Description

Technical Field

[0001] The present invention relates to the technical field of strain preservation equipment, and specifically relates to a strain preservation device that is convenient for taking and placing, and more specifically also relates to a usage method of a strain preservation device that is convenient for taking and placing. Background Technique

[0002] A strain is a microorganism used as a living cell catalyst in the fermentation process, including four categories: bacteria, actinomycetes, yeasts, and molds. It is sourced from a large number of microorganisms in nature, from which useful strains are isolated and screened, and then improved and stored for use in production.

[0003] In existing strain storage devices, when storing strains, a strain preservation box is usually used. After the strain preservation box holds the strains, it is placed into a preservation box, and the preservation box freezes and preserves the strains.

[0004] In the above solution, the strain preservation boxes are stacked in the preservation box. When a staff member needs to take out a strain, and the strain preservation box where the strain is located is at the lower layer of the preservation box, the staff member needs to take out all the strain preservation boxes above to take out the required strain, making the process of taking and placing the strains relatively complicated and not facilitating the staff to regularly inspect and re-passage the strains stored in the freezer.

[0015] A method for using a strain preservation device that is convenient for taking and placing includes the following steps:

[0016] S1. When placing the strain, open the sealing cover. The first driving mechanism first rotates the first storage rack to the horizontal state. Under the action of the counterweight, the installation cylinder rotates around the axis connection between the connecting ring and the first rectangular frame, so that the installation cylinder is always in the vertical state.

[0017] S2. Open the cover plate, put the strain into the installation cylinder, and close the cover plate.

[0018] S3. The first driving mechanism rotates the first storage rack to the vertical state, and then rotates the second storage rack to the horizontal state. Repeat the above process to store the strain in the box body, and close the sealing cover.

[0019] S4. When taking the strain, according to the strain to be taken, the first driving mechanism rotates the first storage rack or the second storage rack where the strain is located to the horizontal state, which is convenient for the staff to take out the strain.

[0020] The beneficial effects of the present application compared with the prior art are as follows:

[0021] 1. The invention is provided with a first storage mechanism and a number of storage units. When putting the strain into the preservation box, the first driving mechanism rotates the first storage rack to the horizontal state. During the rotation of the first storage rack, the installation cylinder is affected by the counterweight, and the installation cylinder rotates around the axis connection with the connecting ring, so that the installation cylinder is always in the vertical state. After the first storage rack rotates to the horizontal state, open the cover plate on the installation cylinder, put the strain in the installation cylinder, and then cover the cover plate. After a number of installation cylinders on the first storage rack are filled with the strain, the first driving mechanism rotates the first storage rack to the vertical state. During this process, the installation cylinder is always in the vertical state. Then the first driving mechanism rotates the second storage rack to the horizontal state, repeats the above process to fill a number of installation cylinders in the second storage rack, and finally the first driving mechanism rotates the second storage rack to the vertical state. When taking the strain, the first storage mechanism performs the same actions as above, rotates the strain to be taken to the horizontal state, so as to facilitate the staff to regularly check and re-passage the strains stored in the freezer.

[0022] 2. The present invention is provided with a first motor, a first main gear, a first driving arm and a second driving arm. When the first motor operates, it drives the rotation of the first main gear column. The first main gear column drives the first auxiliary gear column and the second auxiliary gear column to rotate simultaneously. The first auxiliary gear column drives the rotation of the first rotating shaft, the first rotating shaft drives the rotation of the first connecting seat, and the first connecting seat drives the rotation of the first storage rack. The second auxiliary gear column drives the rotation of the second rotating shaft, the second rotating shaft drives the rotation of the second connecting seat, and the second connecting seat drives the rotation of the second storage rack. When the first rotating shaft drives the first storage rack to rotate from the horizontal state to the vertical state, the second rotating shaft simultaneously drives the second storage rack to rotate from the vertical state to the horizontal state, enabling the first storage rack and the second storage rack to move simultaneously, avoiding the rotation of the second storage rack after the movement of the first storage rack is completed, thereby reducing the interval time for placing or removing the strains from the first storage rack to the second storage rack and improving work efficiency.

