The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, in one embodiment, a closure 10 is provided, the closure 10 being mountable to a door or window such that the door or window can be automatically locked. Taking the example that the locking device 10 is installed on a window, the locking device 10 includes a lock catch 200 and a locking mechanism 100, the lock catch 200 may be installed on a window frame, the locking mechanism 100 may be installed on a window sash, when the locking mechanism 100 located on the window sash encounters an emergency such as strong wind, the window sash is closed towards one side of the window frame under the influence of the environment, and at this time, the lock catch 200 may be matched with the locking mechanism 100 to lock, so that the window sash and the window frame are automatically locked. In an embodiment, the locking mechanism 100 includes a base 110, a sliding plate 120 and an elastic member 130, the base 110 is approximately rectangular, the sliding plate 120 is also approximately rectangular, and the size of the sliding plate 120 may be smaller than the size of the base 110, so that the sliding plate 120 may slide on the surface of the base 110. The elastic member 130 has one end abutting against the base 110 and the other end abutting against the sliding plate 120, wherein the elastic member 130 may be a member capable of realizing elastic deformation, such as a spring, and the sliding plate 120 may press the elastic member 130 when the sliding plate 120 slides in the base 110 toward the forward direction. Specifically, when the sliding plate 120 slides in the forward direction relative to the base 110, the forward direction is slightly deviated from the vertical direction of the base 110, i.e., the forward direction may be a direction in which the vertical direction rotates counterclockwise by about 6 degrees, which may prevent the latch 200 from being self-locked to the locking mechanism 100, i.e., prevent the latch 200 from being unable to push the sliding plate 120 to slide when contacting the locking mechanism 100. The angle between the forward direction and the vertical direction may be any angle capable of achieving the above technical effects, and is not limited to the above angle range.

Referring to fig. 3 and 4, in an embodiment, the sliding plate 120 is provided with a receiving groove 121 penetrating through a side end surface of the sliding plate 120, and the receiving groove 121 forms an opening 123 at the side end surface, the width of the opening 123 is smaller than the maximum width of the receiving groove 121, and the lock catch 200 can enter the receiving groove 121 from the opening 123, wherein a first wedge block 1231 is formed at the opening 123 of the receiving groove 121, the first wedge block 1231 is similar to an inverted triangle, the first wedge block 1231 has a first acting surface 1235 facing away from the receiving groove 121, and the first acting surface 1235 is disposed obliquely to the sliding direction of the sliding plate 120, so that the lock catch 200 can move along the first acting surface 1235. Referring to fig. 7 and fig. 8, in an embodiment, when the locking mechanism 100 approaches to the lock catch 200, the lock catch 200 may first abut against the first acting surface 1235, then move to the opening 123 along the first acting surface 1235, and during the process that the lock catch 200 moves along the first acting surface 1235 toward the opening 123, the lock catch 200 may push the sliding plate 120 to slide in the forward direction, where the process that the sliding plate 120 slides in the forward direction may compress the elastic member 130, so that the elastic member 130 deforms, and at this time, the lock catch 200 may be disengaged from the opening 123 and enter the receiving slot 121. With reference to fig. 9, further, after the lock catch 200 enters the accommodating groove 121, the sliding plate 120 loses the holding force of the lock catch 200 against the sliding plate 120, so that the elastic member 130 recovers the deformation and releases the elastic potential energy, so as to apply a force opposite to the sliding plate 120, and thus the sliding plate 120 slides reversely, and the first wedge block 1231 blocks the lock catch 200 from exiting the accommodating groove 121 from the opening 123. The reverse direction is the direction opposite to the forward direction.

