Description
Technical Field
The utility model relates to a steel construction bolt especially relates to a steel construction bolt convenient to dismouting.
Background
The steel structure bolt is a high-strength bolt and is also one of standard parts. The fastening performance is better, is used for the steel construction, on the engineering, makes the fastening effect. The steel construction bolt is at the fastening and dismantlement in-process, and the nut needs the round circle rotatory, and is longer at rotatory in-process time, makes the bolt dismantle very inconvenient, and the bolt is when producing the shock moreover, and the nut drops easily, makes the overall structure of bolt unstable inadequately.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a steel construction bolt convenient to dismouting to solve above-mentioned technical problem.
In order to realize the purpose, the utility model adopts the following technical scheme:
the utility model provides a steel construction bolt convenient to dismouting, includes base, cylinder, external screw thread, the tight groove that rises, spout, retaining ring, the tight strip that rises, nut, internal thread piece, the base is the hexagon structure, base top surface center vertical fixation has the cylinder, open on cylinder upper portion has the external screw thread, open the tight groove that rises that has numerical direction in cylinder top center, open the cylinder top has the spout of a plurality of angle partitions, the retaining ring cup joints in the cylinder outer wall, the retaining ring inner circle is fixed with the tight strip that rises, the nut is connected in the cylinder outer wall, nut inner circle circumference angle partition has a plurality of internal thread pieces.
On the basis of the technical scheme, the tensioning strips are in isosceles trapezoid structures with wide upper parts and narrow lower parts, the tensioning strips are connected in a sliding mode up and down along the tensioning grooves, and the width of the tops of the tensioning strips is larger than that of the tensioning grooves.
On the basis of the technical scheme, the internal thread block is connected with the external thread in a threaded manner along the sliding groove in a vertically sliding manner.
On the basis of the technical scheme, the bolt is made of low-carbon alloy steel, and the surface of the bolt is subjected to blackening, oxidation, phosphorization, blackening and other treatments.
Compared with the prior art, the utility model has the advantages of it is following: the utility model discloses the internal thread piece of nut can follow spout high-speed slip and carry out screw-thread fit to the fastening point, has saved the tightening efficiency of nut, and the tight strip that rises of retaining ring can produce elastic deformation to the cylinder that opens there is the tight groove that rises, makes the nut hugged closely more to the external screw thread, and the increase makes the difficult pine of nut take off.
