The embodiment of the present application provides a fastening anchor, please refer to fig. 1-5: the anti-skidding type steel wire rope clamp comprises a drilling hole 1 and a main rod 2, wherein threads 3 are arranged on the side surface of the main rod 2, a nut 4, a spring gasket 5 and a flat pad 6 are installed at one end of the main rod 2, a circular truncated cone-shaped bulge 7 is arranged at the other end of the main rod 2, a first lantern ring 8 is installed on the side surface of the main rod 2, an anti-skidding assembly is arranged at the lower end of the first lantern ring 8, a second lantern ring 9 is installed at the lower end of the anti-skidding assembly, the second lantern ring 9 is integrally formed, and a special-shaped opening 10 is formed in the side surface of the second lantern ring 9;

the anti-skidding assembly comprises a nylon ring 11 and an anti-skidding part, a trapezoidal protrusion 12 is installed at one end of the second lantern ring 9, a trapezoidal opening 13 is formed in one end of the nylon ring 11, the trapezoidal protrusion 12 is inserted into the trapezoidal opening 13, the nylon ring 11 is sleeved on the main rod 2, the nylon ring 11 is sleeved between the first lantern ring 8 and the second lantern ring 9, and the anti-skidding part is used for limiting the relative position of the drill hole 1 and the nylon ring 11.

In practical application, before use, a proper drill hole 1 is drilled, and the main rod 2, the nut 4, the spring washer 5, the flat gasket 6, the first lantern ring 8, the second lantern ring 9 and the nylon ring 11 are assembled together, as shown in fig. 1; under the action of the special-shaped gap 10, when the circular truncated cone-shaped bulge 7 extrudes the second lantern ring 9, the second lantern ring 9 is convenient to expand and deform; the friction force between the nylon ring 11 and the drill hole 1 can be enhanced through the function of the antiskid part, and the nylon ring 11 is prevented from rotating;

after mobile jib 2 is pounded into drilling 1 in, the manual work is held corresponding spanner and is twisted nut 4, through the precession of nut 4, dwindles between the distance between nut 4 and the protruding 7 of round platform shape, through the effect of lantern ring 8, the transmission of nylon ring 11, the protruding 7 of round platform shape is to the position extrusion of two 9 special-shaped openings of lantern ring 10, the intensity of the 10 son of special-shaped opening this moment, the position expansion of two 9 lower extremes of lantern ring to both sides to prop up drilling 1, thereby produce the anchor power.

Referring to the attached drawings 1 and 3, the antiskid part comprises a triangular protrusion 14 arranged on the annular side surface of the nylon ring 11, a trapezoidal protrusion 15 is arranged on the annular side surface of the nylon ring 11, the triangular protrusion 14 and the trapezoidal protrusion 15 are arranged in a plurality of annular arrangements, and the triangular protrusion 14 and the trapezoidal protrusion 15 are respectively arranged at two ends of the nylon ring 11.

In practical application, the distance from the top end of the triangular protrusion 14 to the axis of the main rod 2 is greater than the distance from the top end of the trapezoidal lug to the axis of the main rod 2, and when the main rod 2 moves in the drilled hole 1 and the diameter of the drilled hole 1 is larger, the triangular protrusion 14 can contact the side wall of the drilled hole 1, so that the purpose of increasing friction force is achieved; when the diameter of the drill hole 1 is smaller, the side wall of the drill hole 1 can grind the tip of the triangular protrusion 14 flat, and the nylon ring 11 has a more stable state through the combined action of the triangular protrusion 14 and the trapezoidal bump 15;

when the nut 4 is screwed by holding a corresponding wrench manually, the main rod 2, the circular truncated cone-shaped bulge 7 and the second lantern ring 9 tend to rotate, but when the nylon ring 11 is in a stable state, the second lantern ring 9 can be prevented from rotating under the action of the trapezoidal bulge 12 and the trapezoidal opening 13, the second lantern ring 7 is extruded by the circular truncated cone-shaped bulge 7, large friction force is generated between the second lantern ring 9 and the circular truncated cone-shaped bulge 7, the circular truncated cone-shaped bulge 7 and the main rod 2 are also in a stable state, and the main rod 2 and the nut 4 are prevented from rotating in a shaft connecting mode.

Referring to the accompanying

drawings

1, 2 and 3, the connecting line of the triangular projection 14 and the trapezoidal projection 15 is inclined to the axis of the main rod 2.

In practical application, the nylon ring 11 is stressed more evenly by the staggered arrangement of the triangular protrusions 14 and the trapezoidal bumps 15.

The main rod 2 is also provided with a positioning part.

Referring to the attached figures 1, 2 and 3 of the specification, the positioning part comprises a butterfly-shaped bulge 16 arranged on the side surface of the truncated cone-shaped bulge 7, and the butterfly-shaped bulge 16 is positioned in the special-shaped gap 10.

In practical application, the butterfly-shaped protrusion 16 is arranged at the position of the special-shaped notch 10, so that the circular truncated cone-shaped protrusion 7 and the second lantern ring 9 can be prevented from moving relatively, and the phenomenon of shaft connection rotation can be avoided to the maximum extent, but the structure causes the increase of the processing cost of the circular truncated cone-shaped protrusion 7.

Referring to the accompanying

drawings

1, 2 and 3, the positioning part comprises a key slot 17 formed on the side surface of the primary rod 2, a key block 18 is mounted on the inner ring of the nylon ring 11, the key block 18 is slidably connected with the key slot 17, and the butterfly-shaped protrusion 16 can be made by stamping.

In practical application, the relative rotation between the nylon ring 11 and the main rod 2 can be avoided by the structural characteristics of the key groove 17 and the key block 18, but the structural strength is low.
