Description

Technical Field

[0001] The invention belongs to the technical field of storage boxes, and in particular relates to a sample storage box with intelligent opening and closing. Background Art

[0002] Sample storage boxes are key equipment for storing biological samples. They are commonly used in laboratories and biobanks to ensure the stability and safety of samples.

[0003] When taking pathological samples, the sampled tissue embedding box needs to be fixed and stored in a storage box filled with a fixative (formalin, 40% formaldehyde) for temporary storage or transportation. Formalin (40% formaldehyde) is highly volatile and may cause respiratory mucosal irritation after inhalation. Long-term inhalation will cause formaldehyde to accumulate in the human body, which may increase the risk of cancer. Therefore, during the sampling process, the sampling doctor needs to immediately close the storage box to reduce or isolate gas volatilization before doing other work. However, if the tissue embedding boxes are stored one by one in the storage box, the storage box needs to be opened and closed frequently, which will seriously affect the work efficiency of the inspector. In view of this, a sample storage box with intelligent opening and closing is provided. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a sample storage box with intelligent opening and closing.

[0005] The technical solution adopted to solve the above technical problems is:

[0006] A sample storage box with intelligent opening and closing, comprising a box body and a top cover, wherein the top cover is movably installed at the top opening of the box body through an automatic opener and closer, the box body is filled with formalin, a lock body is installed at the joint between the box body and the top cover, and the lock body is electrically connected to the automatic opener and closer, and further comprising:

[0007] An inner frame, the inner frame is located in the middle of the box body, the inner frame divides the box body into a first accommodating chamber and a second accommodating chamber, and the first accommodating chamber and the second accommodating chamber are plugged with sample storage tubes;

[0008] Limiting bars, the limiting bars are located at two corners of the accommodating cavity, the limiting bars have cavities, and the limiting bars are vertically arranged and parallel to the axis of the sample preservation tube;

[0009] A support seat, the support seat is located at the bottom of the second accommodating cavity, and the support seat includes a hollow air cushion;

[0010] The connecting frame comprises a U-shaped main body, wherein the main body is provided with a connecting hole connecting the cavity and the air cushion. When the connecting frame moves downward, the gas in the air cushion can enter the cavity, and when the connecting frame moves upward, the outer diameter of the limit strip can be shortened.

[0011] Furthermore, both the accommodating cavity 1 and the accommodating cavity 2 are regular hexagonal cavities, the hexagonal positions of the accommodating cavity 2 are provided with limiting bars, the accommodating cavity 1 is only provided with limiting bars at the corner positions sharing the same side with the accommodating cavity 2, and the inner frame is provided with installation grooves corresponding to the limit bar positions.

[0012] Through the above technical scheme, in order to make full use of the internal space of the box body, the inner frame can divide the inside of the box body into a honeycomb shape, so that the accommodating chamber one and the accommodating chamber two can be designed with the same edge, ensuring that the accommodating chamber one and the accommodating chamber two have fully wrapped vertical side walls, while reducing the total number of side edges and simplifying the inner shell structure. In addition, the limiting bars are arranged at the hexagonal corners of the accommodating chamber two, and the sample preservation tube in the accommodating chamber two is fully wrapped and protected by the six limiting bars, which can be used to place the sample preservation tube with specimens. The accommodating chamber one also has limiting bars at the four corners to ensure the basic protection effect, and can be used to place empty sample preservation tubes. In addition, the concave and convex shapes around the inner frame caused by the hexagonal prism shape of the accommodating chamber one and the accommodating chamber two will form a buffer space between the side walls of the box body, thereby reducing the impact damage to the internal sample preservation tube caused by external impact.

[0013] Furthermore, the support seat includes a base, the base is located at the bottom of the air cushion, a flat plate is fixedly installed on the inner wall of the top end of the air cushion, and the flat plate is fixedly connected to one end of the main body located on the inner side of the air cushion.

