Abstract
The invention provides a supporting leg for a sit-up board. The supporting leg aims to solve the problem that the stability of the sit-up board capable of exercising the obliquus internus abdominis and the obliquus externus abdominis is poor in the prior art. The supporting leg for the sit-up board comprises two cylinders fixedly connected to the front end and the rear end of a horizontal rod respectively and arranged in the axial left-right direction in parallel, and a supporting rod with one end provided with threads. The side wall of each cylinder is provided with two or more threaded holes matched with the threaded portion of the supporting rod. According to the supporting leg for the sit-up board, the cylinders are arranged and provided with the threaded holes, the supporting rods can be inserted into the corresponding threaded holes in the cylinders according to the rotation angle of an inclining board, and therefore the sit-up board can be more stable.
Description
Technical field
The present invention relates to a kind of abdominal boards supporting leg.
Background technology
Abdominal boards for tempering oblique musculus ventralis interni and oblique musculus ventralis externi, need to be rotated swash plate, for postrotational swash plate, needs supporting leg to be fixed, and when swash plate rotates to operating angle, supporting leg need to carry out supporting & stablizing to abdominal boards.
Summary of the invention
The invention provides a kind of abdominal boards supporting leg, be intended to solve in prior art for the problem that can temper oblique musculus ventralis interni and oblique musculus ventralis externi abdominal boards poor stability.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of abdominal boards supporting leg, comprise two be connected in respectively horizon bar rear and front end and the horizontally disposed cylinder of axis left and right directions, threaded pole is established in one end, is equipped with the screwed hole that at least two threaded portions with pole match on the sidewall of each cylinder.
Further, screwed hole has four, is conducive to realize the adjusting to pole angle according to the anglec of rotation of swash plate.
Further, described pole is expansion link; The versatility that is conducive to pole.
Further, described pole comprises the upper boom being connected with cylinder, the lower beam being connected with upper boom by screw thread; Be convenient to the flexible and fixing of pole.
Further, described pole comprises the upper boom that is connected with cylinder, is socketed in the connected lower beam of upper boom, is connected with bundle young between described upper boom and lower beam; Be convenient to the flexible and fixing of pole.
Compared with prior art advantage of the present invention is: the present invention is provided with cylinder, and cylinder is provided with a plurality of screwed holes, and pole can be inserted cylinder in corresponding screwed hole according to the anglec of rotation of swash plate, is conducive to abdominal boards more stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention in embodiment mono-;
Fig. 2 is structural representation of the present invention in embodiment bis-.
The specific embodiment
Embodiment mono-:
Consult Fig. 1, a kind of abdominal boards supporting leg, comprise two be connected in respectively horizon bar 3 rear and front ends and the horizontally disposed cylinder 1 of axis left and right directions, threaded pole 2 is established in one end, is equipped with the screwed hole 11 that four threaded portions with pole 2 match on the sidewall of each cylinder 1; Described pole 2 is expansion link; Described pole 2 comprises the upper boom 21 being connected with cylinder 1, the lower beam 22 being connected with upper boom 21 by screw thread.
During use, swash plate 4, according to the angle of swash plate 4, can make swash plate 4 stably in screwed hole 11 pole 2 insertion, adjusts the length of pole 2, makes pole 2 kiss the earths; The effect of screwed hole 11 is to adjust the angle of pole 2; The effect that pole 2 can be stretched is can not need to be equipped with the many poles 2 that length is different, one of a need.
When low after the front height of swash plate 4, on the cylinder 1 of rear side, do not need to insert pole 2, take cylinder 1 as the strong point, only need on the cylinder 1 of front side, insert pole 2; When swash plate 4 is low early and high after, on the cylinder 1 of front side, do not need to insert pole 2, only need on the cylinder 1 of rear side, insert pole 2; When swash plate 4 anterior and posterior heights are when identical, on two cylinders 1, not inserting pole 2, one or two cylinders 1 is the strong point.
Embodiment bis-:
Consult Fig. 2, be with the difference of embodiment mono-: described pole 2 comprises the upper boom 21 that is connected with cylinder 1, is socketed in the connected lower beam of upper boom 21 22, between described upper boom 21 and lower beam 22, be connected with bundle young 23; Stretching of described pole 2, and the relative fixing of upper boom 21 and lower beam 22 realized by restrainting young 23.
The present invention is provided with cylinder, and cylinder is provided with a plurality of screwed holes, and pole can be inserted cylinder in corresponding screwed hole according to the anglec of rotation of swash plate, is conducive to abdominal boards more stable; Pole can be stretched, and only needs a pole just can meet the demands.
The foregoing is only specific embodiments of the invention, but technical characterictic of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed among the scope of the claims of the present invention.
