Title: Flying ring for fitness exercise and a training apparatus including the same

Description:
CROSS REFERENCE TO THE RELATED APPLICATIONS 
     This application is based upon and claims priority to Chinese Patent Application No. 202022455814.8, filed on Oct. 29, 2020, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to the technical field of flying rings, and more particularly, to a flying ring for fitness exercise and a training apparatus including the same. 
     BACKGROUND 
     Chinese Patent No. 201220484645.3 discloses a length-adjustable flying ring for fitness exercise, which includes a nylon rope fixed on a tall object. One end of the nylon rope passes through a buckle ring and is fixed inside a movable buckle, and the other end of the nylon rope passes through the movable buckle and is fixedly connected to a flying ring grip. The nylon rope is attached to the flying ring grip by screws. This flying ring for fitness exercise is light, user-friendly, and is apt to use in various fitness facilities. Additionally, the flying ring grip has a simple structure and an adjustable height, which is easy to operate. 
     The aforementioned patent can solve the corresponding technical problems but still has the following shortcomings. 
     The flying ring for fitness exercise cannot be suspended since it lacks a component that allows the flying ring to be connected to an external belt. This causes an inconvenience to the user when exercising. 
     The training apparatus only has one ring body and thus is insufficient to meet the requirements for supporting the feet or hands of the human body. Additionally, the ring body cannot be installed on the belt, and therefore is awkward to store the ring body properly. The belt cannot be wound around an object for suspending, which limits how the human body can exercise and limits to where it can be used, like in particular exercise facilities only.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The present invention is further described with reference to the drawings and specific embodiments. 
     Referring to  FIGS. 1-15 , the present embodiment adopts the following technical solutions. 
     A training apparatus includes two ring bodies  1  for supporting the feet or hands of the human body and the belt  2 . The ring bodies  1  are detachably arranged at both ends of the belt  2  through a connecting device. The connecting device includes the adjusting frame  3  that is arranged on the ring body  1  and configured for the belt  2  to pass therethrough, and the limiting rod  4  that is movably arranged on the adjusting frame  3  and configured to limit the belt  2  with an adjusted length. Each of both sides of the limiting rod  4  is provided with the U-shaped sliding groove  5  or the sliding protrusion  6 , and the limiting rod  4  is slidably arranged on the adjusting frame  3  through the U-shaped sliding groove  5  or the sliding protrusion  6  on both sides. The limiting rod  4  is provided with limiting teeth  7  for retaining the adjusted belt  2 . The lower part of the adjusting frame  3  is threadedly connected to the upper part of the ring body  1  through the bolt  8 , and the bolt  8  is mated with a nut (not shown). Each of the ends of the belt  2  is bent to form the limiting end  9 , and the limiting end  9  is sewn with the belt  2 . The clamping edge  10  for clamping the upper part of the adjusting frame  3  is formed between the end of the limiting end  9  and the belt  2 . A supporting device for supporting the feet or hands of the exerciser is detachably arranged on the inner ring of the ring body  1 . The supporting device includes the supporting plate  11  for supporting the feet or hands of the human body, and the supporting plate  11  is provided with the clamping part  12  connected to the inner ring of the ring body  1 . Each of the left side, the right side and the lower side of the supporting plate  11  is provided with the clamping part  12 . The anti-slip part  13  is provided on the surface of the supporting plate  11 . The supporting plate  11  is a flat plate or a downwardly concave arc-shaped supporting plate or an upwardly convex arc-shaped supporting plate. 
     The working principle of the present invention is as follows. One of the ring bodies  1  is connected to one end of the belt  2 , and the adjusting frame  3  is threadedly connected to the upper part of the ring body  1  through the bolt  8 . The supporting plate  11  is installed on the inner ring of the ring body  1  through the clamping part  12 , and the limiting rod  4  is moved upward to the highest point through the U-shaped sliding groove  5  or the sliding protrusion  6 . One end of the belt  2  passes through the opening between the lower part of the limiting rod  4  and the adjusting frame  3 , and then the limiting rod  4  is moved downward a certain height through the U-shaped sliding groove  5  or the sliding protrusion  6 . One end of the belt  2  passes through the opening between the upper part of the limiting rod  4  and the adjusting frame  3  in the reverse direction, and the passed length of the belt  2  is adjusted. Then, the limiting rod  4  is moved upward through the U-shaped sliding groove  5  or the sliding protrusion  6  to limit one end of the belt  2 . The limiting teeth  7  on the limiting rod  4  retain the adjusted belt  2 , and the limiting end  9  cooperates with the clamping edge  10  to clamp the upper part of the adjusting frame  3 . The corresponding installation of the other ring body  1  is similar in principle to the above.
