[0007] As an improvement, a knob is rotatably mounted on the lock handle, and the knob is provided with a connecting rod, and the connecting rod is linked to the driving assembly, and the knob is rotated to make the driving assembly slide back and forth on the lock handle. In this technical solution, a knob linked to the driving assembly is provided to facilitate the user to apply force, and the user can make the driving assembly slide by turning the knob. The rotary drive design is more conducive to saving installation space, and the knob is linked to the driving assembly through the connecting rod, so the connection stability is better and the linkage reliability is higher.

[0008] As an improvement, a rack structure is provided in the driving assembly, a gear structure meshing with the rack structure is installed on the connecting rod, and the knob is rotated to make the driving assembly slide through the gear structure and the rack structure. In this technical solution, by providing a gear-rack meshing transmission structure between the driving assembly and the knob, the rotary motion is converted into linear motion, the transmission is more reliable and the transmission efficiency is higher, the meshing of the gear structure and the rack structure provides precise control, so that the extension and retraction of the lock tongue can be precisely adjusted to adapt to boxes with different gaps, and the gear structure and the rack structure are integrated in the driving assembly and the connecting rod, so that the structure of the entire locking device is more compact and space-saving.

[0009] As an improvement, the lock handle is provided with a first mounting portion for movably mounting the knob, the knob is provided with a first protrusion, the first mounting portion is provided with a first groove adapted to the first protrusion, the first protrusion is connected to the first groove so that the knob can be rotated and locked, and the first protrusion is disengaged from the first groove so that the knob can be rotated and unlocked. In the present technical scheme, the lock handle is used to install the knob through the first mounting part, and the installation of the knob is simple and reliable. By arranging the first protrusion on the knob and the first groove on the first mounting part, a lockable rotational connection is achieved between the knob and the lock handle. The first protrusion is connected with the first groove to lock the knob rotation, and the knob cannot rotate to control the sliding of the drive component. The first protrusion is disengaged from the first groove to unlock the knob rotation. The knob can be rotated under force to control the sliding of the drive component, preventing the knob from automatically rotating due to external force, which affects the normal use of the lock. The knob is movably connected to the first mounting part, and the user can make the knob move by applying force to the knob, thereby disengaging the first protrusion from the first groove to complete the unlocking. The structural design is ingenious and reliable. On the other hand, in the present scheme, the setting positions of the first protrusion and the first groove are interchangeable. The first protrusion can be set on the first mounting part and the first groove can be set on the knob. The principle is the same.

The knob slides upward to connect the first protrusion with the first groove, thereby realizing rotation locking of the knob. A first reset elastic member is arranged at the bottom of the connecting rod, and elastic force is utilized to realize automatic upward sliding reset of the knob, thereby ensuring that the knob can automatically return to the initial position after operation. The user only needs to press the knob to rotate and unlock the knob, which is more labor-saving to use. When the lock tongue needs to be retracted, the user first presses the knob to make the first protrusion slide downward and disengage from the first groove. At this time, the first reset elastic member is in a compressed force state. The user maintains the pressing force and rotates the knob, thereby enabling the driving assembly to slide and drive the lock tongue to retract. When the lock tongue is retracted and adjusted, the user releases the knob, and the knob slides upward under the action of the first reset elastic member, so that the first protrusion is connected to the first groove. The knob rotation limit is located on the lock handle, thereby avoiding accidental operation, and the operation is simple and labor-saving.

[0011] As an improvement, a second protrusion is provided on the connecting rod, and a second groove adapted to the second protrusion is provided in the gear structure. The second protrusion cooperates with the second groove to make the connecting rod and the gear structure rotate synchronously.

In this technical solution, the second protrusion cooperates with the second groove to prevent the connecting rod and the gear structure from rotating relative to each other. When the knob is rotated under force, the connecting rod can make the gear structure rotate synchronously through the concave-convex matching structure, thereby driving the rack structure to slide, and the rotation is more reliable and efficient. The second protrusion cooperates with the second groove to make the knob slide up and down more reliable, and can prevent the knob from rotating during the sliding process and affecting the use, and the reliability is higher. The first reset elastic member adopts a tower spring to provide the reset force required by the knob, ensuring that the knob can return to the initial position after operation, and the tower spring will not be displaced by the rotation of the knob, and the structure is more reliable.

The arc surface structure is connected between each adjacent side surface, and the arc surface structure has a certain rotation guiding effect on the rolling piece, which can make the rolling piece rotate to the side surface and fit the inner wall of the slot, so that the rolling piece has a higher rotation efficiency and a higher locking efficiency.

[0014] As an improvement, the slot is provided with a plurality of first guide slopes adapted to the rolling element, and the first guide slopes guide the rolling element to rotate so as to fit with the side of the rolling element.

The rolling member 31 is provided with a plurality of side surfaces 311 of a planar structure, and each adjacent side surface 311 is connected by an arc surface structure 312. The rolling member 31 is installed at the end of the lock tongue 3 for cooperating with the card slot 11 of the lock seat 1, and the rolling member 31 allows the lock tongue 3 to be connected to or separated from the card slot 11. The rolling element 31 can be flexibly connected and disconnected. The side surface 311 of the planar structure can better fit the inner wall of the slot 11, so that the rolling element 31 is connected to the slot 11 in a surface-to-surface manner rather than a surface-to-line manner, and the locking efficiency is higher. The adjacent side surfaces 311 are connected by the arc surface structure 312, and the arc surface structure 312 has a certain rotation guiding effect on the rolling element 31, so that the rolling element 31 can be rotated until the side surface 311 fits the inner wall of the slot 11, thereby making the rolling element 31 more efficient in rotation and locking.

[0046] More specifically, Figures 4 to 8 As shown, the card slot 11 is provided with a plurality of first guiding bevels 111 adapted to the rolling member 31. The first guiding bevels 111 guide the rolling member 31 for rotation so as to fit with the side surface 311 of the rolling member 31. By setting the first guiding bevels 111 to guide the rolling member 31 for rotation, it is ensured that the rolling member 31 can move along a predetermined path when connected to or disconnected from the card slot 11, making the positioning of the rolling member 31 easier, and the user can easily lock and unlock the lock.
