Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1 and 2, the wind brace in the present embodiment includes a first member 1 for connecting a window sash 4, a second member 2 for connecting a window frame 5, respectively, and a link 3 having both ends hinged to the first member 1 and the second member 2, respectively.

The first assembly 1 in this embodiment includes a housing, a first rack 12, a second rack 13, a slider 16, a gear 14, and a driving assembly.

The housing includes a bottom cover 113 and a housing main body 114, and the bottom cover 113 is connected to the housing main body 114 by a screw. The case is assembled by the bottom cover 113 and the case main body 114 in a split structure, which can be assembled and combined easily. The housing is further formed with a runner 112 extending in the longitudinal direction. In this embodiment the housing is fixedly mounted to the upper side of the sash 4 so that its length direction is parallel to the upper side of the sash 4.

The connecting rod 3 and the gear 14 can synchronously move along the length direction of the shell relative to the shell, specifically, the gear 14 is rotationally connected with the sliding seat 16, meanwhile, the connecting rod 3 is pivoted with the sliding seat 16, and the gear 14 and the connecting rod 3 can synchronously translate and slide through the sliding seat 16. The pivot shaft between the connecting rod 3 and the sliding seat 16 is in sliding fit with the sliding groove 112, and the sliding seat 16 can be guided to slide along the length direction of the shell through the sliding groove 112.

The first rack 12 and the second rack 13 extend along the length direction of the shell, the gear 14 is located between the first rack 12 and the second rack 13, the second rack 13 is meshed with the gear 14, and the driving assembly is used for driving the first rack 12 to be meshed with or separated from the gear 14. Specifically, the driving assembly includes a traction seat 151, a traction shaft 152, and a return spring 153, where the traction seat 151 moves along the length direction of the housing, one end of the traction shaft 152 is connected with the first rack 12, the other end of the traction shaft 152 forms a sliding fit with the traction seat 151 in the length direction, and the return spring 153 is used to drive the traction shaft 152 to move in a direction away from the traction seat 151. In this embodiment, the traction seat 151 is linked with the handle, and the traction seat 151 is driven to move along the length direction of the housing by operating the handle. The first rack 12 is formed with a horizontal guide groove 18, the horizontal guide groove 18 extends in a direction of the first rack 12 away from and approaching the gear 14, and the traction shaft 152 is provided with a protruding column 154 slidably engaged with the horizontal guide groove 18. The casing is formed with an oblique guide groove 17, and meanwhile, the first rack 12 is fixedly connected with a protruding point 111 which is in sliding fit with the oblique guide groove 17, and when the protruding point 111 moves to two end points of the oblique guide groove 17 respectively, the first rack 12 is meshed with and separated from the gear 14 respectively. When the first rack gear 12 receives a pushing force in the longitudinal direction from the driving assembly, the first rack gear 12 moves along the diagonal guide groove 17 due to the cooperation of the diagonal guide groove 17 and the protruding point 111, and thereby is switched to a state of being engaged with and disengaged from the gear 14, respectively.

The mode of use of the stroke brace in this embodiment is as follows:

referring to fig. 3, the unlock mode: the traction seat 151 is driven to move away from the first rack 12 by rotating the handle, at this time, the first rack 12 is driven to move by the traction shaft 152, and the salient point 111 of the first rack moves to the first end point of the oblique guide groove 17 relatively, at this time, the first rack 12 moves away from the gear 14 and is separated from the gear 14. The gear 14 is only meshed with the second rack 13, the sliding seat 16 can slide freely along the shell without limitation, and the window sash 4 can be opened and closed freely.

Referring to fig. 4, the lock mode: the traction seat 151 is driven to move towards the direction approaching to the first rack 12 by rotating the handle, and at this time, the first rack 12 is driven to move by the traction shaft 152, and the salient point 111 of the first rack relatively slides to the second end point of the oblique guide groove 17. At this time, the second rack 13 moves in a direction approaching to the gear 14 and finally meshes with the gear 14, at this time, the gear 14 simultaneously meshes with the second rack 13 and the second rack 13, the gear 14 cannot rotate, the slide carriage 16 and the connecting rod 3 are simultaneously limited by the gear 14 and cannot move along the length direction of the housing, and the slide carriage 16 and the connecting rod 3 must slide during the opening and closing process of the window sash 4, so that the window sash 4 cannot be further opened and closed when the slide cannot slide, and thus is locked.

Referring to fig. 5, the automatic unlock mode: when the wind brace is in the locking mode, when the window sash 4 is driven to be closed by strong wind blowing or manual pushing and other strong external force, the connecting rod 3 is subjected to corresponding force and is transmitted to the sliding seat 16 to enable the sliding seat 16 to slide along the closing direction of the window sash 4, when the force is applied to a certain extent, the locking effect of the first rack 12 on the gear 14 is broken, the gear 14 is utilized to reversely drive the first rack 12 to move in the direction away from the gear 14, and due to sliding fit between the traction seat 151 and the traction shaft 152, even under the condition that the traction seat 151 does not move, self-unlocking can be realized when the window sash 4 is driven by strong external force such as wind blowing, namely, the gear 14 rotates under the action of strong external force and drives the first rack 12 to reversely move to realize unlocking, so that the window sash 4 is protected. Meanwhile, because the horizontal guide groove 18 is in sliding fit with the convex column 154, the traction shaft 152 and the first rack 12 can slide in the extending direction of the horizontal guide groove 18, when the window sash 4 is unlocked by strong external force, the movement of the window sash is not limited in the extending direction, so that the traction shaft 152 can slide relative to the traction seat 151 to realize the self-unlocking function.

The above-described embodiments are merely preferred embodiments of the present utility model, and are not intended to limit the present utility model in any way. Any person skilled in the art can make many more possible variations and modifications of the technical solution of the present utility model or modify equivalent embodiments without departing from the scope of the technical solution of the present utility model by using the technical content disclosed above. Therefore, all equivalent changes according to the inventive concept are covered by the protection scope of the utility model without departing from the technical scheme of the utility model.
