Example 1

Cooperation figure 1 to fig. 6 are shown, the utility model discloses a multi-functional fitness equipment aims at providing a simple structure, reasonable in design, simultaneously small, convenient to use's multi-functional fitness equipment, and this application multi-functional fitness equipment mainly can be used to squat deeply and be good for the abdomen training, and also usable this fitness equipment excavates other more body-building functions certainly, does not do the restriction here.

With reference to fig. 1 to 6, a multifunctional exercise device comprises an underframe 10 and a vertical frame 20 disposed on the underframe 10, wherein a lifting assembly 30 is disposed on the vertical frame 20, a seat 35 is disposed on the lifting assembly 30, the lifting assembly 30 is connected to the vertical frame 20 through an elastic member 50, and the elastic member 50 makes the lifting assembly 30 have a tendency of moving upward,

the rotary frame 40 is arranged on the vertical frame 20, the middle part of the rotary frame 40 is rotatably connected with the vertical frame 20, the bottom end of the rotary frame 40 is connected with the bottom frame 10 through an elastic piece 50, and the elastic piece 50 enables the top end of the rotary frame 40 to have a tendency of upward rotation.

The multifunctional body builder is mainly used for abdomen building training of a deep squatting machine. As shown in fig. 5 to 6, when performing deep squat training, a person sits on the seat cushion 35 to squat down and then stands up, the seat cushion 35 automatically rises under the action of the elastic member 50, and continuously squat down and stand up to realize deep squat training, and the elastic member 50 automatically rises and resets the seat cushion 35 to provide auxiliary force for the trainee to stand up;

with reference to fig. 3 to 4, when doing abdominal exercise training (actually, rolling abdomen or sit-up training), a person sits on the seat cushion 35, the person can sit on the seat cushion 35 backwards and downwards in a supine posture to press down the top end of the rotary frame 40, so that the whole rotary frame 40 rotates, then the person sits up, the top end of the rotary frame 40 rotates upwards and forwards under the action of the elastic element 50 to reset, and the person sits up and continuously sits up, thereby achieving abdominal exercise training, the elastic element 50 realizes automatic upwards rotation and reset of the rotary frame 40, and providing auxiliary force for the trainee to sit up.

This multi-functional fitness equipment through setting up elastic component 50, provides the auxiliary force for the training person in the training process for even be beginner or rely on the unable people who squats deeply of self strength and the training of strong abdomen, also can easily accomplish corresponding action, still can guarantee certain efficiency simultaneously, obtain better training effect. Meanwhile, due to the detachable design of the elastic pieces 50, the number of the elastic pieces can be rotated according to the self requirements during use, the corresponding auxiliary force is changed accordingly, and the use is flexible and convenient.

The specific structure of the rotating frame 40 is as follows: the rotary frame 40 is in a shape of 'T', the middle part of the rotary frame is positioned at the front side, the middle part divides the rotary frame 40 into an upper leaning frame 41 and a lower rotary frame 42, the bottom end of the lower rotary frame 42 is connected with the rear end of the bottom frame 10 through an elastic piece 50, and a limiting cross rod 22 is respectively arranged at the front side and the rear side of the lower rotary frame 42. When the upper leaning frame 41 is pressed downward and rotated backward, the corresponding lower rotating frame 42 is rotated forward and upward, and then the elastic member 50 is stretched, and when the pressure of pressing the lower leaning frame 41 is eliminated, the elastic member 50 pulls the lower rotating frame 42 and the upper leaning frame 41 to reset. In addition, two spacing horizontal poles 22 all extend the setting about, and all set up on grudging post 20, when swivel mount 40 was rotatory, when lower swivel mount 42 offseted with two spacing horizontal poles 22 respectively, reached swivel mount 40's rotation limit promptly. Research shows that the abdomen of the human body can be trained well within the range of 45-85 degrees of backward bending, and meanwhile, the upper leaning frame 41 is always in the angle range through the limitation of the limiting cross bar 22, so that the corresponding human body can obtain a good training effect when doing abdomen-building training.