[0014] Through the above technical scheme, when installing the air cushion, the base suspends the air cushion and leaves sufficient space for the installation and up and down movement of the main body. At the same time, the flat plate is arranged on the top surface of the air cushion. When the main body moves downward, the base can cooperate to flatten the air cushion, so that the sample preservation tube can move downward and be completely inserted into the accommodating cavity one or the accommodating cavity two. After the air cushion is flattened, the internal air will enter the cavity from the connecting hole. The limit strip is designed as an elastic thin-wall structure. After the gas enters, the outer diameter of the limit strip can be enlarged due to inflation. In addition, the limit strip is arranged in parallel with the sample preservation tube. The inflated limit strip can further squeeze the sample preservation tube for buffering, thereby improving the buffering effect.

[0015] Furthermore, the limit strip is sleeved on one end of the main body at the mounting groove, the end of the main body extends a distance above the limit strip, and the inner frame is provided with a guide hole matching the main body just above the limit strip.

[0016] Through the above technical scheme, the limit bar adopts a hollow ring shape and is coaxially sleeved and fixed on the vertical section of the main body, so that the flexible limit bar can be kept vertical. When the sample preservation tube is inserted, the limit bar that is not inflated by the air cushion can be prevented from being piled up to the lower part of the sample preservation tube due to friction, so that the limit bar can be kept as high as possible with the sample preservation tube, and the movable end of the main body is inserted into the guide hole. Even if the limit bar is inflated and squeezes the sample preservation tube, no axial deviation will occur because there is no sample preservation tube in the adjacent accommodating cavity one or accommodating cavity two to squeeze the limit bar. This ensures that a small number of sample preservation tubes can still be stably buffered and protected when the sample preservation tube is not full.

[0017] Furthermore, a top block is installed at the top of the limit bar, and a bottom block is installed at the bottom of the limit bar. The top block is fixedly connected to the main body, and the bottom block is fixedly connected to the inner frame. A through hole cooperating with the main body is opened in the middle of the bottom block.

[0018] Through the above technical scheme, the downward movement of the main body can drive the top block downward, and the limit bar is pressed downward by the cone-shaped top block which is thick at the top and thin at the bottom, so that the top of the limit bar is concave and squeezed into a reduced diameter portion one. At the same time, the bottom block is fixed to the lower part of the inner frame, and the bottom block is slidably connected to the main body. When the main body drives the limit bar downward, a middle hole which is thick at the top and narrow at the bottom is provided in the middle of the bottom block. The inner wall of the middle hole of the bottom block can squeeze the bottom of the limit bar into a reduced diameter portion two. In this way, the two ends are clamped, and the internal space of the limit bar is significantly reduced, and it can expand radially by being squeezed by the top block and the bottom block, that is, the limit bar can be deformed and squeezed between the sample preservation tube and the inner frame to form a side convex portion, thereby increasing the wrapping contact area for the sample preservation tube, and also increasing the supporting strength, thereby reducing the radial shaking of the sample preservation tube and the collision between the inner wall of the inner frame during a large horizontal impact.

[0019] Furthermore, the connecting frames are connected by a lifting frame, the top of the lifting frame extends upward over the top surface of the inner frame, an arc rod cooperating with the lifting frame is installed on the top cover near the rotation center, and an inclined hole is opened on the lifting frame corresponding to the arc rod.

[0020] The top of the lifting frame is provided with a horizontal frame structure, and all the connecting frames can be fixedly connected into a whole. The top of the lifting frame extends upward over the top surface of the inner frame, and an external force can be conveniently applied to the connecting frame through the lifting frame to drive the connecting frame up and down. In addition, an arc rod can be installed at the position of the top cover opposite to the lifting frame. When the top cover is horizontally covered on the top of the box body, the arc rod is fully inserted into the inclined hole, and the root of the arc rod will contact and press the lifting frame downward, so that the lower dead point of the connecting frame moves downward, providing driving force for flattening the air cushion and inflating the limit strip. When the top cover is swung and unfolded, the top cover drives the arc rod to move synchronously, and the arc rod can be pulled out upward from the inclined hole, and the friction force of the contact surface between the arc rod and the inclined hole drives the lifting frame and the connecting frame upward, so that the limit strip is stretched and the internal gas is reflowed into the air cushion, and the end of the connecting frame located inside the air cushion will press the bottom surface of the sample preservation tube upward, and push the sample preservation tube upward a distance from the accommodating chamber one or the accommodating chamber two, which is convenient for taking.

