[0040] like Figures 2 to 6 As shown, the main improvements of the box lock include a lock pin Ⅰ8, a rear shell Ⅰ11 and a lock nose 12. The lock pin Ⅰ8 is in the shape of a long strip and can be installed in the installation cavity Ⅰ11a of the rear shell Ⅰ11 so as to be linearly movable in the left and right directions. A plug hole Ⅰ11b is provided at each of the two ends of the top of the rear shell Ⅰ11. Two lock noses 12 are plug-fitted with the plug holes Ⅰ11b. A lock hole 12a is provided at the lower part of the lock nose 12. Openings 8d matching the lock nose 12 are provided at both ends of the lock pin Ⅰ8, and a lock column Ⅰ8c matching the lock hole 12a is provided next to the opening 8d.

[0041] A lock pin I position locking mechanism is arranged in the rear shell I11; the lock pin I position locking mechanism includes a baffle 10 and an elastic element, the baffle 10 is composed of a bottom plate 10a, a top plate 10b and a vertical plate 10c between the bottom plate 10a and the top plate 10b, an elastic element is arranged between the bottom plate 10a and the rear shell I11, and when the baffle 10 is only acted upon by the elastic element, the top plate 10b is in a position at the opening 8d to block the movement of the lock column I8c; the elastic element is a spring 9.

[0042] The locking pin Ⅰ8 is provided with a plurality of transverse oblong holes 8b, and the locking pin Ⅰ8 is installed in the installation cavity Ⅰ11a of the rear shell Ⅰ11 through the oblong holes 8b so as to be linearly movable in the left-right direction.

[0043] The lock pin I8 is linearly moved in the left and right directions through the lock core connecting member 5, and the lock core connecting member 5 and the lock pin I8 are respectively provided with meshing teeth I5a and meshing teeth II8a that mesh with each other.

[0044] The lock core connecting member 5 is fixedly connected to the lock core 3 ; the lock core 3 is installed in the lock body 4 .

[0045] The working principle of the box lock is:

[0046] like Figure 7 and Figure 8 As shown, during the locking operation, the box cover and the box body are closed, and the lock nose 12 is inserted into the hole of the rear shell Ⅰ11 to compress the baffle 10. The baffle 10 no longer blocks the movement trajectory of the lock pin Ⅰ8. At this time, the lock core 3 is rotated with the key to drive the lock core connector 5 to rotate 90° counterclockwise. The lock core connector 5 is engaged with the lock pin Ⅰ8 gear to drive the lock pin Ⅰ8 to move laterally, and cooperate with the lock nose 12 to complete the locking action; during the unlocking operation, the lock core 3 is rotated with the key to drive the lock core connector 5 to rotate 90° clockwise. The lock core connector 5 is engaged with the lock pin Ⅰ8 gear to drive the lock pin Ⅰ8 to move laterally, and the lock pin Ⅰ8 is separated from the lock nose 12, and the box cover can be opened. At the same time, the baffle 10 pops up to block the movement trajectory of the lock pin Ⅰ8, so that the locking operation cannot be performed when the box cover and the box body are not closed. Example 2

[0047] This embodiment shows the specific structure and working principle of a box lock with a single lock and a single hook structure.

[0048] The difference from Example 1 is that Fig. 9 As shown, this embodiment is a single hook structure.

[0049] The single-lock single-hook structure box lock includes a lock pin II 14, a rear shell II 15 and a lock nose 12, combined with Fig.10 and Fig.11 The lock pin II 14 can be linearly moved in the left and right directions and installed in the installation cavity II 15a of the rear shell II 15. A plug hole is arranged on the top of the rear shell II 15, and the lock nose 12 is plugged into the plug hole. A lock hole 12a is arranged at the lower part of the lock nose 12, and a lock column II 14b matching the lock hole 12a is arranged on the lock pin II 14; the lock pin II 14 is linearly moved in the left and right directions through the lock core connector 5, and meshing teeth I5a and meshing teeth III14a that mesh with each other are respectively arranged on the lock core connector 5 and the lock pin II 14.

[0050] The working principle of the box lock is:

[0051] like Fig.12 and Fig.13As shown, during the locking operation, the box cover and the box body are closed, and the lock nose 12 is inserted into the hole of the rear shell Ⅱ15 to compress the baffle 10. The baffle 10 no longer blocks the movement trajectory of the lock pin Ⅱ14. At this time, the lock core 3 is rotated with the key to drive the lock core connector 5 to rotate 90° counterclockwise, and the lock core connector 5 is engaged with the lock pin Ⅱ14 gear to drive the lock pin Ⅱ14 to move laterally, and cooperate with the lock nose 12 to complete the locking action; during the unlocking operation, the lock core 3 is rotated with the key to drive the lock core connector 5 to rotate 90° clockwise, and the lock core connector 5 is engaged with the lock pin Ⅱ14 gear to drive the lock pin Ⅱ14 to move laterally, and the lock pin Ⅱ14 is separated from the lock nose 12, and the box cover can be opened. At the same time, the baffle 10 pops up to block the movement trajectory of the lock pin Ⅱ14, so that the locking operation cannot be performed when the box cover and the box body are not closed.
