[0010] Preferably, the return member is a tension spring.

[0011] Preferably, the operating rod has a U-shaped structure, and the two ends of the operating rod are located inside the counterweight pot body and at the bottom of the two damping blocks. The two ends of the operating rod are arranged on the counterweight pot body for up and down rotation and cooperate with the damping blocks. A strip-shaped through groove extending up and down is provided on the side of the counterweight pot body corresponding to the position of the operating rod. The operating rod extends outward through the strip-shaped through groove and moves up and down in the strip-shaped through groove.

[0012] Preferably, the damping force of the damping mechanism on the guide column is adjustable.

[0013] Preferably, a first adjusting member is connected to the position of the damping block corresponding to the end of the operating rod, and the first adjusting member is in abutment with the operating rod.

DETAILED DESCRIPTION

[0032] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description.

[0033] This embodiment provides a kettlebell lifting training method, in which corresponding counterweights are assembled on the counterweight kettle body 100 according to the training load requirements, and a damping mechanism is assembled inside the counterweight kettle body 100 to move closer to or farther away from the guide column 200; the counterweight kettle body 100 is slidably mounted on the guide column 200 and is located at the bottom of the guide column 200; while lifting the counterweight kettle body 100, the damping force between the damping mechanism and the guide column 200 is released, and the kettlebell lifting training is performed up and down along the guide column 200; during a training break or after the training, the counterweight kettle body 100 is released, and a damping force is generated between the damping mechanism and the guide column 200, and the counterweight kettle body 100 slowly slides down or maintains the position when the counterweight kettle body 100 is released.

[0034] like Figures 1-13 As shown, this embodiment also provides a kettlebell training device for implementing the above-mentioned training method, comprising a weighted kettle body 100 and a guide post 200. The guide post 200 has a base fixed to its bottom and its upper end passes through the weighted kettle body 100. The weighted kettle body 100 is slidably mounted on the guide post 200. During training, the weighted kettle body 100 is subjected to external force and slides along the guide post 200. A shock-absorbing rubber pad is mounted on the bottom of the guide post 200. The shock-absorbing rubber pad is placed on the base and is caught by the shock-absorbing rubber pad when the weighted kettle body 100 slides to the bottom.

[0035] In the embodiment, the counterweight kettle 100 comprises a front kettle cover 101, a rear kettle cover 102, a front counterweight 103, a rear counterweight 104 and a mounting seat plate 105. The front kettle cover 101 is spliced with the rear kettle cover 102 to form a mounting space therebetween. The mounting seat plate 105 is located in the mounting space and close to the rear kettle cover 102. The rear counterweight 104 is located at the rear side of the rear kettle cover 102 and is locked and fixed with the rear kettle cover 102 at the rear side of the mounting seat plate 105 by a second fastener. The front counterweight 103 is located at the front side of the front kettle cover 101 and is locked and fixed with the front kettle cover 101 at the front side of the mounting seat plate 105 by a first fastener. The front counterweight 103 and the rear counterweight 104 are respectively combined with a handle 106 for the trainer to operate the counterweight kettle 100 during training. The overall weight of the counterweight kettle 100 can be changed by configuring the front counterweight 103 and the rear counterweight 104 with different weights to meet different training purposes. In the embodiment, the counterweight kettle 100 is detachably assembled with a counterweight.

[0036] The guide column 200 is located between the mounting seat plate 105 and the front kettle cover 101. Upper and lower holes are respectively formed in the mounting space at positions corresponding to the guide column 200. The guide column 200 passes through the upper and lower holes. The upper and lower ends of the counterweight kettle 100 are sleeved on the guide column 200 through a shaft sleeve. The shaft sleeve stabilizes the sliding direction of the counterweight kettle 100 along the guide column 200.

[0037] The shaft sleeve of the embodiment comprises a metal outer sleeve 51 and a nylon inner sleeve 52 which are nested with each other. The nylon inner sleeve 52 is sleeved on the guide column 200. The metal outer sleeve 51 and the nylon inner sleeve 52 are locked and fixed on the mounting seat plate 105 in the counterweight kettle 100 by a third fastener. When the counterweight kettle 100 slides up and down, the nylon inner sleeve 52 slides and rubs with the guide column 200. The shaft sleeve with the nylon inner sleeve plays two roles. One is to slide with the guide column to stabilize the sliding direction of the counterweight kettle along the guide column. The other is to generate a certain damping force with the guide column to play a proper damping speed reduction role. However, after being used for a certain period of time, the nylon shaft sleeve is worn out, the inner diameter becomes larger, and the damping of the shaft sleeve fails.

[0038] Further, the counterweight kettle 100 is internally provided with a damping mechanism, a damping action end of the damping mechanism has an applied damping position close to the guide column 200 and a released damping position away from the guide column 200, when close to the guide column 200, a damping force is generated between the damping mechanism and the guide column 200, and when away from the guide column 200, the damping force between the damping mechanism and the guide column 200 is released, so that when the kettle training is performed, the trainer can conveniently release the damping, and when the training is paused or ended, the damping action force can be automatically applied to the guide column 200, the guide column 200 serves as a force receiving component of the damping action force, so as to protect the trainer, prevent the counterweight kettle 100 from rapidly falling down to harm the trainer, and increase the product experience.

[0039] The damping mechanism includes an operating rod 30 and two damping assemblies oppositely arranged on both sides of the guide column 200, each damping assembly includes a damping block 10 pivotally connected inside the counterweight kettle 100 and a return member 20 connected between the counterweight kettle 100 and the damping block 10, the return member 20 acts on the damping block 10 to rotate the damping action end upward to be close to the guide column 200, and the operating rod 30 extends out of the counterweight kettle 100 and is used to drive the damping action ends of the two damping assemblies to rotate downward away from the guide column 200 and switch the damping action end to the released damping position.