The locking mechanism 100 and the locking device 10, wherein the locking mechanism 100 includes a base 110, a sliding plate 120 and an elastic member 130, a bottom plate is provided with a receiving groove 121, an opening 123 of the receiving groove 121 includes a first wedge block 1231, the first wedge block 1231 has a first acting surface 1235, the lock catch 200 can slide along the first acting surface 1235, and drives the sliding plate 120 to slide relative to the base 110, so that the lock catch 200 is received in the receiving groove 121, and when the lock catch 200 is received in the receiving groove 121, the elastic member 130 drives the sliding plate 120 to reset, so that the first wedge block 1231 blocks the lock catch 200 from falling out of the receiving groove 121. The locking mechanism 100 may be mounted on a door or a window, wherein the locking mechanism 100 may be mounted on a door leaf or a window sash, the lock catch 200 may be mounted on a door frame or a window frame, when the locking mechanism 100 encounters an emergency such as strong wind, the locking mechanism 100 moves towards one side of the lock catch 200, and at this time, the lock catch 200 slides to the accommodating groove 121 along the first acting surface 1235 and does not fall off from the accommodating groove 121, so that the lock catch 200 and the locking mechanism 100 are in a locked state, thereby realizing automatic closing of the door and the window.

Referring to fig. 3 and 5, in an embodiment, the sliding plate 120 is provided with a reset groove 127, a positioning post 129 is disposed at a bottom of the reset groove 127, meanwhile, a sliding groove may be also disposed on the base 110, the reset groove 127 is mutually communicated with the sliding groove, the elastic member 130 may be a spring, one end of the spring is sleeved on the positioning post 129, and the other end of the spring is accommodated in the sliding groove and abuts against a groove wall of the sliding groove, so that when the sliding plate 120 slides on the base 110, the sliding plate 120 may compress the elastic member 130. It can be understood that the base 110 may not be provided with a sliding groove, at this time, one side of the base may be provided with an abutting plate, one end of the spring is sleeved with the positioning post 129, and the other end of the spring may directly abut against the abutting plate of the base, so that the sliding plate 120 compresses the spring, and at this time, the lock catch 200 enters the accommodating groove 121. In one embodiment, after entering the receiving groove 121, the sliding member 120 slides reversely due to the force of the spring, so that the lock catch 200 does not separate from the receiving groove 121. Specifically, the groove wall of the accommodating groove 121 may abut against the lock catch 200, or may not abut against the lock catch 200, when the groove wall of the accommodating groove 121 abuts against the lock catch 200, the lock catch 200 is not easily separated from the accommodating groove 121 due to the abutting force, and when the groove wall of the accommodating groove 121 does not abut against the lock catch 200, the lock catch 200 is blocked by the first wedge block 1231 from being separated from the accommodating groove 121 from the opening 123. In an embodiment, the base 110 is further provided with a receiving groove 115, where the receiving groove 115 is mutually communicated with the receiving groove 121, and when the lock catch 200 can slide along the first acting surface 1235 into the receiving groove 121, the lock catch can slide to the receiving groove 115.

Referring to fig. 10, in an embodiment, the latch 200 may also be controlled by a handle of the window frame, that is, the handle may control the latch 200 to move on the window frame, and after the latch 200 enters the accommodating groove 121 through the opening 123, a user may operate the handle, so that the latch 200 may abut against a groove wall of the accommodating groove 121 to push the sliding plate 120 to slide continuously in the forward direction and compress the elastic member 130. Further, a protrusion 125 is disposed on a side of the sliding plate 120 facing the limiting member 140, and when the protrusion 125 abuts against the limiting member 140 protruding from the limiting slot 111, the force of the protrusion 120 abutting against the limiting member 140 is greater than the force of the elastic member 130 on the sliding plate 120, i.e. the protrusion 125 can limit the sliding plate 120 to slide along the opposite direction. Because the lock catch 200 is accommodated in the accommodating groove 121 and the protrusion 125 abuts against the limiting member 140, when the user releases the handle, the sliding plate 120 will not slide reversely, and the lock catch 200 is locked with the locking mechanism 100 more firmly, and the door or window can be prevented from being pried open to protect the living safety of the user.

Referring to fig. 4, 5 and 6, further, the limiting member 140 includes a limiting portion 141 and an extending portion 143 extending from opposite ends of the limiting portion 141, the limiting portion 141 is convexly disposed on the extending portion 143 toward one side of the sliding plate 120, and the shape of the limiting portion 141 is arc-shaped, such that the shape of the limiting member is similar to an arc shape.
