Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration devices, in particular to a door structure of a refrigeration device such as a refrigerator, a wine cabinet and the like. Background Art

[0002] At present, refrigeration devices, especially large-capacity refrigerators, wine cabinets, etc., use large-sized and long door bodies. After the door body is foamed, the long door frame is prone to deformation. The deformation will cause the surface of the door body to be uneven, which will seriously affect the appearance of the refrigerator. The Chinese patent application number 201521002760.2 discloses a reinforced frame of a refrigerator door body, which is provided with a U-shaped reinforcing iron in the door body frame, and the U-shaped reinforcing iron faces the inner side of the frame. The U-shaped reinforcing iron increases the strength of the frame, making it less likely for the door body to deform after foaming. The existing U-shaped reinforcing iron is arranged toward the inner side of the frame, and it mainly relies on the two sides of the U-shaped reinforcing iron to provide strength support for the frame. This method has a small support surface and a deviation in the support effect. When facing the current large-capacity refrigeration devices, it is difficult to effectively solve the technical problem of deformation of large-sized door bodies and door frames. Therefore, there is an improvement. Summary of the Invention

[0019] EMBODIMENT

[0020] REFERENCE Figures 1 to 6 A kind of structure for improving the foaming deformation of the door body of cold storage device, it includes door body 1. The refrigerator (not shown in the drawing) is specifically used as refrigerator door in the embodiment of the present application, and the door body 1 is used as refrigerator door.

[0021] As Figure 1 And Figure 2 The front surface of door body 1 is provided with door panel 11, the back surface is provided with door lining 12, and the two sides are symmetrically provided with frame 13, and the door body 1 is filled with foaming material to form foaming layer 14. As Figure 1 And Figure 4, the first reinforcing strip 2 is arranged in the foaming layer 14 along the frame 13, and the middle part of the first reinforcing strip 2 is provided with a plurality of uniformly arranged first through holes 21.

[0022] In the above structure, the first reinforcing strip 2 is connected with the door panel 11, the door lining 12, the upper beam (not shown in the figure) and the lower beam (not shown in the figure) of the door body 1 together with the frame 13 to form a shell structure with a foaming inner cavity, and then the foaming material is filled into the foaming inner cavity to perform a foaming process, so that the foaming layer 14 is formed in the door body 1. In the foaming process, the foaming material presses the first reinforcing strip 2 towards the frame 13, so as to realize the reinforcing and supporting effect of the first reinforcing strip 2 on the frame 13. At the same time, the foaming material is pressed into the first through holes 21 of the first reinforcing strip 2 and is pressed against the frame 13, and then the foaming material in the first through holes 21 realizes the clamping and positioning effect on the first reinforcing strip 2, so that the first reinforcing strip 2 is more stably installed on the inner side of the frame 13, and the long-term, firm and stable supporting effect on the frame 13 is realized, thereby avoiding the deformation of the frame 13 of the door body 1 after long-term use.

[0023] Further, as shown in Figure 2 and Figure 3 , the two sides of the first reinforcing strip 2 are bent away from the frame 13, so that the cross section of the first reinforcing strip 2 is in a U-shaped structure. In the above structure, the structure of the first reinforcing strip 2 in the U-shaped structure is more stable and is not easy to bend and deform, thereby being able to strengthen the supporting effect on the frame 13; and the two sides of the first reinforcing strip 2 are bent away from the frame 13, so that the direction of the first reinforcing strip 2 is towards the inner side away from the frame 13, and then the middle part of the first reinforcing strip 2 is more closely attached to the inner side of the frame 13, thereby playing a role in strengthening the support on the frame 13.

[0024] Further, as shown in Figure 1 and Figure 2 , the door lining 12 is symmetrically provided with a convex strip part 121 protruding away from the door panel 11, the convex strip part 121 is arranged in a vertical long strip structure, and the foaming layer 14 is provided with a vertical long strip-shaped second reinforcing strip 3 along the convex strip part 121.

[0025] In the above structure, when the shell structure with a foaming inner cavity is connected, the second reinforcing strip 3 is assembled together with the door lining 12. In the foaming process, the foaming material simultaneously presses the second reinforcing strip 3 towards the convex strip part 121, so as to realize the reinforcing and supporting effect of the second reinforcing strip 3 on the convex strip part 121. The two symmetrical convex strip parts 121 are used for hanging a hanging basket or a hanging box (not shown in the figure), so as to avoid the deformation of the convex strip part 121 after being too long. Therefore, the second reinforcing strip 3 is arranged on the inner side of the convex strip part 121, so as to realize the reinforcing and supporting effect of the second reinforcing strip 3 on the convex strip part 121.

[0026] Further, as shown in Figure 6The middle part of the second reinforcing strip 3 has a plurality of second through holes 31 arranged uniformly. The foaming process makes the foaming material also press into the second through holes 31 of the second reinforcing strip 3 and press against the convex strip part 121. Further, the foaming material in the second through holes 31 realizes the clamping and positioning of the second reinforcing strip 3, so that the second reinforcing strip 3 is more stably installed inside the convex strip part 121, realizes the long-term, firm and stable support of the convex strip part 121, and avoids the deformation of the convex strip part 121 of the door body 1 after long-term use.

[0027] In addition, it is particularly pointed out that, since the convex strip part 121 on the door lining 12 is usually narrow, the middle part of the second reinforcing strip 3 is difficult to completely fit the inside of the convex strip part 121, therefore, the foaming material can be filled between the second reinforcing strip 3 and the convex strip part 121 through the second through holes 31, so as to avoid the gap between the second reinforcing strip 3 and the convex strip part 121.

[0028] Further, as shown in Figure 2 and Figure 5 , the two sides of the second reinforcing strip 3 are bent away from the convex strip part 121, so that the cross section of the second reinforcing strip 3 is in U-shaped structure. Similarly, the U-shaped structure of the second reinforcing strip 3 is more stable and difficult to bend and deform, and further can strengthen the support of the convex strip part 121; and the two sides of the second reinforcing strip 3 are bent away from the convex strip part 121, so that the direction of the second reinforcing strip 3 is away from the inside of the convex strip part 121, and further the middle part of the second reinforcing strip 3 is pressed to the inside of the convex strip part 121, so as to strengthen the support of the convex strip part 121.
