Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a rowing machine. Background Technology

[0002] A rowing machine is a machine designed for training purposes, used to simulate rowing on water. Rowing machines are effective in strengthening the muscles of the legs, waist, upper limbs, chest, and back. With each stroke, the upper limbs, lower limbs, waist, abdomen, and back complete a full contraction and extension, achieving a full-body aerobic exercise effect.

[0003] A typical rowing machine generally includes a support frame, slide rails, seat, water resistance mechanism, tensioning mechanism, and reset mechanism. The tensioning mechanism includes a positioning wheel, elastic rope, and a first guide wheel. The reset mechanism includes a second guide wheel and an elastic band. The positioning wheel is mounted on the shaft of the water resistance mechanism. One end of the elastic band is fixed and wound around the positioning wheel, and the other end is wound around the first guide wheel located above the second guide wheel. A handle is located at the second end of the elastic band, which is movably engaged with a hook on the support frame. One end of the elastic rope is fixed to the positioning wheel, and the other end is wound around the second guide wheel, which is arranged laterally, and then fixedly connected to the support frame. During use, it was found that the elasticity of the reset mechanism cannot be adjusted according to different exercise intensities, thus its practicality needs improvement. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1-3 As shown, this utility model provides a rowing machine, including a main body 100. The main body 100 includes a support platform 1, on which a tensioning mechanism 2 and a reset mechanism 3 are mounted. The reset mechanism 3 includes a first guide wheel 31, a first elastic element 32, and a second guide wheel 33. The first guide wheel 31 and the second guide wheel 33 are disposed opposite each other on the support platform 1. The first guide wheel 31 has at least one first positioning part 31a spaced vertically along its upper edge, and the second guide wheel 33 has at least one second positioning part 33a spaced vertically along its upper edge. One end of the first elastic element 32 is connected to the tensioning mechanism 2, and the first elastic element 32 is respectively wound around the first positioning part 31a and the second positioning part 33a, and its second end is detachably connected to at least one of the tensioning mechanism 2, the first guide wheel 31, the second guide wheel 33, and the support platform 1. The first guide wheel 31 includes a lower positioning post and a grooved wheel disposed on the upper part of the positioning post to prevent the grooved wheel from deforming under force.

[0028] like Figure 2 , 3 As shown, the diameters of the positioning parts on each guide wheel and positioning wheel can be the same or different, and the diameters of the corresponding positioning parts on a single guide wheel and positioning wheel can be the same or different. This makes the winding scheme of the first elastic element 32 more versatile.

[0029] The second end of the first elastic element 32 is provided with a buckle 34, which is detachably mounted on one of the tensioning mechanism 2, the first guide wheel 31, the second guide wheel 33, and the support platform 1. The buckle 34 is a carabiner, or it may have a locking hole on the guide wheel or the support platform 1. The first elastic rope 32 is provided with a hook, which can be detachably mounted on the locking hole.

[0030] The tensioning mechanism 2 includes a positioning wheel 21 and a second elastic element 22. The main body 100 includes a rotating shaft 5 passing through the support platform 1. The rotating shaft 5 is mounted on the resistance mechanism 9 of the main body 100. The positioning wheel 21 is mounted on the rotating shaft 5 and has a fourth positioning part 21a and at least one fifth positioning part 21b vertically offset along its upper edge. One end of the second elastic element 22 is fixed to the positioning wheel 21, and the second elastic element 22 is wound around the fourth positioning part 21a. A handle 6 is provided on its other end. One end of the first elastic element 32 is fixed to one of the fifth positioning parts 21b. At least one first guide wheel 31 and a second guide wheel 33 are respectively provided on both sides of the positioning wheel 21. The first elastic element 32 is located below the second elastic element 22. The first elastic element 32 is an elastic rope, and the second elastic element 22 is an elastic band.

[0031] The support platform 1 is equipped with two opposing limiting posts 7. The free end of the second elastic element 22 is located between the two limiting posts 7. The handle 6 is movably locked onto one side of the two limiting posts 7. A bracket 8 for placing electronic products is installed on the support platform 1. The bottom of the bracket 8 and the limiting posts 7 are installed on the support platform 1 with screws. The bracket 8 has a notch for the second elastic element 22 to pass through, and it also prevents the second elastic element 22 from shifting to the left or right and disengaging from the limiting posts 7 when the user pulls the second elastic element 22 back and forth due to instability, thus restricting the user's improper movements.

[0032] like Figure 1 , 2 As shown, the support platform 1 includes a base plate 11, two side plates 12 and a top plate 13. The first guide wheel 31, the positioning wheel 21, the second guide wheel 33 and the third guide wheel 4 are installed on the base plate 11, and the fourth guide wheel 23, the bracket 8 and the limiting column 7 are installed on the top plate 13.

[0033] A third guide wheel 4 is mounted on the support platform 1. At least one third positioning part 4a is provided on the upper edge of the third guide wheel 4 in a vertical direction. The second end of the first elastic member 32 is mounted on one of the third positioning parts 4a. A seventh positioning part 4b is also provided on the upper edge of the third guide wheel 4 in a vertical direction, which is offset from the third positioning part 4a. The second elastic member 22 is wound around the seventh positioning part 4b and the sixth positioning part 23a in sequence. The third guide wheel 4 is located between the positioning wheel 21 and the fourth guide wheel 23.

[0034] like Figure 2-3 As shown, the tensioning mechanism 2 also includes a fourth guide wheel 23, which is mounted on the support platform 1. The fourth guide wheel 23 has a sixth positioning part 23a, and the second elastic element 22 is wound around the sixth positioning part 23a. The fourth guide wheel 23 is located above the first guide wheel 31 and is arranged laterally.

[0035] The positioning wheel 21, the first guide wheel 31, and the third guide wheel 4 are provided with flanges 10 in the middle to form two positioning parts located on the upper and lower parts of the corresponding wheel bodies, respectively. The height of the positioning wheel 21 and each guide wheel, as well as the position, number, and height of the corresponding positioning parts on the positioning wheel 21 and each guide wheel, should be such that the winding of the first elastic member 32 and the second elastic member 22 does not interfere with each other.

[0036] As one way the first elastic element 32 is wound, two first guide wheels 31 and two second guide wheels 33 are provided. One end of the first elastic element 32 is connected to the flange 10 of the positioning wheel 21. It is wound around the first positioning part 31a on the upper part of the two first guide wheels 31 from the side of the first guide wheel 31 away from the third guide wheel 4 (i.e., the outside of the first guide wheel 31). Then it is wound around the second positioning part 33a on the second guide wheel 33 from the side of the second guide wheel 33 away from the positioning wheel 21. Then it is wound around the first positioning part 31a on the lower part of the two first guide wheels 31 from the outside of the first guide wheel 31. Finally, it is hooked onto the third positioning part 4a of the third guide wheel 4 by the latch 34.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
