Abstract
The utility model relates to a rope fixed structure of a retractor, which belongs to the field of the mechanical technology, which particularly relates to a tool used for towing, binding or lifting. A rope fixed structure of the retractor is arranged on a shaft pipe used for winding a rope in the retractor, a positioning hole is arranged on the shaft pipe and the inner end of the rope is embedded in the positioning hole. The surface of the shaft pipe is provided with a groove, and the groove using a hole opening of the positioning hole as a starting point is extended towards the winding direction of the rope. Obviously, when the rope is wound on the shaft pipe, a small section on the initial end of the inner end of the rope is positioned in the groove. The rope fixed structure of the retractor completely eliminates the bulge phenomenon when the rope is wound on the shaft pipe, the stress of the rope is uniform, and thus, the rope is difficult to break in use and the service life of the retractor is prolonged. Simultaneously, the fixed structure of the utility model has the advantages of reasonable design and easy enforcement.
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 technology
When drawing weight, vehicle or building tent, often to use tractor.The structure of tractor as shown in Figure 7, the middle part of tractor is a body 4, there is suspension hook 5 at two ends.Central siphon 1 is arranged on body, and the rope 2 that connects with suspension hook 5 is rolled up on central siphon 1.When tractor uses, the rope of rolling up on central siphon 12 outwards need be pulled out, so that hook weight or vehicle etc.
As shown in Figure 8, in the tractor of existing structure, rope 2 is inner to embed in the knock hole of central siphons 1 and is connected.Could roll up on central siphon need to bend a angle after coming out in rope 2 the inners from knock hole after greater than 90 degree.Because actual used ropes such as steel cable all have certain rigid, so rope has the projection 16 of outside protrusion in this bending place.And, rope how many layers of on central siphon, reeling no matter, rope position herein has projection 16 to exist all the time.Like this, rope circle partially occurs after being wound in central siphon, causes the discontinuity equalization of rope, and rope is ruptured easily, has directly influenced the service life of tractor.
Summary of the invention
The purpose of this utility model is at the existing the problems referred to above of existing tractor, and a kind of rope fixing structure of structure improved tractor is provided, and it is eliminated rope and is wound in existing protruding phenomenon on the central siphon, thereby makes the rope stress equalization.
The purpose of this utility model can realize by following technical proposal: the rope fixing structure of this tractor is arranged at the central siphon of the rope that is used in the tractor to reel, a knock hole is arranged on central siphon, the inner of rope embeds in the knock hole, it is characterized in that, the surface of described central siphon has a groove, groove is that the aperture with knock hole is a starting point, extends towards the coiling direction of rope.Obviously, after rope is wound in central siphon, initial a bit of being in the groove of rope the inner.
In the rope fixing structure of above-mentioned tractor, the length of described groove was grown between the girth in 1/8 week of central siphon.
In the rope fixing structure of above-mentioned tractor, described central siphon surface has a cross sectional shape to be the chevron pointing chase vertically, and the aperture of above-mentioned knock hole is on the side of chase.This structure makes to be wound on the tubular axis with the surperficial tangent angle of central siphon with one by the rope that comes out in the knock hole; Simultaneously, rope also is in the above-mentioned groove herein, so finish the protruding phenomenon of having eliminated rope, makes rope stress equalization in use.
In the rope fixing structure of above-mentioned tractor, a mounting hole is arranged on central siphon, and mounting hole communicates with knock hole, and hole size is installed greater than the location hole size, an end socket is arranged in the inner of rope, and the size of end socket is between mounting hole and location hole size.Like this, end socket can pass through mounting hole and the impassabitity knock hole.Therefore, the inner of rope can be inserted in the central siphon by mounting hole, moves to the knock hole place then, and rope and central siphon are connected.
In the rope fixing structure of above-mentioned tractor, a retaining sheet is arranged between mounting hole and knock hole on the described central siphon, retaining sheet and central siphon are connected as a single entity.When packing the inner of rope into knock hole by mounting hole, need cocked retaining sheet to pass through for rope.After installation, push retaining sheet, stop that rope returns mounting hole by knock hole.
Compared with prior art, the rope fixing structure of this tractor makes the stress equalization of rope owing to eliminated protruding phenomenon when rope is wound in central siphon fully, so rope easy fracture not in use can prolong service life of tractor.Simultaneously, this fixed sturcture reasonable in design, implement to have higher utility easily.

Among the figure, 1, central siphon; 11, knock hole; 12, groove; 13, mounting hole; 14, retaining sheet; 15, chase; 16, projection; 2, rope; 21, end socket; 3, ratchet; 4, body; 5, suspension hook.
The specific embodiment
As shown in Figure 7, tractor comprises parts such as body 4, rope 2, central siphon 1, suspension hook 5, ratchet 3.Central siphon 1 is fixed together with ratchet 3, is loaded on the body 4, and rope 2 is used to reel.Suspension hook 5 is in the two ends of tractor.The rope fixing structure of this tractor is arranged on the central siphon 1, by this anchor fitting, the inner of rope 2 is linked to each other with central siphon 1.
As depicted in figs. 1 and 2, a knock hole 11 is arranged on central siphon 1, the inner of rope 2 embeds in the knock hole 11.In the present embodiment, an end socket 21 is arranged in the inner of rope 2.It is that material is made that end socket 21 adopts aluminium, is fixed together with the inner of rope 2.The size of end socket 21 is greater than the aperture of knock hole 11.After the inner of rope 2 embeds knock hole 11, utilize stopping of end socket 21, make rope 2 can not break away from central siphon 1.
As shown in Figure 5, a mounting hole 13 is arranged on central siphon 1.Mounting hole 13 communicates with knock hole 11, and the size of mounting hole 13 is greater than the size of knock hole 11 and end socket 21.Therefore, rope 2 the inners that have end socket 21 at first can be inserted in the central siphon 1 by mounting hole 13, move to knock hole 11 places then, rope 2 and central siphon 1 are connected.
As shown in Figure 5, a retaining sheet 14 is arranged between mounting hole 13 and knock hole 11, retaining sheet 14 is connected as a single entity with central siphon 1.In the present embodiment, central siphon 1 adopts metallic material to make.Retaining sheet 14 is connected as a single entity with central siphon 1, is thin sheetmetal.As shown in Figure 3, when packing the inner of rope 2 into knock hole 11 by mounting hole 13, need cocked retaining sheet 14 to pass through for rope 2.After installation, push retaining sheet 14 and get final product.Retaining sheet 14 plays and stops that rope 2 return the effect of mounting hole 13 by knock hole 11.
As shown in Figure 5 and Figure 6, a groove 12 is arranged on the surface of central siphon 1.Groove 12 is a starting point with the aperture of knock hole 11, extends towards the coiling direction of rope 2.As shown in Figure 4, the inner of rope 2 at first is wound in the groove 12, just rolls up other surface in central siphon 1 then.In the present embodiment, the length of groove 12 is equivalent to 1/4 of central siphon 1 girth.
Have a cross sectional shape to be chevron pointing chase 15 vertically on central siphon 1 surface, the aperture of knock hole 11 is on the side of chase 15.As shown in Figure 2, this structure makes and to be wound on the tubular axis 1 with the surperficial tangent angle of central siphon 1 with one by the rope 2 that comes out in the knock hole 11, and is in the groove 12.Obviously, in this fixed sturcture, the protruding phenomenon of rope 2 has been eliminated, and rope 2 can be close to central siphon 1, is wound on the central siphon 1 stress equalization.
