Description

Technical Field

[0001] The utility model belongs to the technical field of carbon dioxide incubators, in particular to a carbon dioxide incubator which is convenient for taking and placing culture dishes. Background Art

[0002] The carbon dioxide incubator is a device for culturing cells. It cultivates cells and tissues by simulating a growth environment similar to that of cells and tissues in organisms inside the incubator. It is widely used in the research and production of medicine, immunology, genetics, microbiology, agricultural science, and pharmacology, and has become one of the most commonly used conventional instruments in laboratories in the above fields.

[0003] The interior of the carbon dioxide incubator is usually provided with a plurality of shelves for holding culture dishes. The shelves inside the existing carbon dioxide incubator are mostly fixed inside the incubator. For the culture dishes near the inner side of the incubator, it is inconvenient to place and take the culture dishes because they are blocked by the external culture dishes and the depth of the inner cavity of the incubator.

[0004] Publication No. "CN220183289U" discloses "a carbon dioxide incubator". By pushing the push plate to slide along the inside of the slide, the pull ropes at both ends can slide along the inside of the through hole, thereby pulling the plug plates at both ends into the groove and compressing the first spring to make it elastic. Then the shelf plate can be supported for lifting and lowering adjustment. After the adjustment is completed, the push plate can be released, and the first spring with elastic force at both ends will push the plug plate to be inserted into the socket, thereby firmly fixing the position of the shelf plate. The distance between each shelf plate can be adjusted as needed for easy use.

[0005] The above technical solution still has the following disadvantages during the specific implementation process:

[0006] Since the position of the socket is fixed, the distance between two adjacent shelf boards is still fixed, and the distance is easily larger or smaller, which is inconvenient for taking and placing the culture dishes. At the same time, when taking and placing the culture dishes before and after cultivation, the shelf boards of each layer need to be taken out one by one, which is troublesome and inconvenient for quick taking and placing of the culture dishes.

[0007] In view of the above problems, we propose a carbon dioxide incubator that is convenient for taking and placing culture dishes. Utility Model Content

[0031] The placement plate 8 is convenient for placing the culture dish. The movable plate 6 cooperates with the screw rod 5 and the fixed rod 4, the threaded cooperation between the threaded sleeve 7 and the screw rod 5, and the rotation connection between the upper end of the threaded sleeve 7 and the movable plate 6, which is convenient for flexibly adjusting the up and down rotation of the threaded sleeve 7. The up and down rotation of the threaded sleeve 7 drives the up and down movement of the movable plate 6, and then drives the placement plate 8 to move in the vertical direction, so as to achieve the purpose of flexibly adjusting the distance between two adjacent placement plates 8, and solves the problem that the distance between two adjacent shelf plates is still fixed due to the fixed position of the socket in the prior art, which is prone to a large or small distance, and is inconvenient for taking and placing the culture dish.

[0032] Under the action of the rotating shaft between the strip plate 12 and the fixed plate 11, combined with the elastic action of the extrusion spring 15, it is convenient to squeeze the rear end of the strip plate 12 downward, thereby driving the insert block 14 to be inserted into the corresponding slot 13, which facilitates the limiting fixation of the placement plate 8 and ensures the stability of the placement plate 8 and the culture dish placed thereon;

[0033] The sliding assembly allows for flexible adjustment of the forward and backward movement of the placement plate 8, allowing for easy placement of the culture dishes on the designated placement plate 8; at the same time, the moving assembly allows for flexible adjustment of the movement and fixation of the bottom plate 2, allowing for synchronous movement of multiple placement plates 8 to the outside of the box body 1, making it convenient for the placement of culture dishes. This solves the problem in the prior art that when placing and taking culture dishes before and after culture, the shelf plates of each layer need to be taken out one by one, which is cumbersome to operate and inconvenient for placing and taking culture dishes.

[0034] The sliding assembly includes a strip groove 9 and a slider 10. Two strip grooves 9 are relatively opened on the movable plate 6. The slider 10 is slidably set inside the strip groove 9, and two adjacent sliders 10 are relatively fixed on the bottom rear side of the placement plate 8. A pull rod 16 is fixed to the front end of the strip plate 12. The sliding cooperation between the slider 10 and the strip groove 9 facilitates the movement of the placement plate 8. Combined with the pull rod 16 and the strip plate 12, it is convenient to pull the placement plate 8 to move forward and backward.

[0035] The moving assembly includes a guide groove 22, a guide rod 23, a guide block 24 and a limit assembly. The guide groove 22 is opened at the inner bottom of the box body 1, the guide rod 23 is fixed inside the guide groove 22, the guide block 24 is slidably sleeved on the guide rod 23, and the guide block 24 is fixed to the rear side of the bottom of the bottom plate 2. A handle is fixed at the front end of the bottom plate 2. The sliding cooperation between the guide block 24 and the guide rod 23 facilitates the adjustment of the movement of the bottom plate 2.

