Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, fig. 2 and fig. 3 together, a locking device according to an embodiment of the present application will now be described.

According to the locking device of the embodiment of the application, the locking device comprises a shell 1, and a pull ring structure 2, a moving structure 3 and a locking structure 4 which are arranged on the shell 1, wherein the moving structure 3 comprises a slider 30 capable of moving back and forth, the locking structure 4 comprises a lock catch 40 capable of rotating, the slider 30 can be linked with the lock catch 40 to rotate and retract into the shell 1 in the process of moving back and forth, and meanwhile, the slider 30 can be linked with the lock catch 40 to rotate and extend out of the shell 1 in the process of moving back and forth; the pull ring structure 2 is rotatably arranged and can move in a linkage manner with the slider 30 in the rotating process, and the pull ring structure 2 can be kept fixed at the first end and the second end of the rotating stroke of the pull ring structure, so that the lock catch 40 can keep the extending state of extending out of the shell 1 and the retracting state of retracting into the shell 1.

According to the locking device provided by the embodiment of the application, the whole locking device can be quickly unlocked and quickly locked in a mode that the pull ring structure 2 is rotated to link the sliding block 30 to move. Specifically, the sliding block 30 is linked with the lock catch 40 to rotate and retract into the shell 1, so that the whole locking device can be unlocked quickly; the sliding block 30 is linked with the lock catch 40 to rotate and extend out of the shell 1, so that the whole locking device can be quickly locked; and because the pull ring structure 2 can be kept fixed at the first end and the second end of the rotation stroke of the pull ring structure, and the lock catch 40 can be kept in a stable extending state and a stable retracting state, when the pull ring structure is actually operated by a user, the user only needs to control the pull ring structure 2 to rotate to the two ends of the rotation stroke of the pull ring structure, so that the quick unlocking and the quick locking of the locking device can be realized, the whole operation process is simple and convenient, and the purpose of quickly plugging and unplugging the locking device can be achieved without the unlocking gesture of the user.

In some embodiments of the present application, referring to fig. 2, fig. 3 and fig. 5 to fig. 8, a card corner 301 is disposed at an end of the slider 30 away from the lock catch 40, and a corner 200 is disposed at an end of the tab structure 2 corresponding to the card corner 301, wherein the corner 200 is used for rubbing and propping against the card corner 301 during rotation.

The corner portion 200 according to the embodiment of the present application can rub against the snap corner portion 301, thereby providing a tactile feedback throughout the rotation of the tab structure 2. Obviously, when the user rotates the pull ring structure 2, especially when the whole locking device is unlocked quickly, such a hand feeling feedback can give the user an obvious unlocking prompt, specifically, at the instant when the corner portion 200 abuts against the end portion of the clamping corner portion 301 (when the pull ring structure 2 reaches the second end of the rotation stroke thereof), the frictional hand feeling feedback can disappear instantly, so as to fully prompt the user that the user does not need to further rotate the pull ring structure 2, thereby fully avoiding the occurrence of a phenomenon of damaging the locking device.

It is understood that corner portion 200 can exert a certain supporting and rubbing action on adjacent first side wall 3010 and second side wall 3020 of corner portion 301, and even on the side walls on both sides of first side wall 3010, when rubbing against corner portion 301. Further, the corner segment 200 slides along the first side wall 3010 to bear against the second side wall 3020 as the tab structure 2 is rotated from its first end of rotational travel to its second end.

In some embodiments of the present application, referring to fig. 2, fig. 3, fig. 5 and fig. 6, the corner portion 200 is configured as a U-shape or a V-shape adapted to the corner portion 301 to sufficiently satisfy the requirements of friction and propping.

