Abstract
The utility model provides a positioning structure for cable of puller, which belongs to the technical field of mechanism. The positioning structure for cable of puller is arranged on a shaft tube for coiling the cable. The inner end of the cable is built in one hole of the shaft tube and fixedly connected with the shaft tube. The shaft tube is provided with a cable fixing buckle solidly connected with the shaft tube, and the cable fixing buckle is flaky and has a buckling part which is buckled and pressed on the cable coiled on the shaft tube for a plurality of cycles. The cross section of the buckling part is semicircle shaped. The cable fixing buckle is fixedly connected with the shaft tube via a bolt, a rivet or by means of welding manner. When the cable is pulled to the position of the cable fixing buckle, the cable is hard to be pulled out, which guarantees the normal use of the puller and raises the safe-reliable performance of the puller. The utility model has high practicability.
Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of instrument of drawing, bundle or promoting of being used to.
Background technique
When drawing weight, vehicle or building tent, often to use distractor.Because of distractor has characteristics simple in structure, easy to carry, that tractive force is big, be subjected to liking of user deeply.
Usually, the structure of distractor as shown in Figure 4.The middle part of distractor is a body 5, and there is suspension hook at two ends, and central siphon 1 is arranged on body 5, and the rope 3 that connects with suspension hook is rolled up on central siphon 1.Before distractor uses, the rope of rolling up on central siphon 13 outwards need be pulled out, so that hook weight or vehicle etc.
In the distractor of existing structure, rope 3 the inners are to be connected by being embedded in the hole on the central siphon 1.This mode that is connected is not really firm, in case when rope 3 is all pulled out from central siphon 1, be easy to rope the inner is pulled away from central siphon, directly influence the normal use of distractor and exists certain dangerous hidden danger.
Summary of the invention
The purpose of this utility model is at the problems referred to above, by the rope position structure of distractor is set, prevents that rope breaks away from central siphon, and has simple in structure, safe and reliable characteristics.
The purpose of this utility model can realize by following technical proposal: the rope position structure of this distractor is arranged at the central siphon of the rope that is used to reel, be connected in the hole of the inner embedding central siphon of rope and with central siphon, it is characterized in that, a solid sling that is connected with central siphon also is set on central siphon, Gu sling in the form of sheets, Gu an attaching part is arranged on the sling, this attaching part is withheld and is being rolled up on the rope at a few places of central siphon.
In the rope position structure of above-mentioned index, the shape of cross section of described attaching part is semicircle.
Usually, the attaching part of above-mentioned solid sling is withheld in rolling up on the rope at central siphon one to eight circle place.
In the rope position structure of above-mentioned index, described solid sling is connected by bolt, rivet or welding manner and central siphon.
By solid sling a few of rope the inner are fixed on the central siphon.When the rope of outwards pulling out is pulled to solid sling place, just can't continue to be pulled outwardly, so prevented distractor in use rope all withdraw from, guarantee the normal use of distractor.Owing to roll up in central siphon at rope and with solid sling rope to be withheld again after a few, the existing at this moment bigger winding power of rope, so strengthened the degree that is connected of rope and central siphon, and make rope be difficult to break away from central siphon, improved the safety and reliability of distractor.The utility model has only been set up solid sling, and other component structural of distractor does not change, and it is simple in structure, has higher utility.

Among the figure, 1, central siphon; 2, solid sling; 21, attaching part; 3, rope; 4, bolt; 5, body; 6, handle; 7, suspension hook; 8, ratchet.
Embodiment
As shown in Figure 1, distractor comprises parts such as body 5, handle 6, rope 3, suspension hook 7.Central siphon 1 and ratchet 8 are arranged on body 5, and central siphon 1 is fixed together with ratchet 8.Pull handle 6, drive ratchet 8 and rotate, just rope 3 can be rolled up on central siphon 1.
When distractor uses, pull out rope 3 earlier, and suspension hook 7 is hooked on weight or the vehicle, pull handle 6 again, haul 3 and rope 3 is rolled up on central siphon 1 get final product.
In the utility model, the inner end of rope 3 is identical with normal traction device shown in Figure 4 with the mode that is connected of central siphon 1, promptly opens a hole on central siphon 1, embeds the inner of rope 3 in this hole and is connected with it.
As shown in Figure 2, in the present embodiment, a solid sling 2 is set in that rope 3 is rolled up at first in central siphon 1 three circle places.Gu sling 2 is connected by bolt 4 and central siphon 1.As shown in Figure 3, Gu sling 2 in the form of sheets, the cross section of its attaching part 21 is semicircle.Gu the attaching part 21 of sling 2 is withheld on rope 3.
In the present embodiment, Gu attaching part 21 longitudinal cross-sections of sling 2 are curved.The surface of this shape and central siphon 1 matches, and can improve the firm degree that solid sling 2 is withheld rope 3.
Generally speaking, Gu sling 2 adopts metallic material to make.
