When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

In addition, it should be noted that the orientation terms such as left, right, up, and down in the embodiment of the utility model are only relative concepts or refer to the normal use state of the parts to be punched, and should not be regarded as is restrictive. The realization of the utility model is described in detail below in conjunction with specific embodiments.

The utility model provides an abdominal exercise machine containing a guide rail 13. The abdominal exercise machine includes a horizontal support 1, a rolling device 14 that can roll on the horizontal support 1, and is arranged on the support to guide the movement of the rolling device 14. The guide rail 13, and the damper 3 connected with the rolling device 14 through the transmission mechanism 2. Because the guide rail 13 is provided, the movement trajectory of the wheels is limited, so that the body maintains a straight posture all the time, ensuring safety while allowing the exercise position to be more accurate and effective. It overcomes the disadvantages of the traditional abdominal wheel that is easy to go off. At the same time, when the body moves forward, the built-in damper 3 will work to increase the resistance of the movement, so that the user is not easy to lose control of the movement, which can ensure the safety of the exercise, and overcomes the traditional abdominal exercise. The disadvantage that the wheel is difficult to control the strength.

Further, the abdominal exercise machine also includes a pedal 11 obliquely arranged on the horizontal support 1, the pedal 11 is arranged at one end of the horizontal support 1, the pedal 11 is provided with an anti-slip structure, the pedal 11 The inclination angle is between 20-60°.

The pedal 11 provides a resting point and thrust for the user's feet. , the user's upper body and lower body are on the same horizontal line, which regulates the standardization of exercise. The angle design of 20-60° is a more suitable angle for the user's feet, which is in line with human mechanics. At the same time, anti-slip structures are added to the pedal 11, and the anti-slip structures include but not limited to horizontal stripes or concave-convex points, so as to enhance the safety of sports. In other embodiments, the pedal 11 can also be replaced with a horizontal step column or other structures that can place the user's feet.

Further, a limiting member 15 for limiting the movement of the rolling device 14 is provided at the end of the guide rail 13 . In this embodiment, the limiting member 15 is a beam arranged at the end of the guide rail 13 . When the rolling device 14 moved to the crossbeam, it was limited by the crossbeam and could not be pushed forward. In other embodiments, the limiting member 15 can also be of other structures, even a structure whose position on the horizontal support 1 can be adjusted. This makes the utility model adaptable to the exercise of different groups of people, prevents the body from hitting the face close to the ground when the body leans too far forward, and avoids the damage caused by the excessive displacement of the rolling device 14 caused by the user losing control.

Further, two installation plates 12 are arranged on the guide rail 13 , and the installation boards 12 are respectively arranged on two sides of the guide rail 13 .

Therefore, it is suitable for different groups of people or different stages of exercise.

Further, the abdominal exercise machine is provided with a metering structure. In this embodiment, the metering structure is a meter arranged on the guide rail 13, and the metering surface faces the user. When the rolling device 14 is pushed, the rolling device 14 will move back and forth in the meter along the direction of the user's movement. In the production stage, the relationship between the difficulty of exercising the rolling device 14 and the displacement point is calculated through experiments, and the exercise intensity represented by different positions can be marked on the surface of the meter. This method can intuitively allow users to observe the difficulty factor of their current exercise, so as to adjust their own exercise intensity.

Further, the bottom of the horizontal support 1 is provided with an anti-slip structure. The anti-slip structure includes but is not limited to horizontal stripes or raised rubber pads 101, which are used to prevent the entire abdominal exercise machine from shifting during exercise.

The guide cavity is a cavity composed of an upper guide rod 131 and an inverted "U" shaped lower guide rod 132 . The design is compact and easy to produce.

Further, the transmission mechanism 2 includes a pillar 22 fixed inside the horizontal support 1, and a transmission wheel 21 rotating around the pillar 22, the rolling device 14 is connected with the transmission wheel 21 through a connecting rope 23, the The transmission wheel 21 is connected with the damper 3 . In a specific embodiment, the diameter of the rolling wheel 142 is larger than that of the transmission wheel 21, preferably 1.8:1-6:1. The pillar 22 is fixed inside the horizontal support 1, and the transmission wheel 21 rotates on the pillar 22. When the user pushes the scroll wheel 142 to roll, because the diameter of the scroll wheel 142 is relatively large, when the scroll wheel 142 moves with a relatively large stroke, the transmission wheel 21 The stroke of rotation is relatively short, thereby reducing the required motion length of the damper 3, and the short-stroke damper 3 can also be applied in the utility model, so that the utility model has a compact structure, and the required horizontal support 1 is greatly reduced , saving steel and practice space.

Further, the damper 3 is arranged inside the horizontal guide rail 13, the damper 3 includes a hollow cylinder 301 with an end cover 302 and a connecting rod passing through the cylinder 301, the middle part of the connecting rod is provided with a positioning 307, the positioning rod divides the connecting rod into a first connecting rod 303 and a second connecting rod 304, a metal compression spring 305 is set on the first connecting rod 303, and one end of the metal compression spring 305 is connected to one end of the cylinder body 301 The other end of the end cap 302 is connected to one side of the positioning member 307, and the metal compression spring 305 is a cylindrical helical compression spring. The hollow cylinder 301 has a cavity 306, the positioning member 307 and the metal compression spring 305 are placed in the cavity 306 of the cylinder 301, and the ends of the first connecting rod 303 and the second connecting rod 304 protrude from different sides of the cylinder 301 respectively. , the first connecting rod 303 is fixedly connected in the horizontal support 1 , and the second connecting rod 304 is connected to the transmission wheel 21 . When the user pushes the scroll wheel 142, the scroll wheel 142 drives the transmission wheel 21 to rotate through the connecting rope 23, thereby pulling the second connecting rod 304 to displace, and the metal compression spring 305 is compressed to generate resistance. The damper 3 of this embodiment has a simple structure and no liquid leakage, so that the vertical tensioner can be applied in the field of public fitness facilities to prolong the service life and reduce damage and maintenance rates. Of course, in other embodiments, the viscous medium can also be poured into the cavity 306306 of the cylinder body 301 and then sealed to increase the resistance of the damper 3 .
