Two handle grooves 4 are provided on the partition 3, and a control panel 5 is suspended in the handle groove 4. Buffer pads 14 are fixedly provided on the upper and lower side walls of the partition 3. When bumps occur during transportation, the buffering effect of the buffer pads 14 can prevent fruits and vegetables from being damaged by strong up and down vibrations. Several air holes 16 are provided on the partition 3 and the buffer pad 14. Through the ventilation effect of the air holes 16, the temperature of each layer of space separated by the several partitions 3 in the box body 1 can be kept consistent. Several No. 1 limit slots 6 are equidistantly provided on the front and back sides of the left and right inner walls of the box body 1;

[0029] Gear 7, there are several gears 7, which are rotatably connected to several partitions 3 through shafts and bearings. The front and rear sides of the gear 7 are meshed with gear rods 8. The left and right sides of the partition 3 are movably provided with a No. 1 limit frame 9. One end of the gear rod 8 is fixedly connected to the No. 1 limit frame 9. The two ends of the No. 1 limit frame 9 pass through the partition 3 and are inserted into the No. 1 limit groove 6;

[0030] No. 1 spring 10, there are several No. 1 springs 10, which are respectively fixedly arranged at the other end of several gear rods 8, and one end of the No. 1 spring 10 is fixedly connected to the No. 1 limit frame 9, and a reinforcing rod 13 is fixedly provided on the No. 1 limit frame 9, and the reinforcing rod 13 is movably inserted in the No. 1 spring 10, and one end of the reinforcing rod 13 is movably inserted in the gear rod 8, and the reinforcing rod 13 can realize the movable connection between the No. 1 limit frames 9 on the left and right sides, provide force sharing in the middle of the partition 3, and improve the force bearing performance of the partition 3. A secondary limiting mechanism 11 connected to the No. 1 limit frame 9 is provided in the partition 3, and two connecting rods 12 are fixedly provided on the side wall of the control panel 5. One end of the connecting rod 12 is movably inserted in the partition 3 and fixedly connected to the No. 1 limit frame 9;

[0031] The secondary limiting mechanism 11 includes:

[0032] The second limiting frame 11-1 is two and is movably arranged on the front and rear sides of the partition 3. A number of second limiting slots 15 are evenly spaced on the left and right sides of the front and rear inner walls of the box body 1. The ends of the second limiting frame 11-1 pass through the partition 3 and are inserted into the second limiting slots 15;

[0033] No. 2 spring 11-2, there are four No. 2 springs 11-2, which are fixedly arranged on two No. 2 limit frames 11-1 respectively, and one end of the No. 2 spring 11-2 is connected to the inner wall of the partition 3;

[0034] There are four No. 1 wedge blocks 11-3, which are fixed on the left and right sides of the two No. 2 limit frames 11-1 respectively. Two No. 2 wedge blocks 11-4 are fixed on the No. 1 limit frame 9. The No. 1 wedge block 11-3 and the inclined side walls of the No. 2 wedge block 11-4 are movably contacted with each other.

[0035] When using the present invention, fruits and vegetables are placed in the box body 1, and then the hand is passed through the handle groove 4 and the control panel 5 is pushed. The control panel 5 drives the No. 1 limiting frame 9 to move toward the middle direction of the partition 3, so that the end of the No. 1 limiting frame 9 is disengaged from the No. 1 limiting groove 6 and enters the partition 3. At the same time, the No. 1 limiting frame 9 will drive the No. 2 wedge block 11-4 to move closer to the No. 2 limiting frame 11-1, so that the No. 1 wedge block 11-3 is squeezed by the No. 2 wedge block 11-4 and drives the No. 2 limiting frame 11-1 to move toward the middle direction of the partition 3 and compress the No. 2 spring 11-2. At this time, the end of the No. 2 limiting frame 11-1 is disengaged from the No. 2 limiting groove 15 and enters the partition 3. During the movement of the No. 1 limiting frame 9, the gear 7 and the gear rod 8 can cooperate to ensure the synchronous movement of the No. 1 limiting frames 9 on both sides. And compress the No. 1 spring 10, then the partition 3 can be placed in the box body 1. After the partition 3 conflicts with the fruits and vegetables, the control board 5 can be loosened. At this time, the No. 1 spring 10 resets and extends to move the No. 1 limit frames 9 on both sides synchronously in opposite directions, so that the end of the No. 1 limit frame 9 is inserted into the No. 1 limit groove 6, thereby fixing the partition 3 in the box body 1. At the same time, the No. 2 spring 11-2 will also reset and extend to push the No. 2 limit frame 11-1, so that the end of the No. 2 limit frame 11-1 is inserted into the No. 2 limit groove 15, thereby increasing the limit of the partition 3 in the box body 1, and then the fruits and vegetables can continue to be placed on the partition 3 in the box body 1 to realize the separation of fruits and vegetables in the box body 1, and the weight of the fruits and vegetables placed above the partition 3 can be borne by the partition 3, No. 1 limit frame 9 and No. 2 limit frame 11-1, to avoid squeezing the fruits and vegetables in the lower layer.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. The interior space of the box body 1 can be divided by the partition 3. The control board 5, gear 7, gear rod 8, No. 1 limit frame 9, No. 1 spring 10 and connecting rod 12 cooperate to achieve the fixation of the partition 3 at any height in the box body 1. This can prevent the fruits and vegetables above the partition 3 in the box body 1 from squeezing the fruits and vegetables below the partition 3, and fully reduce the damage rate of fruits and vegetables during transportation;

[0038] 2. Through the cooperation of the secondary limiting mechanism 11, the secondary limiting of the partition 3 in the box body 1 can be achieved, so that the partition 3 is fixed in the box body 1 more firmly.

[0039] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
