[0026] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] As attached Figure 1 To Attachment Figure 5As shown: a local temperature control device for cold-treated plants, comprising a box body 1, wherein a vertical tube 2 is vertically arranged at each of the four corners of the box body 1, wherein the lower end of the vertical tube 2 is connected to the inner bottom end surface of the box body 1, and the upper end extends toward the top of the box body 1, and a rectangular floating plate 4 is sleeved along the outer surface of the vertical tube 2, wherein the floating plate 4 is made of sponge material, and when in use, a whole floating plate 4 can be snap-fitted and installed on the outer wall of the vertical tube 2. At the same time, a plurality of openings 41 are opened from the top to the bottom end surface of the floating plate 4, and the openings 41 are mainly used to fix EP tubes (Note: "EP tube" usually refers to a plastic centrifuge tube commonly used in laboratories, and EP tubes are usually used to store and transport liquid samples, and to perform laboratory operations such as centrifugation and PCR (polymerase chain reaction)). When the user conducts a cold stress experiment on the plant, the user can selectively put a specific part of the plant (such as rhizomes or leaves) into the EP tube, and then fix the EP tube in the opening 41.

[0028] In the above scheme, firstly, a specific part of the plant (such as rhizomes or leaves) is placed in the EP tube, and then the EP tube is fixed on the floating board 4 through the opening 41. After the fixing is completed, the user puts the external ice cubes into the box body 1 and pours water, so that a 0°C ice-water mixture can be obtained. Then the user aligns the entire floating board 4 with the vertical tube 2, and then pushes the floating board 4 downward after alignment, so that the EP tube can contact the 0°C ice water, thereby realizing the cold stress experiment on the plant.

[0029] Furthermore, a horizontal groove 5 is provided in a straight line at the middle end of the inner wall of the box body 1, and at least two horizontal bars 51 are adapted and slidably provided inside the horizontal groove 5. When in use, these horizontal bars 51 can be used to press floating ice cubes, thereby balancing the water temperature in the box body 1 and ensuring that the ice water is kept at 0°C. In addition, since the horizontal bars 51 can slide freely along the horizontal groove 5, the user can adjust the layout space in the box body 1 as needed to facilitate the quick placement of ice cubes. For example, when large ice cubes need to be put in, the sliding horizontal bars 51 can provide sufficient space, thereby speeding up the efficiency of the experiment.

[0030] Furthermore, at least one drain pipe 11 is connected from the outer side of the box body 1 to the inner bottom end, which is used to drain the ice water in the box body 1. At the same time, in order to control the drainage process, a corresponding switch valve is preset on the drain pipe 11. In this way, the user can open or close the valve as needed to control the discharge of ice water.

[0031] Furthermore, the floating board 4 is vertically provided with through holes opposite to the vertical tube 2 along the upper and lower end surfaces, and the inner diameter of these through holes is slightly smaller than the diameter of the vertical tube 2. When the vertical tube 2 passes through these through holes, the connection friction between the floating board 4 and the vertical tube 2 is increased due to the slight difference between the hole diameter and the diameter of the vertical tube 2. This design ensures that when the floating board 4 is pressed into the ice water, the friction force generated is sufficient to offset the buoyancy of the floating board 4. Therefore, even in an ice water environment, the floating board 4 can stably maintain its position, ensuring that the EP tube connected thereto continues to contact with 0°C ice water, thereby maintaining the stability of the cold stress experiment. At the same time, in order to ensure that the floating board 4 will not float up due to buoyancy in the ice water, the friction force between the floating board 4 and the vertical tube 2 is designed to be greater than the buoyancy of the floating board 4 in the ice water. Furthermore, a Velcro with a hook surface can be provided on the top surface of the top plate 251. When the bottom end surface of the floating board 4 contacts the top plate 251, the Velcro can directly hook the floating board 4 made of sponge material, thereby ensuring that the floating board 4 can be stably bonded to the top plate 251 and maintain sufficient stability. Such a design not only simplifies the connection process, but also improves the reliability of the floating board 4 in use.

[0032] like Figures 2 to 3 As shown, a movable block 22 is slidably disposed at the middle end of the vertical tube 2, and a spring 23 is disposed between the lower end of the movable block 22 and the inner bottom end surface of the vertical tube 2, and the spring 23 is used to apply an upward thrust to the movable block 22. At the same time, a lifting plate 25 is movably disposed on the outer wall surface of the vertical tube 2, and a plurality of top plates 251 are disposed at the top end surface of the lifting plate 25. When the floating board 4 is sleeved and installed on the vertical tube 2, the top plates 251 can be in contact with the left and right sides of the bottom of the floating board 4, so that when the floating board 4 is in use, it can be ejected by the top plates 251.

[0033] In addition, a vertical groove 21 is vertically provided from the outer side surface to the inner wall of the vertical tube 2, and a support block 24 is provided horizontally between the vertical groove 21 and the lifting plate 25. One end of the support block 24 is connected to the lifting plate 25, and the other end passes through the vertical groove 21 and is connected to the movable block 22, so that when in use, the lifting plate 25 can be driven by the movable block 22 and the support block 24 to move upward. For example, when the spring 23 applies an upward thrust to the movable block 22, the support block 24 will drive the lifting plate 25 to lift the floating plate 4. In this way, the lifted floating plate 4 is easier to be taken out of the box body 1.

[0034] like Figures 2 to 4As shown, a lifting rod 3 is provided through the top center of the vertical tube 2, and the lower end of the lifting rod 3 passes through the vertical tube 2 and is rotatably connected to the top end surface of the movable block 22, so that when in use, the lifting rod 3 can be driven to rotate. At the same time, the lifting rod 3 can pull the movable block 22 to move up and down, which helps to pull the floating board 4 out of the box body 1. The vertical slot 21 is connected to a plurality of slots 26 along the lower end of the inner wall. The slots 26 are connected to the outer side surface and the inner wall of the vertical pipe 2, and a block 31 is horizontally arranged at the lower end of the outer side surface of the lifting rod 3. One end of the block 31 passes through the slot 26. In this way, when in use, the lifting rod 3 can drive the block 31 to move up and down or rotate. During the movement, the block 31 can enter the vertical slot 21 or the slot 26. When entering the slot 26, the elastic force of the spring 23 cannot be released. In this way, the pressed lifting plate 25 can be stuck and limited. When the block 31 enters the vertical slot 21, the elastic force of the spring 23 is released normally, so that the elastic force can lift the lifting plate 25 and the floating plate 4.

[0035] Furthermore, the diameter of the lifting rod 3 should be smaller than the diameter of the vertical pipe 2, so that when in use, the lifting rod 3 will not hinder the installation process of the floating board 4 due to its excessively large diameter, thereby greatly improving the convenience and efficiency of installation.

[0036] Finally, it should be noted that the above embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed in the present application, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
