[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] like Figures 1 to 11 As shown, a horizontal island cabinet with assisted reset of a glass sliding door includes a cabinet body 1 and a glass sliding door 3. A guide rail 2 is provided on the cabinet body 1, and the glass sliding door 3 is slidably mounted on the guide rail 2. A damping return device 9 is provided on the glass sliding door 3. The damping return device 9 includes a base 9-1, a damping gas spring 9-2, and a limit hook 9-5. The limit hook 9-5 is connected to the damping gas spring 9-2. A positioning block 5 is provided on the cabinet body 1 to cooperate with the limit hook 9-5. When the glass sliding door 3 is closed and reaches the disengagement critical position, the limit hook 9-5 engages with the positioning block 5, and the damping gas spring 9-2 applies a pulling force to the glass sliding door 3 to keep the glass sliding door 3 tightly closed. When the glass sliding door 3 is opened and reaches the disengagement critical position, the limit hook 9-5 disengages from the positioning block 5.

[0027] In this utility model, when the glass sliding door 3 is in the closed state, the limit hook 9-5 is engaged with the positioning block 5, and the glass sliding door 3 is kept in a tightly closed state under the pulling force of the damping gas spring 9-2, so as to avoid the leakage of cold air and reduce the power consumption of the horizontal island cabinet. When the glass sliding door 3 is opened, before it reaches the disengagement critical position, the limiting hook 9-5 remains engaged with the positioning block 5. During the opening and movement of the glass sliding door 3, the damping gas spring 9-2 is continuously stretched and is in an energy storage state. When the glass sliding door 3 is opened a certain distance, it reaches the disengagement critical position. At this time, the damping gas spring 9-2 is stretched to its maximum state. At this position, the limiting hook 9-5 disengages from the positioning block 5. During the subsequent movement, the glass sliding door 3 can move freely without being affected by the damping return device 9. When the glass sliding door 3 is closed, when it moves to the disengagement critical position, the limiting hook 9-5 engages with the positioning block 5. Then, the damping gas spring 9-2 releases its elastic potential energy and applies a pulling force to the glass sliding door 3. Under the pulling force of the damping gas spring 9-2, the glass sliding door 3 automatically reaches the closed state.

[0028] Therefore, when consumers close the glass sliding door 3, even if the glass sliding door 3 is not completely closed, as long as the glass sliding door 3 exceeds the disengagement critical position during the closing process, the remaining closing process of the glass sliding door 3 can be automatically completed by the damping return device 9. Under the pulling force of the resistance gas spring, the glass sliding door 3 can be ensured to be completely closed, thereby avoiding the impact on the refrigeration effect of the goods due to the glass sliding door 3 not being completely closed, and also reducing the power consumption of the horizontal island cabinet.

[0029] like Figures 6 to 8 As shown, guide bosses 9-4 are provided on both sides of the base 9-1 of the damping return device 9. The guide bosses 9-4 include a horizontal section 9-4a, an inclined section 9-4b, and a vertical section 9-4c. The inclined section 9-4b is located at one end of the horizontal section 9-4a. A rotating shaft 9-5e is rotatably connected to the limiting hook 9-5. The rotating shaft 9-5e is connected to the telescopic rod on the damping gas spring 9-2. The two ends of the rotating shaft 9-5e are respectively provided with slots. The rotating shaft 9-5e is located between the guide bosses 9-4 on both sides. The horizontal section 9-4a on the guide bosses 9-4 is inserted into the slots. A first hook body 9 is provided on the limiting hook 9-5. -5a and the second hook body 9-5b, the first groove body and the second hook body 9-5b are arranged opposite to each other, and a groove area is formed between the first hook body 9-5a and the second hook body 9-5b; the limiting hook 9-5 is provided with a first protrusion 9-5c on both sides, and a second protrusion 9-5d is also provided on both sides; the guide boss 9-4 is sandwiched between the first protrusion 9-5c and the second protrusion 9-5d; when the first protrusion 9-5c and the second protrusion 9-5d pass through the inclined section 9-4b on the guide boss 9-4, the limiting hook 9-5 rotates relative to the rotating shaft 9-5e.

