[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] The present invention provides the following preferred embodiments: Examples, such as Figures 1-7 As shown, a building safety net support frame that is easy to fold and store includes a safety net 1, as well as a flipping mechanism and a storage mechanism; The flipping mechanism includes a wedge block 18, two telescopic components, two flipping components, and two limiting components. The two telescopic components are respectively arranged on both sides of the safety net 1. Each flipping component is arranged between one telescopic component, and each limiting component is arranged between one telescopic component and one flipping component. The storage mechanism includes two telescopic components and multiple connecting components. The two rotating components are located on both sides of the two telescopic components, and the multiple connecting components are respectively located on the two rotating components.

[0024] like Figures 1-3 As shown, each telescopic component includes two guide plates 2, two telescopic grooves 3, two telescopic rods 4 and two sliders 5. Each guide plate 2 is disposed on one side of a vertical plate, each telescopic groove 3 is opened on one side of a guide plate 2, each telescopic rod 4 is slidably disposed inside a guide plate 2, and each slider 5 is slidably disposed on one side of a telescopic rod 4, and each slider 5 is slidably connected to a telescopic groove 3. When the safety net 1 needs to be stored for the first time, the safety net 1 is initially folded by controlling the telescopic component. When the safety net 1 needs to be stored for the second time, the guide plate 2 on one side is pushed manually so that the two telescopic rods 4 slide into the telescopic groove 3 respectively, reducing the volume first. Then, the area of ​​the safety net 1 is further reduced by manually grasping the guide plate 2 on one side.

[0025] like Figures 4-6 As shown, each flipping mechanism includes a hinge shaft 6, a rotating plate 7, and a rotating seat 8. The rotating plate 7 is fixedly disposed at one end of one of the rotating seats 8 away from the guide plate 2, and the rotating seat 8 is fixedly disposed at the other end of the telescopic rod 4 away from the guide plate 2. The hinge shaft 6 is rotatably disposed between the rotating plate 7 and the rotating seat 8. When it is necessary to fold the safety net 1, the guide plate 2 on one side is manually grasped. The guide plate 2 drives a telescopic rod 4 and a rotating plate 7, so that the rotating plate 7 rotates around the hinge shaft 6 on the rotating seat 8, thereby folding the safety net 1 and reducing its area.

[0026] like Figures 5-7As shown, the limiting assembly includes a rotating shaft 10, an L-shaped plate 11, a locking rod 12, a locking groove 13, a sliding groove 15, a lever 16, a lever groove 17, and two springs 14. The rotating shaft 10 is fixedly mounted on one side of one of the rotating seats 8. The L-shaped plate 11 is rotatably mounted on the end of the rotating shaft 10 away from the telescopic rod 4. The locking rod 12 is fixedly mounted on the end of the L-shaped plate 11 away from the rotating shaft 10. The locking groove 13 is opened on the top of the other telescopic rod 4. The sliding groove 15 is opened on one side of the locking groove 13. The lever groove 17 is opened on the top of the telescopic rod 4 and is located above the sliding groove 15. The wedge block 18 is slidably connected to the sliding groove 15. The lever 16 is slidably mounted in the lever groove 17 and is fixedly connected to the wedge block 18. Each spring 14 is mounted in the sliding groove 15, and both ends of each spring 14 are fixedly connected to the wedge block 18 and the sliding groove 15, respectively. When it is necessary to fix the folded safety net 1, manually move the L-shaped plate 11 to rotate it around the rotating shaft 10, so that the locking rod 12 on one side enters the locking groove 13. When the locking rod 12 enters the locking groove 13, the locking rod 12 will abut against the wedge block 18. As the locking rod 12 descends, the wedge block 18 will slide inside the sliding groove 15 under the abutment of the locking rod 12. At this time, the two springs 14 are compressed. As the locking rod 12 continues to descend until the locking rod 12 passes the wedge block 18, the wedge block 18 will reset under the action of the two springs 14. At this time, the locking rod 12 can be fixed, thereby fixing the folded safety net 1. When the wedge block 18 moves, it will drive the lever 16 to move together. When it is necessary to open the folded safety net 1, the lever 16 is manually grasped and slid in the slot 17. At this time, the lever 16 will drive the wedge block 18 to move in the sliding groove 15. Then the L-shaped plate 11 can be rotated to drive the locking lever 12 to leave the slot 13 and open the folded safety net 1.

[0027] like Figures 1-3As shown, each telescopic component includes a motor 19, a lead screw 20, a first guide rod 21, two second guide rods 29, two limiting blocks 22, two movable blocks 23, two L-shaped frames 28, several first connecting rods 30, and several second connecting rods 31. Each first connecting rod 30 and each second connecting rod 31 are arranged vertically and alternately, and the middle of each first connecting rod 30 and each second connecting rod 31 is hinged to each other. The ends of adjacent first connecting rods 30 and second connecting rods 31 are hinged to each other. The first connecting rods 30 and second connecting rods 31 at both ends are hinged to the limiting blocks 22 and the movable blocks 23, respectively. Each limiting block 22 is fixedly mounted on a guide plate 2. On one side, each L-shaped frame 28 is fixedly installed at one end of a guide plate 2. A motor 19 is fixedly installed on one side of one of the L-shaped frames 28. A lead screw 20 is rotatably installed between one of the limiting blocks 22 and one L-shaped frame 28, and one end of the lead screw 20 is fixedly connected to the output end of the motor 19. The first guide rod 21 is located on one side of the lead screw 20 and is fixed between the limiting block 22 and the L-shaped frame 28. Each second guide rod 29 is fixedly installed between another limiting block 22 and another L-shaped frame 28. One movable block 23 is sleeved on the lead screw 20 and the first guide rod 21 and is threadedly connected to the lead screw 20. The other movable block 23 is slidably sleeved on the two second guide rods 29. When the safety net 1 needs to be stored, the controller controls the motor 19 to work, the motor 19 drives the lead screw 20 to rotate, the lead screw 20 drives the movable block 23 away from the limit block 22 on one side, thereby increasing the angle between the first link 30 and the second link 31, which in turn causes the safety net 1 to shrink and be stored. When the safety net 1 needs to be opened, the controller controls the motor 19 to work, controls the lead screw 20 to rotate in the opposite direction, so that the movable block 23 moves closer to the limit block 22 on one side. Through the first link 30 and the second link 31, multiple connecting blocks 26 can be moved, so that the distance between multiple connecting blocks 26 located on the same side of the safety net 1 can be continuously reduced, thereby unfolding the safety net 1.

[0028] like Figures 1-2As shown, each connecting component includes a limiting piece 32, a connecting block 26, and a connecting shaft 27. The limiting piece 32 is fixedly mounted on the safety net, the connecting shaft 27 is fixedly mounted on the limiting piece 32, and the connecting block 26 is fixedly mounted on the top of the connecting shaft 27. Each first link 30 and each second link 31 is hinged at one end to the end of a connecting block 26 away from the limiting piece 27. Specifically, the end of the connecting block 26 away from the connecting shaft 27 is fixed with a hinge shaft, and the ends of the first link 30 and the second link 31 near the connecting block 26 are rotatably mounted on the hinge shaft. When the slider 24 moves, it will drive the fixing bolt 27 to move together. When the fixing bolt 27 moves, it will drive the collar 25 and the connecting rod 26 sleeved on the fixing bolt 27 to move together. The connecting rod 26 drives one corner of the safety net 1 to move, and multiple collars 25 drive multiple corners of the safety net 1 to move, making it convenient to unfold and store the safety net 1.
