[0002] Refrigerators, as a common device for storing refrigerated items, have been widely used in industrial and household applications. Especially in laboratories, refrigerators are indispensable as a low-temperature and constant-temperature storage device. Most existing laboratory refrigerators simply combine a cabinet and a door to form a refrigerated space inside the cabinet, which can be used to store reagent kits at low temperatures.

[0003] However, in order to make full use of the internal space, existing laboratory refrigerators typically store a large number of reagent kits in each compartment. However, when retrieving these kits, especially when accessing them from above, staff cannot observe the contents of the top compartment, making it inconvenient to access the kits stored there. Therefore, a laboratory refrigerator that facilitates the retrieval and storage of reagent kits is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies where it is inconvenient to retrieve reagent kits placed on the top shelf of a refrigerator, this invention provides a laboratory refrigerator that facilitates the retrieval and placement of reagent kits.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a laboratory refrigerator for easy access to reagent kits, comprising a refrigerator body, a refrigerator door hinged to the surface of the refrigerator body, support plates arranged at equal intervals on the inner wall of the refrigerator body, and a placement box fixedly connected to the surface of the support plates, the inner wall of the placement box being inclined, and ball bearings embedded in the inner wall of the placement box.

[0007] As a preferred embodiment of this utility model, both sides of the inner wall of the refrigerator body are fixedly connected with a lower support plate and an upper support plate. The lower support plate has an L-shaped cross-section, and the upper support plate is located above the lower support plate. The two sides of the support plate are respectively located between the two sets of lower support plates and upper support plates.

[0008] As a preferred embodiment of this utility model, the surface of the lower support plate is provided with a slide rail with an L-shaped cross section, and two movable blocks are fixedly connected to the surface of the support plate. The surfaces of the two movable blocks are slidably connected to the inner walls of the two slide rails respectively.

[0009] As a preferred embodiment of this utility model, slide rails are fixedly connected to both sides of the inner wall of the refrigerator body, and sliders are slidably connected to the inner walls of the two slide rails. A connecting groove with a concave cross-section is opened at the bottom of the slider, and a connecting column is fixedly connected to the surface of the support plate. The upper end of the connecting column matches the inner wall of the connecting groove.

[0010] As a preferred embodiment of this utility model, the slider is rotatably connected to a rotating shaft protruding from the slider surface, and a torsion spring is movably sleeved on the surface of the rotating shaft. The two ends of the torsion spring are respectively fixedly connected to the surface of the rotating shaft and the inside of the slider.

[0011] As a preferred embodiment of this utility model, a take-up roller is fixedly connected to the surface of the rotating shaft, a traction rope is fixedly connected to the surface of the take-up roller, the traction rope is wound around the take-up roller, and the lower end of the traction rope is fixedly connected to the surface of the support plate.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a laboratory refrigerator for easy access to reagent kits, comprising a refrigerator body 1, a refrigerator door 2 hinged to the surface of the refrigerator body 1, the refrigerator door 2 being able to rotate up to 180 degrees, so that the presence of the refrigerator door 2 does not affect the access to and storage of reagent kits in the refrigerator body 1.

[0026] The inner wall of the refrigerator body 1 is provided with support plates 3 arranged at equal intervals, and a placement box 4 is fixedly connected to the surface of the support plate 3 for storing reagent kits. The inner wall of the placement box 4 is inclined, and a ball bearing 5 is embedded in the inner wall of the placement box 4. Thus, by means of the inclined inner wall of the placement box 4 and the ball bearing 5, after the reagent kit near the refrigerator door 2 is taken out, the reagent kit behind it can automatically slide to the outermost side under the action of the inclined inner wall of the placement box 4 and the ball bearing 5, which makes it convenient for the staff to continue to take out the reagent kits, and thus facilitates the staff to use the reagent kits.

