Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of freezer heat preservation, especially to a high strength freezer heat preservation door passage. BACKGROUND

[0002] In the traditional freezer design, the ground stake wood is installed at the freezer door passage to provide certain support for the freezer door, which can bear the weight of the freezer door and the impact force generated when the door is opened and closed, ensuring the stability and normal use of the freezer door. Since the ground may be uneven, the ground stake wood can play a leveling role. By adjusting the height of the ground stake wood, the freezer door can be kept relatively level with the surrounding ground, ensuring the sealing of the freezer door and preventing cold air leakage. When a forklift or other equipment passes through the freezer door passage, the ground stake wood can play a certain buffering role.

[0003] Today's ground stake wood is prone to water absorption and rot, affecting heat preservation and uncontrollable adjustment of the height of the foundation, making the forklift movement obstructed and affecting the handling of the goods inside the freezer. Since there is usually a certain humidity in the freezer environment, the ground stake wood is in a humid state for a long time, which can absorb water, causing the wood to rot and deteriorate. After absorbing water, the strength of the ground stake wood decreases and the wear resistance deteriorates. Under the condition of frequent passage of forklifts and other equipment, the ground is prone to depression, which brings inconvenience to the forklift passage and also affects the normal use of the freezer. Therefore, a high-strength freezer heat preservation door passage is proposed to solve the above problems. SUMMARY

[0032] Referring to Figure 1 、 Figure 2 and Figure 4The installation assembly comprises an installation plate 11, the outer part of which is fixedly connected to the outer side of the hot-dip galvanized square tube 2. The installation plate 11 is made of a solid material and can bear the weight of the nylon plate 1 and the impact force during installation. The inner part of the installation plate 11 is slidably connected with a clamping tooth 12, and fixedly connected with a sliding column 13. The outer part of the sliding column 13 is sleeved with a second telescopic spring 15, and the inner part of the installation plate 11 is provided with a sliding groove 14. One end of the second telescopic spring 15 is fixedly connected to the front end of the clamping tooth 12, and the other end is fixedly connected to the inner part of the installation plate 11. When the nylon plate 1 is installed on the top of the hot-dip galvanized square tube 2 and the polyurethane foam 3, the notch on the inner side of the nylon plate 1 is slid downward along the installation plate 11 on the outer side of the hot-dip galvanized square tube 2. At this time, the clamping tooth 12 is extruded and slides in the sliding groove 14. When it slides to the bottom, the clamping tooth 12 is pushed by the second telescopic spring 15 and is automatically fixed with the nylon plate 1, thereby completing the installation.

[0033] Working principle: When the staff needs to install a heat preservation door passage, if the height of the passage and the outside is consistent, the handle 4 can be rotated to make the rotating block 5 drive the eccentric wheel 6 to rotate. The eccentric wheel 6 will loosen the fixed block 7 from the hot-dip galvanized square tube 2 during rotation. At this time, the handle 4 can be pulled to make the sliding block 10 slide inside the hot-dip galvanized square tube 2, thereby adjusting the height to ensure that the forklift can normally enter and exit. After adjustment, the handle 4 is reversely rotated to make the rotating block 5 drive the eccentric wheel 6 to rotate. During rotation, the fixed block 7 will gradually contact the inner side of the hot-dip galvanized square tube 2, thereby being forced to slide inside the eccentric wheel 6. When the rotation is completed, the first telescopic spring 9 is compressed to the extreme by the fixed block 7, thereby stably supporting the fixed block 7, and stably fixing the position of the hot-dip galvanized square tube 2 and the sliding block 10, thereby completing the rapid height adjustment to adapt to different heights. Through the cooperation of the nylon plate 1 and the polyurethane foam 3, the consumption of cold air is greatly reduced, and the stability of the temperature inside the freezer is ensured.

[0034] When the nylon plate 1 is installed at the top of the hot-dip galvanized square tube 2 and the polyurethane foam 3, the notch on the inner side of the nylon plate 1 is slid downward along the mounting plate 11 on the outer side of the hot-dip galvanized square tube 2, at this time, the clamping tooth 12 is extruded and slides in the sliding groove 14, when sliding to the bottom, the clamping tooth 12 is pushed by the extension spring 15, and is automatically fixed with the nylon plate 1, thereby completing the installation, when disassembly is needed, the nylon plate 1 is only pulled upward, at this time, the disassembly between the hot-dip galvanized square tube 2, the polyurethane foam 3 and the nylon plate 1 is completed, through the quick installation and disassembly, the working time is reduced, the working efficiency is improved, and the problem of overall waste caused by a part of damage is avoided.
