Description

Technical Field

[0001] The invention relates to the technical field of artificial climate chamber equipment, in particular to a movable lifting platform for an artificial climate chamber. Background Art

[0002] The artificial climate chamber is a special constant temperature and light culture device for the culture of bacteria, molds and other microorganisms and seed germination tests. It simulates the natural climate for experiments. Culture dishes are placed on the partitions in the artificial climate chamber. The culture dishes are generally small culture bottles or large culture pots. When placing or taking out the culture dishes, the operator needs to go back and forth between the artificial climate chamber and the test bench, which is time-consuming and laborious.

[0003] In order to solve the above problems, the prior art discloses a movable lifting platform for an artificial climate chamber, comprising a base, a column, a connecting rod and a lifting mechanism, wherein the upper part of the base is connected to a fixed plate through a column, and a lifting mechanism is arranged in the middle of the column; the lifting mechanism comprises a lifting platform, a first screw, a second screw, a connecting platform and a rotating handle, wherein the first screw is arranged between the fixed plate and the base, and the lifting platform is connected to the first screw through a connecting platform at the side; the first screw is connected to the second screw through a bevel gear set, and a tray is arranged on the upper part of the lifting platform;

[0004] Although this patent solves the problem of operators having to spend a lot of time and effort to go back and forth between the artificial climate chamber and the test bench to take and place culture dishes, it still has the following defects: if the culture dishes on the partition inside the artificial climate chamber are multiple small culture bottles, the operator needs to take out the culture bottles from the artificial climate chamber and put them on the tray many times; if the culture dishes on the partition inside the artificial climate chamber are large culture pots, it is not easy to take the culture pots out of the artificial climate chamber and place them on the tray because the culture pots and the soil inside are heavy, which affects the convenience of taking out the culture dishes from the artificial climate chamber. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a movable lifting platform for an artificial climate box, which is convenient for taking out multiple culture bottles arranged side by side from the artificial climate box at one time, and is also convenient for taking out heavier culture pots from the artificial climate box. It has good adaptability to culture dishes and is convenient and quick to operate. The taken out culture bottles or culture pots are placed on the adaptation table of the climate box. With the movement of the width-adjustable movable base, they can move back and forth between the artificial climate box and the test bench. When used in conjunction with the artificial climate box, it saves time and effort to transfer the culture dishes in the artificial climate box, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a movable lifting platform for an artificial climate chamber, comprising a width-adjustable movable base, the width-adjustable movable base comprising a transverse sleeve, a transverse sliding rod, a longitudinal beam, a universal wheel, a convex block and a synchronous transverse shifting assembly, the left and right ends of the transverse sleeve are respectively slidably connected to one end of two transverse sliding rods, the other ends of the two transverse sliding rods are respectively fixedly connected to two longitudinal beams, universal wheels are respectively installed on the lower sides of the two ends of each longitudinal beam, a convex block is fixedly connected to the rear side of the middle part of the transverse sleeve, a synchronous transverse shifting assembly is installed on the convex block, the synchronous transverse shifting assembly is connected to the two transverse sliding rods, and further comprising:

[0007] The climate box adapter lifting mechanism comprises a vertical rod, a climate box adapter plate, a sliding sleeve, an oblique blade and a lifting control assembly, wherein two vertical rods are fixedly connected to the horizontal sleeve, two sliding sleeves are fixedly connected to the front end of the climate box adapter plate, an oblique blade is connected to the rear end of the climate box adapter plate, two sliding sleeves are respectively slidably connected to the two vertical rods, and the climate box adapter plate is connected to the protrusion through the lifting control assembly;

[0008] The culture box scooping and dragging mechanism is installed in the middle of the climate chamber adapter plate.

