[0002] The main function of refrigerated trucks is to maintain a low-temperature environment for frozen or fresh goods, ensuring that the goods maintain ideal temperature conditions during transportation. Through their special refrigeration equipment and insulation materials, refrigerated trucks provide a suitable low-temperature environment for different types of goods, thereby extending the shelf life of the goods and maintaining their freshness, such as frozen meat, seafood, bean products, and quick-frozen foods, ensuring that these foods will not thaw or spoil during transportation.
[0003] When using existing refrigerated trucks, their function is to freeze or preserve goods. Existing refrigerated trucks are sealed by doors, but gaps may appear between the truck body and the doors, causing cold air to leak out and increasing power consumption. Utility Model Content
[0004] The purpose of this utility model is to provide a refrigerated truck with high sealing performance to solve the problem mentioned in the background art that existing refrigerated trucks are sealed by doors, but gaps will appear between the truck body and the doors, causing cold air to leak out and increasing power consumption.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerated truck with high sealing performance, comprising:
[0006] The refrigerated truck body includes a cargo compartment with doors connected to both sides of the compartment.
[0007] The inner surface of the carriage is connected to both sides of a sealing structure. The sealing structure includes a positioning block, one end of which is connected to a fixing screw. A sealing plate is sleeved on the outer wall of the fixing screw. A nut is rotatably connected to the outer surface of one end of the fixing screw. A rubber pad is provided on the surface of the sealing plate.
[0008] Preferably, the inner surface of the sealing plate is provided with positioning grooves on both sides, and the positioning block is inserted into the positioning grooves provided in the sealing plate.
[0009] Preferably, a through hole is provided on one side of the inner wall of the positioning groove of the sealing plate, and the fixing screw is inserted into the through hole of the sealing plate.
[0010] Preferably, the fixing screw and the nut are rotatably connected by threads, and the rubber pad is used to separate and buffer the sealing plate and the closed door.
[0011] Preferably, the sealing plate has an adjustment mechanism inside both sides. The adjustment mechanism includes a rubber ring, a guide rod is inserted inside the rubber ring, a limit ring is sleeved on the outer wall of one end of the guide rod, and a sealing ring is connected to the surface of one end of the limit ring.
[0012] Preferably, the bottom of the compartment door has grooves on both sides, the grooves of the compartment door are for the passage of guide rods, the bottom of the sealing plate has through grooves on both sides, and the rubber ring is disposed inside the through grooves of the sealing plate.
[0013] Preferably, the sealing plate and the guide rod are in flexible contact using a rubber ring, and the limiting ring is filled between the rubber ring and the sealing ring for buffering.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. By inserting the sealing plate into the interior of the carriage, inserting the fixing screw into the through hole of the sealing plate, and inserting the positioning block into the positioning groove of the sealing plate, the carriage and the sealing plate are positioned. Then, the nut is rotated and connected to the outer surface of one end of the fixing screw to limit the sealing plate. Then, the carriage door is closed, and the rubber gasket is filled between the carriage door and the sealing plate for buffering, so that the two are in flexible contact. Thus, the sealing plate and the carriage door work together to provide a double seal for the carriage, making the sealing effect more effective and preventing gaps between the carriage and the carriage door from causing cold air to leak out and increasing power consumption.
[0016] 2. By moving the sealing plate, the rubber ring slides on the outer surface of the guide rod. The guide rod limits the movement of the sealing plate. The elasticity of the rubber ring allows the sealing plate to move with the shape of the guide rod. When the compartment needs to be closed, the sealing ring restricts the movable position of the sealing plate, and the limiting ring fills the space between the rubber ring and the sealing ring to seal. The groove in the compartment door prevents the guide rod from blocking the closing of the compartment door, thus achieving the function of adjusting the position of the sealing plate.

