The utility model has the beneficial effects that: the lock box for the curtain wall window is simple in structure and convenient to use, and after the gear is driven to rotate by the operating part, the gear and the pull rods are meshed with each other, so that the gear can drive the pair of pull rods to synchronously and reversely move, and finally the drive rod is utilized to control the curtain wall window to be locked and unlocked. The pin shaft on the pull rod can be in sliding fit with the guide groove so as to guide the pull rod to linearly translate and slide, and meanwhile, the pin shaft can also be connected with the transmission rod so as to control the transmission rod to move.

Preferably, the box body comprises a shell and a cover plate, and the shell and the cover plate are riveted through riveting points.

Preferably, the inside shaping of box body has the boss that surrounds gear both sides, the riveting point between casing and the apron sets up in the box body four corners and boss department. The boss can carry out spacing function of avoiding the gear to influence the lock box in the inside dislocation of box body to the gear, secondly set up the riveting point in the box body four corners and boss department can make between casing and the apron stable connection improve structural stability.

Preferably, the surface of the box body is formed with a convex strip. The convex strip can be used for the installation and the positioning of the lock box, so that the lock box can be quickly positioned when being installed on the section bar.

Preferably, the pull rod is formed with a tooth groove engaged with the gear. The toothed grooves can be used for realizing the mutual meshing between the pull rod and the gear.
