All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0017] Please see Figures 1 to 4 This utility model provides a technical solution: a reset automatic closing aluminum alloy door and window, including a window frame 1, an installation frame 101 rotatably connected to the inner side wall of the window frame 1, a cavity is opened inside the window frame 1, an opening and closing component 2 is arranged inside the cavity, a positioning ring is installed on the inner side wall of the installation frame 101, the positioning ring can ensure that the glass plate 102 is in the correct installation position, the glass plate 102 is arranged on the front of the positioning ring, and the top and bottom of the front of the installation frame 101 are provided with installation grooves, and a fixing component 3 is arranged inside the installation grooves; The opening and closing assembly 2 includes a motor 201 fixedly connected to the inner wall of the cavity. The output end of the motor 201 is splinedly connected to a transmission rod. One end of the transmission rod is fixedly connected to a worm gear 202. A worm wheel 203 meshes with the surface of the worm gear 202. The worm wheel 203 and worm gear 202 transmission has a large transmission ratio and a self-locking function, which can prevent the mounting frame 101 from opening by external force after the door and window are closed, thus ensuring the stability of the closed state of the door and window. A connecting rod 204 is fixedly inserted through the top of the worm wheel 203, which drives the mounting frame 101 to rotate around the rotation connection point with the window frame 1, thereby realizing the opening or closing action of the door and window. The bottom of the connecting rod 204 is fixedly connected to the top of the mounting frame 101. The motor 201 is a NEMA17 stepper motor 201. The fixing component 3 includes a rotating groove formed on the inner side wall of the mounting groove. A rotating rod 301 is rotatably connected to the inner side wall of the rotating groove. A fixing plate 302 is fixedly connected to one end of the rotating rod 301. When it is necessary to fix the glass plate 102, the rotating rod 301 is rotated to make the fixing plate 302 rotate to a suitable position, so that the back of the fixing plate 302 contacts the front of the glass plate 102, thereby limiting the glass plate 102. The back of the fixing plate 302 contacts the front of the glass plate 102. Connecting blocks 303 are fixedly connected to both sides of the fixing plate 302, which cooperate with other components in the fixing component 3 to lock the fixing plate 302. The inner wall of the mounting slot is provided with a circular groove, and a locking block 304 is slidably connected to the inner wall of the circular groove. A spring 305 is connected between the back of the locking block 304 and the inner wall of the circular groove. A spherical groove adapted to the locking block 304 is provided on the back of the connecting block 303. The locking block 304 is engaged in the inside of the spherical groove. The locking block 304, the spring 305 and the spherical groove on the back of the connecting block 303 constitute a quick locking device for the glass plate 102, which securely fixes the glass plate 102 in the mounting frame 101. A detection strip 6 is fixedly connected to one side of the mounting frame 101. A placement groove adapted to the detection strip 6 is opened on the back of the window frame 1. A sensor 4 is installed on the inner wall of the placement groove. A controller 5 is installed on the front of the window frame 1. The sensor 4 is electrically connected to the controller 5. The detection strip 6 on one side of the mounting frame 101 rotates with the mounting frame 101. The sensor 4 senses the position change of the detection strip 6 in real time and transmits the signal to the controller 5, thereby controlling the operation of components such as the motor 201. The surface of the locking block 304 is fixedly connected to the limiting block 7. The inner side wall of the circular groove is provided with a limiting groove that matches the limiting block 7. The limiting block 7 is movably connected to the inner side wall of the limiting groove, which restricts the movement trajectory of the locking block 304 in the circular groove, prevents the locking block 304 from rotating circumferentially during sliding, and ensures that the locking block 304 can always be accurately locked into the spherical groove. The inner wall of the placement slot is fixedly connected with a shock-absorbing pad 8. The shock-absorbing pad 8 is made of rubber. The shock-absorbing pad 8 can buffer the impact force between the detection strip 6 and the sensor 4, and protect the sensor 4 from hard impact. A sealing gasket 9 is fixedly connected to the front of the positioning ring. The front of the sealing gasket 9 contacts the back of the glass plate 102. The sealing gasket 9 fits tightly against the back of the glass plate 102, filling the gap between the glass plate 102 and the positioning ring, significantly improving the sealing performance of the door and window.
[0018] In this invention, the working steps of the device are as follows: First step: When it is necessary to open or close the door or window, the motor 201 located in the cavity inside the window frame 1 starts. The output end of the motor 201 drives the worm gear 202, which is fixedly connected at one end, to rotate through the transmission rod. Based on the transmission principle of the worm wheel 203 and worm gear 202, the rotation of the worm gear 202 will drive the worm wheel 203 to rotate. Since the top of the worm wheel 203 is fixedly connected to the connecting rod 204, and the bottom of the connecting rod 204 is fixedly connected to the top of the mounting frame 101, the rotation of the worm wheel 203 can drive the connecting rod 204 to rotate, thereby realizing the rotation of the mounting frame 101 around the rotation connection point with the inner side wall of the window frame 1, and completing the opening or closing action of the door or window. Second step: During installation, first place the glass plate 102 inside the positioning ring, then rotate the rotating rod 301. The rotating rod 301 drives the fixing plate 302 to rotate around the rotating groove, so that the back of the fixing plate 302 contacts the front of the glass plate 102, which plays a preliminary limiting role for the glass plate 102. At this time, the connecting block 303 rotates with the fixing plate 302 to a suitable position. The locking block 304, which is slidably connected to the inner wall of the circular groove, is locked into the spherical groove opened on the back of the connecting block 303 under the elastic force of the spring 305, thereby locking the position of the fixing plate 302 and firmly fixing the glass plate 102 in the mounting frame 101.
