The outer box body is hinged to one side of the outer cover, and the inner cover covers the top opening of the outer box body. The connecting component and the password lock are both arranged on the inner cover. The inner cover and the outer box body are locked and opened through the connecting component, and a password lock is provided to lock the connecting component, thereby providing security for the shared express box.

[0020] Step 2: Loosen the nut and move the sliding plate to a suitable position. The movement of the sliding plate drives the left side of the first rotating bracket to slide on the sliding plate. The second rotating bracket rotates while following the movement of the first rotating bracket. Tighten the nut so that the first rotating bracket is fixed on the sliding plate. The first rotating bracket is fixed and cooperates with the second rotating bracket to fix the sliding plate. The partition is fixedly installed on one end of the sliding plate close to the nut.

[0021] Step 3: Move the special-shaped slide plate of the locking assembly toward the direction close to the second spring, the second spring undergoes elastic deformation, the first cover and the second cover are closed, the special-shaped slide plate is released, the elastically deformed second spring recovers, the special-shaped slide plate is pushed back to the initial position, the special-shaped slide plate enters the slot of the second cover, the first cover and the second cover are locked, the label tie is set in the openings on the upper side of the special-shaped slide plate and the upper side of the first cover, the shared express box is locked, and at the same time, it can quickly identify whether the shared express box has been unpacked;

[0022] Step 4: When you want to unpack the shared express box, cut the label tie, move the special-shaped slide plate of the locking assembly towards the direction close to the second spring, open the first upper cover and the second upper cover, loosen the special-shaped slide plate, and the elastically deformed torsion spring recovers, causing the first side plate and the second side plate to rotate. Loosen the nut, move the sliding plate to the initial position, and the first side plate and the second side plate will rotate. The shared express box will be fully unfolded to take the items.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. The first side panel is driven to rotate by the torsion spring that undergoes elastic deformation, and the rotation of the first side panel initially unfolds the first side panel, and the rotation of the first side panel drives the main rotating plate to rotate, and the rotation of the main rotating plate drives the first triangular plate to rotate, and the rotation of the first triangular plate drives the auxiliary rotating plate to rotate, and the rotation of the auxiliary rotating plate drives the second triangular plate to rotate, so that the first side panel is fully unfolded, which is beneficial for the first side panel and the bottom plate to be in the same plane and reduce the storage space; the recovery of the torsion spring that undergoes elastic deformation drives the second side panel to rotate, and the rotation of the second side panel drives the telescopic plate to rotate, and the end of the telescopic plate away from the second side panel is rotatably connected to the bottom plate via a rotating shaft. The second triangular plate is away from one end of the auxiliary rotating plate, so that the telescopic plate moves in a direction away from the second side plate while rotating, so that the first spring is elastically deformed, and the torsion force generated by the torsion spring is much greater than the force required for the elastic deformation of the first spring, which is conducive to the second side plate and the bottom plate being in the same plane, thereby reducing the storage space; the first upper cover and the second upper cover are closed, and the rotation of the first upper cover drives the locking assembly to rotate, and the locking assembly locks the first upper cover and the second upper cover to prevent the shared express box from automatically unfolding. At the same time, by rotating the unfolding device, the telescopic unfolding device, the main cover device and the auxiliary cover device, the shared express box can be quickly unfolded or merged, which is conducive to saving storage space;

[0024] 2. Move the special-shaped slide plate of the locking assembly toward the direction close to the second spring, the second spring undergoes elastic deformation, the first upper cover and the second upper cover are closed, the special-shaped slide plate is released, the elastically deformed second spring recovers, the special-shaped slide plate is pushed back to the initial position, the special-shaped slide plate enters the slot of the second upper cover, the first upper cover and the second upper cover are locked, and the label tie is set in the openings on the upper side of the special-shaped slide plate and the upper side of the first upper cover, which is conducive to quickly locking the shared express box and can quickly identify whether the shared express box has been unpacked;

[0025] 3. Loosen the nut and move the sliding plate to the appropriate position. The movement of the sliding plate drives the left side of the first rotating bracket to slide on the sliding plate. The second rotating bracket rotates while following the movement of the first rotating bracket. Tighten the nut so that the first rotating bracket is fixed on the sliding plate. The first rotating bracket is fixed and cooperates with the second rotating bracket to fix the sliding plate. The partition is fixedly installed on one end of the sliding plate close to the nut. The partition is fixed, so that the internal space of the shared express box is limited to a suitable size, which is conducive to adjusting the space size according to different items and reducing the filler consumed by fixing items.

[0042] The rotating and unfolding device 2 includes: a first side plate 21, a main rotating plate 22 and a connecting assembly. The first side plate 21 is rotatably connected to the left and right sides of the base plate 1 through a rotating shaft. A torsion spring is arranged on the rotating shaft of the first side plate 21. One end of the torsion spring is fixedly mounted on the base plate 1, and the other end of the torsion spring is fixedly mounted on the first side plate 21. The two main rotating plates 22 are respectively rotatably connected to the front and rear sides of the first side plate 21 through the rotating shaft. The connecting assembly is mounted on one end of the main rotating plate 22 away from the first side plate 21.

[0043] The elastically deformed torsion spring recovers and drives the first side plate 21 to rotate. The rotation of the first side plate 21 initially unfolds the first side plate 21. The rotation of the first side plate 21 drives the main rotating plate 22 to rotate.