[0009] The transverse sleeve, transverse slide bar and longitudinal beam form an I-shaped base. The universal wheel facilitates the movement of the I-shaped base, and is convenient for moving back and forth between the artificial climate box and the test bench. In order to fix the I-shaped base after moving, a wheel brake is installed on the universal wheel. The opposite synchronous transverse movement assembly can drive the transverse slide bar to move transversely relative to the transverse sleeve, which can change the distance between the two longitudinal beams. If the distance between the two longitudinal beams becomes larger, the I-shaped base will be more stable and will not be easily affected by the top structure and tip over. If the distance between the two longitudinal beams becomes smaller, it is suitable for activities in a narrow space. At the same time, the change in the distance between the two longitudinal beams can also make the climate box adaptation plate closer to the artificial climate box or test bench, avoiding the climate box adaptation plate from being unable to get close to the artificial climate box or test bench due to the two longitudinal beams hitting the bottom of the artificial climate box or test bench too early. For example, when the distance between the two longitudinal beams increases and the I-shaped base is close to the artificial climate box, the artificial climate box If the hopper can be positioned between the two longitudinal beams, the rear end of the climate box adapter plate can be completely close to the front opening of the artificial climate box. The lifting control component is used to drive the climate box adapter plate to move up and down, so that the top of the climate box adapter plate is close to the partition in the artificial climate box. The sliding sleeve and the vertical rod are slidably connected so that the climate box adapter plate can move up and down stably. The setting of the inclined blade is conducive to the culture dish sliding along the inclined surface of the inclined blade to the upper side of the climate box adapter plate. The culture box scooping and dragging mechanism moves backward relative to the climate box adapter plate. The culture box scooping and dragging mechanism can scoop up the culture dish from the bottom of the artificial climate box, and then the culture box scooping and dragging mechanism moves forward relative to the climate box adapter plate to drag the scooped culture dish forward to the upper side of the climate box adapter plate. Since there is no limit on the four sides of the culture dish, this culture dish removal structure is suitable for heavier and larger culture boxes, but not for small culture bottles, because small culture bottles are easy to tip over when being scooped up.

[0010] Furthermore, the climate box adaptation lifting mechanism further includes a reinforcing rod and a top beam, the bottoms of the two vertical rods are connected by the reinforcing rod, and the tops of the two vertical rods are respectively connected to the two ends of the top beam.

The foot-operated air pump is installed in the middle of the front side of the horizontal sleeve through a bracket, and the middle part of the control air pipe is connected to the air release valve through an air release pipe, and the air release valve is installed on the reinforcement rod. The operator steps on the foot-operated air pump and uses it to pump air into the inflation pipe. The gas enters the lifting cylinder in one direction through the one-way valve and the control air pipe, which can extend the lifting cylinder, thereby pushing the climate box adapter plate to move up, open the air release valve, and the gas in the lifting cylinder is used through the control air pipe and the air release pipe. The lifting cylinder is shortened, which can allow the climate box adapter plate to move down, thereby realizing the lifting and lowering control of the climate box adapter plate.

[0012] Furthermore, the culture box scooping and dragging mechanism includes a longitudinal through groove, a U-shaped push-pull rod, a shovel plate and a blade strip.

[0015] Furthermore, it also includes a longitudinal movement mechanism, a height adjustment mechanism and a multi-culture bottle clamping mechanism. The left and right sides of the top of the climate box adaptation platform are respectively connected to the two ends of the longitudinal movement mechanism, and the top of the longitudinal movement mechanism is connected to the front end of the multi-culture bottle clamping mechanism through the height adjustment mechanism.

[0019] Compared with the prior art, the movable lifting platform used in the artificial climate box has the following beneficial effects:

[0020] 1. With the help of the longitudinal movement mechanism, height adjustment mechanism and multi-culture bottle clamping mechanism, it is convenient to take out multiple culture bottles side by side from the artificial climate box at one time, the transfer efficiency of the culture bottles is high, and the transfer of the culture bottles is convenient and fast.

[0021] 2. First, align the bottom of the climate chamber adapter plate with the top of the partition through the lifting control assembly, and then push the shovel plate backwards through the U-shaped push-pull rod to allow the shovel plate to move backwards in the longitudinal groove, and insert the shovel plate between the partition and the culture basin. The blade bar makes it easier for the shovel plate to be inserted into the bottom of the culture basin.

At this time, the top edge of the front side of the blade bar is against the bottom rear side of the culture basin, and the culture basin moves forward with the shovel plate. Because the top edge of the front side of the blade bar limits the bottom rear side of the culture basin, the culture basin is smoothly pushed forward to the upper side of the climate chamber adapter plate, and the heavier culture basin is smoothly transferred from the partition in the artificial climate chamber to the climate chamber adapter plate, which is convenient and quick to transfer the culture basin, saving time and effort.