[0021] Furthermore, a stop block is provided at the middle of the bottom end of the top cover, facing the center of the accommodating chamber 1 and the accommodating chamber 2. When the top cover is horizontally covered on the top of the box body, the stop block can completely press the contacted sample preservation tube into the accommodating chamber 1 and the accommodating chamber 2.

[0022] Through the above technical solution, the stop block adopts a cross shape and is directly fixed on the bottom surface of the top cover, so that when the top cover is closed, the stop block can be used to press down the sample preservation tube, and the auxiliary connecting frame can flatten the air cushion to reduce the pressure of the arc rod on the lifting frame. The force can be dispersed to avoid damage to the lifting frame and ensure its service life. In the closed state, it can also always press against the top of the sample preservation tube to prevent shaking and impact in the height direction, thereby further improving the buffering protection effect.

[0023] Furthermore, a locking sub-component is provided at a position of the box body corresponding to the lock body, and the lock body is electrically connected to the automatic opener and closer.

[0024] Through the above technical solution, the lock body adopts an electronic lock and can use a contactless unlocking method. This intelligent unlocking method does not require repeated placement of tools and samples, and is more convenient to use. Moreover, after unlocking the lock body and the locking accessories, it can also simultaneously power the reduction motor inside the automatic opener and closeer for automatic closing and opening, and use the motor as the drive for opening and closing and the downward movement of the connecting frame, which is smoother and more convenient.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) The present invention provides a lock body, a support seat, a connecting frame and a limit bar. When taking out or putting in a sample storage tube, the lock body can be unlocked by non-contact induction to automatically open the top cover. After sampling, the hand slides over the lock body to induction lock and automatically close the top cover. The opening and closing process does not require any contact with the shell and the top cover. In particular, formalin can be sealed in the sample collection workshop to reduce its volatilization. The displacement of the connecting frame causes the limit bar to retract and relax the sample storage tube. At the same time, the support seat pushes the sample storage tube out of the accommodating cavity, making it convenient to take out or put in the sample or embedding box.

[0027] (2) The present invention designs a plurality of hexagonal shaped accommodating cavities with common sides in the inner frame through the design of the inner frame, so as to fully utilize the internal space of the box body to accommodate more cylindrical sample storage tubes, and arranges the limit bars in the gaps adjacent to the cylindrical sample storage tubes, so as to utilize the space that cannot be used to store the sample storage tubes to improve the buffering protection for the sample storage tubes, and does not occupy the storage space, so that the structure is more reasonable.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] like Figure 1-Figure 7 As shown, this embodiment provides a sample storage box with intelligent opening and closing, including a box body 1 and a top cover 2. The box body 1 opens upward and is used to store a sample preservation tube 7. The box body is filled with formalin to perform fixed storage of the sample preservation tube 7 (or tissue embedding box). The top cover 2 is movably installed at the top opening of the box body 1 through an automatic opener and closer 4, and can be opened and closed intelligently, that is, a lock body 3 is installed at the joint between the box body 1 and the top cover 2;

[0038] In actual use, the sampling doctor or tester needs to frequently put down the testing and sampling tools, manually open the sample storage box, then pick up the tools to take out the sample storage tube 7 and place it on the sampling or testing table, then put down the sampling tools, manually close the sample storage box to reduce or isolate gas volatilization, and then pick up the tools to further inspect the sample storage tube 7. This solution provides a specific configuration to solve the above practical problems:

[0039] A motion sensor is integrated on the lock body 3. The motion sensor can be an infrared sensor or a photoelectric sensor (an implementation element for contactless waving sensing, and the specific sensing principle is a mature technology and will not be repeated here). It can detect the approach and distance of the tester's hand. When it needs to be opened, the tester can approach the lock body 3 to wave and sense to open the lid. After sampling or storage of the sample preservation tube is completed, the tester can approach the lock body 3 to wave and sense to close the lid. The automatic opener and closer 4 receives the control signal of the lock body 3 and can automatically close the top cover 2. Compared with manual opening and closing of the sample storage box by medical staff, the contactless automatic opening and closing saves a lot of time and is more convenient to use.

