     Please see  FIGS. 7-9 , the utility model provides a first embodiment of a trampoline with hanging seat units that allows elastic ropes to be mounted easily, and the trampoline with the hanging seat units that allows elastic ropes to be mounted easily comprises a frame  2 , a plurality of leg tubes  3 , a bouncing unit  4 , a plurality of hanging seat units  5 , and a plurality of elastic rope rings  6 . 
     The frame  2  comprises a space  21  and is in a hollow ring shape. 
     The leg tubes  3  are arranged at the bottom of the frame  2  at intervals. 
     Please see  FIGS. 8-10 , the bouncing unit  4  is located in the space  21  and connected and hung on the frame  2  and comprises a piece of bouncing cloth  41  and a plurality of connection belts  42  arranged on the periphery of the bouncing cloth  41  in a surrounding mode at intervals, and each connection belt  42  is in a closed ring shape. 
     The hanging seat units  5  are connected with the connection belts  42  respectively and each comprise a body  51 , a through groove  52  penetrating through the body  5  in the through groove direction L, a connection body  53  connected with the body  51  and adjacent to one end of the bouncing cloth  41 , an extension section  54  extending in the through groove direction L from the end, away from the bouncing cloth  41 , of the body  51 , a clamping and abutting section  55  extending towards the bouncing cloth  41  from the end, away from the body  51 , of the extension section  54 , a clamping space  56  defined by the body  51 , the extension section  54  and the clamping and abutting section  55  in cooperation, a through hole  57  penetrating through the body  51  in the through groove direction L, and a limiting component  58  penetrating through the through hole  57  to clamp and limit the corresponding elastic rope ring  6  in the clamping space  56  (as is shown in  FIG. 11 ), and each connection belt  42  penetrates through the corresponding through groove  52  and is tied on the corresponding connection body  53  in a sleeving mode. 
     The connection body  53  of each hanging seat unit  5  is provided with a first end part  531  and a second end part  532  which are formed at the two ends respectively, and the first end part  531  and the second end part  532  both stretch out of the body  51  and used for stopping and limiting the corresponding elastic rope ring  6 . 
     The side, away from the bouncing unit  4 , of the extension section  54  of each hanging seat unit  5  is provided with a concave arc surface  541 , and the curvature center of the concave arc surface  541  is away from the bouncing unit  4 . 
     Each elastic rope ring  6  is in a closed ring shape and connects the bouncing unit  4  with the corresponding hanging seat unit  5  around the frame  2 ; one end of each elastic rope ring  6  is arranged in the corresponding connection belt  42  in a sleeved mode and abuts against the corresponding connection body  53 , and the other end of each elastic rope ring  6  is clamped and fixed to the corresponding extension section  54  and the corresponding clamping and abutting section  55  and clamped and limited in the corresponding clamping space  56  through the corresponding limiting component  58  (as is shown in  FIG. 11 ). Each elastic rope ring  6  is in a closed ring shape, during manufacturing, the two tail ends of each elastic rope are connected, so that a protruding joint  61  is formed at the junction of each elastic rope ring  6 . 
     When the bouncing unit  4  is about to be mounted on the frame  2 , one end of one elastic rope ring  6  is tied on the connection belt  42  located between one hanging seat unit  5  and the bouncing cloth  41  in a sleeving mode from bottom to top firstly, and then the elastic rope ring  6  is stretched outwards, winds across the frame  2  from top to bottom and draws close to the space below the hanging seat unit  5 , wherein during stretching, it should be noticed that the end, close to the bouncing cloth  41 , of the elastic rope ring  6  is located between the first end part  531  and the second end part  532 , then the end, away from the bouncing cloth  41 , of the elastic rope ring  6  is arranged in the corresponding clamping space  56  in a sleeved mode and tied on the corresponding extension section  54  and the corresponding clamping and abutting section  55  in a sleeving mode, finally one limiting component  58  is made to penetrate through the corresponding through hole  57 , the end of the elastic rope ring  6  away from the bouncing cloth  41  is limited and clamped in the corresponding clamping space  56  (shown in  FIG. 11 ), and thus the elastic rope ring  6  is mounted; then the above steps are repeated until all the elastic rope rings  6  are mounted, and thus mounting is completed. 