[0022] 3. It has good adaptability to the culture dishes in the artificial climate box, and the operation is convenient and quick. The culture bottles or culture pots taken out are placed on the adaptation table of the climate box. With the movement of the width-adjustable mobile base, it can go back and forth between the artificial climate box and the test bench. It is used in conjunction with the artificial climate box to save time and effort in transferring the culture dishes in the artificial climate box. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] 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.

[0037] For example, see Figures 1 to 12 , this embodiment provides a technical solution: a movable lifting platform for an artificial climate chamber, comprising a width-adjustable movable base 1, the width-adjustable movable base 1 comprising a transverse sleeve 11, a transverse sliding rod 12, a longitudinal beam 13, a universal wheel 14, a protrusion 15 and a synchronous transverse shifting assembly, the left and right ends of the transverse sleeve 11 are respectively slidably connected to one end of two transverse sliding rods 12, the other ends of the two transverse sliding rods 12 are respectively fixedly connected to two longitudinal beams 13, the lower sides of both ends of each longitudinal beam 13 are respectively installed with universal wheels 14, the rear side of the middle of the transverse sleeve 11 is fixedly connected with a protrusion 15, the protrusion 15 is installed with a synchronous transverse shifting assembly, and the synchronous transverse shifting assembly is connected to the two transverse sliding rods 12;

[0038] The opposite synchronous transverse movement assembly includes a transverse movement slot 16, a connecting rod 17, a transverse movement screw nut 18, a transverse movement screw 19, and a knob 110. The middle part of the protrusion 15 is rotatably connected to the middle part of the transverse bidirectional screw. The bidirectional screw is connected by two transverse movement screws 19, and the threads on the two transverse movement screws 19 are in opposite directions. Two transverse movement slots 16 are respectively provided at the left and right ends of the rear side of the transverse sleeve 11. Two connecting rods 17 are respectively fixedly connected to the rear sides of the ends of the two transverse sliding rods 12 that are close to each other. The rear ends of the two connecting rods 17 pass through the corresponding transverse movement slots 11. 6 and are fixedly connected with two transverse screw nuts 18, which are respectively connected with two transverse screws 19, and the ends of the two transverse screws 19 away from the protrusion 15 are respectively fixedly connected with knobs 110. By means of the knob 110, the bidirectional screw is rotated clockwise, and the bidirectional screw cooperates with the two transverse screw nuts 18. With the help of the screw nuts, the two transverse slide rods 12 are driven to approach each other in the transverse sleeve 11. By means of the knob 110, the bidirectional screw is rotated counterclockwise, and the two transverse slide rods 12 are driven to move away from each other in the transverse sleeve 11.

[0039] It also includes a climate box adaptation lifting mechanism 2 and a culture box scooping and dragging mechanism 8;

[0040] The climate box adaptation lifting mechanism 2 includes a vertical rod 21, a climate box adaptation platform 26, a sliding sleeve 27, an oblique blade 215 and a lifting control component. Two vertical rods 21 are fixedly connected to the horizontal sleeve 11, and two sliding sleeves 27 are fixedly connected to the front end of the climate box adaptation platform 26. The rear end of the climate box adaptation platform 26 is integrally formed and connected with an oblique blade 215. The two sliding sleeves 27 are respectively slidably connected to the two vertical rods 21, and the climate box adaptation platform 26 is connected to the protrusion 15 through the lifting control component.

[0041] The climate box adaptation lifting mechanism 2 also includes a reinforcing rod 22 and a top beam 23. The bottoms of the two vertical rods 21 are connected by the reinforcing rod 22, and the tops of the two vertical rods 21 are respectively connected to the two ends of the top beam 23. The reinforcing rod 22 and the top beam 23 connect and fix the two vertical rods 21, making the two vertical rods 21 more stable.

[0042] The climate box adapter lifting mechanism 2 further includes a handle 24. Two handles 24 are respectively provided at both ends of the reinforcement rod 22. The handles 24 facilitate the movement of the width-adjustable movable base 1.

