[0022] Embodiment 1

[0023] A quick deployment device for an anti-fall net with an adjustable deployment angle comprises a mounting seat 1, a pop-up rod 2, an adjustment component and an auxiliary component; the mounting seat 1 is fixedly arranged on a wall, the pop-up rod 2 is hingedly arranged at the lower end of the mounting seat 1, a mounting plate 5 is fixedly arranged on the side wall of the pop-up rod 2, a damping rod 3 is installed on the mounting seat 1, and the end of the damping rod 3 is connected to the mounting plate 5; an electric pull rod 4 is installed on the mounting seat 1, a pull-back rope is installed at the end of the electric pull rod 4, the pull-back rope is passed around a pulley and fixedly connected to the mounting plate 5, and a reserved hole for installing the anti-fall net is opened on the mounting plate 5; an adjustment component and an auxiliary component are arranged at the connection between the mounting seat 1 and the pop-up rod 2; the adjustment component comprises a convex plate 6, an arc groove 7, a motor 8, a worm 9, a worm wheel 10, a blocking column 11, a slider 12, a connecting column 13 and a connecting plate 14; the auxiliary component comprises a U-shaped plate 15, a rubber pad 16, a mounting hole 17 and a positioning hole 18.

[0024] When in use, the anti-fall net is installed on the mounting plate 5, and the electric lock arranged on the mounting seat 1 locks the lock buckle on the mounting plate 5. When encountering danger, the electric lock is unlocked, and the damping rod 3 extends to pop out the pop-up rod 2 from the mounting seat 1 until the rubber pad 16 installed on the damping rod 3 is engaged with the blocking column 11 to complete the rotation angle limit of the damping rod 3. At this time, the anti-fall net is quickly deployed; when recovering, the electric pull rod 4 works to drive the pull-back rope, and the pull-back rope pulls the mounting plate 5 to reset the pop-up rod 2 and the mounting plate 5 until the lock buckle on the mounting plate 5 is locked again by the electric lock arranged on the mounting seat 1.

[0025] Embodiment 2, based on embodiment 1:

[0026] The convex plate 6 in the adjustment assembly is symmetrically fixed on the side wall of the mounting seat 1, the convex plate 6 is located on both sides of the pop-up rod 2, the end of the convex plate 6 is arranged in an arc shape, and an arc groove 7 is opened on the convex plate 6; the motor 8 is fixed on the side wall of the convex plate 6, and the output shaft of the motor 8 is fixedly provided with a worm 9, and the worm wheel 10 is rotatably arranged on the side wall of the convex plate 6 through a rotating shaft; the two ends of the blocking column 11 are symmetrically fixed with sliders 12, the connecting column 13 is fixedly provided at the side end of the slider 12, and the two ends of the connecting plate 14 are respectively fixedly connected to the worm wheel 10 and the connecting column 13; the worm 9 and the worm wheel 10 are arranged in corresponding positions and the same number of groups, and the two are meshed; the arc groove 7 and the slider 12 are arranged in corresponding positions and the same number of groups, and the slider 12 is movably engaged in the arc groove 7.

[0027] When in use, the motor 8 drives the worm 9 to rotate, and the worm 9 drives the worm wheel 10 to rotate.

After adjusting the position of the blocking column 11, the motor 8 is adjusted to work, and the pop-up rod 2 pops out until it is engaged with the blocking column 11. At this time, a certain angle is formed between the pop-up rod 2 and the mounting seat 1. After a person falls on the inclined anti-fall net, he will rebound toward the wall, preventing people from rolling out directly from the anti-fall net, thereby reducing the hidden dangers of using the anti-fall net.
