Description

Steel-wire fastener

Technical field

The utility model relates to the complete rigging of a kind of steel-wire fastener, relates in particular to a kind of complete rigging of steel-wire fastener with secondary locking functions.

Background technology

Transporting in the loading and reinforcing, the operation defective is that artificial strength is little by artificial pulling for rope fastening normal in the past, is difficult for fasteningly, and to be ropes loosening for the normal because vibrations of jolting in transportation, causes the goods displacement, thereby shipping accident takes place.Utility model patent 200720151699.7,200720000112.2,200720195007.9,200720148797.5,200720128173.7 has been announced some steel-wire fasteners, these steel-wire fasteners make that rope is easier to be tightened up, and operate more conveniently, work efficiency is than greatly improve in the past.But the steel-wire fastener that aforementioned utility model is announced also comes with some shortcomings, and mainly is also will pass leadout hole or pilot hole after steel rope penetrates eyelet hole, operates comparatively loaded down with trivial details inconvenience.

The utility model content

Technical problem to be solved in the utility model provides a kind of steel-wire fastener, makes that steel rope is easier to be tightened up, and is simple and efficient to handle, thereby overcomes the deficiency of complex operation inconvenience in the above-mentioned prior art.

For solving the problems of the technologies described above, the utility model is taked following technical scheme:

A kind of steel-wire fastener, comprise support, ratchet, ratchet shaft, it is characterized in that described support is a U-shaped, end at the both sides otic placode leaves axis hole, two semiaxis are installed above, leave the slit between two semiaxis, leave two semiaxis holes on the ratchet and be fixed on two semiaxis by the semiaxis hole, also leave a square hole between two semiaxis holes of ratchet, be equipped with clamp and stage clip on the U-shaped support, clamp closely is fastened on the ratchet by stage clip, the U-shaped handle is connected on two semiaxis by the axis hole on the otic placode of handle both sides, and a bolster and a torsion spring are arranged on the U-shaped handle, is equipped with clamp on the bolster, clamp closely is fastened on the ratchet by torsion spring, and the bottom of U-shaped handle is a handle.

The otic placode of described U-shaped handle is installed in the outside of ratchet, between the otic placode of U-shaped handle and ratchet, be equipped with packing ring, respectively be installed with a semiaxis pin at the two ends of two semiaxis, the semiaxis pin connects together two semiaxis and prevent and moves axially, the both sides otic placode of U-shaped support links together by bearing pin at the other end, spacer is arranged on the bearing pin, and spacer separates otic placode.

Described U-shaped support both sides have slideway, clamp on the described U-shaped support is that U-shaped and both sides are installed in the slideway, the width of clamp both sides is identical with the thickness of ratchet and be fastened on the ratchet, clamp on the described U-shaped handle is a U-shaped, the both sides width is identical with ratchet thickness and be fastened on the ratchet, is equipped with handle axle before the handle of U-shaped handle.

By the aluminium cover steel rope is installed on the bearing pin of described U-shaped support.

Owing to adopt said structure, make the utility model compared with prior art have following advantage:

1, the slit between two semiaxis is used for reeve, than adopting the easier steel wire penetrating that makes of eyelet hole, and can passes, avoid fag end is twined together from the ratchet square hole;

2, adopt handle extrusion ratchet to rotate, and, make operation more laborsaving quick without pliers twisting ratchet shaft.

The scheme drawing that when Fig. 3 steel-wire fastener uses goods is fastened

1, torsion spring 2, ratchet 3, clamp A 4, bolster 5, otic placode 6, bearing pin 7, U-shaped support 8, packing ring 9, semiaxis pin 10, semiaxis 11, stage clip 12, clamp B13, spacer 14, handle axle 15, square hole

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

As shown in Figure 1 and Figure 2, U-shaped support 7 is stamped to form by steel plate, by bearing pin 6 the both sides otic placode is coupled together, and also has a spacer 13 on bearing pin 6, so that otic placode separates fixed range.Otic placode one end has two axis holes, be equipped with two semiaxis 10 above, two semiaxis curved surfaces are outside, and the plane is relative and leave certain distance, be able to pass steel rope apart from size, leave two semiaxis holes on the ratchet 2, leave square hole 15 between two semiaxis holes, the distance between the semiaxis hole equates with distance between the semiaxis, makes semiaxis pass the semiaxis hole, thereby two ratchets are rack-mount respectively and in the outside of support otic placode, packing ring 8 is installed outside ratchet.Otic placode middle part at U-shaped support 7 has slideway, be equipped with a U-shaped clamp 12 in the slideway, clamp two ends width is identical with ratchet thickness and closely be fastened on the ratchet, the clamp back is equipped with stage clip 11, when ratchet 2 clockwise directions rotate, clamp 12 is by ratchet extruding recession, and clamp 12 blocks ratchet and prevents that ratchet from rotating counterclockwise under stage clip 11 effects when ratchet stops operating.The U-shaped handle is stamped to form by steel plate, one end is an otic placode 5, leaving axis hole on the otic placode and being installed on the semiaxis 10, is separated with packing ring 8 between handle otic placode and the ratchet 2, the semiaxis outermost end is installed with semiaxis pin 9, comes off to prevent other parts on semiaxis axial rotation or the semiaxis.The handle other end is a handle, and leader's axle 14 is arranged before the handle, and otic placode 5 middle parts are equipped with a bolster 4 and a torsion spring 1, be equipped with U-shaped clamp 3 on the bolster 4, clamp 3 both sides width are identical with ratchet thickness, and torsion spring 1 one ends are positioned on the clamp, by torsion spring 1 the clamp two ends closely are fastened on the ratchet 2.Clamp 3 can only and can not slide along the U-shaped handle around the bolster rotation, when manually pressing lower handle, clamp 3 pushes ratchets 2 and the ratchet clockwise direction is rotated, when handle newly lifts by laying equal stress on to the bottom, clamp 3 be subjected to ratchet 2 squeeze moving rotate counterclockwise the back merger conveniently handle lift in the lump, following once more on time when handle, clamp 3 pushes ratchet 2 once more clockwise rotates ratchet.So circulation.

For easy to use, can on the bearing pin of U-shaped support, be equipped with steel rope by aluminum pipe.

In fastening the process of goods, as shown in Figure 3, after steel rope is walked around the goods of institute's bolt, an end is inserted half interaxle slit and pass artificial preliminary tension from square hole 15, fixed handle is pressed in circulation then, ratchet is constantly rotated, and drive two semiaxis rotations synchronously, the semiaxis rotation is about to steel rope and is wrapped on the semiaxis, rotate the number of turns increase winding number of turn is increased, thereby steel rope constantly is tightened up.