[0043] The lifting control assembly includes a lifting cylinder 25, a bracket 28, a foot-operated air pump 29, a control air pipe 210, a one-way valve 211, an inflation pipe 212, an air release pipe 213 and an air release valve 214. A vertical lifting cylinder 25 is installed on the top of the protrusion 15. The top of the lifting cylinder 25 is connected to the bottom of the climate box adapter plate 26. A control air pipe 210 is provided at the bottom of the lifting cylinder 25. The end of the control air pipe 210 is connected to one end of the inflation pipe 212 through a one-way valve 211, and the other end of the inflation pipe 212 is connected to the air outlet of the foot-operated air pump 29. The foot-operated air pump 29 is installed in the middle of the front side of the horizontal sleeve 11 through the bracket 28. The middle part of the control air pipe 210 is connected to the air release valve 214 through the air release pipe 213, and the air release valve 214 is installed on the reinforcement rod 22. The operator steps on the foot-operated air pump 29 to pump air into the air pipe 212. The gas enters the lifting cylinder 25 in one direction through the one-way valve 211 and the control air pipe 210, which can extend the lifting cylinder 25, thereby pushing the climate box adapter plate 26 to move up, opening the air release valve 214, and the gas in the lifting cylinder 25 is used through the control air pipe 210 and the air release pipe 213. The lifting cylinder 25 is shortened, which can allow the climate box adapter plate 26 to move down, thereby realizing the lifting and lowering control of the climate box adapter plate 26.

[0044] The pedal-type air pump 29, the air release valve 214 and the one-way valve 211 all adopt the existing technology.

[0045] The culture box scooping and dragging mechanism 8 is installed in the middle of the climate box adaptation platform 26.

[0046] The culture box scooping and dragging mechanism 8 includes a longitudinal through groove 81, a U-shaped push-pull rod 82, a shovel plate 83 and a blade strip 84. A longitudinal through groove 81 is opened in the middle of the climate chamber adapter plate 26, and a shovel plate 83 is slidably connected in the longitudinal through groove 81. The front end of the shovel plate 83 is fixedly connected to the U-shaped push-pull rod 82, and the rear end of the shovel plate 83 is connected to the blade strip 84. The top of the blade strip 84 is flush with the top surface of the climate chamber adapter plate 26, and the horizontal position of the top of the blade strip 84 is higher than the top surface of the shovel plate 83, and the bevel angle of the blade strip 84 is the same as the bevel angle of the inclined blade 215.

[0047] When it is necessary to take out a heavier culture basin from the partition in the artificial climate box, first align the bottom of the climate box adapter plate 26 with the top of the partition through the lifting control assembly, and then push the shovel plate 83 backwards through the U-shaped push-pull rod 82 to allow the shovel plate 83 to move backwards in the longitudinal groove 81, and the shovel plate 83 is inserted between the partition and the culture basin. The blade strip 84 makes it easier for the shovel plate 83 to be inserted into the bottom of the culture basin. After the shovel plate 83 completely scoops up the culture basin, the shovel plate 83 is pulled forward by the U-shaped push-pull rod 82. At this time, the edge of the front top of the blade strip 84 abuts against the bottom rear side of the culture basin, and the culture basin moves forward with the shovel plate 83. Since the edge of the front top of the blade strip 84 limits the bottom rear side of the culture basin, the culture basin is smoothly pushed forward to the upper side of the climate box adapter plate 26, and the heavier culture basin is smoothly transferred from the partition in the artificial climate box to the climate box adapter plate 26, which is convenient and fast for the transfer of the culture basin, saving time and effort.

