In order to store food in a more orderly manner and without interfering with each other, people have made storage boxes for storing food. There are many types of storage boxes available. Some storage boxes are equipped with timers for recording the storage time of food, thereby confirming the freshness of the food.

[0003] After searching, for example, Chinese patent CN218821243U discloses a novel refrigerator storage box with adjustable space. By setting a glass baffle, a first connecting member, a slider, a first vertical baffle, a second vertical baffle, an extruded aluminum member, a second connecting member, a sliding frame, and a housing, the device can be installed in the refrigerator through an axis for use. The position of the glass baffle facilitates the adjustment of the space in the refrigerator storage box, which saves labor and greatly improves the use efficiency.

[0004] However, the device can only adjust the internal space of the storage box and cannot actually increase the storage capacity. When a large number of items need to be stored, multiple storage boxes need to be placed at one time for storage, which is inconvenient to use and lacks applicability. Therefore, we urgently need to provide a refrigerator storage box with space adjustment.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0024] The following is combined with Figure 1-5 This application is described in further detail.

[0025] The present application embodiment discloses a space-adjustable refrigerator storage box, referring to Figure 1-Figure 5 , including a storage box body 1, a movable shell 2 is arranged on the outside of the storage box body 1, a plurality of plug-in blocks 5 are evenly fixedly installed on the inner wall of the movable shell 2, a plurality of slots 6 are evenly opened on the outer surface membrane of the storage box body 1, the movable shell 2 is connected to the inner part of the slot 6 by the plug-in blocks 5, and the stability of the movable shell 2 when adjusted up and down is improved by the cooperation of the plug-in blocks 5 and the slot 6, rectangular grooves 7 are symmetrically opened at both ends of the inner wall of the movable shell 2, a rack plate 8 is fixedly installed on the inner surface of the rectangular groove 7, two knobs 9 are symmetrically arranged on the upper end of the inner wall of the storage box body 1, and ratchets 10 are fixedly installed on the inner sides of the two knobs 9.

[0026] Reference Figure 3 A transmission rod 11 is fixedly installed on the inner end of the ratchet 10, and the inner end of the transmission rod 11 penetrates the storage box body 1 and is fixedly connected with a gear 12. The gear 12 is arranged on the inner side of the rectangular groove 7 and the side of the gear 12 is meshed and connected with the outer surface of the rack plate 8. At the same time, when the two knobs 9 are turned, the transmission rod 11 is driven to rotate inside the upper end of the storage box body 1, driving the gear 12 on the inner side of the rectangular groove 7 to rotate. Under the action of the gear 12 and the rack plate 8, the movable shell 2 is continuously raised, thereby increasing the storage capacity of the device and improving applicability.

[0027] Reference Figure 3-Figure 4Two fixing seats 14 are symmetrically installed on the upper end of the inner wall of the storage box body 1. The two fixing seats 14 are respectively arranged at the bottom of the two ratchet wheels 10. The inner sides of the fixing seats 14 are movably connected with movable push rods 15. A limit plate is installed in the middle of the outer surface of the movable push rod 15. A return spring 16 is arranged on the outside of the movable push rod 15. The top of the return spring 16 is fixedly installed on the bottom of the limit plate and the bottom of the return spring 16 is fixedly installed on the inner side of the fixing seat 14. The knob 9 rotates and drives the ratchet 10 to rotate at the same time. When the movable shell 2 is adjusted to a suitable position and stops rotating, the movable push rod 15 on the inner side of the fixing seat 14 is pushed upward to the side of the ratchet wheel 10 by the return spring 16, thereby blocking the reverse rotation of the ratchet wheel 10, preventing the movable shell 2 from sliding down due to the influence of gravity, and enhancing stability.

[0028] Reference Figure 1-Figure 2 The upper end of the movable shell 2 is movably connected with a top cover 3, and a box buckle 4 is fixedly installed on the upper end of the front surface of the movable shell 2. A plurality of connecting grooves 17 are evenly opened on the inner surface of the storage box body 1, and two partition plates 18 are arranged on the inner side of the storage box body 1. The two ends of the two partition plates 18 are respectively plugged and connected with the inner sides of the connecting grooves 17. By opening a plurality of connecting grooves 17 on the inner side of the storage box body 1, users can install any number of partition plates 18 according to actual needs, which is convenient for separating the internal space of the storage box body 1, which is beneficial for classifying and storing items, and further enhancing the practicality of the device.

[0029] The implementation principle of a space-adjustable refrigerator storage box in the embodiment of the present application is as follows: when using the device, when the internal space of the storage box main body 1 is insufficient, the two knobs 9 can be rotated to drive the transmission rod 11 to rotate, driving the gear 12 inside the rectangular groove 7 to rotate, and the movable shell 2 is continuously raised under the action of the gear 12 and the rack plate 8, thereby increasing the storage capacity of the storage box, and the ratchet 10 is synchronously rotated while the knob 9 is rotated, and when the ratchet 10 rotates, the movable push rod 15 is continuously driven to reciprocate up and down. When the movable shell 2 is adjusted to a suitable position, the movable push rod 15 inside the fixing seat 14 is pushed by the reset spring 16 to clamp the reverse rotation of the ratchet 10, thereby fixing the position of the movable shell 2. When the movable shell 2 needs to be reset, the two movable push rods 15 are pulled downward to release the limit on the ratchet 10, and then the movable shell 2 is affected by gravity and naturally falls to its original position.
