Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] Example 1

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a space-adjustable packaging box, including an outer box 2, an inner box 1 inside the outer box 2, four locking components 3 on the outer surface of the inner box 1, and a cover component 4 on the top of the inner box 1. The locking components 3 include a fixing plate 307 fixedly connected to the outer surface of the inner box 1, a movable plate 304 slidably connected to the outer surface of the fixing plate 307, and two locking blocks 305 hinged to the bottom end of the fixing plate 307. A limit block 308 is provided inside the locking block 305.

[0033] Specifically, a rectangular groove is formed on the outer surface of the fixed plate 307. A fixed rod 301 is fixedly connected inside the rectangular groove on the outer surface of the fixed plate 307. A connecting block 303 is slidably connected to the outer surface of the fixed plate 307. The outer surface of the connecting block 303 is fixedly connected to the upper surface of the movable plate 304. A spring 302 is fixedly connected between the upper surface of the connecting block 303 and the top of the inner wall of the rectangular groove. Four limiting protrusions are provided on the side of the movable plate 304 near the fixed plate 307. A limiting groove that mates with the limiting protrusions is provided on the outer surface of the fixed plate 307. A locking block 305 is provided on the side of the movable plate 304 near the movable plate 304. A cross-shaped limiting groove is provided to cooperate with the limiting protrusion. A rectangular notch is provided on the outer surface of the outer box 2 to cooperate with the fixing plate 307 and the locking block 305. An opening is provided inside the locking block 305. An arc groove is provided on the outer surface of the outer box 2 to communicate with the rectangular notch. A limiting block 308 that cooperates with the arc groove is fixedly connected to the inner wall of the opening inside the locking block 305. Notches for the installation block 403 to move are provided on the outer surface of the outer box 2 and the outer surface of the inner box 1. Limiting plates 306 are fixedly connected to both sides of the fixing plate 307. The gap between the limiting plate 306 and the outer surface of the inner box 1 is the same as the thickness of the outer box 2.

[0034] Further, the inner box 1 is pulled up, causing the locking block 305 to move to the position of the arc-shaped groove on the outer surface of the outer box 2. Then, the movable plate 304 is pulled up, causing the two limiting protrusions on the inner side of the outer surface of the movable plate 304 to separate from the cross-shaped limiting groove on the outer surface of the locking block 305. Then, the locking block 305 is rotated, thereby causing the opening inside the locking block 305 to insert into the outer surface of the outer box 2. During insertion, the inner box 1 and the outer box 2 are locked by the movement of the limiting block 308 inside the arc-shaped groove on the outer surface of the outer box 2. Then, the movable plate 304 is lowered. Under the action of the spring 302, the two limiting protrusions on the inner side of the outer surface of the movable plate 304 are pulled up to the position of the arc-shaped groove on the outer surface of the outer box 2. The two outer limiting protrusions engage with the cross-shaped limiting groove on the outer surface of the locking block 305, thereby locking the locking block 305 and ultimately locking the inner box 1 and the outer box 2. When the locking block 305 rotates, when the locking block 305 retracts, it causes the cross-shaped limiting groove on the outer surface of the two locking blocks 305 to engage with the two limiting protrusions on the inner side of the outer surface of the movable plate 304. When the locking block 305 expands outward, it rotates to a position that abuts against the bottom end of the limiting plate 306, so that the cross-shaped limiting groove on the outer surface of the locking block 305 can engage with the limiting protrusion on the outer side of the outer surface of the movable block.

[0035] Example 2

[0036] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The sealing assembly 4 includes a cover plate 401 disposed on the top of the inner box 1. Four insert rods 402 are fixedly connected inside the cover plate 401. Mounting blocks 403 are disposed on the outer surface of the insert rods 402. Two rotating blocks 404 are hinged to the bottom end of the mounting blocks 403. Inserting blocks 406 are disposed inside the mounting blocks 403.

[0037] Specifically, the lower surface of the rotating block 404 has an insertion hole that mates with the insertion block 406, the bottom of the mounting block 403 has a rectangular groove, the inside of which a fixing block 405 is fixedly connected, the insertion block 406 is fixedly connected to the upper surface of the fixing block 405, the lower surface of the rotating block 404 has an insertion hole that mates with the insertion block 406, the upper surface of the mounting block 403 has a circular hole that mates with the insertion rod 402, the inner wall of the circular hole has several soft extrusion rings, and the outer surface of the insertion rod 402 has a groove that mates with the soft extrusion rings.

[0038] Furthermore, by pulling up the insert rod 402, the insert rod 402 is lifted inside the mounting block 403. The soft compression ring inside the mounting block 403 engages with the groove on the outer surface of the insert rod 402, thereby compressing and limiting the insert rod 402. Then, the rotating block 404 at the bottom of the mounting block 403 is rotated, thereby driving the rotating block 404 to a horizontal position. When the rotating block 404 rotates, the insert block 406 engages with the rotating block 404, thereby locking the rotating block 404. The eight rotating blocks 404 at the bottom work together to support the bottom of the outer box 2. The locking force between the insert block 406 and the rotating block 404 is sufficient to withstand the pressure of the outer box 2. The engagement of the soft compression ring and the groove ensures that the cover plate 401 can lift the inner box 1 and the outer box 2 without falling off.

[0039] Working principle: When using the packaging box, depending on the needs of the items to be placed, choose whether to pull out the inner box 1 to form a double-layer packaging box. When double-layer storage is required, pull up the inner box 1, causing the locking block 305 to move to the position of the arc-shaped groove on the outer surface of the outer box 2. Then, pull up the movable plate 304, causing the two limiting protrusions on the inner side of the outer surface of the movable plate 304 to separate from the cross-shaped limiting groove on the outer surface of the locking block 305. Then, rotate the locking block 305, thereby causing the opening inside the locking block 305 to insert into the outer surface of the outer box 2. During insertion, the movement of the limiting block 308 inside the arc-shaped groove on the outer surface of the outer box 2 locks the inner box 1 and the outer box 2. Then, lower the movable plate 304. Under the action of the spring 302, the two limiting protrusions on the outer side of the outer surface of the movable plate 304 cooperate with the cross-shaped limiting groove on the outer surface of the locking block 305, thereby locking the locking block. 305. Finally, the inner box 1 and outer box 2 are locked together, forming a double-layer packaging box composed of the inner box 1 and outer box 2, realizing the adjustment of the storage space. After the inner box 1 and outer box 2 are adjusted, the cover plate 401 is adjusted. By pulling up the insert rod 402, the insert rod 402 is driven to rise inside the mounting block 403. The soft compression ring inside the mounting block 403 cooperates with the groove on the outer surface of the insert rod 402 to squeeze and limit the insert rod 402. Then, the rotating block 404 at the bottom of the mounting block 403 is rotated, thereby driving the rotating block 404 to a horizontal position. When the rotating block 404 rotates, the insert block 406 cooperates with the rotating block 404 to lock the rotating block 404. The eight rotating blocks 404 at the bottom work together to support the bottom of the outer box 2, thus completing the space adjustment and use of the packaging box.
