Description

Technical Field

[0001] This utility model belongs to the field of freeze dryer technology, and in particular relates to a modular sample loading platform for freeze dryers. Background Technology

[0002] Freeze dryers, as equipment that uses vacuum freeze-drying technology to dry materials, are widely used in many fields such as medicine, biological products, and food. Their working principle is based on the three states of water. Under high vacuum, the water in the pre-frozen material is directly sublimated from solid to gas, thereby achieving the drying of the material. During the freeze-drying process, the sample loading platform plays a crucial role in supporting and placing the sample. Currently, most sample loading platforms used in freeze dryers on the market adopt a relatively fixed structural design, making it difficult to flexibly and conveniently adjust the relative distance between platforms during actual use. This results in the inability to place tall sample containers smoothly due to the small platform spacing; or when placing multiple smaller sample containers, the inability to reduce the platform spacing leads to wasted space, failure to fully utilize the internal space of the freeze dryer, reduced working efficiency and loading capacity, and consequently affects the cost-effectiveness and product quality of the entire freeze-drying production process. Utility Model Content

[0003] The purpose of this invention is to provide a modular sample loading platform for a freeze dryer. By incorporating an adjustment mechanism, specifically when the relative distance between the loading platforms needs to be adjusted, the operator rotates a knob to rotate a threaded rod. The four threaded sections on the outer wall of the threaded rod engage with four internal threaded blocks, causing the internal threaded blocks to slide along mounting ring one and three mounting rings two. Simultaneously, a guide rod and guide blocks ensure smooth movement. Furthermore, mounting ring one and the three mounting rings two respectively move the four loading platforms, thus achieving precise adjustment of the relative distance between the four loading platforms. This not only adapts to the loading requirements of samples of different sizes but also optimizes the airflow circulation path within the freeze dryer, improving freeze-drying efficiency and preventing uneven sample heating or excessively long freeze-drying times due to improper spacing. It solves the problem of difficulty in flexibly and conveniently adjusting the relative distance between platforms in practical use.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model discloses a modular sample loading platform for a freeze dryer, comprising a base plate, two support frames fixedly connected to the outer wall of the base plate, a mounting ring slidably connected between the two support frames, three mounting rings slidably connected between the two support frames, a handle fixedly connected to the top of the mounting ring 1, and a loading platform slidably connected to the inner walls of the mounting ring 1 and the three mounting rings 2, and further comprising: An adjustment mechanism, disposed inside two support frames, is used to adjust the relative distance between the four loading platforms; and The installation mechanism is provided in four sets, and the four sets of installation mechanisms are respectively located inside the first installation ring and the three second installation rings; The four loading platforms are different loading platform modules, and are respectively connected to the first mounting ring and the three second mounting rings through the installation mechanism.

[0005] Furthermore, the adjustment mechanism includes an adjustment component disposed inside the support frame on the left side, the adjustment component being used to adjust the spatial distance between the four loading platforms; and A guide component is disposed inside the support frame on the right side, and the guide component is used to guide the four loading platforms when adjusting the distance.

[0006] Furthermore, the mounting mechanism includes a connecting component disposed inside the second mounting ring, the connecting component being used to connect the second mounting ring to the loading platform; and A fixing component is disposed outside the mounting ring two, and the fixing component is used for quick disassembly and installation of the loading platform.

[0007] Furthermore, the adjustment assembly includes a threaded rod rotatably connected to the bottom wall inside the support frame on the left side. The top end of the threaded rod extends to the outside of the support frame on the left side. The outer wall of the threaded rod is threaded with four internal threaded blocks. The right sides of the four internal threaded blocks extend to the outside of the support frame on the left side and are slidably connected to the support frame on the left side. The right sides of the four internal threaded blocks are respectively fixedly connected to the outer walls of mounting ring one and three mounting ring two. A knob is fixedly connected to the top end of the threaded rod. The screw rod is rotated by a knob, which in turn moves four internal thread blocks, which in turn move mounting ring one and three mounting ring two.

[0008] Furthermore, the guide assembly includes a guide rod fixedly connected inside the support frame located on the right side, and four guide blocks are slidably connected to the outer wall of the guide rod. The left sides of the four guide blocks extend to the outside of the support frame located on the right side and are slidably connected to the support frame located on the right side. The left sides of the four guide blocks are respectively fixedly connected to mounting ring one and three mounting ring two. The guide rod is fixedly connected to the support frame on the right side by welding, and the four guide blocks are all adapted to the inner wall of the support frame on the right side.

[0009] Furthermore, the connecting assembly includes two protrusions fixedly connected to the outer wall of the loading platform, and the inner wall of the second mounting ring has two sliding grooves. Among them, the first slide is a vertical slide, and the second slide is a horizontal annular slide.

[0010] Furthermore, the fixing component includes two slide grooves three respectively opened on the side of the two protrusions away from the loading platform. Both slide grooves three extend into the interior of the loading platform. Springs are fixedly connected to the inner bottom walls of both slide grooves three. Limiting blocks are fixedly connected to the ends of the two springs that are far apart from each other. Two limiting grooves are opened on the inner wall of the mounting ring two. The side of the two limiting blocks away from the corresponding springs extends into the interior of the corresponding limiting grooves and is slidably connected to the corresponding limiting grooves. One side of the limiting block is designed to be arc-shaped, and the side of the limiting groove that contacts the arc-shaped surface of the limiting block is also designed to be arc-shaped.

