Description

Technical Field

[0001] The present disclosure relates to the technical field of mechanical equipment, and particularly relates to a push-pull storage structure, an incubator and a cell workstation. Background Art

[0002] A cell workstation is a device system used in technical fields such as biology and medicine, which may include biological cell operation devices such as a sterile isolator. Among them, a sterile isolator is a scientific instrument used in the fields of basic medicine and clinical medicine. Since it can provide a sterile environment for sterile products, operators can operate on the products in the sterile environment through isolator gloves, etc., so that the sterile treatment can be maintained during the processing of these products, and direct contact between the operator and the articles can be fundamentally avoided. Therefore, the test samples and auxiliary facilities can be avoided from being contaminated during sterile inspection. Generally, sterile products (such as cultures) are usually placed in an incubator for cultivation. The incubator mainly simulates and forms a growth environment similar to that of cells / tissues / microorganisms in vivo or in a certain specific situation in the incubator chamber, such as temperature, humidity, etc. Therefore, the incubator is an indispensable laboratory device for scientific research departments such as plants, microorganisms, and genetics, and is widely used in low-temperature constant temperature tests, cultivation tests, environmental tests, etc.

[0003] There are already two typical incubators used in combination with cell workstations in the prior art. One is a small incubator with a relatively small volume, about 50-70L, and the internal cultivation space is small. It can be directly taken and placed during use, but the number of cultured cell products that can be placed is small. Moreover, in the operation of taking and placing the cultured products, due to the limited length of the human arm, there is a problem that it is impossible to effectively take the cultures outside the arm length range, and it is inconvenient to use; the other is a large-scale highly automated carbon dioxide incubator, which can be configured with corresponding robotic arms or transmission mechanisms inside. Although it can provide large-scale and centralized accommodation of cultures, its processing accuracy requirements are relatively high and the cost is extremely high, which greatly limits its application in scenarios such as laboratories.

[0041] To solve the technical problem in the prior art that the incubator in the cell workstation cannot effectively balance cost and convenience of loading and unloading, the present disclosure provides a push-pull storage structure, an incubator, and a cell workstation with extremely low cost and convenient loading and unloading operations.

[0042] As Figures 1 - 11 shown, one aspect of the present disclosure provides a push-pull storage structure 4, which includes a frame body 41, a rail body 42, and a push-pull body 43.

[0043] The frame body 41 has a push-pull end;

[0044] In the static state, the rail body 42 is hung on the pushing and pulling end of the frame body 41. In the pushing and pulling state, the rail body 42 is arranged below the frame body 41, and the frame body 41 can move along the rail body 42; and

[0045] In the static state, the pushing and pulling body 43 corresponds to the rail body 42 and is connected to the frame body 41 in a mating manner with the end face of the pushing and pulling end of the frame body 41. In the pushing and pulling state, the pushing and pulling body 43 is connected to the frame body 41 in a mating manner with the lower surface corresponding to the pushing and pulling end of the frame body 41.

[0046] The pushing and pulling storage structure 4 is mainly used for placing load-bearing objects, which can include various storage products or culture products, etc. The pushing and pulling storage structure 4 can have at least two states: the static state and the pushing and pulling state. Among them, in the static state, the pushing and pulling storage structure 4 is basically in the original position and basically does not change in position and shape; in the pushing and pulling state, the pushing and pulling storage structure 4 can be pulled out from the original position to the picking and placing position by an external pulling force, so that technicians, robotic arms, etc. can conveniently pick and place the load-bearing objects placed on the pushing and pulling storage structure 4. Correspondingly, in the pushing and pulling state, the pushing and pulling storage structure 4 can also be pushed back from the picking and placing position to the original position by an external pushing force for static storage of the load-bearing objects.

[0047] The frame body 41 is a frame structure with a certain rigidity, with a hollow main body, but corresponding support frameworks will be provided as the main body for other structural elements to be attached. At the same time, the support frameworks are not easily deformed and can provide a setting structure for the load-bearing objects. In addition, the frame body 41 will have two corresponding ends in the length direction or in the pushing and pulling direction formed by the connection line between the original position and the picking and placing position, and the end that is subjected to the pushing force and the pulling force among the two ends is the pushing and pulling end.

