Specific embodiment
With reference to the accompanying drawings, the utility model is further described below.
The utility model discloses a kind of novel high corrosion resistant anchor bolts, are different from the prior art and are：Including a screw rod 1,
One end of screw rod 1 forms cone head part 2, and screw rod 1 forms one section of external screw thread 3,1 other end of screw rod on the screw rod outer wall of the other end
End form striking head 4, the friction plate 5 of a cyclic structure is socketed on the screw rod 1 of the inside of cone head part 2, in 1 other end of screw rod
Nut 6, spring washer 7, plain washer 8 are disposed at the external screw thread 3 of side, is formed on the bar wall of the screw rod 1 of 5 inside of friction plate
The cyclic annular limiting section 9 of protrusion, the whole structure annular in shape of friction plate 5, the shape on the edge of 2 one end of cone head part of friction plate 5
Into the vee 10 of three equidistantly distributeds, two apex angles of vee 10 are respectively positioned on the edge of 5 one end of friction plate
On, 10 inside vertex of vee extends to form cutting line 11 inwardly, and three cutting lines 11 are by friction plate 5 close to conehead
One section of trisection in portion 2 offers semicircle orifice 12 at the friction plate 4 of the inside of cutting line 11, which connects with cutting line 11
Logical, 5 outer wall of friction plate between two neighboring vee 10 is equipped with the anti-skidding muscle 13 of three parallel distributions, and three anti-skidding
The length of muscle 13 is incremented by successively, and the anti-skidding muscle 13 of this close to 5 one end of friction plate is shorter, and the height of three anti-skidding muscle 13 is passed successively
Increase, the anti-skidding muscle 13 of this close to 5 one end of friction plate is relatively low, is formed on 5 outer wall of friction plate of above-mentioned three anti-skidding 13 insides of muscle
