[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1 - Figure 5 As shown, a fixing structure for a refrigerator glass panel and a door frame includes a refrigerator door frame 1. A connecting groove 2 is provided on one side of the back of the refrigerator door frame 1. Multiple threaded holes 3 are provided on the inner wall of the connecting groove 2. The refrigerator door frame 1 is rotatably connected to the refrigerator through the connecting groove 2 and the threaded holes 3 in conjunction with an external connecting structure, making it convenient for users to open and close the refrigerator door.

[0025] Multiple first fixing plates 5 are fixedly welded to the inner wall of the refrigerator door frame 1. A tube 6 is fixedly connected to the side of the first fixing plate 5 near the glass panel body 8. The tube 6 is made of metal. Multiple annular expansion grooves 7 are opened at the end of the tube 6 away from the first fixing plate 5. The wall thickness of the tube 6 gradually increases from the end away from the first fixing plate 5 to the end near the first fixing plate 5. When the inside of the tube 6 is compressed, the end of the tube 6 can expand along the expansion grooves 7, thereby increasing the outer diameter of the end of the tube 6 away from the first fixing plate 5.

[0026] A reinforcing ring is fixedly sleeved on the outer surface of the end of the insertion tube 6 near the first fixing plate 5. The reinforcing ring is used to reinforce the end of the insertion tube 6 near the first fixing plate 5, so as to avoid the problem of excessive expansion of the expansion groove 7 after the insertion tube 6 is compressed, which would cause the insertion tube 6 to break.

[0027] A glass panel body 8 is provided on the side of the refrigerator door frame 1 away from the connecting groove 2. A second fixing plate 9 is connected to the side of the glass panel body 8 close to the refrigerator door frame 1. A hot-melt plastic plate 10 is fixedly connected to the second fixing plate 9. One side of the second fixing plate 9 is hot-melt connected to the glass panel body 8 through the hot-melt plastic plate 10, so as to fix the second fixing plate 9 to the glass panel body 8.

[0028] On the other side of the second fixing plate 9, an outer sleeve 11 is fixedly connected to the insertion tube 6. The inner diameter of the outer sleeve 11 near the insertion tube 6 is equal to the outer diameter of the insertion tube 6, and the inner diameter of the outer sleeve 11 gradually increases from the end near the insertion tube 6 to the end away from the insertion tube 6.

[0029] An extrusion rod 12, which is fixedly connected to the second fixing plate 9 at one end, is provided inside the outer tube 11. The extrusion rod 12 has a frustum-shaped structure. The end of the extrusion rod 12 with a larger diameter is fixed to the second fixing plate 9. An annular gap 13 is formed between the periphery of the extrusion rod 12 and the inner wall of the outer tube 11. The width of the annular gap 13 is set according to the wall thickness of the insertion tube 6. When the insertion tube 6 is inserted into the outer tube 11, the extrusion rod 12 provided inside the outer tube 11 will be inserted into the insertion tube 6 from the end of the insertion tube 6 in the opposite direction. Since the extrusion rod 12 has a frustum-shaped structure, during the process of inserting the insertion rod 12 into the insertion tube 6, it will compress the end of the insertion tube 6 located inside the outer tube 11 to expand and increase along the expansion groove 7, so that the insertion tube 6 and the outer tube 11 are stably connected. Thus, the glass panel body 8 is stably connected to the refrigerator door frame 1 without the need for glue application, saving processes and greatly improving the installation efficiency of the glass panel body 8.

[0030] A positioning groove 4 is provided on the side of the refrigerator door frame 1 away from the connecting groove 2. The size of the inner cavity of the positioning groove 4 is adapted to the size of the glass panel body 8. The depth of the positioning groove 4 is equal to the edge thickness of the glass panel body 8. The positioning groove 4 not only facilitates the positioning of the glass panel body 8 during installation, but also seals and protects the edge of the glass panel body 8, greatly improving the service life of the glass panel body 8.

[0031] It should be noted that during use, the second fixing plate 9 is first hot-stamped to the appropriate position of the glass panel body 8 using the hot-melt plastic plate 10. After placing the refrigerator door frame 1 on the external assembly table, the side of the glass panel body 8 connected to the second fixing plate 9 is aligned with the positioning groove 4 opened on the refrigerator door frame 1, and the glass panel body 8 is pressed down. At this time, the outer sleeve 11 installed on the second fixing plate 9 will be sleeved on the corresponding insertion tube 6 under pressure. When the insertion tube 6 is inserted into the outer sleeve 11, the extrusion rod 12 set in the outer sleeve 11 will be inserted into the insertion tube 6 from the end of the insertion tube 6 in the opposite direction. Since the extrusion rod 12 has a frustum-shaped structure, during the process of inserting the insertion rod 12 into the insertion tube 6, it will extrude the end of the insertion tube 6 located in the outer sleeve 11 to expand and enlarge along the expansion groove 7, so that the insertion tube 6 and the outer sleeve 11 are stably connected, thereby stably connecting the glass panel body 8 to the refrigerator door frame 1. There is no need for the glue application step, saving the process and greatly improving the installation efficiency of the glass panel body 8.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
