[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention automatically locks aluminum alloy doors and windows by having the outer bevel of the locking rod contact the door frame when the door or window is rotated into the door frame, and then engaging the lock hole inside the door frame via a compression spring. To open the door or window, a hand is inserted into the embedded handle, and the fingers grip the rotating plate. The rotating plate rotates upward by compressing the elastic plate, simultaneously moving the drive block upward and contacting the bevel of the drive rod. This pushes the drive rod to move, which in turn pushes the drive rod to move the gear. The gear then drives the locking rod inward and out of the lock hole, making it easy to open the door or window. The operation is simple and provides anti-theft protection.

[0016] Please see Figures 1-5 This utility model provides a technical solution: an automatic locking structure, comprising: an embedded handle 3 disposed on the inner side of one end of a door / window 1; a door frame 2 disposed on the outer side of the door / window 1; one end of the door / window 1 being rotatably connected to the door frame 2 via a hinge; a lock hole being provided on the inner end of the side of the door frame 2 away from the hinge; a rotating plate 7 being rotatably connected inside the embedded handle 3; lugs 6 being fixedly installed on both the upper and lower sides of the inner end of the embedded handle 3; one end of the rotating plate 7 being rotatably connected to the lugs 6 via a rotating shaft; and the rotating plate 7 and the embedded handle 3... The rotating plate 7 and the embedded handle 3 are elastically connected. An elastic sheet 8 is fixedly installed between the other end of the rotating plate 7 and the embedded handle 3. The elastic sheet 8 is U-shaped, with one end fixedly connected to the rotating plate 7 and the other end fixedly connected to the inner wall of the embedded handle 3. By inserting a hand into the embedded handle 3 and gripping the rotating plate 7 tightly with fingers, the rotating plate 7 rotates upward by squeezing the elastic sheet 8. A drive block 9 is fixedly installed on both the left and right sides of one end of the rotating plate 7. When the rotating plate 7 rotates, it will move the drive block 9 synchronously. A ramp is opened on the outer side of the upper end of the drive block 9.

[0017] The recessed handle 3 has sliding holes 5 at both its upper and lower ends. Two cavities 4 are symmetrically arranged on the upper and lower sides of the recessed handle 3. The sliding holes 5 and cavities 4 are connected. A drive rod 10 is slidably connected to both the upper and lower ends of the recessed handle 3. A bevel 21 is provided at both the left and right ends of the drive rod 10. A bevel 21 is provided at one end of the drive rod 13. A drive rod 13 and a locking rod 14 are slidably connected within the cavity 4. The outer ends of the 4 are all slidably sleeved with fixed sleeves 15. The outer wall of the fixed sleeves 15 is fixed in the cavity 4, guiding and limiting the drive rod 13 and the locking rod 14. The drive rod 13 and the locking rod 14 are meshed with gears 16. The outer walls of the drive rod 13 and the locking rod 14 are evenly fixed with several teeth. The gears 16 are rotatably connected in the cavity 4 through a rotating shaft, and the teeth and gears 16 mesh with each other. The drive rod 13 and the locking rod 14 move synchronously through the gears 16.

[0018] One end of the drive rod 10 passes through the sliding hole 5 and enters the cavity 4. A baffle 11 is fixedly installed on the outer wall of the drive rod 10. A spring 12 is sleeved on the outer end of the drive rod 10. One end of the spring 12 is fixed to the inner wall of the cavity 4, and the other end is fixed to the side wall of the baffle 11. When the spring 12 is in a balanced state, one end is in contact with the inclined surface 21 of one end of the drive rod 13. The other end of the drive rod 10 is in contact with the slope at the upper end of the drive block 9. One end of the locking rod 14 can pass through the door frame 2 and be inserted into the lock hole set in the door frame 2 to lock the door and window 1 in the door frame 2.

[0019] A baffle 17 is fixedly installed on the outer end of the locking rod 14. A fixing plate 18 is fixedly installed on one end of the fixing sleeve 15 located on the outer end of the locking rod 14. A spring 19 is sleeved on the outer end of the locking rod 14. One end of the spring 19 is fixedly connected to the baffle 17, and the other end is fixedly connected to the fixing plate 18. An inclined surface 20 is opened on the inner side of the outer end of the locking rod 14. When the spring 19 is in a balanced state, the outer end of the locking rod 14 is inserted into the lock hole opened on the door frame 2.

[0020] An aluminum alloy door and window includes the aforementioned automatic locking structure.

[0021] In actual use, when the door frame 1 is rotated into the door frame 2, the inclined surface 20 at the outer end of the locking rod 14 contacts the door frame 2, and the compression spring 19 enters the lock hole inside the door frame 2, locking the door and window 1, thus automatically locking the aluminum alloy door and window. When the door and window 1 needs to be opened, the hand is inserted into the embedded handle 3, and the fingers are tightly gripping the rotating plate 7. The rotating plate 7 rotates upward by compressing the elastic plate 8, and at the same time, it moves the drive block 9 upward and contacts the inclined surface 21 of the drive rod 10, thereby pushing the drive rod 10 to move. The drive rod 10 pushes the drive rod 13 to move, and the drive rod 13 drives the gear 16 to rotate. The gear drives the locking rod 14 to move inward and out of the lock hole, thus making it easy to open the door and window 1.
