Description

Technical Field

[0001] The present application relates to the field of window technology, and in particular to a linkage window opening device. Background Art

[0002] Modern windows are composed of three parts: window frames, glass and movable components (handles, pulleys, etc.). The window frame is responsible for supporting the main structure of the window, which can be made of wood, metal, ceramic or plastic. The transparent part is attached to the window frame and can be made of paper, cloth, silk or glass. The movable components are mainly made of plastic, and the places where people touch may also be wrapped with plastic. The factory has a large number of ventilation windows in the factory building. When each ventilation window needs to be opened or closed, it takes a lot of time to close them one by one, which greatly increases the time cost.

[0003] For example, a Chinese patent (publication number: CN211370000U) discloses a linkage window opener, including a window opener, a transmission pipe and a window opening mechanism arranged along the length of the transmission pipe and corresponding to each window, the window opening mechanism including a transmission pipe bracket, a transmission pipe fixing frame and a meshing transmission gear and rack, the window opener includes a box body, a rotating handle and a commutator, the box body has a rotating through hole for the transmission pipe to pass through, the commutator is arranged in the box body, and the transmission pipe located in the box body is provided with a driven wheel matching the driving wheel; the transmission pipe fixing frame is horizontally provided with a through hole for the transmission pipe to pass through, and the hole wall of the through hole is provided with a sliding groove penetrating the transmission pipe fixing frame, the gear is arranged on a section of the transmission pipe located in the through hole, one end of the rack is hinged to the window frame, and the other end of the rack passes through the sliding groove and meshes with the gear, which has the advantage of being convenient for opening multiple windows at the same time.

[0004] The above-mentioned linked window opener still has certain shortcomings. The user drives the active shaft of the commutator to rotate by rotating the handle, so that the driven shaft of the commutator drives the transmission pipe to rotate, and the transmission pipe drives the multiple sets of window opening mechanisms equidistantly arranged on the transmission pipe to move. During movement, the gear arranged on the transmission pipe drives the rack to move to open the window.

A switch mechanism 5 for opening and closing the window 3 is provided on the front side of the wall 1. The switch mechanism 5 is used to facilitate opening multiple windows 3 at one time.

[0033] See also Figure 2-3 In order to facilitate opening multiple windows 3 at one time, the switch mechanism 5 in this embodiment includes a rotating component and a pushing component. The rotating component includes a shell 501 fixed to the front of the wall 1, a servo motor 502 fixed to the lower surface of the inner cavity of the shell 501, a first bevel gear 503 fixed to the output shaft of the servo motor 502, a first rotating rod 505 rotatably connected between the left and right sides of the inner cavity of the shell 501 through a bearing seat, a second bevel gear 504 fixed to the outer surface of the first rotating rod 505 and meshing with the first bevel gear 503, and a third bevel gear 506 fixed to the outer surface of the first rotating rod 505. The servo motor 502 drives the first bevel gear 503 to rotate, and drives the second bevel gear 504, the first rotating rod 505 and the two third bevel gears 506 to rotate together.

[0034] The pushing assembly includes a second rotating rod 508 rotatably connected to the inside of the housing 501 through a bearing, a fourth bevel gear 507 fixed to the lower surface of the second rotating rod 508 and meshing with the third bevel gear 506, and a push plate 509 fixed to the upper surface of the second rotating rod 508.

[0035] Two vertical blocks are fixed on the upper surface of the inner cavity of the shell 501 , and a round hole is opened on the left side of the vertical block. The first rotating rod 505 is rotatably connected to the inside of the round hole through a bearing, thereby increasing the stability of the first rotating rod 505 during rotation.

[0036] In addition, two rotating holes are opened on the upper surface of the housing 501 , and the second rotating rod 508 is rotatably connected to the inside of the rotating holes through bearings, thereby increasing the stability of the second rotating rod 508 during rotation.

[0037] In the switch mechanism 5 of this embodiment, the servo motor 502 drives the first bevel gear 503 to rotate, and drives the second bevel gear 504, the first rotating rod 505 and the two third bevel gears 506 to rotate together. The third bevel gear 506 drives the fourth bevel gear 507, the second rotating rod 508 and the push plate 509 to rotate together, pushing the window 3 to rotate, so as to facilitate opening multiple windows 3 for ventilation at one time.

