Description

Technical Field

[0001] The invention relates to the field of microbial culture, in particular to a microbial cell culture device. Background Art

[0002] Microbial culture is a kind of equipment specially used in medical, biological and chemical experiments. In the medical field, stem cells can be cultured through microbial culture to provide them with a suitable growth environment.

[0003] The existing microbial cell culture equipment can specifically refer to the Chinese invention patent with application number: CN202010788850.8, an orbital microbial culture, which includes an incubator body defining a culture chamber and an orbital oscillator configured as an oscillation tray. The orbital oscillator includes a drive motor, which includes a stator and a rotor and an eccentric bearing mounted to the rotor. The orbital oscillator is fixed in the culture chamber or in a movable form, without being fixed, but only placed inside the culture chamber. The orbital oscillator also includes a bearing, which is configured to support the rotor on a support device. The rotor, bearing and support device are configured to seal and isolate the stator from the culture chamber.

[0004] However, in the process of taking out the culture container inside the microbial cell culture device in the prior art, it is necessary to open the box door first, and then release the fixation of the culture container by the oscillation platform, and finally take out the culture container. Due to the limited internal space of the microbial culture, the range of hand movement will be limited when taking out, which is not convenient for operation and is easy to accidentally touch other culture containers. In addition, multiple groups of culture containers are often fixed on the oscillation platform at one time, so when taking them out, it is necessary to release the fixation of the culture container by the oscillation platform one by one, which will take a long time and make the whole taking out process more inconvenient. Therefore, a microbial cell culture device is proposed to address the above problems. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the present invention provides a microbial cell culture device.

During the sliding out of the mobile platform, the mobile buckle will be gradually separated from the fixed buckle through the structural design of the fixing mechanism, so as to facilitate the removal of the culture container fixed on the mobile platform. This solves the problem that in the process of taking out the culture container inside the microbial cell culture equipment in the prior art, the box door needs to be opened first, and then the fixation of the culture container by the oscillating platform needs to be released before the culture container can be taken out. Due to the limited internal space of the microbial culture, the range of hand movement will be subject to certain restrictions when taking out, which is not convenient for operation and is easy to accidentally touch other culture containers. In addition, multiple groups of culture containers are often fixed on the oscillating platform at a time, so that when taking them out, it is necessary to release the fixation of the oscillating platform on the culture container one by one, which will take a long time and make the entire removal process more inconvenient.

[0007] Preferably, the fixing mechanism comprises a rectangular groove, the rectangular groove is opened at the bottom end of the moving platform, the top of the inner wall of the rectangular groove is opened with a through groove, the inside of the through groove is slidably connected with a long rod, the top of the long rod is fixedly connected to the moving rod, the top of the moving rod is fixedly connected to the two sets of moving plates, the moving plate is fixedly connected with a protrusion, the protrusion is fixedly connected to the bottom end of the moving buckle, the bottom end of the long rod is fixedly connected with an abutment block, one side of the abutment block abuts with the guide rail, the guide rail is fixedly connected to the oscillation platform, and the left and right sides of the moving rod are fixedly connected with the first spring. Through the structural design of the fixing mechanism, when the moving platform is pulled out, the moving rod will move in the direction away from the fixed buckle, thereby driving the moving buckle fixed on the moving plate to separate from the fixed buckle, which solves the problem that when the moving platform is pulled out, the mobile platform needs to be released from the fixation of the culture container in turn before the culture container can be removed, so as to facilitate the culture container to be taken out.

[0008] Preferably, the side of the first spring away from the moving rod is fixedly connected to the inner wall of the long slot, the long slot is opened on the groove, the long slot is connected to the through slot, and the groove is opened at the top of the moving platform.

Through the two groups of first springs, sufficient thrust is ensured to push the moving rod to move.