[0048] The rail body 42 is a guide rail structure and has the function of guiding the frame body 41 to move in the direction defined by the guide rail structure. The rail body 42 can be hung on the pushing and pulling end of the frame body 41 in the static state. The hanging can be a hanging effect that can be manually taken and hung at any time, as long as the rail body 42 can be stable on the frame body 41 in the static state. In addition, in the pushing and pulling state, the rail body 42 is located between the original position and the picking and placing position of the frame body 41. At this time, the rail body 42 is in movable contact with the frame body 41 below the frame body 41. One end of the rail body 42 facing the pushing and pulling end corresponds to the picking and placing position, and the other end of the rail body 42 facing away from the pushing and pulling end corresponds to the original position. Moreover, during this period, the frame body 41 can be guided along the rail body 42. When the frame body 41 is subjected to a pulling force, the frame body 41 can move from the original position to the picking and placing position along the guidance of the rail body 42. When the frame body 41 receives a pushing force, the frame body 41 can move back from the picking and placing position to the original position along the guidance of the rail body 42.

[0049] The push-pull body 43 is movably connected to the push-pull end of the frame body 41. In the static state, the push-pull body 43 can correspond to the rail body 42 hung on the frame body 41 and is movably connected to the frame body 41 in cooperation with the end face of the push-pull end. At this time, the push-pull body 43 will not be affected by external thrust or pulling force. In the push-pull state, the push-pull body 43 cooperates with the lower surface of the frame body 41 corresponding to the push-pull end and is movably connected to the frame body 41. At this time, when the push-pull body 43 is subjected to an external pulling force, it will drive the push-pull end of the frame body 41 to be subjected to a pulling force, and the frame body 41 located on the rail body 42 will be pulled to move from the original position to the picking and placing position along the guidance of the rail body 42. On the contrary, the push-pull body 43 can also be subjected to an external thrust, and at this time, it will drive the push-pull end of the frame body 41 to be subjected to a thrust, and the frame body 41 located on the rail body 42 will be pushed to move from the picking and placing position to the original position along the guidance of the rail body 42.

[0050] Therefore, with the above-mentioned push-pull storage structure, more convenient picking and placing operations for carriers such as cultures can be provided in storage spaces such as incubators, solving the problem of ineffective picking of cultures caused by limited arm length. Moreover, the structure is very simple, can meet relatively low processing precision, and makes the overall preparation cost extremely small.

[0051] As Figures 1 - 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 11 shown, according to an embodiment of the present disclosure, the frame body 41 includes at least one fixed position 41a, at least one hanging position 41b, at least one guiding position 41c, at least one caster and at least one movable position.

[0052] At least one fixed position 41a is arranged on the upper surface of the frame body 41 for placing objects;

[0053] At least one hanging position 41b is arranged on the edge of the upper surface of the frame body 41 close to the push-pull end for hanging the rail body 42;

[0054] At least one guiding position 41c is arranged on at least one side surface of the frame body 41 for positioning and guiding the movement of the frame body 41 along the rail body 42 in the push-pull state;

[0055] At least one caster is arranged below the edge of the lower surface of the frame body 41;

[0056] At least one movable position is symmetrically arranged on the edge of the lower side of the push-pull end with respect to the end face of the push-pull end, and movably connects the push-pull body 43 and the frame body 41.

[0057] Each of the at least one fixing position 41a can be a fixed structure or a fixing hole provided on the upper surface of the frame body 41. Among them, the at least one fixing position 41a can be directly used to fix the carrier itself to achieve object placement, or can be used to fix the structural body for placing the carrier to achieve object placement, specifically such as the object placement table 5 described later. Among them, in the case of preventing the object placement table 5, the plurality of fixing positions 41a can provide a more stable placement effect for the object placement table 5, prevent the object placement table 5 from rotating or shaking relative to the frame body 41, etc., and avoid the carrier from falling off or tipping over during the movement process.

[0058] At least one hanging position 41b is provided at the intersection position of the upper surface of the frame body 41 and the end surface of the pushing and pulling end, and specifically can be located at the edge of the upper surface of the frame body 41. Each hanging position 41b can specifically be a hanging hole, and the rail body 42 can be hung in cooperation with the hanging hole in a static state. In addition, the hanging position 41b can also be a hanging protrusion (such as a hanging hook, a hanging post, etc.), that is, protruding from the upper surface of the frame body 41 along the end surface of the pushing and pulling end of the frame body 41, so that the rail body 42 can be hung. Among them, the number of the hanging positions 41b can be at least 2 to improve the hanging stability of the rail body 42 and prevent abnormal vibration, shaking, etc.

