[0030] In the following description, a lot of specific details are set forth in order to fully understand the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific embodiments disclosed in the following specification, the utility model will be further described in detail below in combination with drawings.

[0031] Example 1;The sealing frame of the inside of a refrigerator door, as shown in Figures 1-10 It includes horizontal profile fixed strip 1, vertical profile fixed strip 2 and corner transition piece, horizontal profile fixed strip 1 is clamped with vertical profile fixed strip 2 through corner transition piece, horizontal profile fixed strip 1, vertical profile fixed strip 2 and the inside of corner transition piece are all provided with caulking 6, stainless steel plate is clamped in caulking 6, the end of horizontal profile fixed strip 1 and the end of vertical profile fixed strip 2 are all flat angle, flat angle is easy to process, two horizontal profile fixed strips 1 and two vertical profile fixed strips 2 are combined perpendicularly, form square, the 90-degree corner is filled and clamped by corner transition piece, so that adjacent horizontal profile fixed strip 1 and vertical profile fixed strip 2 are connected, the profile fixed strip is provided with clamping groove on one side no matter horizontal or vertical, the clamping groove is inwardly spliced and installed, corner transition piece is square as a whole, one right angle side of adjacent is provided with clamping groove, the clamping groove of corner transition piece is consistent with the clamping groove of horizontal profile fixed strip 1 and vertical profile fixed strip 2, can perfectly transition and abut, is clamped into the ninety-degree square corner gap of horizontal profile fixed strip 1 and vertical profile fixed strip 2, only needs to clamp stainless steel plate in the clamping groove, so that the profile fixed strip and the bottom plate of right angle butt joint can be spliced and sealed, avoids leakage and overflow after filling foaming material, does not need to cut 45 ° assembly corner, avoids the gap problem caused by insufficient cutting process precision or operation error, reduces processing procedure, reduces processing difficulty and cost, is favorable to guarantee the forming quality of foaming layer, corner transition piece itself has the function of sealing gap, the clamping groove is composed of two layers of convex plates, one above the other.

[0032] The corner transition component includes a right-angle butt joint 3 and a gap sealing component 4. The right-angle butt joint 3 abuts against the horizontal profile strip 1 and the vertical profile strip 2, respectively. The gap sealing component 4 engages with the right-angle butt joint 3, the horizontal profile strip 1, and the vertical profile strip 2, respectively. The right-angle butt joint 3 is a square block, and its abutting ends are adapted to the horizontal profile strip 1 and the vertical profile strip 2, respectively. The protrusions on the right-angle butt joint 3 are consistent with the horizontal profile strip 1 and the vertical profile strip 2, and fit tightly against the profile strips. Figure 10 As shown, the horizontal profile strip 1 and the vertical profile strip 2 are placed at a 90-degree angle, creating a square space that matches the shape of the right-angle connector 3. The right-angle connector 3 can be precisely embedded into the square space formed by the horizontal profile strip 1 and the vertical profile strip 2 placed at a 90-degree angle, ensuring the accuracy and stability of the connection and effectively avoiding structural loosening caused by loose connections. After the right-angle connector 3 abuts against the horizontal profile strip 1 and the vertical profile strip 2, there will be two abutment seams. These seam sealing pieces 4 are used to seal the seams. The seam sealing pieces 4 directly seal the abutment between the right-angle connector 3 and the profile strips. The end is thoroughly sealed. The opening shape of the groove of the gap sealing component 4 is adapted to the protrusion of the profile fixing strip and the protrusion of the right angle butt component 3. The profile fixing strip can be inserted into the gap sealing component 4 to seal the gap generated by the abutment of the protrusion of the right angle butt component 3 and the protrusion of the profile fixing strip. The gap sealing component 4 can fit tightly into the abutment seam to form a reliable sealing barrier and ensure the quality of the foam layer. The bottom plate of the right angle butt component 3 is divided into inner and outer sides by the protrusion set in an "L" shape. The groove of the right angle butt component 3 is opened at the inner right angle end, so that the grooves of the horizontal profile fixing strip 1 and the vertical profile fixing strip 2 can be perfectly transitioned at the corner.

