Technical Field
[0001] This utility model relates to the field of experimental equipment technology, and more specifically, it relates to a low-temperature storage cabinet. Background Technology
[0002] Traditional low-temperature storage cabinets have large doors due to their large storage capacity. When the door is opened or closed, most of the interior space is exposed to the outside, causing a large amount of cold air to escape, resulting in poor overall performance. Therefore, this invention proposes a new type of low-temperature storage cabinet. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a low-temperature storage cabinet with the characteristics of preventing cold air escape and having a good preservation effect.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The utility model relates to a low-temperature storage cabinet, which includes a low-temperature cabinet body. The low-temperature cabinet body has a low-temperature storage chamber with an opening facing forward. The low-temperature storage chamber is provided with a door post near the opening and offset to the right. A large opening is formed on the left side of the door post and a small opening is formed on the right side. A first door panel for opening and closing the large opening and a second door panel for opening and closing the small opening are hinged to the low-temperature cabinet body. The low-temperature storage chamber is provided with at least three shelves arranged vertically at equal intervals. Each shelf is provided with a circulating tray module.
[0005] The circulating tray module includes a left sprocket and a right sprocket rotatably connected to the shelf. A chain is driven to the right sprocket and the left sprocket. Several follower brackets are arranged equidistantly along the extension trajectory on the chain. Follower trays are provided on the follower brackets. A driven gear is coaxially arranged on the right sprocket. A drive gear is meshed with the driven gear and rotatably connected to the shelf. A power assembly that controls the rotation is driven to the drive gear.
[0006] The present invention is further configured such that: a floating window assembly fixed on the body of the low-temperature cabinet is provided inside the small opening;
[0007] The floating window component includes a rectangular outer frame and an inner frame. The inner frame is slidably connected within the outer frame and can move up and down. A retractable upper curtain is connected between the upper edge of the inner frame and the upper edge of the outer frame, and a retractable lower curtain is connected between the lower edge of the inner frame and the lower edge of the outer frame.
[0008] The present invention is further configured such that the powertrain includes a geared motor.
[0009] The present invention is further configured such that: the distance between the uppermost shelf and the top of the low-temperature storage chamber is equal to the distance between two adjacent shelves; the lowermost shelf is close to the bottom of the low-temperature storage chamber.
[0010] The present invention is further configured such that the number of the layers is three.
[0011] In summary, this utility model has the following beneficial effects:
[0012] 1. The first door panel is used to open and close the large opening for loading materials before storage; the second door panel is used to open and close the small opening for unloading materials after storage. Because the second door panel is narrower, less cold air escapes during opening and closing, thus saving resources and reducing energy consumption.
[0013] 2. The shelf is equipped with a circulating tray module, which enables the storage materials to circulate within the low-temperature storage chamber and be quickly transferred to the small open position for easy retrieval.
[0014] 3. By adding a floating window component, the area connected to the outside of the small opening can be partially blocked when the stored material is taken out, thereby further preventing the escape of cold air. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0020] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0021] Example 1
[0022] See Figures 1 to 3As shown, the low-temperature storage cabinet involved in this embodiment includes a low-temperature cabinet body 1, a low-temperature storage chamber 2 with the opening facing forward, a door post 3 located near the opening and offset to the right side of the low-temperature storage chamber 2, a large opening (unmarked) is formed on the left side of the door post 3 and a small opening (unmarked) is formed on the right side, a first door panel 4 for opening and closing the large opening and a second door panel 5 for opening and closing the small opening are hinged to the low-temperature cabinet body 1, and three shelves 6 arranged vertically at equal intervals are provided in the low-temperature storage chamber 2, and a circulating tray module is provided on each shelf 6;
[0023] The circulating tray module includes a left sprocket 7 and a right sprocket 8 rotatably connected to the shelf. A chain 9 is drivenly connected to the right sprocket 8 and the left sprocket 7. Several follower brackets 10 are arranged equidistantly along the extension trajectory on the chain 9. Follower trays 11 are provided on the follower brackets 10. A driven gear 12 is coaxially arranged on the right sprocket 8. A drive gear 13 rotatably connected to the shelf is meshed on the driven gear 12. A power assembly 14 for controlling rotation is drivenly connected to the drive gear 13. The power assembly 14 includes a geared motor.
[0024] Furthermore, the distance between the topmost shelf 6 and the top of the low-temperature storage chamber 2 is equal to the distance between two adjacent shelves; the bottommost shelf 6 is close to the bottom of the low-temperature storage chamber 2.
[0025] In this embodiment, the power assembly 14 on each shelf 6 can control the drive gear 13 to rotate, which is then driven by the driven gear 12, left sprocket 7, right sprocket 8 and chain 9, causing the preserved samples placed on the corresponding follower tray 11 to circulate in the low temperature preservation chamber 2, so that the samples to be taken are close to the small opening for easy access.
[0026] Example 2
[0027] See Figures 1 to 4 As shown, the low-temperature storage cabinet involved in this embodiment is further configured, based on embodiment 1, with a floating window assembly 100 fixed on the low-temperature cabinet body 1 inside the small opening; the floating window assembly 100 includes a rectangular outer frame 15 and an inner frame 16, the inner frame 16 is slidably connected inside the outer frame 15 and can move up and down, a retractable upper curtain 17 is connected between the upper edge of the inner frame 16 and the upper edge of the outer frame 15, and a retractable lower curtain 18 is connected between the lower edge of the inner frame 16 and the lower edge of the outer frame 15.
[0028] In this embodiment, when the second door panel 5 is opened, the floating window assembly 100 still partially blocks the small opening to prevent the cold air from escaping quickly. By moving the inner frame 16 up and down, the retrieval port (i.e., the inner frame 16) can be adjusted to a suitable shelf height position to retrieve and place samples on the corresponding shelf 6.
[0029] This utility model relates to a cryogenic storage cabinet that uses a first door panel to open and close a large opening for loading materials before storage, and a second door panel to open and close a small opening for unloading materials after storage. Because the second door panel is narrower, less cold air escapes during opening and closing, thus saving resources and reducing energy consumption. By equipping the shelves with circulating tray modules, the stored materials can circulate within the cryogenic storage chamber, facilitating quick and easy transfer to the small opening for easy retrieval. Furthermore, the addition of a floating window component partially blocks the area connected to the outside through the small opening when retrieving stored materials, further preventing cold air escape. Overall, the cabinet is functionally complete and highly practical.
