Referring to fig. 1 to 7, specifically, the wind brace 10 includes a sliding rail 100, a swing rod 200, a sliding block 300, a locking block 400, and a thrust assembly 500. Wherein, the slide rail 100 is installed on the window frame, one end of the swing link 200 is rotatably connected with the window sash, and the other end is rotatably connected with the slider 300. The slider 300 is slidably connected to the slide rail 100. The locking block 400 and the pushing assembly 500 are both disposed on the slider 300, and can slide along with the slider 300, and can cooperate to lock the slider 300 on the sliding rail 100, so that the opening angle of the window sash relative to the window frame is locked.

As shown in fig. 3 and 4, the locking block 400 further includes a supporting portion 410 and a limiting portion 420 protruding from the supporting portion 410. The pushing assembly 500 elastically abuts against the abutting portion 410. The slide rail 100 is provided with a limiting opening 110, and when the locking block 400 slides to the limiting opening 110, under the elastic action of the thrust assembly 500, the locking block 400 moves relative to the slide block 300, so that the limiting portion 420 is engaged with the limiting opening 110, thereby locking the slide block 300 on the slide rail 100.

Further, the limiting portion 420 is formed in a curved surface at least in the sliding direction of the slider 300. When the window sash is subjected to a large wind pressure, the window sash can transmit the pressure to the sliding block 300 through the swing rod 200, and the sliding block 300 further acts on the locking block 400 and the thrust assembly 500 and forces the limiting part 420 to be separated from the limiting opening 110. The cambered surface design of the limiting part 420 can help the limiting part 420 to separate from the limiting opening 110, so that the sliding block 300 and the sliding rail 100 are unlocked, and the purpose of automatically closing the window sash is achieved.

Under normal conditions, above-mentioned wind brace 10 can keep the casement in fixed opening angle and realize benign ventilation, and when the wind pressure is great, can realize the self-closing of casement and avoid the risk, improves the safety in utilization of window, has also satisfied the user demand of user's pluralism simultaneously for the window uses more humanized.

In one embodiment, the slide rail 100 is provided with a sliding slot 120, and a portion of the slide block 300 is clamped in the sliding slot 120, so that the slide block 300 is slidably connected with the slide rail 100. Specifically, the sliding groove 120 is of a "T" shaped structure, and the sliding block 300 is of an "i" shape, so that some of the sliding blocks 300 can be just matched with the sliding groove 120, and the other sliding block 300 can protrude out of the sliding rail 100.

Referring to fig. 3 to 7, in one embodiment, the thrust assembly 500 includes an elastic member 510 and a moving block 520. The slider 300 is provided with a receiving groove 310, the moving block 520 and the locking block 400 are received in the receiving groove 310, and when the slider 300 is engaged with the slide rail 100, the moving block 520 and the locking block 400 are limited between the slide rail 100 and the slider 300. The slider 300 has a through hole 320, and the elastic member 510 is accommodated in the through hole 320. The through hole 320 is communicated with the receiving groove 310, so that one end of the elastic member 510 abuts against the moving block 520 and acts on the locking block 400 through the moving block 520, and meanwhile, the installation connection of the thrust assembly 500 and the locking block 400 on the slider 300 is realized.

Specifically, the elastic member 510 elastically abuts the moving block 520 against the abutting portion 410. The abutting portion 410 is formed with a first inclined surface (not shown), and the moving block 520 is formed with a second inclined surface (not shown) matching with the first inclined surface. The second inclined surface faces one side of the spacing opening 110 to provide a force for the lock block 400 to move towards the spacing opening 110. By providing the first inclined surface and the second inclined surface, the elastic force of the elastic member 510 can be decomposed into a force along the sliding direction of the slider 300 and a pushing force directed from the locking piece 400 to the limiting opening 110. Thus, when the slider 300 drives the thrust assembly 500 and the lock block 400 to slide relative to the slide rail 100 until the limiting portion 420 of the lock block 400 faces the limiting opening 110, the lock block 400 moves relative to the slider 300 toward one side of the limiting opening 110 under the action of the pushing force of the thrust assembly 500 and is clamped into the limiting opening 110.

Specifically, the through hole 320 extends in a direction away from the stopper hole 110 in a direction gradually approaching the moving block 520 in an inclined state. Thus, the pushing assembly 500 can apply a smaller pushing force to the locking block 400 toward the limiting opening 110, so as to achieve the engagement between the limiting portion 420 and the limiting opening 110. When the limiting part 420 is separated from the limiting opening 110, the window sash can be automatically closed only by overcoming the small pushing force, so that the problem that the limiting part 420 is difficult to separate from the limiting opening 110 when the pushing force is large is effectively solved.

In one embodiment, the thrust assembly 500 further includes an adjusting member 530, and the adjusting member 530 abuts against an end of the elastic member 510 away from the moving block 520 and is in threaded connection with the slider 300. By adjusting the adjusting member 530, the elastic force of the pushing assembly 500 on the lock block 400 can be changed. Further, a screw hole 330 is formed on the slider 300, the adjusting member 530 is a screw, and the adjusting member 530 is screwed with the screw hole 330. The screw hole 330 is communicated with the through hole 320, and the length of the adjusting member 530 extending into the through hole 320 can be changed by rotating the adjusting member 530, so that the extension amount of the elastic member 510 can be adjusted. Further, the axis of the screw hole 330 is arranged in line with the axis of the through hole 320, that is, the adjusting member 530 is arranged in line with the elastic member 510, so as to facilitate the adjustment of the elastic member 510 by the adjusting member 530.

