The seat cushion 6 is made of softer rubber material. The front end of the rear bracket 4 is inserted into the front bracket 3 through the first through groove 31. A telescopic structure 5 is provided at the front end of the rear bracket 4. The front end of the telescopic structure 5 passes through the front bracket 3 and the front support seat 1 respectively. Slide blocks 42 that slide with the side sliding grooves 32 are provided on the left and right sides of the front end of the rear bracket 4. A supporting structure 7 is provided on the top of the rear support seat 2. The top front end of the supporting structure 7 extends forward to the back of the seat cushion 6.
[0018] Footrests 11 are rotatably provided on the left and right ends of the front support seat 1 facing the rear support seat 2. Anti-slip rubber sleeves 12 are sleeved on the left and right sides of the front support seat 1 and the rear support seat 2. Pulleys 63 corresponding to the rotating shaft 13 are inserted on the left and right sides of the bottom of the seat cushion frame 62.
[0019] The telescopic structure 5 includes a hook screw 51, a nut 52, a first elastic rope 54 and a hook head 55. The hook screw 51 is inserted into the first through slot 31 in the front bracket 3 and passes through the front end of the front support seat 1 forward. The nut 52 is sleeved on the rear end of the hook screw 51 and is located in the first through slot 31. The hook head 55 is arranged at the front end of the rear bracket 4. The top of the hook head 55 and the hook screw 51 are both provided with grooves 53 for accommodating the first elastic rope 54. The two ends of the first elastic rope 54 are respectively inserted into the grooves 53.
[0020] The supporting structure 7 includes a connecting rod 73, a push rod 77, two supporting frames 71, two second elastic ropes 74, two storage rods 75 and a plurality of limiting hoops 76. The tops of the two supporting frames 71 are respectively rotatably connected to the left and right sides of the rear supporting seat 2. The front ends of the two supporting frames 71 are provided with a clamping groove 72 for storing the connecting rod 73. The left and right ends of the storage rod 75 are inserted into the clamping groove 72. The two ends of the push rod 77 are rotatably connected to the tops of the two supporting frames 71, and the push rod 77 is in contact with the back of the seat cushion 6. The two storage rods 75 are arranged on the left and right sides of the rear side of the rear bracket 4. The plurality of limiting hoops 76 are respectively correspondingly sleeved on the surface of the storage rod 75. One end of the two second elastic ropes 74 is respectively sleeved on the surface of the storage rod 75, and the other end of the two second elastic ropes 74 is sleeved on the surface of the connecting rod 73.
[0021] The principle of the utility model is that when the entire structure is not in use, the front bracket 3 and the rear bracket 4 can be retracted to reduce the floor space, thereby facilitating the storage of the device.
[0022] When it is necessary to exercise, the front support seat 1 is slightly lifted and then pulled forward, so that the side slide grooves 32 on the left and right sides of the front bracket 3 are limited by the slider 42 at the front end of the rear bracket 4 and stretched forward until they are stretched to the maximum range of the two. Then the front support seat 1 is placed on the ground to complete the initial fixation of the structure. At this time, the person sits on the seat cushion 6 with both feet 11 on the two front footrests 11. At this time, the person supports the ground with both hands or hugs the chest, and slowly applies pressure backward with the waist of the person, so that the back of the seat cushion 6 applies pressure backward on the push rod 77. Connecting rods 73 are inserted in the support frames 71 on both sides of the push rod 77, and second elastic ropes 74 are sleeved on the front ends of both sides of the connecting rod 73, and the second elastic ropes 74 are sleeved with the storage rods 75 arranged on both sides of the rear bracket 4. When the support frame 71 is pushed backward by the push rod 77, the second elastic ropes 74 will be pulled forward to reset the entire support structure 7, thereby helping the person to exercise.
[0023] When exercising the legs at this time, the pulley 63 located under the seat cushion frame 62 is removed and inserted into the rotating shaft 13 on both sides of the front support seat 1. The bottom of the pulley 63 contacts the ground to facilitate the forward and backward sliding of the entire front support seat 1. Then adjust the position of the hook screw 51 in the front bracket 3 and limit it through the nut 52. The front end of the hook screw 51 can be fine-tuned forward and backward in the first through groove 31, so as to control the distance between the first elastic rope 54 and the rear hook head 55, so as to achieve the pulling force during exercise. Then the person sits on the seat cushion 6, steps forward with both feet on the foot pedal 11, and applies pressure to the pedal forward and backward to push it, so as to exercise the legs.
[0024] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
