Description

Technical Field

[0001] The present invention relates to the technical field of ultra-low temperature storage boxes, and particularly to an ultra-low temperature biological storage device. Background Art

[0002] An ultra-low temperature biological storage device is a dedicated low-temperature device for long-term preservation of biological samples such as cells, tissues, DNA, viruses, vaccines, etc. Its core function is to inhibit the metabolic activities of biological samples through extremely low temperatures usually ranging from -80°C to -196°C, prevent degradation or contamination, and thus maintain the activity and stability of the samples.

[0003] A Chinese patent for an ultra-low temperature biological storage device (Publication No.: CN222187449U) is retrieved, which includes an ultra-low temperature storage, a controller, and an alarm. The ultra-low temperature storage includes an outer shell, an inner shell, a refrigerator, and a temperature sensor. The alarm is used to be installed at a position relatively far from the ultra-low temperature storage, and the alarm is signal-connected to the controller. A low-temperature range value is set in the controller. If the temperature value detected by the temperature sensor in the storage room is greater than or less than the low-temperature range value, the controller controls the alarm to give an alarm prompt. Since it includes an alarm that can be set far from the ultra-low temperature storage, the alarm can be installed in the room or area where the staff is located. When the temperature deviation occurs in the ultra-low temperature storage, the remote alarm can be used for alarm prompt. The staff can timely discover the temperature deviation in the ultra-low temperature storage and timely adjust and correct the temperature value in the ultra-low temperature storage to ensure that the biological samples in the ultra-low temperature storage will not be damaged by the temperature deviation.

[0004] This patented technology has significant advantages during use, but there are still deficiencies during use. When using a horizontal storage box, due to the large depth inside the box body, it is inconvenient to access the cylinders for large biological samples. Therefore, we propose an ultra-low temperature biological storage device to solve the existing problems. Summary of the Invention

[0005] The object of the present invention is to propose an ultra-low temperature biological storage device for the problems existing in the background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A cryogenic biological storage device, comprising a bottom plate, a storage box, a first motor, a second motor, a mounting frame, a support frame, a mounting cylinder and a clamping shaft. The rear side of the lower end of the storage box is provided with a bottom plate, a travel plate is arranged above the bottom plate, a motor is arranged at the upper end of the travel plate, a first screw rod is arranged at the upper end of the motor, a support frame is arranged at the upper end of the travel plate, a first guide rail is arranged on one inner wall of the support frame, a first nut is threadedly sleeved on the outer wall of the first screw rod, one end of the first nut is provided with a first slider slidably mounted on the outer wall of the first guide rail, one end of the first nut is provided with a mounting frame, a hook is arranged on one side below the mounting frame, and a box cover is arranged at the upper end of the storage box.

[0007] Preferably, one end of the box cover is provided with symmetrically distributed hinges, and one end of the hinge is rotatably mounted on the storage box. The box cover rotates and opens / closes at the upper end of the storage box through the hinge.

[0008] Preferably, a travel rod is arranged above the hook, a mounting cylinder is sleeved on the outer side of the travel rod, a third slider is arranged at the upper end of the mounting cylinder, and a third guide rail is arranged on one side of the lower end of the mounting frame. The third slider is slidably mounted on the outer wall of the third guide rail. The third slider and the third guide rail realize the lateral position adjustment, and manually sliding the hook can quickly adapt to the container hanging rings at different positions.

[0009] Preferably, a through hole is opened inside the mounting cylinder, the travel rod is slidably mounted inside the through hole, and a top ring is arranged at the upper end of the lower rod. The hook longitudinally slides inside the mounting cylinder through the through hole, and the top ring restricts the travel rod from disengaging, and the top ring restricts the displacement of the travel rod to prevent the sample from being damaged due to accidental detachment of the hook.

[0010] Preferably, a rotating seat is arranged at the lower end of the travel rod, and the upper end of the hook is rotatably mounted inside the rotating seat. The hook can rotate through the rotating seat, which is convenient for the hook to correspond to the hanging rings at the upper ends of biological sample storage containers at different angles during use.

[0011] Preferably, a bearing seat is rotatably mounted inside the upper end of the support frame, and one end of the first screw rod is rotatably mounted inside the bearing seat. The bearing seat rotatably supports one end of the first screw rod, improving the stability when the first screw rod rotates. The first motor drives the first screw rod to rotate, and the first nut slides on the guide rail through the first slider, driving the mounting frame to move longitudinally. The motor drive realizes the full-automatic lifting of the sample container, reducing the manual operation intensity, and the longitudinal movement structure reduces the horizontal space occupation.

[0012] Preferably, a second motor is arranged at the upper end of the bottom plate, a second screw rod is arranged at the output end of the second motor, and a bearing bracket for rotatably mounting the second screw rod is arranged at the upper end of the bottom plate. One end of the second screw rod is rotatably supported by the bearing bracket, improving the stability when the second screw rod rotates.