[0040] In actual use, because the sample preservation tube 7 is a fragile structure, the sample preservation tube 7 is easily damaged by collision. When the existing storage rack is tightly limited by elastic members, the elastic members are deformed under the inertia of the sample preservation tube 7 when impacted, which will cause adjacent sample preservation tubes 7 to collide with each other. The storage structure of the sample preservation tube 7 that is completely separated will result in low storage space utilization due to more partition structures. When a large number of sample preservation tubes 7 are stored, more storage boxes are required. In order to solve the actual problem, a specific configuration is provided:

[0041] For inner frame 11, refer to Figure 3The inner frame 11 is located in the middle of the box body 1, and the inner frame 11 divides the box body 1 into a receiving chamber 1 12 and a receiving chamber 2 13. In order to reduce the area occupied by the inner frame 11, the receiving chamber 1 12 and the receiving chamber 2 13 are designed to be polygonal and have common edges, so as to make full use of the storage space in the middle of the box body 1, so that more sample storage tubes 7 can be inserted into the receiving chamber 1 12 and the receiving chamber 2 13;

[0042] For limit strip 6, refer to Figure 4 The limiting strip 6 is located at the corner of the accommodating chamber 2 13. Because it is located at the corner, that is, in the gap where the cylindrical sample storage tubes 7 are placed side by side, after the limiting strip 6 is set, it will not affect the arrangement of the accommodating chamber 1 12 and the accommodating chamber 2 13 in the inner frame 11, ensuring the space utilization while providing more stable anti-impact protection. The limiting strip 6 has a cavity 61. The limiting strip 6 is vertically arranged and parallel to the axis of the sample storage tube 7, that is, the limiting strip 6 is a hollow cylinder, which reduces its own weight and has a greater degree of deformation. The exhaust shrinkage can facilitate the insertion and removal of the sample storage tube 7, and the inflation expansion can provide contact protection for the sample storage tube 7 from the radial direction. The specific flushing and deflation structure is not limited here.

[0043] Regarding the support 9, refer to Figure 2 The support seat 9 is located at the bottom of the accommodating chamber 13, and can support the sample storage tube 7 from the bottom to protect the weak bottom position of the sample storage tube 7. The support seat 9 includes a hollow air cushion 91. There is air inside the air cushion 91, which has a larger space for buffering deformation and has the effect of absorbing impact force.

[0044] For Lianjia 8, refer to Figure 6 and Figure 7 The connecting frame 8 includes a U-shaped main body 81, one end of which is mounted at the central axis of the limiting strip 6, and the other end is mounted at the central axis of the air cushion 91, and the main body 81 is built with a connecting hole 84 connecting the cavity 61 and the air cushion 91 to connect the two. When in use, if the sample storage tube 7 is inserted, the end of the connecting frame 8 will be squeezed to move downward, which can flatten the air cushion 91, so that the gas therein enters the cavity 61, and the flexible limiting strip 6 will expand radially due to inflation, and contact the vertical side wall of the sample storage tube 7. The air cushion 91 serves as the air source for inflating the limit strip 6. There is no need to design a separate air supply device, and the structure is simple. The flattening of the air cushion 91 and the limit strip 6 are performed synchronously, so it is easy to use. Similarly, when it is necessary to extract the sample preservation tube 7, the connecting frame 8 moves upward, so that the air cushion 91 is stretched vertically to increase the internal space, and the air inside the limit strip 6 flows into the air cushion 91 and becomes deflated, which can shorten the outer diameter of the limit strip 6 and detach it from the sample preservation tube 7, making it convenient and smooth to use. Compared with the elastic parts that are always clamped, there is no problem of elastic fatigue and inconvenience of clamping too tightly and pulling out.