[0011] This utility model has the following beneficial effects: 1. By setting up an adjustment mechanism, specifically when it is necessary to adjust the relative distance between the loading platforms, the operator turns the knob to drive the threaded rod to rotate. Utilizing the cooperation of the four threaded sections on the outer wall of the threaded rod with the four internal threaded blocks, the internal threaded blocks drive the first mounting ring and three second mounting rings to slide. At the same time, the guide rod and guide block ensure smooth movement. Then, the first mounting ring and three second mounting rings drive the four loading platforms to move respectively, thereby achieving precise adjustment of the relative distance between the four loading platforms. This can not only adapt to the loading needs of samples of different sizes, but also optimize the airflow circulation path in the freeze dryer, improve freeze drying efficiency, and avoid uneven heating of samples or excessively long freeze drying time due to improper spacing.

[0012] 2. By setting up an installation mechanism, specifically, the protrusion of the loading platform is aligned with the vertical groove one on the inner wall of the second mounting ring and inserted into the horizontal annular groove two. During this process, the limiting block inside the protrusion is compressed by the spring. Then, the loading platform is rotated 90 degrees to align the protrusion with the limiting groove. The spring returns to its original position and pushes the limiting block into the limiting groove, achieving a stable connection. When disassembling, the loading platform is rotated in the opposite direction. The protrusion is compressed by the spring and disengages from the second groove. After the protrusion returns to the position of the first groove, it is pulled upward. This structure eliminates the need to press the limiting block. The loading platform can be quickly disassembled and assembled by rotating and cooperating with the groove. This facilitates the replacement of different modules to adapt to various samples, shortens the equipment adjustment time, and improves the equipment's versatility and ease of operation.

[0018] Please see Figure 1-5 As shown, this utility model is a modular sample loading platform for a freeze dryer, including a base plate 1.

Among them, the threaded rod 211 is rotatably connected to the support frame 11 located on the left side through a bearing, and the four internal threaded blocks 212 are all adapted to the inner wall of the support frame 11 located on the left side.

[0022] The guide assembly 22 includes a guide rod 221 fixedly connected inside the support frame 11 on the right side.

[0023] The connecting component 31 includes two protrusions 311 fixedly connected to the outer wall of the loading platform 15, and two sliding grooves 312 are opened on the inner wall of the mounting ring 13. Among them, the two slides 312 and 313 are adapted to each other.

[0024] The fixing component 32 includes two slide grooves 321 respectively opened on the side of the two protrusions 311 away from the loading platform 15. Both slide grooves 321 extend into the interior of the loading platform 15. Springs 322 are fixedly connected to the bottom wall of the interior of the two slide grooves 321. Limiting blocks 323 are fixedly connected to the ends of the two springs 322 that are away from each other. Two limiting grooves 324 are opened on the inner wall of the mounting ring 13. The side of the two limiting blocks 323 away from the corresponding springs 322 extends into the interior of the corresponding limiting grooves 324 and slides in connection with the corresponding limiting grooves 324. The loading platform 15 is connected to the mounting ring 13 by the engagement of the limiting block 323 and the limiting groove 324.

[0025] A specific application of this embodiment is as follows: When using this device, if it is necessary to adjust the distance between the four loading platforms 15, the operator rotates the knob 213, causing the threaded rod 211 to rotate within the left support frame 11. Since the outer wall of the threaded rod 211 has four identical threaded lines evenly distributed axially, and each threadedly engages with one of the four internal threaded blocks 212, when the threaded rod 211 rotates, the four internal threaded blocks 212 move synchronously along the axial direction of the threaded rod 211. As the internal threaded blocks 212 move, they cause the mounting ring 12 and three mounting rings 23 fixedly connected to them to slide between the two support frames 11. Simultaneously... The guide rod 221 inside the right support frame 11 serves as a guide. The four guide blocks 222 are fixedly connected to the mounting ring 12 and the mounting ring 23 and slide along the guide rod 221 to ensure that the mounting ring 12 and the mounting ring 23 move smoothly without shifting or tilting. This allows for precise adjustment of the relative distance between the four loading platforms 15 to adapt to the loading requirements of samples of different sizes and to optimize the airflow circulation path within the freeze dryer. The four loading platforms 15 are composed of different carrier platform modules, from top to bottom: a tray carrier platform module, a vial fixing carrier platform module, and two irregular sample adaptation carrier platform modules.

[0026] When installing the loading platform 15, align the two protrusions 311 on the loading platform 15 with the two vertical grooves 312 on the inner wall of the mounting ring 13. Insert the protrusions 311 into the grooves 312 and slide them downwards, allowing the protrusions 311 to slide into the horizontal annular groove 313. During this process, the limiting block 323 inside the protrusion 311 is squeezed by the inner wall of the mounting ring 13, and the compression spring 322 contracts into the groove 321. Then, rotate the loading platform 15 ninety degrees so that the protrusions 311 are aligned with the limiting groove 324. When the protrusions 311 slide to the corresponding position of the limiting groove 324, the spring 322 returns to its original position, pushing the limiting block 323 into the limiting groove 324. Through the interaction between the limiting block 323 and the limiting groove 324, the loading platform 15 is then rotated ninety degrees to align the protrusions 311 with the limiting groove 324. The arc-shaped surface of 24 ensures a stable connection between the loading platform 15 and the mounting ring 2 13. During disassembly, simply rotate the loading platform 15 in the reverse direction. The arc-shaped surface of the protrusion 311 and the slide 1 312 are positioned close to each other, causing the protrusion 311 to be compressed by the spring 322 and disengage from the slide 1 312 and retract into the slide 3 321. Then, when the protrusion 311 rotates to the position of the slide 1 312, the loading platform 15 can be disassembled upwards. Pressing the limiting block 323 causes it to retract into the slide 3 321, allowing the protrusion 311 to be pulled out from the slide 2 313 and the slide 1 312, thus completing the quick disassembly of the loading platform 15. This facilitates the replacement of different types of loading platform modules to adapt to diverse samples.
