Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high strength hinged bolt, to solve the problem proposed in above-mentioned background technology.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of high strength hinged bolt, comprise screw rod and bolt head, the surface lower portions of described screw rod evenly leaves screw thread, the first groove is left in the upper surface of described screw rod, the upper surface of described screw rod leaves the second groove, in the middle part of the inner surface of described bolt head and edge is respectively equipped with first protruding and the second projection, described first protruding and the second protruding movable embedding company second groove and the first groove respectively, the bottom margin of described bolt head is provided with packing ring.
Preferably, the top surface edge of described screw rod leaves the first anti-slip veins, and the lower surface edge of described packing ring leaves the second anti-slip veins.
Preferably, the upper surface middle part vertical and horizontal of described bolt head are respectively equipped with the 3rd groove and the 4th groove, and the 3rd groove and the 4th groove are staggered to form a criss-cross groove.
Preferably, the length of described 3rd groove is the twice of the 4th groove.
Preferably, the bottom of described second projection and the lower surface joint of bolt head are provided with and bolt head and the second protruding integrated reinforced block.
Preferably, the described first protruding, the second projection, the first groove and the second groove quantity is all no less than four.
The invention has the beneficial effects as follows: high strength hinged bolt of the present invention, the while that the first groove that first protruding and the second male cooperation screw rod that bolt head is provided with is provided with and the second groove can making screw rod and bolt head realize dismountable, the adhesive strength of bolt head and screw rod also reaches very high level, be convenient for changing bolt head, the packing ring that bolt head lower edge is provided with eliminates the trouble of carrying pad in addition secretly, facility is brought to job site, structure is simple, convenient and practical, be suitable for large range promotion use.
