Abstract
The utility model discloses an expansion bolt convenient to install. A cuboid or a cylindrical dummy club is added at the tail end of the bolt, a nut can be conveniently screwed down by clamping the dummy club of the bolt with a tool during installation, and threads of the bolt can not be damaged, so that the purpose of installation is achieved. A shaft neck is added at the root of the dummy club, and when the dummy club is required to be removed after the installation of the expansion bolt, the dummy club can be knocked with a tool to ensure that the dummy club is broken from the position of the shaft neck.
Description
Affiliated technical field
The utility model relates to a kind of EXPANSION ANCHOR BOLTS, especially is convenient to the EXPANSION ANCHOR BOLTS of installing.
Background technique
At present, known EXPANSION ANCHOR BOLTS structure is made up of bolt, expansion tube, plain washer, bullet packing ring and nut.Put into mounting hole after during installation all parts being installed in order, the nut of screwing then is fixing after with the expansion tube swelling.But because bolt has only the inconvenient clamping that is exposed of a bit of screw thread, bolt is prone to rotation and is difficult for tightening when screwing nut, also is prone to crush the screw thread of bolt during clamping screw.
Summary of the invention
In order to overcome the inconvenient clamping of traditional expansion bolt and to screw, increase the boss of a clamping at the bolt tail end.With the boss of instrument clamping bolt fastening nut easily.
The utility model solves the technological scheme that its technical problem adopted: increase cuboid or cylindrical boss at the bolt tail end; During installation with the boss of instrument clamping bolt fastening nut easily; Can not crush the screw thread of bolt yet, reach the purpose of being convenient to install.Increase an axle journal at the boss root, in the time of after EXPANSION ANCHOR BOLTS is installed, need removing boss, tool is knocked boss makes it rupture from axle journal.
The beneficial effect of the utility model is to make the installation of EXPANSION ANCHOR BOLTS become convenient, simple in structure.
