[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] See also Figure 1The present utility model discloses a fitness device with adjustable force lines, comprising a support frame 1, an adjustment device 2, a swing arm 3, a connecting rod 4, a movable arm 5, and a support rod 6. The adjustment device 2 includes a positioning plate 21 and an adjustment member 22. The support frame 1 is the main body of the fitness device, used to support the entire device. One end of the support rod 6 is fixedly connected to the upper portion of the support frame 1 and is used to connect to the swing arm 3. The support frame 1 is arranged horizontally or tilted at a slight angle to the horizontal plane.

[0039] like Figure 6 As shown, the positioning plate 21 is a fan-shaped plate, and a first hinge point is provided at the center of the circle of the fan-shaped plate, and the positioning plate 21 can swing around the first hinge point; the first end of the adjustment member 22 is hinged to the first hinge point of the positioning plate 21, and the second end of the adjustment member 22 can be fixedly connected to any adjustment position in a detachable manner; the first end and the second end are respectively the two extended ends of the adjustment member 22. The specific structure is as follows: a plurality of adjustment positions are provided on the positioning plate 21, and the connecting line of the plurality of adjustment positions is an arc surrounding the periphery of the first hinge point. More specifically, a positioning hole penetrating the fan-shaped plate is provided on each adjustment position, and the plurality of positioning holes are evenly distributed on the periphery at the center of the circle. The positioning plate 21 also includes an indicator mark, and an indicator mark is provided at each positioning hole; the adjustment member 22 includes a connecting plate, and the connecting plate includes a first plate and a second plate connected by bending, the angle between the first plate and the second plate is an obtuse angle, and the length of the first plate is greater than the length of the second plate.

[0040] The end of the first plate is hinged at the first hinge point, and the end of the second plate is provided with a socket and a pin. The pin passes through the socket and the positioning hole in sequence to fix the connecting plate and the positioning plate 21 together. The pin and the positioning hole are detachably connected.

[0041] The swing arm 3 is hinged to the other end of the support rod 6, and the ends of the connecting rod 4 are hinged to the middle of the extension of the swing arm 3 and the adjustment member 22. Specifically, the connecting rod 4 is hinged to the middle of the extension of the first plate, and the connecting rod 4 and the adjustment member 22 are hinged at the third hinge point. The connecting rod 4 and the swing arm 3 are hinged at the second hinge point. When the second end of the adjustment member 22 is fixedly connected to different adjustment positions, the distance between the second hinge point and the second end varies. The movable arm 5 can drive the swing arm 3 to swing.

[0042] Furthermore, there are five positioning holes, with the center positioning hole being the zero-gear hole, the first-gear hole and the second-gear hole being located below the zero-gear hole, and the third-gear hole and the fourth-gear hole being located above the zero-gear hole. When the positioning plate 21 is connected to the zero-gear hole, the second hinge point, the third hinge point, and the zero-gear hole are always aligned.

[0043] Adjustment device adjustment as Figure 1State, that is, when the end of the second plate is connected to the first gear hole, the movable arm 5 makes reciprocating motion, and the swing arm 3 makes a balanced shortening of the lever arm swing amplitude as the motion progresses, and the force line produces a slight change from equal weight to gradually reduced weight, that is, from heavy to light, to stimulate the front end of the target muscle group.

[0044] Adjustment device adjustment as Figure 2 State, that is, when the end of the second plate is connected to the second-gear hole, the movable arm 5 makes a reciprocating motion, and the swing arm 3 makes a balanced shortening of the lever arm swing amplitude as the motion progresses, and the force line produces a large change from equal weight to gradually reduced weight, that is, from heavy to light, which effectively improves muscle strength, quickly achieves high-intensity training, makes the muscles quickly congested, and stimulates the front end of the target muscle group with greater intensity.

[0045] Adjustment device adjustment as Figure 3 State, that is, when the end of the second plate is connected to the zero-gear hole, the movable arm 5 makes a reciprocating motion, and the swing arm 3 does not change its swing amplitude with the movement. The force line is a constant weight, that is, an equal weight, so that the target muscle group is stimulated in a balanced manner, which helps to steadily increase muscle strength.

[0046] Adjustment device adjustment as Figure 4 State, that is, when the end of the second plate is connected to the third-gear hole, the movable arm 5 makes a reciprocating motion, and the swing arm 3 makes a balanced lengthening of the force arm swing amplitude as the motion progresses. The force line produces a slight change from equal weight to gradually increasing weight, that is, gradually increasing weight. The action can be corrected when the weight is equal, so that the muscles can be fully warmed up and the terminal muscle groups can be precisely stimulated.

[0047] Adjustment device adjustment as Figure 5 State, that is, when the end of the second plate is connected to the fourth-gear hole, the movable arm 5 makes a reciprocating motion, and the swing arm 3 makes a balanced and lengthened swing of the lever arm as the movement progresses, and the force line produces a change from equal weight to a gradually increasing larger weight, that is, gradually increasing the weight, correcting the training action in the front section, and finding a better feeling of force, and directional stimulation of the terminal muscle groups, so that users with underdeveloped terminal muscles can have a strong explosive force stimulation.

[0048] In summary, the fitness equipment with adjustable force lines provided by the present invention provides a fitness equipment with multiple force lines, which can meet diversified training needs. Through an adjustment device, different angles are adjusted, and the movable arm 5 causes the swing arm 3 providing the weight load to swing differently or with different amplitudes during exercise, that is, the balanced change of the force arm, thereby changing the reduction, constant weight and increase of the training weight. By realizing multiple variable force lines, the trainee can obtain more scientific and refined training by providing multiple variable force lines, meet different training needs, and accurately stimulate target muscle groups in different directions.
