Abstract
The utility model relates to a fast fang bolt, which comprises a bolt shank 1 and a nut 2, wherein the front end of the bolt shank 1 is equipped with a slot, the nut 2 takes the shape of a cylinder, a taper stand 6 is mounted on the bottom of the cylinder, a circle of convex ring 5 is mounted on the inner wall of the nut 2 near the conical tip of the taper stand. The inner and the outer surfaces of the slot on the front end of the bolt shank 1 are equipped with a reversed gear 3, and the taper surface is equipped with a sequence gear 4. When the utility model is in service, the bolt shank is inserted in the nut and then the bolt shank is squeezed up emphatically, thereby the slot is squeezed and opened by the taper stand and fastened by the convex ring, which is capable of finishing connection quickly.
Description
Technical field
The utility model relates to coupling bar, particularly a kind of quick crab-bolt.
Background technique
At present, commercially available various coupling bars comprise various setscrews, it is by screw rod, expansion sleeve, packing ring and nut are formed, the hypomere of expansion sleeve is provided with latasuture, and the upper end of screw rod is provided with screw thread, and the lower end is gradually thick and be cone table, the threaded end of screw rod passes expansion sleeve and is connected with the nut of expansion sleeve upper end, rotating nut pulling screw rod makes the cone table of screw rod lower end move extruding in expansion sleeve, expansion sleeve then along latasuture open and with the hole wall chucking of placing sleeve pipe, trouble is used in this connecting means, and screw rod is overhanging, inadequately safety.
Summary of the invention
The purpose of this utility model is to provide a kind of quick connection crab-bolt.
The purpose of this utility model is finished by following technological scheme: it comprises tightening latch 1, bolt mother 2, it is characterized in that: tightening latch 1 front end cracks, bolt female 2 is a cylindrical shape, and the cylinder bottom is provided with circular cone 6, and the cone tip part near circular cone on the female inner tube wall of bolt is provided with a circle bulge loop 5.The two sides is provided with pawl 3 inside and outside tightening latch 1 front end cracks bar, establishes along tooth 4 at circular cone 6 conical surfaces.Tightening latch 1 is provided with a spacing block set 7, and corresponding site is provided with a depression that matches with projection 7 on the bolt mother 2.
The utility model need only insert tightening latch the bolt mother when using, jam-packed firmly, the bar that cracks of tightening latch front end will be squeezed by circular cone to be opened and is tightened by bulge loop, adds pawl that the bar that cracks is provided with and the suitable tooth on the circular cone and is meshing with each other, and can make crab-bolt can finish connection fast.
