Technical Field

[0001] This utility model relates to the field of tissue culture equipment, and in particular to a clamping device for a tissue culture rack. Background Technology

[0002] Tissue culture racks are devices used to hold tissue culture containers during plant tissue culture, and are widely used in agriculture, forestry, horticulture, scientific research and other fields.

[0003] In the existing technology, current tissue culture racks lack effective clamping and fixing devices. Tissue culture containers are placed only by contact with the plane of the tissue culture rack, which makes it easy for tissue culture containers to come into contact with other tissue culture containers when watering, observing or moving them. This can easily cause tissue culture containers to fall off the rack after collision, resulting in low safety. Therefore, a clamping device for tissue culture racks is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping device for a tissue culture rack, which provides a device for clamping and fixing tissue culture containers, thereby preventing tissue culture containers from falling off the tissue culture rack and improving the safety of using the tissue culture rack.

[0005] To achieve the above objectives, a clamping device for a tissue culture rack is provided, comprising a base plate, a support rod fixedly connected to the upper surface of the base plate, a placement plate fixedly connected to the side surface of the support rod, a plurality of threaded rods fixedly connected to the placement plate, a mating plate movably connected to the outer surface of the threaded rods, a connecting shaft fixedly connected to the side surface of the mating plate, a movable rod rotatably connected to the outer surface of the connecting shaft, and a nut threadedly connected to the outer surface of the threaded rods.

[0027] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-6 This utility model discloses a clamping device for a tissue culture rack, comprising a base plate 1, a support rod 2 fixedly connected to the upper surface of the base plate 1, a placement plate 3 fixedly connected to the side surface of the support rod 2, a plurality of threaded rods 4 fixedly connected to the placement plate 3, a mating plate 5 movably connected to the outer surface of the threaded rods 4, a connecting shaft 6 fixedly connected to the side surface of the mating plate 5, a movable rod 7 rotatably connected to the outer surface of the connecting shaft 6, the side surface of the movable rod 7 contacting the mating plate 5, a nut 9 threadedly connected to the outer surface of the threaded rods 4, a positioning hole 8 provided on the mating plate 5, the outer surface of the threaded rods 4 movably connected to the positioning hole 8, a connecting hole 18 provided on the movable rod 7, the outer surface of the connecting shaft 6 rotatably connected to the connecting hole 18, and the number of support rods 2 is as follows. The four components are arranged in a rectangular array, and the three placement plates 3 are arranged in a linear array. It should be noted that the tissue culture rack structure is composed of the base plate 1, the support rod 2, and the placement plate 3. The remaining structure forms the clamping device. By rotating the connecting shaft 6 and unscrewing it from the threaded rod 4, the fixation between the tissue culture rack structure and the clamping device can be released, allowing the clamping device to be removed from the tissue culture rack structure for easy maintenance of each component. When it is necessary to connect the tissue culture rack structure and the clamping device, the docking plate 5 is inserted into the threaded rod 4 through the positioning hole 8 reserved on the docking plate 5, and then the connecting shaft 6 is screwed back onto the threaded rod 4 and tightened to complete the connection and fixation between the tissue culture rack structure and the clamping device.

[0029] Two corresponding movable rods 7 are fixedly connected to the same bearing plate 10. A threaded screw 11 is threadedly connected to the inner surface of the bearing plate 10. A rotating block 12 is fixedly connected to the side surface of the threaded screw 11. A connecting block 13 is rotatably connected to the inner surface of the threaded screw 11. A clamping plate 14 is fixedly connected to the side surface of the connecting block 13. A guide plate 15 is fixedly connected to the upper surface of the placement plate 3. The inner surface of the clamping plate 14 is movably connected to the guide plate 15. A sliding groove 16 is provided on the clamping plate 14. The outer surface of the guide plate 15 is movably connected to the sliding groove 16. An anti-disengagement groove 17 is provided on the threaded screw 11. The outer surface of the connecting block 13 is rotatably connected to the anti-disengagement groove 17. The side surface of the clamping plate 14 is rotatably connected to the threaded screw 11. When the threaded rod 11 contacts the guide plate 15, it should be noted that although the clamping plate 14 is inserted into the guide plate 15 through the sliding groove 16, it has a certain fixing effect. However, as long as the thrust of the threaded rod 11 is greater than the friction between the guide plate 15 and the clamping plate 14, the clamping plate 14 can be moved. Furthermore, through the action of the connecting block 13 and the anti-disengagement groove 17, not only is the connection between the clamping plate 14 and the threaded rod 11 achieved, but the rotation of the threaded rod 11, rotating block 12 and other structures will not be affected. Moreover, by rotating the rotating block 12 in the opposite direction, the threaded rod 11 can be rotated in the opposite direction, thereby allowing the clamping plate 14 to move away from the tissue culture container and release the container from fixation.

[0030] Working principle: First, the two support plates 10 are flipped, allowing the support plates 10 and other structures on them to rotate around the connecting shaft 6 on the docking plate 5. Once the flipped clamping plate 14 and support plates 10 are no longer above the placement plate 3, the support plates 10 and clamping plates 14 will not interfere with the placement of the tissue culture container. Then, the tissue culture container is placed in the space between the two guide plates 15 on the placement plate 3. Next, the two support plates 10 are flipped in the opposite direction, allowing the support plates 10 and their structures to rotate around the connecting shaft 6. When the flipping clamping plate 14 is inserted into the guide plate 15 through the groove 16, the contact area between the clamping plate 14 and the guide plate 15 is increased. The support plate 10 is fixed in place, preventing it and its structure from flipping due to non-human causes. Rotating the rotating block 12 causes the threaded screw 11 to rotate. The support plate 10 then moves the threaded screw 11 and the rotating block 12 closer to the container. During this movement, the threaded screw 11 and the rotating block 12 push the connecting block 13 and the clamping plate 14 to move. After the clamping plate 14 comes into contact with the container, the same operation is repeated on the other side. The clamping action between the two clamping plates 14 secures the container and prevents it from falling off the placement plate 3.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