[0059] The specific number of the at least one guiding position 41c can be 2, or can be more than 2. Among them, an even number of guiding positions 41c can generally be symmetrically arranged along the side surfaces on both sides of the frame body 41. The symmetrically arranged guiding positions 41c can guide the movement of the frame body 41 along the rail body 42 in the pushing and pulling state relative to both sides of the frame body 41, which is beneficial to the frame body 41 to smoothly make guiding contact with the rail body 42. In addition, if the storage space for placing the push-pull storage structure 4 has guiding rails matched with the positions corresponding to the guiding positions 41c on its inner wall surface, it can also guide the movement of the push-pull storage structure 4 in the storage space in the pushing and pulling state, so as to facilitate its smooth entry and exit from the storage space. Essentially, it is still to position and guide the movement of the frame body 41 along the rail body 42 in the pushing and pulling state. Among them, the specific number of the guiding positions 41c can also be an odd number of one or more. It should be noted that the guiding position 41c is located at the rear edge of the side surface of the frame body 41 and can form an inclined chamfer to play a guiding role when the whole frame body 41 enters the storage space. Among them, the storage space can be constituted by an incubator for storing the push-pull storage structure 4, etc.

[0060] At least one caster may include 2 front casters 41e and 2 rear casters 41d. The casters can achieve the moving contact between the frame body 41 and the rail body 42. Each caster can move directionally between the original position and the picking and placing position along the rail body 42 in the pushing and pulling state, so as to drive the entire push-pull storage structure 4 to move between the original position and the picking and placing position. Among them, the number of casters can be adjusted accordingly according to the supporting effect of the storage space on the two side surfaces of the frame body 41 and the number of guide rails of the rail body 42, and can be, for example, Figures 1 - 3 , Figure 5 , Figure 6 , Figure 7 and Figure 11 as shown, which is 4, or there can be only 1 caster.

[0061] The movable position can be the mating and fixing part of the rotational connection structure, such as the shaft hole fixed on the lower side edge of the pushing and pulling end of the frame body 41; the pushing and pulling body 43 also needs to have the mating and rotating part of the rotational connection structure that mates with the mating and fixing part of this movable position, such as the rotating shaft matching the above shaft hole, so as to enable the pushing and pulling body 43 and the frame body 41 to be movably connected, and in the pushing and pulling state, enable the pushing and pulling body 43 to rotate relative to the frame body 41, so as to cooperate with the lower surface of the frame body 41 corresponding to the pushing and pulling end and be movably connected to the frame body 41. At this time, when an external pulling force is applied to the pushing and pulling body 43, it will drive the pushing and pulling end of the frame body 41 to be subjected to the pulling force, and the frame body 41 located on the rail body 42 is pulled to move from the original position to the picking and placing position along the guidance of the rail body 42. On the contrary, the pushing and pulling body 43 can also be subjected to an external pushing force. At this time, it will drive the pushing and pulling end of the frame body 41 to be subjected to the pushing force, and the frame body 41 located on the rail body 42 is pushed to move from the picking and placing position to the original position along the guidance of the rail body 42. The number of movable positions is generally 2, which can not only ensure the stability of the movable connection but also simplify the structural composition.

[0062] For example, Figures 1 - 4 , Figure 7 and Figure 11 as shown, according to the embodiments of the present disclosure, the rail body 42 includes at least one track member 42e and a fixing member 42d.

[0063] Each track member 42e in at least one track member 42e has a track that matches the corresponding caster in at least one caster, so that in the pushing and pulling state, the frame body 41 can move along the rail body 42 according to the matching of the corresponding caster and the track;

[0064] The fixing member 42d fixes at least one track member 42e and is hung with the pushing and pulling end of the frame body 41 in the static state.

[0065] Each track member 42e has a track for corresponding movement guidance. Each track matches the unilateral caster in the caster and can be in contact with the unilateral caster in the pushing and pulling state, so that the unilateral caster (such as Figure 1The front caster 41e and the rear caster 41d shown can be in contact with the track of the track member 42e and move guided along the track. Among them, the track can be designed as an inward concave long groove or an outward convex long strip, and the corresponding caster has a contact structure design that matches the corresponding inward concavity and outward convexity, so that it is not easy to derail when moving in contact with the track.

[0066] The fixing member 42d is used to fix the track member 42e. Especially in the case of two or more track members 42e, the fixing member 42d can fixedly connect two or more track members 42e, and can be specifically arranged below each track member 42e to avoid affecting the upper track. The fixing method can be riveting or integral molding design. The fixing member 42d can provide better structural stability for the entire track body 42, prevent the frame 41 from shaking during the movement of the frame 41 relative to the track body 42 in the pushing and pulling state, avoid derailment, and also help the track body 42 to be stably hung on the frame 41 as a whole in the static state.

[0067] Among them, the overall shape of the track member 42e can be adjusted according to the planes where the original position and the pick-up and placement position are located, and it is not a strictly straight track body design, and no specific restrictions are made here. It should be noted that the planes where the original position and the pick-up and placement position are located can be the same plane.

[0068] As Figures 1 - 4 、 Figure 7 and Figure 11 shown, according to an embodiment of the present disclosure, each track member 42e of at least one track member 42e includes a limit post 42b and a limit slope 42c.