[0023] 3. The present invention is provided with a first transmission structure and a second transmission structure. The first auxiliary gear column and the first rotating shaft are connected by a bearing, and the second auxiliary gear column and the second rotating shaft are connected by a bearing. When the first main gear column drives the first auxiliary gear column and the second auxiliary gear column to rotate, the first auxiliary gear column and the second auxiliary gear column will not drive the first rotating shaft and the second rotating shaft to rotate. When it is necessary to rotate the first rotating shaft but not the second rotating shaft, the second transmission structure disconnects the transmission connection between the second rotating shaft and the second auxiliary gear column, and the second transmission disk in the first transmission structure moves towards the first transmission disk, and the first transmission disk and the second transmission disk are mutually engaged. The rotation of the first auxiliary gear column drives the rotation of the first transmission disk, the first transmission disk drives the rotation of the second transmission disk, and the second transmission disk drives the first rotating shaft to rotate through a slider. When it is necessary to rotate the second rotating shaft but not the first rotating shaft, the first transmission structure disconnects the transmission connection between the first rotating shaft and the first auxiliary gear column, and the second transmission structure connects the second rotating shaft and the second auxiliary gear column for transmission, so that the first storage rack and the second storage rack can be in the horizontal or vertical state simultaneously.

Detailed implementation manners

[0037] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0038] Refer to Figures 1 to 12As shown: A strain preservation device that is convenient for taking and placing, including a preservation box 1. The preservation box 1 includes a box body 11. The box body 11 has a cavity with an upward opening. A sealing cover 12 is provided at the upper end of the box body 11. A walking structure 13 for facilitating the movement of the preservation box 1 is provided at the lower end of the box body 11. A first storage mechanism 2 is provided inside the box body 11. The first storage mechanism 2 includes a first storage rack 21 and a second storage rack 22. The first storage rack 21 and the second storage rack 22 are symmetrically arranged with respect to the middle plane of the box body 11. A number of first rectangular installation slots 211 are formed on the surface of the first storage rack 21. A number of second rectangular installation slots 221 are formed on the surface of the second storage rack 22. A first driving mechanism 23 for driving the rotation of the first storage rack 21 and the second storage rack 22 is provided outside the box body 11. Storage units 3 are provided in both the first rectangular installation slots 211 and the second rectangular installation slots 221. The storage unit 3 includes a first rectangular frame 31. The first rectangular frame 31 is arranged parallel to the first storage rack 21. A connecting ring 32 is provided inside the first rectangular frame 31. Both ends of the connecting ring 32 are pivotally connected to both ends of the first rectangular frame 31. An installation cylinder 33 is provided in the middle of the connecting ring 32. The installation cylinder 33 has a cavity with an upward opening. A counterweight 34 is provided at the lower end of the installation cylinder 33. A cover plate 35 is provided at the upper end of the installation cylinder 33.

[0039] When putting strains into the preservation box 1, the staff first opens the sealing cover 12. Then, the first driving mechanism 23 rotates the first storage rack 21 to a horizontal state. During the rotation of the first storage rack 21, the installation cylinder 33 is affected by the counterweight 34, and the installation cylinder 33 rotates around the pivot connection with the connecting ring 32, so that the installation cylinder 33 is always in a vertical state. After the first storage rack 21 rotates to the horizontal state, the cover plate 35 on the installation cylinder 33 is opened, the strains are placed in the installation cylinder 33, and then the cover plate 35 is covered. After a number of installation cylinders 33 on the first storage rack 21 are filled with strains, the first driving mechanism 23 rotates the first storage rack 21 to a vertical state. During this process, the installation cylinder 33 is always in a vertical state. Then, the first driving mechanism 23 rotates the second storage rack 22 to a horizontal state, and repeats the above process to fill a number of installation cylinders 33 in the second storage rack 22. Finally, the first driving mechanism 23 rotates the second storage rack 22 to a vertical state. When taking out the strains, the first storage mechanism 2 performs the same actions as above, rotating the strains to be taken out to a horizontal state, so as to facilitate the staff to regularly inspect and re-passage the strains stored in the freezer.

