Active force when making Calf muscle obtain stretching while abdominal muscles, while stretching rotation using Calf muscle will use
The back of person jacks up, and user is helped to complete movement of drawing the abdomen, and tempers basic or figure obesity user suitable for zero and lies on the back receipts
Abdomen can satisfy the market demand, be suitble to promote.Using present apparatus initial stage, the first all bullets is made by safety hook 19 first
The other end of spring 18 is separated with link 16, and user lies in the top side of arc panel 1, and the curved top for riding over leg rod 4 of leg is double-legged
Instep catches on hook foot lever 13, lies on the back when drawing the abdomen, and the abdomen of user is firmly drawn the abdomen, while thigh firmly turns shank clockwise
Dynamic, instep drives hook foot lever 13, first connecting rod 12, square bar 7 to rotate along the axis of square bar 7, and square bar 7 drives 8 turns of the first helical gear
Dynamic, the first helical gear 8 engages cooperation with the second helical gear 20, and the second helical gear drives third helical gear 24 by the first horizontal axis 21
Rotation, third helical gear 24 engage cooperation with the 4th helical gear 26, and the 4th helical gear 26 is by the second horizontal axis 25 with moving gear 29
Rotation, gear 29 engage cooperation with bar tooth socket 34, and gear 29 is complete gear, and slide bar 32 slides obliquely along inclined tube 30,
Slide bar 32 drives arc pallet 37 to move obliquely, and arc pallet 37 jacks up the back of user, and user is helped to complete to face upward
Sleeping to draw the abdomen, when arc pallet 37 moves obliquely, arc pallet 37 is rotated along with the articulated shaft of slide bar 32, makes arc pallet 37
Top side and the back of user keep fit-state, until the leg of user is stretched, the upper body of user and leg form right angle,
Calf muscle is stretched, shank is then put down, user slowly lies down again, and arc pallet 37 is by pressure obliquely
Power, slide bar 32 reenter in inclined tube 30, and above process inverted sequence carries out, until arc pallet 37 enters in deep gouge 36, first connecting rod
12 reset, and complete abdomen-in exercise of once lying on the back, and thigh drives shank movement in movement, while abdominal muscles obtain training,
Leg muscle is also taken exercise；When user abdominal muscles have certain strength after, user lies on the back draw the abdomen during to arc
The dependence of shape supporting plate 37 is gradually reduced, and the leg power used is gradually reduced, and makes the another of the first spring 18 by safety hook 19
One end is connect with link 16, and when first connecting rod 12 rotates clockwise, first connecting rod 12 passes through second connecting rod 14,15 band of third connecting rod
Dynamic link 16 rotates, and corresponding first spring 18 is made to be stretched, and by increasing the quantity of the first spring 18, increases first connecting rod 12
Required active force when rotation makes leg muscle obtain varying strength to increase strength needed for thigh drives shank rotation
Exercise；It is continuously increased, is assisted when user does not need arc pallet 37, only just by abdomen strength with the abdomen strength of user
Can complete to lie on the back abdomen-in exercise when, rotate in an anti-clockwise direction bolt 10, bolt 10 drives 8 edge of the first helical gear by change 11
Square bar 7 moves forward, and the first helical gear 8 is separated with the second helical gear 20, only makes hook foot lever 13 by the pulling force of the first spring 18
Resistance is formed to instep moving direction.
Specifically, as shown, the top side of screw 9 described in the present embodiment opens up first through hole 39, the top of bolt 10
Side corresponds to first through hole 39 and opens up blind hole 40, and activity installation inserted link 41 in first through hole 39, the lower end of inserted link 41 is located at blind hole 40
Interior, inserted link 41 is fixedly connected with the top side of screw 9 by being set in the second spring 42 of 41 periphery of inserted link.It inserts the lower end of inserted link 41
Enter in blind hole 40, can be avoided bolt 10 and rotated in screw 9, the first helical gear 8 is made to keep engaging matching with the second helical gear 20
It closes, being drawn onto for inserted link 41 is extracted out of blind hole 40, it just being capable of rotating bolt 10.
Specifically, as shown, handle 43 is fixedly mounted in the front end of bolt 10 described in the present embodiment.Pass through 43 turns of handle
Dynamic bolt 10 is more laborsaving, increases user's usage experience.
Further, as shown, vertical bar 3 described in the present embodiment is Telescopic rod structure, and Telescopic rod structure has certainly
Locking device.Can up and down adjustment take the height of leg rod 4, and take and can be taken by self-locking device fixation after the height adjustment of leg rod 4
Leg rod 4 makes the present apparatus can adapt to the user of different lower-leg lengths, increases the applicability of the present apparatus.
Further, as shown, the top side of arc pallet 37 described in the present embodiment covers one layer of emulsion layer 44.Increase
The comfort for adding 37 top side of arc pallet avoids annular supporting plate 37 that the back of user is injured when holding up the back of user.
Further, as shown, the middle part in 12 outside of first connecting rod described in the present embodiment opens up second respectively and leads to
Hole 45, the front side of rectangular frame 5 the second through-hole 45 corresponding with rear side open up threaded hole 46, activity respectively in the second through-hole 45 respectively
Butterfly bolt 47 is installed, butterfly bolt 47 can be threadedly coupled with corresponding threaded hole 46 respectively to be cooperated.Butterfly bolt 47 and spiral shell
When pit 46 is threadedly engaged, first connecting rod 12 can not be rotated, and fix 13 position of hook foot lever, the foot of user is unable to drive hook foot
Bar 13 is rotated along the axis of square bar 7.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
