Abstract
The utility model discloses a double ratchet wheel straightening tightener, which comprises a shell, two ratchet wheels and a rotating shaft; wherein, the rotating shaft is arranged inside the shell, two ratchet wheels are arranged on both ends of the rotating shaft respectively, each ratchet wheel is matched with two pawls; the positioning pawl is movably fixed on the shell, the main transmission pawl is movably fixed on the shell by a pull rod, the pull rod can rotate on the shell; two positioning pawls on both ends of the rotating shaft are connected with each other by a positioning bar, a thread hole is arranged on the shell, a return spring is arranged on the positioning bar. The utility model has the advantages of simple structure, convenient operation with a person necessary, low working strength, high working efficiency, reliability by adopting double ratchet wheel structure, and being applicable to erection of electrical cable in department of power supple and optical cable in communication industry.
Description
Technical field
The utility model relates to a kind of pair of stretching wire grip of ratchet.
Background technology
In the cable of power supply department and the optical cable installation of the communications industry, cable, that optical cable will be drawn into is straight.At present, mostly adopt artificial traction to stretch, the number of workers requirement is many, labour intensity is big, and operating efficiency is very low.
Summary of the invention
The purpose of this utility model just provides a kind of stretching wire grip of two ratchets of simple in structure, easy to use, high efficiency.
The of the present utility model pair of stretching wire grip of ratchet comprises housing, ratchet, rotating shaft, rotating shaft is located in the housing, its two ends are fixed with ratchet respectively, each ratchet matches with two ratchets, wherein locatees the ratchet activity and is fixed on the housing, and another main transmission ratchet is fixed on the housing by the pull bar activity, pull bar can rotate on housing, linked to each other by backstay between the ratchet of location, two ends, also have the line hole on the housing, backstay is provided with return spring.
The of the present utility model pair of stretching wire grip operation principle of ratchet is: an end of cable or optical cable is passed the line hole on the housing and be fixed in the rotating shaft, use the hand rotating tension bar, main transmission ratchet on it drives ratchet and rotates, meanwhile locate ratchet and under the effect of spring force, be close to ratchet, pull bar stops operating or during return, the location ratchet is fixed ratchet, prevents the ratchet revolution, and control operating rod just can be stretching with optical cable or cable so back and forth.
The of the present utility model pair of stretching wire grip of ratchet is simple in structure, easy to use, a people just can operate, and labour intensity is low, and high efficiency, adopt two ratchet structures to make its more reliable performance, be particularly suitable for the middle use of setting up of power supply department cable and communications industry optical cable.