[0069] The limit post 42b is arranged on the lower surface of the track, near the movement stop end of the track member 42e;

[0070] The limit slope 42c is arranged on the upper surface of the track, at the movement start end of the track member 42e.

[0071] The limit post 42b is arranged on the back surface of each track member 42e, generally protruding from the back surface of the track member 42e, and can be specifically located on the lower surface of the track of the track member 42e. Among them, in the pushing and pulling state, the limit post 42b can be fixed on the plane 14 where the pick-up and placement position is located to enhance the structural stability during the pick-up and placement of the load, and also prevent the track body 42 from being affected by the frictional force between the track body 42 and the frame 41 (generated by the external thrust or pull on the frame 41) and other factors, resulting in the movement of the track body 42 along with the movement of the frame 41, and at the same time, it also avoids the lateral tilting and toppling of the track body 42.

[0072] One end of the rail member 42e facing the pick-and-place position is the moving stop end. When carrying out the picking and placing of the load in the pushing and pulling state, the front caster 41e of the frame 41 can stop on the plane 14 where the pick-and-place position corresponding to the moving stop end is located; the other end of the rail member 42e facing the original position is the moving start end. In the static state, the front caster 41e of the frame 41 can stop at this moving start end. When carrying out the picking and placing of the load in the pushing and pulling state, the rear caster 41d of the frame 41 can stop at this moving start end to prevent the frame 41 from continuing to move forward along the track of the rail member 42e.

[0073] Among them, the position of the limiting post 42b on the back surface of each rail member 42e is close to the moving stop end of the rail member 42e, but generally not set at this moving stop end. When the rail body 42 is set on the plane 14 where the pick-and-place position is located, the rail body 42 can have a stable setting effect with this plane and is not easily shaken when the frame 41 moves along the rail body 42. In addition, a plurality of limiting posts 42b can be simultaneously arranged and distributed on the back surface of each rail member 42e to further strengthen the stable combination effect between the rail body 42 and the plane 14 of the pick-and-place position. Of course, if the number of rail members 42e is large, one limiting post 42b can also be set on each rail member 42e. Correspondingly, there is no need to separately set a limiting post on the rail member 42e corresponding to the plane where the original position is located.

[0074] In the pushing and pulling state, the limiting slope 42c is set at the moving start end of the rail member 42e. The limiting slope 42c has an upward inclination angle relative to the plane where the original position is located, and this angle is an acute angle, so that the limiting slope 42c is a slope formed by inclining at an acute angle upward from the plane where the original position is located through the moving start end to the upper part of the rail member 42e. By this means, it can prevent the frame 41 from continuing to move along the rail body 42 towards the plane 14 where the pick-and-place position is located, and limit the frame 41 that moves under tension to the best position where it can be convenient for picking and placing and will not affect other non-picking and placing operations. It should be noted that in the pushing and pulling state, if the pulling force on the pushing and pulling end of the frame 41 is too large, the rear caster 42d of the frame 41 can also be pulled onto this limiting slope 42c, so that the rear caster 42d of the frame 41 is pulled onto the rail member 42e, and finally the rear caster 42d moves to the plane 14 where the pick-and-place position is located.

[0075] As Figures 1 - 4 、 Figure 7 and Figure 11 shown, according to an embodiment of the present disclosure, the fixing member 42d includes at least one hanging member 42a.

[0076] At least one hanging member 42a is located on the lower side surface of the fixing member 42d facing the moving start end of the rail member 42e in the static state and is correspondingly hung with at least one hanging position 41b of the frame 41.

[0077] On the fixing member 42d, a hanging member 42a that can be matched and hung corresponding to the hanging position 41b of the aforementioned frame body 41 can be provided. The structural design of each hanging member 42a is matched with the structural design of the corresponding hanging position 41b. Specifically, when the hanging position 41b is a hanging hole, the corresponding hanging member 42a can be a hanging protrusion that matches the hanging hole, such as a hanging hook, a hanging post, etc. In addition, its structural design can also be designed conversely, that is, the hanging position 41b is a hanging protrusion, and the hanging member 42a is a hanging hole penetrating through the fixing member 42d. As Figure 4 shown, the hanging member 42a can protrude downward along the lower side surface of the fixing member 42d in the static state, so that the hanging member 42a can be hung at the matching hanging position 41b in the static state. Therefore, in the static state, the rail body 42 can be stably hung on the frame body 41 generally parallel to the end face of the pushing and pulling end of the frame body 41 as a whole, so as to save the installation space, ensure that the rail body 42 can be used at any time as an accessory detachable from the frame body 41 to realize the moving guiding function of the rail body 42, and the structural form is very simple and compact, which is beneficial to saving the manufacturing cost and improving the use convenience. Among them, the number of the hanging members 42a and the hanging positions 41b can be kept the same to match the hanging and form a relatively stable hanging effect, preventing abnormal shaking, vibration, etc. from causing abnormal detachment of the rail body 42 and the frame body 41 in the static state.