[0009] Preferably, the top end of the movable plate contacts the bottom end of the fixed plate, and the fixed plate is fixedly connected to the inner wall of the groove. Three groups of notches are provided on the side of the fixed plate close to the movable buckle, and the inner wall of the notch contacts the protrusion. The protrusion fixed on the movable plate is accommodated by the three groups of notches on the fixed plate, so that the movable plate can be completely overlapped under the fixed plate. The fixed plate is fixed on the inner wall of the groove, and when the movable buckle is separated from the fixed buckle, the fixed plate can provide support for the bottom end of the culture container.

[0010] Preferably, the fixed plate is provided with an ejection mechanism, the ejection mechanism includes a second magnet, the front and rear sides of the second magnet are fixedly connected to a limiting block, the limiting block is slidably connected to the inside of the limiting groove, the inner wall of the fixed groove is opened, and three groups of first magnets are inlaid on the top of the movable plate, the magnetic poles of the first magnet and the second magnet are opposite, through the structural design of the ejection mechanism, in the process of the movable buckle and the fixed buckle gradually separating and opening, the movable plate will slide out from the bottom end of the fixed plate, and when sliding out a certain distance, the first magnet inlaid on the movable plate will lift up the second magnet, so that the block can no longer drive the culture container to move, thereby solving the problem that the movable buckle will drive the culture container to move continuously.

[0011] Preferably, a card block is rotatably connected inside the movable buckle, a torsion spring is sleeved on the bottom end of the card block, four groups of the card blocks are provided, and a rubber sheet is fixedly connected to the card block. Through the card block rotatably connected inside the movable buckle, when the movable buckle is separated from the fixed buckle, when the card block is no longer inserted inside the fixed buckle, the card block will contact the surface of the culture container, thereby bringing the culture container out, solving the problem that the culture container will still contact the inner wall of the fixed buckle when the movable buckle is separated from the fixed buckle.

[0012] Preferably, the card block is inserted into the interior of the fixed buckle, one side of the fixed buckle is in contact with the movable buckle, the rubber sheet abuts against the inner wall of the fixed buckle, and the card block is provided with an inclined surface. The abutment between the rubber sheet and the inner wall of the fixed buckle is used to buffer the space between the card block and the inner wall of the fixed buckle, and the inclined surface on the card block facilitates the card block to be inserted into the interior of the fixed buckle again.

[0013] Preferably, the left and right sides of the box door are slidably connected to the inside of the U-shaped groove, the U-shaped groove is opened on the inner wall of the movable groove, and the movable groove is opened on the rear end of the box door.

[0015] Preferably, the top end of the second spring is fixedly connected to the inner wall of the cavity, and the top end of the third connecting rod is inserted in the middle of the cavity. The third connecting rod is connected to the third connecting rod by the second spring so that the third connecting rod will not slide to the lowest end inside the cavity, and the top end of the third connecting rod is located in the middle of the cavity, so that the third connecting rod has a movable distance upward or downward.

[0016] The present invention is beneficial in that:

[0017] 1. The microbial cell culture device described in the present invention has a structural design of a sliding mechanism. When the box door is pulled to open the incubator body, the first connecting rod, the second connecting rod and the connecting assembly at the rear end of the box door can bring out the moving platform on the oscillating platform, so that when taking out the culture container, there is no need to operate inside the microbial culture. This solves the problem that in the process of taking out the culture container inside the microbial cell culture device in the prior art, the box door needs to be opened first, and then the fixing of the culture container by the oscillating platform needs to be released before the culture container can be taken out. Due to the limited space inside the microbial culture, the range of hand movement will be subject to certain restrictions when taking out, which is not convenient for operation and is easy to accidentally touch other culture containers.

