The curved surface of the middle section of the rotating shaft presses against the mounting plate, causing one end of the mounting plate to slide within the inner cavity of the fixing sleeve and compressing the spring. When the refrigerator door is released, the spring drives the mounting plate to return to its original position after the pressure is released, causing the refrigerator door to close automatically. In addition, when the rotating shaft returns to its original position, its protrusion presses against the movable push plate, causing the movable push plate to press against the buffer cylinder. In this way, the buffer cylinder cushions the spring's rebound force, thus achieving a buffered closing of the refrigerator door. Furthermore, the automatic reset also enhances the seal between the refrigerator door and the refrigerator. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a buffer hinge, including a base 1 and a top cover 2. A limiting block 13 and a limiting post 7 are fixedly connected to the inner cavity of the top cover 2. A mounting plate 5 is slidably sleeved on the surface of the limiting block 13. A buffer cylinder 9 is provided on the surface of the mounting plate 5, with one end of the buffer cylinder 9 abutting against the port of a fixed sleeve 8, and the output end of the buffer cylinder 9 abutting against one end of the mounting plate 5. The mounting plate 5 is located in the inner cavity of the top cover 2. The limiting post 7 is slidably sleeved in the inner cavity of the mounting plate 5, and a movable push plate 6 is slidably sleeved on the surface of the limiting post 7. The movable push plate 6 and the buffer cylinder 9 are slidably sleeved in the inner cavity of the base 1. The surface of the mounting plate 5 has an opening for placing the buffer cylinder 9. The base 1 has a slot, so the buffer cylinder 9 is limited in the slot. The inner cavity of the base 1 is provided with a movable push plate 6 and a sliding groove for the buffer cylinder 9. The sliding groove fits with the movable push plate 6 and the buffer cylinder 9. The base 1 and the top cover 2 cover each other. The movable push plate 6 fits against the surface of the mounting plate 5. The inner cavity of the top cover 2 is provided with a fixing sleeve 8. The inner cavity of the fixing sleeve 8 is provided with a spring 11. One end of the fixing sleeve 8 is threaded with a stop block 12. One end of the mounting plate 5 is slidably fitted into the inner cavity of the fixing sleeve 8 and abuts against the spring 11. One end of the limiting post 7 is rotatably fitted into the inner cavity of the base 1. The movable push plate 6 and the mounting plate 5 are limited by the limiting post 7, and the movable push plate 6 and the mounting plate 5 can slide.
[0024] Furthermore, the inner cavity of the top cover 2 and the base 1 is rotatably fitted with a rotating shaft 4, and the surface of the rotating shaft 4 is provided with a protrusion 10 and an arc-shaped surface 14. The protruding point of the protrusion 10 abuts against one end of the movable push plate 6, and the arc-shaped surface 14 in the middle section of the rotating shaft 4 abuts against one end of the mounting plate 5. One end of the rotating shaft 4 extends to the outside of the surface of the top cover 2 and is fixedly connected to a connector 3. The rotating shaft 4 is driven to rotate through the connector 3, thereby causing one end of the protrusion 10 to press the movable push plate 6 to move and press the buffer cylinder 9. At this time, the arc-shaped surface 14 in the middle section of the rotating shaft 4 will not contact the mounting plate 5.
[0025] When working or using, first install the connector 3 on the freezer door with screws, then install the base 1 and top cover 2 on the freezer. When the freezer door is rotated, the connector 3 will drive the rotating shaft 4 to rotate. The arc-shaped surface 14 in the middle of the rotating shaft 4 will press the mounting plate 5, causing the mounting plate 5 to slide under the limit of the limiting block 13 and the limiting post 7. One end of the mounting plate 5 will slide in the inner cavity of the fixing sleeve 8 and compress the spring 11. At this time, the protrusion 10 will not contact the push plate 6.
[0026] Therefore, when the refrigerator is left open, the spring 11 will rebound after the pressure is released, causing the mounting plate 5 to reset. The mounting plate 5 will then press the rotating shaft 4, causing the connecting piece 3 to reset as well, thus automatically closing the refrigerator door. In addition, when the rotating shaft 4 resets, its protrusion 10 will press the movable push plate 6, causing the movable push plate 6 to press the buffer cylinder 9. In this way, the buffer cylinder 9 will buffer and reduce the rebound force of the spring 11, thus achieving the problem of buffered closing of the refrigerator door. Furthermore, the automatic reset can also enhance the sealing between the refrigerator door and the refrigerator.
[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
