The inner support 1 slides in the outer support 2, and a push block 24 is provided in the outer support 2.

[0041] In this embodiment, the end of the inner support 1 is connected to a first connecting block 12, the first connecting block 12 is hinged with a first connecting plate 411, and the first connecting plate 411 is connected to the window sash profile 41; the end of the outer support 2 is connected to a second connecting block 22, the second connecting block 22 is hinged with a second connecting plate 421, and the second connecting plate 421 is connected to the window frame profile 42.

[0042] A first limiting slot 11 is formed on the outer side wall of the inner support 1, a second limiting slot 21 is formed on the outer side wall of the outer support 2, a limiting portion 342 is arranged inside the inner support 1, and the limiting portion 342 includes a stopper 31, a spring 32, a positioning pin 33, a limiting block 34, and a limiting hook 35. When the inner support 1 slides out, the push block 24 pushes the stopper 31 to pass through the first limiting slot 11 and the second limiting slot 21 in sequence, and the stopper 31 blocks the second limiting slot 21, so that the window sash profile 41 is in an open state.

[0043] In this embodiment, the outer support 2 is formed with a sliding groove 23 extending along the length direction of the outer support 2 , the inner support 1 slides in the sliding groove 23 , the push block 24 is located in the sliding groove 23 , and the second limiting notch 21 is connected to the sliding groove 23 .

[0044] In this embodiment, the push block 24 is aligned with the second limiting groove 21, and the push block 24 includes an ejection section 241 and two retraction sections 242. The retraction sections 242 are respectively arranged at the left and right ends of the ejection section 241. The ejection section 241 extends along the length direction of the outer support 2, and the retraction section 242 is inclined. The retraction section 242 is used to guide the stopper 31 to exit the second limiting groove 21 and the first limiting groove 11 in sequence.

[0045] In this embodiment, the stop block 31 is provided with a first mounting groove 311 and a second mounting groove 312, the limit block 34 is arranged on the first mounting groove 311, the positioning pin 33 is installed in the inner support 1, the positioning pin 33 is slidably matched with the stop block 31 through the second mounting groove 312, the extension direction of the second mounting groove 312 is perpendicular to the length direction of the inner support 1, one end of the positioning pin 33 is provided with a limit hook 35, and the other end is provided with a spring 32, the limit hook 35 is hooked and connected to the limit block 34, and the spring 32 is used to push the stop block 31 to retract into the inner support 1.

[0046] In this embodiment, an adjustment groove 341 is opened on the front side of the limit block 34, and the spring 32 pushes the limit hook 35 to hook the bottom end of the adjustment groove 341. A limit portion 342 is formed in the middle of the adjustment groove 341. When the push block 24 pushes the stop block 31 to extend out of the first limit groove 11, the limit hook 35 is hooked and connected to the limit portion 342, thereby limiting the stop block 31 from retracting into the inner support 1.

[0047] In this embodiment, a limiting boss 343 is formed on the back of the limiting block 34 , one end of the spring 32 abuts against the inner wall of the top-pressing inner support 1 , and the other end abuts against the top-pressing limiting boss 343 , thereby pushing the stopper 31 to retract into the inner support 1 .

[0048] In this embodiment, a baffle 13 is formed inside the inner support 1 , and the baffle 13 blocks the push block 24 to limit the maximum extent of the inner support 1 extending out of the outer support 2 .

[0049] In this embodiment, the inner support 1 and the first connecting block 12, the first connecting block 12 and the first connecting plate 411, the first connecting plate 411 and the window sash profile 41, the outer support 2 and the second connecting block 22, the second connecting block 22 and the second connecting plate 421, and the second connecting plate 421 and the window frame profile 42 are connected respectively by rivets.

