Description

Fastener is used in track construction easy to assemble

Technical Field

The invention relates to the technical field of track construction, in particular to a fastening device for track construction, which is convenient to install.

Background

Bolt, nut type fasteners, when the nut is tightened with a torque force, the tendency of the bolt to follow the nut in turn, and the reaction force of the torque force exerted by the torque power tool on a nearby stationary object causes a side load on the fastener to be tightened; the friction between the bolt and the nut threads has a tendency to pull on the bolt, which has not yet been firmly connected, where the nut is subjected to a twisting force; in other words, the rotational friction force on the screw thread caused by the nut to be turned is often greater than the rotational friction force of the counter-nut attached to the screw on the other side of the part to be attached, despite the frictional force on the face to which the rotating counter-nut is subjected; even if there is a washer under the nut to be turned, it can be dragged as the nut is turned; there is also a tendency for a bolt to rotate as it is threaded into a blind hole in the bottom of the parts to be joined. For these reasons, industry often uses a support wrench to stop the bottom nut from following rotation or an L-hex wrench inserted into the socket on top of the blind stud to hold the stud so that it no longer rotates within the threaded blind hole. This measure is not always effective, since the holding force must be changed in response to the high torque requirements of the crack in the bolt thread when the crack occurs.

When the prior fastening device is used for fixing, the bolt can loosen automatically in the vibration process, so that the fixing piece can be loosened, the fixing effect can be influenced, and the engineering quality can be influenced; most of the existing fixing devices need complex operation and multiple tools during fixing, and the design is not easy to use during installation, so that the working efficiency is reduced; still other fastening devices are not easily balanced when securing objects with uneven surfaces, which affects the stability of the fixation.