[0018] 2. The microbial cell culture device described in the present invention has a structural design of a fixing mechanism. When the mobile platform is pulled out, the moving rod will move in a direction away from the fixing buckle, thereby driving the moving buckle fixed on the moving plate to separate from the fixing buckle, so that when the mobile platform is pulled out, the fixing of the oscillating platform to the culture container can be released, which solves the problem that multiple groups of culture containers are often fixed on the oscillating platform at one time, so that when removing the oscillating platform, it is necessary to release the fixing of the oscillating platform to the culture container one by one, which will take a long time and make the whole removal process inconvenient;

[0019] 3. The microbial cell culture device described in the present invention uses a card block that is rotatably connected inside a movable buckle. When the movable buckle is separated from the fixed buckle and the card block is no longer inserted inside the fixed buckle, the card block will contact the surface of the culture container, and the culture container will be brought out through contact friction to separate it from the fixed buckle, thereby solving the problem that when the movable buckle and the fixed buckle are separated, one side of the culture container will still contact the inner wall of the fixed buckle, resulting in the need to manually push the culture container for a distance before the culture container can be removed;

[0020] 4. The microbial cell culture device described in the present invention has a structural design of the ejection mechanism. In the process of the mobile buckle and the fixed buckle being gradually separated and opened, the mobile plate will slide out from the bottom end of the fixed plate. When sliding out a certain distance, the first magnet embedded in the mobile plate will lift up the second magnet, so that the block cannot continue to drive the culture container to move, thereby solving the problem that the mobile buckle will drive the culture container to move, so that the culture container will still fit with the inner wall of one side of the mobile buckle.

[0021] 5. The microbial cell culture equipment described in the present invention has a structural design of the connecting assembly. In the process of the oscillating platform driving the mobile platform to oscillate, the third connecting rod and the housing can rotate left and right on the fourth connecting rod, thereby ensuring that the oscillation of the mobile platform in the horizontal direction is not affected, and the third connecting rod can also slide inside the cavity to change the overall length of the connecting assembly, so that when the mobile platform oscillates in the front and rear directions, it will not be unable to move due to the limitation of the first connecting rod and the movable groove.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 - Fig.14As shown, a microbial cell culture device comprises an incubator body 1; an oscillating platform 21 is arranged inside the incubator body 1, a box door 20 is rotatably connected to the front end of the incubator body 1, a sliding mechanism is arranged on the rear end of the box door 20, the sliding mechanism comprises two groups of first connecting rods 22, a connecting assembly is rotatably connected to the bottom end of the first connecting rod 22, a second connecting rod 26 is rotatably connected to the bottom end of the connecting assembly, a pulley 27 is fixedly connected to the side of the second connecting rod 26 close to a moving platform 29, the pulley 27 is slidably connected to the inside of a slide groove 28, the slide groove 28 is opened on the left and right sides of the moving platform 29, three groups of trapezoidal blocks 30 are fixedly connected to the bottom end of the moving platform 29, the trapezoidal blocks 30 are slidably connected to the inside of a trapezoidal groove 31, the trapezoidal groove 31 is opened on the top of the moving platform 29, two groups of fixing mechanisms are arranged inside the moving platform 29, one group of fixing mechanisms comprises six groups of moving buckles 60 and fixed buckles 66, and the two groups of fixing mechanisms are mirror-distributed along the central axis of the moving platform 29;

[0040] During operation, when taking out the culture container inside the microbial cell culture device in the prior art, the door needs to be opened first, and then the fixation of the culture container on the oscillating platform needs to be released, and finally the culture container can be taken out. Due to the limited space inside the microbial culture, the range of hand movement will be limited when taking it out, which is not convenient for operation and is easy to accidentally touch other culture containers. Through the structural design of the sliding mechanism, when the door 20 is pulled to open the incubator body, the first connecting rod 22, the second connecting rod 26 and the connecting assembly at the rear end of the door 20 can bring out the movable platform 29 on the oscillating platform 21, so that there is no need to operate inside the microbial culture when taking out the culture container. When the culture container inside the incubator body 1 is to be taken out, it is only necessary to pull up the door 20 first. When the door 20 is pulled up, the first connecting rod 22 will be inside the movable groove 25. The first connecting rod 22 pulls the second connecting rod 26 through the connecting assembly, so that the pulley 27 fixed on the second connecting rod 26 slides in the slide groove 28. When the pulley 27 abuts against the inner wall of the front end of the slide groove 28, the box door 20 is continued to be pulled, and the movable platform 29 will be pulled out. The three groups of trapezoidal blocks 30 fixed on the bottom end of the movable platform 29 will slide in the trapezoidal groove 31 and finally be brought to the outside of the incubator body 1, so that the staff can take the culture container outside the incubator body 1. The pulley 27 can reduce the friction between it and the inner wall of the slide groove 28, so that the movement of the pulley 27 is smoother. A set of fixing mechanisms includes six groups of movable buckles 60 and fixed buckles 66, so that 12 groups of culture containers can be fixed on the movable platform 29 at the same time, and the two groups of fixing mechanisms are distributed in a mirror image. The two groups of fixing mechanisms are used to separate the movable buckles 60 and the fixed buckles 66.

