As Fig. 1, shown in 2, the utility model provides the stay cord fitness equipment, it mainly comprises the holder 20 of enclosed shape in the form of a ring, wherein end at holder 20 is provided with a cone-type piercer 21, and in this perforation 21, place a locating rack, the top of this locating rack has a spheroid 30, spheroid 30 bottoms are extended a connecting rod 31 downwards, and place restrictions on ring 32 in the bottom level extension one of this connecting rod 31, placing restrictions on ring 32 can arrange in pairs or groups and one adjust folder 40 milk and use, this adjusts folder 40 promptly as Fig. 3, can in placing restrictions on ring 32, move shown in 4, place restrictions on the aperture of ring 32 with adjustment, its occupation mode then as shown in Figure 5 the end with stay cord 40 is passed and is placed restrictions on ring 32, passes the bellmouth 21 of holder 20 again, can stay cord 50 be compressed in the bellmouth 21 by the spheroid 30 by locating rack.

Above-mentioned is general configuration situation of the present utility model, and its detailed structure then is described as follows:

Please cooperate referring to Fig. 1 and shown in Figure 2, this is the structure situation of the utility model one embodiment, wherein, one end of holder 20 is formed with can be for the grip part of user's hand gripping, end then is provided with a bellmouth 21 in addition, this bellmouth 21 is bigger towards the diameter of holder 20 inner ends, then diameter is less for an end toward the outer side, spheroid 30 sphere diameters of locating rack are then between the big small-bore of bellmouth 21, make spheroid 30 to penetrate from maximum gauge one end of bellmouth 21, but be unlikely from minor diameter one end passing, and a connecting rod 31 is extended in spheroid 30 bottoms, these connecting rod 31 bottom horizontal-extendings one enclosed shape is as shown in Figure 2 placed restrictions on ring 32, this is placed restrictions on and forms a projection between ring 32 end faces and the connecting rod 31, this projection be provided with one with place restrictions on ring 32 grooves that communicate 33, place for adjusting folder 40

This adjustment folder 40 1 has the pressure section 41 of I shape, and end is one group of afterbody 42 in addition, wherein, but these pressure section 41 two ends form clipping at the short slot 410 of placing restrictions on ring 32 annular periphery, and between two short slots 410, do not establish and then be provided with several protruding grains 411 on pressure section 41 end faces of afterbody 42, thus to suppress in stay cord, in addition, the afterbody 42 of being located at pressure section 41 other ends is design in groups, and it has two intermediate plates 420, has the gap between two intermediate plates 420, and away from the V-shaped more greatly and slightly design in the gap of pressure section 41 1 ends, so that have deformable compression stroke between 420 liang of intermediate plates 420 of two intermediate plates, and the outside of two intermediate plates 420 then is provided with fixture block 421 at interval relatively.

As shown in Figure 3, desire is combined in placing restrictions on of locating rack with above-mentioned adjustment folder 40 and encircles at 32 o'clock, be that short slot 410 folders that will adjust pressure section 41 both sides of folder 40 encircle 32 periphery across placing restrictions on, 42 of two afterbodys adjusting folder 40 pass be positioned at place restrictions on ring 32 tops wear groove 33, and wherein one group of fixture block 421 of being located at two afterbodys, 42 outsides is fastened in the notch of wearing groove 33, during desire assembling stay cord 50, be that stay cord 50 is passed the pressure section 41 of adjusting folder 40 and places restrictions on the formed space of ring 32 inner peripherals, the application of force afterbody that will adjust folder 40 two intermediate plates 420 compresses in opposite directions then, make the fixture block 421 of being located at its outside break away from and the blocking state of wearing groove 33, to adjust again folder 40 as shown in Figure 4 towards stay cord 50 pushing and pressing, force stay cord 50 distortion and clipping is encircled between 32 the inner edge with placing restrictions in each protruding grain 411 of adjusting folder 40 pressure sections 41, decontrol the strength of bestowing two intermediate plates, 420 afterbodys then, two intermediate plates, 420 afterbodys are opened because of elastic returning, the fixture block 421 in its outside is fastened on again in the notch of wearing groove 33, and forms the blocking state.

Above-mentioned stay cord 50 with place restrictions on ring 32 and form the blocking states and promptly can't deviate from later on, and the stay cord 50 ends less end of bellmouth 21 internal diameters by holder 20 as shown in Figure 5 penetrates, pass by the bigger end in aperture again, when both hands grip holder 20 and during stretching stay cord 50, can make the spheroid 30 on locating rack top be spurred by stay cord 50 and stay cord 50 is located between spheroid 30 and the bellmouth 21.

From the above, the utility model passes the length number of groove according to the afterbody 42 of adjusting folder 40, and change its pressure section and place restrictions on the formed space of ring size, to cooperate suitable stay cord 50 specifications, that is, when desire is assembled thicker stay cord 50, the afterbody 42 of adjusting folder 40 can be stretched outward, to strengthen its assembling space, and when stay cord is thin, then afterbody 42 is got final product toward placing restrictions on ring one end retraction, it is presented can change the design of placing restrictions on annular space, to be suitable for the stay cord of plurality of specifications, improve its applicability.

Structure situation such as Fig. 6 of locating rack among another embodiment of the utility model, shown in 7, its two different ellipses in aperture of connecting rod 31 bottom horizontal-extendings at locating rack are placed restrictions on ring 34,35, two place restrictions on ring 34, on 35 the inner peripheral minor axis, be provided with two protruding grains 36 respectively relatively, when the diameter of stay cord 50 is thick, it can pass as illustrated in fig. 7 places restrictions on ring 34 inner edges, the whole inner peripheral of placing restrictions on ring 34 that is full of, and utilize two protruding grains 36 to snap in stay cord 50 and increase its chucking power, if when being replaced by the stay cord than small dimension, then can be set in less the placing restrictions in the ring 35 in another aperture, when desire is assembled thinner stay cord 50, then stay cord 50 is placed through two 36 and 1/2 of protruding grains and places restrictions on the formed space of ring 34 inner edges, therefore, change the space of placing restrictions on ring in the adjustment mode as described above though this embodiment is non-, but it still can place stay cord whole placing restrictions in the ring, or place restrictions on a half space of ring, and it has two rings of placing restrictions on not of uniform size altogether, adding stay cord is elastomer, the stay cord of applicable approximately 2～3 kinds of specifications in same aperture, thus, the whole design of placing restrictions on ring is the stay cord of applicable plurality of specifications, make the cost that the locating rack of plurality of specifications is derived and reach minimizing, and for the consumer, when desire is changed different flexible stay cord, as long as select to buy stay cord, and need not to purchase again locating rack, can reduce consumer's burden.

In sum, the utility model stay cord fitness equipment mainly holder is provided with a bellmouth, and a locating rack is set in bellmouth, this locating rack one end has the spheroid that can place in the bellmouth, end then is provided with one and places restrictions on ring in addition, pass after the bellmouth of placing restrictions on ring and holder for stay cord, utilization is positioned at the spheroid of bellmouth, the stay cord blocking can be located, and according to user's height and demand and adjust the length of pulling out of stay cord, and then adjust length between two holders, reach the scope of application that enlarges the stay cord fitness equipment.

The utility model stay cord fitness equipment is owing to can adjust the stay cord of adapted plurality of specifications and be easy to change pulling rope length, thus to adjust the elasticity of stay cord fitness equipment, simultaneously can make the consumer not increase the stay cord of choosing plurality of specifications under the too many expense, the consumer is provided more choice, therefore, very practical.