[0078] As Figure 1 、 Figure 3 、 Figures 5 - 7 and Figure 11 shown, according to an embodiment of the present disclosure, the pushing and pulling body 43 includes a pushing and pulling member 43a, a supporting member 43b, and a connecting member 43d.

[0079] The pushing and pulling member 43a is arranged at the holding end of the pushing and pulling body 43 and is used to provide a holding part for pushing and pulling the pushing and pulling body 43;

[0080] The supporting member 43b is arranged at the supporting end of the pushing and pulling body 43 corresponding to the pushing and pulling member 43a and is used to support the pushing and pulling body 43 in the static state; and

[0081] The connecting member 43d connects the pushing and pulling member 43a and the supporting member 43b, and as the main structure of the pushing and pulling body 43, it cooperates with the end face of the pushing and pulling end of the frame body 41 in the static state, and the part of the connecting member 43d close to the supporting end cooperates with the corresponding lower surface of the pushing and pulling end of the frame body 41 in the pushing and pulling state.

[0082] The pushing and pulling member 43a can serve as the gripping end of the pushing and pulling body 43, used to provide a gripping or grasping part to provide a pushing force or a pulling force in the pushing and pulling state. Specifically, the pushing and pulling member 43a can be two horizontally arranged tie rods designed to be parallel to each other, with a certain distance between the two horizontally arranged tie rods, so as to provide a more secure pushing, pulling or pulling force application part in a relatively simple structural form, facilitating gripping and grasping. Among them, in the static state, the end face of the pushing and pulling member 43a parallel to the pushing and pulling end of the frame body 41 and the whole pushing and pulling body 43 are located in front of the end face, and the vertical height is higher than the upper surface of the frame body 41; in the pushing and pulling state, the pushing and pulling member 43a is located in front of the end face of the pushing and pulling end of the frame body 41, and the vertical height is lower than the lower surface of the frame body 41.

[0083] The support member 43b can serve as the support end of the pushing and pulling body 43 and can be a horizontal support rod. In the static state, the support member 43b is in contact with the plane where the original position is located, so as to support the whole frame body 41 by supporting the pushing and pulling body 43, preventing the frame body 41 from moving forward, backward, left or right due to abnormal reasons such as vibration and shaking or external forces. In the pushing and pulling state, the support member 43b is separated from the plane where the original position is located and abuts against the lower surface of the frame body 41, thus avoiding the situation that the normal movement of the frame body 41 caused by the pushing force or the pulling force is affected due to the contact between the support member 43b and the plane where the corresponding original position is located.

[0084] The connecting member 43d serves as the main structure of the whole pushing and pulling body 43 and can be two parallel rod structures that connect the two ends of the pushing and pulling member 43a and the two ends of the support member 43b respectively, used to connect the pushing and pulling member 43a and the support member 43b. In the static state, the connecting member 43d abuts against the end face of the pushing and pulling end of the frame body 41 and can be attached to the position between the end face and the rail body 42 as a whole nearly parallel, so as to save the installation space as much as possible and make the whole pushing and pulling storage structure 4 have a more compact structural design. In the pushing and pulling state, the connecting member 43d abuts against the lower surface of the frame body 41 and can be attached to the lower surface as a whole nearly parallel. At this time, the rail body 42 is laid under the frame body 41 and contacts the casters of the frame body 41. Therefore, the stable support of the support member 43b for the frame body 41 can be released. When the pushing and pulling member 43a is subjected to a pushing force or a pulling force, by virtue of the fixed connection between the connecting member 43d and the support member 43b and the pushing and pulling member 43a, the frame body 41 movably connected to the pushing and pulling body 43 can generate a traction force to move to the original position or the picking and placing position due to the pushing force or the pulling force, and is pushed to the original position or pulled to the picking and placing position.

[0085] As Figure 3 、 Figure 5 and Figure 6 shown, according to an embodiment of the present disclosure, the pushing and pulling body 43 further includes at least one movable member 43c.

[0086] At least one movable member 43c is movably connected to at least one movable position of the frame body 41 in a one-to-one correspondence, and is symmetrically fixed to the connecting member 43d with respect to the end face of the pushing and pulling end, and the connecting member 43d of the movable pushing and pulling body 43 is movably connected to the pushing and pulling end of the frame body 41.

