The working principle of the invention is as follows:
the initial state is that the top of the sealing door plate 52 is located at one side of the vertical edge in the L-shaped groove 51, the test tube rack 2 is located at one side of the linear groove 53 far away from the sealing door plate 52, the limiting column 54 is located at one side of the rotation limiting rod 55 far away from the top of the cell transfer box 1, the reset spring 56 is not stretched, and the vertical spring group 61 and the transverse spring 67 are not compressed.
The following steps are specifically executed:
The cells are put into the test tube rack 2, as shown in fig. 1 to 6, the operator manually removes the positioning pins on the surface of the sealing door plate 52 and presses the bottom surface of the sealing door plate 52, and at this time, the sealing door plate 52 is wholly pressed by the operator, so that the movement trend towards the water pump 4 is generated, but the sealing door plate 52 is limited by the L-shaped groove 51, so that the bottom of the sealing door plate 52 slides towards the water pump 4 towards the side of the horizontal edge of the L-shaped groove 51 in compliance with the pressing force applied by the operator, and at the same time, the top of the sealing door plate 52 also slides towards the bottom of the cell transfer box 1 at the side of the vertical edge of the L-shaped groove 51.
As shown in fig. 7, when the bottom of the sealing door plate 52 enters the cell transfer box 1, the bottom of the sealing door plate 52 will collide with the bottom of the rotation limiting rod 55, and the rotation limiting rod 55 rotates with the center as a rotation pivot, so that the rotation limiting rod 55 makes the test tube rack 2 generate the same rotation trend through the limiting post 54, but the test tube rack 2 and the limiting post 54 cannot rotate under the limitation of the linear slot 53, so that under the guiding effect of the linear slot 53, the test tube rack 2 converts the rotation trend into the sliding motion towards the water pump 4, further at this time, the test tube rack 2 slides in the linear slot 53 towards the side away from the water pump 4, after the limiting post 54 slides to the top of the rotation limiting rod 55, the whole test tube rack 2 slides out of the cell transfer box 1, in the process, the reset spring 56 is pulled by the test tube rack 2 and is in a stretching state, and at this moment, the test tube rack 2 is integrally exposed outside, at this moment, the operator clamps the sealing door plate 52 on the surface of the cell transfer box 1 again through the locating pin, and put the test tube containing cells into the test tube rack 2, in the process of opening through the sealing door plate 52, can drive the test tube rack 2 to integrally slide out of the device, and further realize multiple improvements, firstly, the convenience of operation is improved, the operator does not need to take out the test tube rack 2 one by one, the operator only needs to slide the sealing door plate 52, the test tube rack 2 can integrally slide out, and therefore, the operation steps are simplified, secondly, because the test tube rack 2 keeps stable in the sliding-out process, the risks of tilting, shaking and dropping are reduced, so that the damage to cell samples due to collision is avoided, meanwhile, the operator is not required to manually take out the test tube rack 2 integrally from the cell transfer box 1, furthermore, the collision and friction between the test tube rack 2 and the cell transfer box 1 are reduced, the risk that the cell sample is polluted is also reduced, errors and repeated labor in the operation process are reduced, an operator can more intuitively observe the state of the cell sample in the test tube rack 2 because the test tube rack 2 can integrally slide out of the device, the possibility of misoperation is reduced, and the workload and fatigue feeling of the operator are also reduced because the operation process is simpler, more convenient and faster, and the working efficiency of the operator is further improved.
As shown in fig. 1 to 7, after the test tube is assembled, the operator removes the positioning pin, at this time, the sealing door plate 52, the test tube rack 2, the limiting post 54 and the rotation limiting rod 55 are not subjected to any external force except for the gravity of the operator, and then the return spring 56 pulls the test tube rack 2 back to the initial state under the action of the elastic contraction of the return spring 56, as the above steps indicate, when the return spring 56 is stretched, the sealing door plate 52 is located inside the cell transfer box 1, and then the return spring 56 contracts at this time, the sealing door plate 52 is driven to return to the initial state again by the limiting post 54 and the rotation limiting rod 55, at this time, the operator clamps the sealing door plate 52 on the surface of the cell transfer box 1 again by the positioning pin, at this time, the cells are already loaded into the cell transfer box 1, and the cell transfer box 1 can be transported.
During transportation of automobiles or trains, the cell transfer box 1 is often subjected to vibrations of different directions and intensities due to the complexity of road conditions and other external factors.
