Disclosure of Invention
The invention provides a body-building apparatus for tension exercise, which aims to solve the problem that no tension body-building apparatus matched with an intelligent body-building system exists in the prior art, and achieves the purposes of filling up the technical blank, reducing the volume of the tension body-building apparatus and meeting the use requirements of different users.
The invention is realized by the following technical scheme:
a body-building apparatus for tension exercise comprises two winders for winding and unwinding two groups of pull ropes, a resistance component for providing motion resistance for the pull ropes, a support arm assembly for allowing the pull ropes to pass through, and an adjusting component for adjusting the angle of the support arm assembly.
Aiming at the problem that a pull-force body-building apparatus matched with an intelligent body-building system does not exist in the prior art, the invention provides the body-building apparatus for pull exercise, wherein two wire winders are respectively used for winding and unwinding two groups of pull ropes so as to meet the requirement of simultaneously performing pull exercise by both hands of a user, and when the user pulls the pull ropes to perform exercise, motion resistance is provided through a resistance component; the support arm assembly is used for letting the stay cord pass, and the concrete mode of passing of stay cord does not belong to the protection scope of this scheme, and the technical personnel in the art can let the stay cord pass from the support arm assembly through arbitrary realizable mode according to actual demand. In addition, to the user of different heights or different use habits, the height of exerting oneself that suits respectively is different, the requirement to the support arm angle is different, consequently the angle of support arm assembly is still adjusted through adjusting part to this application to satisfy the user of different demands and normally carry out the pulling force and temper. When the pull rope is used, the pull rope is paid out from the winder, passes through the adjusting component after passing through the resistance component, enters the support arm assembly, finally penetrates out of the support arm assembly, and is directly or indirectly connected with a part for holding force application by a user. The application provides a pulling force body-building apparatus matched with an intelligent body-building system, and fills the blank in the prior art.
Furthermore, the resistance assembly comprises a double-shaft motor and a differential mechanism matched with the double-shaft motor, the two winders are respectively connected with two output ends of the double-shaft motor, the differential mechanism is arranged on the motor shell, and the differential mechanism is simultaneously matched with the two output ends of the double-shaft motor; the differential mechanism is used for enabling the rotating speeds of the two output ends to be equal. The differential structure used in the fitness equipment in the prior art is large in size and occupies space, the use requirements of gradual miniaturization and family of the fitness equipment cannot be met, and the differential structure is used in an intelligent fitness system, so that the whole system is large in size, difficult to accept by family users, and not beneficial to popularization and application. Therefore, the differential mechanism is integrally installed on the motor shell and is matched between the two output ends of the double-shaft motor, so that the defect of large size caused by the fact that the differential mechanism and the motor are arranged in a split mode and transmission is carried out in the traditional modes of a belt, a chain and the like in the prior art is overcome, the differential mechanism is significant to the miniaturization and the family development of the tension fitness equipment, is particularly suitable for an intelligent fitness system, can remarkably reduce the size of the intelligent fitness system, and is further beneficial to being accepted by family users.

In addition, if flexible connection modes such as belts and chains are adopted between the double-shaft motor and the differential, the connection structure is flexible and easy to deform, so that a user easily feels a force loss at the moment of applying the tensile force and at the moment of just loosening the tensile force, and the source of the force loss is the deformation or deformation recovery process of the flexible connection part. In the scheme, one bevel gear is meshed with the bevel gears on two sides at the same time, so that the rigidity of the whole transmission process is extremely high, the force-losing feeling can be weakened, and a better using effect can be obtained. In addition, installed part and motor housing fixed connection, the installed part rotates the piece for pivot and second and provides the installation station, pivot and installed part normal running fit to realize the second and rotate the free rotation of piece. Wherein fixed connection wire reel in the pivot for the stay cord that emits from the spooler bypasses, when making the stay cord by the person's of taking exercise pulling, its pulling force can drive the second and rotate a rotation.