[0045] In a further embodiment, referring to Figure 3, the accommodating chamber 12 and the accommodating chamber 2 13 are both regular hexagonal cavities. In order to make full use of the internal space of the box body 1, the inner frame 11 can divide the interior of the box body 1 into a honeycomb shape, so that the accommodating chamber 12 and the accommodating chamber 2 13 can be designed with a common edge, ensuring that the accommodating chamber 12 and the accommodating chamber 2 13 have fully wrapped vertical side walls, while reducing the total number of side edges, simplifying the structure of the inner shell 11, and the hexagonal positions of the accommodating chamber 2 13 are all provided with limiting strips 6, and the accommodating chamber 1 12 is only provided with limiting strips 6 at the corner positions that share the same edge with the accommodating chamber 2 13, and the limiting strips 6 are arranged at the hexagons of the accommodating chamber 2 13, and the sample storage tube 7 in the accommodating chamber 2 13 is fully wrapped and limited by the six limiting strips 6. Protection, it can be used to place sample storage tubes 7 with specimens, and the accommodating chamber 1 12 also has limit strips 6 at the four corners to ensure basic protection effect, and can be used to place empty sample storage tubes 7. The concave and convex shapes around the inner frame 11 caused by the hexagonal prism shape of the accommodating chamber 1 12 and the accommodating chamber 2 13 will form a buffer space with the side walls of the box body 1 to reduce the impact damage of external impact on the internal sample storage tube 7. The inner frame 11 is provided with an installation groove 14 corresponding to the position of the limit strip 6. The installation groove 14 allows the limit strip 6 to be accommodated in the fixed gap formed by the curved side walls of the adjacent sample storage tubes 7, and will not occupy the effective accommodation space, thereby improving the space utilization rate of the equipment.

[0046] In a further embodiment, referring to Figure 2 , Figure 6 and Figure 7 The support seat 9 includes a base 93. When the air cushion 91 is installed, the base 93 suspends the air cushion 91 and leaves sufficient space for the installation and up and down movement of the main body 81. The base 93 is located at the bottom of the air cushion 91. A flat plate 92 is fixedly installed on the inner wall of the top of the air cushion 91. The flat plate 92 is fixedly connected to one end of the main body 81 located on the inner side of the air cushion 91. When in use, the flat plate 92 is arranged on the top surface of the air cushion 91. When the main body 81 moves downward, the air cushion 91 can be flattened in cooperation with the base 93, so that the sample preservation tube 7 can move downward and be completely inserted into the accommodating chamber 1 12 or the accommodating chamber 2 13. After the air cushion 91 is flattened, the air inside will enter the cavity 61 from the connecting hole 84. The limiting strip 6 is designed as an elastic thin-walled structure. After the gas enters, the outer diameter of the limiting strip 6 can be enlarged due to inflation. In addition, the limiting strip 6 is arranged in parallel with the sample preservation tube 7. The inflated limiting strip 6 can further squeeze the sample preservation tube 7 for buffering, thereby improving the buffering effect.

[0047] In a further embodiment, referring to Figure 5 and Figure 6The limit strip 6 is sleeved on one end of the main body 81 located at the mounting groove 14. The limit strip 6 adopts a hollow ring shape and is coaxially sleeved and fixed on the vertical section of the main body 81, so that the flexible limit strip 6 can be kept vertical. When the sample preservation tube 7 is inserted, the limit strip 6 that has not been inflated by the air cushion 91 can be prevented from rubbing against the lower part of the sample preservation tube 7 due to friction, so that the limit strip 6 can be kept as high as possible with the sample preservation tube 7. The end of the main body 81 extends a distance above the limit strip 6. The inner frame 11 is located directly above the limit strip 6 and is provided with a guide hole 15 that cooperates with the main body 81. The movable end of the main body 81 is inserted into the guide hole 15. Even if the limit strip 6 is inflated to squeeze the sample preservation tube 7, axial deviation will not occur because there is no sample preservation tube 7 in the adjacent accommodating chamber 1 12 or the accommodating chamber 2 13 to squeeze the limit strip 6. This ensures that a small amount of sample preservation tubes 7 can still be stably buffered and protected when the sample preservation tube 7 is not full.

