All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figures 1 to 4 The utility model provides a technical solution: a locking structure for a campus building anti-fall net rapid deployment device, comprising: a fixed plate 4 and a movable plate 6, an anti-fall net 9 is fixed between the fixed plate 4 and the movable plate 6, the movable plate 6 is slidably connected between two sets of guide rails 5, a locking groove 15 is opened on the surface of the movable plate 6, a locking rod 11 is movably inserted on the surface of the guide rail 5, the other end of the locking rod 11 is movably inserted in the locking groove 15, an inclined surface is provided on the portion where the locking rod 11 is movably inserted in the locking groove 15, a bracket 3 is fixed to the bottom end of the fixed plate 4, a wall 1 is provided on the side of the bracket 3, and a floor 2 is provided on the surface of the wall 1.

[0021] When the movable plate 6 moves to the end of the bracket 3 away from the floor 2, it will be automatically limited by the locking rod 11, thereby realizing the function of automatically locking the end of the anti-falling net 9 away from the floor 2, and there is no need for construction personnel to perform high-altitude operations.

[0022] Embodiment 2

[0023] On the basis of Example 1, in order to achieve rapid deployment of the anti-fall net 9, one end of the first rotating rod 7 is rotatably connected to the surface of the fixed plate 4, one end of the second rotating rod 8 is rotatably connected to the surface of the movable plate 6, the other end of the first rotating rod 7 and the other end of the second rotating rod 8 are hinged, and a bracket 3 is fixed to the bottom end of the fixed plate 4, a wall 1 is provided on the side of the bracket 3, and a floor 2 is provided on the surface of the wall 1.

[0024] When unfolding the anti-falling net 9, the construction worker only needs to stand on the floor 2 and then press the first rotating rod 7 downward to make the first rotating rod 7 rotate downward around the fixed plate 4. The rotation of the first rotating rod 7 drives the end of the second rotating rod 8 fixed on the first rotating rod 7 to also rotate downward. The rotation of the first rotating rod 7 generates a component force in the horizontal direction on the second rotating rod 8, which is directed away from the wall 1. The movement of the second rotating rod 8 generates a component force in the horizontal direction on the movable plate 6 away from the wall 1, thereby causing the movable plate 6 to move in the direction away from the wall 1, thereby realizing the rapid deployment of the anti-falling net 9.

[0025] Embodiment 3

[0026] On the basis of Example 2, in order to replace the anti-fall net 9, a sleeve 10 is fixed on the surface of the guide rail 5, one end of the locking rod 11 is movably inserted in the sleeve 10, and a pull rope 12 and a spring 13 are fixed to the end of the locking rod 11 extending into the sleeve 10, and the other end of the spring 13 is fixed to the inner wall of the sleeve 10, and the other end of the pull rope 12 extends from the end of the sleeve 10 away from the guide rail 5, and a pulley 14 is rotatably connected to the surface of the guide rail 5, and the pull rope 12 is overlapped on the surface of the pulley 14.

[0027] The two ends of the anti-falling net 9 are fixed to the fixed plate 4 and the movable plate 6 by gluing. When the anti-falling net 9 needs to be replaced, the construction personnel only need to stand on the wall 1 and pull the pull rope 12. The pull rope 12 changes direction through the pulley 14, thereby generating a pulling force close to the sleeve 10 on the locking rod 11, so that the locking rod 11 is completely retracted into the sleeve 10 and withdrawn from the locking groove 15, so that the limit of the movable plate 6 can be released, and then the first rotating rod 7 is pulled upward to rotate the first rotating rod 7 upward along the fixed plate 4, and the first rotating rod 7 drives the second rotating rod 8 to rotate upward around the movable plate 6, so that A horizontal component force is generated on the movable plate 6 in a direction toward the wall 1, so that the movable plate 6 approaches the fixed plate 4, and then a sol is sprayed on the fixed plate 4 and the movable plate 6 to dissolve the glue used to fix the anti-fall net 9. After the anti-fall net 9 is removed from the fixed plate 4 and the movable plate 6, the sol is wiped off, and then the two ends of the new anti-fall net 9 are respectively fixed to the fixed plate 4 and the movable plate 6 by glue, and then the anti-fall net 9 is unfolded again in the same way as in Example 2, and the end of the anti-fall net 9 away from the wall 1 is locked in the same way as in Example 1, and the replacement of the anti-fall net 9 is completed.

[0028] Embodiment 4

[0029] On the basis of Example 3, in order to realize that the locking rod 11 is automatically inserted into the locking groove 15 after the locking rod 11 is aligned with the locking groove 15, a sleeve 10 is fixed on the surface of the guide rail 5, one end of the locking rod 11 is movably inserted in the sleeve 10, and a pull rope 12 and a spring 13 are fixed to the end of the locking rod 11 extending into the sleeve 10, the other end of the spring 13 is fixed to the inner wall of the sleeve 10, the other end of the pull rope 12 extends from the end of the sleeve 10 away from the guide rail 5, and a pulley 14 is rotatably connected to the surface of the guide rail 5, and the pull rope 12 is overlapped on the surface of the pulley 14.

