Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck compartment technology, specifically to a protective structure for refrigerated truck compartments. Background Technology

[0002] A refrigerated truck compartment is an enclosed compartment for storing goods at low temperatures. It is usually installed on the vehicle's transport frame and then used with a refrigeration system to maintain a constant temperature inside the compartment, ranging from -25℃ to 15℃. It can meet the refrigeration needs of ordinary goods and is widely used in industries such as food, pharmaceuticals, and chemicals. Common refrigerated truck compartments are equipped with protective structures to ensure that goods are protected from physical damage, temperature fluctuations, and environmental factors during transportation.

[0003] Common refrigerated truck compartments require an additional protective structure on the side of the door closest to the compartment to isolate the gap between the door frame and the door body, as well as the gap between the doors. The common practice is to glue or install rubber gaskets on the contact surfaces and achieve a seal between the doors by squeezing the rubber gaskets when the door is closed.

[0004] However, during prolonged use, the sealing strips of refrigerated trucks are easily damaged and fall off due to compression, which reduces the sealing effect of the refrigerated compartment and consequently reduces the protection of the environment inside the compartment, thus affecting the overall protection effect. Utility Model Content

[0005] In view of the deficiencies in the existing technology, this utility model provides a protective structure for refrigerated truck compartments to improve the sealing effect of refrigerated truck compartments, thereby enhancing the protective effect.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a protective structure for a refrigerated truck compartment, including a door and an inner door. The inner door is in contact with the inner wall of the refrigerated truck compartment. A male and female groove is provided on the intermediate layer. A U-shaped rubber strip is sleeved in the male and female groove. A U-shaped tube gasket is provided between the two U-shaped rubber strips. An intermediate layer is provided on the side of the door near the inner door. The intermediate layer has a split structure. Four insertion holes are provided on the side of the intermediate layer near the door. A connecting rod is inserted into the insertion holes. A pressure rod is threaded to both sides of the connecting rod. The pressure rod is inserted into the intermediate layer. A protrusion is fixedly connected to one end of the pressure rod. The door is in contact with one end of the truck frame.

[0007] As a preferred technical solution of this utility model, a hidden groove is provided at the position corresponding to the pressure rod in the intermediate layer. The hidden groove corresponds to the protrusion of the pressure rod. By setting the hidden groove, the impact of the pressure rod protrusion on the door closure can be reduced.

[0008] As a preferred technical solution of this utility model, the intermediate layer is provided with strip grooves on all four sides of the insertion hole, and the strip grooves are in contact with protrusions. The protrusions are fixedly connected to the connecting rod. By setting the protrusions and strip grooves, the connection of multiple intermediate layers can be provided.

[0009] As a preferred technical solution of this utility model, a connecting pipe is fixedly connected to one side of the loop sleeve gasket, and a check valve is provided inside the connecting pipe. By providing the connecting pipe and the check valve, it is convenient to inflate the loop sleeve gasket with air through the inflation device.

[0010] As a preferred technical solution of this utility model, a receiving groove is provided on one side of the upper side of the intermediate layer. The receiving groove corresponds to the connecting pipe. By providing the receiving groove, the connecting pipe can be accommodated.

[0011] This utility model has the following advantages: by installing a split intermediate layer and inner door structure on the side of the car door near the car body, and providing connection through pressure rod and connecting rod, and further by setting yin and yang grooves on the opposite side of the intermediate layer to provide contact when the door is closed, the sealing and protection effect is improved. At the same time, the pressure rod can be removed to separate the intermediate layer during disassembly, so as to disassemble, replace and inflate the U-shaped tube gasket, which can improve the disassembly efficiency.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-5 The protective structure for a refrigerated truck compartment shown includes a door 1 and an inner door 3. The inner door 3 contacts the inner wall of the refrigerated truck compartment. A groove 4 is provided on the intermediate layer 2, which is a polyurethane insulation layer structure wrapped with aluminum foil. A U-shaped rubber strip 5 is fitted inside the groove 4, and a U-shaped tube gasket 6 is placed between the two U-shaped rubber strips 5. By setting the U-shaped tube gasket 6, a stable sealing effect can be provided when the two intermediate layers 2 are pressed together. The door 1 has a U-shaped rubber strip 5 on the side closest to the inner door 3. Layer 2 and intermediate layer 2 are split structures. The intermediate layer 2 has four insertion holes 7 on the side near the door 1. Connecting rods 8 are inserted into the insertion holes 7. Pressure rods 9 are threaded to both sides of the connecting rods 8. By removing the four pressure rods 9 on a single intermediate layer 2, the two intermediate layers 2 can be separated, and the U-shaped rubber strip 5 and U-shaped tube gasket 6 can be removed, so as to perform replacement, inflation and other operations as needed. The pressure rods 9 are inserted into the intermediate layer 2, and a protrusion is fixedly connected to one end of the pressure rod 9. The door 1 contacts the frame at one end.

[0020] The middle layer 2 has a hidden groove 10 at the position corresponding to the pressure rod 9. The hidden groove 10 corresponds to the protrusion of the pressure rod 9. By setting the hidden groove 10, the protrusion at the pressure rod 9 can be hidden, reducing the impact of the protrusion on the closure of the door 1.

[0021] Among them, the middle layer 2 has strip grooves on all four sides of the insertion hole 7, and the strip grooves are in contact with the protrusions 11. The protrusions 11 are fixedly connected to the connecting rod 8. By setting the protrusions 11 and the strip grooves, the screw holes on the protrusions 11 that are connected to the pressure rod 9 can stably correspond to the pressure rod 9.

[0022] Among them, a connecting pipe 14 is fixedly connected to one side of the U-shaped tube gasket 6, and a check valve 13 is installed inside the connecting pipe 14. By setting the connecting pipe 14 and the check valve 13, it is easy to inflate and provide a stable sealing effect.

[0023] The middle layer 2 has a receiving groove 12 on one side of the upper side. The receiving groove 12 corresponds to the connecting pipe 14. By setting the receiving groove 12, it is easy to place the connecting pipe 14.

[0024] Working principle: By inflating the connecting pipe 14, the inside of the loop sleeve gasket 6 is inflated. When the door 1 is relatively closed, the casting is squeezed under the action of the male and female grooves 4, thereby sealing the male and female grooves 4 and achieving the effect of sealing the gap of the door 1. It can prevent airflow. When the loop sleeve gasket 6 needs to be disassembled due to damage or needs to be inflated, the four pressure rods 9 of the single intermediate layer 2 can be removed, and the loop rubber strip 5 or the loop sleeve gasket 6 can be detached, which can facilitate installation and provide sealing protection.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
