Description

Technical Field

[0001] This utility model relates to the field of refrigerated transport equipment technology, and in particular to a multi-temperature zone refrigerated truck structure. Background Technology

[0002] In cold chain logistics transportation, it is often necessary to transport multiple goods with different temperature requirements at the same time. For example, fresh vegetables and fruits need to be transported in the preservation temperature range of 0-5℃, while frozen meat and seafood need to be stored in the freezing temperature range below -18℃. Traditional single-temperature refrigerated trucks cannot meet the needs of transporting multiple goods at the same time. If multiple refrigerated trucks with different temperature zones are used for separate transportation, it will greatly increase transportation costs and waste resources.

[0003] While some existing multi-temperature zone refrigerated trucks have achieved multi-temperature zone division, they suffer from the following problems: The current sealing method used in refrigerated trucks involves installing strip-shaped A sealing strips and plate-shaped B sealing strips on both side doors. When the door is closed, the B sealing strip abuts against the A sealing strip, and the subsequent temperature and air pressure inside the truck cause the sealing strips to contract inward to achieve a sealing effect. However, this structure results in excessive internal pressure, requiring a great deal of force to open the truck door, and aligning the A and B sealing strips when closing the door, which delays loading and unloading time. Therefore, these problems need to be addressed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-temperature zone refrigerated truck structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-temperature zone refrigerated truck body structure, including a body, a door hinged to the front end of the body, a sealing mechanism installed inside the door, two adjusting rods installed inside the body, and a folding mechanism installed on the adjusting rods.

[0006] Preferably, a lock plate is hinged to the door, a lock ring is hinged to the lock plate, a push ring is hinged to one end of the lock ring, an L-shaped hook is fixed to one side of the compartment, and one end of the lock ring is engaged with the hook.

[0007] Preferably, the sealing mechanism includes a valve rotatably mounted on the door and a sealing layer mounted on the inner side of the door, wherein a threaded rod is fixedly connected to the valve, and the sealing layer is threadedly connected to the threaded rod.

[0008] Preferably, four guide rods are installed on the inside of the door, and the sealing layer is inserted into the guide rods.

[0009] Preferably, the folding mechanism includes two sets of adjusting rings sleeved on the adjusting rods and a placement plate disposed inside the two adjusting rods. The adjusting rods are provided with a plurality of adjusting holes at equal intervals, and the adjusting rings are provided with positioning holes that match the adjusting holes. A limiting block is inserted into one side of the adjusting ring, one end of the limiting block is fixedly connected to the limiting ring, and the other end of the limiting ring is fixedly connected to the placement plate.

[0010] Preferably, threaded blocks are fixed to both ends of the placement plate, the threaded blocks pass through the limiting ring, and a threaded cylinder is threadedly connected to the threaded blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By rotating the valve, this utility model facilitates the movement of the sealing layer into the compartment, thereby sealing the interior of the compartment. As the sealing layer moves into the compartment, it compresses the air inside the compartment, thus creating suction and enhancing its sealing performance. To open, only the threaded rod needs to be rotated, which reduces the force required to open the sealing layer, simplifying the opening and closing of the compartment door, saving unloading time, and ultimately solving the problem that existing compartment doors are inconvenient to open, affecting unloading time.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5 This utility model discloses a multi-temperature zone refrigerated truck body structure, including a body 1 for refrigerating transported objects; a door 2 hinged to the front end of the body 1 for sealing the interior of the body 1; a sealing mechanism installed inside the door 2; two adjusting rods 3 installed inside the body 1 for adjusting the height of the placement plate 12; a folding mechanism installed on the adjusting rods 3; a locking plate 4 hinged to the door 2 for installing a locking ring 5; a locking ring 5 hinged to the locking plate 4 for securing the door 2 to the body 1 with a hook; and a push ring 6 hinged to one end of the locking ring 5. The push ring 6 facilitates the locking ring 5 to release the lock between the compartment 1 and the door 2; an L-shaped hook is fixedly connected to one side of the compartment 1, and one end of the locking ring 5 is engaged with the hook; the sealing mechanism includes a valve 8 rotatably installed on the door 2 and a sealing layer 7 installed on the inner side of the door 2; the valve 8 facilitates the control of the sealing layer 7 to seal the compartment 1; a threaded rod 9 is fixedly connected to the valve 8, which facilitates the movement of the sealing layer 7; the sealing layer 7 is threadedly connected to the threaded rod 9; four guide rods 10 are installed on the inner side of the door 2, which facilitate the movement of the sealing layer 7; the sealing layer 7 is inserted into the guide rods 10.

[0021] In this utility model, the folding mechanism includes two sets of adjusting rings 11 sleeved on the adjusting rods 3 and a placement plate 12 disposed inside the two adjusting rods 3. The adjusting rings 11 facilitate the insertion and installation of the placement plate 12. Multiple adjusting holes 13 are equidistantly opened on the adjusting rods 3, which facilitate the adjustment of the height of the placement plate 12. The adjusting rings 11 are provided with positioning holes that match the adjusting holes 13. A limiting block 15 is inserted into one side of the adjusting rings 11, which facilitates the adjustment of the tilt angle of the placement plate 12. One end of the limiting block 15 is fixedly connected to a limiting ring 14, and the other end of the limiting ring 14 is fixedly connected to the placement plate 12. Threaded blocks are fixedly connected to both ends of the placement plate 12. The threaded blocks pass through the limiting ring 14, and a threaded cylinder 16 is threadedly connected to the threaded blocks.

[0022] Working principle: When using this utility model, first turn valve 8, which drives threaded rod 9 to rotate, thereby moving sealing layer 7. When sealing layer 7 returns to door 2, body 1 is unsealed. Then push push ring 6. Since there is a certain gap between door 2 and body 1, push ring 6 can be pushed to move locking ring 5, thereby releasing the lock between locking ring 5 and hook. At this time, door 2 can be opened and body 1 can be entered. Turn threaded cylinder 16 to pull out limit block 15, turn placement plate 12 to place placement plate 12 longitudinally, and finally adjust the height of adjusting ring 11 through adjusting hole 13 to store placement plate 12. Finally, close door 2 and turn valve 8 to seal body 1.