[0048] When in use, the transverse sleeve 11, the transverse slide bar 12, and the longitudinal beam 13 form an I-shaped base. The universal wheel 14 facilitates the movement of the I-shaped base, and is convenient for moving back and forth between the artificial climate box and the test bench. In order to fix the I-shaped base after moving, a wheel brake is installed on the universal wheel 14. The opposite synchronous transverse movement assembly can drive the transverse slide bar 12 to move transversely relative to the transverse sleeve 11, and the distance between the two longitudinal beams 13 can be changed. If the distance between the two longitudinal beams 13 becomes larger, the I-shaped base will be more stable and will not be easily affected by the top structure and tip over. If the distance between the two longitudinal beams 13 becomes smaller, it is suitable for activities in a narrow space. At the same time, the change in the distance between the two longitudinal beams 13 can also make the climate box adaptation plate 26 closer to the artificial climate box or the test bench, avoiding the climate box adaptation plate 26 from being able to get close to the artificial climate box or the test bench due to the two longitudinal beams 13 hitting the bottom of the artificial climate box or the test bench too early. For example, when the distance between the two longitudinal beams 13 increases, the I-shaped base is close to the artificial climate box. The climate box can be located between the two longitudinal beams 13, so that the rear end of the climate box adapter plate 26 can be completely close to the front opening of the artificial climate box. The lifting control component is used to drive the climate box adapter plate 26 to move up and down, so that the top of the climate box adapter plate 26 is close to the partition in the artificial climate box. The sliding sleeve 27 and the vertical rod 21 are slidably connected to allow the climate box adapter plate 26 to move up and down stably. The setting of the inclined blade 215 is conducive to the culture dish sliding along the inclined surface of the inclined blade 215 to the upper side of the climate box adapter plate 26, and the culture box shovel The lifting and dragging mechanism 8 moves backward relative to the climate chamber adapter plate 26, and the culture box scooping and dragging mechanism 8 can scoop up the culture dish from the bottom of the artificial climate chamber, and then the culture box scooping and dragging mechanism 8 moves forward relative to the climate chamber adapter plate 26 to drag the scooped culture dish forward to the upper side of the climate chamber adapter plate 26. Since there is no limit on the four sides of the culture dish, this culture dish removal structure is suitable for heavier and larger culture boxes, but not for small culture bottles, because small culture bottles are easy to tip over when being scooped up.

[0049] For example 2, please refer to Figures 1 to 12 This embodiment provides a technical solution: a movable lifting platform for an artificial climate box. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0050] It also includes a first-level limiting mechanism 3 for the table top, which includes a vertical slot 31, a first-level height adjustment component and a first-level limiting block 34. A vertical slot 31 is opened in the middle of the front side of the vertical rod 21, and a first-level height adjustment component is installed in the vertical slot 31. A first-level limiting block 34 is arranged on the front side of the first-level height adjustment component.

[0051] The first-level height adjustment assembly includes a lead screw 32, a lead screw nut block 33 and a hexagonal screw head 35. An operating groove is provided at the front side of the vertical rod 21 below the vertical slot 31. A vertical lead screw 32 is rotatably connected in the vertical slot 31. The bottom end of the lead screw 32 extends into the operating groove and is fixedly connected to the hexagonal screw head 35. A lead screw nut block 33 is matched and connected to the lead screw 32. The lead screw nut block 33 is vertically slidably connected to the vertical slot 31, and the lead screw nut block 33 is connected to the vertical slot 31. A primary limit block 34 is fixedly connected to the front side of 33. By means of a hexagonal screw head 35, the lead screw 32 is rotated clockwise, and the threaded action of the lead screw 32 and the lead screw nut block 33 drives the lead screw nut block 33 to move upward along the vertical slot 31, thereby driving the primary limit block 34 to move upward. By means of a hexagonal screw head 35, the lead screw 32 is rotated counterclockwise, and the lead screw 32 drives the lead screw nut block 33 to move downward along the vertical slot 31, thereby driving the primary limit block 34 to move downward.

[0052] Since the accuracy of using the bleed valve 214 to deflate the lifting cylinder 25 is generally poor, it is not easy to control the height of the climate box adapter plate 26 to correspond exactly to the upper side of the partition in the artificial climate box. Therefore, the height of the first-level limit block 34 is adjusted with the help of the first-level height adjustment component, so that the top of the first-level limit block 34 corresponds to the upper side of the partition in the artificial climate box, and then the bleed valve 214 is used to deflate the lifting cylinder 25 until the bottom of the sliding sleeve 27 on the climate box adapter plate 26 is supported by the top of the first-level limit block 34, and the accuracy requirement for deflation by the bleed valve 214 is relatively low.

[0053] For example 3, please refer to Figures 1 to 12 This embodiment provides a technical solution: a movable lifting platform for an artificial climate box. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0054] It also includes a secondary limiting mechanism 4 for the table, which includes a second vertical groove 41, a secondary height adjustment component, a second screw nut block 43, a one-way limiting block 44, a longitudinal groove 46 and a limiting spring 47. A second vertical groove 41 is provided on the front top of the vertical rod 21, and a second screw nut block 43 is installed in the second vertical groove 41 through the secondary height adjustment component. A longitudinal groove 46 is provided on the front side of the screw nut block 43, and a one-way limiting block 44 is longitudinally slidably connected in the longitudinal groove 46. The rear side of the one-way limiting block 44 is connected to the rear side of the longitudinal groove 46 through a limiting spring 47, and a guiding slope is provided on the front bottom of the one-way limiting block 44.