     What should be mentioned is that the outward-stretching motion is conducted after the joint  61  formed on each elastic rope ring  6  is arranged below the bouncing cloth  41  during mounting (as is shown in  FIG. 10 ) so that the joints  61  can be hidden below the bouncing cloth  41 , and injuries to users are avoided when the trampoline is used. 
     Please see  FIG. 12 , a second embodiment of the utility model is different from the first embodiment in that each hanging seat unit  5  further comprises a stopper set  59  which is formed on the corresponding connection body  53  and used for stopping and limiting the corresponding elastic rope ring  6 ; each stopper set  59  is composed of two raised columns  591  which extend in the through groove direction L, wherein the raised columns  591  are adjacent to the first end part  531  and the second end part  532  respectively, and the extension direction of the raised columns  591  is opposite to the extension direction of the extension section  54 . During mounting, the above mounting method is adopted, however, it should be noticed that in the stretching process, the end, close to the bouncing cloth  41 , of each elastic rope ring  6  is located between the corresponding raised columns  591 , and thus the effect of limiting and clamping the elastic rope rings  6  can also be achieved. 
     Please see  FIG. 13 , a third embodiment of the utility model is different from the second embodiment in that each stopper set  59  is composed of two baffles  592  which extend outwards from the first end part  531  and the second end part  532  respectively, similarly, it also should be noticed that in the stretching process for mounting, the end, adjacent to the bouncing cloth  41 , of each elastic rope ring  6  is located between the corresponding baffles  592 , and thus the effect of limiting and clamping the elastic rope rings  6  can also be achieved. 
     In conclusion, the trampoline with the hanging seat units that allows elastic ropes to be mounted easily of the utility model has the following advantages that: 
     Firstly, both ends of each elastic rope  15  mentioned in the prior art are connected to the same fixing component  15 , and each fixing component  15  can be large in size and extremely thick; however, each hanging seat unit  5  in the utility model is only connected with one end of the corresponding elastic rope ring  6 , and thus each hanging seat unit  5  small in size and extremely thin and cannot protrude out of the surface of the bouncing cloth  41  after being mounted, and injuries to users are avoided. 
     Secondly, in the process of manufacturing the elastic rope rings  6 , only the two ends of each elastic rope need to be connected to form one joint  61 , and compared with the prior art, operation is easy and convenient; during mounting, outward-stretching motion is conducted after each joint  61  is arranged below the bouncing cloth  41 , so that the joints  61  are hidden below the bouncing cloth  41 , attractiveness is guaranteed, and injuries to users are avoided when the trampoline is used. 
     Thirdly, through the design of the first end part  531  and the second end part  532  of each connection body  53  and the raised columns  591  or the baffles  592  of each stopper set  59 , the end, adjacent to the bouncing cloth  41 , of each elastic rope ring  6  can be clamped and limited and be prevented from disengaging from the corresponding connection body  53 , and thus the safety in the using process is improved. 
     Fourthly, through the limiting components  58  which penetrate through the corresponding through holes  57  to clamp and limit the corresponding elastic rope rings  6  in the clamping spaces  56 , the end, away from the bouncing cloth  41 , of each elastic rope ring  6  can be clamped and limited and be prevented from disengaging from the clamping space  56 , so that the safety in the using process is improved, and the purposes of the utility model can be realized truly. 
     In conclusion, the foregoing descriptions are only embodiments of the utility model, however, the scope of the utility mode is not limited to the foregoing description, and all simple equivalent changes and modifications made according to the scope of the claims and the content of the description of the utility model are still within the scope of the utility model.
