[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] like Figure 1-Figure 7As shown, the utility model provides a window protection device for preventing accidental falling from a building, comprising: a window body, which is composed of two side frames 3 and a bottom frame 4; a bottom net 6, which is connected between the bottom frame 4 and the frame 1; a side net 5, which is a triangular structure, with the top fixed on the frame 1, and the two sides and the bottom of the side net 5 are connected between the side frame 3 and the frame 1; a plurality of first winding members, which are located at the bottom of the frame 1, and the first winding members are fixedly connected to the bottom net 6; a second winding member, which is located between the side frame 3 and the frame 1, and the side net 5 is connected to the second winding member.
[0027] The tops of the side frames 3 on both sides of the window body are rotatably connected to the frame 1 through the rotating rod 2, and the two ends of the rotating rod 2 are rotatably connected to the frame 1. When the window is opened, the bottom frame 4 is rotated away from the frame 1, so that the window is in an open state. After being in the open state, a top rod is used to support between the bottom frame 4 and the frame 1 (not shown in the figure) to keep the window in the open state.
[0028] A first receiving groove 7 is provided at the bottom of the frame 1 , and the first receiving groove 7 is used to receive the bottom net 6 . When the window is in a closed state, the bottom net 6 shrinks into the first receiving groove 7 .
[0029] like Figure 6 and Figure 7 As shown, a plurality of fourth receiving grooves 10 are provided at the bottom of the frame 1, and the fourth receiving grooves 10 are located at the rear side of the first receiving groove 7. A first winding member is provided in the fourth receiving groove 10, and the first winding member is a vortex spring 11. The vortex spring 11 includes a fixed end 1101 and a hook end 1102. A fixed rod 12 is fixed to the fixed end 1101. Both ends of the fixed rod 12 are respectively fixed to both sides of the fourth receiving groove 10, and a bottom net 6 is fixed to the hook end 1102; the other end of the bottom net 6 is fixedly connected to the bottom frame 4. When the window is opened, the bottom frame 4 moves away from the frame 1. The bottom net 6 moves in the direction of the hook end 1102 to open, and the other end of the bottom net 6 pulls the hook end 1102 to move away from the fixing rod 12, so that the vortex spring 11 contracts. When the window is closed, the bottom frame 4 moves toward the frame 1, and the bottom net 6 moves toward the frame 1 under the action of the vortex spring 11, and finally contracts into the first receiving groove 7; when the bottom net 6 is opened, the two ends of the bottom net 6 are respectively fixed on the hook end 1102 and the bottom frame 4, so as to block the gap after the window is opened, and effectively prevent people or objects from falling through the gap.
[0030] The top of the side net 5 is fixed to the top of both sides of the frame 1 through a fixing shaft 17, and the bottom of the side net 5 is connected between the frame 1 and the side frame 3 through a second winding member.
[0031] Second receiving grooves 8 are provided on both sides of the frame 1 , and third receiving grooves 9 are provided on the side frame 3 . The second receiving grooves 8 correspond to the third receiving grooves 9 , and a second winding member is provided between the second receiving grooves 8 and the third receiving grooves 9 .
[0032] like Figure 3-Figure 5 As shown, the second winding member includes a first rotating wheel 13, a second rotating wheel 14, a connecting rope 15 and a spring 16. The first rotating wheel 13 is rotatably located in the second receiving groove 8, and the rotating shaft of the first rotating wheel 13 is rotatably connected to the two sides of the second receiving groove 8. The second rotating wheel 14 is located in the third receiving groove 9, and the rotating shaft of the second rotating wheel 14 is rotatably connected to the two sides of the third receiving groove 9. The connecting rope 15 is wound between the first rotating wheel 13 and the second rotating wheel 14, and the two ends of the connecting rope 15 are respectively fixed to the two ends of the bottom of the side net 5. The spring 16 is arranged between the first rotating wheel 13 and the second rotating wheel 14, and the two ends of the spring 16 are respectively fixed to the two ends of the bottom of the side net 5. The two ends of the spring 16 are fixedly connected to the two ends of the connecting rope 15. The connecting rope 15 is wound around the bottom of the first rotating wheel 13 and the second rotating wheel 14, and the spring 16 is arranged between the first rotating wheel 13 and the second rotating wheel 14. The spring 16 is located at the top of the first rotating wheel 13 and the second rotating wheel 14. It is worth mentioning that the top of the side net 5 is fixed to the top of the frame 1, and the two ends of the bottom of the side net 5 are respectively connected between the first rotating wheel 13 and the second rotating wheel 14, so that when the window is in an open state, the bottom of the side net 5 is in a triangular open state. At this time, the connecting rope 15 is in a stretched state between the first rotating wheel 13 and the second rotating wheel 14, and the spring 16 is also in a stretched state. The side net 5 is opened to block the side gap between the window and the frame 1, thereby improving the safety performance when the window is opened. When the window is closed, the spring 16 contracts, driving the connecting rope 15 to bypass the second rotating wheel 14, so that the side of the bottom of the side net 5 close to the side frame 3 contracts toward the second storage groove 8, and finally the side net 5 contracts into the second storage groove 8.
[0033] In this embodiment, when the window is opened, the bottom net 6 and the side net 5 are opened, the bottom net 6 pulls the hook end 1102 to move away from the frame 1, the vortex spring 11 contracts, and the bottom side of the side net 5 pulls the spring 16 to move away from the frame 1, so that the spring 16 is in a stretched state, and the connecting rope 15 is located at the bottom of the first rotating wheel 13 and the second rotating wheel 14. The bottom net 6 and the side net 5 are opened to block the bottom and sides of the window to prevent people or objects from falling from a high building; when the window is closed, the vortex spring 11 contracts, the hook end 1102 drives the bottom net 6 to retract into the first receiving groove 7, and the contraction of the spring 16 drives the side net 5 to retract into the second receiving groove 8, and the connecting rope 15 is wound around the top of the first rotating wheel 13 and the second rotating wheel 14 as the spring 16 contracts.
[0034] When the window of the device is opened, the bottom net 6 and the side net 5 are both in the open state, and the bottom seam and the side seam of the window are covered after the window is opened. While achieving ventilation and light transmission, it can prevent children from accidentally falling from the window and avoid falling objects from high altitude. It can also dispel the intention of people suffering from depression to jump from the window, thereby improving safety performance.
