Description

Technical Field

[0001] This utility model relates to the field of cold chain logistics and warehousing technology, and in particular to a cold storage door for improving the insulation effect of cold storage. Background Technology

[0002] Cold storage doors are special doors used in refrigerated and frozen warehouses (i.e., cold storage facilities) to maintain a low internal temperature environment while preventing external heat from entering. They are an indispensable part of the cold chain logistics system and are crucial for ensuring the quality and safety of stored goods.

[0003] Existing cold storage doors typically rely on manual operation by staff to close them. However, this traditional method has two main problems. First, it cannot provide effective feedback on the closing status, meaning that staff have difficulty confirming whether the cold storage door is fully closed, which may lead to cold air leakage and temperature fluctuations. Second, existing cold storage doors only have a single insulation function, which is insufficient for modern cold chain logistics management.

[0004] To address the existing problems, there is a need for a cold storage door designed to improve the insulation performance of cold storage facilities. Utility Model Content

[0005] To overcome the shortcomings of not being able to indicate whether the cold storage door is closed and having a single insulation function, this utility model provides a cold storage door for improving the insulation effect of cold storage.

[0006] The technical solution of this utility model is as follows: a cold storage door for improving the insulation effect of cold storage, comprising mounting rods, a cold storage door, connecting blocks, a first connecting plate, sliding rods, wedge blocks, springs, electric slide rails, sliders, and sealing doors. There are two mounting rods, with the cold storage door slidably connected between them. Connecting blocks are symmetrically distributed vertically on both cold storage doors. First connecting plates are symmetrically connected to both mounting rods. Sliding rods are symmetrically connected to multiple first connecting plates. Wedge blocks are connected to the inner ends of multiple sliding rods. Multiple connecting blocks contact and engage with corresponding wedge blocks. Springs connect multiple wedge blocks to corresponding first connecting plates. Electric slide rails are symmetrically installed vertically on the front sides of both cold storage doors. Sliding sliders are slidably connected to multiple electric slide rails. Sealing doors are connected between each pair of adjacent vertical sliders, and two sealing doors on the same left and right side contact and engage.

[0007] Furthermore, it also includes a switch lock, a first temperature detector, and a first heating plate. A switch lock is installed on the front side of the cold storage door on the left side, and the first temperature detector and the first heating plate are installed on the switch lock.

[0008] Furthermore, it also includes door handles, a second temperature detector, and a second heating plate. Multiple cold storage doors are symmetrically connected with door handles, and multiple door handles are equipped with a second temperature detector and a second heating plate.

[0009] Furthermore, it also includes a second connecting plate, a movable block, a mounting plate, a third connecting plate, a fourth connecting plate, and a lead screw. The two mounting rods are symmetrically connected with second connecting plates. Each of the multiple second connecting plates has a sliding groove, and a movable block is slidably connected in each of the multiple sliding grooves. Each of the multiple movable blocks has a mounting plate installed on its rear side. Each of the multiple second connecting plates is connected with a third connecting plate, and each of the multiple second connecting plates is connected with a fourth connecting plate. Each adjacent third connecting plate and fourth connecting plate is rotatably connected with a lead screw, and each movable block is threadedly engaged with the lead screw at the corresponding position.

[0010] Furthermore, it also includes rotating rods, with rotating rods connected to the outer ends of multiple lead screws.

[0011] Furthermore, it also includes a third temperature sensor, which is symmetrically mounted on the upper mounting rod.

[0012] Furthermore, multiple mounting plates are symmetrically provided with mounting holes distributed vertically.

[0013] Furthermore, multiple connecting blocks are triangular.

[0014] The beneficial effects of this utility model are as follows: 1. By setting up connecting blocks and wedge blocks, staff can intuitively judge whether the cold storage door is closed correctly by observing whether the connecting blocks are located between the wedge blocks. This design greatly reduces the risk of cold air leakage caused by misoperation, ensures the stability of the internal environment of the cold storage, and further enhances the sealing effect of the cold storage door by having the two sealing doors contact each other and fit tightly. This double-layer sealing design not only improves the overall heat preservation performance of the cold storage, but also effectively prevents the intrusion of external heat and reduces energy consumption.

[0015] 2. The integrated first and second temperature detectors can monitor the ambient temperature inside and outside the cold storage in real time. When the ambient temperature is detected to be too low, the first and second heating plates will be automatically activated to heat the lock and door handle respectively. This not only avoids the problem of the lock not working properly due to freezing, but also ensures that the door handle is kept at a suitable temperature, making it easier for staff to operate and improving the convenience and safety of use.

