In No. 200920215856th, Chinese utility model patent, a kind of high-strength fastening bolt is disclosed, its body of rod cross-sectional outer diameter is equal with the width of T-shape head, higher in the joint intensity of T-shape head and the body of rod, be not easy to make because of External Force Acting to rupture between T-shape head and the body of rod, adopt necking down bar to reduce quality and the volume of bolt to a certain extent, and do not affect the bulk strength of bolt.In No. 200520025360th, Chinese utility model patent, a kind of Self-locking fasterning bolt is disclosed, it comprises one end and is formed with the externally threaded bolt of certain length and nut, the other end of bolt is formed with the opening slot that profile of tooth hook long end can be concealed in groove, that moves cooperation in the end of opening slot by fixing pin fixedly has certain length, its width is slightly less than the diameter of bolt, and both sides form serrate profile of tooth hook.The existing clamping bolt that these two patents disclose all need from two-sided carry out fastening, be not therefore suitable for limited location need carry out fastening specific use occasion from the monolateral of fastening piece.
Summary of the invention
The purpose of this utility model is to provide the fastening self-expansion type fastening bolt device of a kind of one side, can realize carrying out tightening operation from fastening piece one side and have again and two-sided fastening equal fastening effect.
The fastening self-expansion type fastening bolt device of one side of the present utility model, for being fastenedly connected of 2 fasteners, the fastening self-expansion type fastening bolt device of this one side comprises sleeve, bolt, four threads, wherein said bolt is hexagonal screw rod, described sleeve putting is in the endoporus of described 2 fasteners, described sleeve inner is formed with four draw-in grooves be arranged symmetrically with, for being connected cooperation with described four threads, each described thread is hexagonal column structure, its side direction is processed with screw thread, for being connected cooperation with described bolt.
Described bolt comprises hexagon-head and the threaded screw rod of tool, each thread comprises long columnar part at a right angle and short columnar part, the shape in the cross section of described long column body is identical with the sectional shape of draw-in groove, the side direction that its middle long column body divides forms described screw thread, after the long column body of described screw rod and described four threads splits the inside putting described sleeve into, each long columnar part is embedded described draw-in groove and is engaged with described screw flight by described screw thread.
The sectional shape of described draw-in groove and cylinder is hexagon.
Described sleeve, bolt and thread all adopt high-strength steel to make.
Described thread has magnetic.
The utility model realizes self-expanding by the optimum organization of the magnetic thread of sleeve, screw rod and band under the connection of screw thread, thus it is fastening to realize fastening piece one side; By screw rod and circumference being threaded of four threads, make can realize two-sided fastening fastening effect by one side secured mode; In assembling, significantly reduce the difficulty of assembling with magnetic thread, locate simply, be easy to operation, applicability is strong.
