Description

Technical Field

[0001] This utility model relates to the field of plant cold resistance testing technology, specifically a device for testing the cold resistance of honeysuckle tree branches. Background Technology

[0002] Honeysuckle berry is a deciduous shrub belonging to the genus *Lonicera* in the family Caprifoliaceae. Therefore, its branches exhibit some typical characteristics of Caprifoliaceae plants. Young branches are typically yellowish-green, greenish-brown, or slightly purplish, with a relatively smooth surface. As the branches age, they gradually turn grayish-white or grayish-brown, and the bark may develop slight longitudinal cracks or peeling.

[0003] Research on plant cold resistance is a crucial component of plant stress resistance research. Studying plant morphology, structure, and physiological and biochemical characteristics, and accurately identifying and testing their cold resistance, provides fundamental data and references for further metabolomics, hybridization breeding, and transgenic cultivation of cold-resistant varieties. This is of great significance for species conservation and the breeding of superior varieties. The main principle of detecting the cold resistance of plant branches is as follows: detecting the heat released by the plant branch before it dies from low temperatures causes a temperature difference across a semiconductor cooling device, which in turn generates a voltage difference at the two output terminals of the semiconductor cooling device based on the Peltier effect.

[0004] Existing patent CN222379660U proposes a plant branch cold resistance performance testing device, including a placement rack, in which several test subjects are equidistantly slidably placed. Each test subject includes a fixedly connected support frame plate and a top cover plate. The upper surface of the support frame plate is provided with equidistant limiting grooves. This invention avoids the problem of plant branches being damaged or broken due to the conflict between the cold air during cold resistance performance testing and the tightness of the sliding parts.

[0005] However, the testing device still has some defects. During use, the sliding plate needs to be inserted into the first sliding groove. However, the friction is large when manually pushing the insertion, which makes the installation inconvenient and makes it difficult to quickly limit the sliding plate. At the same time, the thermoelectric cooler only dissipates heat through the multi-hole ventilation plate, resulting in poor heat dissipation effect, which affects the cooling effect of the thermoelectric cooler and makes the cold resistance test result poor.

[0006] Based on this, a device for testing the cold resistance of honeysuckle tree branches is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0007] The purpose of this invention is to provide a device for testing the cold resistance of honeysuckle tree branches, so as to solve the problems of insufficient convenience and poor heat dissipation in the prior art.

The limiting hole 12 is used in conjunction with the limiting component to limit the sliding component. The ventilation component promotes air circulation, and the heat dissipation component is used for heat dissipation. The setting of the bottom roller 21 inside the sliding plate 2 improves the smoothness of the sliding plate 2 sliding inside the sliding groove 11. The support component supports the tree branch.

A diverter plate 15 is installed on one side of the air outlet duct 14, and an air outlet plate 16 is installed on one side of the diverter plate 15. The air outlet plate 16 is installed at the air outlet end of the blower 17. By operating the blower 17, outside air is drawn in and sent to the diverter plate 15 through the air outlet plate 16. The air is then diverted by the diverter plate 15 and sent to the three air outlet ducts 14. The air is then sent to the ventilation frame 33 through the air outlet ducts 14.

[0027] In one embodiment, such as Figure 1 and Figure 3 As shown, the limiting component includes an insertion block 23, which is slidably connected inside the connecting frame 22. Two springs 24 are installed on both sides of the bottom of the insertion block 23, and a linkage rod 25 is installed in the middle of the insertion block 23. The linkage rod 25 supports the two insertion blocks 23. By pressing the linkage rod 25, the two insertion blocks 23 slide downward inside the connecting frame 22, causing the springs 24 to contract.

[0028] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the support assembly includes a support plate 3, which is installed in the middle of the sliding plate 2. A hinge 31 is installed on one side of the top of the support plate 3, and a top cover 32 is installed on one side of the hinge 31. A ventilation frame 33 is installed at the bottom of the support plate 3. The top cover 32 is flipped open or closed by the hinge 31, and the air is guided by the ventilation frame 33.

[0029] In one embodiment, such as Figure 1 and Figure 4 As shown, a heat dissipation component is installed inside the support plate 3 to dissipate heat.

[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the heat dissipation assembly includes a thermoelectric cooler 34, which is installed inside the support plate 3. Heat dissipation fins 35 are installed on the bottom of the thermoelectric cooler 34 to dissipate heat from the heat-generating end of the thermoelectric cooler 34.

[0031] In one embodiment, such as Figure 1 and Figure 4 As shown, two clamping components are installed on the top two sides of the support plate 3 to wrap the tree branches.

[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, the clamping assembly includes a first rubber plate 36, which is installed on both sides of the top of the support plate 3. A connecting block 37 is installed on one side of the first rubber plate 36, and a support block 38 is installed on the other side of the first rubber plate 36. A second rubber plate 39 is installed on the top of one side of the support block 38, and an insertion plate 310 is installed on one side of the second rubber plate 39. The insertion plate 310 and the connecting block 37 are fitted together. The first rubber plate 36 supports the bottom of the branch, the second rubber plate 39 supports and wraps the top of the branch, and the insertion plate 310 and the connecting block 37 are fitted together for fixation.

[0033] The above embodiment discloses a device for testing the cold resistance performance of honeysuckle berry branches. The branch is placed on top of a support plate 3, with two first rubber plates 36 supporting the bottom of the branch. A second rubber plate 39 on one side of a support block 38 wraps around the top of the branch. An insertion plate 310 is inserted into a connecting block 37 to support the second rubber plate 39, facilitating the wrapping and clamping of the branch. The hinge 31 flips, causing the top cover 32 to flip and close, preventing condensation from contacting outside air during the cold resistance test and thus improving the device's practicality. Sliding plates 2 on both sides of the support plate 3 are inserted into sliding grooves 11. The rotation of the bottom rollers 21 inside the sliding plates 2 improves the smoothness of the sliding plates 2 within the sliding grooves 11. Pressing the linkage rod 25 causes the two insertion blocks 23 to... The connecting frame 22 slides downwards, causing the spring 24 to contract, so that the connecting frame 22 can be inserted into the sliding groove 11. After insertion, the linkage rod 25 is released, and the automatic rebound of the spring 24 pushes the insertion block 23 to move upwards inside the connecting frame 22 and insert into the limiting hole 12 for limiting, which improves the stability and convenience of the device. The operation of the semiconductor cooling chip 34 cools the tree branches. The heat dissipation fins 35 dissipate heat from the heating end of the semiconductor cooling chip 34. The operation of the blower 17 draws in outside air and sends it into the diverter plate 15 through the air outlet plate 16. The diverter plate 15 divides the air and sends it into the three air outlet plates 16. The air outlet plates 16 send the air into the ventilation frame 33, thereby quickly dissipating heat from the heat dissipation fins 35, improving the heat dissipation and cooling effect of the device.