[0040] Refer to Figure 4 、 Figure 6 and Figure 7As shown: The first driving mechanism 23 includes a first motor 231. One end of the first motor 231 is provided with a first main gear column 232. The first main gear column 232 is connected to the output shaft of the first motor 231. On both sides of the first main gear column 232, a first driving arm 233 and a second driving arm 234 are respectively provided. The first driving arm 233 includes a first rotating shaft 2331, a first connecting seat 2332, and a first sub-gear column 2333. One end of the first rotating shaft 2331 penetrates the box body 11, and a first connecting seat 2332 is sleeved on one end of the first rotating shaft 2331. The first connecting seat 2332 is connected to the first storage rack 21. The other end of the first rotating shaft 2331 is connected to the first sub-gear column 2333. The first sub-gear column 2333 is meshed and connected to the first main gear column 232. The second driving arm 234 includes a second rotating shaft 2341, a second connecting seat 2342, and a second sub-gear column 2343. One end of the second rotating shaft 2341 penetrates the box body 11, and a second connecting seat 2342 is sleeved on one end of the second rotating shaft 2341. The second connecting seat 2342 is connected to the second storage rack 22. The other end of the second rotating shaft 2341 is provided with a second sub-gear column 2343. The second sub-gear column 2343 is meshed and connected to the first main gear column 232.

[0041] When the first motor 231 works, it drives the first main gear column 232 to rotate. The first main gear column 232 drives the first sub-gear column 2333 and the second sub-gear column 2343 to rotate simultaneously. The first sub-gear column 2333 drives the first rotating shaft 2331 to rotate. The first rotating shaft 2331 drives the first connecting seat 2332 to rotate. The first connecting seat 2332 drives the first storage rack 21 to rotate. The second sub-gear column 2343 drives the second rotating shaft 2341 to rotate. The second rotating shaft 2341 drives the second connecting seat 2342 to rotate. The second connecting seat 2342 drives the second storage rack 22 to rotate. When the first rotating shaft 2331 drives the first storage rack 21 to rotate from the horizontal state to the vertical state, the second rotating shaft simultaneously drives the second storage rack 22 to rotate from the vertical state to the horizontal state, so that the first storage rack 21 and the second storage rack 22 move simultaneously, avoiding the second storage rack 22 rotating after the first storage rack 21 has completed its movement, thereby reducing the interval time for placing or taking out the strains from the first storage rack 21 to the second storage rack 22 and improving work efficiency.

[0042] Refer to Figure 6 、 Figure 7 and Figure 8As shown in the figure: Sliding grooves are provided on the surfaces of the first rotating shaft 2331 and the second rotating shaft 2341. A first transmission structure 235 is sleeved on the first rotating shaft 2331, and a second transmission structure 236 is sleeved on the second rotating shaft 2341. The first transmission structure 235 includes first transmission discs 2351. There are two first transmission discs 2351, and the two first transmission discs 2351 are respectively connected to both ends of the first sub-gear column 2333. A second transmission disc 2352 is arranged on one side of the first transmission disc 2351. A slider 2353 is arranged in the middle of the second transmission disc 2352. The slider 2353 is slidably arranged in the sliding groove. The second transmission structure 236 has the same structure as the second transmission structure 236.

