[0013] The present invention provides a safety anti-falling structure for construction engineering, which has the following beneficial effects: 1. The present invention provides a fall protection mechanism. When a faller falls, the faller contacts with several rubber strips on the elastic net, which can block the faller to a certain extent through the rubber strips, thereby increasing the friction between the faller and the surface of the elastic net. The rubber strips are made of elastic material, which can protect the faller to a certain extent and effectively prevent the faller from falling off the elastic net due to the lateral component of force after falling to the edge of the elastic net, thereby stably supporting and protecting the faller.
[0014] 2. The present invention sets a fall protection mechanism, thereby limiting its air intake speed, and also limiting the speed at which the sliding rod A, sliding sleeve A, sliding sleeve B, sliding sleeve C and sliding rod B are pulled and reset by the hinged rod A. Similarly, the hinged rod A, hinged rod B and connecting rod are pulled and reset at a limited speed by the elastic net, so that the elastic net cannot rebound quickly. Then, the faller who falls on the elastic net will not be wrapped by the elastic net and then bounced out again by the elastic force of the elastic net, which will cause the impact force of the faller to be too large, and the problem of being bounced out of the elastic net will occur. The elastic force of the elastic net is used to cushion the fall of the faller to a certain extent, and at the same time, it is slowly reset, which further improves the guarantee of the personal safety of the faller.
[0015] 3. The present invention provides a fall protection mechanism. When a faller falls quickly onto the elastic net, the elastic net and the hinged rod A will drop quickly, and the air in the sliding sleeve B will be quickly squeezed and discharged through the one-way air outlet valve. When the air is discharged through the one-way one-way air outlet valve, a whistle sound will be generated inside the one-way air outlet valve, and the air discharge at this time is an explosive discharge. Therefore, when passing through the one-way air outlet valve, the whistle sound generated is relatively intense. The surrounding staff can quickly realize that a situation has occurred there, and then quickly rescue the patient, thereby avoiding the problem of untimely rescue after the patient falls.
[0016] 4. The present invention provides a stabilizing mechanism so that even if the faller falls onto any point on the elastic net, the entire elastic net can fall evenly as a whole, thereby preventing the faller from falling directly into the elastic net and being completely wrapped by the elastic net when falling onto the elastic net quickly, causing the limb joints to be laterally squeezed by the elastic net and causing fractures. At the same time, each one-way air outlet valve on the sliding sleeve B will produce a whistle, further enhancing the stable fall prevention and rescue and the protection of the faller.

DETAILED DESCRIPTION
[0019] Example 1: Please refer to Figure 1-4 The present invention provides a technical solution: a safety anti-falling structure for construction engineering, comprising a fixed frame 1, a spring 2 is fixedly connected to the inner wall of the fixed frame 1, an elastic net 5 is fixedly connected to one end of the spring 2, and a fall protection mechanism 3 is arranged on the outer wall of the elastic net 5; The fall protection mechanism 3 comprises: The rubber strip 313 is an annular strip structure, and the rubber strip 313 is fixedly connected to the surface of the elastic net 5. The bottom of the elastic net 5 is fixedly connected with a connecting rod 305, and the connecting rod 305 is a circular columnar structure. The bottom of the connecting rod 305 is fixedly connected with a hinged rod B304, and one end of the hinged rod B304 is fixedly connected with a hinged rod A303. The rubber strip 313 is used to prevent a falling person from rolling left and right on the elastic net 5; The hinge block 301, the top of the hinge block 301 is fixedly connected to the bottom of the spring 2, the inner wall of the hinge block 301 is rotatably connected to the rotating shaft 302, the outer wall of the rotating shaft 302 is fixedly connected to one end of the hinge rod A303, and the hinge block 301 is used to support the rotating shaft 302; When workers in construction projects are working at high altitudes, the fixed frame 1 is placed below the workers and fixed to the periphery of the building. Then, if the workers fall unexpectedly, they will fall directly onto the elastic net 5 in the middle of the fixed frame 1. Then, the elastic net 5 will sink and wrap the falling personnel. The elastic force of the sinking elastic net 5 will cushion the falling personnel, and the elastic net 5 will be pulled by several springs 2 around the elastic net 5, thereby effectively protecting the personal safety of the falling personnel. Example 2: Please refer to Figure 1-8 On the basis of the first embodiment, the present invention provides a technical solution: the bottom of the hinged rod A303 is fixedly connected with a sliding rod A306, the outer wall of the sliding rod A306 is slidably connected with a sliding sleeve A307, and the outer wall of the sliding sleeve A307 is slidably connected with a sliding sleeve B308.