[0050] In this embodiment, the specific use process is: push the window sash profile 41 to open outward, drive the inner support 1 to be lifted outward, cooperate with the first connecting block 12 to hinge the first connecting piece 411, and the second connecting block 22 to hinge the second connecting piece 421, so that the inner support 1 slides and gradually extends out of the outer support 2, at this time, the stopper 31 is located in the inner support 1, and one end of the spring 32 presses against the inner side wall of the inner support 1, and the other end presses against the limiting boss 343 of the limiting block 34, so that the stopper 31 can be pushed into the inner support 1, and the positioning pin 33 is located at the bottom end of the second mounting groove 312;

[0051] As the inner support 1 gradually slides out of the outer support 2, the block 31 and the baffle 13 gradually approach the push block 24 until the block 31 touches the retracted section 242 of the push block 24, and the block 31 gradually slides and climbs up to the ejection section 241 along the retracted section 242, so that the retracted section 242 pushes the block 31 to gradually extend out of the inner support 1 and the outer support 2 in sequence, that is, the block 31 passes through the first limiting slot 11 and the second limiting slot 21 in sequence. At this time, since the block 31 gradually extends out of the inner support 1, the spring 32 is gradually compressed to cooperate with the positioning pin 33. The slidable cooperation with the stopper 31 causes the positioning pin 33 to gradually move from the bottom end of the second mounting groove 312 to the top end, thereby driving the limiting hook 35 to slide upward in the adjusting groove 341 of the limiting block 34, until the stopper 31 moves to the ejection section 241 and slides at the ejection section 241, and the limiting hook 35 moves to the middle of the adjusting groove 341 and hooks and connects with the limiting portion 342, so that the limiting hook 35 can be hooked and connected with the limiting portion 342, so that the limiting block 31 can be limited to return to the original position and retract the inner support 1, and the spring 32 is in a compressed state;

[0052] The stopper 31 continues to slide on the ejection section 241 until the baffle 13 abuts against the retraction section 242 of the push-pushing block 24, and the window sash profile 41 opens to the maximum extent, preventing the inner support 1 from withdrawing from the outer support 2;

[0053] At this time, the window sash profile 41 can be loosened, and under the action of gravity of the window sash profile 41, the inner support 1 slides back and the window sash profile 41 gradually closes, causing the stopper 31 to slide on the second limiting slot 22 until the stopper 31 blocks the end of the second limiting slot 22, the inner support 1 stops sliding, and the window sash profile 41 stops moving, so that the window sash profile 41 is in an open state; wherein, during the sliding and retraction process of the inner support 1, the stopper 31 will slide away from the push block 24, and when the stopper 31 leaves the push block 24 and continues to slide, the limit hook 35 is hooked to the limit portion 342, which limits the stopper 31 from resetting and retracting the inner support 1, so that the stopper 31 continues to be located on the second limiting slot 22 and will not retract.

[0054] When it is necessary to close the window sash profile 41 in the opened state, the window sash profile 41 is pushed outward again to lift the inner support 1 and slide outward again, so that the stopper 31 touches the retracted section 242 of the push block 24 again, thereby disengaging the limit hook 35 from the limit portion 342. Since the limit hook 35 disengages from the limit portion 342, the spring 32 rebounds and pushes the limit hook 35 to slide back to the bottom end of the adjustment groove 341, thereby driving the stopper 31 to exit the second limit slot 21 and the first limit slot 11 in sequence until it retracts into the inner support 1. In this way, the stopper 31 will not restrict the sliding of the inner support 1, so that the inner support 1 is recovered under the gravity of the window sash profile 41, thereby closing the window sash profile 41; in this way, the window sash profile 41 is quickly opened and closed.

[0055] Among them, the setting of the baffle 13, the block 31, and the push block 24 reaches an installation error of ±4mm. Specifically, when the block 31 contacts the push block 24, the limiting component will receive the force of the push block 24. Since the limiting component as a whole moves laterally, the push block 24 contacts the straight edge of the block 31, and the distance between the push block 24 and the baffle 13 is 11, which belongs to the installable error range. When there is an installation error between this embodiment and the window sash profile 41 and the window frame profile 42, the installation error of ±4mm can be achieved.

[0056] The embodiments described above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Any technician familiar with the field can use the above disclosed technical content to make more possible changes and modifications to the technical solution of the present invention without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent and equivalent changes made according to the idea of ​​the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
