TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator storage rack, in particular to a novel modular refrigerator detachable storage rack structure. BACKGROUND

[0002] At present, the common refrigerator storage rack on the market is mostly fixed structure, and its size and installation position cannot be adjusted once determined. This fixed design has many limitations: on the one hand, the space utilization is low. Since the width and height of the storage rack are fixed, it cannot be flexibly adapted to the specifications of the stored goods. For goods with large volume difference, either they cannot be stored due to insufficient space, or they are wasted due to redundant space, especially in commercial refrigerators, it is difficult to meet the diversified storage needs; on the other hand, it is difficult to maintain and disassemble. The traditional storage rack is rigidly connected to the refrigerator body. When the internal components of the refrigerator need to be repaired or the storage rack itself is damaged, all goods on the rack need to be emptied first, and then the fixed structure is removed by tools, which is cumbersome and time-consuming. If the goods are stacked full, the removal process may also cause damage to the goods, increasing the maintenance cost and operation difficulty. Based on this, a novel modular refrigerator detachable storage rack structure is invented to solve the above problems. SUMMARY

[0005] As a preferred technical scheme of the present application, the folding device comprises a support frame, the support frame is fixedly connected with a lifting device at the bottom, the support frame is fixedly connected with a connecting plate at the top on both sides of the groove, three folding plates are movably connected inside the two connecting plates, and first sliding wheels are fixedly connected to both ends of the three folding plates.

[0006] In a preferred embodiment of the present invention, the outer surfaces of the three first sliding wheels are respectively connected to grooved circular blocks, and the centers of the three grooved circular blocks are fixedly connected to a rotating column. The outer surface of the bottom end of the rotating column is fixedly connected to a circular base, and the outer surface of the circular base is movably connected to the top of the groove at one end of the support frame. A spring is fixedly connected to one end of the bottom of the circular base, and a movable block is correspondingly connected to the protruding part at the bottom of the spring, and the center of the top of the movable block is movably connected to the bottom of the rotating column.

[0007] As a preferred embodiment of the present invention, the push-pull device includes two sliding rails, each of which is fixedly connected to a rack on its inner side, and each of which is meshed with a gear on its outer surface. Each of which is movably connected to a first fixed rod at its center.

[0008] As a preferred embodiment of the present invention, two first rollers are movably connected to the outer grooves of the two sliding tracks, and a second fixed rod is movably connected to the top center of each of the four first rollers. A base plate is connected to the top of the two first fixed rods and the four second fixed rods respectively, and a lifting device is fixedly connected to the top of the base plate.

[0009] As a preferred embodiment of the present invention, the lifting device includes four lifting columns, the bottom of the four lifting columns is fixedly connected to the top of the base plate, and the top is connected to both ends of the bottom of the support frame. Two of the lifting columns are connected to a cylinder at their center, and a push block is fixedly connected to the output shaft end of the cylinder. A concave plate is movably connected to the bottom of the push block.

[0010] As a preferred embodiment of the present invention, both sides of the push block are fixedly connected with hollow plates, and two second rollers are connected to the hollow ends of the two hollow plates respectively. The outer surfaces of the four second rollers are movably connected to the top protrusion of the push block, and two T-shaped blocks are movably connected to the center of the four second rollers. The tops of the two T-shaped blocks are fixedly connected to the bottom of the support frame.

[0011] Compared with the prior art, the beneficial effects of the present invention are: (1) A novel modular refrigerator detachable storage rack structure, by setting first sliding wheels on both sides of three folding plates, the top outer surfaces of the three first sliding wheels can be used to roll and cooperate on the top of the grooved round blocks. During the movement, the three grooved round blocks will align their different shaped grooves with the first sliding wheels. In this way, the first sliding wheels can drive the folding plates fixedly connected at the bottom to flip to a parallel state during the movement, thereby adjusting different widths inside the refrigerator body to place items.

