Novel nut with constant torsion for bolt

Abstract

The invention belongs to the field of fasteners, and especially relates to a novel nut structure with constant torsion used when the bolt is locked. The novel nut with constant torsion for a bolt includes a sleeve and a torsion ring sleeve. The torsion ring sleeve is arranged on the bottom of the sleeve. The novel nut with constant torsion is also provided with a torsion rod. The sleeve passes through the torsion rod. The outer circumference of the sleeve is a polygon and the inner circumference is a circular structure. The torsion rod is prepared by a metal material or a fiber reinforced plastic material. The surface of the torsion rod is provided with threads, and so the grasping is convenient. The novel nut with constant torsion also includes a torsion wrench. The torsion wrench is arranged on the top of the sleeve. The connection of the torsion wrench and the top of the sleeve is a threaded connection. The pulling of the nut with constant torsion can be more laborsaving by using the lever principle. With the double help of the torsion rod and the torsion wrench, the tightening or loosening of a screw rod are more laborsaving. Furthermore, the damage quantity of the nut with constant torsion is reduced and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fasteners, in particular to a novel nut structure capable of constant torsion when an anchor rod is locked. Background technique [0002] Anchor rods (such as FRP anchor rods or steel anchor rods, which are described below with FRP anchor rods as examples) are generally used to provide support functions. In the field of use, FRP nuts are mostly locked manually when locked, but in construction At present, it is difficult to manually grasp the torsion state of the fiberglass anchor rod when the body is locked. If the torsion is small, the pulling force of the rod is not enough, and if the torsion is too large, the body will be easily damaged. During construction, to control the torsion of the FRP anchor, a torque wrench is generally used, but the work efficiency is very low; some people add a torsion device at the end of the nut to control the torsion, but when the tensile force of the anchor body is not up to the re...

[0002] Anchor rods (such as FRP anchor rods or steel anchor rods, which are described below with FRP anchor rods as examples) are generally used to provide support functions. In the field of use, FRP nuts are mostly locked manually when locked, but in construction At present, it is difficult to manually grasp the torsion state of the fiberglass anchor rod when the body is locked. If the torsion is small, the pulling force of the rod is not enough, and if the torsion is too large, the body will be easily damaged.

During construction, to control the torsion of the FRP anchor, a torque wrench is generally used, but the work efficiency is very low; some people add a torsion device at the end of the nut to control the torsion, but when the tensile force of the anchor body is not up to the requirement It is possible to touch the torsion device, or when the nut is locked, the tail of the rod body has not touched the torsion device, so that it cannot play the role of stabilizing the torsion force on the rod body while the anchor rod is locked.
