[0017] Please refer to Figures 1-3 , the present utility model provides a technical solution: a tower pole anti-falling frame structure, including an L-shaped frame 1 and a support block 5. A connecting frame 2 is fixedly installed on the horizontal end of the L-shaped frame 1. A first ear plate 3 is provided at the lower end of the connecting frame 2. A second ear plate 4 is provided at the lower end of the vertical end of the L-shaped frame 1. The support block 5 is installed on the lower wall surface of the horizontal end of the L-shaped frame 1. A disassembly structure is provided between the support block 5 and the L-shaped frame 1.

[0018] In this embodiment, it is further set that the disassembly structure includes a through hole. The through hole is opened on the lower wall surface of the horizontal end of the L-shaped frame 1. An installation hole is opened on the support block 5. A hollow cylinder 6 is fixedly installed in the installation hole. The upper end of the hollow cylinder 6 penetrates through the installation hole. The hollow cylinder 6 is matched with the through hole. A lead screw 7 is rotatably installed between the upper and lower wall surfaces of the hollow cylinder 6. The lower end of the lead screw 7 is exposed outside the hollow cylinder 6. A limiting portion is provided at the lower end of the lead screw 7. Openings 8 are opened on both side wall surfaces of the hollow cylinder 6. A moving block 9 is slidably installed in the opening 8. A moving plate 10 is fixedly installed between the moving blocks 9. A threaded hole is opened on the moving plate 10. The moving plate 10 is meshed with the lead screw 7 through the threaded hole. The lower wall surface of the moving block 9 is hinged with a first connecting rod 11. The lower wall surface of the opening 8 is hinged with a second connecting rod 12. The first connecting rod 11 and the second connecting rod 12 are hinged to each other.

[0019] In this embodiment, it is further set that the limiting portion includes a reserved groove 13. The reserved groove 13 is opened on the lower wall surface of the support block 5. The reserved groove 13 communicates with the installation hole. A ratchet 14 is fixedly installed at the lower end of the lead screw 7. A pawl 15 is rotatably installed in the reserved groove 13 and on one side of the ratchet 14. A spring is provided between the pawl 15 and the reserved groove 13. The ratchet 14 is matched with the sharp claw.

[0020] In this embodiment, it is further set that the cross section of the support block 5 is in a semi-circular structure.

[0021] In this embodiment, it is further set that an anti-slip rubber ring 16 is provided on the inner wall surface of the through hole.

[0022] In this embodiment, it is further set that an internal hexagonal force-bearing block 17 is provided at the lower end of the lead screw 7.

[0023] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and the specific work is as follows.

[0024] Embodiment: As can be seen from the accompanying drawings of the specification, when in use, the hollow cylinder 6 on the support block 5 is inserted into the through hole at the horizontal end of the L-shaped frame 1. At this time, the inner hexagon force-bearing block 17 is rotated, so that the inner hexagon force-bearing block 17 drives the lead screw 7 to rotate. Through the cooperation of the ratchet 14 and the pawl 15, the reverse rotation of the ratchet 14 is prevented. Since the moving plate 10 and the lead screw 7 are meshed and connected through a threaded hole, when the lead screw 7 rotates, it has a driving force on the moving plate 10. The moving plate 10 moves downward along the path of the opening 8 under the action of the moving block 9. During the downward movement of the moving plate 10, the first connecting rod 11 and the second connecting rod 12 perform a supporting movement, so that the first connecting rod 11 and the second connecting rod 12 support above the through hole, so that the support block 5 is installed on the L-shaped frame 1. The curved surface of the support block 5 with a semicircular cross-section contacts the inclined frame of the line tower. Due to gravity and the action of the curved surface, the device can always be used perpendicular to the ground;

[0025] When it is necessary to disassemble the support block 5, the pawl 15 is toggled to separate the pawl 15 from the ratchet 14. Then, the lead screw 7 is rotated in the reverse direction, so that the first connecting rod 11 and the second connecting rod 12 coincide with the opening 8. At this time, the support block 5 is pulled downward, so that the support block 5 is separated from the L-shaped frame 1.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
