Abstract

The utility model discloses an annular rope without a sewing joint, which comprises a sheath and a core, wherein the core comprises a plurality of branch cores, each group of branch cores comprises a plurality of groups of inner cores, the plurality of groups of inner cores are twisted and stranded to form a branch core, the plurality of branch cores are twisted and stranded to form a strand of core, and the core is fixed in the sheath in a surrounding manner; the twisting ply quantity of the branch cores in the covering core is matched with the diameter of the outer skin, the quantity of the inner cores which are not arranged in each group of branch cores is an integer, compared with a traditional rope ring or a braid ring which is sewn in a head-tail connection mode, the product has the advantages that a sewing joint is not arranged, if the traditional rope ring or the braid ring is worn at the sewing position of the joint sewing thread or the stress point is arranged at the sewing position, the integral strength is greatly lost, and the product is formed by encircling a strand of continuous fibers by dozens of circles, the integral strength is formed by the friction force between each circle of fibers, and therefore, the strength of each position of a finished product ring is the same and has no weakness.

Description

Endless rope without sewing joint

Technical Field

The utility model relates to the field of endless ropes, in particular to an endless rope without a sewing joint.

Background

The annular rope is formed by winding a plurality of fine steel wires and is connected end to form a closed loop.

The existing annular rope structure with the joint can have a certain influence on the structural strength of the rope body.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the endless rope without the sewing joint, compared with the traditional rope ring or the braid ring with the head-to-tail joint sewing, the endless rope ring or the braid ring without the sewing joint has the advantages that if the sewing thread at the sewing position of the joint is worn or the stress point is at the sewing position, the integral strength is greatly lost, and the endless rope without the sewing joint is formed by encircling a strand of continuous fibers for dozens of circles, and the integral strength is formed by the friction force between each circle of fibers, so that the strength of each position of the finished product ring is same without weakness.

In order to solve the technical problems, the utility model provides the following technical scheme: the utility model provides a no sewing joint's annular rope, includes crust and covering, include stranded core in the covering, every group all include the multiunit inner core in the core, stranded inner core forms a strand core through twisting plying, stranded core forms a strand covering through twisting plying, the covering is fixed around in the crust.

As a preferable technical scheme of the utility model, the twisting and plying number of the branch cores in the core-spun is matched with the diameter of the outer skin, and the number of the inner cores in each group of branch cores is an integer.

Compared with the prior art, the utility model has the following beneficial effects:

compared with the traditional rope ring or ribbon ring with the head and tail connected with the sewing, the product has the advantages that no sewing joint exists, if the sewing thread at the sewing position of the traditional sewing rope ring or ribbon ring is worn or the stress point is at the sewing position, the integral strength is greatly lost, and the product is formed by encircling a strand of continuous fibers for dozens of circles, and the integral strength is formed by the friction force between the fibers of each circle, so that the strength of each position of the finished product ring is the same without weakness.

Detailed Description

In order that the manner in which the above recited features, objects and advantages of the present utility model are obtained will become readily apparent, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Based on the examples in the embodiments, those skilled in the art can obtain other examples without making any inventive effort, which fall within the scope of the utility model. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents, etc. used in the following examples are commercially available unless otherwise specified.

Embodiment one:

as shown in fig. 1 to 4, the present utility model provides a loop rope without a sewing joint, which comprises a sheath 1 and a core 2, wherein the core 2 comprises a plurality of branch cores 21, each group of branch cores 21 comprises a plurality of groups of inner cores 22, the plurality of branch cores 22 are twisted to form a branch core 21, the plurality of branch cores 21 are twisted to form a strand of core 2, and the core 2 is fixed in the sheath 1 in a surrounding manner.

In other embodiments, the number of twisted strands of the cores 21 in the core-spun 2 is adapted to the diameter of the sheath 1, and the number of inner cores 22 inside each set of cores 21 is an integer; compared with the traditional rope ring or ribbon ring with the head and tail connected with the sewing, the product has the advantages that no sewing joint exists, if the sewing thread at the sewing position of the traditional sewing rope ring or ribbon ring is worn or the stress point is at the sewing position, the integral strength is greatly lost, and the product is formed by encircling a strand of continuous fibers for dozens of circles, and the integral strength is formed by the friction force between the fibers of each circle, so that the strength of each position of the finished product ring is the same without weakness.

Embodiment two: as shown in fig. 5, the first embodiment is a self-winding belt structure can be used as the outer skin 1, and the fastening is realized by winding.

Embodiment III: as shown in fig. 6, the outer skin 1 can be combined and fixed with the core 2 by using a flat webbing folding method based on the first embodiment.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the above-described embodiments, and that the above-described embodiments and descriptions are only preferred embodiments of the present utility model, and are not intended to limit the utility model, and that various changes and modifications may be made therein without departing from the spirit and scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
