[0034] Example 1

[0035] like Figure 1-6 As shown, the present invention proposes a low-temperature preservation device for collagen solution, which includes a refrigeration cabinet 1, a partition 6, a rotating frame, and a support assembly.

[0036] The rotating rack has multiple supports and is rotatably installed inside the refrigeration cabinet 1. The side of the rotating rack is provided with a sealed door that covers the front of the refrigeration cabinet 1 and allows items to be placed or removed from each layer of the multi-layer rotating rack during use.

[0037] The number of support components is multiple, and the multiple support components are slidably mounted on the rotating frame and arranged at equal angles according to the center of the rotating frame. At the end of the support component and inside the refrigeration cabinet 1, there is a limiting component for limiting the position of the support component in use.

[0038] There are multiple partitions 6, and multiple partitions 6 are arranged on the upper surface of each layer of the rotating frame and located on both sides of the support assembly. They are used to limit the solution on the support assembly during use and reduce the possibility of solution falling off during the rotation of the rotating frame.

[0039] In this embodiment, the rotating frame is rotated and adjusted according to the placement angle of the support components, so that some of the support components placed along the height direction of the rotating frame are placed towards the sealing door. Each layer of the multi-layer rotating frame is opened and closed separately through the sealing door, so that each layer of the rotating frame is opened and closed independently, avoiding leakage of solution from other layers and improving the storage effect. At the same time, the support components are moved through the sealing door on the rotating frame to the front of the refrigeration cabinet 1, and the solution is placed and removed on the support components. The support components are then reset, and the refrigeration cabinet 1 is sealed, making it more convenient to place and remove the solution.

[0040] Example 2

[0041] like Figure 2-3 As shown, the present invention proposes a low-temperature preservation device for collagen solution. Compared with the first embodiment, the difference in this embodiment is that the rotating frame includes a support plate 10, a rotating rod 11, a transmission component 12, and a motor 13.

[0042] The rotating rod 11 is rotatably installed inside the refrigeration cabinet 1 and its bottom end extends to the inside of the bottom end of the refrigeration cabinet 1;

[0043] There are multiple support plates 10, which are installed at equal intervals on the refrigeration cabinet 1 and located inside the refrigeration cabinet 1. Multiple connecting grooves 17 are provided at equal angles on the edges of the support plates 10.

[0044] The motor 13 is located on the inner side of the bottom end of the refrigeration cabinet 1 and is connected to the rotating rod 11 through the transmission component 12. The transmission component 12 is one of the chain drive, gear drive and belt drive structures.

[0045] In this embodiment, the transmission component 12 causes the motor 13 to drive the rotating rod 11 to rotate in the refrigeration cabinet 1, thereby causing the support plate 10 to rotate synchronously, and the support plate 10 to drive the support assembly to adjust its position, making the adjustment of the support assembly more convenient, and making the loading and unloading of the solution more convenient.

[0046] Example 3

[0047] like Figure 1-4As shown, the present invention proposes a low-temperature preservation device for collagen solution. The difference between this embodiment and the first embodiment is that the sealing door includes a main door body 2, a secondary door body 3, and a quick-opening latch 4.

[0048] The main door 2 is hinged to the front of the refrigeration cabinet 1 and covers the refrigeration cabinet 1;

[0049] The secondary door 3 is hinged to the middle of the main door 2, and the secondary door 3 is arranged in a one-to-one correspondence with the support plate 10;

[0050] The quick-opening latch 4 is installed on the main door body 2 and connected to the secondary door body 3.

[0051] In this embodiment, when the main door 2 closes and seals the refrigeration cabinet 1, the quick-opening latch 4 opens and closes the secondary door 3 on the side of the support plate 10 to the middle of the main door 2. The secondary door 3 is arranged one-to-one with the support plate 10, so that the side of each support plate 10 can be opened and closed independently. At the same time, the support assembly moves to the outside of the refrigeration cabinet 1 through the secondary door 3, making it more convenient to place the solution onto the support assembly and avoiding leakage of solution on other support plates 10, thus improving the storage effect.

[0052] Example 4

[0053] like Figure 5-6 As shown, the present invention proposes a low-temperature preservation device for collagen solution. The difference between this embodiment and the first embodiment is that the support assembly includes a support plate 7 and a slide bar 14.

[0054] Support plate 7 is disposed inside the connecting groove 17;

[0055] There are two slide bars 14, which are installed on the middle of the side of the support plate 7 and are slidably connected to the support plate 10.

