Referring to fig. 1 to 3, an embodiment of the present application provides a four-layer sealing structure for a refrigerator door, including a main body portion 1, a first connecting portion 2 and a second connecting portion 3, a first sealing layer 4, a second sealing layer 5, a third sealing layer 6, and a fourth sealing layer 7, which are disposed at two ends of the main body portion 1 on the same side. The first sealing layer 4 is disposed at the other end of the body 1. The second sealing layer 5 and the third sealing layer 6 are disposed on the main body portion 1, and are located on the same side of the main body portion 1 as the first sealing layer 4. The fourth sealant layer 7 is disposed at an end of the main body portion 1, and the fourth sealant layer and the first sealant layer 4 are located on the same side of the main body portion 1. The first sealing layer 4, the second sealing layer 5, the third sealing layer 6 and the fourth sealing layer 7 are sequentially arranged on the main body part 1, and the main body part 1, the first sealing layer 4, the second sealing layer 5, the third sealing layer 6 and the fourth sealing layer 7 are all made of elastic materials.
During the use, with this cold-stored door four-layer seal structure installation fixed to cold-stored door 10 on, first connecting portion 2 hugs closely the both sides of cold-stored door 10 with second connecting portion 3, and when cold-stored door 10 closed, first sealing layer 4, second sealing layer 5, third sealing layer 6 were pressed from both sides tightly by cold-stored door 10 and door frame, because there is elasticity in each sealing layer, and then accomplish sealed cooperation between messenger's cold-stored door 10 and the door frame, form three sealedly. Compared with the traditional single sealing layer, the sealing and heat-insulating capability is greatly improved. Meanwhile, the fourth sealing layer 7 covers the gap between the refrigerated vehicle door 10 and the door frame, the first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 are isolated from the outside, and external heat is prevented from entering the interior of the refrigerated vehicle through the gap between the refrigerated vehicle door 10 and the door frame, so that the sealing and heat-insulating capacity is further improved. And further, the sealing effect of the refrigerator car is improved, so that the refrigerator car can keep a low temperature for a long time, and the frozen and refrigerated foods are prevented from being corrupted and deteriorated in the transportation process.
Referring to fig. 3, in an embodiment, the four-layer sealing structure of the refrigerator door further includes two connecting strips 8, one connecting strip 8 is disposed on the main body portion 1 between the first sealing layer 4 and the second sealing layer 5, the other connecting strip 8 is disposed on the main body portion 1 between the third sealing layer 6 and the fourth sealing layer 7, and the connecting strip 8 fixes the main body portion 1 to the refrigerator door 10 through a screw 9. Wherein, the connecting strip 8 adopts metal material to make, specifically can be aluminium, steel etc. and the connecting strip 8 is thin slice strip structure, fixes the connecting strip 8 on cold-stored door 10 through adopting screw 9 (screw), and then makes the connecting strip 8 compress tightly main part 1 on cold-stored door 10.
In one embodiment, the fourth sealant 7 is on the outside of the refrigerated vehicle door 10, and the fourth sealant 7 has an arc-shaped configuration that curves toward the inside of the refrigerated vehicle door 10. Through setting up fourth sealing layer 7 in the outside of refrigerator door 10 to make fourth sealing layer 7 towards refrigerator door 10 inside bend, and then make when refrigerator door 10 closes, the terminal of fourth sealing layer 7 supports the door frame of refrigerator door 10, and because fourth sealing layer 7 incurves, and then under the effect of elastic force, make the terminal of fourth sealing layer 7 keep closely laminating with the refrigerator door outer wall, cover the regional connection between refrigerator door 10 and the door frame and separate from the external world, further improve the sealed heat preservation ability of refrigerator door 10.
In one embodiment, the first sealant layer 4, the second sealant layer 5, and the third sealant layer 6 are all arc-shaped structures bent toward the fourth sealant layer 7. By arranging the first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 to be of an arc-shaped structure bent towards the fourth sealing layer 7, when the refrigerator door 10 is closed, the first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 are bent in advance, so that the first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 are further bent towards the fourth sealing layer 7 (namely towards the outer side of the refrigerator door 10) until being tightly attached to the door frame, and by arranging the first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 to be pre-bent towards the direction to be subjected to compression bending in advance, so that the subsequent first sealing layer 4, the second sealing layer 5 and the third sealing layer 6 are bent and clamped between the door frame and the refrigerator door 10 for sealing, and the sealing action of the refrigerator door 10 is smoother, and saves more labor.
In one embodiment, the fourth sealant 7 is wider than the first sealant 4, the second sealant 5, and the third sealant 6. By enabling the width of the fourth sealing layer 7 to be maximum, when the fourth sealing layer 7 covers the connecting area between the refrigerator door 10 and the door frame, the fourth sealing layer can cover more completely, and the capacity of the fourth sealing layer 7 for blocking external hot air from entering the refrigerator door 10 and the door frame from the matching position is improved.
In one embodiment, the surfaces of the first and second connecting portions 2 and 3 and the main body portion 1 contacting the refrigerator door 10 are provided with adhesive layers. Through setting up the adhesive layer, cooperation connecting strip 8 for it is inseparabler to be connected between four layers of seal structure of refrigerated door and the door, prevents to have between four layers of seal structure of refrigerated door and the door to leak, improves the heat preservation sealing capacity of refrigerator car.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