[0041] Further, the fixing mechanism includes a rectangular groove 40, which is provided at the bottom end of the moving platform 29, a through groove 41 is provided on the top of the inner wall of the rectangular groove 40, a long rod 42 is slidably connected inside the through groove 41, the top end of the long rod 42 is fixedly connected to the moving rod 45, the top end of the moving rod 45 is fixedly connected to two groups of moving plates 49, a protrusion 51 is fixedly connected to the moving plate 49, the protrusion 51 is fixedly connected to the bottom end of the moving buckle 60, the bottom end of the long rod 42 is fixedly connected to an abutment block 43, one side of the abutment block 43 abuts against a guide rail 44, the guide rail 44 is fixedly connected to the oscillation platform 21, and the left and right sides of the moving rod 45 are fixedly connected to the first spring 46;

[0042] During operation, through the structural design of the fixing mechanism, when the movable platform 29 is pulled out, the movable rod 45 will move in the direction away from the fixing buckle 66, thereby driving the movable buckle 60 fixed on the movable plate 49 to separate from the fixing buckle 66, so that when the movable platform 29 is pulled out, the fixation of the oscillating platform 21 to the culture container can also be released, which solves the problem that multiple groups of culture containers are often fixed on the oscillating platform 21 at one time, so that when removing the culture containers, it is necessary to release the fixation of the oscillating platform 21 to the culture containers one by one, which will take a long time and make the whole removal process inconvenient. When the box door 20 is not opened, the abutment between the guide rail 44 and the abutment block 43 makes the long rod 42 close to the inner side of one side of the through groove 41 The wall makes the moving rod 45 unable to move, and makes the moving buckle 60 contact with the fixed buckle 66, so as to fix the culture container. In the process of the moving platform 29 continuously sliding forward, due to the gradual decrease in the distance between the two guide rails 44, the long rod 42 will move inside the through groove 41 under the push of the first spring 46, and the moving rod 45 will also move in the long groove 47. Since the top of the moving rod 45 is fixedly connected with the two groups of moving plates 49, the movement of the moving rod 45 will make the moving plate 49 and the moving buckle 60 fixed on the moving plate 49 move on the groove 48, and then gradually separate the moving buckle 60 from the fixed buckle 66, so as to achieve the effect of releasing the fixation of the culture container.

[0043] Furthermore, the first spring 46 is fixedly connected to the inner wall of the long slot 47 at one side away from the moving rod 45, the long slot 47 is provided on the groove 48, the long slot 47 is communicated with the through slot 41, the groove 48 is provided at the top of the moving platform 29, the first spring 46 fixedly connected to one side of the moving rod 45 is in a compressed state, and the first spring 46 fixedly connected to the other side of the moving rod 45 is in a stretched state;

[0044] During operation, the through slot 41 and the long slot 47 provide space for the movement of the long rod 42 and the mobile rod 45 respectively, and the two groups of first springs 46 are in tension and compression states respectively, which makes the two groups of first springs 46 have a pulling force pointing to one side of the mobile rod 45, so as to continuously push the mobile rod 45 to move in the process of the mobile platform 29 gradually sliding out, so that the mobile buckle 60 can be separated from the fixed buckle 66, and the top end of the long slot 47 is opened on the groove 48, but the bottom end of the long slot 47 is connected.

