[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Please refer to Figures 1 - 6 A safety device for preventing high-rise buildings from falling includes a net bag unit 10 , a supporting unit 20 for supporting the net bag unit 10 to open, and a driving unit 30 for driving the supporting unit 20 . Figure 1 The building is provided with a plurality of the safety devices.

[0022] During specific use, the driving unit 30 drives the supporting unit 20 to move, and then the supporting unit 20 pushes the net bag unit 10 to open or close.

[0023] The net bag unit 10 includes a frame 11 and a ball net 12 arranged in the frame 11 .

[0024] The frame 11 includes a first frame end 11a for being rotatably mounted on a building wall and a second frame end 11b opposite to the first frame end 11a. Figure 5 As shown, in specific use, the first end 11a of the frame is rotatably disposed on the building wall, so that the frame 11 as a whole can rotate on the building wall.

[0025] The ball net 12 is a mesh structure and is disposed on the frame 11 , thereby making the net bag unit 10 a tool capable of catching falling people and objects.

[0026] like Figures 2 - 4 As shown, the ball net 12 includes a plurality of ball net units U, each of which includes a first connecting member 12a, a plurality of second connecting members 12b and a plurality of balls 12c. The first connecting member 12a, the second connecting member 12b and the balls 12c are all made of stainless metal, such as stainless steel. The ball net 12 made of stainless metal is not easy to rot and cut compared to the textile materials in the prior art while meeting the requirements of use.

[0027] like Figures 2 - 4 As shown, the first connecting member 12a is in a "cross" shape, and the four ends of the outer periphery of the first connecting member 12a are each connected to a ball 12c through a second connecting member 12b, and the balls 12c are connected to form a chain through the second connecting member 12b.

[0028] like Figures 3 - 4 As shown, the ball 12c is a hollow structure, and two through holes 12ca are provided on the ball 12c. The second connecting member 12b is in the shape of a rod, and the two ends of the second connecting member 12b extend into the through holes 12ca of two adjacent balls 12c, respectively. The ends of the two second connecting members 12b inside the ball 12c are respectively provided with magnets 12ba for adsorption connection, and the ends of the two second connecting members 12b inside the ball 12c are respectively provided with limiting protrusions 12bb for limiting, so as to prevent the second connecting member 12b from being separated from the through holes 12ca. The balls 12c on the periphery of each bead net unit U are connected to each other through the second connecting member 12b to form a whole.

[0029] like Figures 3 - 4As shown, the ball net 12 formed by the above structure is divided into two states, one of which is: two adjacent balls 12c are close together, and the magnets 12ba on the two second connecting members 12b in each ball 12c are adsorbed and connected. In this state, the whole formed by the connection of the ball 12c and the second connecting member 12b is in a straight line. The ball net 12 is in a convergent state as a whole, and each ball 12c is connected to the second connecting member 12b and the first connecting member 12a to form an overall compact structure, and the ball net 12 is in a flat plate shape as a whole. Another state is formed: under the action of external force, the two second connecting members 12b in each ball 12c are separated from each other, and the second connecting member 12b is stretched outward, and the limiting protrusions 12bb at both ends of the second connecting member 12b are limited at the periphery of the through hole 12ca, and the second connecting member 12b cannot be separated from the ball 12c. In this state, the balls 12c and the second connecting member 12b on a line are pulled apart, increasing the overall length, and the ball net 12 changes into a net bag shape. The above two states can be transformed into each other under the action of external force.

[0030] The ball net 12 as a whole formed by the ball 12c, the first connecting member 12a and the second connecting member 12b will not get tangled or caught, and is neater, safer and smoother to use than the prior art.

[0035] In the specific implementation process, Figure 5 As shown, the cylinder 31 extends the telescopic rod 31b, thereby pushing the first support end 22a to slide upward; the cylinder 31 retracts the telescopic rod 31b, thereby pulling the first support end 22a to slide downward.

[0036] In a specific implementation, the cylinder 31 may also be arranged in other directions, and the action may be transmitted to the support rod 22 through a connecting rod mechanism.
