Description

Technical Field

[0001] This utility model relates to the field of sliding door and window technology, specifically a micro-sliding sliding door and window anti-misoperation device. Background Technology

[0002] Currently, there is a problem when using micro-sliding doors and windows. The door and window sashes need to be opened in the correct order. Specifically, the active sash must be opened first, and then the passive sash can be opened. However, the active and passive sashes look the same, so it is easy to mistakenly open the passive sash first. If the passive sash is opened directly without opening the active sash, it may cause the passive sash to fall off, which could lead to a serious accident.

[0003] According to a public announcement of a concealed anti-misoperation switch device for micro-sliding sliding doors and windows (Announcement No.: CN221169086U), the above application includes a frame, in which an active fan and a passive fan are rotatably connected. The active fan and the passive fan are respectively located on the inner walls of the two sides of the frame. The frame has a device cavity and a slide groove, which communicate with the slide groove. A limit groove is opened at the upper end of the passive fan, and a second piston is slidably connected in the slide groove.

[0004] However, in actual use, the handles of the aforementioned switching devices are not marked for the active and passive fans. The active and passive fans look the same and have no markings on the handles. Without understanding the internal structure or operating logic, users cannot intuitively identify which is the active fan. This can lead to the operator mistakenly pulling the passive fan first. Since the passive fan is still in a limited position at this time, forcibly pulling it will cause abnormal stress on the limit rod and limit groove structure, resulting in damage or deformation of the mechanism. In extreme cases, if the limit structure or connecting parts are loose, the passive fan may derail, fall, or detach, causing a safety accident. In view of this, we propose a micro-sliding sliding door and window anti-misoperation switching device. Utility Model Content

[0005] The purpose of this invention is to provide a micro-sliding sliding door and window anti-misoperation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a micro-sliding sliding door and window anti-misoperation opening and closing device, including a window frame, an active sash hinged to the inner wall of the window frame, a driven sash hinged to the inner wall of the window frame, a locking component inside the window frame for distinguishing between the active and driven sashes, the locking component including a first synchronous wheel fixedly connected to the top end face of the active sash, a rotating rod rotatably connected to the inner wall of the driven sash, a handle fixedly connected to the side wall of the rotating rod, a second synchronous wheel fixedly connected to the top end of the rotating rod, and a synchronous belt sleeved on the inner wall of the window frame.

[0007] Preferably, the first synchronous pulley is connected to the synchronous belt drive, and the second synchronous pulley is connected to the synchronous belt drive, so that the movement of the first synchronous pulley can drive the synchronous belt to move, and further cause the second synchronous pulley to rotate.

[0008] Preferably, the driven fan has a storage groove on its side wall, which is movably connected to the handle. The storage groove is used to store the handle, so that the user cannot directly pull the driven fan by the handle.

[0009] Preferably, the locking assembly further includes an elastic element disposed on the inner wall of the window frame. The elastic element includes a sleeve fixedly connected to the inner wall of the window frame. The sleeve is sleeved with an abutment rod. A spring is disposed on the inner wall of the sleeve. One end of the spring abuts against the inner wall of the sleeve, and the other end of the spring abuts against the abutment rod. The abutment rod abuts against the timing belt. The elastic element presses against the timing belt, so that the timing belt is always kept taut.

[0010] Preferably, the inner top surface of the window frame is provided with an arc-shaped groove, which is movably connected to a first synchronous wheel and a second synchronous wheel.

[0011] Preferably, the arc-shaped groove is provided with a shielding component to cover the opening of the arc-shaped groove. The shielding component includes a rotating shaft rotatably connected inside the window frame. A shielding plate is fixedly connected to the side wall of the rotating shaft. A coil spring is sleeved on the side wall of the rotating shaft. Synchronous wheel one and synchronous wheel two can push the shielding plate in and out of the arc-shaped groove.