[0087] The movable connection between the pushing and pulling body 43 and the frame body 41 is realized by at least one movable member 43c of the pushing and pulling body 43 and a movable position on the frame body 41 that is set in one-to-one matching with it. Among them, the movable member 43c can be a rotating shaft structure, which is fixed inside or outside the connecting member 43d of the pushing and pulling body 43. At the same time, at the intersection edge between the end face and the lower surface of the pushing and pulling end of the frame body 41, a bushing that is mutually matched with the rotating shaft structure is fixed corresponding to the movable member 43c as the movable position. Among them, the structural settings of the movable member 43c and the movable position can be interchanged, that is, the movable member 43c is a bushing fixed on the connecting member 43d, and the movable position is a rotating shaft structure fixed at the corresponding position on the frame body 41, specifically as Figure 5 shown in 43c.

[0088] Among them, the movable member 43c fixed on the connecting member 43d and the movable position of the frame body 41 can cooperate with each other to realize the rotation of the two, such as the rotation between the movable bushing and the fixed rotating shaft structure, or the rotation between the movable rotating shaft structure and the fixed bushing. Thereby, during the conversion process from the static state to the pushing and pulling state, the pushing and pulling body 43 can realize the rotation of the pushing and pulling body 43 from abutting against the end face of the pushing and pulling end of the frame body 41 in the static state to abutting against the lower surface of the frame body 41 by means of the rotational cooperation between the movable member 43c and the movable position on the frame body 41, so that the support member 43b of the pushing and pulling body 43 is separated from the contact between the planes where the original positions are located, and the whole of the pushing and pulling body 43 is almost parallel to the lower surface of the frame body 41, thereby ensuring that the pushing and pulling of the pushing and pulling member 43a of the pushing and pulling body 43 in the pushing and pulling state can stably drive the whole pushing and pulling of the frame body 41.

[0089] Among them, the movable member 43c is symmetrically arranged relative to the connecting member 43d, and the movable position matches its position, so as to ensure stable mutual rotation between the two, so as to form a connecting rotation fulcrum of the push-pull body 43. Among them, in the static state, the whole connecting member 43d and the end face of the push-pull end of the frame body 41 are kept in contact as much as possible, so that this end face can limit the rotation angle of the connecting member 43d relative to the movable position and the movable member 43c in the counterclockwise or clockwise direction (specifically determined according to the angle observed by those skilled in the art). On the contrary, in the push-pull state, the whole connecting member 43d and the lower surface of the frame body 41 are kept in contact as much as possible, so that this lower surface can limit the rotation angle of the connecting member 43d relative to the movable position and the movable member 43c in the clockwise or counterclockwise direction. In this way, the structural relationship between the push-pull body 43 and the frame body 41 can be made more stable in the static state and the push-pull state. Among them, the contact support of the support member 43b is also required for assistance in the static state, and the gravity of the push-pull member 43a is also required in the push-pull state. Therefore, taking the position of the movable member 43c on the connecting member 43d as the boundary, the length of the connecting member 43d between the movable member 43c and the push-pull member 43a is greater than the length of the connecting member 43d between the movable member 43c and the support member 43b.

[0090] As Figure 3 and Figure 6 shown, according to an embodiment of the present disclosure, the connecting member 43d includes a curved body 43d0.

[0091] The curved body 43d0 is located on the connecting member 43d near the support end of the push-pull body 43, and is inclined or bent outward toward the push-pull end of the frame body 41 relative to the extending direction of the connecting member 43d in the static state;

[0092] Among them, the push-pull body 43 further includes an anti-slip sleeve that wraps the support member 43b of the push-pull body 43.

[0093] The curved body 43d0 can be the end of the connecting member 43d, which is a part of the connecting member 43d and can be integrally formed with the connecting member 43d. As Figure 3As shown, from the side view of one side of the frame body 41, an obtuse angle is formed between the whole of the curved body 43d0 and the whole of the connecting member 43d. Specifically, in the static state, the curved body 43d0 can tilt forward towards the front of the push-pull end of the frame body 41 facing away from the frame body 41. Among them, the curved body 43d0 can also bend forward towards the front of the push-pull end, so that an obtuse angle is formed between the whole of the curved body 43d0 and the whole of the connecting member 43d. Thereby, the push-pull body 43 can achieve a stable self-locking state in the static state. In this self-locking state, the push-pull body 43 and the frame body 41 maintain stable abutment, and it is necessary to rely on external force to change the abutment. Moreover, a layer of anti-slip sleeve is wrapped outside the support member 43b connecting the curved body 43d0 and perpendicular to it, which can further strengthen the contact friction between the support member 43b and the plane where the original position is located in the static state, and improve the self-locking effect. In addition, a layer of anti-slip sleeve can also be included outside the push-pull member 43a to be more conducive to pushing, pulling, holding and grasping. Among them, the anti-slip sleeve can be a silicone sleeve or a silicone tube.

