DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1 , Figure 2 and Figure 3An adjustable storage box device shown in the figure comprises an open first box 1 and an open second box 2, wherein the first box 1 covers the second box 2 to form a closed cavity, an adjustment device 3 is connected between the first box 1 and the second box 2, the adjustment device 3 comprises a rack mechanism 31 on the first box 1 and a locking mechanism 32 on the second box 2, the locking mechanism 32 comprises a supporting portion 321, a protruding portion 322 and a connecting member 323 connecting the protruding portion 322, and the connecting member 323 can move on the supporting portion 321;

[0028] The storage box device has a locking state and an adjustment state. When the storage box device is in the locking state, the protrusion 322 of the locking mechanism 32 is embedded in the tooth groove of the rack mechanism 31;

[0029] When the storage box device is in the adjustment state, the connecting piece 323 of the locking mechanism 32 is located on the supporting portion 321 , and the protruding portion 322 of the connecting piece is away from the rack mechanism 31 , so that the second box 2 can be adjusted on the first box 1 along the length direction of the rack mechanism 31 .

[0030] The first box body 1 is covered on the second box body 2 to form a closed cavity as a storage box device. At the same time, the first box body 1 can be moved on the second box body 2 through the adjustment device 3, so that the size of the cavity of the storage box device can be adjusted to facilitate accommodating items of different sizes. It has strong applicability and a wide range of applications. The locking mechanism 32 on the adjusting device 3 can move along the rack mechanism 31. When the locking mechanism 32 moves on the rack mechanism 31, the protrusion 322 on the locking mechanism 32 is connected to the connecting piece 323, and by supporting the connecting piece 323 on the supporting portion 321, the protrusion 322 is away from the rack mechanism 31, so that the locking mechanism 32 can be easily moved along the rack mechanism 31 to adjust the size of the inner cavity of the storage box device; when the storage box device is adjusted to a suitable position, by moving the connecting piece 323 on the supporting portion 321, the protrusion 322 on the connecting piece 323 can be embedded in the corresponding tooth groove on the rack mechanism 31, so that the locking mechanism 32 is locked on the rack mechanism 31, and the first box body 1 and the second box body 2 do not move relative to each other, thereby fixing the size of the storage box device, with a simple structure and convenient and quick adjustment.

[0031] like Figure 1 and Figure 2As shown, in this embodiment, the connecting member 323 has a pull rod portion 3231 and a cross rod portion 3232, the pull rod portion 3231 and the cross rod portion 3232 are of integrated structure, the support portion 321 is two correspondingly arranged arc-shaped plates, the cross rod portion 3232 spans between the two arc-shaped plates, the pull rod portion 3231 is an elastic member, and the cross rod portion 3232 can move along the arc-shaped edge of the arc-shaped plate under the action of the pull rod portion 3231, so that the protrusion 322 on the connecting member 323 gradually moves away from the rack mechanism 31 during the movement of the connecting member 323, and the locking mechanism 32 also has a pressing plate 324, and the pressing plate 324 is located on the pull rod portion 32 31, to prevent the connecting piece 323 from falling off when moving on the supporting portion 321, there is a gap between the pull rod portion 3232 and the pressure plate 324, to facilitate the movement of the pull rod portion 3231 under the pressure plate 324, the top of the arc plate has a slot 4 for fixing the position of the cross bar portion 3232, when the cross bar portion 3232 of the connecting piece 323 moves to the highest position of the supporting portion 321, it can be fixed in the slot 4, the vertical distance from the bottom end of the supporting portion 321 to the bottom end of the slot 4 is greater than the protruding height of the protruding portion 322, to ensure that when the cross bar portion 3232 is located in the slot 4, the protruding portion 322 can be completely away from the rack mechanism 31.

[0032] In another embodiment, the support portion 321 is two correspondingly arranged trapezoidal plates.

[0033] For example Figure 1 and Figure 3 As shown, in this embodiment, the inner diameter of the first box body 1 is not less than the outer diameter of the second box body 2, and the first box body 1 and the second box body 2 are both composed of a rectangular bottom plate 100 and four side plates 200 on the sides of the bottom plate 100, and the four side plates 200 can be folded along the sides of the bottom plate 100. Therefore, the first box body 1 and the second box body 2 can be unfolded flat and can be folded to reduce the volume and reduce the occupied area.

[0034] The four side panels 200 are provided with fastener devices 5 between each other. After the side panels 200 are folded along the side of the bottom panel 100 and perpendicular to the bottom panel 200, they are fixed by the fastener devices 5. Figure 4As shown, the fastener device 5 includes a plug-in 51 and an elastic fastening member 52 capable of fixing the position of the plug-in 51, the plug-in 51 is located at the end of the side panel, the fastening member 52 is located on the adjacent side panel, the plug-in 51 corresponds to the fastening member 52, the fastening member 52 is located in a rectangular frame 210 of the side panel, the plug-in 51 can extend into the rectangular frame 210, and the fastening member 52 can, under the action of elasticity, vertically press against the plug-in 51 and press tightly, so that the side panel where the plug-in 51 is located and the side panel where the fastening member 52 is located can be fastened to each other.

[0035] Another example Figure 1 As shown, in the present embodiment, at least one of the side panels 200 is provided with a ventilation channel 220 and a ventilation channel adjustment plate (not shown in the figure), the ventilation channel adjustment plate is a thin plate commonly used in the prior art, the ventilation channel adjustment plate has a through hole complementary to the ventilation channel 220, the ventilation channel adjustment plate is installed on one side of the side panel 200 by a slide groove (not shown in the figure) used by conventional technical means, and can be moved on the side panel 200, because the through hole on the ventilation channel adjustment plate is complementary to the ventilation channel 220, the ventilation channel adjustment plate can gradually change the cross-sectional area of ​​the ventilation channel 220 during the gradual movement process, and the cross-sectional area of ​​the ventilation channel 220 in the storage box device is adjusted according to actual needs to maintain air circulation in the storage box device.

[0036] Another example Figure 5 As shown, in the present embodiment, a hollow frame structure 6 is connected between the first box body 1 and the second box body 2, and an adjustment device 3 is provided between the frame structure 6 and the first box body 1 and between the frame structure 6 and the second box body 2, so that the length or height of the storage box device can be adjusted. It has a wide range of applications, is easy to use, does not occupy space, and is convenient for transportation.

[0037] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
