Description

Technical Field

[0001] This application relates to the field of movable door and window equipment technology, and in particular to a lockable and adjustable drift window. Background Technology

[0002] Currently, the drifting sliding windows widely used in home decoration have a conventional locking structure that is only set on the side of the window frame. This can only achieve locking and limiting between the window sash and the window frame after the window sash is fully closed. The entire door and window system lacks an independent locking structure between the slide and the guide rail.

[0003] In actual home use, there are several shortcomings: First, when users open windows for ventilation, the window sash slides along the guide rail to any opening degree without fixed restraint. When it is windy outside, the window sash easily slides back and forth along the guide rail and hits the window frame, which not only generates continuous impact noise, but also causes deformation and wear of the window sash corners, guide rails, and sliding hardware over a long period of time, shortening the service life of the doors and windows. Second, existing doors and windows rely solely on a single-sided latch between the window sash and the window frame for limiting the position. The locking force point is singular. When encountering strong winds or external forces pushing the window sash, the latch is easily deformed and loosened due to concentrated force, resulting in insufficient anti-theft and anti-shaking performance. Third, the few doors and windows on the market with mid-way limiting functions mostly use external latches or magnetic positioning. External latches protrude from the window sash surface, affecting aesthetics, and the magnetic structure is significantly weakened by humidity and temperature differences, making it prone to failure in strong winds and unable to be used stably for a long time. Summary of the Invention

[0004] To improve the convenience of using a lockable adjustable drift window, this application provides a lockable adjustable drift window.

[0005] This application provides a lockable adjustable drift window, employing the following technical solution: A lockable adjustable drift window includes a window frame, a guide rail mounted on the window frame, a slide block slidably mounted on the guide rail, a movable plate rotatably mounted on the slide block, a window mounted on the movable plate, a locking assembly mounted on the slide block, the locking assembly including a first guide rod mounted on the slide block, a lifting block slidably mounted on the first guide rod, a first spring sleeved on the first guide rod, one end of the first spring connected to the lifting block and the other end connected to the first guide rod, a pressure plate mounted on the lifting block, the movable plate controlling the movement of the pressure plate, a second guide rod mounted on the lifting block, a slide plate slidably mounted on the second guide rod, a pressure strip for pressing the guide rail mounted on the slide plate, and a control assembly for controlling the movement of the slide plate mounted on the slide block.

[0006] By adopting the above technical solution, the slide can slide freely along the guide rail, and the movable plate rotates in conjunction with the window. When the window is rotated inward, the movable plate presses down on the pressure plate, causing the lifting block to move downward along the first guide rod. During the downward movement of the lifting block, the control component drives the sliding plate and pressure strip to press against the guide rail. The friction between the pressure strip and the guide rail restricts the sliding of the slide, enabling the window to be locked at any position within the sliding stroke. The first spring can automatically lift the lifting block after the window is opened outward and the movable plate is released from the pressure plate, releasing the pressure strip from clamping and limiting the guide rail, making the unlocking operation simple. This application adds a locking structure between the slide and the guide rail, which can simultaneously form a double lock between the window sash and the window frame, and between the slide and the guide rail when the window is closed, dispersing the locking force and greatly improving the overall locking stability of the window. No additional external limiting components are required, and the convenience of using the doors and windows and the reliability of locking are improved simultaneously.

[0007] In one specific implementation, the control component includes a push plate slidably mounted on the lifting block. A second spring is connected to the end of the push plate away from the guide rail. The end of the second spring away from the push plate is connected to the lifting block. A rotating rod is rotatably mounted on the lifting block. A swing plate is mounted on the rotating rod. The end of the swing plate near the push plate is movably connected to the push plate. The end of the swing plate near the slide plate is movably connected to the slide plate.

[0008] By adopting the above technical solution, when the lifting block moves downward, the guide rail squeezes the push plate to slide outward. The push plate drives the swing plate to rotate around the rotating rod. The rotation of the swing plate pulls the slide plate closer to one side of the guide rail, completing the clamping action of the pressure bar. The second spring continuously applies a reset pulling force to the push plate. After the lifting block is raised, the guide rail no longer squeezes the push plate, and the second spring can pull the push plate to reset, causing the swing plate to rotate in the opposite direction, and the slide plate simultaneously releases the guide rail. The entire transmission structure relies on mechanical linkage to achieve automatic switching between locking and unlocking. The transmission logic is coherent, eliminating the need for manual operation of locking components. The structure is integrated inside the lifting block, does not occupy external space, and is not prone to transmission failure during long-term repetitive use.