[0012] (2) A novel modular refrigerator detachable storage rack structure, by correspondingly setting a spring at the groove on the top of the movable block, allows the protruding part at the bottom of the spring to match the groove of the movable block. When the rotating column rotates under the action of external driving force, it will synchronously drive the rotation of the circular base fixedly connected to its bottom outer surface.

After locking, the rotating column can quickly adjust the movement direction of the three grooved circular blocks fixedly connected to its top outer surface, so that the different grooves of the three grooved circular blocks can respectively match the outer surface of the first sliding wheel.

[0013] (3) A novel modular refrigerator detachable storage rack structure, by setting gears on the outer surface of the rack, when the gears reciprocate along the rack, can drive the first fixed rod connected to its center to move synchronously. At this time, the two second sliding wheels that are engaged with the groove of the sliding track fixedly connected to the rear end of the rack roll together, thereby driving the second fixed rod connected to its center top to move synchronously in the same direction. During this process, the first fixed rod and the second fixed rod will jointly drive the bottom plate connected to the top to move to the outside of the refrigerator body, and finally move the lifting device connected to the top of the bottom plate out of the refrigerator body.

[0014] (4) A novel modular refrigerator detachable storage rack structure, by setting a push block at the output shaft end of the cylinder, the push block can slide back and forth in the groove at the top of the concave plate under the driving action of the cylinder. During the movement, the concave plate will abut the highest point against the outer surface of the third sliding wheel along its movement direction. At the same time, the protruding parts at both ends of the third sliding wheel will slide in the hollow part of the hollow plate to ensure that the movement is along the preset trajectory. When the third sliding wheel reaches the highest point, the T-shaped block connected in its center will drive the support frame fixedly connected at the top to move upward, thereby increasing the adjustment range of the rising height of the support frame for subsequent disassembly operations.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figures 1-2 A novel modular refrigerator with a detachable storage rack structure is disclosed. The structure includes a refrigerator body 1, with a storage device 2 connected to a corresponding open section inside the refrigerator body 1. The storage device 2 can remove materials stored on top of it from the refrigerator body 1 for subsequent maintenance or disassembly. The storage device 2 includes a folding device 21, a push-pull device 22, and a lifting device 23. The folding device 21 adjusts its width by folding and flipping to accommodate different storage spaces and increase storage capacity. The push-pull device 22 moves the corresponding lifting device 23 at its top horizontally out of the refrigerator body 1 and works in conjunction with the lifting device 23. The lifting device 23 adjusts its height vertically and moves the folding device 21 at its top synchronously, facilitating subsequent disassembly.

[0019] Example 2: Based on Example 1, as follows Figures 3-8As shown, the folding device 21 includes a support frame 211. A lifting device 23 is provided at the bottom of the support frame 211, and the bottom of the support frame 211 is fixedly connected to the top of the lifting device 23. Connecting plates 212 are provided on both sides of the top of the groove of the support frame 211, and the top two sides of the groove of the support frame 211 are fixedly connected to the bottom of the connecting plates 212. Three folding plates 213 are provided on the inner side of the two connecting plates 212, and the inner side of the two connecting plates 212 is movably connected to the two sides of the three folding plates 213. By providing first sliding wheels 214 on both sides of the three folding plates 213, the outer surface of the top of the three first sliding wheels 214 can roll and cooperate on the top of the grooved round block 215. During the movement, the three grooved round blocks 215 will align their different shaped grooves with the first sliding wheels 214. In this way, the first sliding wheels 214 can drive the folding plates 213 fixedly connected at the bottom to flip to a parallel state during the movement, thereby adjusting different widths inside the freezer body 1 to place items. Each of the three folding plates 213 has a first sliding wheel 214 at one end on both sides, and each of the three folding plates 213 is fixedly connected to the bottom of the first sliding wheel 214 at one end on both sides.

