Both ends of the elastic tube near the end edges are respectively embedded with a stopper; the guard discs are provided with a plurality of borings for the elastic tube penetrating, and the end edge of the elastic tube which positioned at the stopper can space and clamp at the boring side of the guard discs; and the structure improvement of elastic rope is composed of above means, and one or a plurality of elastic tubes can penetrate between two sets of guard discs according to different physical performances at various ages. The utility model has the advantages of simple structure, convenient adjustment, small volume, no space occupying and being portable.

Description

The stretch cord structural improvement

Technical field

The utility model relates to the exercise class, and particularly a kind of stretch cord structural improvement refers to that especially a kind of elastic tube quantity that can increase and decrease voluntarily according to user's physical efficiency installs, and stretch cord structural improvement that can quick, easy installation location.

Background technology

As everyone knows, general stretch cord, pulling force rope structure comprise: a pedal, its top need form two and hold tread, and pedal two ora terminalis respectively are provided with group connecting part, wherein this group connecting part has two parallel through holes, make to form the retaining shaft of rib between through hole, and between two through holes of retaining shaft of rib hypomere, connection is offered one and is extended out interior narrow V-type clip slot, and is convexly equipped with on the retaining shaft of rib of V-type clip slot bottom to solid sharp dashing forward; Two draw handle, link separately between its end an arch arc body is arranged, and respectively be provided with group seat-joined on the arch arc body stage casing, wherein this group seat-joined has two parallel through holes, make and form the retaining shaft of rib between through hole, and keep off between two through holes of shaft of rib epimere, connection is offered one and is extended out interior narrow V-type clip slot, and is convexly equipped with on the retaining shaft of rib of V-type clip slot bottom to solid sharp dashing forward; Two stretch cords, its upper end is around two through holes that draw group seat-joined, the turning point is pressed from both sides be limited to tool in solid sharp prominent V-type clip slot, the bottom of stretch cord then is around two through holes of pedal group connecting part, the turning point is also pressed from both sides be limited to tool in the V-type clip slot that point is dashed forward admittedly; Form a stretch cord fitness equipment by above-mentioned member, it mainly is to utilize the length of adjusting stretch cord, reach the purpose that changes elastic strength, but its shortcoming is: 1, the tensile strength of the stretch cord that uses is fixed, after the length through adjusting stretch cord, the elastic strength magnitude range that it changed is more not obvious; 2, this product user that can't be suitable for all ages uses, its factor be the intensity of stretch cord if be to set at the beginning at adolescents in male, then general comparatively slim and frahile women, pupil or aging people just draws motionless at all; If the intensity of stretch cord is designed at general women at the beginning, though it can be through adjusting the contraction in length of rope, reach and become the intensity that changes stretch cord, but rope is too short, when executable operations, have the shortcoming that can't stretch skill, and this type of design also can't provide the child to use, and is the problem that need solve.

The utility model content

According to the purpose of this utility model, shortcoming at above-mentioned stretch cord existence commonly used, a kind of stretch cord structural improvement is provided, and it comprises: at least one or one or more elastic tube and number location block plate form, these elastic tube two ends respectively are nested with a block near the ora terminalis place; This block plate is provided with number perforation, can provide elastic tube to place, and make the elastic tube ora terminalis be positioned at the block place can spacing block in perforation one side of block plate; Form by above-mentioned member, can be between two groups of block plates according to one or several elastic tube of the different perforation of physical efficiency of all ages.

Advantage of the present utility model is: simple structure, easy to adjust, volume lightly, do not take up space, easy to carry, the people who is suitable for all ages uses.

Description of drawings:

Fig. 1 is a decomposing schematic representation of the present utility model;

Fig. 2 is a combination partial schematic sectional view of the present utility model;

Fig. 3 is a combination schematic top plan view of the present utility model.

The specific embodiment:

To shown in the accompanying drawing 3, the utility model comprises the elastic tube 10 of one or more and counts block plate 20 and form as accompanying drawing 1; Wherein, these elastic tube 10 two ends respectively are arranged with the block 11 of a circle footpath greater than the elasticity caliber, make elastic tube 10 two ends be a convex blocking ring 12; This block 11 generally is the cucurbit shape, and the calabash body diameter at its two ends is wide greater than perforation 21 footpaths of block plate 20, and narrower its width of interlude in circle footpath is about the thickness of two block plates 20;

The identical block plate 20 of this structure central shaft to and be looped around central shaft and be provided with number perforation 21 to the outside, this each perforation 21 all is provided with profile groove 22 and extends the placing edge, wherein, 21 the footpath of boring a hole is wide just is the diameter of elastic tube 10 for each, advances for elastic tube 10 and can guide block fast in perforation 21 places via the openend of profile groove 22

Block plate 20 and subsides are one group in twos, and set 21 the profile groove 22 of respectively boring a hole of upper and lower block plate 20 is staggered mutually, can provide the convex blocking ring 12 firm blocks at elastic tube 10 two ends spacing, provide the user to consider the numbers that increase and decrease elastic tube 10 voluntarily in 20 of two groups of block plates according to each one physical efficiency limit to reach in perforation 21 places of block plate 20.

Moreover, mode of operation of the present utility model, the stretch cord that provides user's both hands can be gripped on two groups of block plate relative inner respectively can draw back stretch cord like this and make its outside extension, and then reaches the effect of sport and body-building.

Other is the person, the utility model is provided with the several blocking salient points 23 and the location arc groove 24 of mutual correspondence at the nearly peripheral region of upper and lower end face of each block plate 20, advance to provide when two block plates 20 are stacked, can pull in the location of another block plate 20 arc groove 24 and blocking salient point 23 by each the blocking salient point 23 and location arc groove 24 embeddings of a block plate 20, reach 21 effects of correspondence mutually all of respectively boring a hole as auxiliary two block plates 20.