As shown in fig. 3 to 5, when the vehicle passes over a bumpy road surface or a train passes over a rail joint, when the cell transfer box 1 is subjected to vibration from a vertical direction, the vertical spring set 61 starts to act, at this time, the vertical spring set 61 is in a continuous compression and extension process due to external vibration, and in this process, the vertical spring set 61 converts part of kinetic energy into elastic potential energy, so that direct influence of vibration on the cell transfer box 1 is reduced, meanwhile, the vertical spring set 61 drives the receiving plate 63 to synchronously move towards the supporting bottom plate 62 when contracting, and the lowering of the receiving plate 63 causes a certain rotation of the rotating bracket 64, under the limitation of the fixed rod 65, the rotating bracket 64 also pushes the sliding sleeve 66 to slide towards one side, which is close to the two sliding sleeves 66, further, in the process that the two sliding sleeves 66 slide on the fixed rod 65, the transverse spring 67 is pushed, in the compression state, at this time, the vertical spring set 61 is in the process of being continuously compressed and extended due to vibration, and in the process that the transverse spring 67 is also in the continuous compression and extension state, the process of the transverse spring 67 is in the process of directly influencing the cell transfer box 1 due to the external vibration potential energy.
As shown in fig. 3 to 5, when the vehicle turns or brakes emergently, the cell transfer box 1 receives pushing force or pulling force from the side, the transverse spring 67 is responsible for processing vibration from the horizontal direction, the transverse spring 67 synchronously transmits vibration force to the vertical spring group 61 through the sliding sleeve 66, the rotating bracket 64 and the bearing plate 63, and then the vertical spring group 61 and the transverse spring 67 synchronously disperse the impact force through own elasticity at this time, so as to reduce the vibration of the cell transfer box 1 in the horizontal direction, and the vertical and horizontal vibration can cause the vertical and horizontal vibration of the vertical spring group 61 and the transverse spring 67 to absorb the vibration reasonably, so that the cell transfer box 1 is better protected, the vibration of the cell transfer box 1 is reduced, the ingenious matching of the transverse spring 67 and the vertical spring group 61 is realized, the cell transfer box 1 shows dual effects of horizontal shock absorption and vertical shock absorption on the whole structure, stability and shock resistance of the cell transfer box 1 are enhanced, safer and stable environments are provided for cells in the transportation process, impact force on the horizontal direction is firstly absorbed, displacement and shaking of the cell transfer box 1 in the horizontal direction are reduced, stability of the cell transfer box 1 is improved, meanwhile, the vertical spring group 61 is responsible for absorbing the impact force on the vertical direction, vibration of the cell transfer box 1 in the vertical direction is effectively buffered, shock resistance of the cell transfer box 1 is further enhanced, and physical damage and impact to the cells are reduced due to the stability and shock resistance of the cell transfer box 1, so that death rate of the cells is reduced.
As shown in fig. 9 and 10, during transportation, an operator needs to electrically control the external motor to start through the external controller, the output shaft of the external motor rotates to drive the rotating block 72 to synchronously rotate, and the rotating block 72 drives the vane 74 on the surface of the rotating block to synchronously rotate along the track of the circular groove 73.
In terms of ventilation, since both the air inlet 75 and the air outlet 76 are offset from the center of the ventilation housing 71, when air passes through the air outlets 76, the air does not flow straight along the center of the ventilation housing 71, but moves along an inclined path, and thus the air generates a rotational component when entering the ventilation housing 71, which helps to guide the air more smoothly through the ventilation housing 71.
Meanwhile, when the circular groove 73 rotates, the vane 74 fixed to the rotating block 72 rotates with it, and the rotating vane 74 forms a dynamic rotating passage which varies with the rotation of the vane 74, but always maintains a certain space for air to pass through, and at the same time, the inclined flow path helps to reduce the resistance of air flow, so that air can pass through the ventilation housing 71 more smoothly.
The structure utilizes Bernoulli principle in fluid mechanics, in incompressible fluid, the pressure is small at the place with high flow rate, the pressure is strong at the place with low flow rate, because the air passes through the ventilation shell 71, the flow path is inclined, and the air continuously changes along with the rotation of the vane 74, the flow rate of the air passes through the ventilation shell 71 is changed, the pressure is changed due to the change of the flow rate, so that a dynamic pressure field is formed, the pressure field helps to guide the air to pass through the ventilation shell 71 more smoothly, the ventilation effect is enhanced, and further air enters the ventilation shell 71 through the air inlet 75 and finally enters the cell transfer box 1 through the air outlet 76 for cell respiration.
In terms of dust protection, the rotation of the vane 74 within the circular groove 73 plays a vital role, the vane 74 not only forms a dynamic barrier, but also effectively prevents dust from entering the interior of the ventilation housing 71 by the centrifugal force generated by its rotation, and as the vane 74 rotates within the circular groove 73, the vane 74 constantly changes its position relative to the rotating block 72, which rotation forms a dynamic barrier, such that dust encounters the constantly changing vane 74 position when attempting to enter the ventilation housing 71, thereby increasing the difficulty of dust entry.
