Technical Field

[0001] The utility model relates to the technical field of aluminum-plastic doors and windows, and in particular to an aluminum-plastic door and window locking device with an anti-theft function. Background Art

[0002] Aluminum-plastic doors and windows are made of polyvinyl chloride resin as the main raw material, with a certain proportion of stabilizer, colorant, filler, UV absorber, etc., extruded into profiles, and then cut, welded or screwed into door aluminum-plastic window frames and sashes, equipped with sealing strips, wool strips, hardware, etc. At the same time, in order to enhance the rigidity of the profile, steel lining needs to be filled in the cavity of the profile that exceeds a certain length. The doors and windows made in this way are called aluminum-plastic windows.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the aluminum-plastic doors and windows in the prior art cannot fix the position of the window after opening, and are easily blown by the wind, which not only produces a loud impact sound, but also the long-term impact of the window will reduce the service life of the aluminum-plastic doors and windows. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an aluminum-plastic door and window locking device with an anti-theft function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an aluminum-plastic door and window locking device with anti-theft function, comprising an aluminum-plastic window frame and an aluminum-plastic window sash hinged on the aluminum-plastic window frame, the side wall of the aluminum-plastic window sash is fixed with an arc plate, the arc plate is penetrated by an arc-shaped tooth groove, the bottom wall of the aluminum-plastic window frame is rotatably connected with a rotating shaft, the upper end of the rotating shaft is fixed with a gear meshing with the arc-shaped tooth groove, a limiting component for limiting the rotating shaft is installed on the rotating shaft, and a locking component for locking the aluminum-plastic window sash is installed on the aluminum-plastic window frame.

[0006] By adopting the above technical solution, when the aluminum-plastic door and window needs to be opened, the user releases the locking effect of the locking component on the aluminum-plastic window sash, and then opens the aluminum-plastic window sash. The arc plate moves with the aluminum-plastic window sash, so that the gear rotates with the arc-shaped tooth groove on the arc plate. When it is opened to a suitable position, the user limits the rotating shaft through the limiting component, thereby limiting the rotation of the gear, thereby fixing the position of the arc plate and the aluminum-plastic window sash, reducing the probability of the aluminum-plastic window sash being blown by the wind after opening, and improving the stability of the aluminum-plastic window sash.

[0007] Furthermore, the limiting assembly includes an external thread arranged on the rotating shaft and a limiting nut sleeved on the rotating shaft and threadably connected to the external thread.

[0008] By adopting the above technical solution, when the aluminum-plastic window sash is opened to the appropriate position, the user needs to tighten the limit nut so that the bottom of the limit nut presses downward against the bottom wall of the aluminum-plastic window frame, thereby limiting the rotating shaft and reducing the probability of displacement of the aluminum-plastic window sash due to the rotation of the rotating shaft and gear.

[0012] By adopting the above technical solution, the locking block is inserted into the locking groove, thereby fixing the aluminum-plastic window sash on the aluminum-plastic window frame. When the aluminum-plastic window sash needs to be opened, the user pulls the cross bar and the locking block through the moving plate to make the locking block disengage from the locking groove and enter the installation groove, thereby opening the aluminum-plastic window sash and improving the anti-theft performance of the aluminum-plastic doors and windows.

[0013] Furthermore, a locking spring is arranged in the installation groove, one end of the locking spring is fixed to the inner wall of the installation groove, and the other end of the locking spring is fixed to the side wall of the locking block.

[0014] By adopting the above technical solution, the lock block remains plugged into the lock groove under the elastic force of the lock spring, reducing the probability of the lock block detaching from the lock groove under the action of external force, causing the aluminum-plastic window sash to open.

[0015] Furthermore, a side wall of the locking block away from the movable plate is provided with a yielding portion cooperating with the aluminum-plastic window sash.

[0017] Furthermore, a shock-absorbing pad is fixed to the inner wall of the locking groove.

[0018] By adopting the above technical solution, the shock-absorbing pad is made of rubber material, which is elastic. The locking block cooperates with the locking groove and presses against the shock-absorbing pad, thereby reducing the probability of shaking of the aluminum-plastic window sash.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. In the present application, when the aluminum-plastic door and window needs to be opened, the user releases the locking effect of the locking assembly on the aluminum-plastic window sash, and then opens the aluminum-plastic window sash.

When the door is opened to a suitable position, the user limits the rotation shaft through the limiting assembly, thereby limiting the rotation of the gear, thereby fixing the position of the arc plate and the aluminum-plastic window sash, reducing the probability of the aluminum-plastic window sash being blown by the wind after opening, and improving the stability of the aluminum-plastic window sash.

[0021] 2. In this application, when the aluminum-plastic window sash is opened to a suitable position, the user needs to tighten the limit nut so that the bottom of the limit nut presses down against the bottom wall of the aluminum-plastic window frame, thereby limiting the rotation shaft and reducing the probability of displacement of the aluminum-plastic window sash caused by the rotation of the rotation shaft and gear;

[0022] 3. In the present application, the locking block is inserted into the locking groove to fix the aluminum-plastic window sash on the aluminum-plastic window frame.

The arc plate 3 is a plate-like structure with an arc-shaped cross section, and the arc plate 3 is fixed on the side wall of the aluminum-plastic window sash 2, and an arc-shaped tooth groove 31 is penetrated through the arc plate 3. The rotating shaft 4 is a vertically arranged round rod-shaped structure, and the rotating shaft 4 is rotatably connected to the inner bottom wall of the aluminum-plastic window frame 1. The gear 5 is fixed on the upper end of the rotating shaft 4, and the gear 5 is meshed with the arc-shaped tooth groove 31, and the axis of the gear 5 coincides with the axis of the rotating shaft 4.

[0030] The limit assembly 6 is installed on the rotating shaft 4 and is used to limit the rotating shaft 4. The limit assembly 6 includes an external thread 61, a limit nut 62 and an annular rubber sheet 63. The external thread 61 is a threaded structure, and the external thread 61 is arranged on the outer wall of the rotating shaft 4. The limit nut 62 is sleeved on the rotating shaft 4, and the limit nut 62 is threadedly connected with the external thread 61, and the axis of the limit nut 62 coincides with the axis of the rotating shaft 4. The annular rubber sheet 63 is sleeved on the rotating shaft 4, and the annular rubber sheet 63 is arranged between the limit nut 62 and the inner bottom wall of the aluminum-plastic window frame 1.

[0031] The locking assembly 7 is installed on the aluminum-plastic window frame 1 and is used to lock the aluminum-plastic window sash 2. The locking assembly 7 includes a locking block 71, a cross bar 72 and a movable plate 73. The locking block 71 is arranged in the installation groove 11 and is slidably connected to the inner wall of the installation groove 11. The locking block 71 is plugged into the locking groove 21.
