Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution：Trick stretches sit-ups structure, including chair body 1, chair body 1 includes the first backup plate 12 and the second backup plate 16, and the top movable of the first backup plate 12 is connected with leg pressing part 2, and first leans on The right end of plate 12 is fixedly connected with the second backup plate 16, and the left and right sides and top of the second backup plate 16 are provided with fixed ring 18, The outside of fixed ring 18 is fixedly connected with pull ring 3, and pull ring 3 is fixedly connected with drawing 31 by outer end.

In the utility model：It is detachably connected between leg pressing part 2 and the first backup plate 12.

In the utility model：Pull ring 3 is made of the strong material of toughness.

In the utility model：It draws and is made 31 of rubber material.

In the utility model：First backup plate 12 is all made of cotton filling with the second backup plate 16 and is made.

Working principle：Both hands are pulled up the application method of movement：Pull ring 3 is mounted at the top of the chair back, leg pressing part 2 is fixed On seat surface.Both hands are pulled up after holding, and are provided resistance by pull ring 3, while being fixed both legs by leg pressing part 2, are preferably forged Refine both arms, the application method of the upward stretching routine of both hands：Pull ring 3 is mounted on chair back two sides, leg pressing part 2 is fixed on seat surface, Both hands stretch out after holding, and provide resistance by pull ring 3, while being fixed both legs by leg pressing part 2, preferably exercise both arms, pedal The application method of leg movement：Back and seat surface are inverted recoil and leaning on back, pull ring 3 is mounted on the top or two of the chair back Side, both feet are inserted in pull ring 3, provide resistance, both legs leg kicking sport forward, the application method of sit-up movement by pull ring 3：It will pressure Leg piece 2, which is mounted on seat surface, fixes both legs, then after the chair back is laid flat, and carries out sit-up movement.

In summary：The trick stretches sit-ups structure, is improved on the basis of general and formula chair, not by two kinds With usage mode, can complete that " movement of both hands extending transversely ", " both hands stretch upwards under the premise of having the auxiliary and protection of chair Movement ", " leg kicking sport " and " sit-ups ", meanwhile, have both storage function, when not in use, pack and transportational process In, packed and transported volume is greatly reduced, transportation cost and storage space are reduced.
