Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck technology, specifically to an energy-saving refrigerated truck door sealing structure. Background Technology

[0002] With the rapid development of the logistics industry, refrigerated transportation has become an increasingly important link in ensuring the quality and safety of perishable goods such as food and medicine. Refrigerated trucks can effectively prevent goods from deteriorating due to temperature changes during transportation, ensuring that the goods remain fresh and safe when they arrive at their destination.

[0003] However, the design and fixing methods of traditional refrigerated truck door sealing strips have certain limitations. Typically, traditional sealing strips are fixed to the door body using a single, integral design or simple adhesive bonding. While this design provides good sealing initially, its sealing performance becomes unreliable over prolonged use. Especially with frequent door opening and closing, the sealing strip is prone to loosening or damage, leading to cold air leakage and external heat intrusion. This not only affects the refrigerated truck's insulation performance but may also cause a decline in cargo quality or even spoilage. Furthermore, when the sealing strip is damaged, traditional designs often require replacing the entire sealing system. This not only increases maintenance costs but also wastes resources.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an energy-saving refrigerated truck door sealing structure to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An energy-saving refrigerated truck door sealing structure includes a door body, which is hinged to the truck body via a hinge seat. The outer side of the door body is provided with a straight sealing strip and a corner sealing strip. One side of the straight sealing strip is provided with multiple elastic pins. The door body is provided with a slot, and the pins and slots are matched. A magnetic strip is fixedly connected to one side of the straight sealing strip. The door body is provided with a groove, and a metal strip is provided inside the groove, which is matched with the magnetic strip.

[0008] Furthermore, to facilitate the splicing of straight sealing strips and corner sealing strips, mounting plates are provided on both sides of the corner sealing strip, and mounting grooves are provided on the straight sealing strip, with the mounting plates matching the mounting grooves.

[0009] Furthermore, to enhance the stability of the corner sealing strip, a corner pressure strip is provided on the outside of the corner sealing strip, and the corner pressure strip is connected to the door body by screws.

[0010] Furthermore, the mounting plate and mounting slot are provided with through holes that match the screws.

[0011] Furthermore, in order to reduce the impact on the sealing strip when the door is closed and effectively protect the sealing strip, an elastic block is fixedly connected inside the door body, and a support plate is provided inside the carriage. An abutment block is provided on one side of the support plate, and the abutment block is connected to the support plate by a spring.

[0012] Furthermore, in order to ensure that the abutment block can only move horizontally and to prevent the abutment block from shifting during the movement, a moving rod is provided inside the spring. One end of the moving rod is fixedly connected to the abutment block, and the other end is connected through the support plate.

[0013] Furthermore, to ensure the stability of the movement of the abutment block, one side of the abutment block is fixedly connected to the limiting plate, and the supporting plate is provided with a limiting groove, which is matched with the limiting groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting up straight sealing strips and corner sealing strips, when a partial sealing strip is damaged, only the damaged part needs to be replaced, instead of replacing the entire sealing system. This not only reduces maintenance costs but also improves maintenance efficiency. Furthermore, multiple elastic pins on one side of the straight sealing strip match the slots on the door body, and a magnetic strip is fixedly connected to one side of the straight sealing strip. A metal strip inside a groove on the door body matches this magnetic strip. This design not only ensures that the sealing strip is installed securely but also facilitates replacement.

[0016] (2) By fixing an elastic block inside the door and setting an abutment block and a spring inside the carriage, when the door is closed, the elastic block comes into contact with the abutment block, the spring is compressed, absorbs some of the impact energy, and then releases the energy through the rebound effect, thereby playing a buffering role, reducing the direct impact force on the sealing strip, thus protecting the sealing strip from damage and maintaining long-term effective sealing performance.

[0024] 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.

[0025] According to an embodiment of the present invention, an energy-saving refrigerated truck door sealing structure is provided.