[0009] In one specific implementation, the swing plate has a first movable groove, the push plate is equipped with a first insert rod, the first insert rod is inserted into the first movable groove and slidably connected to the swing plate, the end of the swing plate near the slide plate has a second movable groove, the slide plate is equipped with a second insert rod, the second insert rod is inserted into the second movable groove and slidably connected to the swing plate.

[0010] By adopting the above technical solution, the swing plate makes an arc-shaped rotational motion, while the push plate and the slide plate can only move in a straight line. There is a displacement difference between their motion trajectories. The sliding cooperation between the movable groove and the insert rod can compensate for the stroke deviation and avoid jamming or jamming of the transmission structure. The contact area between the insert rod and the inner wall of the movable groove is large, resulting in lower friction loss. At the same time, it limits the rotation angle of the swing plate and prevents the swing plate from deflecting excessively and disengaging from the rod. This ensures that the feed amount of the slide plate is uniform each time it is locked, the clamping force of the pressure bar is stable, and the locking effect is uniform and reliable.

[0011] In one specific implementation, the end of the push plate near the guide rail is formed into an arc-shaped surface.

[0012] By adopting the above technical solution, the rail and the push plate have an arc-shaped tangential contact. During the downward movement of the lifting block, the guide rail smoothly squeezes the push plate, reducing metal friction resistance and making the window sliding feel lighter. The arc-shaped surface disperses the single-point compression stress, avoiding the long-term hard contact between the guide rail and the push plate, which may cause chipping or scratches. At the same time, it buffers the impact of the lifting block falling, reduces metal collision noise, and achieves silent locking.

[0013] In one specific implementation, the pressure plate has a beveled surface at one end near the movable plate.

[0014] By adopting the above technical solution, when the movable plate rotates inward, it gently presses down on the pressure plate along the inclined surface, smoothly converting the rotational force of the movable plate into the vertical downward movement force of the lifting block. The inclined surface buffers the impact of hard contact, and the locking mechanism can be triggered by slightly rotating the window, making the operation threshold low. The inclined surface is evenly stressed, and there will be no local stress bending or deformation of the pressure plate. The transmission force is stable over long-term use, and there will be no situation of weak downward pressure or incomplete locking.

[0015] In one specific implementation, the end of the guide rail away from the window frame is an arc surface, and the side of the slide block connected to the guide rail has an arc-shaped inner groove.

[0016] By adopting the above technical solution, the arc surface of the guide rail and the inner groove of the slide block are completely fitted together, increasing the contact area between the two, making the slide block more directional and preventing it from shifting or wobbling to the left or right; the arc-fitting structure distributes the overall weight of the window, preventing the guide rail from being deformed by local pressure, while reducing sliding friction resistance, making it easier and less effort to push and pull the window; in the locked state, the arc surface and the inner groove limit each other, eliminating the lateral gap of the slide block, further improving the stability of the window after it is locked.

[0017] In one specific implementation, the movable plate is equipped with a socket for inserting the window, the socket being frustoconical in shape.

[0018] By adopting the above technical solution, the frustum socket has a built-in guide cone surface, so there is no need for precise alignment when assembling windows. It can be directly plugged in and automatically aligned and positioned, simplifying the door and window assembly process and improving production assembly efficiency.

[0019] In one specific implementation, the pressure strip is made of rubber.

[0020] By adopting the above technical solutions, the coefficient of friction of rubber is much higher than that of metal. After pressing the guide rail, it can generate a strong static friction force, which effectively restricts the sliding of the slide block and prevents the window from moving and crashing on its own in windy weather. Rubber has an elastic buffering effect, and there is no metal impact noise when locking. At the same time, it isolates metal from direct contact and avoids scratches and oxidation of the guide rail and slide block. Rubber can adapt to the small processing tolerances of the profile, with a higher degree of fit, uniform clamping force, and less prone to one-sided clamping failure.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. This application uses a movable plate linkage locking component to enable the window to be locked at a fixed point after sliding to any ventilation opening. There is no need to hold the window sash to maintain the window gap. Unlocking only requires gently pushing the window outward. The locking and unlocking actions are integrated with the window sliding, which greatly improves the convenience of daily use and solves the pain points of traditional drift windows that can only be limited to the fully closed position and are easily affected by wind sliding and impact when the window is open.

