Description
Technical field
The present invention relates to a kind of bolts, and be especially provided with fixed pin is auxiliarily fixed type bolt, is suitable for one-handed performance.
Background technology
In equipment and the device installation of a variety of frame structures, need to connect connector by bolt.Such as electricity
The installation of power steel tower is exactly to be attached using bolt by angle steel or channel steel.In general, during installation, connector is worn
After upper screw bolt and nut, one end fixes rotating nuts by spanner or nut, the other end are fastened by Wrench, needs
Both hands operate or two people operate.This situation one side labor intensive, on the other hand, this danger on power tower
Work places, both hands operation it is abnormally dangerous.Therefore, how to realize that bolt can be fixed during the installation process, avoid installation process
Middle both hands or more people operation, prevent screw rod when tightening nut from rotating therewith, improving operating efficiency, are that the technology solved is needed to ask
Topic.
Invention content
For the above technology demand, the present invention provides one kind and type bolt is auxiliarily fixed, and being arranged on screw rod can assist it to fix
Fixed pin so that after connector puts on bolt, bolt can be fixed in screw hole, and operating personnel singlehanded can grasp when tightening nut
Make, increases processing safety and convenience.
To reach above-mentioned technique effect, the present invention provides the following technical solutions：
Type bolt is auxiliarily fixed in one kind, its fixed fixed pin can be assisted by having on bolt.
By the active force between fixed pin and screw hole in operation process, bolt is fixed in screw hole, when screw on nut, spiral shell
Bar will not rotate, and reach the singlehanded operable effect of operating personnel, also, bolt also can be taken off reusing.
The fixed pin is the protrusion of screw rod outer surface.
After fixed pin is arranged in screw rod, outer diameter should be almost the same with screw hole, and outer diameter is usually no more than outside the nut of bolt
Diameter.After bolt is inserted into screw hole, screw hole inner wall is contacted at the top of fixed pin, generate frictional force and minute elastic deformation occurs, and blocks spiral shell
Bolt, to have the function that bolt and screw hole relative position are constant.
Preferably, the fixed pin is prismatic or the protrusion of prism-frustum-shaped.
Fixed pin is inserted into bolt in screw hole, during initial tightening nut, part that fixed pin is contacted with screw hole
Certain elastic deformation occurs, screw rod and screw hole is made rigid contact and to prevent displacement under stress.Fixed pin is set
It is set to prismatic or the protrusion of prism-frustum-shaped, it is therefore intended that on the one hand increase the contact area of fixed pin and screw hole, increase frictional force；Separately
On the one hand, increase fixed pin itself for the tolerances of friction stree, avoid being caused in operation for fixed pin itself
Damage so that losing its fixed effect.
Preferably, the fixed pin is provided with inclined-plane along screw rod direction of insertion.
Under normal conditions, to reach bolt and generate enough frictional force, outer screw diameter (adding fixed pin) Ying Ji with screw hole
This, which coincide, is even slightly larger than screw hole internal diameter, is inserted into screw hole for convenience of bolt, fixed pin is provided with inclined-plane along screw rod direction of insertion.
Preferably, the inclined-plane is wedge shape.
Wedge shape inclined-plane be more convenient for bolt be inserted into screw hole.
Preferably, the fixed pin quantity is 3,120 ° of interval is uniformly distributed.
To increase the fixed effect of bolt and screw hole, fixed pin is preferably uniformly distributed in screw surface, prevents bolt from sending out
It is raw eccentric.
Fixed pin and screw rod are connected with various ways, including：The fixed pin is fixed on screw surface.
Fixed pin can be fixed on screw surface by welding manner, can also the one-pass molding when making bolt.
The fixed pin is independently of bolt.
Fixed pin can simplify process independently of bolt to avoid the technique of fixed pin is prepared on screw rod, and when use directly will
Independent fixed pin is assemblied in screw surface, is inserted into together with bolt in screw hole fixed.
Preferably, the fixed pin independently of bolt is closure or tubular structure jaggy.
Fixed pin may be used monoblock steel plate punched at the matched tubular structure of screw rod, tubular structure is set with by when use
In screw rod.
When fixed pin uses tubular structure, three protrusions are preferably provided with, tubular structure may exist notch, not necessarily by spiral shell
Bar all coats.
In addition, sliding slot can be also set on screw rod, and fixed pin setting and the matched protrusion of sliding slot (sliding block), as needed
Fixed pin is disposed on toward bolt.
Sliding slot specification can be unified, and fixed pin ontology can make different sizes, since sliding slot is general when use, Ke Yigeng
Easily select the fixed pin of different height and specification.
The fixed pin material is magnetic material.
Fixed pin is manufactured using magnetic material, is adsorbed on connected workpiece by the adsorption capacity of magnet, can be increased and spiral shell
The stress of bolt and screw hole, it is further provided function is auxiliarily fixed.
Of the present invention that type bolt is auxiliarily fixed, reasonable design is simple in structure, after bolt passes through connector screw hole, spiral shell
Bolt can be fixed in screw hole, operating personnel's one-hand operation when tightening nut, increase processing safety and convenience, particularly suitable
In the hazardous environments operation such as high-altitude.