[0013] Preferably, guide rails II are symmetrically arranged at the upper end of the bottom plate. Symmetrically arranged sliders II are provided at the lower end of the travel plate, and the lower ends of the sliders II are slidably mounted on the outer wall of the guide rail. A nut II is provided at the lower end of the travel plate and is threadedly sleeved on the screw II. The motor II drives the screw II to rotate, and the nut II drives the mounting frame to move horizontally, so that the hook can cover multiple positions. The horizontal movement expands the coverage range of the hook, and the sample container at any position in the storage box can be accessed and stored.

[0014] Preferably, a limiting block is provided at one end of the mounting frame. Symmetrically arranged side frames are provided at one end of the box cover. Symmetrically arranged clamping shafts are embedded inside the side frames. Symmetrically arranged positioning cylinders are provided at the rear end of the box cover. One end of the clamping shaft is slidably inserted into the positioning cylinder. The limiting block prevents the slider III slidingly mounted on the guide rail III from disengaging from the guide rail III. The closed box cover is plugged by inserting the clamping shaft into the positioning cylinder.

[0015] Preferably, a handle is provided at one end of the clamping shaft. A limiting ring is sleeved on the outer wall of the clamping shaft. One end of the limiting ring is provided with a spring connected to the side frame and sleeved on the outside of the clamping shaft. The movement of the clamping shaft is convenient for adjusting the position by grasping the handle. When the position of the clamping shaft is adjusted, the spring is compressed, and the clamping shaft is elastically supported after use, preventing the clamping shaft from easily disengaging from the positioning cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the motor I drives the screw I to rotate, and the nut I drives the mounting frame to vertically lift and lower, so that the hook accurately hoists the sample container in and out of the storage box. The hook manually slides on the guide rail III through the slider III. The motor II drives the screw II to rotate, pushing the mounting frame to move horizontally to cover all storage positions in the storage box. When closing, grasping the handle drives the clamping shaft to compress the spring, and the elastic force of the spring drives the clamping shaft to insert into the positioning cylinder to achieve rigid locking, ensuring the sealing performance and preventing accidental touch, improving the convenience when accessing biological samples in the horizontal ultra-low temperature storage box.

Detailed Implementation Manner

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1-5 shown, a cryogenic biological storage device proposed by the present invention includes a bottom plate 1, a storage box 2, a first motor 3, a second motor 5, a mounting bracket 8, a support frame 10, a mounting cylinder 25, and a clamping shaft 6. The rear side of the lower end of the storage box 2 is provided with a bottom plate 1. Above the bottom plate 1 is provided a travel plate 4. At the upper end of the travel plate 4 is provided a motor, and at the upper end of the motor is provided a first screw rod 13. At the upper end of the travel plate 4 is provided a support frame 10. On one inner wall of the support frame 10 is provided a first guide rail 14. The outer wall of the first screw rod 13 is threadedly sleeved with a first nut 11. One end of the first nut 11 is provided with a first slider 12 slidably mounted on the outer wall of the first guide rail 14. One end of the first nut 11 is provided with a mounting bracket 8. One side below the mounting bracket 8 is provided with a hook 30. At the upper end of the storage box 2 is provided a box cover 7; the box door rotates and opens and closes at the upper end of the storage box 2 through a hinge 9. After the upper end of the storage box 2 is opened, biological samples enter and exit for storage through a container in a cylindrical structure. A hanging ring is provided at the upper end of the container and is sleeved by the hook 30. Inside the storage box 2 for storing biological samples, first, the hook 30 longitudinally slides inside the mounting cylinder 25 through the through hole 28. Without using a power device to drive the hook 30 to move longitudinally, the travel rod 27 moves longitudinally a small distance, and the top ring 26 is used to prevent the travel rod 27 from completely disengaging from the through hole 28. The mounting cylinder 25 slides on the outer wall of the third guide rail 23 through the third slider 24 to adjust the reciprocating position of the hook 30. When the first motor 3 operates to drive the first screw rod 13 to rotate, the first nut 11 drives the mounting bracket 8 to move longitudinally because it slides on the outer wall of the guide rail through the first slider 12, thereby longitudinally accessing and storing the container for biological samples.