[0045] Furthermore, the top of the movable plate 49 contacts the bottom of the fixed plate 50, and the fixed plate 50 is fixedly connected to the inner wall of the groove 48. Three groups of notches 52 are formed on one side of the fixed plate 50 close to the movable buckle 60, and the inner wall of the notch 52 contacts the protrusion 51.

[0046] During operation, the movable plate 49 is located on the bottom end of the fixed plate 50. When the movable rod 45 moves inside the long groove 47, the movable plate 49 will slide on the groove 48, and the fixed plate 50 is fixed on the groove 48, so that when the movable buckle 60 is separated from the fixed buckle 66, the fixed plate 50 can still provide support for the bottom end of the culture container, and the three groups of notches 52 on the fixed plate 50 are the same size as the protrusions 51, so that the movable plate 49 can be completely overlapped on the bottom end of the fixed plate 50 to avoid occupying unnecessary space.

[0047] Furthermore, the fixed plate 50 is provided with an ejection mechanism, which includes a second magnet 54, and the second magnet 54 is fixedly connected to a limiting block 57 on both the front and rear sides. The limiting block 57 is slidably connected to the inside of the limiting groove 56 and is provided on the inner wall of the fixed groove 55. Three groups of first magnets 53 are inlaid on the top of the movable plate 49, and the magnetic poles of the first magnet 53 and the second magnet 54 are the same;

[0048] During operation, through the structural design of the ejection mechanism, in the process of the movable buckle 60 and the fixed buckle 66 gradually separating and opening, the movable plate 49 will slide out from the bottom end of the fixed plate 50, and when sliding out a certain distance, the first magnet 53 embedded in the movable plate 49 will lift up the second magnet 54, and the lifted up second magnet 54 will block the bottom end of the culture container, so that the block 63 cannot continue to drive the culture container to move, thereby solving the problem that the movable buckle 60 will drive the culture container to move all the time, and when the second magnet 54 is lifted up, the ejection distance of the second magnet 54 is limited by the limit blocks 57 on both sides of the second magnet 54 and the limit grooves 56 opened on the inner wall of the fixed groove 55, so as to prevent the second magnet 54 from separating from the fixed groove 55, and ensure that the second magnet 54 can only move inside the fixed groove 55.

[0049] Furthermore, a clamping block 63 is rotatably connected inside the movable buckle 60, a torsion spring 62 is sleeved on the bottom end of the clamping block 63, four groups of clamping blocks 63 are provided, and a rubber sheet 64 is fixedly connected to the clamping block 63;

[0050] During operation, by rotating the connected block 63 inside the mobile buckle 60, when the mobile buckle 60 is separated from the fixed buckle 66, when the block 63 is no longer inserted into the fixed buckle 66, the block 63 will contact the surface of the culture container, thereby bringing the culture container out, solving the problem that the culture container still contacts the inner wall of the fixed buckle 66 when the mobile buckle 60 is separated from the fixed buckle 66, and the four groups of blocks 63 and the rubber sheets 64 glued and fixed on the blocks 63 can provide sufficient friction between the blocks 63 and the surface of the culture container.

[0051] Furthermore, the block 63 is inserted into the interior of the fixed buckle 66, one side of the fixed buckle 66 contacts the movable buckle 60, the rubber sheet 64 abuts against the inner wall of the fixed buckle 66, and an inclined surface is provided on the block 63;

[0052] During operation, when the movable buckle 60 contacts the fixed buckle 66, the block 63 on the movable buckle 60 will be inserted into the interior of the fixed buckle 66. Only when they are separated will the block 63 come into contact with the surface of the culture container and carry it out a certain distance. Through the abutment between the rubber sheet 64 and the inner wall of the fixed buckle 66, when the block 63 is inserted into the interior of the fixed buckle 66, the rubber sheet 64 can buffer the space between the block 63 and the inner wall of the fixed buckle 66, and the inclined surface on the block 63 facilitates the insertion of the block 63 into the interior of the fixed buckle 66 again.

