[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1, please refer to Figures 1 to 6 This embodiment provides an intelligent building anti-theft system, including a window frame 1. Several sealing plates 2 are rotatably installed at equal intervals on the inner wall of the window frame 1. A rotating assembly for driving the sealing plates 2 to rotate is fixed at the upper end of the window frame 1. The rotating assembly includes a first rack 3 slidably connected to the outer wall of the upper end of the window frame 1 via a linear slide rail. A rotating shaft 4 is fixed at the middle of both ends of the sealing plates 2. The rotating shaft 4 is rotatably connected to the inner wall of the window frame 1. The upper end of the rotating shaft 4 extends to the outer side of the window frame 1 and is fixed with a first gear 5. Multiple second gears 12 are meshed with the first rack 3. A first electric push rod 6 is fixed to the outer wall of the upper end of the window frame 1. The protruding end of the first electric push rod 6 is fixed to the outer wall of the first rack 3.

[0027] In the existing technology, infrared sensors and iris recognition sensors are installed on the outside of the window frame 1 to identify people outside the window frame 1. When a person is detected, the sealing plate 2 is controlled to close, thus achieving the effect of intelligent anti-theft.

[0028] When the sealing plate 2 is driven to rotate, the first electric push rod 6 is extended or retracted, which drives the first rack 3 to slide. The first rack 3 simultaneously drives multiple first gears 5 to rotate, which can achieve the effect of driving the sealing plate 2 to flip, thereby achieving the effect of opening and closing the window frame 1.

[0029] The upper and lower ends of the window frame 1 are both provided with opposing sliding grooves 7. When several sealing plates 2 are in a closed window frame 1 position, such as Figure 4 and Figure 6 As shown, the inner wall of the chute 7 near the sealing plate 2 is flush with the outer wall of the sealing plate 2 near the chute 7, and a baffle 8 is slidably connected to the inner wall of the chute 7.

[0030] Two miniature electric push rods 9 are symmetrically fixed to the bottom surface of the window frame 1. The protruding ends of the miniature electric push rods 9 face downward and are fixed with connecting strips 10. The end of the connecting strip 10 away from the miniature electric push rods 9 is fixed to the bottom surface of a stop strip 8 at the lower end. Two synchronous moving components are symmetrically installed between the two stop strips 8. The synchronous moving components enable the two stop strips 8 to open and close synchronously.

[0031] When multiple sealing plates 2 rotate to close the window frame 1, such as Figure 4 In the state shown, the micro electric push rod 9 is then driven to retract, pulling one of the lower baffles 8 upward. With the cooperation of the synchronous moving component, one of the upper baffles 8 is lowered. The four sides of the two baffles 8 that are close to each other are chamfered, which makes it easier for the baffles 8 to slide into the side of the sealing plate 2. Then the two baffles 8 approach each other, and the side wall of the baffles 8 abuts against the outer wall of the sealing plate 2, thus completing the locking work of the sealing plate 2. The baffles 8 can prevent the sealing plate 2 from rotating and can withstand the impact on the sealing plate 2.

[0032] Compared with existing technologies, the mechanism for locking the sealing plate 2 is simpler, which greatly saves production and maintenance costs.

[0033] A cover 16 is fixed on the outer wall of the window frame 1 near the rotating component. The cover 16 covers the rotating component, the baffle 8, the miniature electric push rod 9 and the synchronous moving component, and can protect the rotating component and other structures.

[0034] Example 2, please refer to Figure 7 and Figure 8 This embodiment provides a further technical solution based on embodiment one. The synchronous moving component includes two extension bars 11 fixed at the same end of two stop bars 8. The ends of the two extension bars 11 that are close to each other extend to the middle of the window frame 1. The middle of the outer wall of the window frame 1 near the extension bar 11 is rotatably connected to a second gear 12 by a shaft pin. The two extension bars 11 are centrally symmetrical about the axis of the second gear 12. Two second racks 13 are meshed and connected to the outer side of the second gear 12 in a centrally symmetrical manner. A groove 14 is opened on the end of the extension bar 11 near the second rack 13 and the side near the second gear 12. The second rack 13 is fixed inside the groove 14. The tooth end face of the second rack 13 does not protrude from the groove 14.

[0035] A connecting sleeve 15 is slidably sleeved on the outer side of the middle part of the extension strip 11. One side of the connecting sleeve 15 is fixed to the outer wall of the window frame 1. The connecting sleeve 15 makes the extension strip 11 slide up and down more stably.

[0036] When the lower stop bar 8 slides upward, the extension bars 11 at both ends of the lower stop bar 8 slide upward. Through the cooperation of the second rack 13 and the second gear 12, the upper extension bar 11 slides downward, causing the upper stop bar 8 to slide downward at the same time, and the two stop bars 8 close. This achieves the effect of opening and closing the two stop bars 8, reducing the investment in power equipment. Only one stop bar 8 needs to be driven to move up and down to make both stop bars 8 move up and down.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
