Door and window panel strips 3 are fixed to the sides of the latch base shell and the latch face cover by screws. In this embodiment, the above structures are all conventional structures of the prior art, and are simply applied, so they are not described in detail. The door and window panel strip is C-shaped, which facilitates the telescopic adjustment of the first latch and the second latch.

[0038] Furthermore, in this embodiment, the bottom shell of the pin is provided with a drive structure 4, a first transmission bar 5, a second transmission bar 6, a first pin 7, and a second pin 8; in this embodiment, the drive structure includes a drive motor 41, a gearbox 42 movably connected to the main shaft of the drive motor, and a drive gear 43 fixed on the gearbox, and a transmission gear 44 meshing on the drive gear; wherein the transmission gear is a double-layer gear, the large gear at its top meshes with the drive gear, and the transmission gear meshes with the tooth grooves of the first transmission bar and the second transmission bar.

[0039] During assembly, the drive structure is fixed inside the pin base, and both the first and second transmission bars are connected to the drive structure. The first and second pins are located at both ends of the door / window panel strip, with one end of the first pin connected to the first transmission bar and one end of the second pin connected to the second transmission bar. The first and second transmission bars synchronously drive the first and second pins to extend and retract within the door / window panel strip. When the drive motor rotates forward, the first and second transmission bars move up and down, extending out of the door / window panel strip to complete the locking operation. When the drive motor rotates in reverse, the first and second transmission bars move down and up, retracting into the door / window panel strip to complete the unlocking operation.

[0040] In this embodiment, the first and second transmission bars are provided with strip-shaped toothed grooves 9 on their sides. During assembly, the first and second transmission bars are symmetrically arranged on both sides of the axis of the transmission gear, and the strip-shaped toothed grooves of the first and second transmission bars mesh with the transmission gear.

Through the above structure, the first and second transmission bars can move in opposite directions.

[0041] In practical applications, the pin base is provided with a limiting slot 10; both the first and second transmission bars are fixed with protrusions 11; during assembly, the protrusions of the first and second transmission bars are respectively set in the two limiting slots, and the first and second transmission bars are translated and stopped at the ends of the limiting slots by the protrusions. This structure ensures that the translation distance is limited and does not become excessive. Furthermore, in practical applications, magnets can be embedded for limiting during translation.

[0042] For manual operation in case of power failure, a separation rocker arm 12 is provided at the connection between the gearbox and the drive motor; a manual disengagement / engagement pressing hole 13 is provided on the door / window panel strip, and a manual disengagement / engagement motor piece 14 is provided between the separation rocker arm and the manual disengagement / engagement pressing hole; the end of the manual disengagement / engagement motor piece is provided with an inclined surface, and one bottom surface of the separation rocker arm is attached to the inclined surface; when the manual disengagement / engagement motor piece is pressed inward, the separation rocker arm is raised to achieve manual disengagement / engagement control. A manual sliding groove 15 is provided on the side of the door / window panel strip; and a manual control sliding block 16 connected to the first or second transmission bar is provided in the manual sliding groove. This structure enables electromechanical separation, and corresponding tools can be used to manually control the sliding block to achieve locking or unlocking operations, improving ease of use and meeting the needs of different situations.

[0043] Furthermore, in practical applications, a pin tension assist spring 17 is provided between the second or first transmission bar and the pin base. Both the first and second transmission bars have U-shaped grooves 18 at their ends; the ends of the first and second pins are integrally bent with locking protrusions 19. During assembly, the locking protrusions of the first pins respectively engage with the U-shaped grooves of the first transmission bar, and the locking protrusions of the second pins respectively engage with the U-shaped grooves of the second transmission bar. This structure ensures the convenience and effectiveness of connection and assembly.

Its pin bottom shell is provided with a drive structure, a first transmission bar, a second transmission bar, a first pin and a second pin. In use, the extension and retraction control of the first pin and the second pin can be realized through the drive structure, which improves the stability and convenience of control, and also improves the safety of use.

[0045] Furthermore, the drive structure includes a drive motor, a gearbox, and a drive gear. The drive gear meshes with a transmission gear, and the sides of the first and second transmission bars are provided with strip-shaped toothed grooves. Through gear drive, the smoothness and stability of the drive can be guaranteed, and it has strong applicability.

[0046] Furthermore, a separation rocker is provided at the connection between the gearbox and the drive motor; a manual disengagement motor plate is provided between the separation rocker and the manual disengagement pressing hole, which, together with the manual control sliding block, enables manual control operation, thus meeting the needs of different situations and improving its applicability.