[0055] The secondary height adjustment assembly includes a lead screw 42 and a hexagonal screw head 45. A vertical lead screw 42 is rotatably connected in the vertical slot 41. The top of the lead screw 42 extends to the upper side of the top beam 23 and is fixedly connected with the hexagonal screw head 45. The lead screw 42 is matched with the screw hole on the lead screw nut block 43. The lead screw nut block 43 is vertically slidably connected with the vertical slot 41. By rotating the lead screw 42 clockwise with the help of the hexagonal screw head 45, the lead screw 42 drives the lead screw nut block 43 to move upward along the vertical slot 41. By rotating the lead screw 42 counterclockwise with the help of the hexagonal screw head 45, the lead screw 42 drives the lead screw nut block 43 to move downward along the vertical slot 41.

[0056] Since there are more than one partitions in the artificial climate box, if there are multiple partitions in the artificial climate box, it is necessary to adjust the height of the first-level limit block 34 multiple times when only the first-level limit mechanism 3 of the table is set, which affects the efficiency of the climate box adaptation table 26 to align with different partitions. Therefore, a second-level limit mechanism 4 of the table is set, and the second-level height adjustment component drives the screw nut block 23 to move up and down in the vertical groove 241, so that the one-way limit block 44 limits the bottom of the sliding sleeve 27 on the climate box adaptation table 26, so that the climate box adaptation table 26 can correspond to the partition on the upper side of the artificial climate box. When the lifting cylinder 25 is extended, if the sliding sleeve 27 is located on the lower side of the one-way limit block 44, the sliding sleeve 27 first contacts the guiding inclined surface on the front side of the one-way limit block 44, allowing the one-way limit block 43 to move up and down in the vertical groove 241. The limit block 44 gradually retracts into the longitudinal groove 46. At this time, the limit spring 47 is compressed, and then the sleeve 27 slides over the top of the one-way limit block 44. The limit spring 47 extends, pushing the front end of the one-way limit block 44 out of the longitudinal groove 46, and then the lifting cylinder 25 is deflated, the lifting cylinder 25 is shortened, and the sleeve 27 descends along the vertical rod 21 until the sleeve 27 is supported and limited by the top surface of the one-way limit block 44. Since the sleeve 27 can be limited by the secondary limit mechanism 4 of the table, the climate box can be adapted to the table 26 to quickly align with the partition on the upper side of the artificial climate box, and the sleeve 27 can also cross the one-way limit block 44 downward, so that the sleeve 27 is limited by the primary limit mechanism 3 of the table, so that the climate box can be adapted to the table 26 to quickly align with the partition near the lower side of the artificial climate box.

[0057] Example 4, please refer to Figures 1 to 12 This embodiment provides a technical solution: a movable lifting platform for an artificial climate box. The structure of this embodiment is roughly the same as that of the third embodiment, except that:

[0058] It also includes a longitudinal movement mechanism 5, a height adjustment mechanism 6 and a multi-culture bottle clamping mechanism 7. The left and right sides of the top of the climate box adaptation platform 26 are respectively connected to the two ends of the longitudinal movement mechanism 5, and the top of the longitudinal movement mechanism 5 is connected to the front end of the multi-culture bottle clamping mechanism 7 through the height adjustment mechanism 6. The longitudinal movement mechanism 5 is used to drive the height adjustment mechanism 6 and the multi-culture bottle clamping mechanism 7 to move forward and backward relative to the climate box adaptation platform 26. The height adjustment mechanism 6 is used to change the height of the multi-culture bottle clamping mechanism 7 so that the multi-culture bottle clamping mechanism 7 is aligned with the middle of the culture bottle in the artificial climate box. When in use, the longitudinal movement mechanism 5 is used to drive the rear end of the multi-culture bottle clamping mechanism 7 to extend into the artificial climate box, and the multi-culture bottle clamping mechanism 7 clamps the middle of the culture bottle. Then, the longitudinal movement mechanism 5 is used to drive the multi-culture bottle clamping mechanism 7 to move forward, and the multi-culture bottle clamping mechanism 7 brings the culture bottle forward out of the artificial climate box until the bottom of the culture bottle moves to the upper side of the climate box adaptation platform 26. The climate box adaptation platform 26 supports the bottom of the culture bottle, and can stably transfer the culture bottle in the artificial climate box.

