DETAILED DESCRIPTION

[0024] Reference Figure 1-Figure 6 As shown, a new type of lock structure includes a protective lock core type lock body 11, which includes a groove 13 and a through hole 12. The groove 13 is used to accommodate a lock buckle and a lock beam. A cover 1 and a lock core sleeve 6 are arranged in the through hole 12. The cover 1 is hollow with a side cutout 16. The hollow part accommodates a connector 4, which can rotate in the cover 1. A lock core 15 is arranged in the lock core sleeve 6. The lock core sleeve 6 is rotatably connected to the lock core 15. The connector 4 is coaxially connected to the lock core 15. The cross-section of the connector 4 is a fan-shaped structure, and one side of the connector 4 is a plane structure 19. A straight beam hole 26 is arranged on the side of the protective lock core type lock body 11; when the plane structure 19 of the connector 4 corresponds to the side cutout 16, the straight beam 9 passes through the straight beam hole 26, the side cutout 16 and the groove 13 in sequence, and the connector 4 is rotated, and the connector 4 is engaged with the annular groove limiting portion 20 of the straight beam 9.

[0025] The lock buckle, lock beam and part of the straight beam 9 are hidden in the groove 13, which plays a role in protecting shearing and sawing, so that the lock structure has a higher protection level and the safety is greatly improved.

[0026] It also includes a key 10, a protective lock core type lock body 11 includes a mini keyhole 27, and the lock core 15 includes a keyhole. The key 10 cooperates with the lock core 15. When in use, the key 10 rotates to drive the lock core 15 to rotate, thereby driving the connector 4 to rotate.

[0027] One side of the lock core 15 is flush with the lock core sleeve 6, and the other side of the lock core 15 protrudes from the lock core sleeve 6 to form a connecting block 24. Correspondingly, the connecting head 4 is provided with a connecting groove 25, and the connecting block 24 is placed in the connecting groove 25 to ensure that the lock core 15 and the connecting head 4 form a coaxial connection.

[0028] The cover 1 also includes an R-cut 17, which accommodates part of the lock core pin 3. The lock core sleeve 6 is provided with a cutout 18, which accommodates part of the lock core pin 3. At this point, the cover 1 and the lock core sleeve 6 are fixed and no relative displacement occurs.

[0029] The anti-drilling piece 7 is also included. The anti-drilling piece 7 is inside the protective lock core type lock body 11 and is located outside the lock core sleeve 6 to protect the lock core 15.

[0030] It also includes a countersunk screw 2, which is used to fix the blind cover 1 so that it will not rotate in a circle. Specifically, the blind cover 1 is provided with a positioning groove corresponding to the countersunk screw 2, and the head and neck cap of the countersunk screw 2 can resist the positioning groove of the blind cover 1 to prevent the blind cover 1 from loosening. The other end of the countersunk screw 2 is fixedly installed with the protective lock core type lock body 11.

[0031] The protective lock core type lock body 11 is provided with a straight beam pin hole 14, which is used to accommodate the straight beam pin spring 8 and the straight beam pin 5. Correspondingly, the straight beam 9 is provided with a positioning groove 21, the outer side of the positioning groove 21 is a limiting baffle 22, the bottom surface of the positioning groove 21 is a plane structure parallel to the axis of the straight beam 9, the limiting baffle 22 is perpendicular to the bottom surface of the positioning groove 21, and the limiting baffle 22 prevents the straight beam pin 5 from sliding out along the straight beam 9. The inner side of the positioning groove 21 is a gentle slope baffle 23. When the straight beam pin spring 8 contracts, the straight beam pin 5 can slide out of the positioning groove 21 along the gentle slope baffle 23. The purpose of this design is to prevent the straight beam 9 from sliding out of the protective lock core type lock body 11, so as to avoid the problem that the straight beam 9 is easy to lose as a single component.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
