Description

Technical Field

[0001] This utility model relates to the field of storage refrigerator technology, and more specifically, to an ultra-low temperature storage refrigerator. Background Technology

[0002] Ultra-low temperature freezers are refrigeration devices that provide extremely low temperature environments. They are typically used in scientific research, medical, and industrial fields where long-term, stable preservation of temperature-sensitive biological samples, pharmaceuticals, and reagents is required. In recent years, with the widespread application of biomedical and university research technologies, the demand for ultra-low temperature cryogenic storage boxes for storing reagents and samples has been increasing.

[0003] Traditional storage refrigerators are clearly lacking in layout and user-friendliness. The layout of the refrigeration and control areas is unreasonable. Traditional storage refrigerators adopt a layout with the refrigeration area at the bottom, the storage area at the front, and the control area partially equipped. The overall height is relatively high and the space is not reasonable. Furthermore, the high position of the refrigerator storage area is inconvenient to access, requiring the use of additional tools such as ladders and stools, which is cumbersome and inconvenient, affecting the user-friendly use of the refrigerator.

[0004] Therefore, it is necessary to provide an ultra-low temperature storage refrigerator to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an ultra-low temperature storage refrigerator to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An ultra-low temperature storage refrigerator includes a cabinet, the cabinet having a door and a base, and further includes: The cooling zone and the control zone are both located on one side of the enclosure; The storage area is located on the other side of the enclosure; The pedal is slidably disposed in the base, and the bottom of the pedal is provided with a rotatable support frame; A transmission mechanism, mounted on the base, is used to drive the pedal to move horizontally and simultaneously cause the support frame to rotate.

[0007] Furthermore, a placement groove is provided at the bottom of the pedal, and a rotating shaft connected to the support frame is rotatably arranged between the two side walls of the placement groove. A first winding cylinder and a first torsion spring are provided on the rotating shaft, and the other end of the first torsion spring is connected to the side wall of the placement groove.

[0008] Furthermore, the transmission mechanism includes: A transmission cavity is formed within the base and slidably connected to the pedal; A telescopic component is disposed on the inner wall of the transmission cavity, and the telescopic end of the telescopic component is connected to the inner end of the pedal; A linkage component, located on the outer wall of the base, is used to drive the support frame to rotate during the movement of the pedal.

[0009] Furthermore, the linkage component includes: A groove is formed on the outer wall of the base. Rotating rods are rotatably provided on both sides of the groove. A second winding cylinder and a second torsion spring are provided on the rotating rods. The other end of the second torsion spring is connected to the inner wall of the groove. The elastic force of the second torsion spring is less than that of the first torsion spring. The traction rope has one end wound around the second winding drum and the other end wound around the first winding drum.

[0010] Furthermore, the control area includes a control panel, a connecting shaft rotatably mounted on the housing and connected to the control panel, and an adjustment component for driving the connecting shaft to rotate.

[0011] Furthermore, the adjustment component includes: A fixed base is provided on the outer wall of the box body, and an adjusting rod is rotatably provided on the inner wall of the fixed base. A worm gear is provided on the adjusting rod. One end of the connecting shaft extends into the fixed base and is provided with a worm wheel that meshes with the worm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this solution, the storage refrigerator breaks away from the existing layout of placing the refrigeration area at the bottom, the storage area at the front, and a control area in a partial location. Instead, it adopts a left-right layout, so that the refrigeration area and the control area are located on the left / right side of the cabinet. This provides expandable and operational space for each control module. Placing the refrigeration area on the left / right side can also make full use of space and reduce the overall height, making it convenient for transportation and placement. The storage area is located on the right / left side of the cabinet, which can improve the usable storage space, resulting in better space utilization and a more reasonable distribution.

[0013] 2. When it is necessary to retrieve or place items at higher positions in the storage area, the transmission mechanism can be operated to move the pedal inside the base outward and extend it. The support frame will gradually rotate and eventually contact the ground to support the pedal. Users can stand on the pedal to retrieve or place items at higher positions in the storage area without the need for additional ladders, stools, or other tools. This makes it more convenient for users to retrieve or place items and samples located at higher positions in the storage area, better meeting the user's humanized needs and demonstrating high practicality. After the retrieval and placement are completed, the pedal can be moved back into the base via the transmission mechanism. During the pedal's retraction, the support frame will gradually rotate to a state parallel to the pedal. Finally, the pedal and support frame move back into the base, making the operation simple and convenient. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0017] Please see Figure 1-9 An ultra-low temperature storage refrigerator includes a cabinet 1, a door 2 and a base 3 on the cabinet 1, and further includes: The refrigeration zone 4 and the control zone 5 are both located on one side inside the housing 1; Storage area 6 is located on the other side of the housing 1; The pedal 7 is slidably mounted in the base 3, and a rotatable support frame 8 is provided at the bottom of the pedal 7; The transmission mechanism 9 is mounted on the base 3 and is used to drive the pedal 7 to move horizontally and at the same time cause the support frame 8 to rotate.

