Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of training equipment, and particularly relates to a damping mechanism of a kettle-lifting trainer. Background Art
[0002] A kettle-lifting trainer is a training equipment provided for a trainer to exercise muscle groups such as the arms. Generally, the kettle-lifting trainer on the market is a kettlebell. When using such a kettle-lifting trainer, the trainer is required to hold it steadily. Once the hand slips, the kettlebell will quickly fall, and the kettlebell has a large weight, so the probability of being injured by hitting is relatively high. Under this background, the applicant has researched and developed a new type of kettle-lifting trainer, and this type of kettle-lifting trainer is equipped with a damping anti-falling structure, which helps to improve the training safety. Content of the Utility Model
[0003] The purpose of the utility model is to provide a damping mechanism of a kettle-lifting trainer, which can automatically apply a damping force when the training is paused or ended, so as to protect the trainer and prevent the whole from quickly falling due to letting go, thereby injuring the trainer and increasing the product experience.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The damping mechanism of the kettle-lifting trainer includes two relatively arranged damping blocks, a return member acting on each damping block to make the damping block rotate upward, and a U-shaped operating rod acting on the two damping blocks to make the damping block rotate downward. The damping block is pivotally connected inside the kettle-lifting trainer, and the U-shaped operating rod extends outside the kettle-lifting trainer.
[0006] Preferably, the return member adopts a tension spring.
[0007] Preferably, the damping block is made of nylon material.
[0008] Preferably, both ends of the U-shaped operating rod are located at the bottom of the damping block and are in contact and cooperation with the bottom of the damping block. The up-and-down movement of both ends of the U-shaped operating rod drives the damping block to rotate downward.
[0009] Preferably, both ends of the U-shaped operating rod are rotatably arranged up and down inside the kettle-lifting trainer.
[0010] Preferably, the damping force of the damping block is adjustable.
[0011] Preferably, a first adjusting member is connected to the position of the damping block corresponding to the U-shaped operating rod. The first adjusting member is in contact and cooperation with the U-shaped operating rod. The damping force of the damping block is adjusted by adjusting the up-and-down distance between the end of the U-shaped operating rod and the damping block.
[0012] Preferably, the damping mechanism further includes a second adjusting member, which is located below both ends of the U-shaped operating rod and abuts against the U-shaped operating rod, and the horizontal height at which the U-shaped operating rod stops falling after being released is adjusted by the second adjusting member.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The damping mechanism of the utility model includes damping blocks, a return member acting on each damping block to rotate the damping block upward, and a U-shaped operating rod acting on two damping blocks to rotate the damping block downward. When the damping block is subjected to the upward pulling force of the U-shaped operating rod, the damping block rotates, causing the damping action end of the damping block to rotate downward and away from the stressed component, releasing the damping force on the stressed component without affecting the lifting training of the trainer; when the U-shaped operating rod is released, under the pulling action of the return member, the damping action end rotates upward and approaches the stressed component, generating a damping force with the guide post again and using this damping force to maintain the position or reduce the falling speed, protecting the trainer.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to make the above features and advantages of the utility model more obvious and understandable, the following specific embodiments are given and described in detail in conjunction with the accompanying drawings.
[0023] AsFigures 1 - 6 As shown in the figure, this embodiment provides a damping mechanism for a kettle-lifting trainer, which is installed and applied in the kettle-lifting trainer. The kettle-lifting trainer includes a weighted kettle body 101 and a guide post 102. The bottom of the guide post 102 is fixed with a base, and the upper end passes through the weighted kettle body 101. The weighted kettle body 101 slides up and down along the guide post 102. The damping mechanism of this embodiment is to enable the trainer to conveniently release the damping when lifting the kettle during training and automatically apply a damping force to the guide post 102 when the training is paused or ended. The guide post 102 serves as the force-receiving component of the damping force, protecting the trainer from the overall rapid fall of the weighted kettle body 101 due to letting go, and enhancing the product experience.
[0024] The damping mechanism of this embodiment includes two damping blocks 10 arranged oppositely on both sides of the guide post 102, a return member 20 acting on each damping block 10 to rotate the damping block 10 upward, and a U-shaped operating rod 30 acting on the two damping blocks 10 to rotate the damping block 10 downward. The damping block 10 is pivotally connected inside the weighted kettle body 101 of the kettle-lifting trainer. The U-shaped operating rod 30 extends outside the weighted kettle body 101 of the kettle-lifting trainer. The U-shaped operating rod 30 extends outside the weighted kettle body 101 so that the trainer can directly and quickly operate the U-shaped operating rod 30. Generally, in order to facilitate the trainer to lift the weighted kettle body 101, handles 103 are respectively installed and fixed on both sides outside the weighted kettle body 101. The U-shaped operating rod 30 of this embodiment is located below one of the handles 103. When holding the two handles 103 with both hands, the trainer can also well grasp the U-shaped operating rod 30 and lift it upward.
[0025] In this embodiment, the damping block 10 is made of nylon material. The nylon material has high strength and wear resistance, which can ensure the service life of the damping block 10. The middle part of the damping block 10 is pivotally connected inside the weighted kettle body 101 through a horizontal pin shaft 11. The left and right ends of the damping block 10 can rotate up and down around the horizontal pin shaft 11. The damping action end of the damping block 10 is located at the first end of the damping block 10 close to the guide post 102. The return member 20 and the U-shaped operating rod 30 act on the second end of the damping block 10 away from the guide post 102 respectively.
