Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator sliding doors, in particular to a refrigerator glass sliding door. Background Art

[0002] The refrigerator is a commonly used household appliance in life. Its design combines practicality and aesthetics. It is not only convenient for users to store and retrieve food, but also can display the items stored inside the refrigerator, while also improving the overall aesthetics of the kitchen. The refrigerator used to display food is a sliding door display refrigerator. This type of refrigerator uses a sliding door made of transparent glass, which allows users to see the food inside from the outside and facilitates the storage and retrieval of food.

[0003] The traditional sliding door of a display refrigerator adopts a sliding method that is achieved by sliding the door frame of the sliding door against the limit position inside the refrigerator or by moving wheels. This sliding door has a large friction during the sliding process. After long-term use, the sliding position will be greatly worn, affecting the sliding effect and making it difficult to use. Therefore, it is urgent to design a refrigerator glass sliding door to solve the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a refrigerator glass sliding door, which adopts the method of permanent magnet repulsion to allow the transparent glass sliding door to push the door body upward through magnetic force when sliding in both directions, so as to avoid friction between the door body and the refrigerator. At the same time, the thrust of the magnetic force can push the door body's own weight upward to avoid force on the sliding connection, which can improve the long-term sliding stability of the glass sliding door.

[0005] The utility model provides a refrigerator glass sliding door:

[0006] The invention comprises a refrigerator, wherein a transparent glass sliding door that can be opened and closed in both directions is provided on the inner side of the front face of the refrigerator for limited sliding. A first permanent magnet is provided at the positions where the transparent glass sliding doors are connected at the upper and lower ends of the refrigerator. A second permanent magnet is provided on the inner side of the upper and lower ends of the transparent glass sliding doors for limited sliding. The first permanent magnet and the second permanent magnet repel each other at their opposite surfaces. Lifting and sliding internally on both sides of the transparent glass sliding doors are provided with lifting and adjusting push rods that are fitted and staggered. A limiting adjusting rotating rod is provided at the center of the staggered position of the lifting and adjusting push rods. The limiting adjusting rotating rod is driven by bidirectional meshing with the lifting and adjusting push rods.

[0007] Preferably, a sealed slide groove is provided at the position where the refrigerator is connected to the first permanent magnet, and a limited lifting opening is provided at the position where the transparent glass sliding door is connected to the second permanent magnet. The first permanent magnet slides inside the sealed slide groove, and the second permanent magnet slides inside the limited lifting opening. The first permanent magnet and the second permanent magnet are connected to the refrigerator and the transparent glass sliding door in a sliding manner, so that the permanent magnets can be replaced when damaged, and the distance between the permanent magnets can be adjusted.

[0008] Preferably, a slidably connected permanent magnet slide is passed through the inner side of the sealing slide groove, the first permanent magnet is located on the inner side of the permanent magnet slide, one end of the permanent magnet slide extends to the outside of the refrigerator, and the end of the permanent magnet slide located on the outside of the refrigerator is connected to a driving pull member. The permanent magnet slide and the driving pull member arranged inside it can facilitate the disassembly of the first permanent magnet and quickly complete the separation of the first permanent magnet from the inside of the refrigerator.

[0009] Preferably, tooth plates are provided at staggered positions of the lifting and adjusting push rods, and tooth blocks arranged equidistantly are fixed on opposite surfaces of the tooth plates. The limit adjustment rotating rod is meshed with the tooth blocks. The design of the tooth plates and the tooth blocks allows the limit adjustment rotating rod to have higher adjustment accuracy when adjusting the second permanent magnet.

[0010] Preferably, a gear rod is provided at a position of the limit adjustment rotating rod between the lifting adjustment push rods, and the gear rod is meshed with a gear block.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0022] Please see attached Figure 1-Figure 4 The present invention provides a refrigerator glass sliding door, which comprises:

[0023] The refrigerator 1 has a staggered transparent glass sliding door 2 which is bidirectionally slidably connected to the inner side of the front side of the refrigerator 1. The transparent glass sliding door 2 is slidingly connected to the inside of the refrigerator 1 in a sealed manner, so as to block the cold air inside the refrigerator 1.