In some embodiments of the present application, please refer to fig. 1 and fig. 3 together, when the control tab structure 2 rotates from the first end to the second end of the rotation stroke, the control tab structure can rotate to push the sliding block 30 to move toward the lock catch 40, so as to drive the lock catch 40 to rotate and retract into the housing 1, so as to realize the quick unlocking of the whole locking device (as shown in fig. 3); referring to fig. 1 and 2, when the control tab structure 2 rotates from the second end to the first end of the rotation stroke, the slider 30 is reset to move under the reset action, and simultaneously the lock catch 40 is reset to rotate to the initial position under the reset action, the lock catch 40 at the initial position extends out of the housing 1 and can be matched with the lock hole position of the device, so as to realize the quick locking of the whole locking device (as shown in fig. 2).

The pull ring structure 2 according to the embodiment of the application is matched with the reset action of the reset slide block 30 to realize linkage control on the slide block 30; similarly, the slide block 40 cooperates with the reset function of the reset lock 40 to realize the linkage control of the lock 40.

In some embodiments of the present application, referring to fig. 2, when the tab structure 2 rotates to the first end of its rotation stroke, one end of the tab structure 2 is engaged with the housing 1, so that the lock catch 40 stably protrudes from the housing 1; referring to fig. 3, when the pull ring structure 2 rotates to the second end of the rotation stroke, the other end of the pull ring structure 2 is supported against the slider 30 and remains fixed, so that the lock catch 40 is stably retracted into the housing 1.

According to the tab structure 2 of the embodiment of the application, the rotation stroke of the tab structure 2 is adapted to the movement stroke of the slider 30, so that when the tab structure 2 is supported by the slider 30 at the second end of the rotation stroke, the reset action of the slider 30 can be balanced with the supporting action provided by the tab structure 2, and the tab structure 2 and the slider 30 can be kept in a relatively fixed state.

It will be appreciated that the return action experienced by the lock catch 40 and the return action experienced by the slider 30 both facilitate or assist in the pivoting of the tab structure 2 as the tab structure 2 pivots from the second end of its pivotal travel to the first end (i.e., the state shown in figure 3 transitions to the state shown in figure 2).

The sliding chute 300 according to the embodiment of the present application is parallel to the moving direction of the slider 30, so that the first restoring member 31 can elastically expand and contract in the direction parallel to the sliding chute 300. Specifically, when the tab structure 2 rotates and pushes the slider 30 to approach the latch 40, the first restoring member 31 is compressed by a force to have elastic potential energy for restoration; when the pull ring structure 2 rotates, the first restoring member 31 releases the elastic potential energy to extend and push the sliding block 30 to restore.

It will be understood that the amount of expansion and contraction of the first restoring member 31 is adapted to the displacement stroke of the slider 30. Specifically, referring to fig. 1, when the first restoring member 31 is fully compressed into the sliding slot 300, the end of the sliding block 30 abuts against the internal structure of the housing 1, and at this time, the sliding block 30 cannot move further, and the first restoring member 31 cannot be further compressed.

In some embodiments of the present application, referring to fig. 1 and fig. 5, the first restoring member 31 employs a helical cylindrical spring to perform a specific restoring function.

The second reset part 41 according to the embodiment of the present application can be elastically deformed when the latch 40 is rotated to be retracted into the housing 1, and then has elastic potential energy for resetting the latch 40.

In some embodiments of the present application, please refer to fig. 1 and fig. 5, the second reset element 41 includes a reset spring 410, and the reset spring 410 is attached to one end of the lock catch 40 close to the slider 30.

According to the second reset piece 41 of the embodiment of the present application, the reset spring 410 is attached to the latch 40 to perform the reset function. Specifically, referring to fig. 1, when the slider 30 moves and rotates against the end of the latch 40, the reset spring 410 deforms along with the rotation direction of the latch 40, and when the slider 30 resets away from the latch 40, the reset spring 410 resets the latch 40 under the action of elastic force, so that the latch 40 rotates to the initial position.

In some embodiments of the present application, referring to fig. 1, 5 and 9, a wedge-shaped chuck 400 is disposed at an end of the lock 40 away from the slider 30.
