Technical Field

[0001] The utility model belongs to the technical field of cold chain transportation, and in particular relates to a door frame structure with a leak-proof function. Background Art

[0002] The door frame of a refrigerated truck is a key component specially designed to maintain the low temperature inside the compartment. It is made of high-strength metal materials and equipped with low-temperature resistant, highly elastic sealing strips to ensure a tight seal between the door body and the door frame to prevent cold air leakage and external heat entry. At the same time, it has good structural strength and thermal insulation properties to ensure the refrigeration quality of the goods and the transportation efficiency of the vehicle.

[0003] During normal use, the door frame of the refrigerated truck may cause deformation of the door panel due to frequent opening and closing of the door, which may cause the door to not be completely closed, leaving a gap. In addition, over time, the rubber pad on the door frame may age, which will also cause the sealing performance of the door frame to decrease, making it impossible for the door to be closed tightly. These situations will affect the insulation effect of the refrigerated truck, increase energy consumption, and may cause damage to the transported goods. Utility Model Content

[0025] Example 1

[0026] Reference Figure 1 , Figure 2 and Figure 3 , is the first embodiment of the utility model, which provides a door frame structure with a leak-proof function, including:

[0027] The frame mechanism 100 and the door panel mechanism 200 , the frame mechanism 100 comprises a door frame 101 , a reserved groove 102 is opened on the inner side wall of the door frame 101 , a reserved hole 104 is opened on the inner side wall of the door frame 101 , and a sealing plate 103 is fixedly installed on the outer side wall of the door frame 101 .

[0028] Specifically, a first transmission gear 105 is fixedly mounted on the inner wall of the reserved groove 102 , and a winding spring 106 is disposed inside the first transmission gear 105 .

[0029] When in use, when the door is opened, the winding spring 106 is tightened, and when it is relaxed, the winding spring 106 releases force, driving the first transmission gear 105 to rotate, and the first rotating gear drives the second rotating gear to rotate, closing the stainless steel door 201.

[0030] In summary, the winding spring 106 is tightened when the door is opened, and releases force when it is relaxed, thereby driving the first transmission gear 105 to rotate, and then the stainless steel door 201 is automatically closed through the transmission between the gears. This design significantly improves the automatic reset ability and sealing performance of the door, reduces the labor intensity of the operator, extends the service life of the door, and ensures that the force is uniform each time the door is closed, effectively improving the overall performance and reliability of the refrigerated vehicle door.

[0031] Example 2

[0032] Reference Figure 4 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides a door panel mechanism 200 to ensure airtightness.

[0033] Specifically, the door panel mechanism 200 includes a stainless steel door 201, a hinge 203 is fixedly connected to the outer wall of the stainless steel door 201, a second transmission gear 204 is fixedly installed on the outer wall of the hinge 203, a sealing strip 202 is fixedly installed on the outer wall of the stainless steel door 201, and a bearing seat 205 is fixedly installed on the outer wall of the stainless steel door 201.

[0034] Furthermore, a limit tube 209 is movably connected to the outer wall of the bearing seat 205, a limit spring 214 is fixedly installed on the inner side of the limit tube 209, a connecting plate 215 is fixedly installed on the outer wall of the limit spring 214, a push rod 208 is fixedly installed on the outer wall of the connecting plate 215, a rounded corner block 207 is fixedly connected to the outer wall of the connecting plate 215, a fixed block 211 is fixedly installed on the outer wall of the stainless steel door 201, and a transmission shaft 206 is fixedly installed on the outer wall of the fixed block 211.

[0035] When in use, when opening the door, pull the pull rod to release the rounded corner limit block. When closing the door, push the stainless steel door 201 inward, the limit spring 214 contracts inward, and the rounded corner limit block reaches the specified position, and the rounded corner limit block pops out to fix the door.

[0036] In summary, the stability of the door after closing is effectively ensured, the displacement of the door body caused by vehicle vibration is prevented, the sealing and safety of the door are improved, while the door closing operation is simplified, the convenience of use is improved, and the service life of the door is extended.

[0037] Example 3

[0038] Reference Figure 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides another usage of the door panel mechanism 200.

[0039] Specifically, an eccentric wheel 217 is sleeved on the outer wall of the transmission shaft 206 , a bevel gear 213 is fixedly mounted on the outer wall of the transmission shaft 206 , and a third transmission gear 212 meshing with the bevel gear 213 is disposed on the outer wall of the bevel gear 213 .

[0040] Furthermore, a rack 216 meshing with the third transmission gear 212 is disposed on the outer wall thereof, and a handle 210 is fixedly mounted on the outer wall of the third transmission gear 212 .

[0041] When in use, after the door is closed, the handle 210 is twisted, the rack 216 drives the bevel gear 213 to rotate, the bevel gear 213 drives the transmission shaft 206 to rotate, and the transmission shaft 206 drives the eccentric disk to fix the limiting tube 209. After being locked, the sealing strip 202 and the sealing plate 103 fit tightly.

[0042] In summary, after the door is closed, by twisting the handle 210, the rack 216 drives the bevel gear 213 to rotate, and then drives the transmission shaft 206 to rotate, and the transmission shaft 206 drives the eccentric disk to fix the limiting tube 209. The locking mechanism ensures that the sealing strip 202 and the sealing plate 103 fit tightly, thereby significantly improving the sealing performance of the door body, effectively preventing cold air leakage, and ensuring the refrigeration effect. At the same time, it enhances the safety and durability of the door, simplifies the door locking process, and improves the convenience of user operation.
