DETAILED DESCRIPTION

[0019] The technical scheme in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] Reference Figures 1-4The utility model relates to a packing box with fresh -keeping effect, including box 1 and top board 4, the upper end of box 1 is equipped with the back -shaped groove, and top board 4 places in back -shaped groove, and the lower end of box 1 is fixedly connected with a plurality of fold support plate 2, and the upper end of box 1 is equipped with a plurality of fold grooves 3, so that subsequent when stacking, a plurality of fold support plate 2 can be inserted in a plurality of fold grooves 3, and the stability after stacking is stronger;

[0021] Wherein, further include limiting mechanism, limiting mechanism is used for limiting top board 4, limiting mechanism includes the rectangular groove that is set up on the inner wall of back -shaped groove both sides symmetry, two rectangular grooves are all slidably connected with connecting plate 11, the opposite side of two connecting plate 11 is all fixedly connected with wedge block 12, the opposite side of two connecting plate 11 is all through spring 15 and the inner wall of corresponding rectangular groove elastically connected, the both sides of top board 4 are all equipped with limiting slot 13, the inner top of two rectangular grooves is all equipped with strip mouth 10, the upper end of two connecting plate 11 all penetrates strip mouth 10, the opposite side of two strip mouth 10 is all embedded with permanent magnet 14, two connecting plate 11 are all iron plate, subsequent when disassembling, just need to be stirred to two connecting plate 11 to the amplitude that can be attracted by permanent magnet 14 can carry out disassembling operation;

[0022] Wherein, further include ice bag storage mechanism, ice bag storage mechanism is used for placing ice bag, and ice bag storage mechanism includes the sliding slot 5 that is equipped in the upper end of top board 4, and the lower end of top board 4 is fixedly connected with back -shaped frame 16, and the inner side of back -shaped frame 16 is provided with the breathable mesh 8 that can slide up and down, and the upper end of breathable mesh 8 is fixedly connected with two connecting rods 9 symmetry, and the upper end of two connecting rods 9 is commonly fixedly connected with sliding plate 6, and the upper end of sliding plate 6 is fixedly connected with handle, and sliding plate 6 is slidably connected with the inner wall of sliding slot 5, and the left and right two side walls of back -shaped frame 16 are all equipped with guide slot 17, and the upper and lower ends of guide slot 17 are not all through back -shaped frame 16, so that when the breathable mesh 8 moves down or moves up, there is a minimum height and maximum height, and the both sides of breathable mesh 8 are all fixedly connected with guide block 18, and two guide blocks 18 are all located in guide slot 17, and are slidably connected.

[0023] In the utility model, when installing top board 4, only need to press top board 4 to back -shaped groove, top board 4 will first resist two wedge blocks 12 opposite movement, and compress spring 15 through connecting plate 11, when limiting slot 13 corresponds with wedge block 12, under the elastic action of spring 15, wedge block 12 is inserted into limiting slot 13, completes limiting, in this process, the displacement amplitude of wedge block 12 is small, and the magnetic attraction of the most close permanent magnet 14 is also not too big, when disassembling subsequently, the two connecting plate 11 contact permanent magnet 14, the magnetic attraction is great at this time, and the elastic force of spring 15 is not enough to support its return at this position, so that top board 4 can be removed;

[0024] The upper end of the air-permeable net 8 is placed with an ice bag, so that the cold air generated by the ice bag moves downward, continuously generates descending cold air, and makes the temperature of the whole interior relatively uniform compared with the ice bag placed at the bottom. When the ice bag needs to be replaced, the sliding plate 6 is only pulled to move upward, the air-permeable net 8 is driven to move upward through the connecting rod 9, the ice bag on the air-permeable net 8 is taken off, a new ice bag is put in, and then the hand is released.
