Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fitness equipment, and in particular relates to an auxiliary fitness equipment for abdominal exercise. Background Art
[0002] Sit-ups are an important part of physical training, and their main function is to strengthen the abdominal muscles. If done correctly, sit-ups can not only increase the elasticity of the abdominal muscles, but also protect the back and improve the body shape. Sit-ups are an effective way to train the abdominal muscles and are a simple exercise method that is quite suitable for the general public.
[0003] In the process of sit-up training, the abdominal muscles are usually used to drive the upper body to exercise. However, many people are not technicians in the field of fitness, so many ordinary people often use waist strength to train when doing sit-ups. If you use too much force or exercise for too long when doing sit-ups, it may cause damage to the lumbar spine and waist muscles, resulting in waist sprains, muscle strains, etc. If the trainee's own strength is insufficient and the movements cannot be performed correctly, it will cause continuous force on the cervical spine, which is easy to cause neck pain symptoms.
[0004] Therefore, we propose an abdominal exercise auxiliary fitness equipment to solve the above technical problems. Utility Model Content
[0005] In order to solve the technical problem in the prior art that novice trainees often suffer from neck pain and waist discomfort due to being unable to perform the movements correctly when doing sit-ups, the utility model provides an abdominal exercise auxiliary fitness equipment.
[0006] The technical solution adopted by the utility model is as follows:
[0007] An abdominal exercise auxiliary fitness equipment comprises a training chair body, wherein the training chair body comprises a chair body, a chair back, a foot assist rod and a drive connection assembly, wherein the chair back and the foot assist rod are rotatably connected to both sides of the chair body, respectively, and the two ends of the drive connection assembly are respectively connected to the chair back and the foot assist rod, and the chair back is driven to rotate inward when the foot assist rod rotates upward.
[0008] By adopting the above technical scheme, when the utility model is used, the trainee sits on the chair body, leans against the chair back, and then clamps the foot assist rod with both feet, and lifts and rotates the foot assist rod upward, so that the chair back is synchronously rotated inward under the drive of the driving connection component, that is, assists the trainee to stand up. This design not only allows the trainee to perform abdominal training in a sitting state, but also can assist the movement of the upper body by exerting force with both feet when the trainee's own strength is insufficient, thereby achieving an auxiliary training effect, thereby reducing the dependence on waist strength, reducing the burden on the lumbar spine and waist muscles, and reducing the neck pain and back discomfort caused by excessive force or incorrect posture of the trainee. Compared with the traditional sit-up method, the use of this equipment can be safer and more effective for abdominal training, improve the health of abdominal muscles, and is a simple exercise method that is quite suitable for the general public.
[0009] In a further technical solution, a rotating rod is connected to the lower part of the chair back, sleeves are sleeved on both sides of the rotating rod, the two sleeves are fixedly connected to the chair body, and the rotating rod is connected to the driving connection assembly.

[0014] By adopting the above technical solution, the driving connection assembly cooperates with the support, the support rod, the first connecting block, the second connecting block and the driving rod. When the trainee lifts the foot-assisting rod with both feet, the support rod rotates upward with the foot-assisting rod, thereby pushing the first connecting block, the driving rod and the second connecting block in turn, so that the driving force can be effectively transmitted to the chair back, realizing the function of driving the chair back to rotate inward, thereby pushing the trainee's upper body to curl up, effectively training the abdominal muscles, and due to the smoothness of the transmission during the movement process, the training experience is also better.
[0015] In a further technical solution, a support rod is provided on the foot assist rod, the support rod is located above the support rod and the directions of the support rod and the support rod are perpendicular to each other.

The first mounting seat is connected to the chair back, and the second mounting seat is connected to the chair body. The two ends of the reset spring are respectively installed on the first mounting seat and the second mounting seat, so that the chair back can rotate inward.
[0018] By adopting the above technical solution, the reset component is installed on the first mounting seat and the second mounting seat on the chair back and the chair body, and the reset spring connecting the two, so that the chair back can rotate inward and automatically return to the initial position after releasing the elastic potential energy. When lying down slowly during training, the chair back can have a certain damping effect in the process of rotating outward, ensuring that it is safe enough when lying down, and when getting up, the reset spring can also release the elastic potential energy, which serves as another force to assist training, which is convenient for use.
[0019] In a further technical solution, the chair body includes a seat plate and chair leg brackets connected to both sides of the seat plate, the foot assist rod is hinged under the seat plate, and anti-slip pads are provided under the two chair leg brackets.
[0020] By adopting the above technical solution, an anti-skid pad is provided under the chair leg bracket, which effectively avoids slipping and ensures safety during training.
[0021] In a further technical solution, an armrest is provided above the chair leg bracket.
[0022] With the above technical solution, the design of the armrests enables trainees to maintain balance and control posture more easily, especially for those with weaker strength or novice trainees, the setting of the armrests can help them better master movement skills and reduce the risk of injury.
[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
