Problems solved by technology

This kind of influence is accumulated over time and becomes more and more serious. Inadvertent and laissez-faire attitudes will lead to malignant changes in body functions in the future. Therefore, with the continuous improvement of people's living standards, people pay more and more attention to physical exercise. Many families buy fitness equipment. Fitness equipment can help us exercise. It is essential for people who work with computers for a long time to have a sit-up board for spine and abdomen exercise, but the structure of the home-use sit-up boards on the market is relatively complicated , the foot hook bars of these supine boards cannot be adjusted in height, so these supine boards are only suitable for a certain range of people during use. Therefore, a supine board that can adjust the height of the foot hook rods and has a simple structure is proposed, especially is an adjustable supine board

Embodiment 1

[0025] refer to figure 1 , is a structural schematic diagram of Embodiment 1 of the present invention, an adjustable sit-up board, at least including a sit-up board 1, a foot support rod 2 and a head support device 3, one end of the sit-up board 1 and a foot support rod 2 Fixedly connected, the lower surface of the other end of the sit-up board 1 is fixedly connected with a head support device 3, which is characterized in that: the middle part of the foot support rod 2 is fixedly connected with a bracket 9 perpendicular to it, and the bracket 9 is located on the sit-up board 1, and forms an angle of 20° to 40° with the sit-up board 1, a chute is provided in the vertical direction on the support 9, and a slide bar 14 is slidably connected in the chute, and the outer wall of the slide bar 14 is also connected to the The foot hook bar 12 outside the chute is fixedly connected with the foot pad bar 13, and the head support device 3 is provided with a lifting device; the sit-up boa...

Embodiment 2

[0028] refer to figure 1 and 3 , is a schematic structural view of Embodiment 2 of the present invention. Compared with Embodiment 1, the difference of this embodiment is that a bracket positioning hole 10 is opened on one side of the chute in the middle section of the rod wall of the bracket 9, and the sliding The bar 14 has a plurality of slide bar positioning holes distributed at intervals along its lengthwise side wall, and the bracket positioning holes 10 are pinned with the slide bar positioning holes by the positioning pin 11 so as to limit the position of the slide bar 14 in the chute of the bracket 9 .

[0029] During actual use: when the foot hook bar 12 and the foot pad bar 13 slide on the bracket 9 through the slide bar 14, when adjusted to a suitable comfort height, pass the positioning pin 11 through the positioning hole 10 and the slide bar on the slide bar 14. Rod positioning holes are used for positioning. Using this positioning method, the positioning is sta...

Embodiment 3

[0031] Compared with Embodiment 2, the difference of this embodiment is that the head support device 3 includes a head support rod 17 supported on the ground, an outer sleeve vertically fixed to the head support rod 17, and an end Socketed in the connecting rod 4 that the other end is fixedly connected with the lower surface of the sit-up board 1 in the outer sleeve, there is a lifting device between the connecting rod 4 and the outer sleeve.

[0032] In actual use: when doing sit-ups, adjust the lifting device of the head according to the height of the center of gravity to adjust the center of gravity of the human body. Adjust the lifting device to lower the head position when the stretching strength is large, that is, the connecting rod 4 is lowered to the lowest in the outer sleeve, and the center of gravity of the human body is also lowered accordingly. The difficulty of doing sit-ups increases, and the stretching strength also increases. Increase, within the lifting range...

Abstract

The invention relates to the field of fitness equipment, in particular to an adjustable supine board. The adjustable supine board comprises a sit-up board 1, a foot support rod 2 and a head support device 3 at least; one end of the sit-up board 1 is fixedly connected with the foot support rod 2, and the lower surface of the other end of the sit-up board 1 is fixedly connected with the head supportdevice 3. The adjustable supine board is characterized in that the middle of the foot support rod 2 is fixedly connected with a support frame 9 perpendicular to the foot support rod 2, the support frame 9 is located on one side of the upper surface of the sit-up board 1, an included angle of 20-40 degrees is formed between the support frame 9 and the sit-up board 1, a slide groove is formed in the support frame 9 in the vertical direction, the slide groove is internally and slidably connected with a slide rod 14, the outer wall of the slide rod 14 is fixedly connected with a foot hooking rod12 and a foot pad rod 13 which are located outside the slide groove, and a lifting device is arranged on the heat support device 3.

Description

Technical field [0001] The invention relates to the field of fitness equipment, in particular to an adjustable supine board. Background technique [0002] Long hours of computer work will inevitably affect people's health. This kind of influence is accumulated over time and becomes more and more serious.