[0024] A sealed slide groove 7 is provided at the position where the refrigerator 1 is connected to the transparent glass sliding door 2, and a permanent magnet slide seat 8 is slidably connected to the inner side of the sealed slide groove 7, and a first permanent magnet 3 is provided on the inner side of the permanent magnet slide seat 8. The permanent magnet slide seat 8 can facilitate the disassembly and replacement of the first permanent magnet 3 and the inside of the refrigerator 1. A limited lifting opening 10 is provided on the inner side of the upper and lower ends of the transparent glass sliding door 2, and a second permanent magnet 4 is lifted and slidably connected to the inner side of the limited lifting opening 10. Through the arrangement of the first permanent magnet 3 and the second permanent magnet 4, when the transparent glass sliding door 2 is in use, the repulsive reaction between the two permanent magnets can be used to push the bottom of the transparent glass sliding door 2 to separate from the connection between the refrigerator 1, thereby reducing the friction between the transparent glass sliding door 2 and the inner bottom surface of the refrigerator 1, improving the sliding effect between the transparent glass sliding door 2 and the refrigerator 1, and being able to maintain the sliding effect between the transparent glass sliding door 2 and the refrigerator 1 for a long time.

[0025] It should be noted that the opening of the limit lifting opening 10 allows the second permanent magnet 4 to be lifted and slid, thereby adjusting the gap and sealing performance at the connection between the upper and lower ends of the transparent glass sliding door 2 and the refrigerator 1 .

[0026] One end of the permanent magnetic slide 8 located outside the refrigerator 1 is connected to a driving pull member 9 , which can facilitate the pulling operation of the permanent magnetic slide 8 .

[0027] The transparent glass sliding door 2 is internally provided with lifting and adjusting push rods 5 which are fitted and slidably connected. The upper and lower ends of the lifting and adjusting push rods 5 are hinged to the two ends of the second permanent magnet 4. By adjusting the extension and retraction of the lifting and adjusting push rods 5, the height of the second permanent magnet 4 inside the limit lifting opening 10 can be adjusted.

[0028] The lifting and adjusting push rod 5 is located in the middle of the transparent glass sliding door 2 and is connected with mutually staggered tooth plates 11, and the inner wall of the tooth plate 11 is connected with a tooth block 12. A limit adjustment rotating rod 6 is passed through the tooth plates 11 and meshes with the tooth block 12. By rotating the limit adjustment rotating rod 6, an upward and downward thrust can be applied to the tooth block 12 to drive the lifting and adjusting push rod 5 to drive the second permanent magnet 4 to rise and fall.

[0029] The limit adjustment rotating rod 6 includes a gear rod 13 inside, which is meshed with the gear block 12 and is used to drive the gear plate 11 to rise and fall. A locking push spring 14 is passed through the inner side of the gear rod 13, and a limit tube 15 is provided on the outer side of the locking push spring 14. The outer wall of the limit tube 15 slides on the inner side of the gear rod 13. At the same time, one end of the limit tube 15 is fixedly connected to the inside of the transparent glass sliding door 2, so as to limit and fix the rotation position of the limit adjustment rotating rod 6.

[0030] A locking tooth piece 16 is fixed to the end of the tooth rod 13 away from the limit tube 15, and the locking tooth piece 16 is embedded and connected with the transparent glass sliding door 2. When the limit adjustment rotating rod 6 is adjusted and rotated, the locking tooth piece 16 can be driven to separate from the transparent glass sliding door 2 by pressing, thereby realizing the rotation of the limit adjustment rotating rod 6. When the adjustment is completed, as the locking push spring 14 pushes, the locking tooth piece 16 will be pushed and locked with the transparent glass sliding door 2, thereby completing the locking of the limit adjustment rotating rod 6.

[0031] Usage process:

[0032] When installing the transparent glass sliding door 2, turn the limit adjustment rod 6 to completely store the second permanent magnet 4 inside the limit lifting port 10. At this time, the transparent glass sliding door 2 can be placed in the refrigerator 1 at the position where it needs to be installed. After the installation is completed, the transparent glass sliding door 2 will have a gap with the installation position of the refrigerator 1. Turn the limit adjustment rod 6 to push the second permanent magnet 4 out. The up and down movement of the second permanent magnet 4 can be used to complete the sealing of the connection between the transparent glass sliding door 2 and the refrigerator 1. At the same time, the gap between the second permanent magnet 4 and the refrigerator 1 can also be adjusted according to its own needs to ensure the sliding effect.