[0025] One end of the box cover 7 is provided with symmetrically distributed hinges 9, and one end of the hinge 9 is rotatably installed on the storage box 2;

[0026] Above the hook 30, there is a stroke rod 27. An installation cylinder 25 is sleeved outside the stroke rod 27. At the upper end of the installation cylinder 25, there is a third slider 24. On one side of the lower end of the installation frame 8, there is a third guide rail 23. The third slider 24 is slidably installed on the outer wall of the third guide rail 23;

[0027] A through hole 28 is opened inside the installation cylinder 25. The stroke rod 27 is slidably installed inside the through hole 28. At the upper end of the lower rod, there is a top ring 26;

[0028] At the lower end of the stroke rod 27, there is a rotating seat 29. The upper end of the hook 30 is rotatably installed inside the rotating seat 29;

[0029] Inside the upper end of the support frame 10, a bearing seat 15 is rotatably installed. One end of the first screw rod 13 is rotatably installed inside the bearing seat 15;

[0030] Based on the implementation steps of Embodiment 1: The box door rotates and opens and closes at the upper end of the storage box 2 through the hinge 9. After the upper end of the storage box 2 is opened, biological samples enter and exit for storage through a container with a cylindrical structure. A hanging ring is provided at the upper end of the container and is sleeved through the hook 30. Inside the storage box 2 for storing biological samples, first, the hook 30 longitudinally slides inside the installation cylinder 25 through the through hole 28. On the premise of not using a power device to drive the hook 30 to move longitudinally, the stroke rod 27 moves longitudinally a small distance. The top ring 26 is used to prevent the stroke rod 27 from completely disengaging from the through hole 28. The installation cylinder 25 slides on the outer wall of the third guide rail 23 through the third slider 24 to adjust the reciprocating position of the hook 30. The first motor 3 operates to drive the first screw rod 13 to rotate. Since the first nut 11 slides on the outer wall of the guide rail through the first slider 12, it drives the installation frame 8 to move longitudinally, thereby longitudinally accessing and storing the container for biological samples.

[0031] As Figures 1-5As shown in the figure, compared with the first embodiment, a cryogenic biological storage device proposed by the present invention further includes: a second motor 5 is provided at the upper end of the bottom plate 1, a second screw 18 is provided at the output end of the second motor 5, and a bearing bracket 22 for rotatably installing the second screw 18 is provided at the upper end of the bottom plate 1. The second motor 5 drives the second screw 18 to rotate. Since the travel plate 4 slides on the outer wall of the second guide rail 19 through the second slider 20, when the second screw 18 rotates, it pushes the second nut to move, thereby driving the mounting bracket 8 to move horizontally. The hook 30 below the mounting bracket 8 realizes horizontal movement. The biological sample container for access and storage can move flexibly above the storage box 2 through a hoisting device, covering the entire interior of the storage box 2. After the storage box 2 is closed, grasping the handle 33 drives the clamping shaft 6 to move, drives the limiting ring 21 to move through the clamping shaft 6, and then squeezes the spring 32. During the movement of the clamping shaft 6, the spring 32 is stressed and contracts. After the box door is completely closed with the upper end of the storage box 2, the clamping shaft 6 is inserted into the positioning cylinder 17 by the elastic force of the spring 32 to lock the storage box 2 and prevent the box door from being accidentally touched and opened;

[0032] Symmetrically distributed second guide rails 19 are provided at the upper end of the bottom plate 1. Symmetrically distributed second sliders 20 are provided at the lower end of the travel plate 4, and the lower ends of the second sliders are slidably installed on the outer wall of the guide rail. A second nut threadedly sleeved with the second screw 18 is provided at the lower end of the travel plate 4;

[0033] A limiting block 16 is provided at one end of the mounting bracket 8. Symmetrically distributed side frames 31 are provided at one end of the box cover 7. A clamping shaft 6 is slidably installed inside the side frame 31. Symmetrically distributed positioning cylinders 17 are provided at the rear end of the box cover 7. One end of the clamping shaft 6 is slidably inserted into the positioning cylinder 17;

[0034] A handle 33 is provided at one end of the clamping shaft 6. A limiting ring 21 is sleeved on the outer wall of the clamping shaft 6. One end of the limiting ring 21 is provided with a spring 32 connected to the side frame 31 and sleeved on the outside of the clamping shaft 6;

[0035] In this embodiment, the second motor 5 drives the second screw 18 to rotate. Since the travel plate 4 slides on the outer wall of the second guide rail 19 through the second slider 20, when the second screw 18 rotates, it pushes the second nut to move, thereby driving the mounting bracket 8 to move horizontally. The hook 30 below the mounting bracket 8 realizes horizontal movement. The biological sample container for access and storage can move flexibly above the storage box 2 through a hoisting device, covering the entire interior of the storage box 2. After the storage box 2 is closed, grasping the handle 33 drives the clamping shaft 6 to move, drives the limiting ring 21 to move through the clamping shaft 6, and then squeezes the spring 32. During the movement of the clamping shaft 6, the spring 32 is stressed and contracts. After the box door is completely closed with the upper end of the storage box 2, the clamping shaft 6 is inserted into the positioning cylinder 17 by the elastic force of the spring 32 to lock the storage box 2 and prevent the box door from being accidentally touched and opened.
