Abstract
The utility model relates to aluminum sheaths and a rope ladder with the same. Each aluminum sheath is annular; a plurality of teeth are formed on the inner surfaces of the two ends of each aluminum sheath, and when the side surfaces of each aluminum sheath are pressed to shrink and deform, the two ends of the aluminum sheath can be used for fastening a coir rope, namely, coir ropes can be fastened and wood boards can be fixed by the aluminum sheathes which are pressed to shrink and deform. The rope ladder comprises a pair of ropes which are formed by buckling the coir ropes together, wherein the buckling joints are held down and fixed by the aluminum sheathes, the wood boards are horizontally arranged between the pair of ropes, corner blocks, of which the points are outward, are vertically and fixedly arranged on the upper and lower surfaces of the two ends of each wood board, respectively, each corner block is embedded between the pair of coir ropes, and the aluminum sheaths are held down and fixed on the coir ropes and are next to the points of the corner blocks. The rope ladder is secure in structure and long in service life.
Description
Technical field
The utility model relates to a kind of aluminium cover and adopts the rope ladder, particularly navigator's rope ladder of this aluminium cover.
Background technology
In existing navigator's rope ladder, the cleat of fixing plank is fastened on coir rope by jag, its winding process is wasted time and energy, production efficiency is low, in long-time use procedure, easily there is the risk of wear and rupture in jag simultaneously, and its life-span is shorter, need running check to safeguard, increased the maintenance cost in use procedure.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of aluminium cover, can compress fastening coir rope fixing plank after shrinkage strain.
In order to solve the problems of the technologies described above, the utility model provides a kind of aluminium cover, and this aluminium cover is annular, and aluminium cover two ends inner surface is provided with multiple teeth and when after the compacted shrinkage strain in side of aluminium cover, aluminium cover two ends are suitable for fastening coir rope.
Another technical problem to be solved in the utility model is to provide a kind of rope ladder, and it is firm in structure, and the life-span is long.
In order to address the above problem, the utility model provides a kind of rope ladder, this rope ladder adopts above-mentioned aluminium cover, it comprises: a pair of rope being formed by the mutual latch closure of coir rope, latch closure place adopts aluminium cover to be fixed, and plank level is located at this between rope, and the upper and lower surface at plank two ends is vertically fixed with respectively tip cleat outwardly, each cleat embeds respectively between a pair of coir rope, on the coir rope of contiguous each cleat tip, is compressed with aluminium cover.
With respect to prior art, the technique effect the utlity model has is:
(1) the aluminium cover in the utility model, can after compacted shrinkage strain, also fix plank by fastening coir rope, its compaction process adopts equipment special, reduce labour intensity, enhance productivity and the compression degree of each aluminium cover unified, the tooth that aluminium puts can, after the distortion of aluminium cover, be bitten coir rope, prevents from sliding between aluminium cover and coir rope;
(2) rope ladder in the utility model, adopts above-mentioned aluminium cover, and it is firm in structure, and long service life has reduced maintenance cost.
Brief description of the drawings
In order to clearly demonstrate innovative principle of the present utility model and the technical advantage than existing product thereof, by applying the limiting examples of described principle, possible embodiment is described by means of accompanying drawing below.In the drawings:
Fig. 1 is the front view of rope ladder in the utility model;
Fig. 2 is the lateral plan of rope ladder in the utility model;
Fig. 3 is the top view of aluminium cover in the utility model;
Fig. 4 is that the A of aluminium cover in the utility model is to view;
Fig. 5 is that in the utility model, aluminium overlaps the top view after compacted contraction.
Detailed description of the invention
As shown in Figure 1 and Figure 2, aluminium cover of the present invention and the rope ladder that adopts this aluminium to overlap, comprising: coir rope 1, aluminium cover 2, plank 3, cleat 4.
Described rope ladder comprises a pair of rope being formed by the mutual latch closure of coir rope 1, this latch closure place adopts aluminium cover 2 to be fixed, be located at this between rope for plank 3 levels of trampling, the upper and lower surface at plank 3 two ends is vertically fixed with respectively and is block trapezoidal cleat 4, the tip of the cleat 4 of plank 3 upper surfaces upward, down, each cleat 4 embeds respectively between a pair of coir rope 1 in the tip of the cleat 4 of plank 3 soffits, is compressed with aluminium cover 2 on the coir rope of contiguous each cleat 4 tips.
As shown in Figure 3 and Figure 4, described aluminium cover 2 is circular cylinder, the two ends cambered surface that aluminium overlaps 2 inner surfaces 21 is provided with multiple teeth 22, in the time compressing the left and right sides of this aluminium cover 2, the two sides of aluminium cover 2 are to center shrinkage strain, as shown in Figure 5, thereby make the two ends fastening coir rope 1 respectively of aluminium cover 2, described tooth 22 can overlap after stress deformation at aluminium, bites coir rope, prevents from sliding between aluminium cover 2 and coir rope 1.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also giving exhaustive to all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or variation still among protection domain of the present utility model.
