Abstract
The utility model relates to a loosing-proof maintenance-free fixed bolt, which can prevent a bolt from being loosened in using. The utility model is composed of a threaded rod 3, a threaded cap 2 and a threaded post 1, and the threaded post 1 can be a taper threaded post. A threaded hole 5 is arranged on the threaded end surface of the threaded rod 3, and symmetrical expanded grooves 4 are arranged on the hole wall of the threaded hole 5. After a connected part is fastened by the threaded rod 3 and the threaded cap 2, the threaded cap 2 is locked on the threaded rod 3 and has no loose scope, and therefore, the loosing-proof maintenance-free fixed goal of the bolt is achieved. The utility model has the advantages os simple and reasonable structure, safe and convenient use, low cost, etc., and can be widely suitable for the connection and fixation field of the machinery of assembly, connection and fixation of an oil pumping machine, etc.
Description
The utility model relates to a kind of bolt, belongs to anti-loosening non-maintaining fixing bolt.
At present, mechanical connection is fixed used bolt both at home and abroad, form by threaded threaded stem and thread cap mostly, and after thread cap tightens, unnecessary threaded shank portion is in useless state, moment of torsion greatly, often is in the mechanical part under the high frequency motion state when fixedly connected work, the bolt looseness phenomenon that different situations will occur, fastening as untimely maintenance, also can cause unnecessary mechanical accident and economic loss, so prior art can't fundamentally satisfy people's safety in production needs.
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, and a kind of anti-loosening non-maintaining fixing bolt of security insurance is provided.
The purpose of this utility model can reach by the following technical programs: fixing bolt is made up of threaded stem, thread cap and screw column.The utility model is to form tapped hole on the screw thread end face of threaded stem, forms the expansion slot of symmetry on the tapped hole hole wall, and be connected with screw column on this tapped hole.
The tapered thread post that on the screw thread end face of threaded stem, can form conical screw hole and match.After threaded stem is passed the parts that will connect, thread cap is screwed on the threaded stem tightens, reach the fastening connection piece purpose, then screw column is screwed in the tapped hole on the threaded stem and tightens, make the local locking mutually of screw thread between threaded stem and the thread cap, make thread cap not have loosening leeway, thereby reach the purpose of anti-loosening non-maintaining fixing bolt.
The utility model can have following advantage than above-mentioned prior art: this bolt can be when being connected and fixed work moment of torsion greatly, often be in the special bolt of high frequency moving mechanical part.It has simple and reasonable, and the installation replacing is convenient, flexible, cost is low, can guarantee the absolute fastening safety of manufacturing machine in the using process, and is widely used in various mechanical fixation connection needs.
Fig. 1 is a whole-cutaway view of the present utility model;
Fig. 2 is that the master of threaded stem 3 on Fig. 1 looks whole-cutaway view;
Fig. 3 is the plan view of threaded stem 3 on Fig. 2;
To be described further the utility model below in conjunction with accompanying drawing:
In conjunction with shown in 2,3, on the screw thread end face of threaded stem 3, form tapped hole 5 by Fig. 1, can form the expansion slot 4 of symmetry on tapped hole 5 hole walls.Be fastenedly connected the parts purpose for reaching, on threaded stem 3, be connected with thread cap 2; For reaching anti-loosening non-maintaining purpose, on threaded stem 3, be connected with the screw column 1 that cooperates with it in the tapped hole 5 of screw thread end face.
Assembling using process: at first threaded stem 3 is passed the parts that will connect, again thread cap 2 is screwed on the threaded stem 3 and tightens, then screw column 1 is screwed in the tapped hole 5 on the threaded stem 3 and tightens, make the local locking mutually of screw thread between threaded stem 3 and the thread cap 2, make thread cap 2 not have loosening leeway, thereby reach the purpose of anti-loosening non-maintaining fixing bolt.
Claims (3)
1, a kind of anti-loosening non-maintaining fixing bolt, it has threaded stem (3), thread cap (2), it is characterized in that: a forms tapped hole (5) on threaded stem (3) screw thread end face, forms the expansion slot (4) of symmetry on tapped hole (5) hole wall, and screw in screw column (1) on this tapped hole.