[0026] Specifically, the return member 20 in this embodiment adopts a tension spring. The tension spring is located below the damping block 10. One end of the tension spring is hung on a hanging rod, and the hanging rod is fixedly installed inside the counterweight kettle body 101. The other end of the tension spring is connected to the second end of the damping block 10 through a first pull pin. When an upward pulling force is applied to the second end of the damping block 10 by the U-shaped operating rod 30, the tension spring is stretched, and at the same time, the damping block 10 rotates around the horizontal pin shaft 11, so that the damping action end of the damping block 10 rotates downward away from the guide post 102, releasing the damping force on the guide post 102 without affecting the trainer's pulling training. When the U-shaped operating rod 30 is released, under the pulling-back action of the tension spring, the damping action end of the damping block 10 rotates upward close to the guide post 102, generating a damping force with the guide post 102 again and using this damping force to maintain the relative position of the counterweight kettle body 101 and the guide post 102 or reduce the falling speed of the counterweight kettle body 101 to protect the trainer. The damping force mainly comes from the pulling-back force of the return member 20 and the frictional force between the damping action end and the guide post 102. A tension spring with different spring stiffness coefficients is selected according to the actual situation and requirements.
[0027] Specifically, both ends of the U-shaped operating rod 30 are located at the bottom of the damping block 10, and the up-and-down movement of both ends of the U-shaped operating rod drives the damping block to rotate downward. In this embodiment, both ends of the U-shaped operating rod 30 are respectively rotatably arranged up and down inside the counterweight kettle body 101 of the kettle lifting trainer. The U-shaped operating rod 30 includes a rod main body and movable shafts 31 connected to both ends of the rod main body. Fixed shafts 32 are respectively fixedly connected to the positions corresponding to the movable shafts 31 inside the counterweight kettle body 101. A U-shaped groove is formed at the end of the movable shaft 31 far from the rod main body, and a convex plate adapted to the U-shaped groove protrudes from the end of the fixed shaft 32. The convex plate is inserted into the U-shaped groove and movably connected through a second horizontal pin shaft, so as to realize the up-and-down rotation of the U-shaped operating rod 30. The two ends of the U-shaped operating rod 30 are in abutting cooperation with the bottom of the damping block 10. Therefore, when grasping the handle 103 and the U-shaped operating rod 30 with one hand during training, it will drive the U-shaped operating rod 30 to be pulled upward relative to the fixed shaft 32, and at the same time, it will drive the second end of the damping block 10 to rotate upward and the damping action end to rotate downward, thereby releasing the damping force on the guide post 102.
[0028] Further, on the one hand, to facilitate the installation and debugging of the damping block 10, and on the other hand, to facilitate debugging when wear occurs during after-sales use, resulting in a decrease in damping, the damping force of the damping block 10 in this embodiment is designed to be adjustable. Specifically: A first adjusting member 12 is connected to the damping block 10 at a position corresponding to the U-shaped operating rod 30. The first adjusting member 12 is in abutting cooperation with the U-shaped operating rod 30. By adjusting the first adjusting member 12, the vertical distance between the end of the U-shaped operating rod 30 and the damping block 10 is adjusted to adjust the damping force of the damping block 10. The first adjusting member 12 is an adjusting screw. By rotating the adjusting screw, the length of the rod body protruding downward relative to the bottom of the damping block 10 is changed, so as to adjust the vertical distance between the end of the U-shaped operating rod 30 and the damping block 10. When the first adjusting member 12 is rotated downward, the vertical distance is increased, and the angle at which the return member 20 pulls the damping block 10 upward to rotate is reduced, thereby reducing the damping force. On the contrary, the angle at which the damping block 10 rotates upward is increased and the damping force is increased.
[0029] In addition, the damping mechanism further includes a second adjusting member 41. The second adjusting member 41 is located below both ends of the U-shaped operating rod 30 and is in abutting cooperation with the U-shaped operating rod 30. By adjusting the second adjusting member 41, the horizontal height at which the U-shaped operating rod 30 stops falling after being released is adjusted. The second adjusting member 41 is an adjusting bolt. A second fixed shaft 42 is fixedly connected to the inside of the counterweight kettle body 101 corresponding to the position of the second adjusting member 41. The adjusting bolt is threadedly connected to the second fixed shaft 42. By rotating the adjusting bolt, the length of the rod body protruding upward relative to the top of the second fixed shaft 42 is changed, so as to adjust the horizontal height at which the U-shaped operating rod 30 stops falling after being released. Generally, the U-shaped operating rod 30 is made horizontal after being released by the second adjusting member 41. Furthermore, when necessary, the second adjusting member 41 can also cooperate with the first adjusting member 12 to jointly adjust the damping. When the second adjusting member 41 is adjusted upward, the U-shaped operating rod 30 will be lifted upward. At this time, the horizontal height at which the first adjusting member 12 stops falling is also increased, and the damping will become smaller; on the contrary, when the second adjusting member 41 is adjusted downward, the U-shaped operating rod 30 will be driven downward. At this time, the horizontal height at which the first adjusting member 12 stops falling is also decreased, and the damping will become larger.