[0022] 2. This application has a dual locking structure for the window sash and frame, and for the sliding block and guide rail. When the window is fully closed, the two locking points share the impact of external forces, which changes the defect of the traditional single lock where the force is concentrated. This effectively improves the window's resistance to wind and external shaking, significantly enhances the locking stability, and reduces the risk of lock deformation and loosening.

[0023] 3. The entire locking mechanism is a purely mechanical transmission structure, without magnetic or electronic components or other easily aging parts, and is not affected by humid, temperature difference or dusty environments; the plug and movable groove compensated transmission structure avoids jamming, and the rubber pressure strip buffers and reduces shock, reduces hardware wear, extends the overall service life of doors and windows, and reduces later maintenance costs.

[0024] 4. All locking and control components are integrated and installed inside the slide, with no external protruding locking parts, resulting in a smooth and beautiful appearance of the doors and windows; the cone socket simplifies window assembly, each hardware component is independently detachable, and a single worn part can be replaced individually, resulting in lower maintenance costs; the arc-shaped adaptable structure can be adapted to conventional drift window guides on the market, making it highly versatile for mass production.

One end of the first spring 2311 is fixedly connected to the lifting block 232, and the other end is fixedly connected to the first guide rod 231. A pressure plate 233 is fixedly installed on the top surface of the lifting block 232. The end of the pressure plate 233 near the movable plate 222 has a beveled surface 2331.

[0039] Reference Figure 6 , Figure 7 and Figure 8 A second guide rod 234 is fixedly installed on the lifting block 232. The second guide rod 234 is horizontally set. A slide plate 235 is slidably installed on the second guide rod 234. A pressure strip 236 is fixedly installed on the slide plate 235. The pressure strip 236 is made of rubber.

The control component 24 includes a push plate 241, which is slidably mounted on the lifting block 232. The end of the push plate 241 near the guide rail 11 has an arc-shaped surface 2411, and the end of the push plate 241 away from the guide rail 11 is fixedly connected to a second spring 242. The end of the second spring 242 away from the push plate 241 is fixedly connected to the lifting block 232. A rotating rod 243 is rotatably mounted on the lifting block 232, and a swing plate 244 is fixedly mounted on the rotating rod 243.

The second insert rod 246 is inserted into the second movable groove 2442 and slidably connected to the swing plate 244.

[0041] When the window 3 is sliding and needs to be locked, push the window 3 close to the window frame 1. The movable plate 222 on the slide block 2 will rotate. The end of the movable plate 222 that is equipped with the socket 223 will be close to the slide block 2. During the rotation, the movable plate 222 will contact the pressure plate 233. Through the action of the inclined surface 2331 on the pressure plate 233, the movable plate 222 will press down on the pressure plate 233, pushing the pressure plate 233 and the lifting block 232 to move closer to the guide rail 11. During the descent of the lifting block 232, the guide rail 11 will contact the push plate 241 and press the push plate 241 to move. The movement of the push plate 241 will drive the first insert rod 245 to move. The first insert rod 245 will push the swing plate 244 to rotate. The swing plate 244 will pull the second insert rod 246 to move. The second insert rod 246 will drive the slide plate 235 to move closer to the guide rail 11, so that when the window 3 is closed, the pressure strip 236 will be clamped on both sides of the guide rail 11, completing the locking of the window 3 and enabling the window 3 to stay stably in the position specified by the user.

[0042] The implementation principle of this application embodiment is as follows: This application utilizes the rotation of the movable plate 222 to drive the lifting block 232 to rise and fall vertically, and then drives the swing plate 244 to complete the movement reversal through the pressure of the guide rail 11 on the push plate 241. The vertical displacement of the lifting block 232 is converted into the horizontal clamping displacement of the sliding plate 235. Locking and unlocking can be completed simultaneously by simply pushing and pulling the window 3. The first spring 2311 and the second spring 242 respectively realize the automatic reset of the lifting block 232 and the push plate 241. The insertion rod and the movable groove compensate for the transmission stroke difference, ensuring smooth operation of the mechanism without jamming. The rubber pressure strip 236 provides sufficient friction to achieve fixed-point locking of the window at any position. At the same time, when the window is closed, it forms a double locking structure between the window sash and the window frame 1, and between the sliding seat 2 and the guide rail 11, dispersing the locking force and solving the problems of existing drift windows lacking guide rail 11 locking, inability to lock and stop at a fixed point when the window is open, and poor locking stability, thereby improving the convenience and durability of the doors and windows.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