[0094] Therefore, with a very simple and extremely low-cost structural design, the push-pull body 43 can achieve stable static placement on the frame body 41 in the static state and stable push-pull effect in the push-pull state.

[0095] As Figure 3 and Figure 6 shown, according to an embodiment of the present disclosure, in the static state, the support member 43b of the push-pull body 43 contacts the plane where the push-pull storage structure is located, and at least one caster of the frame body 41 close to the push-pull end of the frame body 41 is in a suspended state.

[0096] In the static state, the frame body 41 of the push-pull storage structure 4 is in a static state. At this time, since the distance L2 between the support member 43b (i.e., the lower end of the curved body 43d0) and the lower surface of the main body of the frame body 41 is greater than the distance L1 between the front caster 41e on the frame body 41 and the lower surface of the main body of the frame body 41, the front caster 41e located below the push-pull end of the frame body 41 is in a suspended state. At the same time, due to the self-locking effect of the horizontal distance L3 between the support member 43b that the curved body 43d0 can support and the moving member 43c, it can further prevent the front caster 41e from easily falling due to the action of gravity and contacting the plane where the original position is located. At the same time, because the friction force received by the support member 43b is large, it can effectively prevent the frame body 41 from sliding abnormally. When it is necessary to pull the frame body 41, by pushing, pulling, holding or grasping the push-pull member 43a of the push-pull body 43, the push-pull body 43 is separated from the abutment with the end surface of the push-pull end of the frame body 41, so that the part of the push-pull body 43 below the moving member 43c abuts on the lower surface of the frame body 41. At this time, the front caster 41e no longer remains suspended and contacts the plane where the original position is located. The frame body 41 can then move along the track body 42 at any time due to the thrust or pull force received by the push-pull body 43.

[0097] As Figure 2 , Figure 7 , Figure 8 and Figure 11 shown, according to an embodiment of the present disclosure, the push-pull storage structure further includes a storage table 5.

[0098] The storage table 5 is disposed above the frame 41 corresponding to at least one fixing position 41a of the frame 41 for storing objects.

[0099] As Figure 1 - As Figure 8 shown, on the other hand, the present disclosure provides an incubator 2, which includes a box body 25, the above-mentioned push-pull storage structure 4, and a box door 21.

[0100] The box body 25 has an accommodation space;

[0101] The push-pull storage structure 4 is disposed in the accommodation space of the box body 25 and on the bottom surface of the accommodation space for placing cultures;

[0102] The box door 21 is matched with the box opening of the accommodation space of the box body 25 and is movably connected to the box body 25.

[0103] The accommodation space of the box body 25 can be equivalent to the storage space for placing the push-pull storage structure 4, and the bottom surface of the accommodation space can be equivalent to the plane where the original position is located.

[0104] One side of the incubator 2 is provided with a box door 21 that can be opened to expose the accommodation space. Among them, a latch 22 for locking it is provided on the box door 21, and a plurality of quick-locking handles 23 are distributed along the opening side of the accommodation space corresponding to the box door 21. By means of the handle 23, the incubator 2 can be quickly connected to the isolator 1 for aseptic operation. At the same time, a door lock 24 is also provided on the top of the box body 25 to prevent the box door 21 from being opened randomly. The above-mentioned push-pull storage structure 4 is placed inside the incubator 2, and the storage table 5 is placed on its frame 41.

[0105] As Figures 8 - 11 shown, on the other hand, the present disclosure provides a cell workstation, which includes the above-mentioned incubator 2, isolator 1, and mover 3.

[0106] The push-pull storage structure 4 in the incubator 2 is used for placing cultures;

[0107] The isolator 1 is connected to the incubator 2, and the connection port 13 of the isolator 1 provided on one side of the isolator 1 corresponds to the box door 21 of the incubator 2;

[0108] The mover 3 is arranged below the incubator 3 and is used to support the incubator 3 and connect it to the isolator 1.

[0109] The isolator 1 for aseptic operation is provided with an operation port 11 on the front, enabling the user to perform aseptic culture operations in the internal space of the isolator 1 through this operation port 11. An airtight silicone glove 12 is installed on the operation port 11, which can effectively prevent leakage points in the closed space of the isolator, maintain the aseptic operation effect, and also prevent the user from directly contacting the culture and causing personal safety risks (such as hand corrosion). In addition, the isolator 1 is provided with a connection port 13 on the side wall, and the connection port 13 can be hermetically connected to the incubator 2 corresponding to the door 21 of the incubator 2.

