specific Embodiment 1

[0031] Refer to the attached Figure 1 to Figure 3 As shown, a leg exercise assisting device includes a chassis 1 and a seat 2 . The seat 2 is located above the chassis 1, and the seat 2 is connected to the chassis 1 through a guide rod 3. One end of the guide rod 3 is fixed on the bottom of the seat 2 , the underframe 1 includes an upper fixed plate 11 and a middle fixed plate 12 , and the guide rod 3 runs through the upper fixed plate 11 and the middle fixed plate 12 . The guide rod 3 below the upper fixed plate 11 and the middle fixed plate 12 is respectively provided with a first stop ring, and the guide rod 3 between the upper fixed plate 11 and the middle fixed plate 12 is covered with a first return spring 4 . The seat 2 includes a seat back 21 , and two sets of correction components are arranged at the rear of the seat back 21 , and the correction components include a pressing column 51 , a lever 52 , a sleeve 53 , a push-pull rod 54 , and a baffle 55 . The upper par...

specific Embodiment 2

[0035] This specific embodiment further improves the structure on the basis of the specific embodiment 1, and its added function is to monitor whether the back is straight.

[0036] The back of the chair in this specific embodiment is designed according to the curvature curve of the human spine, and the back of the chair fits the back of the human body.

[0037] Refer to the attached Figure 5 As shown, the back of the chair is also provided with a third group of correction components 5, the pressing column corresponds to the position of the back, and push-pull rods are respectively provided on both sides of the bottom of the sleeve, and each push-pull rod is connected to a baffle plate respectively.

[0038] For the third group of correction components in this specific embodiment, when the back presses the pressing column, the two corresponding baffles can be controlled simultaneously. For specific working principle, please refer to the attached Image 6 with Figure 7 sho...

specific Embodiment 3

[0040] In order to facilitate the adjustment of the height of the seat and make it suitable for exercisers of different heights, an improvement is made on the basis of the first embodiment. Refer to the attached Figure 8 As shown, the first stop ring under the upper fixing plate 11 is the first positioning nut 31 , and the first stop ring under the middle fixing plate 12 is the second positioning nut 32 . The first positioning nut 31 and the second positioning nut 32 are respectively connected with the guide column 3 through threads. The fixed shaft 57 is threadedly connected with the upper fixed plate 11 .

[0041] In this specific embodiment, by adjusting the position of the first positioning nut 31, the height of the base can be adjusted, making it suitable for exercisers of different heights. By adjusting the distance between the first positioning nut 31 and the second positioning nut 32, the degree of compression of the first return spring 4 can be adjusted to adjust t...

Abstract

The invention relates to a leg exercise assisting device, which comprises a bottom frame and a seat, wherein the seat is connected with the bottom frame through a guide rod, the guide rod between an upper fixing plate and a middle fixing plate is sleeved with a first reset spring, two sets of correction assemblies are arranged on the rear portion of a seat back, each correction assembly comprises a pressing column, a lever, a bushing, a push-pull rod and a baffle, the pressing column corresponds to the shoulder part in position, the lever is arranged on the rear portion of the pressing column, the lower portion of the lever is inserted into the bushing, and the push-pull rod is arranged at the bottom of the bushing and connected with the baffle. According to the invention, when a second reset spring is in a natural state, one part of the baffle is located at the bottom of the seat, and when the pressing column is extruded, the baffle rotates out of the bottom of the seat; and the device can be used for monitoring whether the shoulders of the exerciser are opened in place or not.

Description

technical field [0001] The invention relates to the technical field of fitness devices, in particular to an auxiliary device for exercising legs. Background technique [0002] The main points of leg exercise include: open your feet, put your hands on top of each other, keep your back straight, open your shoulders, squat down until your thighs are parallel to the ground, then move your body up and back and forth. During exercise, it is difficult for exercisers to straighten their backs and open their shoulders. Existing squatting equipment seldom has the function of monitoring whether the action is standard. If monitoring is carried out by sensors, the monitoring is not intuitive and does not provide a good monitoring and guiding effect for exercisers. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide an auxiliary device for leg exercise, which is convenient for monitoring the movement of the exerciser, and ...
