Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a fat-shaking machine. Background Art

[0002] The fat-shaking machine utilizes the principles of balanced lateral motion and amplitude superposition, a principle used in exercise science, to mobilize body fat, consume calories, and eliminate excess body fat. By installing an oscillating mechanism, such as that disclosed in CN211512529U, on the base of the machine, the motor and transmission structure within the oscillating mechanism achieve vibration and side-to-side swinging without requiring the user to move voluntarily. Existing oscillating mechanisms are fixed to the base, and neither the oscillating mechanism itself nor its internal structure enables back-and-forth swinging. This prevents users from performing exercises that rely on the oscillating mechanism to swing back and forth. Utility Model Content

[0003] Aiming at the above problems, the utility model provides a fat-shaking machine which can realize forward and backward swinging.

[0004] The technical solution used by the utility model to solve the above problems is: a fat-shaking machine, including a base, a swinging mechanism and a pedal, the swinging mechanism includes a main frame, the pedal is connected to the upper end of the main frame, downwardly extending connecting arms are provided on both sides of the main frame, two support arms are provided on the base, the connecting arm is located on one side of the support arm, the upper end of the connecting arm is rotatably connected to the upper end of the support arm through a pin shaft, and a locking mechanism is provided between the lower end of the connecting arm and the lower end of the support arm.

[0005] The swing mechanism of the present invention is rotatably connected to the support arm of the base via a connecting arm. The swing mechanism's main frame can tilt and swing back and forth relative to the base, and pedals are mounted on the main frame. With this structure, users standing on the pedals can rock back and forth by exerting their own strength to achieve their exercise goals. Compared to existing technologies, the present invention's swing mechanism can swing back and forth relative to the base, expanding the machine's exercise modes and enriching its functionality.

[0006] Preferably, the lower end of the connecting arm is provided with a first limiting hole, the lower end of the support arm is provided with a matching hole, the locking mechanism includes a locking link, the locking link is inserted into the first limiting hole and the matching hole and can slide axially relative to both, the outer periphery of the locking link is provided with a locking block, the outer diameter of the locking block is less than or equal to the inner diameter of the first limiting hole, the outer diameter of the locking block is smaller than the inner diameter of the matching hole, and the outer diameter of the locking block is larger than the outer diameter of the locking link. After such arrangement, as the locking link slides axially, the locking block can be inserted into or pulled out of the first limiting hole. When the locking block is inserted into the first limiting hole, the locking block fits tightly with the first limiting hole, the locking mechanism is in a locked state, and the connecting arm and the support arm are fixed and cannot rotate. When the locking block is pulled out of the first limiting hole, there is a gap between the locking link and the wall of the first limiting hole, the locking mechanism is in an unlocked state, and the connecting arm and the support arm can rotate within a certain range.

[0007] Preferably, a locking sleeve is provided on the edge of the mating hole and extends away from the connecting arm, and serves as a sliding guide for locking the connecting rod.

[0008] Preferably, a handle is provided at one end of the locking link, and pulling the handle can drive the locking link to slide axially.

[0009] Preferably, two second limiting holes are provided on either side of the first limiting hole in the horizontal direction, intersecting therewith. The first limiting hole has a larger diameter than the second limiting hole, and the second limiting hole has a larger diameter than the outer diameter of the locking link. This arrangement can expand the rotation range of the connecting arm and the support arm, and the first limiting hole is expanded horizontally, without the need to enlarge the locking block.