[0048] In a further embodiment, referring to Figure 6 and Figure 7 , a top block 82 is installed at the top of the limit bar 6, and the downward movement of the main body 81 can drive the top block 82 downward, and the limit bar 6 is pressed down by the cone-shaped top block 82 with a thick top and a thin bottom, so that the top of the limit bar 6 is concave and extruded into a reduced diameter portion 1 62, and a bottom block 83 is installed at the bottom of the limit bar 6. The bottom block 83 is fixed to the lower part of the inner frame 11, and the bottom block 83 is slidably connected to the main body 81. When the main body 81 drives the limit bar 6 downward, a middle hole with a thick top and a narrow bottom is provided in the middle of the bottom block 83. The inner wall of the middle hole of the bottom block 83 can extrude the bottom of the limit bar 6 into a reduced diameter portion 2 63, and the top block 82 and the main body 81 are connected. The bottom block 83 is fixedly connected to the inner frame 11, and a through hole cooperating with the main body 81 is provided in the middle of the bottom block 83. Such a design allows the limit strip 6 to be clamped from both ends, and the internal space of the limit strip 6 is significantly reduced. The limit strip 6 can be squeezed by the top block 82 and the bottom block 83 to expand radially, that is, the limit strip 6 can be deformed and squeezed between the sample preservation tube 7 and the inner frame 11 to form a side convex portion 64, thereby increasing the wrapping contact area for the sample preservation tube 7, and also increasing the supporting strength, thereby reducing the radial shaking of the sample preservation tube 7 and the collision with the inner wall of the inner frame 11 when a large force is impacted horizontally.

[0049] In a further embodiment, referring to Figure 2 and Figure 3, the connecting frames 8 are connected by the lifting frame 5, and the lower part of the lifting frame 5 adopts a horizontal frame structure, which can fix all the connecting frames 8 into a whole, wherein the top of the lifting frame 5 extends upward over the top surface of the inner frame 11, and the external force can be easily applied to the connecting frame 8 through the lifting frame 5, so as to drive the connecting frame 8 up and down. Specifically, the arc rod 21 is installed at the position where the top cover 2 is opposite to the lifting frame 5. When the top cover 2 is horizontally covered on the top of the box body 1, the arc rod 21 is fully inserted into the inclined hole 51, and the root of the arc rod 21 will contact and press down the lifting frame 5, so that the lower dead point of the downward movement of the connecting frame 8 is the pressure. The flat air cushion 91 provides driving force for inflating the limit strip 6. When the top cover 2 swings and unfolds, the top cover 2 drives the arc rod 21 to move synchronously, and can pull the arc rod 21 upward from the inclined hole 51. The friction force of the contact surface between the arc rod 21 and the inclined hole 51 drives the lifting frame 5 and the connecting frame 8 upward, so that the limit strip 6 is stretched and reduced in diameter, and the internal gas returns to the air cushion 91. In addition, the end of the connecting frame 8 located inside the air cushion 91 will squeeze the bottom surface of the sample preservation tube 7 upward, and push the sample preservation tube 7 upward out of the accommodating chamber 1 12 or the accommodating chamber 2 13 for a distance, which is convenient for taking.