[0025] A refrigerated truck with high sealing performance includes:
[0026] The refrigerated truck body 1 includes a compartment 11, with compartment doors 12 connected to both sides of the compartment 11. The interior material of the compartment 11 is existing technology and can be purchased on the market. It is not considered as a technical protection point of this application, therefore, no further details are made.
[0027] The inner surface of the carriage 11 is connected to both sides of a sealing structure 2. The sealing structure 2 includes a positioning block 21. One end of the positioning block 21 is connected to a fixing screw 22. A sealing plate 23 is sleeved on the outer wall of the fixing screw 22. A nut 24 is rotatably connected to the outer surface of one end of the fixing screw 22. A rubber pad 25 is provided on the surface of the sealing plate 23.
[0028] Furthermore, positioning grooves are provided on both sides of the inner surface of the sealing plate 23, and the positioning block 21 is inserted into the positioning grooves provided in the sealing plate 23, so that the positioning block 21 can be positioned by the positioning grooves provided in the sealing plate 23.
[0029] Furthermore, a through hole is provided on one side of the positioning groove of the sealing plate 23, and the fixing screw 22 is inserted into the through hole of the sealing plate 23 to achieve positioning of the fixing screw 22 through the through hole of the sealing plate 23.
[0030] Furthermore, the fixing screw 22 and the nut 24 are connected by a thread for rotation, and the rubber pad 25 is used to separate and buffer the sealing plate 23 and the closed door 12, so as to achieve flexible contact between the sealing plate 23 and the door 12 through the rubber pad 25.
[0031] Furthermore, an adjustment mechanism 3 is provided inside both sides of the sealing plate 23. The adjustment mechanism 3 includes a rubber ring 31, a guide rod 32 is inserted inside the rubber ring 31, a limit ring 33 is sleeved on the outer wall of one end of the guide rod 32, and a sealing ring 34 is connected to the surface of one end of the limit ring 33, so as to realize the position adjustment function of the sealing plate 23 by controlling the guide rod 32.
[0032] Furthermore, grooves are provided on both sides of the bottom end of the door 12. The grooves in the door 12 are used for the guide rod 32 to pass through. The bottom sides of the sealing plate 23 are provided with through grooves. The rubber ring 31 is set inside the through grooves in the sealing plate 23, so that the rubber ring 31 is limited by the through grooves in the sealing plate 23.
[0033] Furthermore, the sealing plate 23 and the guide rod 32 are in flexible contact using a rubber ring 31, and the limiting ring 33 is filled between the rubber ring 31 and the sealing ring 34 for buffering, thereby achieving a filling and sealing between the rubber ring 31 and the sealing ring 34 through the limiting ring 33.
[0034] Working principle: When sealing a refrigerated truck, the sealing plate 23 is inserted into the compartment 11, the fixing screw 22 is inserted into the through hole of the sealing plate 23, and the positioning block 21 is inserted into the positioning groove of the sealing plate 23 to position the compartment 11 and the sealing plate 23. Then, the nut 24 is rotated and connected to the outer surface of one end of the fixing screw 22 to limit the sealing plate 23. Then, the door 12 is closed, and the rubber gasket 25 is filled between the door 12 and the sealing plate 23 for buffering, so that the two make flexible contact. Thus, the sealing plate 23 and the door 12 work together to double seal the compartment 11, making the sealing effect higher.
[0035] When adjusting the refrigerated truck with high sealing performance, the rubber ring 31 slides on the outer surface of the guide rod 32 by moving the sealing plate 23. The guide rod 32 is used to limit the movement of the sealing plate 23. The elasticity of the rubber ring 31 allows the sealing plate 23 to move with the shape of the guide rod 32. When it is necessary to close the compartment 11, the sealing ring 34 restricts the movable position of the sealing plate 23, so that the limiting ring 33 fills the space between the rubber ring 31 and the sealing ring 34 to fill and seal. The groove opened in the compartment door 12 ensures that the guide rod 32 does not obstruct the closing of the compartment door 12, thereby realizing the position adjustment of the sealing plate 23.
