Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a docking device for aseptic transfer of tissue culture seedlings. Background Technology

[0002] In the process of high-quality development of the Chinese medicinal materials industry, new methods and technologies for the selection and breeding of superior varieties and the purification and rejuvenation of strains are the core support for improving the quality and yield of medicinal materials. Meanwhile, the breeding of rare and endangered wild animal and plant medicinal materials, standardized planting or breeding, and ecological protection technologies are the key guarantees for the sustainable utilization of Chinese medicinal materials resources. Innovations in standardized planting or breeding technologies and processing techniques for Chinese medicinal materials have further promoted the standardization and modernization of the Chinese medicinal materials industry chain. Plant tissue culture technology, as an important technical means in the above fields, plays an irreplaceable role in the rapid breeding of superior varieties of Chinese medicinal materials, the cultivation of virus-free seedlings, and the in vitro preservation of rare species. The docking device used for aseptic transfer of tissue culture seedlings is a key tool to ensure aseptic transfer of Chinese medicinal material tissue culture seedlings in a sterile environment. It can quickly and conveniently connect relevant pipelines or containers, effectively avoid contamination during the transfer process, and is simple and intuitive to operate without complicated auxiliary tools. It is safe and reliable to use.

[0003] Existing connectors achieve a static seal by using the preload of a spring in the conduit to push the sealing cap against the inner wall of the container. However, the spring, being under constant compression, will experience reduced elasticity due to metal fatigue, eventually leading to insufficient preload. This causes the sealing cap to loosen and leak. Current technology uses external threaded tubes at both ends of the connector to directly screw into the internal threaded bottle neck of the container, ensuring a proper fit between the container interface and the connector joint. However, in this connection method, the pitch, tooth profile, and diameter parameters of the external and internal threads must be strictly matched. When using different sizes of containers to transfer tissue culture seedlings of Chinese medicinal herbs, the container and connector may not completely seal, resulting in reduced or even ineffective sterility. This method is also unsuitable for transfer containers of different sizes. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a docking device for aseptic transfer of tissue culture seedlings, aiming to improve the problem in the prior art that the container and docking device cannot be completely sealed, resulting in the attenuation or even failure of the aseptic effect, and the inability to adapt to transfer containers of different sizes.

The buckle frame welded to the other end of the steel wire can slide in the limiting groove. When the steel wire moves, it drives the buckle frame to move and compresses the spring, allowing it to accumulate elastic potential energy. After rotating the protective cover to place the fixing block outside the support frame, the pressing frame is released, the spring elastically returns to its original position and pushes the buckle frame to slide into the slot. Through the cooperation of the two buckle frames and the slot, the protection of multiple bacterial isolation valves is achieved, ensuring that they are not damaged. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 2 , Figure 4 and Figure 5 The present invention provides an embodiment of a docking device for aseptic transfer of tissue culture seedlings, comprising a body 1, with fixing mechanisms 2 fixedly connected to both the left and right ends of the body 1, the fixing mechanisms 2 being used to seal and fix the docking container, and multiple protective mechanisms 3 fixedly connected to the front side of the outer wall of the body 1, the multiple protective mechanisms 3 being used to protect the internal structure of the body 1.

[0034] Multiple fixing mechanisms 2 each include a fixing ring 201, which is fixedly connected to the left and right ends of the body 1 respectively. A sliding groove 202 is provided in the middle of the fixing ring 201. A second fixing half ring 204 is installed at the top inside the fixing ring 201, and a first fixing half ring 203 is installed at the bottom inside the fixing ring 201. The outer walls of the first fixing half ring 203 and the outer walls of the second fixing half ring 204 are slidably connected to the inside of the sliding groove 202. A drive assembly 205 is installed at both the front and rear ends of the fixing ring 201.

[0035] Multiple drive components 205 each include a knob 2051. Multiple knobs 2051 are respectively installed at the front and rear ends of the fixed ring 201. A bidirectional threaded rod 2052 is fixedly connected to the bottom of the outer wall of the knob 2051. The front and rear ends of the first fixed half ring 203 are threadedly connected to the outer wall of the bidirectional threaded rod 2052. The front and rear ends of the second fixed half ring 204 are threadedly connected to the outer wall of the bidirectional threaded rod 2052. The outer wall of the bidirectional threaded rod 2052 is rotatably connected to the interior of the device body 1. Rubber blocks 2053 are fixedly connected to the top front and rear ends of the outer wall of the first fixed half ring 203.

[0036] Specifically, after sterilizing the device body 1, rotating the knob 2051 allows the bidirectional threaded rod 2052 welded to its bottom end to rotate inside the device body 1. The bidirectional threaded rod 2052 is threadedly connected to the first fixed half-ring 203 and the second fixed half-ring 204 respectively. When the bidirectional threaded rod 2052 rotates, it can drive the first fixed half-ring 203 and the second fixed half-ring 204 to move respectively. The slide groove 202 can restrict the rotation of the two half-rings, so the first fixed half-ring 203 and the second fixed half-ring 204 will be in the slide groove. The internal reverse movement of 202 allows the docking container to be placed inside the fixing ring 201. Then, the knob 2051 is rotated to make the first fixing half-ring 203 and the second fixing half-ring 204 move towards each other. At this time, the rubber block 2053 can fit into the second fixing half-ring 204. Both the first fixing half-ring 203 and the second fixing half-ring 204 are made of high-elastic rubber. Through the cooperation of the first fixing half-ring 203, the second fixing half-ring 204 and the rubber block 2053, the sealing and fixing of docking containers of different sizes by the device body 1 is achieved, and a sterile sealing effect is maintained continuously.