[0016] 3. By rotating the rotating rod to drive the lead screw to rotate, the moving block can move along the slide groove, thereby adjusting the position of the mounting plate. This design makes the installation process more flexible and precise, can adapt to different installation needs, and ensures that each mounting plate is in the optimal position, thus guaranteeing the stability and reliability of the entire system.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: A cold storage door used to improve the insulation effect of cold storage, such as... Figures 1-7As shown, the system includes mounting rod 1, cold storage door 2, connecting block 3, first connecting plate 4, sliding rod 5, wedge block 6, spring 7, electric slide rail 8, slider 9, sealing door 10, switch lock 11, first temperature detector 12, first heating plate 13, door handle 14, second temperature detector 15, second heating plate 16, second connecting plate 17, moving block 19, mounting plate 20, third connecting plate 21, fourth connecting plate 22, lead screw 23, rotating rod 24, and third temperature detector 25. There are two mounting rods 1, and the cold storage door 2 is symmetrically slidably connected between them to seal the cold storage entrance, providing insulation and isolating the internal and external environments. Each of the two cold storage doors 2 has symmetrically connected connecting blocks 3, which, in conjunction with the wedge block 6, form a connecting block. This system is used to detect whether the cold storage door 2 is fully closed and to ensure the reliability of the closed state through mechanical limiting. Multiple connecting blocks 3 are triangular, facilitating engagement with wedge blocks 6. Two mounting rods 1 are symmetrically connected front and rear to first connecting plates 4. Multiple first connecting plates 4 are symmetrically slidably connected left and right to sliding rods 5. The inner ends of multiple sliding rods 5 are connected to wedge blocks 6. Multiple connecting blocks 3 engage with corresponding wedge blocks 6 to limit their movement. Multiple wedge blocks 6 are connected to corresponding first connecting plates 4 via springs 7. Both cold storage doors 2 have symmetrically installed electric slide rails 8 on their front sides. Multiple electric slide rails 8 are slidably connected to sliders 9. Each pair of adjacent sliders 9 is connected to a sealing door 10. (The last sentence appears to be incomplete and possibly refers to a different system.) Two sealing doors 10 on one side engage to provide an additional sealing layer. When the two sealing doors 10 engage, they further enhance the overall sealing performance of the cold storage door, preventing cold air leakage and external heat intrusion. A switch lock 11 is installed on the front side of the cold storage door 2 on the left side. A first temperature sensor 12 is installed on the switch lock 11 to monitor the temperature of the environment near the cold storage door 2 in real time. A first heating plate 13 is installed on the switch lock 11 to heat the area of ​​the switch lock 11. Multiple cold storage doors 2 are symmetrically connected with door handles 14. A second temperature sensor 15 is installed on each of the multiple door handles 14 to monitor the temperature of the environment near the cold storage door 2 in real time. A second heating plate 16 is installed on each of the multiple door handles 14 to heat the area of ​​the door handle 14 to ensure the door handle 14 is heated. To maintain usability in low-temperature environments, two mounting rods 1 are symmetrically connected to second connecting plates 17. Multiple second connecting plates 17 have grooves 18, and multiple sliding blocks 19 are slidably connected within these grooves 18. Mounting plates 20 are mounted on the rear sides of multiple sliding blocks 19. Multiple mounting plates 20 have symmetrically distributed mounting holes for easy installation. Multiple second connecting plates 17 are connected to third connecting plates 21, and multiple second connecting plates 17 are connected to fourth connecting plates 22. Each adjacent third connecting plate 21 and fourth connecting plate 22 is rotatably connected to a lead screw 23. Each sliding block 19 is threadedly engaged with a corresponding lead screw 23. Rotating rods 24 are connected to the outer ends of multiple lead screws 23.The screw 23 allows for easy rotation, and a third temperature sensor 25 is symmetrically mounted on the upper mounting rod 1 to monitor the external temperature of the cold storage in real time, helping to determine whether the overall operation of the cold storage is normal.

[0027] When installing this device, the operator first rotates the rotating rod 24. The rotation of the rotating rod 24 drives the lead screw 23 to rotate, causing the moving block 19 to move the mounting plate 20 along the slide groove 18. Once the mounting plate 20 is in the correct position, the rotating rod 24 is no longer rotated. This process is repeated to move the other three mounting plates 20 to their correct positions. After all four mounting plates 20 have been moved, the device can be installed. When using this device, if the operator needs to close the cold storage door 2, the user should push the door handles 14 on both cold storage doors 2. The cold storage door 2 will move all its components together. When the cold storage door 2 moves to a certain position, the connecting block 3 will press the wedge block 6 upwards. The wedge block 6 causes the sliding rod 5 to move outwards, compressing the spring 7. After the cold storage door 2 has moved, the connecting block 3 will no longer press the wedge block 6, and the spring 7 will reset the sliding rod 5 and the wedge block 6. The wedge block 6 will then... When the connecting block 3 is in position, both cold storage doors 2 are closed. Staff can then observe whether the connecting block 3 is between the wedge blocks 6 to determine if the cold storage doors 2 are closed. Next, the four electric sliding rails 8 are activated. The electric sliding rails 8 drive the slider 9 to move the sealing door 10 inwards. When the two sealing doors 10 come into contact, the four electric sliding rails 8 are closed. At this point, the sealing of the surface of the cold storage door 2 is complete, thus improving the insulation effect. During daily use of the cold storage door 2, staff can activate the first temperature detector 12 and the second temperature detector 15. These detectors can detect the ambient temperature. When the ambient temperature is too low, the first heating plate 13 and the second heating plate 16 can be activated. The first heating plate 13 heats the switch lock 11 to maintain a certain temperature, preventing the switch lock 11 from malfunctioning due to freezing or other issues. The second heating plate 16 heats the door handle 14 to maintain a certain temperature, making it easier for staff to touch and use.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
