Technical Field

[0001] This utility model relates to the field of storage box technology, specifically a low-temperature frozen storage box that can realize multi-layer storage. Background Technology

[0002] Low-temperature cryogenic storage boxes utilize refrigeration systems to create a low-temperature preservation environment. In laboratories, low-temperature cryogenic storage boxes are often needed when storing samples. Small low-temperature cryogenic storage boxes are convenient for transferring and temporarily storing items. However, traditional low-temperature freezer storage boxes are difficult to store and support corresponding items in layers, which can easily lead to wasted space. Moreover, it is inconvenient to take out and put in items on the corresponding layers during storage, making them relatively inconvenient to use. Utility Model Content

A freezing cavity is provided on the front of the storage box body, and a hinged door is provided on the front of the storage box body. One end of the hinged door is hinged to the storage box body, and a handle is provided on the other end of the front of the hinged door. Several sets of load-bearing components are provided inside the freezing cavity. Each load-bearing component includes a sliding frame, a load-bearing plate, and a connector. Sliding frames are symmetrically arranged on the left and right sides inside the freezing cavity. The load-bearing plate is slidably connected to the sliding frames and protrudes beyond the sliding frames. The connecting component includes a crossbeam, a worm gear, a worm, a handle, a screw, and a positioning block. The front of the bearing plate is connected to the crossbeam. A movable groove is provided in the middle part of the crossbeam, and a worm gear and a worm are provided in the movable groove. The worm gear and the worm mesh. The worm passes through the crossbeam and is connected to the handle. A storage groove is symmetrically provided on the left and right sides of the crossbeam, and a positioning block is provided in the storage groove. A screw extending into the storage groove is symmetrically provided on the left and right sides of the center of the worm gear. One end of the positioning block is threadedly connected to one end of the screw. The left and right sides of the freezing chamber are also provided with slots that are adapted to the other end of the positioning block.

[0005] Preferably, the other end of the positioning block is rounded.

[0006] To facilitate stable driving of the handle, this utility model is improved by providing several sets of friction textures on the handle.

[0007] To facilitate understanding the position of the handle rotation, this utility model is improved by providing an indicator block on the front edge of the handle.

[0008] To facilitate stable support for the storage box body, the present invention is improved by providing threaded grooves at the four corners of the lower part of the storage box body, and a support member is also provided at the lower part of the storage box body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 A low-temperature cryogenic storage box capable of multi-layer storage includes a storage box body 1, a hinged door 2, a handle 3, and a load-bearing assembly. The storage box body 1 has a freezing cavity on its front side. The hinged door 2 is hinged to the storage box body 1 at one end, and a handle 3 is located at the other end of the front side of the hinged door 2. Several sets of load-bearing assemblies are arranged inside the freezing cavity. Each load-bearing assembly includes a sliding frame 4, a support plate 5, and a connector. Sliding frames 4 are symmetrically arranged on the left and right sides of the freezing cavity. The support plate 5 is slidably connected to the sliding frame 4 and protrudes from the sliding frame 4, connecting to the connector. The connector includes a crossbeam 6. The system includes a worm gear 7, a worm 8, a handle 9, a screw 10, and a positioning block 11. The front of the bearing plate 5 is connected to the crossbeam 6. The crossbeam 6 has a movable groove in its middle section, in which the worm gear 7 and the worm 8 are installed. The worm gear 7 and the worm 8 mesh with each other. The worm 8 passes through the crossbeam 6 and is connected to the handle 9. The crossbeam 6 has symmetrical storage grooves on its left and right sides, in which the positioning block 11 is installed. The worm gear 7 has screws 10 extending into the storage grooves on its left and right sides. One end of the positioning block 11 is threaded to one end of the screw 10. The freezing chamber also has slots on its left and right sides that are adapted to the other end of the positioning block 11.

[0016] In this embodiment, screw grooves are provided at the four lower corners of the storage box body 1. A support member is also provided below the storage box body 1. The support member includes a support foot 15 and a stud 16. A stud 16 that is threadedly connected to the screw groove is provided above the support foot 15. A friction pad 17 is also provided below the support foot 15.

[0017] Move the storage box body 1 to a well-ventilated, heat-free area in the laboratory and achieve horizontal alignment through the support components: the studs 16 above the support feet 15 are threadedly connected to the screw grooves at the four corners of the storage box body 1. Rotate the support feet 15 (with the friction pads 17 facing down) to provide stable support for the storage box body 1. The storage box body 1 is a freezer that can be refrigerated.

[0018] The sliding frames 4 on the left and right sides of the freezing chamber (made of low-temperature resistant ABS material, no brittleness at -86℃): When storing small volume samples (such as 2ml cryovials, 5cm high), 5 sets of support components are installed, with a layer spacing of 5cm; when storing large volume samples (such as 500ml reagent bottles, 15cm high), the upper and lower sets of support plates 5 connected to the connectors in the middle support component can be removed. Initially, the positioning block 11 is retracted into the storage groove, and the bearing plate 5 is slidably connected to the sliding frame 4 (fitting gap ≤ 0.5mm). During installation, the two ends of the bearing plate 5 are aligned with the groove of the sliding frame 4 and pushed in parallel. When the crossbeam 6 contacts the sliding frame 4, the positioning block 11 is aligned with the slot. The handle 9 with friction texture 13 (friction texture 13 tooth depth 0.5mm, grip friction force ≥ 0.8, to prevent low temperature slippage) is rotated, driving the worm 8 in the movable groove of the crossbeam 6 to rotate (speed 50-100rpm). Through meshing with the worm wheel 7 (transmission ratio 1:1), the screws 10 on both sides of the worm wheel 7 (left-hand left-hand, right-hand right-hand) extend synchronously, so that the positioning block 11 is inserted into the slot on the side wall of the freezing cavity (the end of the positioning block 11 is rounded 12, the insertion resistance ≤ 3N, to prevent jamming). The positioning status is determined by the indicator block 14 on the edge of the handle 9. When the indicator block 14 points to the mark corresponding to "lock", the positioning block 11 is fully inserted and the bearing plate 5 is fixed (pull-out force ≥10N, shaking amount ≤0.5mm); when it points to the mark corresponding to "open", the positioning block 11 retracts into the storage groove and the bearing plate 5 can be pulled out to avoid operational errors. In this embodiment, the support plate 5 is also provided with several sets of support holes. Depending on the sample vessel to be supported, a support plate 5 with corresponding support holes needs to be selected.