Second, since the mass of dust is greater than that of air, the dust is more easily affected by centrifugal force when the vane 74 rotates, and the centrifugal force is an outward force applied to the object when it rotates, which causes foreign substances such as dust to be pushed to a side away from the air inlet 75, and the effect of the centrifugal force further enhances the dust prevention effect of the ventilation dust prevention assembly.
In addition, the eccentric design of the ventilation dustproof assembly plays a key role, because the rotating block 72 deviates from the circle center of the ventilation shell 71, when the rotating block 72 drives the blades 74 to rotate, the blades 74 move along an inclined path, and the inclined moving path helps to enhance the ventilation effect, meanwhile, when air flows, dust is more easily influenced by gravity to be settled downwards, the inclined path enables the dust to be subjected to the combined action of gravity and centrifugal force when passing through the air inlet 75, the gravity pulls the dust to the bottom of the air inlet 75, the centrifugal force pushes the dust to the periphery of the air inlet 75, the dust is more difficult to enter the ventilation shell 71 under the combined action of gravity and centrifugal force, so that the dustproof effect of the ventilation dustproof assembly is enhanced under the combined action of the gravity and the centrifugal force, the inlet 75 is deviated from the circle center through the centrifugal force generated by the eccentrically arranged blades 74, the inlet 75 is effectively blocked from entering of impurities such as dust, the dust is more easily influenced by the gravity generated when the eccentrically arranged blades 74 rotate, the dust and the like are further centrifugal force can be tried to enter the air inlet 75 to be thrown away from the bottom of the air inlet 75, and the dust and the like in the air inlet 75 are prevented from entering the inside of the air inlet 71 through the air inlet 1 due to the combined action of the centrifugal force, and the centrifugal force is prevented from entering the inside of the air inlet 71.
Firstly, the structure obviously improves the sealing performance and the protective performance of the cell transfer box 1, effectively prevents the entry of pollutants such as dust, bacteria, viruses and the like, and can keep a cleaner and stable environment in the transportation process of cells, thereby reducing the risk of infection and physical damage of the cells.
Secondly, this structure improves the preservation environment of the cells, which, thanks to the effective isolation of dust and contaminants, can maintain their activity in a safer and more stable environment, which is critical for maintaining the physiological function of the cells and the success of subsequent experiments.
In addition, through avoiding the entering of impurity such as dust, also reduced death and the damage that the cell leads to because of the pollution, this has important meaning to improving the survival rate of cell transportation and guaranteeing the quality of cell sample, still helps reducing experimental failure and the repeated operation that lead to because of cell damage to improve the efficiency and the accuracy of experiment.
As shown in fig. 1 and 2, during the cell transportation process, an operator needs to add water into the water tank 3, and then the operator manually controls the external controller, and the external controller electrically controls the refrigeration element and the water pump 4 to be started.
When the outside temperature becomes high, the water in the water pipe is affected, and then the temperature of the water becomes high.
As shown in fig. 11 and 12, after the water pump 4 pumps the water in the water injection pipeline into the temperature control pipeline 81, the water with a higher temperature passes through the temperature-pack of the connecting plate 82 and contacts with the temperature-pack 83, in this process, the temperature-pack 83 is heated and expanded by a certain extent due to the higher temperature of the water, one end of the expanded temperature-pack 83 is fixedly connected with the connecting plate 82, and then most of the temperature-pack 83 continuously expands towards one side far away from the connecting plate 82, and the expansion of the temperature-pack 83 drives the valve core 84 to synchronously move towards the water tank 3, at this time, due to the movement of the valve core 84, the gap between the valve core 84 and the inner wall of the temperature control pipeline 81 gradually decreases, so that the water flow rate flowing through the valve core 84 decreases, and further, the flow rate of the water in the temperature control pipeline 81 at this time decreases synchronously.
When the flow rate of water is reduced, the contact time between water molecules and the refrigerating element arranged in the water tank 3 is prolonged, so that the heat exchange efficiency is improved, the heat in the water is absorbed and transferred to the refrigerating element, the contact time between the water and the refrigerating element is prolonged, the water is continuously refrigerated by the refrigerating element after heat exchange, and continuously enters the water channel arranged in the cell transfer box 1 through the water tank 3, the water is circulated, the water temperature in the water channel is kept at a proper temperature all the time to ensure the activity of cells, the moving distance of the valve core 84 is controlled through the thermal expansion and contraction characteristics of the temperature bulb 83, the effect of cell preservation is remarkably improved, the long-time heat exchange between the water and the refrigerating element is ensured, a stable and proper temperature environment is maintained, the survival time of cells is prolonged, the preservation effect of cells is improved, a cell sample with higher quality is provided for subsequent cell culture and experiments, the closing of the valve core 84 is controlled through the thermal expansion characteristics of the temperature bulb 83, the influence of the temperature fluctuation on the cells is reduced, the cell death rate is not improved, the medical diagnosis and the cell death rate is further improved, and the medical diagnosis of the cell sample is further provided.
