Embodiment 1

[0019] refer to figure 1 , figure 2 with image 3 , a sit-up board, comprising a right strut 1 inclined downward to the right, a left strut 2 whose right end is connected to the right strut 1 and inclined downward to the left, and a slant plate 3 fixedly connected to the left strut 2, The right pole 1 is provided with a circular tube 11 matching the upper end of the left pole 2, and the outer wall of the upper end of the left pole 2 is provided with at least three positioning holes 21 on the circumference, and the circular pipe 11 is provided with There is a positioning pin 4 that matches each positioning hole 21; the number of the positioning holes 21 is an odd number; when the positioning pin 4 is inserted into the positioning hole 21 in the middle, the front and rear direction of the swash plate 3 does not tilt; when the positioning pin 4 When inserted into the positioning hole 21 on the front side of the middle positioning hole 21, the front side of the swash plate 3 is...

Embodiment 2

[0024] refer to Figure 4 , the difference from Embodiment 1 is that the cross-section of the upper end of the left strut 2 is a regular dodecagon.

[0025] in will figure 1 becomes figure 2 , it is necessary to pull out the left pole 2, adjust the angle of the left pole 2, and then insert it into the round tube 11. The polygonal contour is used to increase the stability of the left pole, and the positioning holes 21 are respectively located on different but adjacent sides. On, all the other are identical with embodiment one.

[0026] The inclined board in the present invention can not only exercise the rectus abdominis by tilting left and right, but also can exercise the internal and external oblique muscles by tilting forward and backward, so that the exercise is more comprehensive and the exercise effect is better; the intensity of the exercise can be adjusted as required.

Abstract

The invention relates to an abdominal muscle exerciser, in particular to a sit-up board. The sit-up board aims to solve the problem that the obliquus internus abdominis or the obliquus externus abdominis can not be effectively exercised through an existing sit-up board. The sit-up board comprises a right supporting rod, a left supporting rod and an inclining board. A round tube is arranged on the right supporting rod. An odd number of locating holes are formed in the outer side wall of the upper end of the left supporting rod in the circumferential direction. A locating pin is arranged on the round tube. When the locating pin is inserted into the middle locating hole, the front-back side of the inclining board does not incline; when the locating pin is inserted into the locating hole in front of the middle locating hole, the front side of the inclining board inclines upwards; when the locating pin is inserted into the locating hole in back of the middle locating hole, the back side of the inclining board inclines upwards. A horizontal rod is fixedly connected to the left end of the left supporting rod, and the front end and the back end of the horizontal rod are respectively provided with a telescopic supporting leg. According to the sit-up board, the inclining board can incline left and right to exercise the rectus abdominis and also can incline front and back to exercise the obliquus internus abdominis and the obliquus externus abdominis, and therefore more comprehensive exercise and a better exercise effect can be achieved.

Description

technical field [0001] The invention relates to an exercise equipment for abdominal muscles, in particular to a sit-up board. Background technique [0002] At present, many fitness enthusiasts use sit-up boards to exercise abdominal muscles, making their body more perfect, but the existing sit-up boards, such as the sit-up board described in the application number 201120328964.0, can only exercise people. the rectus abdominus, but can not exercise people's internal oblique and external oblique; And the exercise of the external oblique muscles, this kind of exercise is less effective. Contents of the invention [0003] The invention provides a sit-up board, which aims to solve the problem that the existing sit-up board cannot effectively exercise the internal oblique muscles and the external oblique muscles. [0004] In order to solve the above technical problems, the present invention is realized through the following technical proposals: a sit-up board, comprising a rig...
