Abstract
A double-ratchet-wheel tightener comprises a supporting bracket, rachet wheels, a rotating shaft and pawls, wherein the rotating shaft is arranged in the supporting bracket, the two ends of the rotating shaft are fixed with the ratchet wheels respectively, each rachet wheel is engaged with the pawls, and the pawls are movably fixed on the supporting bracket. The double-ratchet-wheel tightener of the utility model, with simple structure and convenient application, can be operated by one people, and the labor intensity is low, the work efficiency is high. The double-ratchet-wheel structure is adopted, thereby the performance is more reliable, the utility model is particularly applicable to freight steel wire ropes, and the utility model can also be converted to unidirectional use, the range of use is enlarged.
Description
Technical field
The utility model relates to a kind of shipping turnbuckle.
Background technology
At present, in freight industry, bale cargo needs several people's operation, and is time-consuming, and effort is very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and is easy to operate, time saving and energy saving turnbuckle.
The utility model comprises support, ratchet, rotating shaft, ratchet, and rotating shaft is located in the support, establish a round end straight-bar on the axle, the axle two ends are fixed with ratchet respectively, and each ratchet matches with ratchet, wherein locate the ratchet activity and be fixed on the support, also can utilize pin-and-hole to carry out one-way operation.
Principle of work of the present utility model is: with cotton rope around being pressed on the round end straight-bar, rotating shaft then, rotating shaft drives ratchet and rotates, ratchet carries out interlock with ratchet simultaneously, when rotating shaft stopped operating, ratchet was fixed ratchet, prevented to turn round.
Of the present utility model pair of ratchet turnbuckle is simple in structure, easy to use, and a people just can operate labor
Fatigue resistance is low, and high efficiency, adopts two ratchet structures to make its more reliable performance, is particularly suitable for steel rope use in the shipping.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
1-support 2-rotating shaft 3-round end straight-bar 4-ratchet 5-ratchet
6-back-up ring 7-pin-and-hole 8-bearing pin
The specific embodiment:
Around being pressed on the round end straight-bar 3, rotating shaft 2 then with cotton rope, and rotating shaft 2 drives ratchet 4 and rotates, and ratchet 5 carries out interlock with ratchet 4 simultaneously, and when rotating shaft stopped operating, ratchet 5 was fixing with ratchet 4.
One-way operation is that load hour uses: in advance a gemmule pawl is lifted, pass pin-and-hole on support and the ratchet with pin, use an other side to get final product.
