Description

Technical Field

[0001] This application relates to the technical field of fitness equipment, and particularly to a fitness equipment. Background Art

[0002] As a kind of fitness equipment, the arm trainer mainly exercises the flexor muscles of the forearm wrist. At present, the arm trainers on the market often have a single function and are not very convenient for storage. For example, the Chinese utility model patent with the application number CN202122212452.4 discloses an arm trainer, which includes a first arm rod and a second arm rod pivotally connected to the first arm rod. A torsion member is provided at the pivot connection of the first arm rod and the second arm rod. The exercise method is fixed and the function is relatively single. It can only hold the first arm rod and the second arm rod and squeeze them towards the middle. The first arm rod and the second arm rod cannot be folded, which is not convenient for storage and packaging. On the other hand, the strength of the arm trainer cannot be adjusted, and the arm spans of different users are different, so the angles of the first arm rod and the second arm rod cannot be adjusted. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, this application provides a fitness equipment that can effectively solve the above problems.

[0004] The technical solution adopted by this application to solve its technical problems is: a fitness equipment, including: a first arm rod and a second arm rod hinged to the first arm rod. A force application device is provided at the hinge connection of the first arm rod and the second arm rod. The force application device always has a tendency for the ends of the first arm rod and the second arm rod away from the hinge connection to move away from each other. It further includes: an angle adjustment structure for adjusting the maximum movement angle between the first arm rod and the second arm rod; a strength adjustment structure for adjusting the magnitude of the pressing force required between the first arm rod and the second arm rod; a handle assembly detachably provided at the ends of the first arm rod and the second arm rod away from the hinge connection. The handle assembly can be arranged in the extending direction of the first arm rod and the second arm rod, or can be vertically arranged on the first arm rod and the second arm rod.

[0005] In the above technical solution, further, the force application device includes a spring locator, a seat plate and a first elastic member. One end of the first elastic member is a circular ring ear that cooperates with the convex platform of the spring locator. The spring pressing piece is fixedly arranged on the convex platform through a limiting member. The other end of the first elastic member is a straight line segment, and the straight line segment is clamped with the bottom groove of the seat plate. The seat plate passes through the top bushing of the spring and is clamped with the spring locator. A spring inner bushing is sleeved outside the seat plate. One end of the spring inner bushing is clamped with the spring locator, and the other end is clamped with the straight line segment.

[0006] In the above technical solution, further, the angle adjustment structure includes a mounting bracket and a second pull pin. The second arm is rotatably arranged at the center of the seat plate through the mounting bracket. The second pull pin passes through the mounting bracket and cooperates with a positioning card slot circumferentially arranged on the seat plate. The second pull pin cooperates with different positioning card slots to adjust the included angle between the first arm and the second arm.

[0007] In the above technical solution, further, the force adjustment structure includes an upper regulator plate and a lower regulator plate clamped on both sides of the mounting bracket. A limit post is arranged at the end of the lower regulator plate and is clamped with the spring locator. An adjustment gasket is fixedly arranged between the upper regulator plate and the lower regulator plate.

[0008] In the above technical solution, further, connecting pipes are movably arranged at the ends of the first arm and the second arm. First mounting holes are axially arranged on the connecting pipes, and second mounting holes are radially arranged. The handle assembly is in an extended state when cooperating with the first mounting hole, and the handle assembly is in a vertical state when cooperating with the first mounting hole.

[0009] In the above technical solution, further, positioning convex parts are arranged on the connecting pipes and are clamped with different positioning holes of the first arm and the second arm, so that the lengths of the connecting pipes extending out of the first arm and the second arm are different. The positioning convex part includes a detent ball and a second elastic component. The detent ball is kept in a protruding state under the action of the second elastic component and is clamped with the positioning hole to form a fixation.

[0010] In the above technical solution, further, the handle assembly includes a handle body, a third elastic component, a control pin and a steel ball. The steel ball is slidably arranged in a sliding hole of the handle body. The control pin is movably arranged inside the handle body through the third elastic component. The control pin is provided with a top part and a receiving part to cooperate with the steel ball.

[0011] In the above technical solution, further, when the control pin is pushed upward under pressure, the third elastic component is compressed, and the steel ball contacts the receiving part so that the steel ball can be received inside the handle body. When the control pin loses pressure, the first elastic component automatically resets, and the steel ball contacts the top part, so that the steel ball protrudes from the surface of the handle body.

[0012] In the above technical solution, further, a tail plug for clamping is arranged at the bottom of the handle body. The control pin extends out of the tail plug under the action of the third elastic component.