[0056] In an optional embodiment, both inner walls of the connecting groove 17 are provided with sliding grooves 16. When the slide bar 14 and the support plate 10 are installed together, the slide bar 14 is accommodated in the sliding groove 16, which is used to limit the movement of the support plate 7 and support the support plate 7 during use.

[0057] In an optional embodiment, a notch 19 is provided below one end of the slide 16 and near the middle of the support plate 10. Connecting posts 15 are provided on both sides of one end of the support plate 7. The size of the connecting posts 15 is arranged to match the notch 19. Furthermore, a limiting groove 18 communicating with the notch 19 is provided on the inner side of the slide 16. The length of the connecting post 15 is greater than the depth of the slide 16. The end of the connecting post 15 is accommodated in the limiting groove 18. During use, the connecting post 15 supports the end of the support plate 7 in the limiting groove 18, and the end of the limiting groove 18 limits the support plate 7 to prevent it from moving outward of the refrigeration cabinet 1 and falling off.

[0058] In this embodiment, by tilting the support plate 7 and moving the connecting column 15 from the notch 19 to the limiting groove 18 below the support plate 10, and moving the connecting column 15 to the end of the limiting groove 18 and the edge of the support plate 10, the support plate 7 is placed horizontally and reset, so that the support plate 7 drives the slide bar 14 to slide in the slide groove 16. The cooperation between the slide bar 14 and the slide groove 16 supports and limits the movement of the support plate 7. The support plate 7 drives the slide bar 14 to slide outward in the slide groove 16, so that the support plate 7 is placed outside the refrigeration cabinet 1 for the operation of loading and unloading solutions. At the same time, the connecting column 15 is connected to the inner wall of the end of the limiting groove 18 to limit the support plate 7 and prevent the support plate 7 from falling off due to excessive movement distance.

[0059] Example 5

[0060] like Figure 2-3 As shown, the present invention proposes a low-temperature preservation device for collagen solution. The difference between this embodiment and the first embodiment is that the limiting component includes a limiting plate 5, a limiting ring 8, and a support rod 9.

[0061] There are multiple limiting rings 8, and all the limiting rings 8 are sleeved on the outside of the support plate 10 and connected to the end of the support plate 7. The side of the limiting ring 8 is provided with an opening on the side of the sub-door body 3.

[0062] The limiting plate 5 is set at the opening of the limiting ring 8, and one end is attached to the support plate 7, while the other end is fixedly connected to the sub-door body 3.

[0063] The support rod 9 is installed on the inside of the refrigeration cabinet 1 and connected to multiple limit rings 8.

[0064] In this embodiment, multiple limiting rings 8 are respectively sleeved on the outside of the support plate 10 by the cooperation of multiple support rods 9, and the limiting plate 5 is installed on the side of the sub-door body 3. The cooperation of the limiting plate 5 and the limiting rings 8 limits the position of the support plate 7 and the solution, preventing the support plate 7 from sliding during the rotation of the support plate 10, and avoiding the solution from falling off.

[0065] In this invention, the main door 2 closes the refrigeration cabinet 1, and the transmission component 12 drives the motor 13 to rotate the rotating rod 11 within the refrigeration cabinet 1, thereby causing the support plate 10 to rotate synchronously. The support plate 10 then moves the supporting plate 7 to the side of the secondary door 3. The secondary door 3 is arranged in a one-to-one correspondence with the support plate 10, allowing the middle of the main door 2 to open and close with the support plate 10. This enables multiple support plates 10 to open and close independently. Simultaneously, the supporting plate 7 slides outwards from the refrigeration cabinet 1 via the slide bar 14, and the connecting column 15 limits the position of the supporting plate 7. This allows one end of the support plate 7 to be placed on the outside of the refrigeration cabinet 1, and the solution to be placed or removed on the support plate 7. At the same time, the support plate 7 is reset, and the quick-opening latch 4 closes the secondary door 3 onto the main door 2, thus resealing the refrigeration cabinet 1. Simultaneously, through the cooperation of multiple support rods 9, multiple limiting rings 8 are respectively fitted onto the outside of the support plate 10, and the limiting plate 5 is installed on the side of the secondary door 3. The cooperation of the limiting plate 5 and the limiting rings 8 limits the position of the support plate 7 and the solution, preventing the support plate 7 from sliding during the rotation of the support plate 10 and avoiding the solution from falling off.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
