[0022] Embodiment 1

[0023] See also Figures 1 to 4 As shown, a multifunctional abdominal arm trainer comprises an arm trainer body 1, a pressure spring 2 is installed at the end of the arm trainer body 1, and a first threaded protrusion 3 is arranged on the right side of the outer wall of the arm trainer body 1, an abdominal structure 4 is installed on the outer wall of the first threaded protrusion 3, and a bearing 5 is arranged inside the abdominal structure 4, a roller 6 is installed on the outer wall of the bearing 5, a gasket 7 is arranged on the outer wall of the roller 6, and a slide groove 8 is reserved on the inner wall of the roller 6, a second threaded protrusion 9 is installed on the outer wall of the abdominal structure 4, and an adjusting knob 10 is arranged on the outer wall of the second threaded protrusion 9, a threaded groove 11 is reserved on the inner wall of the adjusting knob 10, an adjusting block 12 is installed on the right side of the adjusting knob 10, and a slope protrusion 13 is arranged on the outer wall of the adjusting block 12.

[0024] The arm trainer body 1 is symmetrically arranged about the central axis of the pressure spring 2, and the pressure spring 2 and the arm trainer body 1 are integrated. The user holds the arm trainer body 1 with both hands to bend the middle pressure spring 2, thereby achieving the effect of exercising arm strength. The outer wall of the pressure spring 2 is covered with a plastic film, which can protect the pressure spring 2 and prevent the pressure spring 2 from being corroded by water vapor in the air and causing the pressure spring 2 to rust and be damaged.

[0025] The abdominal fitness structure 4 is threadedly connected to the arm strength trainer body 1, and the abdominal fitness structure 4 forms a rotating structure through the bearing 5 and the roller 6. When abdominal fitness exercises are needed, the first threaded protrusion 3 is connected to the abdominal fitness structure 4, and then the entire device is placed on the ground. By holding the arm strength trainer body 1 with both hands, the device is rolled forward through the roller 6, thereby having the abdominal fitness function. When performing abdominal fitness exercises, the abdominal fitness structure 4 is directly connected to the arm strength trainer body 1, and the pressure spring 2 is inside the abdominal fitness structure 4, which can make the abdominal fitness structure 4 run more stably and will not be affected by the elasticity of the pressure spring 2. At the same time, two rollers 6 are symmetrically arranged, so that the abdominal fitness structure 4 is subjected to more uniform force, thereby further improving stability.

[0026] The adjusting knob 10 forms a detachable structure with the abdominal fitness structure 4 through the second threaded protrusion 9, and the adjusting knob 10 forms a sliding structure with the slide groove 8 through the adjusting block 12. By rotating the adjusting knob 10, the adjusting block 12 is gradually fitted into the slide groove 8 inside the roller 6. The slope protrusion 13 on the outer wall of the adjusting block 12 is inclined. The more the adjusting knob 10 is rotated, the more the slope protrusions 13 fit into the roller 6. The adjusting block 12 is made of rubber material, which can increase the friction between the roller 6 and the adjusting knob 10 and increase the force required for rotation, so as to facilitate adjustment according to the intensity of exercise and adapt to users with different physical fitness, thereby having an adjustment function and being more practical.

[0027] Embodiment 2

[0028] See also Figure 1 to Figure 2 as well as Figure 4 As shown, a multifunctional abdominal arm trainer is provided, wherein an anti-skid protrusion 14 is installed on the side of the first threaded protrusion 3, and a limiting ring 15 is provided on the right side of the anti-skid protrusion 14, a pressure sensing sheet 16 is installed below the anti-skid protrusion 14, and an alarm 17 is provided on the left side of the pressure sensing sheet 16.

[0029] The anti-slip bumps 14 and the pressure sensing sheet 16 are bonded with glue, and the pressure sensing sheet 16 and the alarm 17 are electrically connected. There are multiple pressure sensing sheets 16, which can sense the gripping force of the user's hand on the arm trainer body 1. When it is detected that the gripping force is rapidly reduced, the alarm 17 will remind the user to prevent exhaustion during exercise and cause injury. The anti-slip bumps 14 can increase friction to prevent the device from slipping out of the hand during exercise. The limit ring 15 can limit the abdominal structure 4, so that the installation position of the abdominal structure 4 is more accurate.

[0030] Working principle: First, the user holds the arm trainer body 1 with both hands to bend the middle pressure spring 2, so as to achieve the effect of exercising arm strength. The outer wall of the pressure spring 2 is covered with a plastic film, which can protect the pressure spring 2. When it is necessary to do abdominal exercises, the first threaded protrusion 3 is connected with the abdominal structure 4, and then the device is placed on the ground as a whole. By holding the arm trainer body 1 with both hands, the device is rolled forward through the roller 6, so that it has the abdominal function. When doing abdominal exercises, the abdominal structure 4 is directly connected to the arm trainer body 1, and the pressure spring 2 is inside the abdominal structure 4. At the same time, two rollers 6 are symmetrically arranged, so that the abdominal structure 4 is more evenly stressed;

[0031] Finally, by turning the adjustment knob 10, the adjustment block 12 is gradually fitted into the slide groove 8 inside the roller 6. The slope protrusion 13 on the outer wall of the adjustment block 12 is inclined. The more the adjustment knob 10 is turned, the more slope protrusions 13 fit into the roller 6. The adjustment block 12 is made of rubber material, which can increase the friction between the roller 6 and the adjustment knob 10 and increase the force required for rotation. There are multiple pressure sensing sheets 16, which can sense the gripping force of the user's hand on the arm trainer body 1. When it is detected that the gripping force is rapidly reduced, the alarm 17 will remind the user to prevent exhaustion during exercise and cause injury.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
