[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] Example: See Figure 1-4 The utility model provides a technical solution: a cabinet with a storage rack lifting structure, including a bottom plate 1, the top of the bottom plate 1 is fixedly connected to the cabinet body 11, the top of the cabinet body 11 is fixedly connected to the top plate 12, the top of the bottom plate 1 is fixedly connected to two partitions 13, the bottom of the bottom plate 1 is fixedly connected to four supporting legs 14, the top of the bottom plate 1 is rotatably connected to two front cylinders 2 and two rear cylinders 21, a storage plate 22 is slidably connected between the two partitions 13, both sides of the storage plate 22 are rotatably connected to the front rod 23 and the rear rod 24, the ends of the two front rods 23 away from the storage plate 22 pass through the side walls of the partition 13 and are rotatably connected to a movable bottom block 25, and a movable top block 26 is provided above the two movable bottom blocks 25, and the two movable bottom blocks 25 are rotatably connected to a sliding bottom block 27 on one side close to the front cylinder 2, and the two movable top blocks 26 are rotatably connected to a sliding top block 28 on the one side close to the rear cylinder 21.

[0021] A first connecting rod 3 is rotatably sleeved between the two rear rods 24 and the front rod 23, and a second connecting rod 31 is rotatably sleeved between the two rear rods 24 and the movable top block 26. By setting the first connecting rod 3 and the second connecting rod 31, under the connection action of the first connecting rod 3 and the second connecting rod 31, the two movable top blocks 26 drive the two rear rods 24 and the first connecting rod 3 to rotate around the two front rods 23 through the second connecting rod 31 on their outer sides.

[0022] The top ends of the two front cylinders 2 and the two rear cylinders 21 are fixedly connected with a transmission block 4, and a transmission belt 41 is connected between two adjacent transmission blocks 4. By setting the transmission belt 41, under the transmission action of the transmission belt 41, the four transmission blocks 4 drive the two front cylinders 2 and the two rear cylinders 21 to rotate on the top of the base plate 1.

[0023] A front groove 5, a rear groove 51 and a triangular groove 52 are provided on the outer side walls of the two partitions 13. The two front rods 23 pass through the partition 13 through the front groove 5, and the two rear rods 24 pass through the partition 13 through the rear groove 51. By setting the front groove 5, the rear groove 51 and the triangular groove 52, the front rod 23 is slidably connected to the partition 13 along the front groove 5, and the rear rod 24 is slidably connected to the partition 13 along the rear groove 51 and rotates around the front rod 23 inside the triangular groove 52.

[0024] A spiral slow groove 6 is provided on the outer wall of the two front tubes 2 and the two rear tubes 21, and a spiral fast groove 61 is provided on the outer wall of the two rear tubes 21. The two spiral fast grooves 61 are connected to the spiral slow groove 6. By setting the spiral slow groove 6 and the spiral fast groove 61, the height of the sliding bottom block 27 and the sliding top block 28 are adjusted, thereby controlling the position height and inclination angle of the storage plate 22.

[0025] Two pairs of card strips 7 are fixedly connected between the bottom plate 1 and the top plate 12. A card slot 71 is provided on one side of the two movable bottom blocks 25 and the two movable top blocks 26 close to the card strip 7. The two movable bottom blocks 25 and the two movable top blocks 26 are slidably connected to the card strip 7 through the card slot 71. By setting the card strip 7, the movable bottom block 25 and the movable top block 26 are limited, so that the movable bottom block 25 and the movable top block 26 are slidably connected to the card strip 7 through the card slot 71, preventing the sliding bottom block 27 and the sliding top block 28 from deviating.

[0026] Two drive motors 8 are fixedly connected to the top of the top plate 12. The output ends of the two drive motors 8 pass through the side walls of the top plate 12 and are fixedly connected to the transmission block 4. By setting the drive motor 8 and starting the drive motor 8, the drive motor 8 drives the transmission block 4 to rotate below the top plate 12 through the output end.

[0027] Working principle: by starting the two driving motors 8, the driving motor 8 drives the transmission block 4 to rotate under the top plate 12 through the output end, and under the transmission action of the transmission belt 41, the transmission block 4 drives the two front cylinders 2 and the two rear cylinders 21 to rotate on the top of the bottom plate 1, and the two front cylinders 2 and the two rear cylinders 21 drive the spiral slow groove 6 on their outer sides to rotate. Under the limiting action of the card strip 7, the spiral slow groove 6 drives the two moving bottom blocks 25 and the two moving top blocks 26 along the card strip 7 through the sliding bottom block 27 and the sliding top block 28 inside it. The two moving bottom blocks 25 drive the two front rods 23 to move upward. Under the connection action of the first connecting rod 3 and the second connecting rod 31, the two front rods 23 and the two moving top blocks 26 drive the two rear rods 24 to move upward through the first connecting rod 3 and the second connecting rod 31. The two front rods 23 and the two rear rods 24 drive the storage plate 22 to maintain a horizontal state and move upward. The two rear cylinders 21 continue to rotate, and the two rear cylinders 21 drive the spiral The slow groove 6 and the spiral fast groove 61 rotate, causing the two sliding top blocks 28 to slide along the two spiral slow grooves 6 and the two spiral fast grooves 61. The two spiral fast grooves 61 drive the two movable top blocks 26 to move rapidly upward along the card strip 7 through the sliding top blocks 28 therein. At the same time, the two spiral slow grooves 6 continue to drive the two movable bottom blocks 25 to move slowly upward along the card strip 7 through the sliding bottom blocks 27 therein, so that the distance between the two movable bottom blocks 25 and the two movable top blocks 26 becomes larger. Under the connection action of the first connecting rod 3 and the second connecting rod 31, the two movable top blocks 26 drive the two rear rods 24 and the first connecting rod 3 to rotate around the two front rods 23 through the second connecting rod 31 outside thereof. The two rear rods 24 drive the storage plate 22 to rotate ninety degrees around the two front rods 23, so that the top of the storage plate 22 is located at the opening of the cabinet body 11, expanding the user's cleaning operation space for the storage plate 22, thereby reducing the difficulty of cleaning the storage plate 22, and thus improving the user's use effect of the cabinet body 11.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
