See also Fig. 1 and Fig. 2, show the stay cord body-building device that constitutes according to the utility model first embodiment, it comprises an elastic threads assembly 1 and plural handle 2; This elastic threads assembly 1 comprises at least two to have the elastic threads 11 of back stretch and is plugged on connecting rod 12 in the end of each elastic threads 11, and each handle 2 is assembled in and uses in order to provide to grip on the end of each elastic threads 11; In the present embodiment, this elastic threads assembly 1 comprises the elastic threads 11 of six loop shapeds that link together and constitute, and each elastic threads 11 preferably has different coefficient of elasticity; Perhaps, shown in the embodiment of Fig. 6, this elastic threads assembly 1 connects into strip by the elastic threads 11 that several have different coefficient of elasticity.

Cooperate Fig. 2 and shown in Figure 3, each elastic threads 11 has one first end 111 (right-hand member among the figure) and one second end 112 (left end among the figure), and these elastic threads 11 inside have hole 113, and the part at least of this connecting rod 12 has the external diameter big than the aperture, end of this elastic threads, it can utilize urgent fit mode to insert in the end hole 113 of each elastic threads the end of each elastic threads 11 is supportted greatly, in Fig. 2, about half length in the end hole 113 of each connecting rod 12 urgent two elastic threads inserting phase and connect, the outer end that first end 111 and second end 112 of adjacent two elastic threads, 11 adjacency is placed in connector 12 respectively just, and two elastic threads are combined, promptly each connecting rod 12 inserts in the end hole of an elastic threads 11 of being correlated with half length.Perhaps, as shown in Figure 6, when in 12 elastic threads 11 at the two ends of this elastic threads assembly 1 of this connecting rod, it can most ofly insert in the end hole in order to form windings more positively with handle 2.

Cooperate Fig. 2 and shown in Figure 4, this handle 2 has an axial bore 21 and is the outer surface 22 of egg shape without exception, can add a protection pad 221 grips the frictional force of this handle 2 and feel preferably is provided in order to increase the user at these handle 2 outer surfaces 22 places, and this endoporus 21 axially runs through the forward and backward end 23 of this handle 2, and the length of this endoporus 2 is big than this connecting rod 12, makes each handle 2 can coat elastic threads 11 ends of this socket connection bar 12.

This endoporus 21 comprises both ends open 211 and the position middle hole wall 212 between this two opening 211; This both ends open 211 has first aperture size, this first aperture size system can provide elastic threads 11 to cooperate and take in, and this centre hole wall 212 has one second aperture size, this second aperture size is big than this first aperture size, and can provide elastic threads 11 ends that are plugged with connecting rod 12 to cooperate and take in, make each elastic threads 11 both ends and each handle 2 energy strong bonded together.

In the present embodiment, middle hole wall 212 profiles of this endoporus 21 match with the perisporium of this connecting rod 12, promptly the outer wall of this connecting rod 12 is provided with the recess 121 that two compartment is opened vertically, and the middle hole wall 212 of this endoporus 21 forms two protuberances 213 in order to cooperate with this two recess 121, make to have the chimeric of multistage convex-concave between this connecting rod 12 and this handle endoporus 21, and play closely to connect this handle 2 and each elastic threads 11 end; The formation of this protuberance 213 makes the middle hole wall 212 of this endoporus 21 can further comprise one the 3rd aperture size again, and in the present embodiment, the aperture of this protuberance 213 is to equate approximately with first aperture size, but also can be bigger or smaller.

Referring to Fig. 3 and Fig. 4, in the present embodiment, this handle 2 generally is the C type by section the first housing 2a is with one second housing 2b is relative forms, each housing is made by plastic material, and has an inner face 24 that can dock, have relative axial slots 21a, 21b in this two inner face 24, after this two housing 2a, 2b butt joint, this two slotted eye 21a, 21b form the endoporus 21 of this handle; Form handle 2 relatively by this two housing 2a, 2b, make this handle endoporus 21 convenient to be assembled in outside the end of each elastic threads 11.Relatively be provided with detent 25 and protruding pin 26 again on this two inner face 24 and can provide screw 3 to penetrate sealed combined hole 27, make that this two housing can be in conjunction with fixing after forming handle 2.

The stay cord body-building device that constitutes according to the utility model on the implementation, as shown in Figure 5, user's both hands grip the wherein handle 2 at an elastic threads 11 two ends, and repeatedly stretch and this elastic threads of convergent-divergent, just can temper the effect of chest and arm muscle; And by the elastic threads 11 that the utlity model has plural different coefficient of elasticity, so, the different users can choose wherein an elastic threads 11 and implements according to oneself ability or hobby, and perhaps, same user also can choose the elastic threads 11 of different coefficient of elasticity progressively and come body-building.

Simultaneously, stay cord body-building device according to the utility model formation, can catch the end and the connecting rod 12 of each elastic threads 11 securely by this handle 2, make when arbitrary elastic threads 11 is subjected to axial tension, this elastic threads 11 and this handle 2 do not have the problem of disengaging, and can promote the security of using, so the utility model can have been reached the design effect of expection.

Aforementioned is the explanation of structure of the present utility model being done preferred embodiment, is can do multiple variation or modify embodiment and comply with design spirit of the present utility model; For example, the outer wall that shows this connecting rod 12 among the embodiment of Fig. 7 does not have the recess of setting, the outer wall that shows this connecting rod 12 in the embodiment of Fig. 8 can be provided with a recess 121 at both ends respectively, shows that in the embodiment of Fig. 9 the outer wall of this connecting rod 12 can be provided with a recess 121 in the centre position; Moreover middle hole wall 212 profiles of this endoporus 21 preferably match with the perisporium of this connecting rod 12, thereby this centre hole wall 212 can comprise a plurality of different aperture sizes.But those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