[0020] The inner wall of the sliding sleeve B308 is slidably connected to a sliding sleeve C309, the inner wall of the sliding sleeve C309 is slidably connected to a sliding rod B310, and one end of the sliding rod B310 is fixedly connected to the outer wall of the spring 2.
[0021] The sliding rod B310, the sliding sleeve C309, the sliding sleeve B308, the sliding sleeve A307, and the sliding sleeve A307 are all arc-shaped rod structures, and the arc center is at the same position as the center of the rotating shaft 302.
[0022] A one-way air inlet valve 311 is provided on the outer wall of the sliding sleeve B308, and a one-way air outlet valve 312 is provided on the outer wall of the sliding sleeve B308. The interior of the one-way air outlet valve 312 is communicated with the interior of the sliding sleeve B308, and the interior of the one-way air inlet valve 311 is communicated with the interior of the sliding sleeve B308. After the falling person falls on the elastic net 5, the elastic net 5 wraps the falling person and the falling person comes into contact with the rubber strip 313 on the elastic net 5. Once the falling person falls to the edge of the elastic net 5, the elastic force is relatively large due to the pulling of the spring 2 around the elastic net 5. The elastic net 5 will be deformed into a slope, and the falling person will naturally roll toward the center of the elastic net 5. Once the falling speed is fast, the vertical falling force will be converted into a lateral force due to the slope on the elastic net 5, causing the falling person to roll toward the center of the elastic net 5 and As the inertia continues to roll, the problem of rolling directly to the outside of the elastic net 5 occurs. At this time, the faller is contacted with the several rubber strips 313 on the elastic net 5, and the rubber strips 313 will block the faller to a certain extent, thereby increasing the friction between the faller and the surface of the elastic net 5. The rubber strips 313 are made of elastic material, which has a certain effect of protecting the faller, and effectively prevents the faller from falling to the side of the elastic net 5 and rolling away from the elastic net 5 with the lateral component of the force, thereby stably supporting and protecting the faller. After the elastic net 5 sinks, the bottom of the elastic net 5 will drive the connecting rod 305 to descend synchronously, and the connecting rod 305 will drive the hinged rod B304 and the hinged rod A303 to hinge and rotate with the rotating shaft 302 in the inner wall of the hinge block 301, thereby pushing the original horizontal state of the hinged rod A303 and the hinged rod B304 to a downward inclined state. When the hinged rod A303 is hinged and rotated, it will also drive the hinged rod B304 to rotate in a concentric circle with the rotating shaft 302. The sliding rod A306, the sliding sleeve A307, the sliding sleeve B308, the sliding sleeve C309 and the sliding rod B310 are retracted with each other, and the interior of the sliding sleeve B308 is in a sealed state. When the sliding sleeve C309 and the sliding sleeve A307 are retracted into the sliding sleeve B308, the air is squeezed out through the one-way air outlet valve 312. When the elastic net 5 sinks and begins to rebound with its own elastic force, the air intake inside the sliding sleeve B308 is Air is taken in through the one-way air intake valve 311 with a smaller diameter. The one-way air intake valve 311 has a smaller diameter, which limits its air intake speed, and also limits the speed at which the sliding rod A306, the sliding sleeve A307, the sliding sleeve B308, the sliding sleeve C309 and the sliding rod B310 are pulled and reset by the hinged rod A303. Similarly, the hinged rod A303, the hinged rod B304 and the connecting rod 305 are pulled and reset by the elastic net 5, so that the elastic net 5 cannot rebound quickly. Then, the faller who falls on the elastic net 5 will not be wrapped by the elastic net 5 and then bounced out again by the elastic force of the elastic net 5, which will cause the faller to fall too much, and