[0043] Since the first main gear column 232 drives the first sub-gear column 2333 and the second sub-gear column 2343 to rotate simultaneously, the rotation directions of the first sub-gear column 2333 and the second sub-gear column 2343 are the same, resulting in the first storage rack 21 and the second storage rack 22 not being able to be in the horizontal or vertical state simultaneously. By providing the first transmission structure 235 and the second transmission structure 236, the first sub-gear column 2333 and the first rotating shaft 2331 are connected by a bearing, and the second sub-gear column 2343 and the second rotating shaft 2341 are connected by a bearing. When the first main gear column 232 drives the first sub-gear column 2333 and the second sub-gear column 2343 to rotate, the first sub-gear column 2333 and the second sub-gear column 2343 will not drive the first rotating shaft 2331 and the second rotating shaft 2341 to rotate. When it is necessary for the first rotating shaft 2331 to rotate and the second rotating shaft 2341 does not need to rotate, the second transmission structure 236 disconnects the transmission connection between the second rotating shaft 2341 and the second sub-gear column 2343. The second transmission disc 2352 in the first transmission structure 235 moves towards the first transmission disc 2351, and the first transmission disc 2351 and the second transmission disc 2352 are engaged with each other. The first sub-gear column 2333 rotates to drive the first transmission disc 2351 to rotate, the first transmission disc 2351 drives the second transmission disc 2352 to rotate, and the second transmission disc 2352 drives the first rotating shaft 2331 to rotate through the slider 2353. When it is necessary for the second rotating shaft 2341 to rotate and the first rotating shaft 2331 does not need to rotate, the first transmission structure 235 disconnects the transmission connection between the first rotating shaft 2331 and the first sub-gear column 2333, and the second transmission structure 236 transmits the power between the second rotating shaft 2341 and the second sub-gear column 2343, so that the first storage rack 21 and the second storage rack 22 can be in the horizontal or vertical state simultaneously.

[0044] Refer to Figure 6 、 Figure 7 and Figure 8As shown: At the lower ends of two second drive disks 2352, there are second rectangular frames 2354. Inside the second rectangular frames 2354, there are double-headed screws 2355. The two ends of the double-headed screws 2355 are respectively connected to the two ends of the second rectangular frames 2354. Two moving blocks 2356 are sleeved on the double-headed screws 2355. At the upper ends of the two moving blocks 2356, there are first connecting blocks 2357. The two first connecting blocks 2357 are respectively connected to the two second drive disks 2352. One end of the double-headed screw 2355 is provided with a second motor 2358.

[0045] When it is necessary to drive-connect the first rotating shaft 2331 and the first sub-gear column 2333, the second motor 2358 drives the double-headed screw 2355 to rotate. The double-headed screw 2355 drives the two moving blocks 2356 to approach each other. The two moving blocks 2356 respectively drive the two first connecting blocks 2357 to approach each other. The first connecting blocks 2357 drive the second drive disks 2352 to move. When the second drive disks 2352 abut against each other, the second drive disks 2352 stop moving. Since the clamping blocks on the first drive disk 2351 and the second drive disks 2352 may not be in an aligned state, at this time, the first drive disk 2351 and the second drive disks 2352 have two states: clamped and unclamped. When the second drive disks 2352 are not clamped with the first drive disk 2351, the first drive disk 2351 rotates under the drive of the first main gear column 232. At the same time, the second drive disks 2352 continue to move towards the first drive disk 2351, and the second drive disks 2352 are clamped into the first drive disk 2351, so that the first drive disk 2351 and the second drive disks 2352 will finally be in a clamped state.

[0046] Refer to Figure 4 and Figure 9 As shown: At one end of the first rotating shaft 2331, there is a first locking structure 24. The first locking structure 24 includes a fixed disk 241. The axis of the fixed disk 241 is collinear with the axis of the first rotating shaft 2331. The fixed disk 241 is fixedly connected to the first rotating shaft 2331. On the fixed disk 241, there are a first notch groove 2411 and a second notch groove 2412. The included angle between the first notch groove 2411 and the second notch groove 2412 is 90 degrees. At the lower end of the fixed disk 241, there is a clamping block 242. The clamping block 242 cooperates with the first notch groove 2411 and the second notch groove 2412. At the lower end of the clamping block 242, there is a second connecting block 243. The second connecting block 243 is connected to the clamping block 242. At the lower end of the second connecting block 243, there is an electric push rod 244. One end of the electric push rod 244 is connected to the second connecting block 243. The other end of the electric push rod 244 is provided with a first bracket 245.

