator body 1 is opened, the door will no longer squeeze the rotating wheel 6, so that the slide column 5 and the moving plate 13 are reset by the elastic force of the first elastic spring 15. Then the moving plate 13 slides inside the fixing block 7, so that the sliding head 12 slides along the inclined surface of the extrusion groove 14. Then the moving plate 13 no longer squeezes the sliding head 12, and the sliding head 12 and the first fixing rod 9 are reset by the elastic force of the return spring 11. Then the sliding head 12 enters the inside of the extrusion groove 14, and the first fixing rod 9 contracts into the inside of the circular hole 10. When the sealing door is closed, it will squeeze the rotating wheel 6, so that the slide column 5 slides into the fixing block 7. Then the inclined surface inside the extrusion groove 14 squeezes the sliding head 12, and then squeezes the return spring 11, so that the first fixing rod 9 moves to the outside of the circular hole 10 and squeezes the placement plate 4 to fix it. Then it is convenient to fix the placement plate 4 and the placement hopper 3, prevent the placement hopper 3 from shaking inside the biochemical incubator body 1, improve the stability of the placement hopper 3 during use, avoid the placement hopper 3 from moving when transporting the biochemical incubator body 1, and at the same time facilitate the positioning of the placement hopper 3.

[0027] Inside the placing hopper 3, two fixing pieces 21 are fixedly installed. Inside both of the two fixing pieces 21, support sliding rods 19 are slidably connected. Both of the two support sliding rods 19 slidably penetrate through the placing hopper 3 and extend to the outside of the placing hopper 3. At the upper ends of the two support sliding rods 19, a sealing plate 2 is fixedly installed. On both of the two support sliding rods 19, second elastic springs 20 are movably sleeved. The upper ends of the two second elastic springs 20 are fixedly connected to the bottom of the sealing plate 2. The lower ends of the two second elastic springs 20 are respectively fixedly connected to the two fixing pieces 21. Inside the placing hopper 3, two sliding blocking blocks 16 are slidably connected. The upper ends of the two sliding blocking blocks 16 are inclined. Inside the placing hopper 3, two second fixing rods 18 are fixedly installed. The two sliding blocking blocks 16 are respectively slidably connected on the surfaces of the two second fixing rods 18. On both of the two second fixing rods 18, springs 17 are movably sleeved. The opposite ends of the two springs 17 are respectively fixedly connected to the two sliding blocking blocks 16. The opposite ends of the two springs 17 are respectively fixedly connected to the two second fixing rods 18.

[0028] Make the two sliding blocking blocks 16 move away from each other, and then make the two sliding blocking blocks 16 slide outwards inside the placing hopper 3. Then make the two sliding blocking blocks 16 slide on the two second fixing rods 18 respectively, and stretch the two springs 17. At the same time, make the protrusions at the upper ends of the two sliding blocking blocks 16 no longer block the sealing plate 2. Then make the sealing plate 2 move upwards through the elastic force of the two second elastic springs 20, make the two support sliding rods 19 slide inside the two fixing pieces 21 and the placing hopper 3. Then make the sealing plate 2 no longer seal the placing hopper 3. Then open the placing hopper 3, which is convenient for squeezing and fixing the culture dish inside the placing hopper 3, and then prevent the culture dish from sliding inside the placing hopper 3, and then improve the fixing effect on the culture dish.

[0029] Working principle:

[0030] When the biochemical incubator body 1 is opened, the door will no longer squeeze the rotating wheel 6. Then the sliding column 5 and the moving plate 13 are reset through the elastic force of the first elastic spring 15. Then the moving plate 13 slides inside the fixed block 7. Then the sliding head 12 slides along the inclined surface of the extrusion groove 14. Then the moving plate 13 no longer squeezes the sliding head 12. The sliding head 12 and the first fixing rod 9 are reset through the elastic force of the reset spring 11. Then the sliding head 12 enters into the extrusion groove 14. Then the first fixing rod 9 retracts into the circular hole 10. When closing the sealing door, it will squeeze the rotating wheel 6. Then the sliding column 5 slides into the fixed block 7. Then the inclined surface inside the extrusion groove 14 squeezes the sliding head 12, and then squeezes the reset spring 11. Then the first fixing rod 9 moves to the outside of the circular hole 10 to squeeze and fix the placing plate 4, which is convenient for fixing the placing plate 4 and the placing hopper 3.

[0031] Move the two sliding stoppers 16 away from each other, so that the two sliding stoppers 16 slide outward inside the placing hopper 3, and then the two sliding stoppers 16 slide on the two second fixing rods 18 respectively, and stretch the two springs 17. At the same time, the protrusions at the upper ends of the two sliding stoppers 16 no longer block the sealing plate 2, so that the sealing plate 2 moves upward by the elastic force of the two second elastic springs 20, and the two support sliding rods 19 slide inside the two fixing pieces 21 and the placing hopper 3. Then the sealing plate 2 no longer seals the placing hopper 3, and the placing hopper 3 is opened.