[0050] In a further embodiment, referring to Figure 2 and Figure 3 A stopper 22 is provided at the middle of the bottom end of the top cover 2, facing the center of the accommodating chamber 1 12 and the accommodating chamber 2 13. The stopper 22 is cross-shaped and is directly fixed to the bottom surface of the top cover 2. In this way, when the top cover 2 is closed, the stopper 22 can be used to press down the sample preservation tube 7, and the auxiliary connecting frame 8 can flatten the air cushion 91, thereby reducing the pressure of the arc rod 21 on the lifting frame 5. The force dispersion can avoid damage to the lifting frame 5 and ensure its service life. In the closed state, it can also always press against the top of the sample preservation tube 7 to prevent shaking and impact in the height direction, thereby further improving the buffer protection effect.

[0051] In a further embodiment, referring to Figure 1 and Figure 3 , a lock body 3 is installed at the joint of the box body 1 and the top cover 2. The lock body 3 adopts an electronic lock and can use a non-contact unlocking method of waving induction. This intelligent unlocking method is more convenient and safe. The hands do not need to touch the storage box throughout the whole process, and there is no need to frequently pick up and put tools. It can also prevent the box body 1 from being exposed for a long time due to the inconvenience of closing, causing formalin to escape. The lock body 3 is hinged to the top cover 2, and a locking sub-part is provided at the position of the box body 1 corresponding to the lock body 3. The lock body 3 is electrically connected to the automatic opener and closer 4. After the unlocking lock body 3 is separated from the locking sub-part, the lock body 3 can also send a control signal to enable the control device (a single-chip microcomputer with a battery can be used, installed in the top cover 2 or the box body 1, not shown in the figure) to power the reduction motor inside the automatic opener and closer 4 for automatic closing and automatic opening, and the motor is used as the opening and closing and the downward drive of the connecting frame 8, which is smoother and more convenient.

[0052] The working principle of this embodiment is as follows:

[0053] When the sample storage tube 7 needs to be stored, a new storage box is taken out, the lock body 3 is opened by non-contact waving induction, and the automatic opener and closer 4 drives the top cover 2 to unfold. When the top cover 2 is unfolded, the arc rod 21 rubs the lifting frame 5 to lift the connecting frame 8, so that the air cushion 91 and the limiting strip 6 are stretched in the vertical direction, and the air in the limiting strip 6 enters the air cushion 91, so that the limiting strip 6 becomes deflated and retracts into the installation groove 14, and the preliminary preparation for storage is automatically completed, so that the accommodating chamber 1 12 and the accommodating chamber 2 13 are fully opened, which is convenient for the insertion of the sample storage tube 7;

[0054] After all the sample storage tubes 7 are inserted, the top cover 2 is closed, and the arc rod 21 presses down the lifting frame 5 to move the connecting frame 8 downward. At the same time, the stop block 22 presses the sample storage tube 7 into the accommodating chamber 1 12 or the accommodating chamber 2 13, and the air cushion 91 is flattened. The air inside enters the limiting strip 6, and the limiting strip 6 is squeezed by the top block 82 and the bottom block 83 to expand radially, and deform and squeeze between the sample storage tube 7 and the inner frame 11 to form a side convex portion 64, which wraps and protects the vertical side wall of the sample storage tube 7;

[0055] Because the hexagonal prism shape of the accommodating chamber 1 12 or the accommodating chamber 2 13 , a buffer gap is formed between the inner frame 11 and the vertical side wall of the box body 1 , which can accommodate formalin;

[0056] When taking out the sample preservation tube 7, the lock body 3 opens the top cover 2 by waving the hand, and the automatically opened top cover 2 can also drive the lifting frame 5 to lift the connecting frame 8 by friction, so that the air in the limiting strip 6 can flow back into the air cushion 91, and the limiting strip 6 becomes deflated and retracts into the installation groove 14, breaking away from the vertical side wall of the sample preservation tube 7. The expansion of the air cushion 91 and the upward movement of the connecting frame 8 cause the sample preservation tube 7 to be pushed upward out of the accommodating chamber 1 12 or the accommodating chamber 2 13 for a distance, so that it is convenient to use a tool to clamp the top of the sample preservation tube 7 for removal, and then the hand slides across the position of the lock body 3 to perform non-contact locking, thereby isolating the diffusion and volatilization of formalin, which is convenient to use.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
