[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1-5 As shown, this embodiment provides a secure anti-theft door and window, including a window mounting bracket 1. A glass window 2 is disposed inside the window mounting bracket 1. Screen window perforations 101 are provided on both the left and right sides of the window mounting bracket 1. A screen window 5 is disposed inside the screen window perforation 101. The outer side of the screen window 5 is made of a metal frame. A limiting baffle 502 is installed at the outer end of the screen window 5. The outer diameter of the limiting baffle 502 is greater than the inner diameter of the screen window perforation 101. The screen window 5 is located on the inner side of the end furthest from the limiting baffle 502. A locking hole 501 is provided. A winding roller 6 is installed on the side of the window mounting bracket 1 away from the glass window 2. A window closing rope 601 is connected between the outer side of the winding roller 6 and the glass window 2. A fixed pulley 4 is installed on the side surface of the window mounting bracket 1 directly above the winding roller 6. A window opening rope 3 is connected between the outer side of the fixed pulley 4 and the glass window 2. Both the window opening rope 3 and the window closing rope 601 are fixedly connected to the glass window 2. A through hole is provided inside the window mounting bracket 1 corresponding to the outer side of the window opening rope 3 and the window closing rope 601.

[0023] like Figure 2-3 As shown, in this embodiment, a swing arm groove 102 is provided on the inner side wall of the window mounting bracket 1. A switch swing arm 201 is installed inside the swing arm groove 102 on the side surface of the glass window 2. The switch swing arm 201 is movably connected to both the glass window 2 and the window mounting bracket 1. A sliding rod 103 is installed on the upper end of the glass window 2 inside the swing arm groove 102. A rotating shaft is installed between the winding roller 6 and the window mounting bracket 1. A ratchet 602 is installed on the outer side of the rotating shaft. A limiting pawl 603 is installed on one side of the ratchet 602 on the side surface of the window mounting bracket 1. The limiting pawl 603 meshes with the ratchet 602. The winding roller 6 is rotatably connected to the window mounting bracket 1 through the rotating shaft.

[0024] The working principle of this utility model is as follows: During use, after inserting two screen windows 5 through the screen window through holes 101 on both sides of the window mounting bracket 1, a lock is placed inside the locking holes 501 on the two screen windows 5 to lock them together. The limiting baffles 502 at the ends of the two screen windows 5 can limit the movement outside the screen window through holes 101, thus the entire screen window 5 can also function as a burglarproof window. When it is necessary to open the window, after the limiting pawl 603 is disengaged and the ratchet 602 is limited, the window opening rope 3 is pulled. Under the reversing action of the fixed pulley 4, the lower end of the glass window 2 is pulled up. The sliding rod 103 on the upper outer side of the glass window 2 slides downward inside the swing arm slide groove 102. The swing arm slide groove 102 connecting the window mounting bracket 1 and the glass window 2 swings, rotating the entire glass window 2 inside the window mounting bracket 1 to open it. When it is necessary to close the window, the torque applied to the winding roller 6 is used to wind up the window closing rope 601, thus closing the glass window 2. At the same time, the unidirectional limiting action of the limiting pawl 603 and ratchet 602 can achieve the purpose of locking from the inside, increasing safety. Moreover, the entire device can control the opening and closing of the glass window 2 without opening the screen window 5, which can reduce the entry of mosquitoes into the room.
