[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] like Figures 1-6 As shown, an unlocking actuator for doors and windows includes a housing, which is cuboid in shape and has an internal installation space. The housing includes a cover 1 with an opening on one side and a base plate 2 detachably disposed at the opening. A boss 11 is provided on the side of the cover 1 opposite to the base plate 2, and a first through hole 12 is provided on the boss 11.

[0025] Two racks 4 and a gear 3 are arranged within the installation space. The gear 3 is rotatably mounted within the installation space, and its axis of rotation extends along the thickness direction of the outer shell and is collinear with the axis of the first through hole 12. The two racks 4 extend along the length direction of the outer shell and move back and forth along the length direction. Both racks 4 mesh with the gear 3 and are symmetrically arranged relative to the axis of rotation of the gear 3. When the gear 3 rotates, it can drive the two racks 4 to move synchronously towards each other or away from each other. A transmission post 5 is provided at the end of each rack 4 away from the gear 3. When viewed along the length direction of the outer shell, the two transmission posts 5 are aligned. A strip hole 13 is provided on the side of the cover 1 away from the bottom plate 2 and at the position corresponding to the two transmission posts 5. The transmission post 5 passes through the corresponding strip hole 13 and can move back and forth within the length range of the strip hole 13 under the drive of the gear 3. The transmission post 5 is used to connect with other unlocking mechanisms on doors and windows. The movement of the transmission post 5 can drive the corresponding mechanism to unlock.

[0026] Preferably, the gear 3 is provided with a first operating hole 31. The cross-section of the first operating hole 31 is non-circular, preferably square. An operating handle or the like can be inserted into the first operating hole 31. The rotation control of the gear 3 can be achieved through the operating handle, thereby achieving motion control of the transmission column 5.

[0027] Preferably, a second through hole 21 is provided on the base plate 2 at a position corresponding to the first operating hole 31. The axis of the second through hole 21 is collinear with the axis of the first through hole 12, and both have the same diameter. The two ends of the gear 3 are respectively inserted into the first through hole 12 and the second through hole 21, which can limit the movement of the gear 3.

[0028] Further, in the thickness direction of the housing, the size of the rack 4 is equal to the size of the mounting space, that is, the rack 4 will not be shaken in the thickness direction. Preferably, in the thickness direction, the tooth groove of the rack 4 is blocked near the side of the bottom plate 2, the size of the tooth on the gear 3 is equal to the size of the tooth groove on the rack 4, and the side of the tooth groove of the rack 4 away from the bottom plate 2 is blocked by the housing 1, that is, the gear 4 is limited by the rack 4 and the housing 1 in the thickness direction.

[0029] Preferably, a clamping groove 14 is arranged between the two sides of the boss 11 along the width direction of the cuboid and the housing 1, and the clamping groove 14 penetrates the boss 11 along the length direction. Two threaded holes 15 are arranged on the boss 11, and the two threaded holes 15 are symmetrically arranged relative to the axis of the first through hole 12. A bolt 17 is arranged in each threaded hole 15. A third through hole 16 is arranged on the bottom plate 2 at a position corresponding to each threaded hole 15, and the third through hole 16 can be used to operate the bolt 17. During installation, an inverted T-shaped groove is formed at the installation position of the door or window, the boss 11 can be placed into the T-shaped groove, and the cross section of the T-shaped groove matches the cross section of the boss 11. The upper side wall of the T-shaped groove can be inserted into the clamping groove 14, as shown in Figure 6 By screwing the bolt 17, the end surface of the bolt 17 can abut against the bottom of the T-shaped groove, thereby achieving the fixed connection of the unlocking transmission and the door and window.

[0030] Preferably, two second operation holes 17 are further arranged on the boss 11, and the two second operation holes 17 are symmetrically arranged relative to the axis of the first through hole 12. Two third operation holes 22 are arranged on the bottom plate 2, and the two third operation holes 22 are aligned with the two second operation holes 17 one by one. In practice, there will be a bolt or the like at a position corresponding to the second operation hole 17 on the door and window. The second operation hole 17 and the third operation hole 22 facilitate the operation of the corresponding structure on the door and window.
