Referring to fig. 1 to 6, in a first embodiment, a door and window locking device includes a lock body 100, where the lock body 100 includes a housing 110, a bottom cover 120, and a face cover 130, a cavity 200 is formed in the housing 110, a pull handle 300 is disposed in front of the cavity 200, and the pull handle 300 is coupled to the lock body 100; a locking mechanism 400 is arranged behind the cavity 200, the locking mechanism 400 includes a first locking tongue 410 and a second locking tongue 420, the middle portions of the first locking tongue 410 and the second locking tongue 420 are both hinged to the lock body 100, a locking groove 430 is formed between the head end of the first locking tongue 410 and the head end of the second locking tongue 420, the locking mechanism 400 further includes a return spring 440, and both ends of the return spring 440 are respectively connected to the first locking tongue 410 and the second locking tongue 420;

the tail end of the first bolt 410 is connected with the tail end of the second bolt 420 through a linkage structure; the first bolt 410 comprises a convex block 411, the end of the convex block 411 is arc-shaped, the second bolt 420 comprises a body 421, a protruding block 422 is arranged on the body 421, a groove 423 is formed between the body 421 and the protruding block 422, the groove 423 comprises a guide surface 424, the end of the convex block 411 is abutted to the guide surface 424 of the groove 423, and the convex block 411 and the groove 423 jointly form the linkage structure.

The lower part of the handle 300 is coupled to the lock body 100 through a rotating shaft 310, and the axis of the rotating shaft 310 is in the left-right direction; the back of the handle 300 is provided with a pin 320, the pin 320 is located below the rotating shaft 310, the axis of the pin 320 is parallel to the axis of the rotating shaft 310, the first locking tongue 410 is provided with a guide block 412 extending forward, the guide block 412 is provided with an inclined guide surface 413, and the pin 320 is in contact with the guide surface 413. A second torsion spring 510 is disposed between the blocking cover 500 and the lock body 100. A first torsion spring 330 is sleeved on the pin 320, one end of the first torsion spring 330 abuts against the pull handle 300, and the other end abuts against the lock body 100. The handle 100 is located at the lower part of the cavity 200, a blocking cover 500 is arranged at the upper part of the cavity 200, the blocking cover 500 is hinged to the lock body 100, and the lower edge of the blocking cover 500 is close to the upper edge of the handle 300.

This locking device is when assembling, installs locking mechanical system 400 in the cavity earlier, and in this embodiment, two spring bolts articulate in the lock body through different pins respectively. Then, a return spring 440 is installed in the two lock tongues, and the head ends of the two lock tongues are brought close to each other by the return spring. And the handle 300 is hidden in the cavity. The surface of the handle is substantially flush with the surface of the face cover 130 and the flap cover 500.

Referring to fig. 7B, the head ends of the two lock tongues are close to each other, so that the width of the locking groove 430 is small, and the hook body on the door or window abuts against the two lock tongues simultaneously, thereby playing a locking effect.

When the unlocking is required, a user pushes the blocking cover 500 backwards with fingers, then the fingers can hook the upper part of the handle 300, and then the handle 300 is pulled forwards with force, because the lower part of the handle 300 is hinged with the lock body 100 through the rotating shaft 310, when the upper part of the handle 300 rotates forwards, the lower part of the handle 300 rotates backwards, the pin shaft 320 moves upwards from the bottom, and because the pin shaft 320 supports against the guide block 412 of the first lock tongue 410, the pin shaft 320 drives the first lock tongue 410 to rotate when turning upwards.

Referring to fig. 6 and 7A, when the pin 320 moves upward, the tail end of the first latch 410 also synchronously rotates upward, and the head end rotates relatively downward; since the protrusion 411 of the first latch 410 abuts against the second latch 420, when the first latch 410 rotates, the second latch 420 also synchronously rotates, and the head end of the second latch rotates upward relatively.

Since the second locking tongue is installed above the first locking tongue, when the handle 300 is rotated forward, referring to fig. 7A, the width of the locking groove 430 is increased, and when the width of the locking groove 430 is greater than that of the hook, the hook on the door or window is separated from the two locking tongues at the same time, so that unlocking is achieved.

When the external force disappears, the first torsion spring, the second torsion spring and the return spring 400 act. The two lock tongues reset, and the handle and the blocking cover also reset simultaneously. The handle and the blocking cover after reset can just block the cavity.

When the lock needs to be locked, the lock locker is only required to be close to the hook body, the hook body is utilized to jack the two lock tongues, and the elastic force of the reset spring is overcome, so that the two lock tongues can hook the hook body again.

Referring to fig. 8, the present invention also provides a sliding door and window, including a window frame, a first movable window sash and a second movable window sash, where the first movable window sash includes a first installation section 10, the first installation section is arranged in the vertical direction, and the side surface of the first installation section 10 is installed with the door and window locking device; the second movable sash window comprises a second mounting section bar 20, the second mounting section bar is arranged in the vertical direction, and a hook body matched with the door and window locking device is arranged on the second section bar.

By installing the locking device on the side face of the section bar, when unlocking is carried out, due to the fact that forward force is needed, the window opening action can be synchronously achieved after unlocking is achieved through the forward force. Thereby making the windowing simpler and more convenient.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the utility model as set forth in the claims appended hereto.
