DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Reference Figure 1-5 A pole tower anti-fall device comprises a main frame 1, and the front and back of the main frame 1 are provided with adjustment grooves 2. The adjustment grooves 2 can limit the position of the control rod 3 to ensure that the control rod 3 can be stably extruded and fixed when in use, which is beneficial to improving the stability of the equipment. The adjustment grooves 2 are inclined, and the inclination angle of the adjustment grooves 2 is twenty degrees. The inner side of the adjustment grooves 2 is movably sleeved with the control rod 3. The outer surface of the control rod 3 is provided with fixing threads 5 near the front and back, and the fixing threads 5 are movably sleeved with fixing bolts 6. A first connecting rod 7 is provided on the side of the fixing bolt 6 near the center of the fixing threads 5. The first connecting rod 7 is movably sleeved with the control rod 3. A limiting groove 18 is provided on the top of the main frame 1, and a clamping block 4 is movably sleeved on the inner side of the limiting groove 18. The bottom of the first connecting rod 7 is fixedly connected with a control outer cylinder 8.

[0025] Reference Figure 2-5Described, the inner bottom of the clamping block 4 is fixedly connected with a first anti-slip groove 12 near one side, and the inner side of the main frame 1 is fixedly connected with a second anti-slip groove 19 at the top of the first anti-slip groove 12. The first anti-slip groove 12 and the second anti-slip groove 19 on the clamping block 4 can increase the friction between the climbing rope and the climbing rope. In this way, emergency fixation is performed to improve the reliability of equipment use. The left and right sides of the clamping block 4 are fixedly connected with a first spring 13 near the bottom. A bottom limit block 16 is provided on the inner side of the first spring 13 near the bottom. The bottom of the bottom limit block 16 is fixedly connected with the fixing bolt 6, and a top limit block 17 is provided on the inner side of the first spring 13 near the top. The top limit block 17 is provided to ensure that the clamping block 4 and the main frame 1 can be spread apart during normal climbing to avoid unnecessary extrusion between the clamping block 4, the main frame 1 and the climbing rope, which causes the user to consume unnecessary force when climbing. The bottom of the top limit block 17 is fixedly connected with the main frame 1.

[0026] Reference Figure 1-3 Described, the inner side of control outer tube 8 near the bottom position is movably sleeved with extrusion rod 9, the bottom of extrusion rod 9 is fixedly connected with second connecting rod 10, the bottom of second connecting rod 10 is movably sleeved with fixing buckle 11, the outer surface of extrusion rod 9 near the inside of control outer tube 8 is provided with second spring 15, the bottom of second spring 15 is provided with buffer rubber pad 14, the buffer rubber pad 14 is provided with, can improve buffering effect, ensure the stability when using by the user, the buffer rubber pad 14 is movably sleeved with the inner side of control outer tube 8.

[0027] In the utility model, when in use, the user can pass the climbing rope through the inner side of the clamping block 4 and the main frame 1, and then connect the fixing buckle 11 with the safety rope worn by the user, and then the climbing rope can be used normally. In case of an unexpected situation, the first anti-slip pattern 12 and the second anti-slip pattern 19 will increase the friction, so that the control rod 3 slides to the side close to the first anti-slip pattern 12. By setting the adjustment slot 2, the control rod 3 squeezes the clamping block 4, and the clamping block 4 continuously increases the friction of the equipment through the first anti-slip pattern 12 and the second anti-slip pattern 19 on the main frame 1. In this way, the position is fixed, which protects the user. At the same time, when sliding down, the squeezing rod 9 will be pulled, and the squeezing rod 9 will squeeze the second spring 15. Then, the buffering rubber pad 14 will have a buffering effect on the user, which can protect the user from the impact force of sliding down.