the problem of being bounced out of the elastic net 5 will occur. The elastic force of the elastic net 5 is used to cushion the faller to a certain extent and reset slowly, which further improves the guarantee of the faller's personal safety. At the same time, when the faller falls onto the elastic net 5 quickly, the elastic net 5 and the hinge rod A303 will drop quickly, and the air in the sliding sleeve B308 will be squeezed quickly and discharged through the one-way air outlet valve 312. When the air is discharged through the one-way one-way air outlet valve 312, a whistle sound will be generated inside the one-way air outlet valve 312, and the air discharge at this time is an explosive discharge. Therefore, when passing through the one-way air outlet valve 312, the whistle sound generated is relatively intense, and the surrounding staff can quickly realize that something has happened there, and then quickly rescue the patient, avoiding the problem of delayed rescue after the patient falls. Example 3: Please refer to Figure 1-12 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a stabilizing mechanism 4 is provided at one end of the hinged rod B304, the stabilizing mechanism 4 comprises a fixed shaft A401, one end of the fixed shaft A401 is fixedly connected to one end of the hinged rod B304, a circular sleeve 402 is fixedly connected to the outer wall of the fixed shaft A401, and a fixed shaft B403 is fixedly connected to the inner wall of the circular sleeve 402.
[0023] One end of the fixed shaft B403 is fixedly connected with a rotating ball 404 , the outer wall of the rotating ball 404 is slidably connected with a fixed block 405 , and the rotating ball 404 is embedded in the inner wall of the fixed block 405 .
[0024] The outer wall of the fixed block 405 is fixedly connected with a fixed frame 406, the top of the fixed frame 406 is fixedly connected with a telescopic rod 407, and the top of the telescopic rod 407 is fixedly connected with the bottom of the elastic net 5; When the faller falls to the outer position of the elastic net 5, the elastic net 5 falls and pushes the connecting rod 305 to the hinge rod B304 and the hinge rod A303 to hinge and rotate downward. When the hinge rod B304 rotates and descends, it will drive the fixed shaft A401 and the circular sleeve 402 to descend. The descent of the circular sleeve 402 drives the fixed shaft B403 to descend. The fixed shaft B403 drives the fixed block 405 to descend through the rotating ball 404, and the fixed block 405 is restricted by the telescopic rod 407 so that it can only be lifted vertically. The fixed block 405 is wrapped by the telescopic rod 407 through the fixed frame 406, and the fixed shaft B403 is embedded in the fixed block 405 through free rotation to pull the fixed block 405 to descend vertically. Therefore, even when one side of the elastic net 5 is squeezed and descended by the faller, it will still drive the fixed shaft B403 to the fixed block 405 to descend through one of its hinged rods B304. The descent of the fixed block 405 will drive all the rotating balls 404 and the fixed shaft B403 connected thereto to descend, thereby finally causing the fixed block 405 to descend vertically, driving all the rotating balls 404 and the fixed shaft B403, the hinged rod B304, and the connecting rod 305 connected thereto to descend simultaneously. By the simultaneous descent of all the connecting rods 305, the entire elastic net 5 is synchronously pulled downward, so that even if the faller falls on any point on the elastic net 5, the entire elastic net 5 can be made to fall evenly as a whole, thereby preventing the faller from falling directly into the elastic net 5 and being completely wrapped by the elastic net 5 when falling on the elastic net 5 quickly, causing the limb joints to be squeezed laterally by the wrapping of the elastic net 5 and causing fractures. At the same time, the one-way air outlet valve 312 on each sliding sleeve B308 will produce a whistle, further enhancing the stable fall prevention and rescue and the protection of the faller.
[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