[0018] The storage refrigerator of this application breaks away from the existing layout of having the refrigeration zone 4 at the bottom, the storage zone 6 at the front, and a control zone 5 partially equipped. Instead, it adopts a left-right layout, with the refrigeration zone 4, control zone 5, and storage zone 6 distributed on the left and right sides. This allows the refrigeration zone 4 and control zone 5 to be located on the left / right side of the cabinet 1, providing expandable and operational space for each control module. Placing the refrigeration zone 4 on the left / right side also makes full use of the space and reduces the overall height, facilitating transportation and placement. Meanwhile, the storage zone 6 is located on the right / left side of the cabinet 1, which increases the usable storage space, resulting in better space utilization and a more reasonable distribution.

[0019] The attached diagram shows a configuration where the cooling zone 4 and control zone 5 are on the left side, and the storage zone 6 is located on the right side of the enclosure 1.

[0020] When items need to be retrieved or placed in higher positions in storage area 6 after opening door 2, the transmission mechanism 9 can be operated via control area 5. The transmission mechanism 9 will then cause the pedal 7 inside base 3 to extend outwards. During the movement of pedal 7, support frame 8 also rotates, gradually changing from a parallel position to a perpendicular position. Finally, after pedal 7 is fully extended, support frame 8 contacts the ground, providing support and improving safety. Users can then stand on pedal 7 to retrieve or place items in higher positions in storage area 6 without the need for ladders, stools, or other tools. This makes it more convenient for users to access items and samples located in higher positions in storage area 6, better meeting user needs and demonstrating high practicality.

[0021] After the retrieval and placement are completed, the pedal 7 can be moved back into the base 3 by the transmission mechanism 9. During the retraction of the pedal 7, the support frame 8 will also gradually rotate to the bottom of the pedal 7. That is, the support frame 8 will gradually rotate from a state perpendicular to the pedal 7 to a state parallel to the pedal 7. Finally, the pedal 7 and the support frame 8 will move back into the base 3. The operation is simple and convenient.

[0022] In addition, the control area 5 can work in conjunction with the door 2. For example, when the door 2 is opened to 90 degrees, the transmission mechanism 9 will start and drive the pedal 7 to extend. When the door 2 is closed to less than 90 degrees, the transmission mechanism 9 will start in the opposite direction and drive the pedal 7 to retract, further reducing the user's operation process.

[0023] For preferred options, please refer to [link / reference]. Figure 3-5 and Figure 8 The bottom of the pedal 7 is provided with a placement groove 10. A rotating shaft 11 connected to the support frame 8 is rotatably arranged between the two side walls of the placement groove 10. A first winding cylinder 12 and a first torsion spring 13 are provided on the rotating shaft 11. The other end of the first torsion spring 13 is connected to the side wall of the placement groove 10.

[0024] Specifically, when the pedal 7 is inside the base 3, the support frame 8 is in the placement slot 10, such as... Figure 8 When the pedal 7 inside the base 3 is moved outward and extended by the transmission mechanism 9, the transmission mechanism 9 will simultaneously drive the rotating shaft 11 to rotate. At this time, the rotating shaft 11 will drive the support frame 8 to rotate, and the first torsion spring 13 will gradually undergo elastic deformation, causing the support frame 8 to rotate out of the placement slot 10 and finally be in a vertical state, as shown. Figure 3 and Figure 5 state.

[0025] When the pedal 7 is retracted via the transmission mechanism 9, the transmission mechanism 9 no longer drives the rotating shaft 11 to rotate. At this time, the rebound force of the first torsion spring 13 will drive the rotating shaft 11 to reverse and reset. That is, the rotating shaft 11 will drive the support frame 8 to gradually rotate to a horizontal state. Finally, the support frame 8 rotates into the placement slot 10 and then returns to the base 3 along with the pedal 7.

[0026] In this embodiment, preferably as described in 5-8, the transmission mechanism 9 includes: The transmission cavity 91 is located inside the base 3 and is slidably connected to the pedal 7; Telescopic component 92 is disposed on the inner wall of transmission cavity 91, and the telescopic end of telescopic component 92 is connected to the inner end of pedal 7; Linkage component 93 is located on the outer wall of base 3 and is used to drive support frame 8 to rotate during the movement of pedal 7.

[0027] Specifically, the telescopic component 92 in this application can be an electric telescopic rod. The telescopic component 92 can drive the pedal 7 to extend or retract, that is, to extend the pedal 7 out of the transmission cavity 91 or move it back into the transmission cavity 91. During the movement of the pedal 7, the linkage component 93 will drive the support frame 8 to rotate. That is, after the pedal 7 extends, the support frame 8 rotates to a vertical position to support the pedal 7; when the pedal 7 retracts, the support frame 8 rotates to a horizontal position and returns to the placement slot 10.

