Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for plant tissue culture, specifically relating to a fixing frame for tilting a plant reactor. Background Technology

[0002] In plant tissue culture, suspension (liquid) culture techniques are frequently used, where plant explants (such as callus, cotyledonary nodes, and plumules) are placed in liquid culture media or nutrient solutions. Because the explants are in a closed, sterile environment, sterile air needs to be continuously introduced into the liquid culture medium or nutrient solution to ensure air circulation and prevent anaerobic respiration, which could lead to rotting and foul odors. Simultaneously, the injection of air promotes the movement of explants within the liquid environment, improving the utilization efficiency of the liquid culture medium or nutrient solution. Furthermore, tilting the device containing the explants not only allows the plant material to aggregate more effectively, saving culture costs, but also enables the plants to move more rapidly with the help of air, further improving nutrient utilization efficiency.

[0003] However, most current fixtures can only fix objects on a horizontal surface or cannot stably fix objects at a specific tilt angle. Therefore, there is a need for a fixture that is reasonably designed, has a simple structure, and can stably place objects at a certain tilt angle. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a mounting frame for tilting a device (plant reactor) containing plant material, belonging to the technical field of auxiliary equipment for plant tissue culture. The frame includes a fixed platform and a support frame for accommodating the plant reactor. The fixed platform is equipped with a slide rail and a slot, while the support frame has a pin. The fixed platform and the support frame are connected via the slide rail / slot-pin connection. The slide rail has a curved trajectory, and the pin moves freely within the slide rail to adjust the tilt angle of the support frame and the plant reactor. When the tilt angle meets the requirements, the pin is engaged with the slot, allowing the plant reactor to be tilted and placed stably.

[0005] To address the above problems, this utility model proposes the following technical solution:

[0006] This invention provides a mounting frame for tilting a plant reactor. The mounting frame includes a fixed platform and a support frame for accommodating the plant reactor. The plant reactor refers to a container containing plants and nutrients. "Plants" refers to plant organs, plant tissues, and plant cells; "nutrients" refers to substances that maintain the normal growth / physiological activities of the plant, such as culture media (including solid and liquid forms); the container includes, but is not limited to, blue-capped bottles, petri dishes, culture flasks, and conical flasks.

[0029] The preferred embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention and do not limit it in any way. All features disclosed in the embodiments of the present invention, or all steps in all methods or processes disclosed, can be combined in any way except for mutually exclusive features and / or steps.

[0030] like Figures 1-3 As shown, the fixing frame includes a fixing platform 1 and a support frame 2. The fixing platform 1 consists of a first clamping plate 11 and a second clamping plate 12 placed horizontally, wherein the second clamping plate 12 is perpendicular to the first clamping plate 11, that is, the angle between the first clamping plate 11 and the second clamping plate 12 is equal to 90°. The second clamping plate 12 is provided with a slide rail 121 and a slot 122 that can accommodate the pin 211 on the support frame 2. The slide rail 121 is a hollow curved track with a certain curvature. It should be understood that compared with a straight track, a curved track can better meet the requirements of various inclination angles. The slots 122 are distributed on the slide rail 121, preferably evenly distributed. The pin 211 moves non-linearly along the slide rail 121 to further adjust the tilt angle of the support frame 2 and the plant reactor. When the appropriate angle is reached, the pin 211 is engaged in the slot 122 to fix the pin 211 and the support frame 2, ensuring that the tilt angle of the support frame 2 and the plant reactor remains stable and does not change over time. To reinforce the connection between the pin 211 and the slot 122, a fixing block 123 is added to the end of the pin 211 that passes through the slot 122. The fixing block 123 has a through hole in the middle to facilitate the pin 211 passing through. In use, after inserting the pin 211 into the slot 122, the fixing block 123 is tightened.

[0031] like Figures 1-4As shown, the support frame 2 consists of a first bracket 21 and a second bracket 22, which are connected at the bottom. Specifically, the bottom of the second bracket 22 is inserted into the cavity at the bottom of the first bracket 21. A pin 211 is provided on the upper side of the first bracket 21, which is used to insert into the slide rail 121 and slot 122 provided on the second clamping plate, thereby connecting the fixing platform 1 and the support frame 2 together. To allow the support frame 2 to accommodate plant reactors of different volumes, a spring 23 and a fixing block 24 are provided at the connection between the first bracket 21 and the second bracket 22. One end of the spring 23 is fitted onto the second bracket 22, and the other end abuts against the fixing block 24. Thus, when the operator pulls open the second bracket and places the plant reactor on the support frame 2, the spring 23 automatically retracts, firmly fixing the plant reactor to the support frame 2. Furthermore, to prevent the plant reactor 3 from falling out of the support frame 2 due to tilting, side wings 212 are provided on both sides of the first bracket 21.

[0032] It is important to understand that the mounting bracket described in this invention is designed based on the needs of plant tissue culture: on the one hand, tilting the container (preferably a blue-capped bottle) containing plant material and culture medium / medium allows the plant material to aggregate more effectively, and the flow of nutrient solution / medium is faster as sterile air is continuously injected into the container, further improving nutrient utilization efficiency; on the other hand, during plant tissue culture, plant growth requires sufficient light. Tilting the container (preferably a culture bottle) at different angles ensures that the plants in each container are exposed to light, thus increasing the efficiency of light and space utilization in the culture room. Furthermore, for the liquid culture of new species, it is necessary to determine the optimal culture conditions, and the tilt angle of the container containing plant material is one of the important conditions. In determining the optimal tilt angle, the containers need to be tilted at different angles, and a single variable must be strictly controlled; that is, the only difference in container placement conditions between different experimental groups is the tilt angle. Once the tilt angle is set, it cannot be changed, otherwise, the experimental results will be biased.

[0033] Based on the above requirements, the fixing frame provided by this utility model not only allows the plant reactor 3 to tilt at different angles ( Figures 5-13 It is also suitable for loading plant reactors of different specifications and types (such as blue-capped bottles, petri dishes, culture flasks, and conical flasks). The former is mainly achieved by setting up a combination of pins 211, slide rails 121, and slots 122 and a slide rail 121 with a curved track; the latter relies on a spring 23 fitted at the bottom of the second support 22. At the same time, the structure of the support frame 2 (such as the side wings 212) also ensures that the plant reactor will not fall off due to tilting.

[0034] In some methods, during the exploratory experiment, in order to strictly control variables and adjust the tilt angle, it is necessary to ensure that the position of the plant material in each plant reactor 3 is the same relative to the plant reactor. Therefore, arrow marks 31 are set on the surface of the plant reactor so that the operator can place the plant material according to the marks. The arrow marks 31 should be aligned with the top of the second support 221 to ensure that the placement of plant material between each experimental group is the same and to reduce interference from other factors during the experiment.

[0035] This embodiment provides the steps for using the fixing frame described in Embodiment 1, as follows: Pull the second bracket 22 to place the plant reactor 3 on the support frame 2. After the spring 23 retracts, the first bracket 21 and the second bracket 22 clamp the plant reactor 3. According to the required tilt degree, insert the pin 211 into the slide rail 121 and into the suitable slot 122, tighten the fixing block 123, and then stably and for a long time tilt the plant reactor 3 at a certain angle.

[0036] The application of this utility model is not limited to this. It can be expanded according to its application scope in environmental protection. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of this utility model; therefore, the scope of protection of this utility model should be determined by the scope defined in the claims.