In one embodiment, there are two position-limiting portions 420, and the two position-limiting portions 420 are respectively connected to two sides of the supporting portion 410, so that the locking block 400 has a U-shaped structure. Two opposite sides of the slide rail 100 are symmetrically provided with two limiting openings 110, and the two limiting parts 420 correspond to the two limiting openings 110 one by one. Thus, the moving block 520 can act on the abutting portion 410 between the two limiting portions 420, and the two limiting portions 420 are respectively matched with the two limiting openings 110, so that the locking block 400 can slide smoothly along with the slider 300, and meanwhile, effective locking between the slider 300 and the sliding rail 100 can be ensured.

Specifically, the wind brace 10 further includes an adjusting switch 600, the adjusting switch 600 is disposed on the sliding block 300, and by adjusting the adjusting switch 600, the locking block 400 can move relative to the sliding block 300 to separate the limiting portion 420 from the limiting opening 110. By arranging the adjusting switch 600, acting force can be manually applied to the locking block 400 to manually unlock the locking between the sliding block 300 and the sliding rail 100, so that the manual closing of the window sash is facilitated, and in addition, the operation is simple and easy.

In one embodiment, the slider 300 is provided with a threaded hole 340, the threaded hole 340 is communicated with the receiving groove 310, and the adjustment switch 600 is a screw and is screwed with the threaded hole 340. The adjusting switch 600 is rotated, the depth of the adjusting switch 600 screwed into the threaded hole 340 is increased, when one end of the adjusting switch 600 abuts against the abutting portion 410, the adjusting switch 600 is continuously rotated, and the adjusting switch 600 can force the locking block 400 to move relative to the sliding block 300, so that the limiting portion 420 is separated from the limiting opening 110. In other embodiments, the adjustment switch 600 may be in the form of other types of switches that can disengage the stop portion 420 from the stop opening 110.

Specifically, in the embodiment where the lock block 400 has two position-limiting portions 420, the adjusting switch 600 corresponds to the middle position of the two position-limiting portions 420, so as to achieve smooth adjustment of the lock block 400. In addition, two clamping holes 350 are formed in the slider 300, the two clamping holes 350 are located on the portion of the slider 300 protruding from the slide rail 100, and the two clamping holes 350 correspond to the two limiting portions 420 one to one. When the lock block 400 slides with the slider 300, the stopper 420 is lower than the inner wall surface of the slide groove 120. When the position-limiting portion 420 faces the two position-limiting openings 110, the position-limiting portion 420 extends into the position-limiting openings 110 to engage with the position-limiting openings 110, and at this time, a part of the position-limiting portion 420 extends into the engaging hole 350. It can be understood that, since the wall thickness of the slide rail 100 is often thin, that is, the depth of the limiting opening 110 is shallow, by providing the locking hole 350, the locking block 400 can effectively lock between the slider 300 and the slide rail 100, and the locking failure caused by the too shallow locking height between the limiting portion 420 and the limiting opening 110 is avoided.

In one embodiment, the plurality of limiting openings 110 are provided, and the plurality of limiting openings 110 are disposed at intervals along the relative sliding direction of the slide rail 100 and the slide block 300. Thus, along with the sliding of the sliding block 300 on the sliding rail 100, the locking block 400 is engaged with the limiting openings 110 at different positions, so that the window sash can reach different opening angles, and the window has a multi-angle opening function, and meets the use requirements of various opening angles of users.

Referring to fig. 1 to 3 again, specifically, the wind brace 10 further includes a fixing block 700, the fixing block 700 is located at an end of the swing rod 200 far away from the slider 300 and is rotatably connected to the swing rod 200, and the window sash is connected to the fixing block 700. A rivet 710 is inserted through the swing rod 200 and a washer 720 and then connected to the fixing block 700, thereby rotatably connecting the fixing block 700 to the swing rod 200. In addition, the slider 300 is provided with an unthreaded hole 360, and a rivet 210 penetrates through the unthreaded hole and is connected with the swing rod 200, so that the swing rod 200 is rotatably connected with the slider 300. In other embodiments, the swing link 200 may be connected to the window frame, and the slide rail 100 may be connected to the window sash, so as to achieve the same technical effects.

Specifically, the wind brace 10 includes a front end limiting block 800 and a stop limiting block 900, and the front end limiting block 800 and the stop limiting block 900 are respectively disposed at two ends of the sliding rail 100 and respectively fixed to the window frame. When the slider 300 slides to both ends of the slide rail 100, the slider 300 can abut against the front end stopper 800 and the end stopper 900, respectively, so as to avoid being separated from the slide rail 100. Further, when the window sash is in a closed state, the slider 300 abuts against the stop block 900, and when the window sash is in a maximum open state, the slider 300 abuts against the front end stop block 800. Further, a notch 910 is disposed on one side of the stop block 900 facing the slider 300. Since the adjusting member 530 is disposed on the side of the slider 300 facing the end stop 900, when the adjusting member 530 protrudes out of the slider 300, a portion of the adjusting member 530 can be received in the notch 910, so as to achieve complete closing of the window sash.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
