Abstract
Description
Technical Field
[0001] This utility model relates to the field of constant temperature storage technology, and more specifically, to a constant temperature storage device for a standard substance of organic solution in methanol. Background Technology
[0002] Methanol is an organic compound and the simplest saturated monohydric alcohol. It is a colorless and transparent liquid with a pungent odor and is highly volatile. The organic solvent standard in methanol is sensitive to temperature and must be kept in a constant low-temperature environment to prevent the components from decomposing or deteriorating.
[0003] The existing storage boxes are static, which causes cells and nutrients to settle, limiting the absorption of nutrients by cells, thus reducing cell metabolism, affecting cell biological activity, and hindering cell storage.
[0004] A search revealed that Chinese patent CN220936481U discloses a cell constant temperature storage device. The device can mount a culture dish on a tray, and when a servo motor is activated, the pusher plate shakes, causing the liquid inside the culture dish to vibrate. This provides uniform vibration stimulation to the culture, increases the probability of cell contact with nutrients, promotes metabolism and material exchange within the organism, and ensures the survival rate of stored cells.
[0005] In actual use, the air in the aforementioned cell thermostatic storage device will naturally convect inside the storage box, with hot air rising and cold air sinking, resulting in significant temperature differences in different locations inside. These temperature differences will affect the storage quality and noise of the methanol solution. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a constant temperature storage device for organic solution standard substances in methanol, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A constant temperature storage device for a standard organic solution in methanol includes a constant temperature chamber body, a cabinet door installed on the front side of the constant temperature chamber body, a protective box fixedly connected inside the constant temperature chamber body, a circulation component installed inside the protective box, two storage boxes arranged inside the constant temperature chamber body, and multiple limiting mechanisms installed inside the storage boxes.
[0009] The circulation component includes a stepper motor, which is fixedly connected to the inside of the protective box. A gear is fixedly connected to the output end of the stepper motor, and two racks mesh with the outer side of the gear. A connecting plate is fixedly connected to one side of the racks, and a movable box is fixedly connected to one end of the connecting plate. A first guide rod is fixedly connected to the inside of the movable box, and the first guide rod is fixedly connected to the inside of the constant temperature chamber body. A motor is installed inside the movable box, and a vortex fan is fixedly connected to the output end of the motor. Multiple first guide grooves are opened on the inside of the constant temperature chamber body, and two flow guide plates are fixedly connected inside the constant temperature chamber body. Multiple second guide grooves are opened on one side of the flow guide plates, and multiple second guide rods are fixedly connected inside the constant temperature chamber body. A connecting frame is slidably connected to the outer side of the second guide rods.
[0010] By adopting the above technical solution, the laminar flow state of unidirectional airflow can be broken, turbulence can be generated, and the mixing of hot and cold air can be accelerated.
[0011] As a further description of the above technical solution: the limiting mechanism includes a limiting ring, which is fixedly connected to the inside of the connecting plate. Multiple telescopic springs are fixedly connected to the inner side of the limiting ring. One end of each telescopic spring is fixedly connected to a limiting plate. An anti-slip strip is fixedly connected to the front side of the limiting plate. A sliding rod is fixedly connected to the other side of the limiting plate. A guide cylinder is slidably connected to the outer side of the sliding rod. One end of the guide cylinder is fixedly connected to the inner side of the limiting ring.
[0012] By adopting the above technical solution, a radially uniform clamping force can be provided on the outside of the storage bottle, thereby maintaining the stability of the storage bottle during storage.
[0013] The technical effects and advantages of this utility model are as follows:
[0014] 1. By setting up a circulation component, compared with the existing technology, two vortex fans move back and forth to generate convection at the same time. The air flow circulation is achieved by guiding multiple second guide channels and first guide channels. This can break the laminar flow state of unidirectional airflow, generate turbulence, and accelerate the mixing of hot and cold air. This can reduce the temperature gradient inside the constant temperature chamber caused by uneven heat source distribution or local heat dissipation differences, and improve the temperature uniformity.