[0030] When the locking rod 11 is fully retracted into the surface of the guide rail 5, one end of the locking rod 11 will be inserted into the sleeve 10, which compresses the spring 13. When the locking rod 11 is aligned with the locking groove 15, the thrust generated by the spring 13 on the locking rod 11 under its own elasticity will push the locking rod 11 into the locking groove 15, thereby achieving the goal that after the locking rod 11 is aligned with the locking groove 15, the locking rod 11 is automatically inserted into the locking groove 15.

[0031] Embodiment 5

[0032] On the basis of the fourth embodiment, in order to prevent the end of the pull rope 12 away from the locking rod 11 from falling down and out of reach, a rope end fixing rod 16 is fixed on the surface of the fixing plate 4, and the end of the pull rope 12 away from the locking rod 11 is movably inserted on the surface of the rope end fixing rod 16, and a pull block 17 is fixed on the end of the pull rope 12 away from the locking rod 11, and the pull block 17 is against the surface of the rope end fixing rod 16.

[0033] In actual use, one end of the anti-falling net 9 is directly fixed to the surface of the fixed plate 4, and the other end of the anti-falling net 9 is fixed to the surface of the movable plate 6. When the anti-falling net 9 is unfolded, the movable plate 6 is moved along the two sets of guide rails 5 in the direction away from the fixed plate 4. When the rod body of the movable plate 6 is against the inclined surface of the locking rod 11, the movable plate 6 continues to move in the direction away from the fixed plate 4, which will push the end of the locking rod 11 extending out of the surface of the guide rail 5, so that the locking rod 11 is completely retracted into the surface of the guide rail 5. As the movable plate 6 continues to move in the direction away from the fixed plate 4 until the locking rod 11 is aligned with the locking groove 15, the locking rod 11 will automatically insert into the locking groove 15, thereby limiting the movable plate 6. The end of the anti-falling net 9 fixed on the fixing plate 4 is originally fixed to the top of the bracket 3. After the movable plate 6 moves to the end of the bracket 3 away from the floor 2, it will be automatically limited by the locking rod 11, thereby realizing the function of automatically locking the end of the anti-falling net 9 away from the floor 2, and there is no need for construction workers to perform high-altitude operations; when the anti-falling net 9 is unfolded, the construction workers only need to stand on the floor 2 and then press the first rotating rod 7 downward to make the first rotating rod 7 rotate downward around the fixing plate 4. The rotation of the first rotating rod 7 drives the end of the second rotating rod 8 fixed on the first rotating rod 7 to also rotate downward. The rotation of the first rotating rod 7 generates a component force in the horizontal direction on the second rotating rod 8, and the direction is toward the side away from the wall 1. The movement of the second rotating rod 8 generates a component force in the horizontal direction away from the wall 1 on the movable plate 6, so that the movable plate 6 moves in the direction away from the wall 1, and the anti-falling net 9 is quickly deployed; the two ends of the anti-falling net 9 are fixed to the fixed plate 4 and the movable plate 6 by gluing. When the anti-falling net 9 needs to be replaced, the construction personnel only need to stand on the wall 1 and pull the pull rope 12, and the pull rope 12 changes direction through the pulley 14, thereby generating a pulling force close to the sleeve 10 on the locking rod 11, so that the locking rod 11 is completely retracted into the sleeve 10 and withdrawn from the locking groove 15, so that the limit of the movable plate 6 can be released, and then the first rotating rod 7 is pulled upward to make the first rotating rod 7 move along the fixed The fixed plate 4 rotates upward, and the first rotating rod 7 drives the second rotating rod 8 to rotate upward around the movable plate 6, thereby generating a horizontal component force on the movable plate 6 in a direction close to the wall 1, so that the movable plate 6 approaches the fixed plate 4, and then the glue used to fix the anti-falling net 9 is dissolved by sprinkling a sol on the fixed plate 4 and the movable plate 6. After the anti-falling net 9 is removed from the fixed plate 4 and the movable plate 6, the sol is wiped off, and then the two ends of the new anti-falling net 9 are respectively fixed to the fixed plate 4 and the movable plate 6 by glue, and then the anti-falling net 9 is unfolded again in the same way as in the second embodiment, and the end of the anti-falling net 9 away from the wall 1 is locked in the same way as in the first embodiment, and the replacement of the anti-falling net 9 is completed;When the locking rod 11 is fully retracted to the surface of the guide rail 5, one end of the locking rod 11 will be inserted into the sleeve 10, which compresses the spring 13. When the locking rod 11 is aligned with the locking groove 15, the thrust generated by the spring 13 on the locking rod 11 under its own elasticity will push the locking rod 11 into the locking groove 15, so that after the locking rod 11 is aligned with the locking groove 15, the locking rod 11 is automatically inserted into the locking groove 15; in order to prevent the end of the pull rope 12 away from the locking rod 11 from falling down and being unable to reach it, a rope end fixing rod 16 is fixed on the surface of the fixing plate 4, and the end of the pull rope 12 away from the locking rod 11 is movably plugged on the surface of the rope end fixing rod 16, and a pull block 17 is fixed on the end of the pull rope 12 away from the locking rod 11, and the pull block 17 is against the surface of the rope end fixing rod 16. ;
