Embodiment 1

[0030] A sit-up training device for sports, such as Figure 1-4 As shown, it includes a bottom frame 1, a first guide carriage 2, a first support frame 3, a clamping mechanism 4 and a protective mechanism 5. The front and rear sides of the top of the bottom frame 1 are connected with the first guide carriage 2, and the two A first support frame 3 is slidably connected between the side first guide frames 2 , a clamping mechanism 4 is connected to the top left side of the bottom frame 1 , and a protection mechanism 5 is connected to the right end of the first support frame 3 .

[0031] The clamping mechanism 4 includes a top frame 41 , a second guide frame 42 , a first spring 43 , a clamping rod 44 , a clamping plate 45 , a first guiding plate 46 , a wedge clamping rod 47 and a second spring 48 . A top frame 41 is connected to the left side of the top, a second guide carriage 42 is connected to the top of the top frame 41, a clamping rod 44 is slidably connected to the second gu...

Embodiment 2

[0035] On the basis of Example 1, as Figure 5-6 As shown, it also includes a moving mechanism 6. The moving mechanism 6 includes a fixed frame 61, a low-speed biaxial motor 62, a rotating shaft 63, a first spur gear 64, a guide slider 65 and a first rack 66. The top of the bottom frame 1 A fixing frame 61 is connected on the right side, a low-speed biaxial motor 62 is installed on the fixing frame 61, a rotating shaft 63 is connected to the two output shafts of the low-speed biaxial motor 62, and the tail end of the rotating shaft 63 is connected with a first spur gear 64, A guide block 65 is connected to the top right side of a guide block 2, and a first rack 66 is slidably connected to the guide block 65. The first rack 66 meshes with the first spur gear 64 on the same side. The left end of the rack 66 is connected to the first support frame 3 .

[0036]When the first support frame 3 needs to be moved, the low-speed biaxial motor 62 is activated to drive the rotating shaft...

Embodiment 3

[0040] On the basis of Example 2, as Figure 5 and Figure 7 As shown, it also includes an overturning mechanism 8, the overturning mechanism 8 includes a cylinder 81, a second rack 82, a backing plate 83 and a second spur gear 84, and the front and rear sides of the first support frame 3 are connected with a cylinder 81. The telescopic rod of 81 is connected with a second rack 82, the top of the first support frame 3 is rotatably connected with a backing plate 83, and the front and rear sides of the backing plate 83 are connected with a second spur gear 84 through a shaft. The spur gear 84 meshes with the second rack 82 .

[0041] When people need to rest after exercising, the cylinder 81 can be shortened, the shortening of the cylinder 81 drives the second rack 82 to move to the right, and the second rack 82 moves to the right to drive the second spur gear 84 to rotate counterclockwise. The backing plate 83 rotates counterclockwise to support people. When people are suppor...
