Abstract
The utility model discloses a ratchet wheel tightener which comprises a machine shell, a rotating shaft, a ratchet wheel and a pawl, and is characterized in that the machine shell is provided with a fixed pin, an axle mounting hole and a machine shell connecting rod; the rotating shaft is arranged in the axle mounting hole; the pawl is arranged on the fixed pin and is connected with the machine shell; the ratchet wheel is connected with the rotating shaft by a flat key arranged on the rotating shaft; and the ratchet wheel is meshed with the pawl. In order to enable a rotating wrench to do repetitive motion in a small angle range and drive the rotation shaft to rotate, the ratchet wheel tightener is provided with a torsion spring on the fixed pin, the pawl is connected with the machine shell by the torsion spring, one end of the rotating shaft is provided with the rotating wrench, and a bearing is arranged between the rotating shaft and the axle mounting hole. The ratchet wheel tightener is simple in structure and operation and high in safety, and can be firmly fixed so as not to be easily rocked, thereby leading tightening work to be more easily carried out and bringing great convenience and safety to the work of workers.
Description
Technical field
The utility model relates to a kind of tightening device of electric wire, particularly a kind of ratchet wire grip.
Background technology
Electric wire adopts the method for artificial tension to the tightening process great majority of electric wire in installation process at present, this method is bigger to working strength of workers, the stringing effect is relatively poor, the stringing that has is to be undertaken by the adjusting of rotating spanner and bolt, nut, this method makes the electric wire rotation easily, need to be equipped with particular tool simultaneously, open-air unwrapping wire operation is made troubles.
Summary of the invention
The purpose of this utility model is that a kind of simple in structure, safe, ratchet wire grip that stringing is effective is provided for the deficiency that solves above-mentioned technology.
In order to achieve the above object, a kind of ratchet wire grip that the utility model is designed, it comprises casing, rotating shaft, ratchet and pawl, it is characterized in that described casing is provided with steady pin, axle installing hole and casing connecting rod, rotating shaft is located in the installing hole, and ratchet is located on the steady pin and links with casing, ratchet links by flat key and the rotating shaft that is located in the rotating shaft, the ratchet and pawl engagement.In order to make rotating spanner motion repeatedly in the scope of smaller angle, drive rotating shaft simultaneously and rotate, described steady pin is provided with torsion spring, and ratchet is to link by torsion spring and casing, on rotating shaft one end, be provided with rotating spanner, between rotating shaft and axle installing hole, be provided with bearing.For being arranged, enough spaces regulate the length of retractable cable in the stringing process, and fix tightening up steel wire simultaneously, described rotating shaft is provided with U-lag and tighten up steel wire, the end of tightening up steel wire be located in the U-lag after rotating shaft is connected, tighten up the other end and the binding of casing connecting rod of steel wire.For can be more firm fix the ratchet wire grip, it can arbitrarily not rocked in the stringing process, be provided with the stringing hook between described rotating shaft and the casing connecting rod, the stringing hook is provided in a side of and tightens up on the steel wire, is provided with fixed pull ring on casing.
A kind of ratchet wire grip that the utility model provides, it is not only simple in structure, and is simple to operate and safe, and can be firm fix is difficult for rocking, and makes that stringing work is easier to be carried out, for workman's work brings great convenience and safety.
