Multifunctional supination bench
Technical field
The utility model relates to a kind of exercise and fitness equipment, particularly a kind of Multifunctional supination bench that can adopt multiple training method to carry out body building.
Background technology
Along with updating of social development, growth in the living standard and working environment and working condition, blue-collar intensity constantly alleviates; But the time of society's dinner party is more and more, trip mode is also progressively replaced by the modern means of communication, very little free participation body building, fitness but constantly declines, many modern diseases have been brought thereupon, as cervical spondylopathy, lumbar vertebra disease, three high diseases, obesity etc., this not only affects personal image, and can increase the burden of cardio-pulmonary function and derive many angiocardiopathies.In order to adapt to social demand, meet the demand of indoor sports body-building, various body building is flourish, and various exercise and fitness equipments arise at the historic moment.
Board for lying on back is exactly the body-building apparatus that a kind of family and gymnasium are generally used, and by sit-up movement, not only can strengthen belly strength, and can temper cardio-pulmonary function, reaches the effect improving the health.But in use have the following disadvantages: the one, in order to regulate the height of front support seat, generally front support seat is designed to stretching structure, it comprises fixed bar, support bar, fixture block, the first carrying roller, fixed bar is socketed and corresponding multiple fixed bar locating holes that match with screw rod and the support bar locating hole of being provided with mutually with support bar, the front end of screw rod is through the outer surface of fixing and withstand on fixed bar after fixed bar locating hole and support bar locating hole with locking knob, the end of screw rod and fixture block and the first carrying roller are fixed, after locking knob locking, the inner face of fixture block withstands on the outer surface of fixed bar, during due to support bar and fixed bar socket, leave gap, between support bar and fixed bar, in the time taking exercise, can produce and rock, cause the body builder can not easy motion.The 2nd, existing board for lying on back function singleness, can only do sit-ups single action, and body builder easily produces fidgety mood, and body building is difficult to adhere to.The 3rd, existing board for lying on back is mainly to temper the muscle group of belly as main, and other is taken exercise and can not take into account as chest muscle, upper body arm strength and leg power.The 4th, because training time is leaned back, concerning the poor trainer of physique, sit-ups have certain difficulty, can not nimbly and freely, enable, but because of quantity, deficiency of time, also do not have the effect of exercise while doing training action.For this reason, many manufacturers and knowledgeable people develop and develop, but not yet have so far comparatively ideal product to emerge.
Summary of the invention
The above-mentioned defect existing for overcoming existing board for lying on back, the purpose of this utility model be to provide a kind of simple and reasonable, front support seat height is easy to adjust, be connected firmly do not rock, exercise function is many, training effect good, can play to sit-ups the Multifunctional supination bench of power-assisted effect.
The utility model solves the problems of the technologies described above adopted technical scheme, it comprises front support seat, rear support stand, board for lying on back main body, board for lying on back main body is fixed on rear support stand, rear support stand is connected on front support seat, described front support seat comprises fixed bar, support bar, fixture block, the first carrying roller, fixed bar is socketed and corresponding multiple fixed bar locating holes that match and the support bar locating hole of being provided with mutually with support bar, the front end of screw rod is through the outer surface of fixing and withstand on fixed bar after fixed bar locating hole and support bar locating hole with locking knob, the end of screw rod and fixture block and the first carrying roller are fixed, the center of fixture block is provided with circular protrusions, the aperture of the fixed bar locating hole coordinating with screw rod end is greater than the aperture of support bar locating hole and the external diameter of circular protrusions, the aperture of support bar locating hole is less than the external diameter of circular protrusions, after locking knob locking, the end face of circular protrusions withstands on the outer surface of support bar.
The top of described fixed bar is fixed with the second carrying roller.
The front end of described rear support stand is fixed with the 3rd carrying roller.
On described fixed bar, be fixed with Connection Block, the front end of rear support stand is hinged on Connection Block, and Connection Block is provided with the fixed knob of fixing rear support stand.
The top of described fixed bar is provided with elastic pulling force device.
On described rear support stand, be fixed with prostrate strut.
The both sides correspondence of described the first carrying roller, the second carrying roller and the 3rd carrying roller is provided with foam sleeve.
Adopt after said structure, compared with prior art have the following advantages and effect: the one, because its end face after locking knob locking withstands on the outer surface of fixed bar, the end face of circular protrusions withstands on the outer surface of support bar, eliminated the free gap between fixed bar and support bar, make that fixed bar is connected with support bar reliably, firm stable, without rocking.The 2nd, owing to having increased elastic pulling force device on board for lying on back, the poor body builder of physique can utilize elastic pulling force device to carry out power-assisted to alleviate exercise intensity in the time of sit-ups, ensure training action nimbly and freely, can greatly increase the quantity of sit-ups, extend exercise time, can play good training effect.The 3rd, also can lie on the back or be sitting on board for lying on back and utilize elastic pulling force device to carry out left and right SAE, leg training, adapt to different requirements of tempering content, reach different training effects, expand the exercise function of board for lying on back.The 4th, can utilize the motion that presses your body up from the floor with your arms and then lower it slowly of prostrate strut.The 5th, due to simple in structure, cost is low, function is many, ordinary consumer can be accepted, and easily popularizes.
