Detailed Description

The following description of the preferred embodiments of the present invention will be provided with reference to the accompanying drawings, so that the advantages and features of the present invention can be easily understood by those skilled in the art, and the scope of the present invention can be clearly and clearly defined.

Referring to fig. 1 to 4, the stretch cord in this embodiment includes a handle assembly 1, a stretch cord 3, a fixed pulley assembly 2, and a cord adjusting assembly 4; the rope adjusting assembly 4 comprises an adjusting buckle 41 and a fixing piece 42 arranged in parallel with the threading direction of the adjusting buckle 41, and the adjusting buckle 41 and the fixing piece 42 are fixedly connected and move synchronously; one end of the elastic pull rope 3 sequentially penetrates through the adjusting buckle 41 and the fixed pulley component 2 and is connected with the fixing component 42, the elastic pull rope 3 is made of a latex tube, when the elastic pull rope 3 is in a loosening state, the tension on the elastic pull rope 3 is zero, the friction between the adjusting buckle 41 and the elastic pull rope 3 can be ignored at the moment, the elastic pull rope 3 can smoothly move in the adjusting buckle 41, the length of the elastic pull rope 3 between the adjusting buckle 41 and the fixing component 42 is adjusted, the elastic pull rope 3 between the adjusting buckle 41 and the fixing component 42 is shortened, the usable overall length of the elastic pull rope is corresponding in side length, requirements of fitness users with different heights and different actions on the initial length and the stroke can be met, the elastic pull rope 3 can be moved only by pulling the skipping rope component 4 during the adjusting action, and the operation is simple, convenient and rapid.

One end of the elastic pull rope 3 is connected with the handle component 1 through the fixed pulley component 2, the other end of the elastic pull rope is a fixed handle, and one end of the elastic pull rope 3 can adjust the length of the elastic pull rope through the fixed pulley component 2.

One end of the elastic stay cord 3 is connected with the handle component 1 through the fixed pulley component 2, and the other end of the elastic stay cord is arranged to be a handle end with the same structure as the fixed pulley component 2 and the handle component 1, so that the length of the elastic stay cord 3 can be adjusted at two ends of the elastic stay cord 3, the length adjusting range of the elastic stay cord 3 is expanded, and the practicability of the elastic stay cord 3 is further improved.

Referring to fig. 4, the fixed pulley assembly 2 includes a support 22 and a fixed shaft 23, a sliding through hole 24 for the elastic cord 3 to slide is formed between the support 22 and the fixed shaft 23, and when the elastic cord 3 is located in the sliding through hole 24, a gap is also formed between the elastic cord 3 and a hole wall of the sliding through hole 24, so that smoothness when the elastic cord 3 is pulled to adjust the length is ensured, and the adjustment time of a body builder is saved.

The contact surface of the fixed shaft 23 and the elastic pull rope 3 is an arc surface, so that the elastic pull rope 3 can not generate interference when sliding in the fixed pulley component 2, and the efficiency of adjusting the length of the elastic pull rope 3 by a body builder is improved.

The one end that fixed pulley assembly 2 kept away from fixed axle 23 is provided with one with elasticity stay cord 3 with the bar spread groove 21 that handle component 1 is connected, the both ends of elasticity stay cord 3 all are provided with a handle component 1 through fixed pulley assembly 2, and the person of being convenient for promotes body-building and stimulates elasticity stay cord 3 to take exercise, improves body-building person's use and experiences.

The handle assembly 1 comprises a handle 101 and a protective sleeve 102 coated on the surface of the handle 101, the protective sleeve 102 is arranged to prevent the hands of a body builder from being damaged in the using process, and meanwhile, the service life of the handle 101 can be prolonged; handle 101 pass through the meshbelt 103 with bar spread groove 21 swing joint on the fixed pulley assembly 2, handle 101 is inside to be seted up along its length direction and is supplied the perforation 104 that meshbelt 103 penetrated, through setting up handle 101, the person of being convenient for promotes body-building and stimulates elasticity stay cord 3 and take exercise, improves body-building person's use and experiences.

Referring to the accompanying drawings 1 to 2, anti-slip threads 43 are arranged on two sides of the length direction of the rope adjusting assembly 4, the adjusting buckle 41 is specifically a herringbone buckle, the anti-slip threads 43 are arranged on the rope adjusting assembly 4, so that a worker can conveniently pull the rope adjusting assembly 4 to adjust the length of the elastic pull rope 3, and the phenomenon that the rope adjusting assembly 4 is out of hand when being pulled is avoided.

A pull rope insertion through hole 421 is formed in the fixing part 42 along the length direction of the fixing part, the hole diameter of the insertion end of the pull rope insertion through hole 421 is smaller than the hole diameter of the end, far away from the elastic pull rope 3, of the pull rope, after the elastic pull rope 3 is inserted into the fixing part 42, the elastic pull rope 3 can be prevented from being separated from the fixing part 42 in a rope knotting mode, the larger hole diameter of the end, far away from the elastic pull rope 3, can accommodate a larger rope knot, and therefore the elastic pull rope can not fall off from the small hole diameter of the insertion end.

The working principle is as follows: the two ends of the elastic pull rope 3 respectively penetrate through the adjusting buckle 41 on the rope adjusting component 4 and the fixed pulley component 2 in sequence and are finally fixed with the fixing component 42 on the adjusting component, when the elastic pull rope 3 penetrates through the adjusting buckle 41, the elastic pull rope 3 forms a certain angle with the pulling direction during pulling, and under a tensioning state, pressure perpendicular to the elastic pull rope 3 can be formed to form friction force (the friction force and the pulling force are in direct proportion to the common knowledge), and at the moment, the position of the elastic pull rope 3 with the adjusted length can not move any more, so that the length of the elastic pull rope 3 is locked; when the elastic stay cord 3 is loosened, the tension on the elastic stay cord 3 is zero, the friction between the adjusting buckle 41 and the elastic stay cord 3 can be neglected at the moment, the elastic stay cord 3 can smoothly move in the adjusting buckle 41, the length of the elastic stay cord 3 can be conveniently adjusted, meanwhile, both ends of the elastic stay cord 3 can be adjusted, and the practicability of the elastic stay cord 3 is effectively improved.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the above embodiments is to let the person skilled in the art understand the contents of the present invention and implement the present invention, which can not limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
