The cover 1 has an open state and a closed state. When the cover 1 is in the open state, a user can put in or take out an item from inside of the main body 2 through an opening of the main body 2; and when the cover 1 is in the closed state, the cover 1 closes the opening at a top of the main body 2, i.e., the cover 1 closes an opening of the storage box.

The storage box further includes a locking mechanism 3, and the main body 2 includes a front panel 21 and a rear panel 22, where the rear panel 22 is rotatably connected to the cover 1. When the cover 1 is in the closed state, the locking mechanism 3 is capable of locking and unlocking the cover 1 and the front panel 21, i.e., the locking mechanism 3 is provided with an unlocking position and a locking position, and the locking mechanism 3 is capable of sliding or rotating between the unlocking position and the locking position. The locking mechanism 3 is mounted on the cover 1. When the locking mechanism 3 is located at the locking position and the cover 1 is in the closed state, the cover 1 cannot rotate relative to the front panel 21, i.e., the cover 1 cannot be opened; and when the locking mechanism 3 is located at the unlocking position, the cover 1 is capable of rotating relative to the front panel 21 or the main body 2, i.e., the cover 1 is capable of moving between the open state and the closed state.

The cover 1 includes a first mounting part 11, and the first mounting part 11 is configured for supporting and fixing the locking mechanism 3. The locking mechanism 3 is capable of sliding or rotating at a position of the first mounting part 11, such that the locking mechanism 3 moves between the unlocking position and the locking position.

Specifically, the first mounting part 11 includes a first groove wall 112, a second groove wall 113 and a mounting groove 111, where the mounting groove 111 is located between the first groove wall 112 and the second groove wall 113, the first groove wall 112 is located above the mounting groove 111, i.e., the first groove wall 112 is located at a top of the first mounting part 11; and the second groove wall 113 is located below the mounting groove 111, i.e., the second groove wall 113 is located at a bottom of the first mounting part 11. The locking mechanism 3 includes an operation panel 33 and a first connecting part 31. The user can slide or rotate the entire locking mechanism 3 through the operation panel 33. The first connecting part 31 protrudes from the operation panel 33 of the locking mechanism 3, the first connecting part 31 extends or protrudes in a direction from the operation panel 33 to the rear panel 22, the first connecting part 31 is partially or completely located in the mounting groove 111, and the first connecting part 31 is capable of sliding in the mounting groove 111. The operation panel 33 is located at an opening of the mounting groove 111 or outside the opening, and the operation panel 33 partially covers the opening of the mounting groove 111.

A top of the first connecting part 31 is arranged opposite to the first groove wall 112. A sliding groove 311 is further formed at the top of the first connecting part 31, and a sliding rail 1121 is arranged on the first groove wall 112, where the sliding groove 311 is in fit with the sliding rail 1121. After the locking mechanism 3 is mounted, the sliding rail 1121 is partially or completely accommodated in the sliding groove 311. An opening of the sliding groove 311 faces the first groove wall 112, and the sliding rail 1121 extends in a direction from the first groove wall 112 to the second groove wall 113. A length direction of the sliding rail 1121 is parallel to a surface where a bottom wall of the mounting groove 111 is located, i.e., the length direction of the sliding rail 1121 is parallel to a surface where the front panel 21 is located, and the length direction of the sliding rail 1121 is a direction in which the locking mechanism 3 slides between the unlocking position and the locking position.

A bottom of the first connecting part 31 is arranged opposite to the second groove wall 113. Support protrusions 312 are arranged at the bottom of the first connecting part 31, and the support protrusions 312 extend in a direction from the bottom of the first connecting part 31 to the second groove wall 113. When the locking mechanism 3 is mounted on the cover 1, the support protrusions 312 abut against an inner side of the second groove wall 113, and when the locking mechanism 3 slides horizontally, the support protrusions 312 rub against the second groove wall 113 in a sliding manner. The support protrusions 312 are made of a wear-resistant material, the number of the support protrusions 312 is three, and the three support protrusions 312 are respectively located at a left end, a middle and a right end of the second groove wall 113, to maintain stability of the locking mechanism 3 sliding on the second groove wall 113.

The locking mechanism 3 further includes a second connecting part 32, the second connecting part 32 protrudes from the operation panel 33 of the locking mechanism 3, and the second connecting part 32 extends or protrudes in a direction from the operation panel 33 to the rear panel 22. The locking mechanism 3 is integrated through injection molding, i.e., the operation panel 33, the second connecting part 32 and the first connecting part 31 are integrally formed through injection molding. The first connecting part 31 is located above the second connecting part 32, and the second connecting part 32 is arranged opposite to a surface where the support protrusions 312 on the first connecting part 31 are located.

The second connecting part 32 further includes a protruding portion 321, and the protruding portion 321 protrudes upward, i.e., the protruding portion 321 extends in a direction towards the first connecting part 31. The front panel 21 includes a second mounting part 211, the second mounting part 211 and the front panel 21 are integrated through injection molding, and the second mounting part 211 is located in a front of the front panel 21. When the locking mechanism 3 is at the locking position, the second mounting part 211 and the second connecting part 32 are arranged opposite to each other, and the second connecting part 32 is located below the second mounting part 211, i.e., the second mounting part 211 is located between the first connecting part 31 and the second connecting part 32.

The second mounting part 211 is further provided with a fixing hole 2111, the fixing hole 2111 is in fit with the protruding portion 321. When the locking mechanism 3 is at the locking position, the protruding portion 321 is at least partially located in the fixing hole 2111, such that the locking mechanism 3 is engaged with the second mounting part 211, thereby improving the stability of the locking mechanism 3 at the locking position and reducing the likelihood of opening the locking mechanism 3 in an unintended state.

The cover 1 further includes a first fixing part 12, and the first fixing part 12 is fixedly connected to or integrated with the cover 1 through injection molding. The front panel 21 further includes a second fixing part 212, and the second fixing part 212 is fixedly connected to or integrated with the front panel 21 through injection molding. The first fixing part 12 and the second fixing part 212 are arranged opposite to each other, the first fixing part 12 is located above the second fixing part 212, and both the first fixing part 12 and the second fixing part 212 are provided with through holes. The through holes on the two fixing parts are communicated with and arranged opposite to each other, and locks such as coded locks can be arranged at the through holes to improve the security of the storage box.

When the cover 1 is in the closed state and the locking mechanism 3 is at the locking position, the protruding portion 321 of the locking mechanism 3 is located in the fixing hole 2111, which improves the stability of the locking mechanism 3 at the locking position. Under the action of the first connecting part 31 and the first mounting part 11, the locking mechanism 3 moves with rotation of the cover 1. The second mounting part 211 is located between the second groove wall 113 and the second connecting part 32. In this case, when the cover 1 rotates to the open state, the second connecting part 32 abuts against the second mounting part 211 to prevent the rotation of the cover 1, so as to achieve the locking of the cover 1. When the locking mechanism 3 is at the unlocking position, the second mounting part 211 between the second groove wall 113 and the second connecting part 32 is removed, such that there is no structure capable of preventing the rotation of the cover 1 between the second groove wall 113 and the second connecting part 32, thereby achieving the unlocking of the locking mechanism 3.