[0038] See also Figure 4 In order to provide buffering for the window 3, the buffering mechanism 4 in this embodiment includes a first buffering component and a second buffering component. The first buffering component includes a fixed plate 401 fixed between the left and right sides of the inner cavity of the through hole 2, a box body 402 fixed to the middle part of the back side of the fixed plate 401, a sliding rod 407 fixed to the left and right sides of the box body 402, a fixed block 408 fixed to the left and right sides of the back side of the fixed plate 401, a telescopic rod 403 fixed to the front side of the inner cavity of the box body 402, a first spring 404 sleeved on the outer surface of the telescopic rod 403, a connecting rod 405 fixed to the back side of the telescopic rod 403, and a baffle 406 fixed to the back side of the connecting rod 405. The first spring 404 is made to perform a linear compression motion through the telescopic rod 403, and the connecting rod 405 and the baffle 406 are buffered by the first spring 404.

[0039] The second buffer assembly includes a moving block 410 slidably connected to the outer surface of the slide rod 407 , a second spring 411 sleeved on the outer surface of the slide rod 407 , and push blocks 409 fixed to the left and right sides of the front side of the baffle 406 .

[0040] Among them, the push block 409 is fitted with the moving block 410, and the push block 409 moves to push the moving block 410 to slide on the slide rod 407. A T-shaped block is fixed on the front of the moving block 410, and two T-shaped slots are opened on the back of the fixed plate 401. The T-shaped block is slidably connected to the inside of the T-shaped slot to increase the stability of the moving block 410 when moving.

[0041] In addition, the front side of the first spring 404 is fixed to the front side of the inner cavity of the box body 402, the back side of the first spring 404 is fixed to the front side of the connecting rod 405, the opposite sides of the two second springs 411 are respectively fixed to the left and right sides of the box body 402, and the opposite sides of the two second springs 411 are respectively fixed to the opposite sides of the two moving blocks 410, and a damping rubber block is fixed to the back side of the fixed block 408. Through the cooperation of the first spring 404 and the second spring 411, the baffle 406 is buffered and the window 3 is protected. The damping rubber block provides a damping effect to the first spring 404 and the second spring 411.

[0042] In the buffer mechanism 4 of this embodiment, when the push plate 509 is away from the window 3, the window 3 falls under the action of gravity and pushes the baffle 406 to move. The baffle 406 squeezes the first spring 404 through the connecting rod 405. The baffle 406 drives the push block 409 to move, pushes the moving block 410 to move and squeezes the second spring 411. The baffle 406 squeezes the damping rubber block. Through the movement of the baffle 406, the window 3 is buffered to prevent the glass in the window 3 from being damaged when the window 3 falls.

[0043] The working principle of the above embodiment is:

[0044] (1) When the window 3 needs to be pushed, the servo motor 502 is started. The servo motor 502 drives the first bevel gear 503 to rotate. The first bevel gear 503 rotates, which drives the second bevel gear 504 to rotate. The second bevel gear 504 drives the first rotating rod 505 to rotate together. The first rotating rod 505 drives the two third bevel gears 506 to rotate together. The third bevel gear 506 rotates, which drives the fourth bevel gear 507 to rotate together. When the fourth bevel gear 507 rotates, it drives the push plate 509 to rotate together through the second rotating rod 508. The push plate 509 rotates, which pushes the window 3 to rotate, so that multiple windows 3 can be opened for ventilation at one time.

[0045] (2) When the push plate 509 moves away from the window 3, the window 3 will be reset under the action of gravity. When the window 3 falls, it will push the baffle 406 to move. The baffle 406 will squeeze the telescopic rod 403 and the first spring 404 through the connecting rod 405. At the same time, the baffle 406 will drive the push block 409 to move. The push block 409 will push the moving block 410 to slide on the outer surface of the sliding rod 407 and squeeze the second spring 411. Finally, the baffle 406 will squeeze the damping rubber block. Through the movement of the baffle 406, the window 3 is buffered to prevent the glass in the window 3 from being damaged when the window 3 falls.