[0010] Preferably, when the axis of the first limiting hole and the axis of the locking rod link coincide, the angle formed by the tangent line of the arc of the locking rod link through the axis of the pin and the tangent line of the arc of the second limiting hole on the same side through the axis of the pin is less than 15°. This arrangement limits the rotation of the connecting arm and the support arm to a range of ±15°, preventing excessive rotation range from causing tipping during forward and backward swinging motion.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figures 1 to 5 As shown, a fat-shaking machine includes a base 1, a swing mechanism 2, and a pedal 3. The swing mechanism 2 includes a main frame 21, and the pedal 3 is connected to the upper end of the main frame 21. Connecting arms 22 extending downward are provided on both sides of the main frame 21. Two support arms 11 are provided on the base 1. The connecting arm 22 is located on one side of the support arm 11. The upper end of the connecting arm 22 is rotatably connected to the upper end of the support arm 11 through a pin 4. A locking mechanism is provided between the lower end of the connecting arm 22 and the lower end of the support arm 11.

[0019] The lower end of the connecting arm 22 is provided with a first limiting hole 221, and the lower end of the support arm 11 is provided with a matching hole 110. The locking mechanism includes a locking link 5, which is inserted into the first limiting hole 221 and the matching hole 110 and can slide axially relative to both. A handle 52 is provided at one end of the locking link 5. Pulling the handle 52 causes the locking link 5 to slide axially.

[0020] A locking block 51 is provided on the outer periphery of the locking link 5. The outer diameter of the locking block 51 is less than or equal to the inner diameter of the first limiting hole 221. The outer diameter of the locking block 51 is smaller than the inner diameter of the matching hole 110. The outer diameter of the locking block 51 is larger than the outer diameter of the locking link 5. As the locking link 5 slides axially, the locking block 51 can be inserted into or pulled out of the first limiting hole 221. When the locking block is inserted into the first limiting hole 221, the locking block 51 fits tightly with the first limiting hole 221, the locking mechanism is in a locked state, and the connecting arm 22 and the support arm 11 are fixed and cannot rotate. When the locking block 51 is pulled out of the first limiting hole 221, there is a gap between the locking link 5 and the wall of the first limiting hole 221, the locking mechanism is in an unlocked state, and the connecting arm 22 and the support arm 11 can rotate within a certain range.

[0021] The edge of the matching hole 110 is provided with a locking sleeve 111 extending to a side away from the connecting arm 22. The locking sleeve 111 plays a sliding guide role for locking the connecting rod 5.

[0022] Two second limiting holes 222 are provided on either side of the first limiting hole 221 in the horizontal direction, intersecting therewith. The diameter of the first limiting hole 221 is larger than that of the second limiting hole 222, and the diameter of the second limiting hole 222 is larger than the outer diameter of the locking link 5. This arrangement expands the rotation range of the connecting arm 22 and the support arm 11. The first limiting hole 221 is expanded horizontally to both sides, allowing the locking link 5 to move within the second limiting holes 222 without increasing the outer diameter of the locking block 51.

[0023] When the axis of the first limiting hole 221 coincides with the axis of the locking rod link 5, the angle between the tangent line of the arc of the locking rod link 5 passing through the axis of the pin 4 and the tangent line of the arc of the second limiting hole 222 on the same side passing through the axis of the pin 4 is less than 15°. The same side refers to the same side in the horizontal direction of the axis of the first limiting hole 221 and the locking rod link 5. Figure 5 As shown, the tangent line of the arc of the locking rod connecting rod 5 passing through the axis of the pin 4 is line a, and the tangent line of the arc of the second limiting hole 222 passing through the axis of the pin 4 is line b, with ∠ab less than 15°. This arrangement limits the rotation of the connecting arm 22 and the support arm 11 to a range of ±15°, preventing excessive rotation range from causing tipping during forward and backward swinging motion.

[0024] The swing mechanism 2 of the fat-shaking machine of the present invention is rotatably connected to the support arm 11 of the base 1 through the connecting arm 22 on the main frame 21. The main frame 21 of the swing mechanism 2 can tilt and swing back and forth relative to the base 1. The pedal 3 is arranged on the main frame 21. After the user stands on the pedal 3, he can rock back and forth by exerting force on his own to achieve the purpose of exercise, increase the exercise mode of the fat-shaking machine, and enrich the functions of the fat-shaking machine.
