Referring to fig. 1, fig. 1 is a schematic view showing two states of an automatic locking apparatus. The automatic locking device comprises a first lock seat 100 and a second lock seat 200, wherein when the first lock seat 100 is arranged on a fixed frame 300 of a door and window, the second lock seat 200 is arranged on a movable sash 400 of the door and window; when the first lock holder 100 is disposed on the movable sash 400 of the door and window, the second lock holder 200 is disposed on the fixed frame 300 of the door and window. The first lock holder 100 and the second lock holder 200 are used in cooperation, so that the door and window can be automatically locked after being closed under the pushing of external force such as wind, and can be opened again only when being actively operated by a user.

In one embodiment, the first lock holder 100 includes a first holder body 110, a tilt bolt 120, and a first elastic member 130.

For example, the first base 110 is directly fixed on the fixed frame 300, the tilt-bolt 120 is slidably disposed on the first base 110, and the first elastic member 130 is elastically supported between the first base 110 and the tilt-bolt 120, the second lock base 200 includes a second base 210, a slider 220, and a second elastic member 230, the slider 220 is provided with a lock slot 221 for receiving the tilt-bolt 120, for example, the second base 210 is slidably disposed on the movable fan 400, and the second base 210 can slide up and down in the state shown in fig. 1, for example, the second base 210 can move to a first position and a second position relative to the movable fan 400, the left side in fig. 1 is a state diagram of the second base 210 in the first position relative to the movable fan 400, and the right side in fig. 1 is a state diagram of the second base 210 in the second position relative to the movable fan 400, that is, the first position and the second position are two positions of the relative movement of the second base 210, the first position is located above the second position, and a vertical distance L (i.e., a sliding stroke) between the first position and the second position of the second base 210 is shown in fig. 1.

The sliding block 220 is slidably disposed on the second seat 210, specifically, the sliding direction of the sliding block 220 is also along the up-down direction shown in fig. 1, the sliding block 220 can slide to a third position and a fourth position relative to the second seat 210, and the third position and the fourth position are two positions of relative movement of the sliding block 220, that is, the third position is located above the fourth position. The second elastic member 230 is used for driving the sliding block 220 to move from the third position to the fourth position. Fig. 1 shows a schematic structural diagram of the second seat 210 in a state of the first position and the slide 220 in the fourth position on the left side; fig. 1 shows a schematic structural diagram of the second seat 210 at the second position and the slide 220 at the third position. Fig. 2 shows a schematic structural diagram of the second seat 210 in the second position and the slide 220 in the fourth position. When the door and window does not need to be automatically locked, referring to the structure on the left side in fig. 1, at this time, the second seat 210 is at the first position, and the sliding block 220 is at the fourth position, that is, the fixed frame 300 and the movable sash 400 can be freely opened and closed (opened and closed in the direction perpendicular to the paper surface of fig. 1). When the door and window is closed, the second seat 210 is slid downwards to the state shown on the right side in fig. 1, and at this time, the second seat 210 is in the second position, and the slider 220 is in the third position, as can be seen from the figure, the second elastic member 230 in this embodiment is in a compressed state, it is easy to think that if the door and window is opened at this time (the fixed frame 300 and the movable sash 400 rotate in a direction perpendicular to the paper surface of fig. 1), at this time, under the action of the second elastic member 230, the slider 220 will slide downwards, that is, the slider 220 will have the third position to slide to the fourth position, at this time, the position of the slider 220 can accommodate the latch bolt in the lock slot 221, the state shown in fig. 2 is after the door and window is closed, if the door and window is closed under the external force at this time, the inclined latch bolt 120 first collides with the slider 220, the inclined latch bolt 120 moves towards the direction away from the slider 220 to compress the first elastic member 130 so, when the door and window is completely closed, that is, when the second base 210 is located at the second position and the sliding block 220 is located at the fourth position, the inclined bolt 120 can be accommodated in the locking groove 221, so that automatic locking is achieved. Therefore, when the door and window is closed, the automatic locking device can be started, so that the door and window can be automatically locked when being closed next time.

In one embodiment, the automatic locking device further comprises a driving member (not shown) for driving the second seat 210 to move between the first position and the second position. The drive element can be, for example, a lever handle.

Further, the inclined bolt 120 includes a first straight-tongue surface 122, the first straight-tongue surface 122 is adjacent to the first inclined-tongue surface 121, and referring to fig. 1, the first straight-tongue surface 122 is used for interfering with the sliding block 220 to drive the sliding block 220 to move relative to the second holder 210 so as to compress the second elastic element 230. Further, the inclined bolt 120 further includes a second inclined bolt surface 123 (see fig. 1 and 3), and the second inclined bolt surface 123 is disposed opposite to the first straight bolt surface 122. Referring to fig. 2, when the second seat 210 moves from the second position to the first position, that is, when the second seat 210 moves upward from the second position shown in fig. 2 to the first position of the left side of fig. 1, the sliding block 220 abuts against the second inclined tongue surface 123 to move the inclined tongue 120 in a direction away from the sliding block 220 (the inclined tongue 120 retracts into the accommodating cavity 111) to compress the first elastic element 130, and when the second seat 210 moves upward to be out of contact with the inclined tongue 120, the first elastic element 130 ejects the inclined tongue 120 again.
