The air holes 323 are all interconnected with the accommodating cavity 11. 1. Since the air cover 3 is located between the box body 1 and the cover body 2, and the box body 1 and the cover body 2 are detachably connected, the user cannot access the air cover 3 and the adjustment disk 32 when the cover body 2 is not removed from the box body 1. Therefore, the air cover 3 can be stably located in the box body 1 at this time; 2. Since the adjustment disk 32 is rotatably installed on the air cover 3 and the first air permeable area 321 and the second air permeable area 322 are provided on the adjustment disk 32, after the cover body 2 is removed from the box body 1, the coverage degree of the air holes 323 on the first air permeable area 321 and the second air permeable area 322 can be adjusted by rotating the adjustment disk 32. When each air hole 323 is covered by the adjustment disk 32 to different degrees, the air permeability of the items stored in the accommodating cavity 11 can be adjusted.

[0023] Among them, it also includes a plurality of first mating blocks 4 and second mating blocks 5, the adjustment disk 32 is located in the first ventilation area 321 and the second ventilation area 322, and is integrally formed with a first adjustment plate 326 and a second adjustment plate 327, the ventilation cover 3 is located on the rotation track of the first adjustment plate 326 and the second adjustment plate 327, and is respectively provided with a first adjustment track 324 and a second adjustment track 325, each of the first mating blocks 4 is located in the first adjustment track 324 and is arranged at intervals along the shape of the first adjustment track 324, each of the second mating blocks 5 is located in the second adjustment track 325 and is arranged at intervals along the shape of the second adjustment track 325, the first adjustment plate 326 is located in the first adjustment track 324 and is detachably connected to one of the first mating blocks 4 by bolts, snaps, etc., the second adjustment plate 327 is located in the second adjustment track 325 and is connected to one of the second mating blocks 5 by bolts , snap-on, etc., and since the air permeable cover 3 is provided with a plurality of first mating blocks 4 in the first adjustment track 324 and a plurality of second mating blocks 5 in the second adjustment track 325, the first adjustment plate 326 and the second adjustment plate 327 can be connected with the first mating block and the second mating block at the corresponding position after the position is determined by rotating the adjustment disk 32, and since the first adjustment plate 326 can be detachably connected to one of the first mating blocks 4 and the second adjustment plate 327 can be detachably connected to one of the second mating blocks 5, the first adjustment plate 326 is separated from the corresponding first mating block 4, the second adjustment plate 327 is separated from the corresponding second mating block 5 and connected to the other first mating block 4 and the second mating block 5, so as to realize the position adjustment and fixation of the adjustment disk 32, and then determine the position of the adjustment disk 32 on the air permeable cover 3 so that the adjustment disk 32 will not rotate at will.

[0024] Among them, each of the first mating plug-in blocks 4 includes a first limiting portion 41, a second limiting portion 42 and a deformation groove 43 located between the first limiting portion 41 and the second limiting portion 42, one end of the first limiting portion 41 and the second limiting portion 42 are both against the first adjustment plate 326, and the first adjustment plate 326 is provided with a first mating slot 3261 corresponding to the first mating plug-in block 4, and the shape and size of each of the second mating plug-in blocks 5 are the same as the shape and size of the first mating plug-in block 4, and when the position of the adjustment disk 32 located on the breathable cover 3 is rotated and confirmed, at this time, due to the existence of each deformation groove 43, by applying force to squeeze the first limiting portion 41 and the second limiting portion 42 toward the corresponding deformation groove 43, the first When the mating plug 4 enters the first mating slot 3261 and loses the force, the first limiting portion 41 and the second limiting portion 42 will move away from the deformation groove 43 and then resist the first adjustment plate 326, so that in the absence of external force, the positions of the first adjustment plate 326 and the second adjustment plate 327 of the adjustment disk 32 are determined, so that the adjustment disk 32 will not rotate easily. When the adjustment disk 32 needs to be rotated, the first limiting portion 41 and the second limiting portion 42 apply force toward the deformation groove 43 and then lift the two ends of the adjustment disk 32, so that the first adjustment plate 326 and the second adjustment plate 327 can cooperate with different first mating plugs 4 and second mating plugs 5, thereby completing the change and determination of the position of the adjustment disk 32.

[0025] Preferably, the first limiting portion 41 includes a first guide block 411, which is inclined from the deformation groove 43 side to the side away from the deformation groove 43 from top to bottom, and the second limiting portion 42 includes a second guide block 421, which is inclined from the deformation groove 43 side to the side away from the deformation groove 43 from top to bottom. Since the first guide block 411 and the second guide block 421 are both inclined, when the first adjustment plate 326 needs to be inserted into the first mating block 4 and the second adjustment plate 327 needs to be inserted into the second mating block 5, the first guide block 411 and the second guide block 421 first contact the first mating slot 3261. The inclination of the two makes the first limiting portion 41 and the second limiting portion 42 narrow at the top and wide at the bottom, so that the first mating block 4 can enter the first mating slot 3261 more smoothly to realize the position determination of the first adjustment plate 326 on the first adjustment rail 324.

[0026] In addition, a plurality of positioning blocks 6 are arranged around the box body 1, and the positioning portion 31 is provided with a first positioning slot 311 corresponding to each positioning block 6, and the cover body 2 is provided with a second positioning slot 21 corresponding to each positioning block 6. 1. Since each positioning block 6 after assembly is inserted into the corresponding first positioning slot 311 and second positioning slot 21, the arrangement of each positioning block 6 makes it impossible for the breathable cover 3 and the cover body 2 to rotate relative to the box body 1 and cannot be separated without the action of external force; 2. When the cover needs to be When the body 2 is removed from the box body 1, it is necessary to apply force to each side of the cover body 2 toward the side away from the accommodating chamber 11 so that each second positioning slot 21 is separated from the corresponding positioning plug 6 and then removed. At this time, the breathable cover 3 is still stably located on the box body 1, and the adjustment disk 32 can be rotated to change the air permeability of the box body 1. When force is applied to each side of the breathable cover 3 toward the side away from the accommodating chamber 11, each positioning plug 6 can be separated from the corresponding first positioning slot 311, and then the breathable cover 3 is removed from the box body 1.

Due to the shape of each positioning block 6, when each positioning block 6 is inserted into the first positioning slot 311 corresponding to the breathable cover 3 and the second positioning slot 21 of the cover body 2, each first positioning slot 311 and the second positioning slot 21 can first contact the other end of each positioning block 6 parallel to the right-angle surface, thereby more smoothly inserting the positioning block 6 into the corresponding first positioning slot 311 and the second positioning slot 21.

[0028] Among them, the cover body 2 is provided with a plurality of lower positioning posts 22 protruding downward, and the air permeable cover 3 is provided with upper positioning posts 33 corresponding to each lower positioning post 22, and each upper positioning post 33 is provided with an insertion groove 331 for inserting the corresponding lower positioning post 22. After the air permeable cover 3 is installed on the box body 1, that is, each positioning plug 6 is inserted into the corresponding first positioning insertion groove 331, when the cover body 2 falls downward on the air permeable cover 3, each lower positioning post 22 of the cover body 2 will fall into the insertion groove 331 of the corresponding upper positioning post 33 in the air permeable cover 3. At this time, the side panels of the cover body 2 are expanded outward, so that each positioning plug 6 can be inserted into the corresponding second positioning slot 21 to realize the position determination of the cover body 2 on the box body 1.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
