Abstract

The invention provides a guardrail steel cable quick locking device which is used for being installed on the portion, close to the end of a steel cable, of the steel cable and detachably fixed to a guardrail. The locking device comprises an outer sleeve, a conical chuck, an elastic component and an installing and fixing mechanism, wherein the outer sleeve is provided with a conical through hole and a first internal thread hole which are communicated with each other, and the hole diameter of the first internal thread hole is larger than or equal to the largest hole diameter of the conical through hole. The conical chuck is provided with a clamping hole used for the steel cable to pass, a plurality of clamping teeth are arranged in the clamping hole, and the conical chuck is placed in the conical through hole of the outer sleeve. The elastic component is placed at the bottom of the conical chuck in the outer sleeve. The installing and fixing mechanism is fixedly installed on the guardrail and provided with a first external threaded rod, the first external threaded rod is combined with the first internal thread hole in a screwed mode, and the elastic component is placed at the end of the first external threaded rod. The guardrail steel cable quick locking device can be installed upwards and downwards by 0-90 degrees, and the steel cable can freely rotate by 360 degrees. The guardrail steel cable quick locking device is enough in locking force, not prone to loosening after bearing external force, wide in applicability, convenient to install and high in work efficiency.

Description

technical field [0001] The invention relates to the technical field of guardrail protection products, in particular to a quick locking device for guardrail steel cables. Background technique [0002] The steel cable is used for the invisible installation of the home or the installation between the outdoor guardrail posts, and the cable tensioning device is required. The patent number is: US7198253, the U.S. patent that the title is called: WIRE ROPE CONNECTORS AND TENSIONERS FOR DECK RAILING SYSTEMS discloses a kind of guardrail cable tensioning device, and this guardrail steel cable tensioning device has the following disadvantages: 1. Locking force Not enough, it is easy to loosen under a little external force, and the maintenance cost is high; 2. The installation time is long, the labor cost is high, and the work efficiency is low; 3. The installation angle is only 0 to 45 degrees, and the environmental applicability is insufficient. [0003] In view of this, the present...
