Description
Technical field
The utility model relates to the improved type bolt that a kind of fastening standard piece is used.
Background technique
Bolt, mechanical parts, the cylindrical threaded fastening piece of adapted nut.Bolt: by head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole.This Connecting format claims bolt to connect.As nut is screwed off from bolt, can make again these two parts separately, be to belong to removably connect therefore bolt connects.
But connect occasion in part, between two connected pieces of its bolton, need long-time fixing, the chance of dismounting is less, therefore, for fear of nut loosening, conventionally need to, welding solder joint between nut and bolt, avoid like this nut loosening, but this class formation be when needs be dismantled two connected pieces, comparatively trouble, need butt welding point to melt, the trouble of bringing to operation, is therefore not suitable for promoting the use of.
Summary of the invention
The technical problems to be solved in the utility model is to provide the improved type bolt that a kind of fastening standard piece is used, and this device can prevent nut loosening preferably, ensures fixedly, simultaneously for convenience fastening, and more for convenience, recycling rate of waterused is higher, avoids waste in dismounting.
For addressing the above problem, the utility model adopts following technological scheme:
The improved type bolt that a kind of fastening standard piece is used, comprise screw head, screw rod and nut, described screw head and screw rod are integral type, described nut sleeve is located on screw rod, described screw rod has a smooth end face away from one end of screw head, this end face Yan Bianchu has chamfering, on the end face of described screw rod, offer a criss-cross catching groove, described nut top is provided with four steel bars, described steel bar is looped around screw rod four sides, between four steel bars, be combined with the fastener of a ring, described fastener middle part has a button piece interlocking with described catching groove, described screw rod has a smooth department near the position of screw head, on this smooth department, be arranged with packing ring, the circumferencial direction of described packing ring is provided with a breach, the width of breach is greater than screw diameter.
As preferred technological scheme, the thickness of described packing ring is not more than the pitch of the screw thread on screw rod outer ring.
As preferred technological scheme, the structure that described steel bar and nut are casting integrated formula.
As preferred technological scheme, described screw head and nut all have a hexagonal outer surface.
As preferred technological scheme, the top of described fastener offers the hole of passing for steel bar, and described hole is rectangular opening.
The beneficial effects of the utility model are: when use, first screw sleeve is located between two connected pieces, then rotating nut, nut and connected piece are offseted, then fastener is set on steel bar, the middle button piece of fastener is matched with catching groove, then bend steel bar, avoid loosening, after bending, if exist loosening between two connected pieces, packing ring can be beaten on screw rod, realize fastening, this device can prevent nut loosening preferably, ensure fixed, simultaneously for convenience fastening, dismounting more for convenience, recycling rate of waterused is higher, avoid waste.