[0012] Preferably, one end of the coil spring is fixedly connected to the side wall of the rotating shaft, and the other end of the coil spring is fixedly connected to the inner wall of the window frame. When the synchronous wheel one and synchronous wheel two push the baffle plate to rotate, the coil spring accumulates elastic potential energy. Then, the coil spring releases the elastic potential energy to reset the baffle plate and block the opening of the arc groove.

[0013] Compared with the prior art, this utility model provides a micro-sliding sliding door and window anti-misoperation device, which has the following beneficial effects:

[0014] 1. This micro-sliding sliding door and window anti-misoperation switch device physically limits the opening sequence through a locking component. Without opening the active sash, the handle on the driven sash cannot be pulled directly, avoiding the risk of the user accidentally opening the driven sash first, which could damage the limiting structure, cause the driven sash to derail or fall, and improve the structural safety and anti-fall performance of the door and window system during use. The spring applies continuous elastic force to the synchronous belt, keeping the synchronous belt always taut and preventing transmission delay or slippage due to slack. This ensures that the synchronous belt will not affect the transmission effect due to slack during long-term operation.

[0015] 2. This micro-sliding sliding door and window anti-misoperation device, through the set baffle, blocks the arc-shaped groove opening when the door and window are closed or stationary. This not only improves the overall appearance of the window frame, but also prevents users from accidentally touching the moving parts inside the arc-shaped groove, avoiding accidental risks such as pinching and scratching, thereby improving the safety and appearance integrity of the entire window system.

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a micro-sliding sliding door and window anti-misoperation opening and closing device, including a window frame 1, an active sash 2 hinged to the inner wall of the window frame 1, a driven sash 3 hinged to the inner wall of the window frame 1, a locking component 4 for distinguishing between the active sash 2 and the driven sash 3 is provided inside the window frame 1, the locking component 4 includes a first synchronous wheel 401 fixedly connected to the top end face of the active sash 2, a rotating rod 402 rotatably connected to the inner wall of the driven sash 3, a handle 403 fixedly connected to the side wall of the rotating rod 402, a second synchronous wheel 404 fixedly connected to the top end of the rotating rod 402, and a synchronous belt 406 sleeved on the inner wall of the window frame 1.

[0023] In one embodiment of this utility model, synchronous pulley 401 is connected to synchronous belt 406, and synchronous pulley 404 is also connected to synchronous belt 406, so that the movement of synchronous pulley 401 can drive synchronous belt 406 to move, and further cause synchronous pulley 404 to rotate. An arc-shaped groove is provided on the inner top surface of window frame 1, which is movably connected to synchronous pulley 401 and synchronous pulley 404. A storage groove 405 is provided on the side wall of driven fan 3, which is movably connected to handle 403. The storage groove 405 is used to store handle 403, so that the user cannot directly pull driven fan 3 through handle 403.

[0024] The locking assembly 4 also includes an elastic element 407 disposed on the inner wall of the window frame 1. The elastic element 407 includes a sleeve fixedly connected to the inner wall of the window frame 1. The sleeve is sleeved with an abutment rod. A spring is disposed on the inner wall of the sleeve. One end of the spring abuts against the inner wall of the sleeve, and the other end of the spring abuts against the abutment rod. The abutment rod abuts against the timing belt 406. The elastic element 407 presses against the timing belt 406, so that the timing belt 406 is always kept taut.

[0025] When a user prepares to open a door or window, they first pull the active fan 2, causing the first synchronous pulley 401 to drive the synchronous belt 406 to rotate, which in turn drives the second synchronous pulley 404 to rotate synchronously. This causes the lever 402 to rotate, allowing the handle 403 to rotate out of the storage slot 405. The user can then hold the handle 403 to continue opening the driven fan 3. Conversely, when the active fan 2 is closed, the first synchronous pulley 401 does not drive the synchronous belt 406, and the second synchronous pulley 404 of the driven fan 3 will not rotate. At this time, the handle 403 is stored in the storage slot 405, preventing the user from directly holding or pulling the driven fan 3, thus preventing accidental operation.