[0059] Specifically, the longitudinal movement mechanism 5 includes a longitudinal slide rail 51, a longitudinal slider 52, an arch frame 56 and a longitudinal movement blocking assembly. Two longitudinal slide rails 51 are fixedly connected to the left and right sides of the top of the climate box adapter plate 26, and two longitudinal sliders 52 are fixedly connected to the two ends of the arch frame 56. The two longitudinal sliders 52 are respectively slidably connected to the two longitudinal slide rails 51, and a longitudinal movement blocking assembly is installed at the bottom of each longitudinal slider 52.

[0060] The longitudinal movement blocking assembly includes a blind hole 53, an installation spring 54, and a limiting ball 55. A plurality of hemispherical grooves are provided at equal distances in the longitudinal direction in the longitudinal slide rail 51. A blind hole 53 is provided at the bottom of the longitudinal slider 52. The limiting ball 55 is connected to the blind hole 53 through the installation spring 54. When the longitudinal slider 52 slides along the longitudinal slide rail 51, as long as the limiting ball 55 corresponds to one of the hemispherical grooves, the elastic force of the installation spring 54 squeezes the limiting ball 55 into the corresponding hemispherical groove. With the help of the resistance brought by the cooperation of the limiting ball 55 and the hemispherical groove, the position of the longitudinal slider 52 in the longitudinal slide rail 51 is fixed. When the arch frame 56 is pushed hard, the longitudinal slider 52 overcomes the resistance brought by the cooperation of the limiting ball 55 and the hemispherical groove, allowing the longitudinal slider 52 to slide along the longitudinal slide rail 51. At this time, the installation spring 54 is compressed and the limiting ball 55 retracts into the blind hole 53.

[0061] The arch frame 56 is pushed and pulled forward and backward, and can move forward and backward along the longitudinal slide rail 51 through the longitudinal slider 52, thereby driving the height adjustment mechanism 6 and the multi-culture bottle clamping mechanism 7 to move freely forward and backward. Since the forward and backward movement of the arch frame 56 may be uncontrolled, a longitudinal movement blocking component is provided to prevent the longitudinal slider 52 from sliding uncontrollably along the longitudinal slide rail 51.

[0062] Specifically, the height adjustment mechanism 6 includes an adjustment transverse plate 61 and a height adjustment component, and the top of the arch frame 56 is connected to the top of the adjustment transverse plate 61 through the height adjustment component.

[0063] The height adjustment assembly includes a tapered roller bearing 62, a lifting screw nut 63, a height adjustment screw 64, a hand wheel 65, and a column 66. The middle part of the arch frame 56 is inlaid with a lifting screw nut 63, which is threadedly connected to the height adjustment screw 64. The top of the height adjustment screw 64 is fixedly connected with a hand wheel 65. The bottom end of the height adjustment screw 64 is rotatably connected to the middle part of the adjustment cross plate 61 through the tapered roller bearing 62. The left and right ends of the top of the adjustment cross plate 61 are respectively fixedly connected to the bottoms of the two columns 66. The column 66 is slidably connected to the two sliding holes on the arch frame 56 respectively. The height adjustment screw 64 is rotated clockwise with the help of the hand wheel 65. Since the column 66 cooperates with the arch frame 56 to allow the adjustment cross plate 61 to only move up and down, the height adjustment screw 64 moves up relative to the lifting screw nut 63 and the arch frame 56, and the height adjustment screw 64 drives the adjustment cross plate 61 to move up through the tapered roller bearing 62. The height adjustment screw 64 is rotated counterclockwise with the help of the hand wheel 65, and the height adjustment screw 64 drives the adjustment cross plate 61 to move down through the tapered roller bearing 62.

[0064] The height adjustment assembly is used to drive the adjustment horizontal plate 61 to move up and down relative to the arch frame 56, so as to change the height of the multi-culture bottle clamping mechanism 7 so that the multi-culture bottle clamping mechanism 7 is aligned with the middle of the culture bottle in the artificial climate box.

