[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a high-safety protective net, comprising an outer frame and two fixed plates on both sides, wherein symmetrical swing seats are provided on the outer wall of the outer frame, and a slot is formed in the middle of the swing seats; a swing plate that cooperates with the swing seats is provided on the outer wall of the fixed plates, and a screw rod that passes through the slot is fixedly provided on the outer wall of the swing plate, and a nut is threaded onto the screw rod; symmetrical sliding grooves are provided on the inner wall of the outer frame, and a safety net is slidably installed between the sliding grooves; a winding drum is also movably installed between the outer frames, and a spring is provided in the middle of the winding drum; a limiting groove is also provided on the outer side of the outer frame, and a secondary net frame is slidably installed in the limiting groove.

[0007] As a further embodiment of this utility model: symmetrical motors are installed on the outer wall of the outer frame, and the output end of the motor is provided with a threaded rod located in the slide groove. Slider blocks are installed on both sides of the safety net and are slidably disposed in the slide groove. A through threaded hole is opened in the middle of the slider.

[0008] As a further improvement of this utility model, the bottom of the sub-grid is provided with a limiting slide that cooperates with the limiting groove.

[0009] As a further improvement of this utility model, multiple sets of positioning bolts are installed on the fixing plate.

[0010] As a further improvement of this utility model, the safety net is made of polyethylene.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention utilizes a motor to quickly retract the safety net. As the slider moves outward along the threaded rod, the spring inside the winding drum tightens. When the slider moves inward along the threaded rod, the safety net winds onto the winding drum under the action of the spring. A detachable secondary net frame further enhances the device's strength. With the cooperation of the swing seat and swing plate, the angle of the outer frame can be adaptively adjusted according to actual needs. This design improves the stability and freedom of movement of this high-safety protective net. Attached Figure Description