[0020] Each of the three first sliding wheels 214 has a grooved circular block 215 on its top outer surface, and the top outer surface of each of the three first sliding wheels 214 is correspondingly connected to the top of the grooved circular block 215. A rotating column 216 is provided at the center of each of the three grooved circular blocks 215, and the center of each of the three grooved circular blocks 215 is fixedly connected to the outer surface of the rotating column 216. A circular base 217 is provided on the bottom outer surface of the rotating column 216, and the bottom outer surface of the rotating column 216 is fixedly connected to the top of the circular base 217. The outer surface of the circular base 217 is movably connected to the top of the groove at one end of the support frame 211. A spring 218 is provided at one bottom end of the circular base 217. Furthermore, one end of the circular base 217 is fixedly connected to the top of the spring 218. The bottom protrusion of the spring 218 is provided with a movable block 219. By correspondingly setting the spring 218 at the groove on the top of the movable block 219, the bottom protrusion of the spring 218 can be adapted to the groove of the movable block 219. When the rotating column 216 rotates under the action of external driving force, it will synchronously drive the circular base 217 fixedly connected to its bottom outer surface to rotate. At this time, the spring 218 fixedly connected to one end of the bottom of the circular base 217 will move together to the groove on the top of the movable block 219, so that the spring 218 in a non-compressed state can be positioned in the groove, achieving locking and fixing. After locking, the rotating column 216 can quickly adjust the movement direction of the three grooved circular blocks 215 fixedly connected to its top outer surface, so that the different grooves of the three grooved circular blocks 215 can respectively cooperate with the outer surface of the first sliding wheel 214. Furthermore, the protruding part at the bottom of the spring 218 is connected to the groove at the top of the movable block 219, and the center at the top of the movable block 219 is movably connected to the bottom of the rotating column 216.

[0021] The push-pull device 22 includes two sliding rails 221. Each sliding rail 221 has a rack 222 on its inner side, and the inner side of each sliding rail 221 is fixedly connected to the rear end of the rack 222. Each rack 222 has a gear 223 on its outer surface, and the outer surface of each rack 222 meshes with the outer surface of the gear 223. Each gear 223 has a first fixing rod 224 at its center, and the center of each gear 223 is movably connected to the bottom of the first fixing rod 224.

[0022] Two second sliding wheels 225 are provided at the outer grooves of both sliding tracks 221, and the outer grooves of both sliding tracks 221 are movably connected to the outer surfaces of the two second sliding wheels 225. A second fixing rod 226 is provided at the top center of each of the four second sliding wheels 225, and the top center of each of the four second sliding wheels 225 is movably connected to the bottom of the second fixing rod 226. A base plate 227 is provided at the top of the two first fixing rods 224 and the four second fixing rods 226, and the tops of the two first fixing rods 224 and the four second fixing rods 226 are correspondingly connected to the bottom of the base plate 227. A gear 223 is provided on the outer surface of the rack 222. When the gear 223 reciprocates along the rack 222, it can drive the first fixing rod 224, which is movably connected at its center, to move synchronously. At this time, the two second sliding wheels 225, which are engaged at the grooves of the sliding track 221 fixed to the rear end of the rack 222, roll together, thereby driving the second fixing rod 226, which is movably connected at its center, to move synchronously in the same direction. During this process, the first fixing rod 224 and the second fixing rod 226 will jointly drive the bottom plate 227 connected to the top to move outwards towards the outside of the freezer body 1, ultimately causing the lifting device 23 connected to the top of the bottom plate 227 to move out of the freezer body 1 for subsequent height adjustment operations. The bottom plate 227 is provided with a lifting device 23, and the top of the bottom plate 227 is fixedly connected to the bottom of the lifting device 23.

[0023] The lifting device 23 includes four lifting columns 231. The bottom of the four lifting columns 231 is fixedly connected to the top of the base plate 227, and the top is connected to both ends of the bottom of the support frame 211. Two of the lifting columns 231 are provided with cylinders 232 at their centers, and the centers of the two lifting columns 231 are correspondingly connected to the outer side of the cylinders 232. The output shaft end of the cylinder 232 is provided with a push block 233, and the output shaft end of the cylinder 232 is fixedly connected to the top of the push block 233. The bottom of the push block 233 is provided with a concave plate 234, and the bottom of the push block 233 is movably connected to the groove at the top of the concave plate 234.

