Description
The utility model is a kind of lock bolt, is a kind of mechanical fastener.
Existing lock bolt kind is more, as: EXPANSION ANCHOR BOLTS etc.; Chinese patent communique 20249293 discloses a kind of " tapered cup nut EXPANSION ANCHOR BOLTS ", and this bolt arrangement is reasonable, and fixing is effective; But also there is a problem in it, exactly: could be with use, so the program of using is a more complicated after it is formed, these three parts will be installed when using by three parts.
The purpose of this utility model is to invent a kind of lock bolt, to overcome the existing in prior technology problem.
The utility model is to constitute like this: it has a screw rod 1, it also has a locking pipe box 2, one end of locking pipe box 2 has screw thread 3, screw thread 3 matches with screw thread 4 on the screw rod 1, the other end of locking pipe box 2 has two roads above locking slot 5 and the locking-blade more than two 6, and locking-blade 6 is V-shaped barb 7.
Accompanying drawing 1 is a structural representation of the present utility model, and accompanying drawing 2 is structural representations of locking pipe box 2 of the present utility model, and accompanying drawing 3 is side views of locking pipe box 2.
Embodiment of the present utility model: make a screwed screw rod and a screwed locking pipe box earlier, the screw thread of screw rod and locking pipe box cooperatively interacts, one end of locking pipe box is made three road locking slots and three locking blades, and locking-blade is V-shaped barb.During use, screw rod is screwed in the locking pipe box, on metope, bore a hole, in this bolt-inserting hole, then, rotary screw, at this moment, locking pipe box spreading, V-shaped locking-blade be spreading and barb is inserted in the metope also, so promptly reaches fixing purpose.The utility model is simple in structure, easy to use, be easy to make.
