Description
Technical field
The present invention relates to the body-building apparatus technical field, relate in particular to a kind of apparatus for body building with sit-ups.
Background technology
Along with the development and progress of society, the raising of people's living standard has also brought many modern diseases, such as hypertension, high fat of blood and abdominal fatness etc.In order to eliminate the abdominal obesity phenomenon, the most direct effective way is to perform physical exercise for belly, and the simplest method is carried out sit-up movement exactly.
Existing supine exercise machine mainly contains straight fixed, the public place of park, residential quarter has, although can realize the purpose of taking exercises, limited by the place, must arrive the outdoor place that fitness equipment is arranged, the angle of lying on the back can not be adjusted, be not suitable with different abdominal obesity body builders' needs, stressed excessive to lumbar vertebrae when simultaneously straight fixed apparatus for body building with sit-ups is taken exercise, the body builder is very tired, also without benefit, even can cause the injured lumbar vertebrae of lumbar vertebrae to lumbar vertebrae.
Summary of the invention
The deficiency that exists for overcoming existing apparatus for body building with sit-ups the invention provides a kind of apparatus for body building with sit-ups, and simple and reasonable, body-building effect is good, not limited by the place, can carry out at home.
To achieve these goals, the present invention adopts following technical scheme: apparatus for body building with sit-ups comprises front support stand, rear support stand, lie on the back and pull bracing frame and lie on the back and pull, lie on the back and pull supporting framing front end and be connected with front support stand, the rear end is connected with rear support stand, above be connected with lying on the back to pull.Sponge knee carrying roller, sponge pin carrying roller and front support pin are arranged on the described front support stand, and the sponge knee carrying roller of front support stand below is pulled supporting framing front end and is connected with lying on the back, for firm added with triangle iron plate is welded and fixed.Describedly lie on the back that to pull bracing frame be by being welded after the two joint rectangle iron pipe cuttings, angle is 165 degree between two joints, two holes that are communicated with are up and down arranged on the iron pipe, be welded with respectively two bands, three hole band irons, the hole on the iron pipe is aimed in hole in the middle of the three hole band irons, is welded with a band 15 degree inclined-plane iron tenon band irons on the rear end face, and two holes are arranged on the band iron, what the rear end linked to each other with rear support stand is fixed rotating shaft, and the side, rear end is welded with the switch plate of three locating holes.Described rear support stand has rear support pin, locating hole, fastening screw, and one of three locating holes of the corresponding switch plate in running fix hole are plugged fastening screw, can regulate the height of rear support stand.Described lie on the back to pull comprise elastic plate, sponge layer and overcoat, there are 8 holes to pull hole corresponding on the bracing frame with lying on the back respectively on the elastic plate, connect with screw, nut, pad, pull angle on the bracing frame owing to lie on the back, force elastic plate to become arc shape after the connection, stick the sponge layer, wrapping overcoat becomes apparatus for body building with sit-ups.
The beneficial effect of a kind of apparatus for body building with sit-ups of the present invention is: pull angle on the bracing frame owing to lie on the back, make abdominal boards become arc shape, lumbar vertebrae is had protective effect, because the effect of sponge layer, the body builder is lain in lie on the back and pull motion comfort sense is arranged.Different locating holes on the corresponding switch plate of mobile rear support stand locating hole can be regulated the height of rear support stand, adapt to respectively different exercise intensity body builders' demand, the high exercise intensity of rear support stand is little, good for the underbelly fat-reducing effect, the low exercise intensity of rear support stand is large, and is good for the upper abdomen fat-reducing effect.