[0033] like Figures 2-4 As shown, the gap sealing component 4 includes a right-angle sealing block 41, which is integrally set with the right-angle connecting component 3. The right-angle sealing block 41 covers the abutting end of the right-angle connecting component 3. The horizontal profile fixing strip 1 and the vertical profile fixing strip 2 are fixedly snapped onto the two sides of the right-angle connecting component 3 by the right-angle sealing block 41. The right-angle sealing block 41 and the right-angle connecting component 3 are manufactured as a whole. The right-angle sealing block 41 directly covers the protrusion of the right-angle connecting component 3 and cannot be disassembled. The profile fixing strips are respectively inserted into the right-angle sealing block 41 until they abut against the right-angle connecting component 3. The integral right-angle sealing block 41 and the right-angle connecting component 3 have better resistance to deformation. The right-angle sealing block 41 is also "L" shaped, and its two ends are longer than the "L" shaped protrusion of the right-angle connecting component 3. The protruding part becomes the support part for the profile fixing strip. The profile fixing strip only needs to be inserted to seal and transition with the right-angle connecting component 3.

[0034] Working principle: The operator inserts the horizontal profile fixing strip 1 into the gap sealing part 4 assembled on the right angle butt joint 3, thereby completing the installation on one side of the right angle butt joint 3. Then, the vertical profile fixing strip 2 is inserted into the gap sealing part 4 on the other side.

[0035] Repeat the above steps until the horizontal profile fixing strip 1, the vertical profile fixing strip 2 and the corner transition piece form a "door" shape. Then insert a stainless steel plate into the slot 6 and install the last side profile fixing strip to complete the sealed and fixed connection.

[0036] Example 2: As Figures 5-7 As shown, the gap sealing component 4 includes a first sealing block 42 and a second sealing block 43. Both the first sealing block 42 and the second sealing block 43 are snapped onto the abutting end of the right-angle joint 3. The horizontal profile fixing strip 1 is fixedly snapped onto the right-angle joint 3 by the first sealing block 42, and the vertical profile fixing strip 2 is fixedly snapped onto the right-angle joint 3 by the second sealing block 43. Unlike the right-angle sealing block 41, which is directly fixed to the right-angle joint 3, the first sealing block 42 and the second sealing block 43 can be installed and adjusted separately. The first sealing block 42 and the second sealing block 43 are installed... During installation, the sealing blocks are snapped onto the abutting end of the right-angle butt joint 3, consistent with the assembly of the right-angle sealing block 41 and the profile fixing strip. After installation, the sealing block will also protrude a portion, which becomes the support part of the profile fixing strip, sealing the horizontal and vertical abutting gaps. The division of labor is clear. If the sealing block is damaged, only the corresponding sealing block needs to be replaced. There is no need to replace the entire gap sealing part 4 or the sealing frame. The first sealing block 42 and the second sealing block 43 are snapped onto both sides of the abutting end of the right-angle butt joint 3, and then the profile solid is aligned with the sealing block slot and pushed in.

[0037] Regardless of whether it is the right-angle sealing block 41 or the sealing block, after the profile fixing strip and the right-angle butt joint 3 are sealed and snapped together, when the foaming material is filled, the length is sufficient to block the foaming material, so that it cannot penetrate and overflow into the splice seam.

[0038] Example 3: As Figures 8-9 As shown, the right-angle connector 3 has auxiliary support rods 5 on the side walls of the horizontal profile strip 1 and the vertical profile strip 2. The horizontal profile strip 1 and the vertical profile strip 2 overlap on the auxiliary support rods 5 respectively. The auxiliary support rods 5 and the right-angle connector 3 are integrally constructed and protrude from the two abutting ends of the right-angle connector 3. They provide auxiliary support when the profile strip is inserted into the gap sealing component 4. At this time, the top surface of the auxiliary support rod 5 abuts against the bottom surface of the inner cavity of the profile strip protrusion, providing a support point for the profile strip in addition to the gap sealing component 4. This allows the profile strip to be more stably fixed on the right-angle connector 3 when subjected to external force, effectively preventing the profile strip from deforming or shifting.

[0039] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification or equivalent change made to the above embodiments according to the technical essence of the present application still falls within the protection scope of the present application technical scheme.
