Description

Technical Field

[0001] The utility model relates to the technical field of screw sleeves, in particular to a track screw sleeve that can be quickly installed and fixed. Background Art

[0002] The threaded sleeve is a new type of internal thread fastener, suitable for threaded connection. It is screwed into and fastened into the threaded hole of one of the connected parts to form a standard internal thread, into which the bolt is then screwed. It has the functions of high connection strength, vibration resistance, impact resistance and wear resistance.

[0003] Tracks are mainly composed of rails, sleepers, roadbeds, switches, connecting parts, etc., among which the connecting parts can connect the rails and sleepers, including fasteners, rail clamps, track clamps, etc. The rail clamps can fix the rails on top of the sleepers, and usually require bolts and the internal threaded holes of the rail clamps for movable connection. However, as the use time increases, the internal threads of the rail clamps will be damaged, which will make the rail clamp unable to be fixed. The usual practice is to replace the rail clamps with new ones, but this method requires the rails to be removed before it can be carried out, so the maintenance of the internal threads of the rail clamps is very troublesome.
