[0023] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0024] The embodiments of the present utility model disclose a barbell for strength training.

[0025] The present utility model provides as Figures 1-4A barbell for strength training as shown includes a bottom plate 1 and multiple arc-shaped limiting plates 2. Two barbell racks 3 are fixedly arranged on the top of the bottom plate 1. Rectangular limiting grooves 4 are formed on the side walls of the two barbell racks 3. A barbell rod 5 is inserted between the two rectangular limiting grooves 4. Multiple barbell plates 6 are threadedly sleeved on the rod walls at both ends of the barbell rod 5. Multiple telescopic rods 7 are fixedly arranged on the top of the bottom plate 1. A U-shaped plate 8 is fixedly arranged at the top of each telescopic rod 7. Each arc-shaped limiting plate 2 is arranged inside the corresponding U-shaped plate 8. The inner wall of each arc-shaped limiting plate 2 is in contact with the barbell rod 5. A fixing mechanism is arranged on the side wall of the barbell rod 5, and multiple barbell plates 6 are all matched with the fixing mechanism. By using the two telescopic rods 7 and multiple arc-shaped limiting plates 2 arranged, it is ensured that the user can perform a vertical stretching movement on the barbell, preventing the barbell from shifting during the lifting process, resulting in a poor muscle training effect. In severe cases, it may cause muscle soreness and deformation.

[0026] In order to fix the barbell plates 6 and also facilitate the user to increase or decrease the number of barbell plates 6, as Figures 1-2 shown, the fixing mechanism includes two fixing plates 9 and two castellated nuts 10. Each fixing plate 9 is fixedly sleeved on the outer wall of the barbell rod 5. Each fixing plate 9 is attached to one side of the corresponding barbell plate 6. External threads are formed on the outer walls at both ends of the barbell rod 5. Each castellated nut 10 is threadedly sleeved on the outer wall of the barbell rod 5. Each castellated nut 10 is attached to the other side of the corresponding barbell plate 6. By using the arranged fixing mechanism, the barbell plates 6 can be fixed, and it is also convenient for the user to increase or decrease the number of barbell plates 6.

[0027] And in order to position two adjacent arc-shaped limiting plates 2 and ensure that two adjacent arc-shaped limiting plates 2 can stably fit on the outer wall of the barbell rod 5, as Figures 1-3 shown, two mounting plates 11 are fixedly arranged on the side wall of each arc-shaped limiting plate 2. Two sliding rods 12 are fixedly arranged on the inner wall of each U-shaped plate 8. Each sliding rod 12 is movably sleeved inside the corresponding lower mounting plate 11. Each two upper and adjacent mounting plates 11 are threadedly connected by bolts 13. By using the arranged sliding rods 12 and bolts 13, two adjacent arc-shaped limiting plates 2 can be positioned, ensuring that two adjacent arc-shaped limiting plates 2 can stably fit on the outer wall of the barbell rod 5.

[0028] And in order to buffer the placement of the barbell rod 5 and prevent the barbell rod 5 from being damaged by knocking, as Figures 1-2 and Figure 4 shown, a buffer pad 14 is fixedly arranged on the inner wall of each rectangular limiting groove 4. The barbell rod 5 is arranged on the top of the two buffer pads 14. By using the arranged buffer pads 14, the placement of the barbell rod 5 can be buffered, preventing the barbell rod 5 from being damaged by knocking.

[0029] In order to improve the anti-slip effect of the barbell rod 5 and prevent the barbell rod 5 from slipping, as Figures 1-2 shown, an anti-slip sleeve 15 is fixedly arranged on the outer wall of the barbell rod 5. The anti-slip sleeve 15 is a silica gel sleeve. By using the provided anti-slip sleeve 15, the anti-slip effect of the barbell rod 5 can be improved, and the barbell rod 5 can be prevented from slipping.

[0030] Finally, in order to ensure that the buffer pad 14 can have a high buffering effect, as Figures 1-2 shown, each buffer pad 14 is a rubber pad, thereby ensuring that the buffer pad 14 can have a high buffering effect.

[0031] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
