DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0021] Embodiment one

[0022] Please refer to Figures 1-5The embodiment provides an eccentric fitness support arm, which comprises a rotating ball head 101, a support arm pipe body 102, a support arm pitch rotation center 505 and a rope pulley 506. The rotating ball head 101 is mounted at the end of the support arm pipe body 102 through two bearings, so that the rotating ball head 101 can rotate around the center line of the support arm pipe body 102 by 360 degrees. Two rope pulleys are arranged in the rotating ball head 101. When a fitness exercise is performed, a pulling rope 508 is led out from between the two rope pulleys arranged in the rotating ball head 101 through the inside of the support arm pipe body 102, so that the pulling rope 508 supports all azimuth angle strength training. The support arm pipe body 102 is integrally connected with a support arm pitch rotation disc 104. The support arm pitch rotation disc 104 can rotate around the support arm pitch rotation center 505 to realize pitch angle adjustment of the fitness support arm. The extension line of the center line of the support arm pipe body 102 is eccentrically arranged with the support arm pitch rotation center 505, that is, the two do not coincide. The extension line of the center line of the support arm pipe body 102 is eccentrically arranged with the support arm pitch rotation center 505 by an end distance. The asymmetric eccentric design leaves a design space for the arrangement of a fitness support arm pitch rotation locking mechanism, so that the fitness support arm pitch rotation locking mechanism is simple and reliable and low in cost. A pair of pitch adjustment toothed discs 302 are arranged in the inside of the support arm pitch rotation disc 104. A rope pulley 506 is arranged in the middle of the two pitch adjustment toothed discs 302. The pulling rope 508 is guided through the rope pulley 506 to realize turning. The rope pulley 506 rotates around the support arm pitch rotation center 505. The columnar structure member extended downward from the pitch adjustment toothed disc 302 is embedded in a support arm left-right rotation seat 105. The two are gap-fitted to realize left-right rotation movement. The columnar structure member extended downward from the pitch adjustment toothed disc 302, the pitch adjustment toothed disc 302 and a left-right adjustment toothed disc 303 are integrally arranged. The support arm left-right rotation seat 105, a support arm mounting seat body 501 and a mounting flange 107 are integrally arranged. The complete fitness support arm assembly is fixed to the whole fitness equipment through the mounting flange 107.

[0023] The arm pipe body 102 is a hollow tubular structure, and an inner layer arm pipe body 802 is arranged in the inner layer of the arm pipe body 102. The inner layer arm pipe body 802 can realize telescopic movement relative to the arm pipe body 102 through pulling operation, so as to realize telescopic operation of the length of the overall fitness arm. The inner layer arm pipe body 802 after extension can be locked by a button lock, so that the movement range of the fitness arm is longer and larger, especially when high position pulling training is performed, such as high position pull-down back training. The inner layer arm pipe body 802 after retraction is completely hidden in the inner layer of the arm pipe body 102. The two layers of pipe arms are isolated by a nylon sleeve. The nylon sleeve is arranged in the inner layer of the end of the arm pipe body 102. One end of the inner layer arm pipe body 802 is also provided with a nylon end head. During the pulling movement of the two layers of pipes, the nylon sleeve and the nylon end head play the roles of friction lubrication and positioning.

[0024] The eccentric fitness arm further comprises a pitch adjusting handle 103, a pitch adjusting tooth disc 302 and a pitch adjusting tooth pin 308. The pitch angle adjustment of the eccentric fitness arm is realized by cooperation of the pitch adjusting tooth disc 302 and the pitch adjusting tooth pin 308. The pitch adjusting handle 103 and the pitch adjusting tooth pin 308 are fixedly connected. A user pulls the pitch adjusting handle 103 to drive the pitch adjusting tooth pin 308 to be separated from the tooth groove of the pitch adjusting tooth disc 302, so as to realize pitch angle unlocking operation of the fitness arm. A spring is arranged at the connection position of the pitch adjusting handle 103 and the pitch adjusting tooth pin 308. When the user does not pull the pitch adjusting handle 103, the spring automatically presses the pitch adjusting tooth pin 308 into the tooth groove of the pitch adjusting tooth disc 302, so as to realize pitch angle locking operation of the fitness arm. The pitch adjusting tooth pin 308 can slide forward and backward in the activity groove. The extension line of the sliding path of the pitch adjusting tooth pin 308 coincides with the pitch rotation center 505 of the arm, that is, the pitch adjusting tooth pin 308 needs to slide opposite to the pitch adjusting tooth disc 302 to realize simple and reliable locking and unlocking operation.