[0047] After the first storage rack 21 rotates to the horizontal state, the connection between the first secondary gear column 2333 and the first rotating shaft 2331 is disconnected. Under the action of the first storage rack 21, the first rotating shaft 2331 will rotate, and the first storage rack 21 will rotate back to the vertical state. By setting the locking structure, in the initial state, the block 242 is stuck in the first notch groove 2411 under the action of the electric push rod 244, so that the fixed disk 241 cannot rotate. When it is necessary to rotate the first storage rack 21, the electric push rod 244 pulls out the block 242 from the first notch groove 2411. After the first rotating shaft 2331 rotates 90 degrees, the second notch groove 2412 is aligned with the block 242, and the electric push rod 244 pushes the block 242 into the second notch groove 2412, so that the fixed disk 241 cannot rotate, thereby preventing the first rotating shaft 2331 from rotating under the action of the first storage rack 21.

[0048] Refer to Figure 9 As shown: A limit bracket 245 is provided between the second connecting block 243 and the electric push rod 244. The output shaft of the electric push rod 244 passes through the limit bracket 245 and is connected to the second connecting block 243. First guiding columns 246 are provided on both sides of the electric push rod 244. One end of the first guiding column 246 is connected to the second connecting block 243, and the other end of the first guiding column 246 passes through the limit bracket 245 and is slidably connected to the limit bracket 245.

[0049] When the block 242 is stuck in the second notch groove 2412 to prevent the fixed disk 241 from rotating, the output shaft of the electric push rod 244 will be subjected to a large force. By setting the limit bracket 245 and the second guiding column 3633, when the electric push rod 244 pushes the block 242 to move, the block 242 drives the second guiding column 3633 to move. The lower end of the second guiding column 3633 slides in the limit bracket 245, and the limit bracket 245 provides a supporting force for the second guiding column 3633, thereby reducing the force on the output shaft of the electric push rod 244 and preventing the electric push rod 244 from being damaged.

[0050] Refer to Figure 5 、 Figure 10 and Figure 11As shown in the figure: A fixing structure 36 is arranged inside the mounting cylinder 33. The fixing structure 36 includes a base 361 which is fixedly connected to the inner bottom surface of the mounting cylinder 33. A number of upright columns 362 are arranged in a circular array on the base 361. One end of each upright column 362 is connected to the base 361, and an elastic connection structure 363 is arranged at the other end of the upright column 362. The elastic connection structure 363 includes a first connecting plate 3631, a second connecting plate 3632, a second guiding column 3633 and a first compression spring 3634. The first connecting plate 3631 is fixedly connected to the upright column 362. The second connecting plate 3632 is arranged on one side of the first connecting plate 3631 and is parallel to the first connecting plate 3631. There are two second guiding columns 3633. One ends of the two second guiding columns 3633 are respectively connected to the two ends of the second connecting plate 3632. The other ends of the second guiding columns 3633 pass through the first connecting plate 3631 and are slidably connected to the first connecting plate 3631. The first compression spring 3634 is sleeved on the second guiding column 3633. A mold frame 364 is arranged on one side of the second connecting plate 3632. A roller 365 is arranged in the middle of the mold frame 364. A connecting column 366 is arranged at the lower end of the mold frame 364. The upper end of the connecting column 366 is connected to the mold frame 364. An installation plate 367 is arranged at the lower end of the connecting column 366. A gasket 368 is arranged on the surface of the installation plate 367.

[0051] When the staff puts the strains into the mounting cylinder 33, during the process that the first storage rack 21 rotates from the horizontal state to the vertical state, the mounting cylinder 33 will swing to a certain extent, which easily causes the strains to collide with the mounting cylinder 33. By setting the fixing structure 36, when the staff puts the strains into the mounting cylinder 33, the lower end of the strains is stuck between a number of rollers 365, and then a downward force is applied to the strains. At the same time, the elastic connection structure 363 contracts, so that the strains can pass through between a number of rollers 365. The periphery of the strains contacts the gaskets 368, and a number of gaskets 368 clamp the strains under the action of the elastic connection structure 363, thereby realizing the fixed installation of the strains in the mounting cylinder 33 and avoiding the collision between the strains and the mounting cylinder 33.

