To illustrate the technical solution of the present invention, the following description is made with reference to the specific drawings and examples.

In a first aspect, referring to fig. 1 to 3, an embodiment of the invention provides a locking device 100, where the locking device 100 includes a fixed member 10 and a movable member 20. The fixed member 10 is provided with a groove 11, the movable assembly 20 includes a pushing member 21 and a movable member 22, one end of the movable member 22 is movably inserted into the groove 11, one of the pushing member 21 and the movable member 22 is provided with a first sliding slot 23, the other one of the pushing member 21 and the movable member 22 is provided with a limiting member 24, the limiting member 24 is slidably connected with the first sliding slot 23, and the extending direction of the first sliding slot 23 and the moving direction of the pushing member 21 are obliquely arranged.

When the movable member 22 is inserted into the groove 11, the locking device 100 is in a locked state; the pushing member 21 can be forced to move and drive the movable member 22 to move through the limiting member 24, and the movable member 22 can slide out of the groove 11, so that the locking device 100 is in an open state.

In this embodiment, the pushing member 21 is convexly provided with a limiting member 24, the movable member 22 is provided with a first sliding slot 23, and the limiting member 24 is slidably connected with the first sliding slot 23. The first sliding groove 23 may be a through groove or a blind groove.

It is understood that, in other embodiments, the limiting member 24 is disposed on the movable member 22, and the first sliding groove 23 is disposed on the pushing member 21, which is not limited herein.

The operation of the locking device 100 is as follows: firstly, the fixed member 10 and the movable member 20 are disposed at an interval, and one end of the movable member 22 is inserted into the groove 11, at this time, the locking device 100 is in a locked state; pressing the pushing member 21, the pushing member 21 being forced to move and driving the movable member 22 to move through the limiting member 24, the movable member 22 being able to slide out of the groove 11, so that the locking device 100 is in an open state; when the pushing member 21 is moved in the reverse direction, the limiting member 24 drives the movable member 22 to move toward the direction close to the fixed member 10 until one end of the movable member 22 is inserted into the groove 11 again, and the locking is completed again.

Therefore, the locking device 100 can be slidably connected to the first sliding slot 23 through the limiting member 24, so that the pushing member 21 drives the movable member 22 to move, and one end of the movable member 22 can be inserted into or slid out of the groove 11, so that the locking or unlocking of the locking device 100 is realized, and the opening and closing are easy; and because the connection relation among all the components is simple, old or damaged components can be replaced in time, and the locking device 100 can be installed at any appointed position according to the requirement, the technical problems of complex structure, difficult opening and closing and single installation position of the existing locking device are effectively improved.

In one embodiment of the invention, the direction of movement of the pusher 21 is perpendicular to the direction of movement of the movable member 22. Therefore, the pushing member 21 moves along the first direction to drive the movable member 22 to move along a second direction perpendicular to the first direction, so that the movable member 22 is clamped in the groove 11 or separated from the groove 11, and the locking device 100 is switched between the locking state and the unlocking state. It will be appreciated that in other embodiments, the direction of movement of the pusher 21 and the direction of movement of the movable member 22 may be inclined.

Referring to fig. 3, in the present embodiment, the first direction is a horizontal direction, and the second direction is a vertical direction. The first sliding groove 23 includes a first end 231 and a second end 232, and a distance between the first end 231 and the fixing member 10 is smaller than a distance between the second end 232 and the fixing member 10. When the movable member 22 is clamped in the groove 11, the position-limiting member 24 is located at the second end 232, and the locking device 100 is in the locking state; when the pushing member 21 moves along the first direction and drives the movable member 22 to move along the second direction through the limiting member 24 until the limiting member 24 is located at the first end 231, the movable member 22 is separated from the groove 11, that is, the locking device 100 is in the open state.

Referring to fig. 1 to fig. 3, in an embodiment of the present invention, the locking device 100 further includes a lock box 30, an accommodating cavity 31 is disposed in the lock box 30, the movable element 22 and the pushing element 21 are both disposed in the accommodating cavity 31, the movable element 22 is disposed in a longitudinal direction of the lock box 30, and the pushing element 21 is disposed in a transverse direction of the lock box 30. Thus, when acting force is applied to the pushing member 21, the lock box 30 can provide a force acting point for the hand, and the user experience is improved; moreover, the lock box 30 has various appearances, and can meet different requirements of users.

In the present embodiment, the lock box 30 is rectangular parallelepiped, and it is understood that in other embodiments, the lock box 30 can be designed to have various appearances according to the requirements of different users, and is not limited herein.

Referring to fig. 2, in an embodiment of the present invention, the pushing member 21 includes a connecting wall 211 and a pressing wall 212 disposed opposite to each other, and a bottom wall 213 disposed between the connecting wall 211 and the pressing wall 212, the stopper 24 is protruded on the bottom wall 213, and the movable member 22 is disposed between the connecting wall 211 and the pressing wall 212. The pressing wall 212 provides a large force application area and a small pressure on the hand of a person, and the design of the human hand can improve the convenience of opening and closing the locking device 100.

In the embodiment, the pushing member 21 is U-shaped, and the limiting member 24 is protruded from a surface of the bottom wall 213 facing the top of the lock box 30. It is understood that the pushing member 21 may have an inverted U-shape, and the retaining member 24 is protruded from the bottom wall 213 toward the bottom of the lock case 30. In other embodiments, the pusher 21 further includes a top wall (not shown), and the movable member 22 is disposed between the top wall and the bottom wall 213.

It is understood that the pressing wall 211 and the connecting wall 212 may be omitted, and are not limited thereto.

In an embodiment of the present invention, the locking device 100 further includes an elastic member 40, one end of the elastic member 40 abuts against the connecting wall 211, and the other end abuts against the inner sidewall of the lock box 30. Thus, when the pushing member 21 is forced to move and drives the movable member 22 to move towards the lock box 30 through the limiting member 24, the elastic member 40 is compressed and deformed; when the external force acting on the pushing member 21 is removed, the elastic member 40 recovers the deformation and drives the pushing member 21 to reset, and the pushing member 21 drives the movable member 22 to move toward the fixed member 10 through the limiting member 24, so that the locking device 100 can be in the locking state without the external force.

In the present embodiment, the elastic member 40 is a coil spring. It is understood that in other embodiments, the elastic member 40 may be made of other materials with deformation restoring force, such as rubber.
