Detailed ways

Example

Fig. 1 is a schematic diagram of an embodiment of the high-altitude safety rope self-locking device of the present invention, Fig. 2 is a schematic diagram of the internal structure of an embodiment of the high-altitude safety rope self-locking device of the present invention, and Fig. 3 is the implementation of the high-altitude safety rope self-locking device of the present invention. Figure 4 is a schematic diagram of the main casing of the embodiment of the high-altitude safety rope auto-locking device of the present invention. As shown in the figure, the utility model provides a high-altitude safety rope self-locking device, which includes a main casing 1, a rope groove 2 arranged on one side of the main casing 1, and a self-locking mechanism arranged in the main casing 1, The main casing 1 has a one-piece structure and includes a front casing 101 and a rear casing 102. The rope groove 2 includes an upper rope groove 201 and a lower rope groove 202. One side of the front casing 101 and one side of the rear casing 102 Fixed connection, the upper rope slot 201 is arranged on the upper end of the other side of the rear casing 102, and the lower rope slot 202 is arranged at the lower end of the other side of the front casing 101. The high-altitude safety rope self-locking device has high strength, light weight and easy to carry. The advantages.

The self-locking mechanism includes a blocking member 3 and a blocking sheet 4. The bottom end of the blocking member 3 is provided with a connecting hole 5. The blocking member 3 is provided on the side of the main casing 1 away from the rope groove 2, and the blocking sheet 4 is provided on the rope groove. 2 and the blocking member 3, a number of evenly distributed teeth 11 are arranged on the side of the blocking sheet 4 close to the rope groove 2. The neat teeth 11 can provide better gripping force, without any inverted teeth, reducing the risk of friction. If the rope is damaged, the contact surface of the blocking piece 3 and the blocking piece 4 is set as an inclined surface 6, and the inclined surface 6 is inclined from the blocking piece 4 to the blocking piece 3.
