Abstract
Description
Technical Field
[0001] This utility model relates to the field of plant cell extraction, specifically to a positioning fixture for a small plant cell extraction reactor. Background Technology
[0002] Plant cell extraction is a process that uses physical, chemical, or biological methods to separate and enrich target active ingredients from plant cell tissues. It is widely used in pharmaceutical research and development, health food, cosmetic raw material preparation, and biochemical fields.
[0003] Small-scale reaction vessels are key equipment for laboratory research on plant cell extraction. They are mainly used for small-batch, multi-parameter extraction process optimization experiments and sample preparation. Small-scale reaction vessels support multiple parallel experiments and can quickly compare the component yields under different solvent ratios, extraction times, and temperature conditions, providing reliable process data support for industrial-scale production. They are an indispensable core device in the research and development stage of plant cell extraction technology.
[0004] In the process of extracting plant cells using small laboratory reactors, the high-speed rotation of the agitator easily causes eccentric vibration of the reactor body. Furthermore, the small weight and small contact area of the base of these reactors make them prone to slippage or even tipping. Currently, laboratories commonly stabilize the reactors manually, increasing the labor intensity and costs for researchers. Moreover, manual handling is insufficient to effectively ensure reactor stability, affecting both the stability of the extraction system and the accuracy of experimental data, and significantly reducing experimental efficiency. Therefore, it is necessary to invent a positioning fixture for small plant cell extraction reactors to solve these problems. Utility Model Content
[0005] The purpose of this invention is to provide a positioning fixture for a small plant cell extraction reactor. By setting four pressure blocks, the reactor can be fixed inside the fixture seat by radial clamping, eliminating the need to manually hold the reactor to maintain its stability. This solves the problem of increased labor intensity and labor costs caused by manually holding the reactor.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning clamp for a small plant cell extraction reactor, comprising: A clamping base, wherein a sliding groove is formed on the inner wall of the clamping base; A radial positioning mechanism includes a pressure block slidably connected to the inner wall of a groove, a collar slidably connected to the outer wall of a fixture seat, a connecting rod hinged to the inner wall of the collar, a threaded sleeve fixedly connected to the outer wall of the fixture seat, a threaded rod threadedly connected to the inner wall of the threaded sleeve, and a knob fixedly connected to the top end of the threaded rod. The mounting block is fixedly connected to the outer wall of the clamp seat, and the inner wall of the mounting block has mounting holes.
[0007] Preferably, a column is fixedly connected to the inner wall of the clamp seat, and a suction cup is fixedly connected to the top of the column.
[0008] Preferably, the side of the pressure block away from the collar has an arc-shaped structure and is fixedly connected with an anti-slip pad.
[0009] Preferably, the column and the clamp seat are coaxial.
[0010] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes a radial positioning mechanism on the inner wall of the clamping seat to clamp the reactor within the clamping seat in a circumferential positioning manner, preventing radial displacement of the reactor and ensuring its stability during use. The reactor no longer needs to be held by hand, allowing researchers to perform other experimental operations during the reaction process, thus improving the convenience and efficiency of plant cell extraction experiments. Simultaneously, the suction cups and columns apply a downward pulling force to the reactor, thereby axially positioning it and further enhancing its stability. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0015] This utility model provides, for example Figure 1 - Figure 3 The small plant cell extraction reactor positioning fixture shown includes a fixture base 1, a radial positioning mechanism 3, and a mounting block 6. The inner wall of the clamp base 1 is provided with a sliding groove 2, which can provide guidance for the pressure block 31 and make the pressure block 31 slide stably. like Figure 2 - Figure 3 As shown, the radial positioning mechanism 3 includes a pressure block 31, which is slidably connected to the inner wall of the slide groove 2. By using four pressure blocks 31 to slide synchronously on the inner wall of the slide groove 2, the reactor 8 can be clamped inside the fixture seat 1, thus ensuring the stability of the reactor 8. A collar 32 is slidably connected to the outer wall of the fixture seat 1. A connecting rod 33 is hinged to the inner wall of the collar 32. The end of the connecting rod 33 away from the collar 32 is hinged to the inner wall of the pressure block 31. While the collar 32 slides on the outer wall of the fixture seat 1, it can drive the pressure block 31 to slide on the inner wall of the slide groove 2 in conjunction with the connecting rod 33. A threaded sleeve 34 is fixedly connected to the outer wall of the fixture seat 1. A threaded rod 35 is threadedly connected to the inner wall of the threaded sleeve 34. A knob 36 is fixedly connected to the top of the threaded rod 35. By rotating the threaded rod 35 through the knob 36, the threaded rod 35 can be driven to move axially on the inner wall of the threaded sleeve 34. like Figure 2 - Figure 3 As shown, the mounting block 6 is fixedly connected to the outer wall of the fixture seat 1. The inner wall of the mounting block 6 is provided with mounting holes 7. By passing the bolt through the mounting holes 7 and locking it on the test bench, the fixture seat 1 can be fixed on the laboratory table.
[0016] like Figure 1 As shown, a column 4 is fixedly connected to the inner wall of the clamp seat 1. The column 4 and the clamp seat 1 are coaxial. A suction cup 5 is fixedly connected to the top of the column 4. When the reactor 8 is inserted into the interior of the clamp seat 1, the suction cup 5 will adhere to the bottom of the reactor 8. The adsorption of the suction cup 5, combined with the connection of the column 4, can limit the axial movement of the reactor 8, further improving the stability of the reactor 8 during use.
[0017] like Figure 3 As shown, the side of the pressure block 31 away from the collar 32 has an arc-shaped structure and is fixedly connected with an anti-slip pad 37. The arc-shaped structure of the side wall of the pressure block 31 can better fit the outer wall of the cylindrical reactor 8, and the excellent friction of the anti-slip pad 37 can improve the stability of the pressure block 31 in holding the reactor 8.
[0018] The working principle of this practical application is as follows: When using the reactor 8, insert the reactor 8 into the fixture seat 1, and then push the collar 32 downwards. This causes the collar 32 to push the connecting rod 33, which in turn pushes the pressure block 31. The pressure block 31 slides along the inner wall of the slide groove 2 and gradually moves away from the collar 32. Simultaneously, the pressure block 31 causes the anti-slip pad 37 to gradually approach the reactor 8 until the pressure block 31 and the anti-slip pad 37 are pressed against the outer wall of the reactor 8. Then, rotate the threaded rod 35 using the knob 36. The threaded engagement between the threaded rod 35 and the threaded sleeve 34 allows the threaded rod 35 to move axially while rotating, until the thread... The bottom end of the rod 35 is pressed against the top of the collar 32. At this time, the top of the collar 32 can be limited by the threaded rod 35, so that the collar 32 can no longer slide upward. Since the pressure block 31 drives the anti-slip pad 37 to press against the outer wall of the reactor 8, the collar 32 can no longer slide downward to push the pressure block 31 with the connecting rod 33. In this way, the collar 32 can be limited to the outer wall of the clamp seat 1. At the same time, the four pressure blocks 31 can be pressed against the outer wall of the reactor 8 to clamp the reactor 8 to the inner wall of the clamp seat 1. In this way, the reactor 8 can be radially limited to prevent mechanical vibration from causing the reactor 8 to shift or tip over.
[0019] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