[0027] Both sides of the inner wall of the refrigerator body 1 are fixedly connected to a lower support plate 6 and an upper support plate 10. The lower support plate 6 has an L-shaped cross section. The upper support plate 10 is located above the lower support plate 6. The two sides of the support plate 3 are located between the two sets of lower support plates 6 and upper support plates 10, respectively, to support the support plate 3. The surface of the lower support plate 6 is provided with a slide rail 11 with an L-shaped cross section. Two movable blocks 19 are fixedly connected to the surface of the support plate 3. The surfaces of the two movable blocks 19 are slidably connected to the inner walls of the two slide rails 11, respectively, to guide the movement of the support plate 3.

[0028] Both sides of the inner wall of the refrigerator body 1 are fixedly connected to slide rails 7. The inner walls of the two slide rails 7 are slidably connected to sliders 8. The bottom of the slider 8 is provided with a connecting groove 20 with a concave cross section. The surface of the support plate 3 is fixedly connected to a connecting post 9. The upper end of the connecting post 9 matches the inner wall of the connecting groove 20 to connect the slider 8 to the support plate 3.

[0029] The slider 8 is rotatably connected to a rotating shaft 13 that protrudes from the surface of the slider 8. A torsion spring 17 is movably sleeved on the surface of the rotating shaft 13. The two ends of the torsion spring 17 are fixedly connected to the surface of the rotating shaft 13 and the inside of the slider 8, respectively, to reset the rotating shaft 13.

[0030] A take-up roller 14 is fixedly connected to the surface of the rotating shaft 13, and a traction rope 12 is fixedly connected to the surface of the take-up roller 14. The traction rope 12 is wound around the take-up roller 14, and the lower end of the traction rope 12 is fixedly connected to the surface of the support plate 3 to support the top support plate 3. This prevents the top support plate 3 from being unsupported when it is pulled out, which would cause the support plate 3 to tilt and affect the use of the device.

[0031] The slider 8 has two sliding blocks 15 inside, and the cross-section of the blocks 15 is pentagonal. A spring 16 is fixedly connected between the blocks 15 and the inside of the slider 8 to reset the blocks 15. The inner wall of the slide rail 7 has a slot 18, and the blocks 15 can be inserted into the spring 16. Thus, the position of the slider 8 can be restricted by the blocks 15 and the slot 18, thereby limiting the position of the support plate 3 and preventing the top support plate 3 from moving freely in the refrigerator body 1, thus ensuring the stability of the device during use.

[0032] During operation, each set of reagent kits is placed into the placement box 4, and the reagent kits are arranged according to the order of use. When taking out a reagent kit, the outermost reagent kit is taken first. Then, under the action of the inclined inner wall of the placement box 4 and the action of the ball bearing 5, the reagent kits behind slide in the placement box 4 and become the outermost, which makes it convenient for the staff to take out the reagent kits in sequence.

[0033] When the reagent kits in the placement box 4 are used up and need to be replenished, the staff can pull the support plate 3. Through the connection of the connecting column 9 and the connecting groove 20, the support plate 3 can smoothly move, causing the slider 8 to slide synchronously along the slide rail 7. This allows the support plate 3 to be pulled out of the refrigerator body 1, simultaneously pulling the slider 8 out of the slide rail 7. At the same time, the locking block 15 on one side of the slider 8 slides out of the locking groove 18. Then, as the support plate 3 and slider 8 move, the other side of the slider 8 re-engages into the locking groove 18. At this point, the support plate 3 is completely slid out of the refrigerator body 1, and the movable block 19 enters the corner of the slide rail 11. Therefore, the support plate 3 can be pushed down at this point. This allows the movable block 19 to slide along the vertical groove of the slide rail 11, while the support plate 3 moves downwards, stretching the traction rope 12, thereby driving the take-up roller 14 and the rotating shaft 13 to rotate, which in turn drives the torsion spring 17 to twist. After the traction rope 12 is fully unwound, one end of the support plate 3 is supported by the movable block 19, and the other end is pulled and supported by the traction rope 12, so that the support plate 3 can always be in a relatively stable state after it is fully pulled out. At this time, the staff can refill the reagent kit in the placement box 4, so that the staff can replenish the reagent kit on the support plate 3 at the higher part of the refrigerator body 1 without separating the support plate 3 from the refrigerator body 1, which is convenient for the staff to use.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
