Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0029] In one embodiment, such as Figure 1 — Figure 5As shown, a protective sliding window with a lockable screen includes: a window frame 100, a window body 200, a screen 300, and a retractable assembly; the window body 200 is rotatably connected to the interior of the window frame 100; the screen 300 is also located inside the window frame 100; the retractable assembly includes a first support bar 401, which is slidably connected to one side of the window frame 100, and the side of the first support bar 401 near the window body 200 is connected to the screen 300; a hollow column 402 is provided inside the window frame 100, and a turntable 403 is rotatably connected to the upper and lower parts of the hollow column 402; a retractable rod 404 is fixedly connected between the two turntables 403, and the other end of the screen 300 is located on the retractable rod 404; the hollow column... A protrusion 405 is fixedly connected to the bottom end of the lower turntable 403 in 402. A torsion spring 406 is provided between the protrusion 405 and the bottom of the hollow column 402. A support component for supporting the screen 300 is provided on the window frame 100. A fixing component for fixing the window body 200 is also provided on the window frame 100. By pulling the first support bar 401, the screen 300 is moved. The movement of the screen 300 will drive the retractor 400 and the turntable 403 to rotate, thereby driving the protrusion 405 and the torsion spring 406. When it is necessary to retract, the tension on the first support bar 401 is released. Then, under the action of the torsion spring 406, the protrusion 405 and the turntable 403 reverse, thereby driving the retractor 404 to retract.
[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the support assembly includes a second support bar 501, which is disposed inside the window frame 100. A scissor lift 502 is provided between the second support bar 501 and the first support bar 401. One end of the scissor lift 502 near the first support bar 401 is rotatably connected to the first support bar 401, and the other end of the scissor lift 502 near the first support bar 401 is movably connected inside the first support bar 401. A sliding groove is provided on the second support bar 501, and a slider 503 is slidably connected in the sliding groove. The side of the scissor lift 502 near the second support bar 501 is rotatably connected to both the second support bar 501 and the slider 503. The window frame 100 is also provided with a locking assembly for locking the slider 503. The scissor lift 502 is supported by the second support bar 501, and the scissor lift 502 supports the first support bar 401.
[0031] In one embodiment, such as Figure 2 and Figure 5As shown, the fixing assembly includes two rotating rods 601, which are rotatably connected to the upper and lower parts of the window frame 100, respectively. A rotating gear 602 is provided on one end of each rotating rod 601, and a rack 603 meshes with the rotating gear 602. The rack 603 is slidably connected to the inside of the window frame 100 and the window body 200. A limiting assembly is provided on the rotating rod 601 to limit its movement. By rotating the rotating rod 601, it drives the rotating gear 602 to rotate, thereby driving the rack 603 to rise and fall, reaching the inside of the window body 200 and fixing the window body 200.
[0032] In one embodiment, such as Figure 1 and Figure 4 As shown, the locking assembly includes a limiting groove 701, which is formed on one side of the window frame 100. The window frame 100 also has several first limiting holes 702 at one end of the limiting groove 701. A threaded rod is provided on the side of the slider 503 near the limiting groove 701. A threaded sleeve 703 is threadedly connected to the outer surface of the threaded rod. As the first support bar 401 moves, it drives the scissor lift 502 to open and close, thereby causing the slider 503 to slide inside the second support bar 501. The threaded rod slides within the limiting groove 701. After the first support bar 401 moves to a suitable position, the threaded sleeve 703 is rotated to connect its interior to the threaded rod, subsequently reaching the first limiting hole 702, thus locking the slider 503 and preventing the first support bar 401 from moving.
[0033] In one embodiment, such as Figure 1 , Figure 2 and Figure 5 As shown, the limiting assembly includes a handle 801, which is fixedly connected to the outer surface of the rotating rod 601. A limiting rod 802 is slidably connected inside the end of the handle 801 away from the rotating rod 601. A plurality of second limiting holes are provided on the window frame 100. A limiting block is provided on the end of the limiting rod 802 near the second limiting hole. The limiting block is slidably connected inside the second limiting hole. A spring 803 is provided between the limiting block and the handle 801. By pulling the limiting rod 802, it causes the limiting block to squeeze the spring 803 and move away from the second limiting hole. By rotating the handle 801, it causes the rotating rod 601 to rotate. After rotating to a suitable position, the pulling force on the limiting rod 802 is released. Then, under the action of the spring 803, it causes the limiting block to reach the second limiting hole, thereby limiting the handle 801 and the rotating rod 601.
[0034] In one embodiment, such as Figure 5 As shown, a pull ring is provided on the end of the limiting rod 802 away from the second limiting hole, which facilitates pulling the limiting rod 802.
[0035] In one embodiment, such as Figure 4 As shown, the first limiting hole 702 and the threaded sleeve 703 are matched in shape and specification to prevent the threaded sleeve 703 from shaking.
[0036] In one embodiment, such as Figure 3 As shown, a slot is provided at one end of the hollow column 402 to facilitate the entry and exit of the screen window 300.
[0037] The above embodiment discloses a protective sliding window with a screen lock. When the window 200 needs to be opened, the limiting rod 802 can be pulled, causing it to drive the limiting block to compress the spring 803 and move it away from the second limiting hole. The handle 801 can then be rotated, causing the rotating rod 601 to rotate, which in turn drives the rotating gear 602 to rotate, thereby moving the rack 603 away from the window 200. After rotating to the appropriate position, the pulling force on the limiting rod 802 is released, and then, under the action of the spring 803, it moves the limiting block away from the second limiting hole. When the block reaches the second limiting hole, it limits the handle 801 and the rotating rod 601. At this time, the window 200 can be pushed away from the window frame 100. When it is necessary to pull the screen window 300, the first support bar 401 can be pulled to move the screen window 300. The movement of the screen window 300 will drive the retractor 400 and the turntable 403 to rotate, thereby driving the protrusion 405 and the torsion spring 406. As the first support bar 401 moves continuously, it will drive the scissor lift 502 to open and close, thereby driving... The slider 503 slides inside the second support bar 501, while the threaded rod slides within the limiting groove 701. After the first support bar 401 and the screen 300 move to the appropriate position, the threaded sleeve 703 is rotated to connect its interior to the threaded rod, and then reaches the first limiting hole 702, thereby locking the slider 503 and preventing the first support bar 401 from moving. When closing is required, the threaded sleeve 703 can be rotated again to move it away from the threaded rod, and then the locking of the first support bar 401 is released. The pulling force of 401, under the action of the torsion spring 406, causes the protrusion 405 and the turntable 403 to reverse, thereby driving the winding rod 404 to wind up and store the screen window 300. Then, the window body 200 is pulled closer to the window frame 100, and then the limiting rod 802 is pulled again, causing it to move the limiting block away from the second limiting hole, so that the handle can be rotated, thereby driving the rack 603 to reach the inside of the window body 200, thereby limiting it. The pulling force on the limiting rod 802 is released, so that it limits the rack 603.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
