An interlocking protrusion 22 is provided on the vertical L-shaped section of the U-shaped frame 21. A rubber sealing strip 26 is interlocked on the interlocking protrusion 22.

[0028] The rubber sealing strip 26 has a T-shaped cross-section, and positioning grooves 27 are provided on both sides of the vertical section of the T-shaped cross-section of the rubber sealing strip 26. The rubber sealing strip 26 is fitted into the inner side of the U-shaped frame 21 in a U-shape. The side of the U-shaped frame 21 facing the cabinet 1 is provided with a fixed frame 24 that is spliced ​​with it. The cross-section of the fixed frame 24 and the U-shaped frame 21 are spliced ​​to form a U-shape. The fitting protrusion 22 and one end of the fixed frame 24 are respectively fitted into both sides of the vertical section of the T-shaped cross-section of the rubber sealing strip 26.

[0029] A magnetic strip 210 is provided on the side opposite to the horizontal and vertical sections of the T-shaped cross-section of the rubber sealing strip 26. A uniformly distributed spring 211 is provided on the side opposite to the rubber sealing strip 26 of the magnetic strip 210.

[0030] The rotating connection between the U-shaped frame 21 and the cabinet 1 is located on the outer side of its L-shape parallel to the opening of the cabinet 1. The fitting protrusion 22 is fitted into the positioning groove 27 located on the inner side of the U-shape of the rubber sealing strip 26. The rubber sealing strip 26 is hollow.

[0031] The cabinet 1 has a sealing groove 13 on its opening surface. A second magnetic strip 214 is embedded and fixed in the sealing groove 13. The T-shaped vertical section end of the rubber sealing strip 26 is embedded in the sealing groove 13 and attached to the side of the second magnetic strip 214.

[0032] The side of the U-shaped frame 21 parallel to the opening of the cabinet 1 has evenly distributed limiting holes 28. Limiting rods 29 are inserted through the limiting holes 28. The first magnetic strip 210 is fixedly connected to the ends of the multiple limiting rods 29 facing the cabinet 1. Multiple springs 211 are respectively sleeved on the outside of the multiple limiting rods 29. The springs 211 are located between the L-shaped horizontal section of the U-shaped frame 21 and the first magnetic strip 210. The ends of the multiple limiting rods 29 opposite to the first magnetic strip 210 are all fixedly connected to baffles 212.

[0033] A fixing strip 23 is fixedly connected to the same side of the spiral frame 21 and the first magnetic strip 210, and the fixing frame 24 is fitted onto the side wall of the fixing strip 23. The fixing strip 23 is located on the side opposite to the rubber sealing strip 26 of the fixing frame 24, and is located inside the square shape formed by the spiral frame 21 and the fixing frame 24.

[0034] Both the fixing strip 23 and the fixing frame 24 have threaded holes through them on their sides, and screws 25 for fastening are threaded through and connected to the threaded holes.

[0035] A protective cover 213 is fixed on the side wall opposite to the cabinet 1 of the U-shaped frame 21, and the protective cover 213 covers and is fixed to the outside of the baffle 212. A handle 12 is fixed to the outer wall of the protective cover 213, and a protective glass 11 is fixed to the inside of the U-shaped frame 21.

[0036] During operation, the magnetic sealing structure of traditional display cabinet glass doors is prone to aging and damage of the magnetic rubber sealing strip after prolonged use, which affects the sealing effect. The replacement of the magnetic rubber sealing strip is expensive, which increases the cost of use. In addition, if the sealing strip is not installed tightly with the cabinet door, there will be gaps, which can easily reduce the sealing effect. In this solution, the initial turntable lower spring 211 will always push the first magnetic strip 210 towards the fitting protrusion 22, so that the first magnetic strip 210 moves towards the fitting protrusion 22 and the side wall adjacent to the connecting section of the fixed frame 24 and the fixed strip 23. Then, the first magnetic strip 210 will press and adhere the straight section of the T-shaped section of the rubber sealing strip 26 to the fitting protrusion 22 and the side wall adjacent to the connecting section of the fixed frame 24 and the fixed strip 23, so as to fit and fix the rubber sealing strip 26.

[0037] When opening and closing the cabinet door assembly 2, the cabinet door assembly 2 is rotated by holding the handle 12, causing the cabinet door assembly 2 to rotate around the rotational connection shaft with the cabinet body 1. When the cabinet door assembly 2 rotates to the opening of the cabinet body 1, the vertical section of the T-shaped cross-section of the rubber sealing strip 26 will be embedded in the sealing groove 13 and will be attracted to each other under the magnetic action of the first magnetic strip 210 and the second magnetic strip 214. Under the attraction force of the first magnetic strip 210 and the second magnetic strip 214, the rubber sealing strip 26 will deform, causing the vertical section of the T-shaped cross-section of the rubber sealing strip 26 to expand and fill the sealing groove 13, thereby sealing the opening of the cabinet body 1 and achieving the sealing effect of the cabinet body 1. Under the squeezing action of the first magnetic strip 210, the sealing effect between the rubber sealing strip 26 and the U-shaped frame 21 and the fixed frame 24 is guaranteed. Under the expansion action of the vertical section of the rubber sealing strip 26, the sealing effect between it and the cabinet body 1 is guaranteed, thereby ensuring a tight sealing effect.

[0038] When the rubber sealing strip 26 ages and becomes damaged, first unscrew the screw 25 from the threaded hole of the fixing frame 24. Then, the fixing frame 24 can be removed from the outer wall of the fixing strip 23 and moved out of the positioning groove 27 on the outer side of the vertical section of the rubber sealing strip 26. Then, the rubber sealing strip 26 can be removed from the fitting protrusion 22 and removed from the U-shaped frame 21. Then, the new rubber sealing strip 26 is fitted onto the fitting protrusion 22. When installing the rubber sealing strip 26, first push the first magnetic strip 210 towards the protective cover 213 and fit the fitting protrusion 22 into the positioning groove 27 on the inner side of the vertical section of the rubber sealing strip 26. Then, fasten the fixing frame 24 on the inner side and fix the fixing frame 24 to the side wall of the fixing strip 23 with screws 25. Then, fix the rubber sealing strip 26 between the U-shaped frame 21 and the fixing frame 24, thus completing the replacement of the rubber sealing strip 26.

[0039] It achieves the function of sealing the display case, and has a better sealing effect than the traditional display case sealing structure. It also effectively reduces the replacement cost of the sealing strip and saves on usage costs.
