Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a double-track sliding aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows are widely used in houses nowadays. Aluminum alloy is durable and not easy to oxidize. Compared with untreated wooden doors and windows, the surface looks better. In order to ensure indoor ventilation, screens are usually installed at doors and windows. Screens play a role of dust prevention when doors and windows are opened. Since screens filter dust, they are usually set indoors to prevent dirt caused by rain falling on the screens. In actual use, locking mechanisms are usually installed on the inner end faces of doors and windows and fixedly connected to the window frames. When used for ventilation, the screens will block the locking mechanism, causing users to move the screens out of the doors and windows to unlock the doors and windows. After unlocking, the screens need to be reset, which is cumbersome. Utility Model Content

[0003] The purpose of the utility model is to provide a double-track sliding aluminum alloy door and window, which is used to overcome the above-mentioned defects in the prior art.

[0004] The cam is fixed on the left end surface of the rotating cover, and a cam is fixed on the rotating cover and located in the rotating cavity, and an upper anti-slip pad and a front anti-slip pad are fixed on the upper side wall of the rotating cavity and the front side wall of the rotating cavity, respectively. The circumferential surface of the cam can fit with the inner end surface of the upper anti-slip pad and the front anti-slip pad, and the rear side of the rotating cavity is connected to the sliding cavity, and an insert block is slidably connected in the sliding cavity, and a tension spring is connected between the sliding cavity and the insert block, and the insert block extends backward and is inserted into the rear window, and glass and waterproof glue are both provided in the rear window and the front window, and the screen window surface is installed indoors.

[0005] The beneficial effects of the utility model are:

[0006] By controlling the rotation of the rotating cover, the fixed connection between the rear window and the front window is controlled, thereby realizing left and right pushing of the rear window and the front window, and further realizing left and right movement control of the rear window and the front window without moving the screen window.

[0007] The fit between the front anti-skid pad and the cam increases the force required for the cam to rotate, thereby improving the stability of the cam. The fixed connection between the rear window and the front window is achieved by adding an insert into the rear window, which is convenient, fast and simple in structure.

[0016] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time: Example 1:

[0018] Reference Figures 1-6According to an embodiment of the present invention, a double-track sliding aluminum alloy door and window comprises a rear window 10 and a front window 11 distributed front and back. A screen 12 is provided at the front end of the front window 11. A rotating cavity 13 is provided at the left end of the front window 11. A rotating cover 14 is rotatably connected in the rotating cavity 13. A convex plate 15 is fixed on the left end surface of the rotating cover 14. The convex plate 15 extends to the left and passes through the rotating cavity 13. A cam 16 is fixed on the rotating cover 14 and located in the rotating cavity 13. The upper side wall of the rotating cavity 13 is connected to the rotating cavity 13. The front side walls of 13 are respectively fixed with an upper anti-slip pad 21 and a front anti-slip pad 22. The circumferential surface of the cam 16 can fit with the inner end surfaces of the upper anti-slip pad 21 and the front anti-slip pad 22. The rear side of the rotating cavity 13 is connected to a sliding cavity 17. An insert block 23 is slidably connected in the sliding cavity 17. A tension spring 24 is connected between the sliding cavity 17 and the insert block 23. The insert block 23 extends backward and is inserted into the rear window 10. Glass 19 and waterproof glue 20 are provided in both the rear window 10 and the front window 11. The screen 12 is installed indoors.

[0019] When closed, the rear window 10 and the front window 11 are Figure 1 As shown, the left and right sides are separately arranged, the left end of the rear window 10 and the right end of the front window 11 are respectively attached to the wall or frame surface at the left and right ends, and the rear window 10 and the front window 11 are slidably arranged on the frame;

[0020] During ventilation, the user controls the rotation of the rotating cover 14 at the front window 11. Specifically, the user holds the convex plate 15 protruding from the left end surface of the rotating cover 14 and pushes the convex plate 15 to rotate the rotating cover 14 in the rotating cavity 13. Figure 6 As shown, in the fixed state of the rear window 10 and the front window 11, the cam 16 extends forward and backward, the front end of the cam 16 is in contact with the front anti-skid pad 22, and the front anti-skid pad 22 prevents the cam 16 from sliding, and the rear end of the cam 16 is in contact with the insert block 23, and the insert block 23 is supported by the cam 16, thereby keeping the insert block 23 inserted into the rear window 10. During the rotation of the rotating cover 14, the cam 16 rotates circumferentially through the fixed connection, and then the cam 16 is transformed from the front and rear extension state to the up and down extension state, and the cam 16 is in contact with the upper end. The anti-slip pad 21 abuts, and the insert block 23 loses the support of the cam 16 and slides into the sliding cavity 17 under the spring tension of the tension spring 24. The insert block 23 loses the abutment with the rear window 10, thereby pulling the front window 11 to the left, so that the rear window 10 and the front window 11 correspond to each other front and back. The screen 12 is set at the right end of the rear window 10 and the front window 11 for ventilation and to intercept dust in the air. The rear window 10 can also be pulled to the right, so that the rear window 10, the front window 11 and the screen 12 correspond to each other front and back for ventilation.

[0021] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention. All such modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims appended hereto.