[0026] Example 1

[0027] like Figures 1-4As shown, the energy-saving refrigerated truck door sealing structure according to an embodiment of this utility model includes a door body 1, which is hinged to the truck compartment 2 via a hinge seat 3. A straight sealing strip 4 and a corner sealing strip 5 are provided on the outer side of the door body 1. Multiple elastic locking posts 6 are provided on one side of the straight sealing strip 4. A locking groove 7 is provided on the door body 1, with the elastic locking posts 6 matching the locking groove 7. A magnetic strip 8 is fixedly connected to one side of the straight sealing strip 4. A groove 9 is provided on the door body 1, with a metal strip 10 inside the groove 9, which matches the magnetic strip 8. Mounting plates 11 are provided on both sides of the corner sealing strip 5. The mounting plate 11 is made of the same material as the straight sealing strip 4. The straight sealing strip 4 has a mounting groove 12, and the mounting plate 11 matches the mounting groove 12. The corner sealing strip 5 has a corner pressure strip 13 on its outer side, and the corner pressure strip 13 is connected to the door body 1 by screws 14. The mounting plate 11 and the mounting groove 12 have through holes 15, which match the screws 14. By passing the screws 14 through the corner pressure strip 13, the mounting plate 11, and the mounting groove 12, the straight sealing strip 4 can be further fixed while the corner sealing strip 5 is fixed, preventing the straight sealing strip 4 from falling off. With the above technical solution, when installing the straight sealing strip 4, simply align the elastic pin 6 with the slot 7 and press it firmly so that the elastic pin 6 is inserted into the slot 7. This can initially fix the straight sealing strip 4, ensuring that it will not loosen or fall off during installation. After initial fixing, a magnetic strip 8 is fixedly connected to one side of the straight sealing strip 4. The door body 1 has a groove 9, and the metal strip 10 inside the groove 9 matches the magnetic strip 8. After the elastic locking post 6 is installed in place, the magnetic strip 8 will automatically adhere to the metal strip 10, further enhancing the fixing effect of the sealing strip. The adsorption force of the magnetic strip 8 provides additional fixing force, ensuring that the straight sealing strip 4 maintains a good sealing effect under various working conditions. After the straight sealing strip 4 is installed, the corner sealing strip 5 is placed on one side of the straight sealing strip 4, the mounting plate 11 is placed inside the mounting groove 12, and the corner pressure strip 13 is placed on the outside of the corner sealing strip 5. Next, the screw 14 is passed through the through hole 15 on the corner pressure strip 13, the mounting plate 11, and the mounting groove 12 to connect with the door body 1, and the corner sealing strip 5 can be firmly fixed at the corner of the door body 1. When there is a problem with one side of the straight sealing strip 4, it is only necessary to disassemble the corner sealing strip 5 connected to the straight sealing strip 4, and then pull the straight sealing strip 4 outward to remove it. When there is a problem with the corner sealing strip 5, it is only necessary to remove the screw 14 fixed on the corner sealing strip 5 to replace the corner sealing strip 5.

[0028] like Figures 1-4As shown, an elastic block 16 is fixedly connected inside the door 1, and a support plate 17 is fixedly connected inside the carriage 2. An abutment block 18 is provided on one side of the support plate 17, matching the elastic block 16. The abutment block 18 and the support plate 17 are connected by a spring 19. A moving rod 20 is provided inside the spring 19. One end of the moving rod 20 is fixedly connected to the abutment block 18, and the other end is connected through the support plate 17. One side of the abutment block 18 is fixedly connected to a limiting plate 21. A limiting groove 22 is provided inside the support plate 17, and one end of the limiting plate 21 passes through the limiting groove 22 to further ensure the stability of the movement of the abutment block 18. With this design, when the carriage 2 door is closed, the elastic block 16 will first contact the abutment block 18. Due to the presence of the spring 19, the abutment block 18 can move freely within a certain range. When subjected to the impact force of closing the door, the spring 19 is compressed, absorbing some of the impact energy, and then releasing the energy through rebound, thereby playing a buffering role, reducing the direct impact force on the sealing strip, and thus protecting the sealing strip from damage.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, and by setting a straight sealing strip 4 and a corner sealing strip 5, when a partial sealing strip is damaged, only the damaged part needs to be replaced, without replacing the entire sealing system. This not only reduces maintenance costs but also improves repair efficiency. Furthermore, the straight sealing strip 4 has multiple elastic locking posts 6 on one side that match the locking grooves 7 on the door body 1, and a magnetic strip 8 is fixedly connected to one side of the straight sealing strip 4. The door body 1 has a groove 9, and the metal strip 10 inside matches it. This design not only ensures the sealing strip is securely installed but also facilitates replacement. Additionally, by fixing an elastic block 16 inside the door body 1, and providing an abutment block 18 and a spring 19 inside the carriage 2, when the door is closed, the elastic block 16 contacts the abutment block 18, compressing the spring 19, absorbing some of the impact energy, and then releasing the energy through rebound, thus providing a buffering effect and reducing the direct impact force on the sealing strip, protecting it from damage and maintaining long-term effective sealing performance.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
