The hanging rods 1201, which are equidistantly arranged longitudinally on the brackets 12, are specifically used to hang barbell plates 13. During training, users can hang barbell plates 13 of different weights on the hanging rods 1201 according to the training intensity requirements, making it easy to quickly select and replace them, and avoiding the cluttered space and inconvenience of access caused by the random placement of barbell plates 13. At the same time, the symmetrical arrangement of the brackets 12 and hanging rods 1201 and the barbell plates 13 thereon ensure the balance and stability of the entire device. The design of the equidistant distribution of the hanging rods 1201 longitudinally also makes the storage and access of the barbell plates 13 more orderly, greatly improving the convenience and efficiency of training and meeting the weight requirements of diversified strength training.

[0025] In the present invention, the protective mechanism 6 also includes a shell 607 with a closed top and an open bottom. The bottom of the shell 607 is snap-fitted and installed above the hanging rod 503.

The end of the housing 607 near the grip 502 partially overlaps and is closed with the grip 502. The second movable opening 502b opened at the top of the overlap allows the trapezoidal block 706 to move up and down, and the trapezoidal block 706 The top extends into the shell 607 through the second movable opening 502b and abuts against the round rod 603. When the pressing block 701 of the unlocking mechanism 7 is pressed, the trapezoidal block 706 moves upward to push the round rod 603, so that the blocking block 601 disengages from the horizontal groove 301 of the vertical rod 3, thereby unlocking the height adjustment of the barbell bar 5; after releasing the pressing block 701, the first spring 606 resets and drives the round rod 603 and the blocking block 601 to re-engage the horizontal groove 301. The other end of the shell 607 is open and fixed to the side wall of the sliding seat 4, ensuring that the protective mechanism 6 is firmly connected to the overall structure, thereby ensuring the stable operation of the protection and unlocking functions.

[0027] In the present invention, a horizontally arranged movable groove 401a is provided on the sleeve 401 for 601 to move left and right. The top of the pressing block 701 is in contact with the inner wall of the first movable opening 502a. The bottom of the pressing block 701 is an arc-shaped structure for easy grasping, and the pressing block 701 and the shell 607 are staggered with each other.

[0028] In this embodiment, the transverse movable groove 401a provided on the sleeve 401 provides space for the clamping block 601 to move left and right, allowing the clamping block 601 to smoothly insert or remove from the transverse groove 301 of the vertical rod 3, thereby ensuring the normal operation of the protective mechanism 6. The top of the pressing block 701 is tightly fitted with the inner wall of the first movable opening 502a at the bottom of the grip 502, preventing the pressing block 701 from shaking while ensuring the accurate transmission of the pressing action. The curved structure at the bottom facilitates the trainee's grip and force application, conforming to the ergonomic design and improving operational comfort. At the same time, the pressing block 701 and the housing 607 are staggered, rationally utilizing the spatial layout to avoid interference between the two during movement. This allows the pressing block 701 to push the round rod 603 to unlock smoothly and unimpeded through the operating lever 705 and the trapezoidal block 706, thereby achieving convenient control of the protective mechanism 6 and providing reliable protection for the trainee to flexibly adjust the height of the barbell 5.

[0029] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