[0036] The limiting assembly includes a baffle 18, a paddle 19, a vertical rod 20 and a return spring 21. The vertical rod 20 is fixed to the front side of the bottom of the box body 1, and a limiting plate is fixed to the bottom end of the vertical rod 20. The paddle 19 is slidably mounted on the vertical rod 20. The return spring 21 is mounted on the outside of the vertical rod 20, and the two ends of the return spring 21 are respectively fixedly connected to the paddle 19 and the limiting plate. Both baffles 18 are fixed on the paddle 19. Two rectangular grooves run through the bottom of the box body 1. The baffle 18 and the rectangular grooves are movably matched. Two notches are relatively opened at the rear end of the bottom plate 2. The baffle 18 cooperates with the front end surface and the notch of the bottom plate 2. A pull ring is fixed to one side of the bottom of the paddle 19.

[0037] A number of protrusions 17 are fixed on the lower side of the outer surface of the threaded sleeve 7, a box door 25 is movably installed on the front side of the box body 1, and a number of through holes are penetrated on the movable plate 6, which cooperate with the screw rod 5 and the fixed rod 4. The friction force of the outer wall of the threaded sleeve 7 is increased by the protrusions 17, which facilitates the adjustment of the up and down movement of the threaded sleeve 7. The cooperation between the through holes, the screw rod 5 and the fixed rod 4 enables the movable plate 6 to move up and down.

[0038] A plurality of grooves are provided on both sides of the box body 1, and connecting blocks 28 are fixed to the front sides of the left and right surfaces of the bottom plate 2 and the U-shaped plate 3. A telescopic rod 27 is connected between the connecting block 28 and the inner wall of the groove, and the telescopic rod 27 further limits and guides the movement of the bottom plate 2 and the U-shaped plate 3.

[0039] Embodiment 1:

[0040] like Figure 7-10 As shown, before and after the culture, when all the culture dishes need to be taken and placed, the pull ring is used to pull the paddle plate 19 downward, and the reset spring 21 is squeezed, and at the same time, the two baffles 18 are driven to move downward along the rectangular groove, away from the bottom plate 2;

[0041] Secondly, under the sliding cooperation between the guide block 24 and the guide rod 23, the bottom plate 2 is pulled to move toward the outside of the box body 1 through the handle on the front side of the bottom plate 2 until the guide block 24 moves to the frontmost side of the guide groove 22. At this time, the pull ring is released, and the paddle plate 19 is pressed upward under the elastic action of the reset spring 21, thereby driving the baffle plate 18 to pass through the rectangular groove and get stuck in the notch on the rear side of the bottom plate 2, so as to limit and fix the bottom plate 2. Finally, the staff takes and places all the culture dishes.

[0042] After all the culture dishes are taken and placed, the above steps are reversed to move the bottom plate 2 completely into the box body 1. Under the combined action of the reset spring 21, the paddle plate 19 and the upright rod 20, the baffle plate 18 is driven to move to abut against the front end surface of the bottom plate 2, and the front side of the bottom plate 2 is limited and fixed, thereby ensuring the stability of the bottom plate 2, and then ensuring the stability of the plurality of placement plates 8 and the culture dishes placed on the placement plates 8, thereby solving the problem in the prior art that when taking and placing the culture dishes before and after culturing, the shelf plates of each layer need to be taken out one by one, which is troublesome to operate and inconvenient to take and place the culture dishes.

[0043] When it is necessary to take or place the culture dish on the designated placement plate 8, first press the pull rod 16 downward, and under the action of the rotating shaft between the strip plate 12 and the fixed plate 11, the inner end of the strip plate 12 is tilted upward, and the squeezing spring 15 is compressed until the plug block 14 is driven to disengage from the slot 13 on the rear side upward, combined with the sliding cooperation between the slider 10 and the strip groove 9, and the pull rod 16 is pulled to the front side, driving the placement plate 8 to move to the front side until the slider 10 moves to the frontmost side of the strip groove 9, at this time, the corresponding placement plate 8 is driven to move to the frontmost side, and the pull rod 16 is released. Under the elastic action of the squeezing spring 15, the rear end of the strip plate 12 is squeezed downward, and the plug block 14 is driven to be inserted downward into the front slot 13, so as to limit and fix the placement plate 8, so that the staff can take or place the culture dish on the placement plate 8 conveniently;

[0044] After the culture dish is taken and placed, the operation is reversed, and the slider 10 is adjusted to slide backward until the slider 10 slides to the rear side of the strip groove 9. At this time, under the joint action of the extrusion spring 15 and the strip plate 12, the insert block 14 is driven downward to be inserted into the slot 13 on the rear side, and the placement plate 8 is limited and fixed, thereby ensuring the stability of the placement plate 8.

[0045] Embodiment 2:

[0046] When it is necessary to adjust the distance between two adjacent placement plates 8, under the action of the protrusion 17, the threaded sleeve 7 is rotated so that the threaded sleeve 7 rotates along the direction of the screw rod 5. Combined with the active cooperation of the movable plate 6, the screw rod 5 and the fixed rod 4, the movable plate 6 is driven to move up and down in the vertical direction, and then the corresponding placement plate 8 is driven to move up and down, and flexibly stop at any height, so as to achieve the purpose of flexibly adjusting the distance between adjacent placement plates 8. This solves the problem that in the prior art, the position of the socket is fixed, resulting in the distance between two adjacent shelf plates being still fixed, which is prone to a larger or smaller distance, making it inconvenient to take out and put the culture dish.

[0047] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects.
