Detailed Description

The invention is explained in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1-4, a be used for muscle tensile training apparatus, including bottom plate 1, elevating gear 2, back 3, headrest 4, rubber pad 5, adjustable swinging arms 6, elevating gear 2 is installed to bottom plate 1 upper end rear side, and 2 upper ends of elevating gear install back 3, headrest 4 is installed to 3 upper ends of back, and both ends respectively are fixed with rubber pad 5 about back 3, two rubber pad 5 can reduce the striking dynamics of two adjustable swinging arms 6 to back 3, the back 3 left and right sides respectively articulates there is adjustable swinging arms 6.

Elevating gear 2 includes U type frame 7, traveller 8, screw rod 9, hand wheel 10, each vertical traveller 8 that is fixed with of U type frame 7 upper end left and right sides, two

traveller

8 and 3 sliding connection of back, 7 mid-portions of U type frame rotate and install screw rod 9, and the screw rod 9 lower extreme is fixed with hand wheel 10,

screw rod

9 and 3 middle part threaded connection of back, screw rod 9 rotates and to make back 3 upwards or the lapse along two travellers 8.

Adjustable swinging arms 6 includes slide rail 11, rack 12, slider 13, slide cartridge 14, adjusts spout 15, adjusts traveller 16, triangle inserted block 17, spring 18, control lever 19, the vertical rack 12 that is fixed with of slide rail 11 rear portion front end, and slider 13 and slide rail 11 sliding connection, slide cartridge 14 runs through slider 13 middle part, and has opened and adjust spout 15 in slide cartridge 14 upper end front side, it is inner at slide cartridge 14 to adjust traveller 16 slidable mounting, and adjusts the 16 rear end of traveller and be fixed with triangle inserted block 17, triangle inserted block 17 and the meshing of rack 12, the level is fixed with spring 18 between slide cartridge 14 front side rear end and the 16 front ends of regulation traveller, the vertical control lever 19 that is fixed with of adjusting the 16 upper end front sides of traveller, and control lever 19 vertically passes and adjusts chute 15.
