Description
Technical field
The utility model relates to a kind of body-building board afterbody and adjusts structure.
Background technology
People are when excercising muscle at abdominal part, conventionally use body-building board, as everyone knows, traditional body-building board only has one end lifting structure conventionally, and the other end is often with ground contact, to such an extent as between head and afterbody, there is very large difference in height, therefore in use, because head is downward, so backflow of blood, people, when standing up, because blood concentrates on head, therefore tends to feel rocky sensation, if overexertion, easily blood vessel explosion, therefore, also there are a lot of weak points in the single method of height that regulates of traditional body-building board.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of afterbody at body-building board increases lowering or hoisting gear, make in use, can regulate as required the relative altitude between head Chu Yu foot, safer in use, and the body-building board afterbody with buffering effect is adjusted structure.
The utility model is achieved through the following technical solutions: a kind of body-building board afterbody is adjusted structure and comprised body-building board, described body-building board front end is provided with the first support bar, described body-building board afterbody is provided with the second support bar, described the second support bar is sleeved in a sleeve, sleeve is provided with more than one locating hole outward, on described the second support bar, a side is provided with the connecting hole identical with described locating hole, between described the second support bar and sleeve, by the first tight locking button locking, be connected, described the second support bar is arranged on a positioning block, the bottom of described sleeve is provided with slipmat, the bottom of this slipmat is provided with a buffer unit, described the first support bar runs through and is arranged in body-building board, the positive front end of body-building board is provided with a through hole, the first support bar is provided with the locking hole of working in coordination and being connected with this through hole, between described body-building board front end and the first support bar, by the second tight locking button locking, be connected, in the middle of described the first support bar, being provided with two pin leans on, bottom is provided with slipmat.
As preferred technical scheme, between described locating piece and body-building board, be fixedly connected with this locating piece shape triangular in shape.
As preferred technical scheme, described buffer unit outside is a gauffer cortex, inside only has a spring, and spring bottom contacts with ground.
The beneficial effects of the utility model are: the utility model changes traditional body-building board one end lifting structure, adopt two ends up-down mode, afterbody at body-building board increases lowering or hoisting gear, make in use, can regulate as required the relative altitude between head Chu Yu foot, safer in use, and there is buffering effect.