[0053] Further, the left and right sides of the box door 20 are slidably connected to the inside of the U-shaped groove 24, the U-shaped groove 24 is opened on the inner wall of the movable groove 25, and the movable groove 25 is opened on the rear end of the box door 20;

[0054] During operation, the first connecting rod 22 is arranged inside the movable groove 25 so that when the door 20 is not pulled, the first connecting rod 22 can be received inside the movable groove 25 and the moving distance of the first connecting rod 22 is limited by the U-shaped groove 24 opened on the inner wall of the movable groove 25.

[0055] Further, the connecting assembly includes a fourth connecting rod 74, the fourth connecting rod 74 is rotatably connected to the bottom end of the first connecting rod 22, a casing 71 is rotatably connected to the bottom end of the fourth connecting rod 74, a cavity 72 is provided inside the casing 71, a third connecting rod 70 is slidably connected inside the cavity 72, the bottom end of the third connecting rod 70 is rotatably connected to the second connecting rod 26, and a second spring 73 is fixedly connected to the top end of the third connecting rod 70;

[0056] During operation, through the structural design of the connecting assembly, in the process of the oscillation platform 21 driving the mobile platform 29 to oscillate, the third connecting rod 70 and the sleeve shell 71 can rotate left and right on the fourth connecting rod 74, thereby ensuring that the oscillation of the mobile platform 29 in the horizontal direction is not affected, and the third connecting rod 70 can also slide inside the cavity 72 to change the overall length of the connecting assembly, so that when the mobile platform 29 oscillates in the front and rear directions, it will not be unable to move due to the restrictions of the first connecting rod 22 and the movable groove 25.

[0057] Furthermore, the top end of the second spring 73 is fixedly connected to the inner wall of the cavity 72, and the top end of the third connecting rod 70 is inserted into the middle of the cavity 72;

[0058] During operation, the third connecting rod 70 is connected to the third connecting rod 70 by the second spring 73 so that the third connecting rod 70 will not slide to the lowest end inside the cavity 72, and the top end of the third connecting rod 70 is located in the middle of the cavity 72, so that the third connecting rod 70 has a movable distance upward or downward.

[0059] Working principle: In the process of taking out the culture container inside the microbial cell culture equipment in the prior art, it is necessary to open the box door first, and then release the fixation of the culture container on the oscillation platform, and finally take out the culture container. Due to the limited internal space of the microbial culture, the range of hand movement will be limited when taking it out, which is not convenient for operation and it is easy to accidentally touch other culture containers. Through the structural design of the sliding mechanism, when the box door 20 is pulled to open the incubator body, the first connecting rod 22, the second connecting rod 26 and the connecting assembly at the rear end of the box door 20 can bring out the movable platform 29 on the oscillation platform 21, so that there is no need to operate inside the microbial culture when taking out the culture container. When the culture container inside the incubator body 1 is to be taken out, it is only necessary to pull up the box door 20 first. When the box door 20 is pulled up, the first connecting rod 22 will be in the movable groove 25 The first connecting rod 22 pulls the second connecting rod 26 through the connecting assembly, so that the pulley 27 fixed on the second connecting rod 26 slides in the slide groove 28. When the pulley 27 abuts against the inner wall of the front end of the slide groove 28, the box door 20 is continued to be pulled, and the movable platform 29 will be pulled out. The three groups of trapezoidal blocks 30 fixed on the bottom end of the movable platform 29 will slide in the trapezoidal groove 31 and finally be brought to the outside of the incubator body 1, so that the staff can take the culture container outside the incubator body 1. The pulley 27 can reduce the friction between it and the inner wall of the slide groove 28, so that the movement of the pulley 27 is smoother. A set of fixing mechanisms includes six groups of movable buckles 60 and fixed buckles 66, so that 12 groups of culture containers can be fixed on the movable platform 29 at the same time, and the two groups of fixing mechanisms are distributed in a mirror image, and the two groups of fixing mechanisms are used to separate the movable buckle 60 and the fixed buckle 66.