[0024] Both sides of the push block 233 are provided with hollow plates 235, and both sides of the push block 233 are fixedly connected to the inner bottom of the hollow plates 235. Two third sliding wheels 236 are provided at the hollow ends of both hollow plates 235, and the hollow ends of both hollow plates 235 are correspondingly connected to the protruding parts of the two third sliding wheels 236. The outer surfaces of both ends of the four third sliding wheels 236 are movably connected to the protruding parts at the top of the push block 233. Two T-shaped blocks 237 are provided at the center of the four third sliding wheels 236. The center of the third sliding wheel 236 is movably connected to the bottom of the two T-blocks 237. A push block 233 is provided at the output shaft end of the cylinder 232. Driven by the cylinder 232, the push block 233 can slide back and forth within the groove at the top of the concave plate 234. During movement, the concave plate 234 will bring its highest point to abut against the outer surface of the third sliding wheel 236 along its direction of movement. Simultaneously, the protruding parts at both ends of the third sliding wheel 236 will slide at the hollowed-out area of ​​the hollow plate 235, ensuring that the movement follows a preset trajectory. When the third sliding wheel 236 reaches its highest point, the T-block 237 connected to its center will drive the support frame 211 fixedly connected at the top to move upward. During this process, the lifting columns 231 at both ends will move upward synchronously with the T-block 237, effectively dispersing the weight on the top and increasing the adjustment range of the support frame 211's rising height for subsequent disassembly. The tops of the two T-blocks 237 are fixedly connected to the bottom of the support frame 211.

[0025] The working principle of this invention is as follows: First, the rotating column 216 in the folding device 21 will rotate under the drive of external power. When the rotating column 216 rotates, it will drive the three grooved round blocks 215 fixedly connected to its outer surface to rotate synchronously. This will cause the grooves of different shapes on the surface of the grooved round blocks 215 to cooperate with the top outer surface of the first sliding wheel 214 connected to one side of the folding plate 213 in sequence. Under the guidance of the groove trajectory, the first sliding wheel 214 will be displaced and drive the folding plate 213 to flip around the inner support point of the connecting plate 212. At the same time, as the rotating column 216 rotates, the circular base 217 will allow the spring 218 fixedly connected to the bottom to move to the groove on the top of the movable block 219 and engage and fix it, thereby stabilizing the folding plate 213 at the required width position and realizing flexible adjustment of storage space. When the storage rack needs to be moved out of the freezer body 1, the push-pull device 22 starts to work. The push-pull device 22 includes a gear 223. The gear 223 also rolls back and forth along the outer surface of the rack 222 under the drive of an external motor. During the movement, it drives the first fixed rod 224, which is movably connected in the center, to move horizontally together. At the same time, the second sliding wheel 225, which is movably connected in the groove on the outer side of the sliding track 221, also rolls along with it, driving the second fixed rod 226, which is movably connected at the top, to move synchronously. Under the combined action of the first fixed rod 224 and the second fixed rod 226, the bottom plate 227 connected at the top can be quickly moved horizontally to the outside of the freezer, thereby moving the lifting device 23 and the folding device 21 connected at the top out of the freezer together. The lifting device 23 includes a cylinder 232, which drives a push block 233 fixedly connected to the output shaft to slide back and forth in the groove at the top of the concave plate 234. During the movement, the highest point of the concave plate 234 abuts against the outer surface of the third sliding wheel 236. At this time, the protruding parts at both ends of the third sliding wheel 236 also move along the hollowed-out area of ​​the hollow plate 235 according to a preset trajectory. When the third sliding wheel 236 reaches the highest point, the T-shaped block 237 connected to its center will quickly drive the support frame 211 to move upward. At the same time, the corresponding lifting columns 231 at both ends will also move upward synchronously to disperse the top gravity, thereby realizing the height adjustment of the folding device 21. Through the orderly cooperation of these three devices, the width adjustment, removal from the freezer, and height adjustment of the storage rack are completed, ultimately achieving the functions of flexible storage and convenient disassembly and maintenance.
