[0024] like Figure 1-3 As shown, a sports training equipment for exercising the waist and abdomen includes a base 14, on which a first support frame 15 and a second support frame 13 are installed. The first support frame 15 is hingedly connected to a seat 8, and the second support frame 13 is installed with a cylinder 12. The output end of the cylinder 12 is hingedly connected to the seat 8. One end of the seat 8 is a foot end, and the other end is a head end. A controller is provided on the side wall of the seat 8, and the cylinder 12 is electrically connected to the controller. By adjusting the telescopic length of the cylinder 12, the inclination of the seat 8 can be adjusted. Normal users can keep the seat 8 in a horizontal state. For people who cannot do sit-ups or have difficulty doing them, the seat 8 can be adjusted to a state where the foot end is lower than the head end. For people who need higher intensity training, the head end can be adjusted to a state where the foot end is lower than the foot end. Athletes can adjust according to their own conditions. The controller is located on the side wall of the seat 8, and can be controlled when sitting on the seat 8 or lying on the seat 8. It is more convenient and easier to adjust the angle of the seat 8 to a position suitable for themselves.

[0025] A mounting frame 10 is installed at one end of the seat 8, and the mounting frame 10 is located at the foot end. An upper support rod 9 and a lower support rod 11 are installed on the mounting frame 10. The upper support rod 9 is located at a position obliquely above the lower support rod 11 on one side close to the seat 8. When doing sit-ups, the athlete can put his legs on the upper support rod 9, and then pass the calf through the middle of the upper support rod 9 and the lower support rod 11, and hook the lower support rod 11 with the instep, which can fix the legs and feet. The upper support rod 9 and the lower support rod 11 can be used for relay, and no other person is needed to help hold down his feet.

[0026] A counterweight slide rail 3 is installed at one end of the base 14, and a plurality of counterweight blocks 4 are slidably installed in the counterweight slide rail 3. The counterweight blocks 4 are provided with sliding holes, and a guide rail 1 is provided in the sliding hole. The guide rail 1 is slidably connected with the sliding hole, and the guide rail 1 serves to limit the moving trajectory of the counterweight blocks 4. The counterweight blocks 4 can move up and down in the vertical direction along the guide rail 1; a fixing hole 25 is provided on the side wall of the counterweight block 4, and a transmission rope 16 is connected to the top of the counterweight block 4, and one end of the transmission rope 16 is installed with a fixing hole 25. The matching latch 26 can be inserted into the fixed hole 25 on the side wall of the counterweight block 4, and can be inserted into the holes of different counterweight blocks to change the weight borne by the transmission rope 16, thereby meeting the training needs of different trainees. After the latch 26 on the transmission rope 16 is inserted into the corresponding counterweight block 4, when the transmission rope 16 performs corresponding lifting and lowering actions, the counterweight block 4 inserted with the latch 26 and the counterweight block 4 above it can move up and down in the vertical direction under the cooperation of the latch 26 and the guide rail 1.

[0027] A rope rack 17 is installed on the top of the counterweight slide rail 3, and the angle between the rope rack 17 and the counterweight slide rail 3 is 90°. The rope rack 17 is installed with a first fixed pulley 5, and the first fixed pulley 5 is located directly above the counterweight block 4. A third fixed pulley 6 is installed on the side of the rope rack 17 away from the first fixed pulley 5, and a second fixed pulley 2 is installed on the lower part of the outer wall of the counterweight slide rail 3.

[0028] The end of the transmission rope 16 away from the counterweight 4 passes through the first fixed pulley 5 and is fixedly connected to the screw structure 20. The third fixed pulley 6 is provided with an upper training rope 23. One end of the upper training rope 23 is provided with a divergent first handle 24. The end of the upper training rope 23 away from the first handle 24 is fixedly connected to the first threaded barrel 18 threadedly connected to the screw structure 20. The second fixed pulley 2 is provided with a lower training rope 21. The end of the lower training rope 21 away from the second handle 22 is fixedly connected to the second threaded barrel 19 threadedly connected to the screw structure 20.

[0029] When the screw structure 20 is connected to the second threaded cylinder 19, the transmission rope 16 is connected to the lower training rope 21. After selecting the appropriate counterweight, the human body lies horizontally on the seat 8, grabs the second handle 22 with both hands, and keeps both hands on a certain part of the body. Placing the hands in different positions can exercise the muscles and strength of different parts of the waist and abdomen. The legs are stuck with the upper support frame and the lower support frame 11, and sit-ups are performed. The gravity of the counterweight block 4 is transferred to the human body, and weighted sit-ups are performed, which can more effectively exercise the waist and abdominal strength.

[0030] When the screw structure 20 is connected to the first threaded tube 18, that is, the transmission rope 16 is connected to the upper training rope 23, after selecting the appropriate counterweight, the human body lies horizontally on the seat 8, grabs the first handle 24 with both hands, keeps both hands on a certain part of the body, and the legs are stuck with the upper support frame and the lower support frame 11, and do sit-ups. The gravity of the counterweight block 4 is transferred to the human body, and weighted sit-ups are performed, which can exercise the waist and abdominal muscles that cannot be efficiently exercised by doing sit-ups when the screw structure 20 is connected to the second threaded tube 19.

[0031] A limit strip is installed on the top edge of the seat 8, and a limit protrusion is provided on the inner wall of the limit strip. A buffer pad 7 is installed on the top of the seat 8, and a groove is installed on the buffer pad 7 to match the protrusion on the inner wall of the limit strip, so that the buffer pad 7 can be limited and connected to the limit strip, so that in normal practical process, the buffer pad 7 will not be easily separated from the limit strip due to the force of the person in the movement process. During use, many people will have strict requirements on the cleanliness of the equipment, because most people will produce a lot of sweat in the process of using the equipment, resulting in a lot of sweat stains on the buffer pad 7, affecting the normal use of the next person. The connection mode of the limit strip and the buffer pad 7 of the utility model is detachable, and the disassembly and assembly process can be completed by simply pulling and pressing. More buffer pads 7 can be prepared for the athlete to replace, so as to avoid the next person being unable to use it normally due to hygiene problems, and the buffer pad 7 can be designed with different thicknesses and different materials, which can be selected by the athlete, thereby improving the selectivity of the utility model during use and making the athletes more comfortable during exercise.

[0032] To sum up, in actual use, first choose a suitable cushion. If you need to do weighted sit-ups, first choose the training rope you need to use and connect it, choose a weight block of appropriate weight, then sit or lie down on the seat, and adjust the inclination angle of the seat by adjusting the telescopic length of the cylinder through the controller. After the adjustment is completed, lie on the seat, clamp your legs between the support rods, hold the corresponding handles with both hands, and place your hands in the appropriate position for sit-up training.

[0033] Therefore, the utility model realizes that the horizontality of the seat 8 can be adjusted by setting the first support frame 15, the second support frame 13, the cylinder 12 and the seat 8. People with different physiques can adjust the inclination angle of the seat 8 according to their own conditions to change their own exercise intensity. The counterweight block 4, the transmission rope 16, the fixed pulley and the training rope are provided, and the weight during sit-ups can be further adjusted to enhance the training intensity. The counterweight blocks 4 of different weights can be adjusted according to one's own exercise ability. The seat 8 is provided with a limit strip and a cushion pad 7. The athlete can replace the cushion pad 7 made of different materials or cleaned according to his or her own preferences during sit-ups, which can ensure the cleanliness of the cushion pad 7 and make the exercise process more comfortable. Such an exercise environment is very friendly to the athlete.

[0034] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model.