[0065] Specifically, the multi-culture bottle clamping mechanism 7 includes a folding shaft 71, a folding plate 72, a lower baffle plate 73, an end plate 74, an installation cavity 75, a transverse plate 77, a lever 78, a rectangular through groove 79, a culture bottle groove 710, a side through groove 711, a clamping rod 712, a stopper 713 and a return spring 714. The rear end of the adjustment transverse plate 61 is movably connected to the front end of the folding plate 72 through the folding shaft 71, and the rear end bottom of the adjustment transverse plate 61 is fixedly connected to the lower baffle plate 73 by screws. The middle part of the folding plate 72 is provided with an installation cavity 75, and the opening at the right end of the folding plate 72 is fixedly connected to the end plate 74 by screws. The end plate 74 can be removed by loosening the screws here, so as to facilitate the installation of components in the installation cavity 75. A plurality of culture bottle grooves 710 are provided at the rear end, and a side through groove 711 is provided on the right side of each culture bottle groove 710. The front end of the side through groove 711 is connected to the installation cavity 75. A transverse plate 77 is connected to the installation cavity 75 for transverse sliding. The right side of the transverse plate 77 is connected to the end plate 74 through a reset spring 714. A clamping rod 712 is fixedly connected to the position corresponding to the side through groove 711 on the rear side of the transverse plate 77. The rear end of the clamping rod 712 extends to the rear end of the side through groove 711, and a stopper 713 is fixedly connected to the left side of the rear end of the clamping rod 712. Two rectangular through grooves 79 are respectively provided on the left and right sides of the top of the folding plate 72. A pull rod 78 is fixedly connected to the position corresponding to the middle of the rectangular through groove 79 on the top of the transverse plate 77.

[0066] The multiple culture bottle clamping mechanism 7 further comprises a limit bar 76 . The limit bar 76 is arranged at the bottom of the mounting cavity 75 . The limit bar 76 is connected to the transverse moving plate 77 in a transverse sliding manner.

[0067] In this embodiment, the number of the culture bottle grooves 710 is four.

[0068] The number of culture bottle grooves 710 is the same as the number of culture bottles arranged side by side in the artificial climate box. When there is no need to transfer the culture bottles in the artificial climate box, the folding plate 72 is folded upward relative to the adjusting cross plate 61 through the folding shaft 71, so that the climate box adaptation table 26 and the culture box scooping and dragging mechanism 8 can cooperate to transfer the culture basins in the artificial climate box. When it is necessary to transfer the culture bottles in the artificial climate box, the folding plate 72 is flipped to a horizontal state, and the lower baffle plate 73 limits the bottom of the folding plate 72 to keep the folding plate 72 stably in a horizontal state. With the help of the longitudinal movement mechanism 5, the rear end of the folding plate 72 is extended into the artificial climate box, so that multiple culture bottle grooves 710 correspond to multiple culture bottles arranged side by side in the artificial climate box, and then the lever 78 is pulled to the right, the transverse plate 77 moves right relative to the folding plate 72, the reset spring 714 is compressed, and the transverse plate 77 drives each clamping rod 712 to move right in its corresponding side through groove 711, and The blocks 713 are also retracted into the corresponding side grooves 711 along with the clamping rods 712, and then the folding plate 72 is continued to move backward with the help of the longitudinal movement mechanism 5. As the folding plate 72 moves backward, multiple culture bottles arranged side by side begin to be located in multiple culture bottle grooves 710, and the lever 78 is released, and the return spring 714 is restored and extended, pushing the transverse plate 77 to move left relative to the folding plate 72. The transverse plate 77 drives each block 713 to move left through each clamping rod 712, and the block 713 blocks the rear side of the culture bottle, and then the arch frame 56 in the longitudinal movement mechanism 5 is pulled forward, and the longitudinal movement mechanism 5 allows the folding plate 72 to move forward. The block 713 pushes the culture bottle forward on the partition in the artificial climate box along with the folding plate 72 until the bottom of the culture bottle slides onto the climate box adaptation table 26. At this time, it is convenient to transfer the culture bottle, and multiple culture bottles placed side by side can be taken out at one time, which has high transfer efficiency and is convenient and quick to transfer the culture bottles.
