[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.

[0022] As shown in Figures 1 to 6 , the window safety handle of the utility model comprises a base 1, a cover 2, a locking member 3, a first rotating member 4 and a second rotating member 5. The traditional handle is relatively simple, only comprising the base 1, the cover 2, the locking member 3 and a handle 6, the cover 2 is installed on the base 1, then the base 1 is fixed on the window, when the handle 6 is rotated, the handle 6 can drive the locking member 3 to rotate in the inside of the cover 2, so that the locking block 7 on the locking member 3 is turned out of the cover 2, so as to correspond with the locking groove on the window frame, and the window is locked.

[0023] The base 1 is fixed to the window, and the cover 2 is set on the base 1. The cover 2 has a mounting hole 8, and the locking element 3 is installed in the mounting hole 8. The upper end of the locking element 3 has a handle 6. The lower end of the handle 6 has a cross block 9. The locking element 3 has a cross groove 10 that mates with the cross block 9. The handle 6 has a fixing hole 11, and a bolt 12 is installed in the fixing hole 11, extending into the cross groove 10 to connect the handle 6 and the locking element 3. Through the cooperation of the cross block 9 and the cross groove 10, rotating the handle 6 causes the locking element 3 to rotate as well. The handle 6 and the locking element 3 are then connected and fixed by the bolt 12. A plug 13 can be installed in the fixing hole 11 for aesthetic purposes.

[0024] The locking component 3 consists of a column 14 and a disc 15. A locking block 7 is provided on the side wall of the disc 15, and a strip groove 16 for the locking block 7 to rotate is provided on the side wall of the cover 2.

[0025] The first rotating member 4 and the second rotating member 5 are mounted on the base 1. The first rotating member 4 is mounted on the base 1 via the first hinge shaft 17, and the second rotating member 5 is mounted on the base 1 via the second hinge shaft 18, so that the first rotating member 4 and the second rotating member 5 can rotate. The first rotating member 4 and the second rotating member 5 are in contact with each other. The second rotating member 5 is provided with a receiving opening 19. The lower end of the locking member 3 is provided with a locking rod 20 disposed in the receiving opening 19. The first rotating member 4 and the second rotating member 5 are connected by a tension spring 21.

[0026] The first rotating member 4 is provided with a first limiting arm 22, the first limiting arm 22 is provided with a protrusion 23, and a push rod 24 is provided on the protrusion 23. The cover body 2 is provided with an arc-shaped groove 25, and the push rod 24 is disposed in the arc-shaped groove 25. The second rotating member 5 is provided with a second limiting arm 221 and a third limiting arm 222, and a receiving opening 19 is formed between the second limiting arm 221 and the third limiting arm 222. The second limiting arm 221 contacts the first limiting arm 22 and is blocked by the first limiting arm 22.

[0027] The first rotating part 4 is provided with a positioning rod 26, and the second rotating part 5 is also provided with a positioning rod 26. The two ends of the tension spring 21 are respectively set on different positioning rods 26. Figure 6 The tension spring 21 is in a stretched state, the first rotating member 4 is positioned by the push rod 24, and the second rotating member 5 is limited by the first limiting arm 22.

[0028] like Figure 6As shown, pushing the push rod 24 within the arc-shaped groove 25 causes it to rotate the first rotating member 4 around the first hinge axis 17. This causes the first limiting arm 22 to slightly rotate the second rotating member 5. Since the width of the receiving opening 19 is greater than the diameter of the locking rod 20, the second rotating member 5 can rotate slightly, allowing the first limiting arm 22 to pass over the second limiting arm 221 and no longer obstruct its rotation. Then, the handle 6 can be turned clockwise, causing the locking member 3 to rotate, allowing the locking block 7 to rotate into the cover 2, while the locking rod 20 moves out of the receiving opening 19. At this point, the tension spring 21 pulls the second rotating member 5 to rotate, placing the second limiting arm 221 below the first limiting arm 22, and the receiving opening 19 no longer restricts the locking rod 20. Furthermore, when the locking rod 20 rotates the receiving port 19, it will push the third limiting arm 222 to avoid the locking rod 20, keeping the end of the third limiting arm 222 inside the B circle line, but not exceeding the C circle line. The locking rod 20 can push the third limiting arm 222 over when the locking member 3 rotates, and it can also push the third limiting arm 222 over when locking, and re-enter the receiving port 19.

[0029] When the handle needs to be closed again, turn the handle 6 counterclockwise. This pushes the third limiting arm 222 through the locking rod 20, causing the second rotating member 5 to rotate. The second limiting arm 221 is kept beyond the first limiting arm 22, thereby resetting the first rotating member 4 and the second rotating member 5. The tension spring 21 is kept in a stretched state again. The first limiting arm 22 blocks the position of the second limiting arm 221 again, so that turning the handle 6 cannot drive the second rotating member 5 to rotate through the locking rod 20.

[0030] When the locking rod 20 pushes the second rotating member 5 to reset and lock, since one end of the first rotating member 4 and the second rotating member 5 are connected by the tension spring 21, when the second rotating member 5 is pushed by the locking rod 20 to rotate in the direction of the tension spring 21, the second rotating member 5 will drive the tension spring 21 to pull it, and through the tension spring 21, it will pull the first rotating member 4 to rotate in the direction away from the tension spring 21, so that the first limiting arm 22 passes over the second limiting arm 221.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