[0026] During the closing process of doors and windows, the driven sash 3 is closed first. Since the user holds the handle 403, it drives the rotating rod 402 and the synchronous pulley 404 to rotate. At this time, the synchronous pulley 404 only drives the synchronous belt 406 to rotate idly. Subsequently, the user closes the active sash 2. The synchronous pulley 401 moves in the opposite direction with the active sash 2, driving the synchronous belt 406 to move in the opposite direction, which in turn drives the synchronous pulley 404 to rotate in the opposite direction. This causes the rotating rod 402 to drive the handle 403 to rotate back into the storage groove 405, realizing the automatic hiding of the handle 403. The mechanical linkage physically limits the opening sequence, avoiding the risk of the user accidentally opening the driven sash 3 first, which could damage the limiting structure, cause the driven sash 3 to derail or fall, and improve the structural safety and anti-fall performance of the door and window system during use.

[0027] The spring applies a continuous elastic force to the synchronous belt 406, keeping the synchronous belt 406 always taut. This prevents the synchronous belt 406 from experiencing transmission delays or slippage due to slack, ensuring that the synchronous belt 406 will not affect the transmission effect due to slack during long-term operation, and further ensuring the reliability and stability of synchronous transmission.

[0028] In addition, a shielding component 5 is provided inside the arc-shaped groove to cover the opening of the arc-shaped groove. The shielding component 5 includes a rotating shaft 501 rotatably connected inside the window frame 1. A shielding plate 502 is fixedly connected to the side wall of the rotating shaft 501. A coil spring 503 is sleeved on the side wall of the rotating shaft 501. The first synchronous wheel 401 and the second synchronous wheel 404 can push the shielding plate 502 in and out of the arc-shaped groove. One end of the coil spring 503 is fixedly connected to the side wall of the rotating shaft 501, and the other end of the coil spring 503 is fixedly connected to the inner wall of the window frame 1. When the first synchronous wheel 401 and the second synchronous wheel 404 push the shielding plate 502 to rotate, the coil spring 503 accumulates elastic potential energy. Then, the coil spring 503 releases the elastic potential energy to reset the shielding plate 502, thus shielding the opening of the arc-shaped groove.

[0029] When synchronous wheel 1 401 or synchronous wheel 2 404 moves, its edge will push the blocking plate 502 to deflect, causing the blocking plate 502 to temporarily leave the opening of the arc groove so that the synchronous wheel can pass freely. During this process, the coil spring 503 is twisted and deformed, storing elastic potential energy. After synchronous wheel 1 401 and synchronous wheel 2 404 have rotated through, the coil spring 503 releases the elastic potential energy, driving the rotating shaft 501 to rotate in the opposite direction, so that the blocking plate 502 automatically returns to its original position and blocks the opening of the arc groove again, realizing automatic reset. The blocking plate 502 blocks the opening of the arc groove when the door and window are closed or stationary, which not only improves the overall appearance of the inside of the window frame 1, but also prevents users from accidentally touching the moving parts inside the arc groove, avoiding accidental risks such as pinching and scratching, thereby improving the safety and appearance integrity of the entire window system.

[0030] In this invention, when the user pulls the active fan 2, the first synchronous pulley 401 drives the synchronous belt 406 to rotate, which in turn drives the second synchronous pulley 404 and the rotating rod 402 to rotate, causing the handle 403 to rotate out of the storage slot 405. The user can then continue to turn on the driven fan 3. When the active fan 2 is closed, the handle 403 is re-stored in the storage slot 405 to prevent accidental operation. During the closing process, when the driven fan 3 is closed first and then the active fan 2 is closed, the first synchronous pulley 401 moves in the opposite direction, causing the synchronous belt 406 to rotate in the opposite direction, so that the handle 403 is automatically stored. The spring in the elastic element 407 applies continuous tension to the synchronous belt 406 to maintain the stability and reliability of the synchronous transmission, prevent slippage and jamming caused by slack, and ensure structural stability.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
