The specific embodiment

See also Fig. 3, the utility model comprises lie pad 21, one support 3, a sleeve 41 and a support bar 51.This pad 21 of lying can be for couching, and this support 3 constitutes herringbone by a vertical rod 31 before one and an oblique fulcrum bar 32 and is located at the pad 21 times of lying.Plurality of receptacles 311 is established in oblique fulcrum bar 31 sides, and the front end of the pad 21 of lying is supported in the front end of oblique fulcrum bar 31, and the rear end of the pad 21 of lying then mat support bar 51 is supported on the oblique fulcrum bar 31.This sleeve 41 is sheathed on this oblique fulcrum bar 31 slidably, and sleeve 4 upper ends and this support bar 51 articulate.Oblique fulcrum bar 31 is square tubes, and sleeve 4 is square tubes of a cutting back.Each combines a base bar 312 to stablize fitness equipment preceding vertical rod 32 and oblique fulcrum bar 31 and ground contact jaw.For the fixing of user's lower limb is provided, respectively establish a cross bar 321,322 up and down in preceding vertical rod 32, cross tube 321 supports for knee joint, and sheer pole 322 colludes for instep and leans on, and it is comfortable for using to coat elastomeric material around the bar.

Please consult Fig. 4, Fig. 5 and Fig. 6 again, sleeve 4 is established a perforation 41 in the homonymy of jack 311.One end of the tip bar 42 of one sheathed back-moving spring 43 is through a connecting support 44, and this connecting support 44 can screw togather with perforation 41, and making and pulling out tip bar 42 is displaceable sleeve 4, decontrols tip bar 42 and inserts in the jack 311 fixing spacing again again.Tip bar 42 outsides are established the big jaw stick 45 that rises and are convenient to hold and draw, and restriction tip bar 42 reciprocating positions, and mat is sheathed on back-moving spring 43 compressions between the groove 441 of the bead 421 of tip bar 42 and connecting support 44 or resilience with mobile tip bar 42.Therefore, as shown in Figure 7, when sleeve 4 is displaced on the oblique fulcrum bar 31, can change the angle that combines of support bar 51 and oblique fulcrum bar 31, and then can be with user's hobby adjustment the lie position and the angle of pad 21.

Fitness equipment support angle of the present utility model is adjusted structure except that the adjustment that can be applicable to the sit-ups frame, also can be applicable to other similar indoor body-building utensil with the guiding mechanism as pad (or seat cushion) support angle of lying.

Therefore, the utlity model has following advantage:

1, support angle regulating structure for body-building device of the present utility model can by the tip bar of sheathed back-moving spring Pull out easily the tip bar that rebounds, sleeve be can move freely and be fixed on the oblique fulcrum bar, reach easy and simple to handle, joint The effect that saves time.

2, support angle regulating structure for body-building device of the present utility model is when operating tip bar with moving sleeve, Be difficult for crushing user's hand, security is higher.
