[0033] Example 1

[0034] Reference Figure 1-7 , which is the first embodiment of the present utility model, provides a barbell plate device, including a barbell assembly 1, the barbell assembly 1 includes a barbell 11, symmetrical sliding grooves 13 provided at both ends of the inner cavity of the barbell 11, and symmetrical limiting grooves 14 provided on the upper end surface of the barbell 11;

[0035] A protective assembly 2 is arranged on the outer wall of the barbell 11, and the protective assembly 2 includes a protective pad 21 arranged on the outer wall of the barbell 11, a connecting rod 22 inserted into the inner wall of 13, an adjusting chamber 23 opened at one end of the connecting rod 22, a first sliding rod 24 arranged at both ends of the inner wall of the adjusting chamber 23, a first spring 25 sleeved on the outer wall of the first sliding rod 24, a first sliding block 26 sleeved on the outer wall of the first sliding rod 24, an adjusting rod 27 arranged at the upper end of the first sliding block 26, and a limit plate 28 arranged at both ends of the inner wall of 23, and the limit plate 28 passes through the upper end surface of the limit groove 17, the connecting rod 22 is slidably inserted into the inside of the slide groove 13, the first sliding block 26 is slidably sleeved on the outer wall of the first sliding block 24, the upper and lower ends of the adjusting rod 27 are hinged to the limit plate 28 and the first sliding block 26 respectively, and both ends of the limit plate 28 are rotatably connected to the inner wall of the adjusting chamber 23.

[0036] When the protective pad 21 needs to be replaced or maintained, the limit plate 28 can be pressed downward to press the limit plate 28 below the limit groove 14. Since the limit plate 28 is rotatably connected to the inner wall of the adjustment chamber 23, the limit plate 28 is rotated to be parallel to the upper end surface of the plug rod 22, and since the upper and lower ends of the adjustment rod 27 are hinged to the limit plate 28 and the first slider 26, under the action of the limit plate 28, the adjustment rod 27 drives the first slider 26 to slide along the first slide rod 24 and compresses the first spring 25. At this time, the plug rod 22 is pulled out along the slide groove 13, and then the protective pad 21 that needs maintenance is maintained and replaced. After the protective pad 21 is replaced, the plug rod 22 can be aligned with the slide groove 13 and inserted. When the limit plate 28 contacts the slide groove 13, the limit plate 28 gradually rotates downward. The first spring 25 is pressed against the first slide 26 and the second spring 26 is pressed against the first slide 26, and the first slide 26 is pressed against the first slide 26. When the first slide 26 is pressed against the first slide 26, the first slide 26 is pressed against the first slide 26. When the first slide 26 is pressed against the first slide 26, the first slide 26 is pressed against the first slide 26. When the first slide 26 is pressed against the first slide 26, the first slide 26 is pressed against the first slide 26. When the first slide 26 is pressed against the first slide 26, the first slide 26 is pressed against the first slide 26. When the first slide 26 is pressed against the first slide 26, the first slide 26 is pressed against the first slide 26.

[0037] Example 2

[0038] Reference Figure 1-8 , which is the second embodiment of the present utility model. This embodiment differs from the first embodiment in that: a receiving ring 17 is provided on the lower end surface of the barbell 11; four sets of fixing components 3 are provided symmetrically in the inner cavity of the barbell 11; and a connecting tube 4 is provided on the upper end surface of the receiving ring 17;

[0039] The barbell assembly 1 further includes protrusions 12 provided on the upper and lower end surfaces of the barbell 11, and there are four groups of protrusions 12, and two groups of protrusions 12 on the same plane are symmetrical to each other;

[0040] The barbell assembly 1 further includes four sets of mutually symmetrical first cavities 15 and second cavities 16 defined within the interior of the barbell 11, and four sets of mutually symmetrical threaded grooves 19 disposed on the upper end surface of the barbell 11. The fixing assembly 3 includes a first wedge-shaped block 31 slidably disposed on the inner wall of the first cavity 15, and a fixing rod 32 disposed on one side of the first wedge-shaped block 31, with one end of the fixing rod 32, away from the first wedge-shaped block 31, extending through the barbell 11 and positioned within the second cavity 16.

[0041] The fixing assembly 3 also includes a fixing block 33 provided on the inner wall of the second cavity 16, and one end of the fixing block 33 is fixedly connected to the fixing rod 32, a second spring 34 is sleeved on the outer wall of the fixing rod 32, and the two ends of the second spring 34 are respectively fixedly connected to the first wedge block 31 and the first cavity 15; the fixing assembly 3 also includes a second sliding rod 35 provided on the upper and lower end surfaces of the first cavity 15, a second slider 36 slidably sleeved on the outer wall of the second sliding rod 35, a second wedge block 37 provided on one side of the second slider 36, and the contact surface of the second wedge block 37 and the first wedge block 31 are parallel to each other, a bolt 38 is provided on the upper end of the second wedge block 37, and the lower end of the bolt 38 is threadedly inserted into the interior of the thread groove 19;

[0042] The barbell assembly 1 further includes a plug-in slot 18 formed around the upper end surface of the barbell 11. The outer wall of the connecting tube 4 is provided with four symmetrical sets of limit plugs 5, and the limit plugs 5 are movably inserted into the inner wall of the plug-in slot 18.

[0043] During the long-term contact between the connecting tube 4 and the barbell bar, the connecting tube 4 is worn. In order to increase the stability of the contact between the connecting tube 4 and the barbell bar, when the connecting tube 4 needs to be replaced, the threaded bolt 38 can be rotated to remove the threaded bolt 38 from the threaded groove 19. At this time, under the reverse elastic force of the second spring 34, the first wedge block 31 slides along the first cavity 15, and the first wedge block 31 drives the fixing rod 32 and the fixing block 33 to slide toward the second cavity 16. Since the contact surfaces of the first wedge block 31 and the second wedge block 37 are parallel to each other, the lower end inclined surface of the second wedge block 37 slides along the first wedge block 31, and the second wedge block 37 drives and The second slider 36 slides upward along the second slide rod 35. At this time, the fixing block 33 releases the lock on the connecting tube 4, and the connecting tube 4 can be taken out for replacement and maintenance. When the replaced connecting tube 4 needs to be installed on the middle end of the barbell plate 11, it can be inserted into the insertion groove 18 through the limiting plug block 5, and the connecting tube 4 is placed on the upper end of the receiving ring 17. At this time, the threaded bolt 38 is rotated, and the threaded bolt 38 compresses the second slider 36 downward along the threaded groove 19. The second slider 36 moves downward along the second slide rod 35, so that the lower end face of the second wedge block 37 slides along the upper end face of the first wedge block 31, thereby pushing the first wedge block 31 to slide along the first cavity 15. At this time, the first wedge block 31 compresses the second spring 34 and pushes the fixing rod 32 and the fixing block 33 to slide out of the second cavity 16. At this time, the fixing block 33 contacts the connecting tube 4 until the threaded bolt 38 can no longer be rotated downward, thereby completing the installation of the connecting tube 4 and solving the problem that the connecting tube 4 and the barbell bar are worn and difficult to replace during long-term use.

[0044] The remaining structures are the same as those of Example 1.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