[0028] In this embodiment, preferably, please refer to [reference needed]. Figure 3-6 and Figure 8 The linkage component 93 includes: A groove 931 is formed on the outer wall of the base 3. Rotating rods 932 are rotatably arranged on both sides of the groove 931. A second winding cylinder 933 and a second torsion spring 934 are provided on the rotating rods 932. The other end of the second torsion spring 934 is connected to the inner wall of the groove 931. The elastic force of the second torsion spring 934 is less than that of the first torsion spring 13. The traction rope 935 has one end wound around the second winding drum 933 and the other end wound around the first winding drum 12.

[0029] Specifically, the process of the telescopic component 92 driving the pedal 7 to extend outward is divided into: First stage: The first winding cylinder 12 moves outward with the rotating shaft 11. Since the elastic force of the first torsion spring 13 is greater than that of the second torsion spring 934, the rotating shaft 11 and the support frame 8 do not rotate, that is, the support frame 8 does not rotate. However, the traction rope 935 will pull the second winding cylinder 933 and the rotating rod 932 to rotate, so that the traction rope 935 wound on the second winding cylinder 933 is released, and the second torsion spring 934 also undergoes elastic deformation. Second stage: When the traction rope 935 wound on the second winding drum 933 is fully released, the support frame 8 is completely outside the base 3, and the pedal 7 continues to move outward. At this time, the traction rope 935 will pull the first winding drum 12 to rotate with the rotating shaft 11. That is, the traction rope 935 wound on the first winding drum 12 is gradually released, and the first torsion spring 13 undergoes elastic deformation. At this time, the support frame 8 will rotate downward with the rotating shaft 11. Finally, when the pedal 7 moves outward into place, the support frame 8 is vertical and in contact with the ground, thus achieving the supporting effect on the pedal 7.

[0030] Similarly, the process of telescopic component 92 retracting pedal 7 into base 3 is divided into: First stage: When the pedal 7 moves back, the rebound force of the first torsion spring 13 will drive the first winding cylinder 12 and the rotating shaft 11 to rotate and reset. The first winding cylinder 12 gradually winds the traction rope 935, that is, the rotating shaft 11 causes the support frame 8 to gradually rotate into the placement slot 10. When the support frame 8 is outside the base 3, it has already returned to the placement slot 10. Second stage: The pedal 7 continues to move back. At this time, the rebound force of the second torsion spring 934 will drive the second winding cylinder 933 and the rotating rod 932 to gradually rotate and reset. The second winding cylinder 933 will gradually wind the traction rope 935. Finally, when the pedal 7 and the support frame 8 return to the transmission cavity 91 of the base 3, the second torsion spring 934 and the second winding cylinder 933 complete the reset.

[0031] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 9The control area 5 includes a control panel 14. A connecting shaft 15 connected to the control panel 14 is rotatably mounted on the housing 1. An adjustment component 16 for driving the connecting shaft 15 to rotate is also provided on the housing 1.

[0032] Specifically, the connecting shaft 15 can be rotated by adjusting component 16, which in turn drives the control panel 14 to rotate, thereby allowing the control panel 14 to rotate to an angle suitable for the user. This allows for adaptive adjustments based on different users to achieve a more comfortable operating effect. Adjusting the tilt angle of the control panel 14 can also better match the comfortable area of ​​the human eye, further improving the humanization of this storage refrigerator.

[0033] The adjustment component 16 can be located inside or outside the housing 1, depending on the needs.

[0034] In this embodiment, preferably, please refer to [reference needed]. Figure 4 and Figure 6 The adjustment component 16 includes: A fixed base 161 is provided on the outer wall of the housing 1. An adjusting rod 162 is rotatably provided on the inner wall of the fixed base 161, and a worm gear 163 is provided on the adjusting rod 162. One end of the connecting shaft 15 extends into the fixed seat 161 and is provided with a worm wheel 164 that meshes with the worm 163.

[0035] Specifically, this application provides one method for adjusting component 16: Rotating the adjusting rod 162 will drive the worm gear 163 to rotate, which in turn will drive the worm wheel 164 and the connecting shaft 15 to rotate. The connecting shaft 15 will then drive the control panel 14 to rotate, allowing the angle of the control panel 14 to be adjusted as needed. The operation is simple and convenient.

[0036] Furthermore, the worm gear 164 and worm 163 are self-locking, meaning that the worm gear 164 and connecting shaft 15 can only be driven to rotate by rotating the adjusting rod 162 and worm 163, and vice versa. This prevents the control panel 14 from rotating when it is being operated, thus improving operational stability.