[0030] like Figure 9 As shown, when the glass sliding door 3 is in the closed state, the limit hook 9-5 is engaged with the positioning block 5. At this time, the limit hook 9-5 is in a horizontal state, and the positioning block 5 is engaged in the groove area on the limit hook 9-5. At this time, the telescopic rod of the damping gas spring 9-2 is in the retracted state, and the limit hook 9-5 is located at the position closest to the damping gas spring 9-2 (i.e., the first limit position). During the opening of the glass sliding door 3, as the glass sliding door 3 moves, the limiting hook 9-5 is pulled away from the damping gas spring 9-2. When the glass sliding door 3 moves to the disengagement critical position, the extension distance of the telescopic rod of the damping gas spring 9-2 reaches its maximum, and the limiting hook 9-5 is at the position furthest from the damping gas spring 9-2 (i.e., the second limit position). The limiting hook 9-5 also just moves to the inclined section 9-4b. When the limiting hook 9-5 moves at the inclined section 9-4b, the angle of the limiting hook 9-5 will change, and the end of the limiting hook 9-5 with the first hook body 9-5a will gradually tilt upward until it disengages from the positioning block 5. After the limiting hook 9-5 disengages from the positioning block 5, the limiting hook 9-5 maintains its relative position with the damping gas spring 9-2, so that the elastic potential energy of the damping gas spring 9-2 reaches its maximum. Figure 10 As shown, when the glass sliding door 3 passes the disengagement critical position, the glass sliding door 3 is opened, the limit hook 9-5 disengages from the positioning block 5, and the glass sliding door 3 is no longer constrained by the tension of the damping return device 9, allowing the glass sliding door 3 to move easily. Figure 11 As shown, during the closing process of the glass sliding door 3, when the glass sliding door 3 reaches the disengagement critical position, the second hook body 9-5b on the limiting hook 9-5 will collide with the positioning block 5. Under the action of the collision, the angle of the limiting hook 9-5 changes, and the limiting hook 9-5 returns from its original inclined state to the overall horizontal state, so that the positioning block 5 is stuck in the groove area between the first hook body 9-5a and the second hook body 9-5b, so that the limiting hook 9-5 and the positioning block 5 are fastened together. When the angle of the limiting hook 9-5 turns to the horizontal state, the limiting hook 9-5 will slide along the horizontal section 9-4a on the guide boss 9-4 under the pulling force of the damping gas spring 9-2. Under the pulling force of the damping gas spring 9-2, the glass sliding door 3 is pulled to move, so that the glass sliding door 3 reaches the closed state.

[0031] The base is provided with mounting holes 9-6, and the base is connected to the glass sliding door 3 through the mounting holes 9-6.

[0032] like Figure 7 As shown, the limiting hook 9-5 is provided with a first spring hook point 9-5f, and the base is provided with a second spring hook point 9-7. An auxiliary spring connects the first spring hook point 9-5f and the second spring hook point 9-7. The auxiliary spring... Figure 7Not shown in the drawing, the auxiliary spring is a helical spring. One end of the auxiliary spring is connected to the first spring hanging point 9-5f, and the other end of the auxiliary spring is connected to the second spring hanging point 9-7.

[0033] A fixing strip 6 is provided at the lower end of the glass sliding door 3. A roller is provided on the fixing strip 6, and the roller moves along the guide rail 2; a damping return device 9 is installed on the fixing strip 6.

[0034] like Figure 5 As shown, a refrigeration area is provided above the cabinet 1, and an insulated inner liner 15 is provided below the refrigeration area. A circulating cooling space is provided inside the insulated inner liner 15, and an evaporator 16 is provided in the circulating cooling space. A first air outlet 12, a first return air outlet 4, a second air outlet 14, and a second return air outlet 13 are provided between the circulating cooling space and the refrigeration area.

[0035] like Figure 3 As shown, the glass sliding door 3 is equipped with a crash block 7, and the crash block 7 is equipped with a flexible buffer component 8. The crash block 7 is used to reduce the impact force between the two glass sliding doors 3, and plays a good role in buffering and preventing collisions.

[0036] In this embodiment, the flexible buffer component 8 is made of rubber material.

[0037] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