[0040] In the embodiment, the damping block 10 is made of nylon material, which has high strength and wear resistance and can ensure the service life of the damping block 10. The middle part of the damping block 10 is pivotally connected to a mounting seat plate 105 inside the counterweight kettle 100 through a horizontal pin shaft 11, the left and right ends of the damping block 10 can rotate up and down about the horizontal pin shaft 11, the damping action end of the damping block 10 is located at a first end close to the guide column 200, and the return member 20 and the operating rod 30 act on a second end of the damping block 10 away from the guide column 200.

[0041] In the embodiment, the return member 20 is a tension spring, which is located below the damping block 10, one end of the tension spring is hung on a hanging rod, the hanging rod is fixedly installed on the mounting seat plate 105, and the other end of the tension spring is connected to the second end of the damping block 10 through a first pull pin.

[0042] In this embodiment, the operating rod 30 has a U-shaped structure. The two ends of the operating rod 30 are located inside the counterweight pot body 100 and at the bottom of the two damping blocks 10. The two ends of the operating rod 30 are rotatably mounted on the mounting base plate 105 of the counterweight pot body 100. The operating rod 30 includes a rod body and a movable shaft 31 connected to the two ends of the rod body. The mounting base plate 105 is fixedly connected to a fixed shaft 32 at a position corresponding to the movable shaft 31. The movable shaft 31 has a U-shaped groove at one end away from the rod body. The end of the fixed shaft 32 is protruded with a convex plate that matches the U-shaped groove. The convex plate is inserted into the U-shaped groove and is movably connected via a second horizontal pin. In this way, the operating rod 30 can rotate up and down, and the two ends of the operating rod 30 are in contact with the bottom of the damping block 10.

[0043] The front counterweight 103 and the front pot cover 101 are provided with a strip-shaped through slot 107 extending up and down at the position of the operating rod 30. The operating rod 30 extends outward through the strip-shaped through slot 107 and moves up and down in the strip-shaped through slot 107. The rod part of the operating rod 30 extending out of the counterweight pot body 100 is located below the handle 106 so that the trainee can directly and quickly operate the operating rod 30. When the user holds the handle 106 and the operating rod 30 together with one hand, the operating rod 30 is pulled upward relative to the fixed shaft 32. When the second end of the damping block 10 is subjected to the upward pulling force of the operating rod 30, the return member 20 is stretched and the damping block 10 rotates around the horizontal pin 11, so that the damping action end of the damping block 10 rotates downward away from the guide column 200, thereby releasing the damping force on the guide column 200 and not affecting the trainee's reciprocating kettlebell training along the guide column 200. During the training break or after the training, after releasing the operating rod 30, the damping action end of the damping block 10 rotates upward toward the guide column 200 under the pulling action of the return member 20, and generates a damping force with the guide column 200 again. The damping force is used to maintain the relative position of the counterweight kettle body 100 and the guide column 200 when the release is performed, or to reduce the falling speed of the counterweight kettle body 100, thereby protecting the trainee. The damping force mainly comes from the pull-back force of the return member 20 and the friction force between the damping end and the guide column 200 . A tension spring with different spring stiffness coefficients is selected according to actual conditions and requirements.

[0044] In addition, since the damping block 10 wears out after a period of use, the damping force between the damping block 10 and the guide column 200 decreases and the expected damping effect cannot be achieved. At the same time, it is also convenient to install and debug the damping block 10. The damping mechanism of this embodiment can adjust the damping force of the guide column 200.

[0045] Specifically, the damping block 10 is connected to a first adjusting member 12 at a position corresponding to the end of the operating rod 30. The first adjusting member 12 abuts against the operating rod 30, and the damping force of the damping block 10 is adjusted by adjusting the vertical spacing between the end of the operating rod 30 and the damping block 10 through the first adjusting member 12. The first adjusting member 12 is an adjusting screw. Rotating the adjusting screw changes the length of the rod protruding downward from the bottom of the damping block 10, thereby adjusting the vertical spacing between the end of the operating rod 30 and the damping block 10. Rotating the first adjusting member 12 downward increases the vertical spacing and reduces the angle at which the return member 20 pulls back to drive the damping block 10 to rotate upward, thereby reducing the damping force. Conversely, rotating the first adjusting member 12 downward increases the angle at which the damping block 10 rotates upward and increases the damping force.

[0046] In addition, the damping mechanism also includes a second adjustment member 41, which is located below both ends of the operating rod 30 and engages with the operating rod 30. The second adjustment member 41 is used to adjust the horizontal height at which the operating rod 30 stops falling after being released. The second adjustment member 41 is an adjustment bolt. A second fixed shaft 42 is fixedly connected to the mounting plate 105 at a position corresponding to the second adjustment member 41. The adjustment bolt is threadedly connected to the second fixed shaft 42. Rotating the adjustment bolt changes the length of the rod body that protrudes upward from the top of the second fixed shaft 42, thereby adjusting the horizontal height at which the operating rod 30 stops falling after being released. Generally, the second adjustment member 41 is used to keep the operating rod 30 horizontal after being released. Furthermore, when necessary, the second adjusting member 41 can also cooperate with the first adjusting member 12 to adjust the damping. When the second adjusting member 41 is adjusted upward, the operating rod 30 will be lifted upward. At this time, the horizontal height at which the first adjusting member 12 stops falling will also become higher, and the damping will become smaller. Conversely, when the second adjusting member 41 is adjusted downward, the operating rod 30 will be driven downward. At this time, the horizontal height at which the first adjusting member 12 stops falling will also become lower, and the damping will become larger.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
