Referring to fig. 2, 3 and 4, in the present embodiment, when the locking device 30 is forced to move into the locking device receiving hole 111, the locking hook 301 contacts with the hook surface of the latch hook 231.

In this embodiment, fig. 4 is a schematic view illustrating the change of the engagement state between the latch tongue 23 and the lock catch 30, wherein (a) shows a schematic view before engagement, taking the angle of fig. 4 as an example, since the inner and outer hook surfaces of the lock hook 301 and the latch tongue hook 231 have smooth arcs, the force applied to the latch tongue hook 231 from the lock catch 30 is decomposed into a left force and a downward force, the downward force is counteracted by the latch tongue fixing rib 113, the left force pushes the latch tongue 23 to move left, the latch tongue 23 compresses the latch tongue spring 234 and moves to the bottom of the main housing 11, when the latch tongue hook 231 and the lock hook 301 completely avoid, the lock catch 30 loses the barrier and is inserted into the lock catch receiving hole 111 smoothly, and the latch tongue 23 is pushed back to the home position by the elastic force of the latch tongue spring 234, the latch hook 231 is also engaged and fastened with the latch hook 301, and the engaged state shown in fig. 4 (B) is achieved.

Further, in the engaged state, still taking the angle of fig. 4 as an example, the lock catch 30 is located in the lock catch receiving hole 111, when the lock catch 30 is forced to move outward, the hook surfaces of the lock hook 301 and the lock tongue hook 231 are in contact first, since the inner and outer hook surfaces of the lock hook 301 and the lock tongue hook 231 have smooth curvatures, the force applied to the lock tongue hook 231 from the lock catch 30 is decomposed into a leftward force and an upward force, wherein the upward force is still offset by the lock tongue fixing rib 113, the leftward force will cause the lock tongue 23 to move leftward, the lock tongue 23 will compress the lock tongue spring 234 and move toward the bottom of the main housing 11, when the lock tongue hook 231 and the lock hook 301 are completely avoided, the lock tongue 30 will smoothly block the lock catch from being disengaged from the lock catch receiving hole 111, and the lock tongue 23 is pushed back to the original position by the elastic force of the lock tongue spring 234, return to the pre-engagement state shown in fig. 4 (a).

Referring to fig. 3, 5 and 6, further, the rotation center of the C-shaped stopping sidewall 221 is concentric with the rotation centers of the stopping shaft 22 and the motor shaft 211, and the cross section of the C-shaped stopping sidewall 221 surrounds the locking tongue 23 to rotate. When the motor 21 rotates clockwise, power is transmitted to the lock 22 through the motor shaft 211, so that the C-shaped stopping side wall 221 is driven to rotate clockwise, when the C-shaped stopping side wall 221 rotates into the space below the lock tongue leg 233, the space below the lock tongue leg 233 is filled, so that the lock tongue 23 is blocked, the lock tongue 23 is stopped, at this time, if the lock tongue 23 and the lock buckle 30 are in a meshed state, because the lock buckle 30 is only slightly smaller than the lock buckle accommodating hole 111, the lock buckle 30 can not move in other directions, the lock buckle 30 is locked and cannot be pulled out, and the locking effect is achieved.

Further, since the outer diameter of the C-shaped stop sidewall 221 has a curvature and the stop support rib 114 just fits the outer diameter of the C-shaped stop sidewall 221, so as to support the C-shaped stop sidewall 221, even if the latch 30 is subjected to a great pulling force, the C-shaped stop sidewall will not be damaged in the locked state.

In a locked state, the motor 21 rotates counterclockwise, the C-shaped stopping side wall 221 rotates out from below the locking tongue leg 233, no barrier is left below the locking tongue leg 233 to obtain a space again, the locking tongue 23 is released, and when the lock catch 30 is forced to move out of the lock catch accommodating hole 111, the locking tongue 23 can be pushed to move, the locking tongue hook 231 is enabled to avoid the locking tongue hook 301, and then the lock catch 30 moves out of the lock catch accommodating hole 111 smoothly, so that an unlocking effect is achieved.

In order to facilitate understanding of the practical benefits of the present invention, in the present embodiment, there is also provided a notepad 40 having the detent lock structure 10.

Referring to fig. 1 and 7, the notepad 40 includes a locking structure 10, a core 41 and a receiving frame layer 42. The main shell 11 of the locking structure 10 is disposed at the inner edge of the front panel of the notebook 40, and the length of the main shell 11 does not exceed the width of the notebook 40, so as to facilitate better installation;
