DETAILED DESCRIPTION
[0016] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0017] See also Figures 1 to 4 The present invention provides an automatic locking hook device for doors and windows, including a window frame 1, wherein the inner wall of the window frame 1 is provided with two slide grooves 8, an upper glass window 6 is fixedly installed on the inner wall of the window frame 1, a lower glass window 2 is slidably connected inside the two slide grooves 8, a locking mechanism 4 is arranged inside the window frame 1, a handle 3 is fixedly installed on the front of the lower glass window 2, and the handle 3 is made of plastic. The plastic handle 3 not only reduces the overall weight of the device and improves portability, but also the plastic handle 3 has good weather resistance and wear resistance, making the device more durable.
[0018] The locking mechanism 4 includes a connecting block 401, the upper surface of the connecting block 401 is fixedly connected to the bottom surface of the lower glass window 2, locking holes 403 are provided on both side surfaces of the connecting block 401, a locking chamber 402 is provided on the inner bottom wall of the window frame 1, and two fastening blocks 5 are fixedly installed on the outer surface of the handle 3, and the back side of each fastening block 5 is fixedly connected to the front side of the lower glass window 2. The fastening blocks 5 enhance the connection stability between the handle 3 and the lower glass window 2, prevent the handle 3 from loosening during use, and improve the safety and reliability of operation.
[0019] Two cavities 404 are provided on the inner wall of the locking bin 402, a telescopic column 406 is fixedly installed on the inner wall of each cavity 404, a telescopic spring 409 is fixedly installed on the inner side wall of each cavity 404, and a sealing strip 7 is fixedly installed on the outer surface of the window frame 1. The sealing strip 7 is made of silicone. The silicone sealing strip 7 provides good sealing performance, effectively preventing the influence of external factors such as wind and rain on the indoor environment, and at the same time improving the sound insulation and thermal insulation effects of doors and windows.
[0020] The outer surface of each telescopic spring 409 is fixedly connected to the outer surface of the telescopic column 406, and the side surfaces of the two telescopic springs 409 that are close to each other are fixedly installed with locking heads 407 that are compatible with the locking holes 403, and the side surfaces of the two locking heads 407 that are away from each other are fixedly installed with reinforcement blocks 9, and the bottom surface of each reinforcement block 9 is fixedly connected to the outer surface of the telescopic end of the telescopic column 406. The structural strength of the locking head 407 is increased by the reinforcement block 9, so that during the locking process, the locking head 407 can cooperate with the locking hole 403 more stably, thereby improving the locking effect and safety.
[0021] A connecting rod 408 is fixedly installed on the outer surface of each locking head 407, an operating rod 405 is fixedly installed on the end of each connecting rod 408 away from the locking head 407, and a reinforcement ring 10 is fixedly installed on the outer surface of each connecting rod 408. The back side of each reinforcement ring 10 is fixedly connected to the outer surface of the locking head 407. The reinforcement ring 10 further enhances the connection stability between the connecting rod 408 and the locking head 407, prevents the connecting rod 408 from bending or breaking during operation, and improves the durability and reliability of the entire locking mechanism 4.
[0022] Working principle: During use, when the doors and windows need to be closed, the user first holds the window through the plastic handle 3 on the front of the lower glass window 2. Since two fastening blocks 5 are fixed on the handle 3, these fastening blocks 5 are fixedly connected to the front of the lower glass window 2, providing a good grip and making the movement of the window smoother. As the lower glass window 2 slides along the slide groove 8 on the inner wall of the window frame 1, the window is gradually closed. When the lower glass window 2 is completely closed, the internal locking mechanism 4 begins to work. When the window is closed, the locking holes 403 on the two sides of the connecting block 401 cooperate with the telescopic column 406 and the telescopic spring 409 in the locking chamber 402 on the inner bottom wall of the window frame 1. The telescopic spring 409 pushes the locking head 407 to extend outward under the action of the spring force until it is adapted to the locking hole 403, thereby achieving automatic locking. At this time, the operating rod 405 is connected to the locking head 407 through the connecting rod 408. The user can manually unlock the door through the operating rod 405. When the window needs to be opened, the operating rod 405 is gently pulled, and the locking head 407 retracts under the action of the telescopic spring 409. The unlocking is completed, and the lower glass window 2 can slide open along the slide groove 8. This design not only facilitates the daily use of the user, but also ensures the safe sealing of the doors and windows.
