[0028] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0029] Embodiment 1:

[0030] like Figures 2 to 5 A sealing mechanism for a cold storage door shown in the figure includes a sealing body installed at the bottom of the cold storage door 1, the sealing body includes a first mounting member 2, a second mounting member 3 and a sealing strip 4, the first mounting member 2 is installed on the bottom surface of the cold storage door 1, the sealing strip 4 is installed on the first mounting member 2, the second mounting member 3 is installed on the side of the cold storage door 1, and the lower end of the second mounting member 3 extends downward from the bottom surface of the cold storage door 1 and abuts against the first mounting member 2 and the sealing strip 4.

[0031] like Figure 3 As shown, the sealing strip 4 is an EPDM rubber sealing strip or an elastic rubber sealing strip, and the sealing strip 4 includes a sealing body 41, and the vertical cross-sectional shape of the sealing body 41 is "U"-shaped, and the sealing body 41 is divided into a vertical portion and an arc portion, and the vertical portion is located above the arc portion, and the vertical portion is divided into a left vertical part and a right vertical part, one of which is installed with a straight limit plate 44, and the inner side wall of the other part is installed with a convex plate 43;

[0032] The outer wall of the arcuate portion is provided with an extending portion 42 extending downward, and the extending portion 42 cooperates with the arcuate portion to doubly ensure the fit between the sealing strip and the door frame of the cold storage door 1, thereby preventing the sealing performance of the cold storage door from being reduced after the arcuate portion is deformed.

[0033] The extension 42 has an angle with the outer wall of the arc portion, that is, the vertical cross-section of the extension 42 is in an "eight" shape. The thickness of the extension 42 gradually decreases from one end to the other end, and the end of the extension 42 can contact the door frame of the cold storage door 1.

[0034] like Figure 4 As shown, the bottom surface of the first mounting member 2 is provided with a T-shaped slot 5 for mounting a straight limit plate 44 and a 7-shaped slot 6 for mounting a convex plate 43 , and the 7-shaped slot 6 is arranged close to the second mounting member 3 .

[0035] In addition, in order to better make the cold storage have a heat preservation effect, a plurality of sealing strip assemblies are provided on the bottom surface of the cold storage door 1, and adjacent sealing strip assemblies are connected, that is, the inner and outer sealing strips are connected, and both sealing strips have a heat preservation effect.

[0036] In addition, the first mounting member 2 and the second mounting member 3 are both hard mounting members, which can better ensure that the cold storage door has good rigidity when it is opened or closed, further reduce the deformation of the sealing strip 4, and ensure the insulation effect. The second mounting member 3 is a long strip plate, and the thickness of the vertical portion is greater than the thickness of the arc portion.

[0037] The arc of the arc portion is about 52.9°, and the arc of the arc portion is relatively round, so the sealing strip and the door frame of the cold storage door 1 will fit better. This can effectively prevent the leakage of cold air or hot air and the leakage of internal air, and improve the sealing performance and thermal insulation effect of the cold storage door 1. The better the sealing performance, the better the thermal insulation effect of the cold storage door 1, reducing energy consumption, and ensuring the stability of the internal temperature of the cold storage and energy-saving effect.

[0038] Specifically, firstly, two first mounting members 2 are respectively mounted on the bottom surface of the cold storage door 1, and the outer side of the first mounting plate 2 is arranged close to the edge of the cold storage door 1;

[0039] Then insert the straight stopper plate 44 and the convex plate 43 of the sealing strip 4 into the corresponding T-shaped slot 5 and the "7"-shaped slot 6 until the installation of the two sealing strips is completed;

[0040] Finally, install the second mounting plate 3. During installation, the second mounting plate 3 moves downward so that the second mounting plate 3 abuts against the sealing strip 4 to prevent the end of the sealing strip 4 with the convex plate 43 from sliding out of the "7"-shaped groove 6, thereby completing the installation of the cold storage door sealing strip.

[0041] Embodiment 2:

[0042] The difference from Example 1 is that: Figure 6 As shown, the extension portion 42 and the outer wall of the arc-shaped portion are on the same horizontal plane.

[0043] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