[0037] Reference Figure 3 , Figure 6 and Figure 7 Each of the multiple protection mechanisms 3 includes a support frame 301. The multiple support frames 301 are fixedly connected to the front side of the outer wall of the device body 1. A limit groove 302 is opened in the middle of the support frame 301. A fixing block 304 is installed on the outer side of the support frame 301. A slot 305 is opened at the upper and lower ends of the fixing block 304. A power component 303 is installed in the middle of the support frame 301.

[0038] The power assembly 303 includes a pressing frame 3031, which is installed in the middle of the support frame 301. The outer wall of the pressing frame 3031 is slidably connected to the inside of the support frame 301. Multiple steel wires 3032 are fixedly connected to the outer wall of the pressing frame 3031. Multiple fixed shafts 3033 are fixedly connected to the inside of the limiting groove 302. The outer wall of the steel wires 3032 is slidably connected to the outer wall of the fixed shafts 3033. A buckle frame 3034 is fixedly connected to the other end of the outer wall of the steel wires 3032. The outer wall of the buckle frame 3034 is slidably connected to the inside of the limiting groove 302. A spring 3035 is fixedly connected to the outer wall of the buckle frame 3034. The other end of the outer wall of the spring 3035 is fixedly connected to the inner wall of the limiting groove 302.

[0039] Specifically, pressing the pressing bracket 3031 causes it to slide inside the support frame 301, thereby driving the steel wire 3032 welded to it to move under the support of the fixed shaft 3033. The buckle bracket 3034 welded to the other end of the steel wire 3032 can slide in the limiting groove 302. When the steel wire 3032 moves, it can drive the buckle bracket 3034 to move and compress the spring 3035, so that it continuously accumulates elastic potential energy. After rotating the protective cover 6 to place the fixing block 304 outside the support frame 301, the pressing bracket 3031 is released. The spring 3035 uses its own elasticity to reset and pushes the buckle bracket 3034 to slide into the slot 305. Through the cooperation of the two buckle brackets 3034 and the slot 305, the multiple bacterial isolation valves 7 are protected and protected from damage.

[0040] Reference Figure 1 , Figure 2 and Figure 3 An observation window 4 is fixedly connected to the top of the device 1. The observation window 4 adopts an arc design. An operating tube 5 is fixedly connected to the front end of the outer wall of the device 1. The operating tube 5 adopts an annular design. A protective cover 6 is rotatably connected to the front end of the operating tube 5. The protective cover 6 adopts a circular design. Multiple septa membranes 7 are fixedly connected inside the operating tube 5. All multiple septa membranes 7 are installed on the rear side of the protective cover 6.

[0041] Specifically, the top of the container 1 is equipped with an observation window 4, which has an arc-shaped design to expand the field of view. The front end of the container 1 is equipped with an operating tube 5, which has a ring design and can be inserted to transfer tissue culture seedlings. The front end of the operating tube 5 has a protective cover 6, and the two are rotatably connected. Multiple antimicrobial valves 7 are fixed inside the operating tube 5 to isolate bacteria from the container 1. When the transfer tool is inserted into the container 1, the antimicrobial valves 7 can use their own elasticity to tightly fit the operating tool, improving the antimicrobial effect of the container 1. The protective cover 6 can be opened and closed flexibly to protect the antimicrobial valves 7. All components work together to facilitate observation and operation while ensuring the cleanliness of the internal environment.

[0042] Working principle: After sterilizing the device body 1, rotating the knob 2051 allows the bidirectional threaded rod 2052 welded to its bottom end to rotate inside the device body 1. The bidirectional threaded rod 2052 is threadedly connected to the first fixed half-ring 203 and the second fixed half-ring 204 respectively. When the bidirectional threaded rod 2052 rotates, it can drive the first fixed half-ring 203 and the second fixed half-ring 204 to move respectively. The sliding groove 202 restricts the rotation of the two half-rings, so the first fixed half-ring 203 and the second fixed half-ring 204 will move in the sliding groove. The inside of the groove 202 moves in the opposite direction. After the docking container is placed inside the fixing ring 201, the knob 2051 is turned so that the first fixing half ring 203 and the second fixing half ring 204 move towards each other. At this time, the rubber block 2053 can fit into the second fixing half ring 204. The first fixing half ring 203 and the second fixing half ring 204 are both made of high elastic rubber. Through the cooperation of the first fixing half ring 203, the second fixing half ring 204 and the rubber block 2053, the container body 1 can seal and fix docking containers of different sizes and continuously maintain a sterile sealing effect.

[0043] Pressing the pressing bracket 3031 causes it to slide inside the support frame 301, thereby driving the steel wire 3032 welded to it to move under the support of the fixed shaft 3033. The buckle bracket 3034 welded to the other end of the steel wire 3032 can slide in the limiting groove 302. When the steel wire 3032 moves, it can drive the buckle bracket 3034 to move and compress the spring 3035, so that it can continuously accumulate elastic potential energy. After rotating the protective cover 6 to place the fixing block 304 outside the support frame 301, the pressing bracket 3031 is released. The spring 3035 uses its own elasticity to reset and pushes the buckle bracket 3034 to slide into the slot 305. Through the cooperation of the two buckle brackets 3034 and the slot 305, the multiple bacterial isolation valves 7 are protected and protected from damage.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