[0015] 2. By setting a limiting mechanism, compared with the existing technology, multiple ring-shaped limiting plates are used to clamp and limit the outside of the storage bottle, which can provide a radially uniform clamping force on the outside of the storage bottle and fit closely to the outside of the storage bottle, reducing the leakage of solution or breakage of the bottle due to shaking and collision, thereby maintaining the stability of the storage bottle.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6 The device shown is a constant temperature storage device for a standard substance of organic solution in methanol, including a constant temperature chamber body 1, a cabinet door 23 installed on the front side of the constant temperature chamber body 1, a protective box 2 fixedly connected inside the constant temperature chamber body 1, a circulation component installed inside the protective box 2, and two storage boxes 16 arranged inside the constant temperature chamber body 1, with multiple limiting mechanisms installed inside the storage boxes 16.

Two racks 5 mesh with the outer side of the gear 4. A connecting plate 6 is fixedly connected to one side of the racks 5. A movable box 7 is fixedly connected to one end of the connecting plate 6. A first guide rod 8 is fixedly connected to the inside of the movable box 7. The first guide rod 8 is fixedly connected to the inside of the constant temperature chamber body 1. A motor 9 is installed inside the movable box 7. A vortex fan 10 is fixedly connected to the output end of the motor 9. Multiple first guide grooves 11 are opened inside the constant temperature chamber body 1. Two flow guide plates 12 are fixedly connected inside the constant temperature chamber body 1. Multiple second flow guides are opened on one side of each flow guide plate 12. The constant temperature chamber body 1 has multiple second guide rods 14 fixedly connected inside the groove 13. The outer side of the second guide rods 14 is slidably connected to the connecting frame 15. The reciprocating rotation of the gear 4 can mesh with two racks 5 to drive the movable box 7 to move. This allows the movable box 7 to drive the two vortex fans 10 to move back and forth. The inclined design of the two vortex fans 10 can generate convection and turbulence when the two vortex fans 10 are staggered, which can accelerate the mixing of hot and cold air. The air circulation can be achieved by the guidance of multiple first guide grooves 11 and second guide grooves 13, so as to reduce the temperature gradient inside the constant temperature chamber body 1 caused by uneven heat source distribution or local heat dissipation differences.
[0026] Reference Figure 3 and 6 As shown, the limiting mechanism includes a limiting ring 17, which is fixedly connected to the inside of the connecting plate 6. Multiple telescopic springs 18 are fixedly connected to the inside of the limiting ring 17. One end of each telescopic spring 18 is fixedly connected to a limiting plate 19.

By utilizing the telescopic action of the multiple telescopic springs 18, the multiple limiting plates 19 can be clamped on the outside of the storage bottle. At the same time, the multiple limiting plates 19 can fit against the outside of the storage bottle, reducing the leakage of solution or breakage of the bottle due to shaking and collision, thereby maintaining the stability of the storage bottle.
[0027] Working principle of this utility model: This utility model designs a constant temperature storage device for standard substances of organic solutions in methanol, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when methanol solution needs to be stored, the storage bottle is first inserted into the groove inside the storage box 16. The cross-sections of multiple limiting plates 19 facilitate the easy insertion of the storage bottle into the storage box 16. Through the compression of the storage bottle, and the sliding connection between the slide rod 21 and the inner side of the guide cylinder 22, the limiting plates 19 can compress the telescopic spring 18 inside the limiting ring 17. The spring force of the multiple telescopic springs 18 allows the multiple ring-distributed limiting plates 19 to clamp the storage bottle. Then, the constant temperature chamber body 1 is started, which can achieve constant temperature. At the same time, the stepper motor 3 is started, which drives the gear 4 to rotate, so that the gear 4 meshes and drives the two racks. 5 moves in opposite directions so that rack 5 can drive movable box 7 to move through connecting plate 6. Movable box 7 is slidably connected to the inner side of first guide rod 8 so that movable box 7 can drive vortex fan 10 to move back and forth. At the same time, two motors 9 are started to drive vortex fan 10 to rotate. By tilting the two vortex fans 10 relative to each other, the two vortex fans 10 can generate convection. By using the reciprocating movement of movable box 7, vortex fan 10 can drive the air flow inside constant temperature chamber 1. The air convection is upward and can be guided by the sloping cut surface of two guide plates 12 and multiple second guide grooves 13. The air flows downward through multiple first guide grooves 11 into the protective box 2, thereby realizing air circulation.
