Abstract
The invention discloses a dual-ratchet wire tightener, which comprises a bracket, ratchets, a revolving shaft and a pawl, wherein the revolving shaft is arranged in the bracket; the ratchets are fixed at the two ends of the revolving shaft respectively; each ratchet is matched with the pawl; and the pawl is movably fixed on the bracket. The dual-ratchet wire tightener disclosed by the invention has a simple structure, low labor intensity and high working efficiency, is convenient to use, and can be operated by one person; a dual-ratchet structure is adopted, so that the performance is more reliable; and the dual-ratchet wire tightener is particularly suitable for steel wire ropes in freight transport, and can be switched to single-direction use, so that the application range is enlarged.
Description
Technical field
The present invention relates to a kind of shipping turnbuckle, refer more particularly to a kind of pair of ratchet turnbuckle.
Background technology
At present, in freight industry, bale cargo needs youngster individual operation, and is time-consuming, and effort is very inconvenient.
Summary of the invention
The purpose of this invention is to provide turnbuckle a kind of simple in structure, easy to operate, time saving and energy saving.
The present invention includes support, ratchet, rotating shaft, ratchet, 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 the detent activity is fixed on the support, and pin-and-hole also capable of using carries out one-way operation.
Operation principle of the present invention 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 invention pair of ratchet turnbuckle is simple in structure, easy to use, and a people just can operate, and labour intensity is low, and high efficiency, adopts two ratchet structures to make its more reliable performance, is particularly suitable for steel wire rope use in the shipping.
Description of drawings
Fig. 1 is a structural representation of the present invention
Among the figure: 1 one supports, 2 one rotating shafts, 3 one round end straight-bars, 4 one ratchets, 5 one ratchets, 6-back-up ring, 7 one pin-and-holes, 8-bearing pin.
Concrete real ancient type of banner hoisted on a featherdecked mast mode:
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 load hour use: in advance a gemmule pawl is lifted, passes the pin-and-hole on support and the ratchet with pin, use an other side to get final product.
Claims (8)
1. a two ratchet turnbuckle comprises support, ratchet, rotating shaft, and ratchet is characterized in that: described rotating shaft is located in the support, and two ends are fixed with ratchet respectively, ratchet respectively with click-fit, in case non-return changes.
2. according to claim 1 pair of ratchet turnbuckle is characterized in that: establish a round end straight-bar in the described rotating shaft, the straight-bar front end is a cap shape, in case cotton rope comes off.
3. according to claim 1 pair of ratchet turnbuckle is characterized in that: described support is a steel plate, and the upper end directly is welded on the car body, is out of shape greatly because of loading or ruptures preventing.
