[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1-4 A high-safety weightlifting barbell includes a bracket 2 arranged on one side of a lying plate 1; a protective component is provided on the surface of the bracket 2; the interior of the protective component includes an L-shaped rod 3 symmetrically arranged on the surface of the bracket 2, and a barbell body 4 is placed on the surface of the L-shaped rod 3; a protective plate 5 is connected to one side of the L-shaped rod 3, and a slide groove 6 is symmetrically provided on one side of the protective plate 5, and a slider 7 connected to the L-shaped rod 3 is slidably connected inside the slide groove 6, a mounting groove 8 is provided on the top of the protective plate 5, and a through groove 9 is provided on one side of the inner wall of the mounting groove 8, a connecting rod 12 is connected to the inside of the mounting groove 8, and the top of the connecting rod 12 is connected to the top plate 1 0, a movable groove 11 is provided at the connection center of the top plate 10 and the protective plate 5. The movable grooves 11 on the surface of the protective plate 5 on the L-shaped rods 3 on both sides are convenient for limiting the counterweight plates at both ends of the barbell body 4. The limitation here means that after the barbell body 4 loses balance, the counterweight plates at both ends will not pass from one side of the movable groove 11 to the other side, which ensures the physical safety of the personnel. The cross-sectional area of ​​the connecting rod 12 is equal to or slightly smaller than the cross-sectional area of ​​the mounting groove 8, so that after the connecting rod 12 is moved to the inside of the mounting groove 8, the positioning rod 15 can be located on one side of the through groove 9, which is convenient for installing the top plate 10 and the protective plate 5.

[0030] Furthermore, the counterweight plate at one end of the barbell body 4 is located on one side of the protective plate 5, and the radius of the counterweight plate of the barbell body 4 is greater than the length of the movable slot 11. The movable slot 11 has a certain length. When lifting the barbell body 4, the flexion and extension of the person's arms will not be restricted in any way, but the counterweight plate on the barbell body 4 cannot pass from one side of the movable slot 11 to the other side, thereby preventing the barbell from causing harm to the person after losing balance.

[0031] Furthermore, a spring 13 is connected to the inside of the connecting rod 12, and a movable plate 14 is connected to one side of the spring 13. A positioning rod 15 connected to the through slot 9 is connected to one side of the movable plate 14. Through the action of the spring 13, the top rod positioning rod 15 on one side of the movable plate 14 connected thereto can be connected to the inside of the through slot 9, so that the top plate 10 and the protective plate 5 can be installed, and vice versa, it is also convenient to disassemble them.

[0032] Furthermore, the L-shaped rod 3 is rotatably connected to a screw 16, and moving blocks 17 are respectively threadedly connected on both sides of the surface of the screw 16. The surface of the moving block 17 is connected to a support bar 18 through a movable shaft, and one end of the support bar 18 is connected to a pad 19 through a movable shaft. The top of the pad 19 is connected to a buffer plate 20. In order to better protect the personnel, the height of the barbell body 4 can be adjusted according to the height of the exerciser lying on the lying board 1 to prevent the barbell body 4 from causing injury to the personnel after falling. By rotating the screw 16, the moving blocks 17 at both ends of its surface can drive the support bar 18 to move, and the pad 19 and the buffer plate 20 at the top can be moved to a specified height through the support bar 18, so that the barbell body 4 on the buffer plate 20 can be moved to a specified height. The moving block 17 is slidably connected to the inner wall of the L-shaped rod 3, and the pad 19 is slidably connected to the L-shaped rod 3 and the bracket 2.

[0033] Furthermore, the threads at both ends of the screw rod 16 are arranged in opposite directions, so that when the screw rod 16 rotates, the moving blocks 17 on both sides of the surface thereof can move toward each other or move away from each other at the same time.

[0034] Furthermore, the buffer plate 20 is a rubber buffer plate 20 , which has good elasticity and energy absorption capacity, can effectively absorb impact force, and reduce the vibration and impact caused by the barbell body 4 to the L-shaped rod 3.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
