[0050] Currently, the commonly used transmission locking components for screen window locks require drilling holes and chamfering in the profiles, and include at least a handle, aluminum rod, and locking components. This results in numerous parts, high costs, complex processing, and slow installation. Similarly, the commonly used single-point locking devices also require drilling holes in the profiles. The drilling holes for various single-point locks are different, making processing complex, adjustment inconsistent, and there is a risk of scrapping if the wrong hole is drilled. In addition, single-point locks are exposed on the product surface, affecting the overall aesthetics.

The door and window locking assembly of this embodiment includes a first base block 2 with a locking groove 21 and a second base block 3 with a locking post 31. The first base block 2 is disposed at the first outer side 111 or the second outer side 121, and the second base block 3 is disposed at the second outer side 121 or the first outer side 111. Specifically, the first base block 2 can be rotatably disposed at the first outer side 111, and the second base block 3 can be disposed at the second outer side 121; or, the first base block 2 can also be rotatably disposed at... The second base block 3 is disposed on the first outer side 111 at the second outer side 121; or, the first base block 2 can be disposed on the first outer side 111, and the second base block 3 can be rotatably disposed on the second outer side 121. The locking groove 21 of this embodiment has a sliding section 211, a sliding section 212, and a locking section 213 located between the sliding section 211 and the sliding section 212. When closed, a force is applied to the fan body 12 toward the frame 11, and the locking pin 31 can lock along the sliding section 211 to the locking section 213, thereby locking the frame 11 and the fan body 12. When opened, a force is applied to the fan body 12 toward the frame 11, and the locking pin 31 can unlock from the locking section 213 and pop out along the sliding section 212, thereby unlocking the frame 11 and the fan body 12.

[0056] The door and window locking assembly of this embodiment does not require processing of the profile during assembly, which solves the problem of complex profile processing during lock installation and reduces the installation difficulty. At the same time, the door and window locking assembly is hidden between the first outer side 111 and the second outer side 121, which improves the aesthetics of the exposed surface of the profile.

[0057] In some embodiments, the locking section 213 includes a first segment 2131 and a second segment 2132 arranged in a V shape. The openings of the first segment 2131 and the second segment 2132 form a V shape that faces away from the locking post 31.

The second reset elastic member 72 is disposed inside the second housing 71 and connected to the second base block 3, which allows the second base block 3 to be reset to the second preset position. In the second preset position, the sliding section 2... The locking pin 31 faces the opening of the fan body 12. When pressed, the locking pin 31 enters the sliding section 211. After the locking pin 31 is locked at the connection between the first section 2131 and the second section 2132, when pressed, the connection between the first section 2131 and the second section 2132 is located on the side of the locking pin 31 facing the sliding section 211. This ensures that the first base block 2 rotates at this time, so that the locking pin 31 enters the sliding section 212 through the second section 2132, thereby unlocking the frame 11 and the fan body 12.

[0073] In some embodiments, the second housing 71 includes a bottom housing 711 and an upper housing 712 fastened to the bottom housing 711, and a second clearance groove 7111 is formed on the bottom housing 711; the door and window locking assembly also includes a third shaft 713 disposed on the upper housing 712 facing the bottom housing 711, the second base block 3 has a third shaft hole 33, the third shaft 713 passes through the third shaft hole 33, so that the second base block 3 is rotatably disposed in the second housing 71, the second reset elastic member 72 is connected to both the third shaft 713 and the second base block 3, and the second base block 3 is reset to a second preset position through the interaction between the second reset elastic member 72, the third shaft 713 and the second base block 3.

[0074] In some embodiments, the second housing 71 includes a bottom housing 711 and an upper housing 712 that is fastened to the bottom housing 711. A second clearance groove 7111 is formed on the bottom housing 711. The upper housing 712 has a second telescopic opening 7121 on the side facing the frame 11. The door and window locking assembly also includes a third elastic member 73 and a top rod 74. In this embodiment, by setting the top rod 74 in the upper housing 712 through the second telescopic opening 7121 and clamping the third elastic member 73 between the top rod 74 and the inner wall of the upper housing 712, the side of the top rod 74 facing the second telescopic opening 7121 can abut against the first base block 2, thereby causing the locking pin 31 to pop out from the sliding section 212.

[0075] The door and window locking assembly of this utility model can simultaneously solve the shortcomings of existing transmission locking assemblies and single-point locks. It has a built-in locking pop-out function, eliminating the need for external handles and drilling holes, thus ensuring overall aesthetics. The screw fixing method also allows the door and window locking assembly of this utility model to be installed in any position without the need for slotting, eliminating the need for profile processing, making adjustment convenient and improving installation efficiency.