[0110] As Figure 7 、 Figure 10 and Figure 11 shown, according to an embodiment of the present disclosure, the isolator 1 includes an operating table.

[0111] The operating table is arranged in the operation space of the isolator 1 and is located on the bottom surface of the operation space; wherein, the tabletop of the operating table is provided with limit holes 14a that match the limit posts 42b on each track member 42e of the rail body 42 of the push-pull storage structure 4.

[0112] Among them, in the static state, the push-pull storage structure 4 is located in the accommodation space of the incubator 2. In the push-pull state, the door 21 of the incubator 2 is in the open state and is located in the operation space of the isolator 1. And through the matching of the limit posts 42b and the limit holes 14a, the starting end of the movement of the track member 42e of the rail body 42 of the push-pull storage structure 4 is arranged on the bottom surface in the accommodation space of the incubator 2, and its stopping end of the movement is arranged on the tabletop of the operating table in the operation space of the isolator 1.

[0113] Among them, an operating table is arranged inside the isolator 1, and the operating surface of the operating table can be provided with limit holes 14a as the plane 14 where the above-mentioned picking and placing position is located. The limit holes 14a are arranged in one-to-one correspondence and matching with the limit posts 42b of the rail body 42 of the above-mentioned push-pull storage structure 4. Through the cooperation of the two, when the rack body 41 moves along the rail body 42, the stability of the rail body 42 is maintained, so as to ensure the effective stability of the movement and facilitate the picking and placing of the culture products on the storage table 5 on the rack body 41.

[0114] Therefore, as Figure 11 shown, combining the above Figures 1 - 3 and Figures 5 - 7 shown content, the usage process of the above-mentioned cell workstation for the push-pull storage structure 4 during aseptic operation is listed as follows:

[0115] First, in the initial state, the push-pull storage structure 4 is located in the closed incubator 2, and the incubator 2 is hermetically docked with the isolator 1. At this time, the push-pull storage structure 4 is in a static state and stops on the bottom surface of the accommodation space of the incubator 2 which is the plane of the original position. The push-pull body 43 is in contact with the frame body 41, and the rail body 42 is hung on the frame body 41. Among them, the culture product is placed on the storage table 5 on the frame body 41 of the push-pull storage structure 4.

[0116] Secondly, when the user uses the isolator 1 and ensures a sealed and sterile environment, the user opens the door of the incubator 2 that is hermetically docked with the isolator 1 inside the isolator 1, so that the isolator 1 and the incubator 2 are connected.

[0117] After that, take down the rail body 42 hung on the frame body 41, and match the limit hole 14a provided on the tabletop of the operation table of the isolator 1 which is the plane of the pick-up and placement position 14, and cooperate the limit post 42b on the rail body 42 with it, so that the rail body 42 can be erected between the bottom surface of the incubator 2 and the tabletop of the operation table of the isolator 1.

[0118] Furthermore, hold the push-pull member 43a at the holding part of the push-pull body 43 and apply force obliquely downward and forward, so that the push-pull body 43 rotates, and the whole is parallel to the upper and lower surfaces of the frame body 41, so that the entire push-pull storage structure is in a push-pull state.

[0119] Then, hold the push-pull member 43a and apply a pulling force in front of the push-pull end of the frame body 41, so that the front caster of the frame body 41 contacts the limit slope 42c of the rail body 42 and rotates along the track of the rail body 42. Thus, the frame body 41 is pulled to move towards the inside of the isolator 1 until the rear caster of the frame body 41 is limited by the limit slope 42c. At this time, the front caster 41e of the frame body 41 enters the isolator 1 and contacts the tabletop of the operation table. At this time, it is very convenient for the user to take the culture product stored on the storage table 5 of the push-pull storage structure 4.

[0120] Similarly, those skilled in the art should understand that after use, only the reverse operation according to the above operation steps is required to push the push-pull storage structure 4 back to the initial state, which will not be elaborated here.

[0121] Therefore, the above-mentioned cell workstation of the present disclosure can be applied to an incubator with a relatively large volume, and at the same time, it can very conveniently pull out the internal culture product together with the built-in push-pull storage structure frame body, effectively solving the problem that due to the limited length of the human arm, it is impossible to stably take the culture product outside the arm length range. Moreover, the structural design of its push-pull storage structure is simple and effective, the processing cost is relatively low, and the requirement for processing accuracy is also relatively low, which is very suitable for large-scale industrial application.

[0122] So far, the embodiments of the present disclosure have been described in detail with reference to the accompanying drawings.

[0123] The specific embodiments described above further elaborate on the objectives, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
