Description

Technical Field

[0001] The utility model relates to the technical field of fitness equipment, in particular to a rowing machine which is easy to store. Background Art

[0002] As people pay more and more attention to their health, in addition to a proper diet and adequate sleep, proper exercise and fitness are also essential. In order to make exercise and fitness a long-term and effective daily behavior and avoid being affected by factors such as weather conditions as much as possible, most people will use fitness equipment to exercise their bodies, so that people can exercise at home. Most fitness equipment mainly achieves the effect of strengthening strength by setting different resistances. For example, a rowing machine is an aerobic exercise machine that improves comprehensive ability. Its movement is similar to that of a kayak. During exercise, the resistance of water and the change in the speed of the wheel are used in a short period of time to exercise the muscles of the legs, waist, upper limbs and back.

[0003] In the prior art, for example, announcement number CN211885297U proposes a new type of foldable and storable rowing machine, comprising a first base frame and a second base frame that are hinged to each other, the bottom of the second base frame can be folded to fit with the bottom of the first base frame; the first base frame and the second base frame are provided with a first stop column and a handlebar on the side of the first base frame, the handlebar is hinged to the side of the second base frame, and the handlebar is engaged with the first stop column by rotating the handlebar to prevent the folded first base frame and the second base frame from unfolding; the handlebar is also threadedly connected with a twisting member, and the handlebar is driven to move by rotating the twisting member so that the folded first base frame and the second base frame are locked and fixed to each other. The rowing machine is foldable by providing a first base frame and a second base frame that are hinged to each other, which reduces the occupied space and facilitates the placement and storage of the rowing machine after fitness; the first stop column and the handlebar are locked to each other by the twisting member to prevent the folded first base frame and the second base frame from accidentally unfolding and damaging.

[0004] When using the above solution, the trainee needs to pull the folding handle upwards and bring the folding handles inwards with the help of the rollers on both sides after completing the exercise, and when the first base frame and the second base frame are against each other, turn the handle to fix them. However, when a trainee with less strength folds the rowing machine, there will be a problem that he cannot rely on his own strength to pull the folding handles to complete the storage of the rowing machine. Utility Model Content

[0005] The utility model aims to provide a rowing machine that is easy to store, and is mainly used to solve the problem in the prior art that when a trainee with less strength folds the rowing machine, it is impossible to pull the folding handle by his own strength to complete the folding and storage of the rowing machine.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A rowing machine that is easy to store, includes a first base frame, a second base frame and a handle fixedly connected to the inner wall of the second base frame, both sides of the first base frame close to one end of the second base frame are rotatably connected with threaded sleeves, support rods are passed through the threaded sleeves, the threaded sleeves are threadedly connected to the support rods, the upper end of the support rods is connected to a drive box, the upper end of the support rods extends to the interior of the drive box and is rotatably connected to the drive box, a drive assembly is rotatably connected inside the drive box, and the drive assembly is fixedly connected to the upper end of the support rod.

[0008] 1. Working principle: After the trainee completes the exercise, he rotates the support rod to a vertical state, operates the driving assembly to drive the two support rods to rotate downward through the threaded sleeve, so that the bottom of the support rod is against the ground, and continues to operate the driving assembly. The threaded sleeve rotates and moves upward along the support rod, and the threaded sleeve drives the end of the first frame close to the second frame to move upward, and the end of the second frame hinged to the first frame also moves upward. When the bottom of the first frame is against the bottom of the second frame, the handle is turned to fix the first frame and the second frame. The rowing machine is moved to a suitable position through the roller at the bottom of the rowing machine to complete the storage of the rowing machine.

[0009] 2. Beneficial effect: By setting up a driving assembly, the operation of the driving assembly drives the support rod to rotate downward through the threaded sleeve, and the threaded sleeve moves upward along the support rod, and drives the first base frame and the second base frame to move inward and counteract each other at both ends, thereby completing the folding and storage of the rowing machine. When unfolding the rowing machine, the trainee can also slowly unfold the rowing machine by operating the driving assembly, thereby avoiding the situation where the trainee is insufficient in strength to directly pull up or put down the rowing machine.

[0010] Preferably, the driving assembly includes a driving wheel and a driven wheel rotatably connected at both sides of the bottom of the inner wall of the driving box, the upper ends of the two support rods are fixedly connected to the driving wheel and the driven wheel respectively, and belts are sleeved on the driving wheel and the driven wheel. An L-shaped connecting shaft is fixedly connected to the upper end of the driving wheel, and the L-shaped connecting shaft penetrates the driving box and extends out of the driving box. A folding handle is connected to the end of the L-shaped connecting shaft away from the driving box. The training personnel drives the driving wheel to rotate through the L-shaped connecting shaft by rotating the folding handle, and the driving wheel drives the driven wheel to rotate synchronously through the belt. The driving wheel and the driven wheel respectively drive the support rod to rotate, and the support rod is threaded in the sleeve The rowing machine can be folded and stored by rotating the folding handle and moving the threaded sleeve upward along the support rod, so that the trainee only needs to rotate the folding handle to complete the folding of the rowing machine, thereby simplifying the steps of storing the rowing machine. On the other hand, the rowing machine can be slowly unfolded by rotating the folding handle in the opposite direction, thereby avoiding damage caused by the large impact force when the rowing machine is directly unfolded. By providing a folding handle fixedly connected to the L-shaped connecting shaft, the trainee can better fit the natural grip of the hand when rotating the folding handle and help the trainee to better exert force, thereby improving the rotation efficiency of the drive assembly.

[0011] Preferably, a storage groove is provided at the top of the L-shaped connecting shaft, and a rotating shaft passes through the end of the folding handle away from the L-shaped connecting shaft.