[0052] Refer to Figure 5 As shown in the figure: One end of the cover plate 35 is provided with a main rotating shaft 37. One end of the main rotating shaft 37 passes through the cover plate 35 and is axially connected to the mounting cylinder 33. A second compression spring 38 is sleeved on the main rotating shaft 37. One end of the second compression spring 38 is connected to the cover plate 35, and the other end of the second compression spring 38 is connected to the main rotating shaft 37. The other end of the cover plate 35 is provided with a bolt 39. One end of the bolt 39 passes through the cover plate 35 and is connected to the mounting cylinder 33.

[0053] The temperature inside the storage box 1 is relatively low, and the cover plate 35 covers the installation cylinder 33. In a low-temperature environment, the cover plate 35 is prone to sticking to the installation cylinder 33, making it inconvenient to push the cover plate 35 to rotate around the main rotating shaft 37. Therefore, a second compression spring 38 is sleeved on the main rotating shaft 37, and the second compression spring 38 applies a downward force on the cover plate 35 to make the cover plate 35 closely adhere to the installation cylinder 33. When opening the cover plate 35, pull out the bolt 39, and then lift the cover plate 35 upward to separate the cover plate 35 from the installation cylinder 33, thereby facilitating the staff to open the cover plate 35 on the installation cylinder 33.

[0054] Refer to Figure 1 and Figure 12 As shown in: On both sides inside the box body 11, a second storage mechanism 4 and a third storage mechanism 5 are respectively arranged. The second storage mechanism 4 includes a third storage rack 41. A number of third rectangular installation slots 411 are opened on the third storage rack 41. One end of the third storage rack 41 is provided with a second driving mechanism 42, and the other end of the third storage rack 41 is provided with a second locking structure 43. The third storage mechanism 5 includes a fourth storage rack 51. A number of fourth rectangular installation slots 511 are opened on the fourth storage rack 51. One end of the fourth storage rack 51 is provided with a third driving mechanism 52, and the other end of the fourth storage rack 51 is provided with a third locking structure 53.

[0055] The first storage rack 21 and the second storage rack 22 are filled with strains and are stored in the storage box 1. The second driving mechanism 42 rotates the third storage rack 41 to a horizontal state, and the third driving mechanism 52 rotates the fourth storage rack 51 to a horizontal state. Then, a number of storage units 3 on the third storage rack 41 and the fourth storage rack 51 are filled with strains. The second driving mechanism 42 retracts the third storage rack 41 into the storage box 1, and the third driving mechanism 52 retracts the fourth storage rack 51 into the storage box, thereby increasing the amount of strains stored in the storage box 1.

[0056] A method for using a strain preservation device that is convenient for taking and placing includes the following steps:

[0057] S1, when placing strains, open the sealing cover 12. The first driving mechanism 23 first rotates the first storage rack 21 to a horizontal state. Under the action of the counterweight 34, the installation cylinder 33 rotates around the hinge point of the connecting ring 32 and the first rectangular frame 31, so that the installation cylinder 33 is always in a vertical state;

[0058] S2, open the cover plate 35, put the strains into the installation cylinder 33, and close the cover plate 35;

[0059] S3, the first driving mechanism 23 rotates the first storage rack 21 to a vertical state, and then rotates the second storage rack 22 to a horizontal state. Repeat the above process to store the strains in the box body 11, and close the sealing cover 12;

[0060] S4. When taking the strains, according to the strains to be taken, the first driving mechanism 23 rotates the first storage rack 21 or the second storage rack 22 where the strains are located to the horizontal state, facilitating the staff to take out the strains.

[0061] The above embodiments only express one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
