[0037] The movable supporting component is arranged on the movable positioning ring 19 to support the dumbbell plate 2.

[0038] In the embodiment of the utility model, when in use, the dumbbell piece 2 is installed on the dumbbell bar 1 and abutted against the limiting ring 3, and then fixed. When it is subsequently placed, the movable support assembly on the movable positioning ring 19 is opened, so as to abut against the ground to form a support and prevent movement;

[0039] By fixing the counterweight 7 at the bottom of the movable positioning ring 19, the upper and lower ends of the movable positioning ring 19 remain unchanged, thereby facilitating pressing and further facilitating supporting work.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, the surface of the dumbbell bar 1 is also provided with a rotating structure, and the rotating structure includes a movable groove 14, a supporting frame 4, a ball 5 and an anti-drop unit. The movable groove 14 is opened in the middle of the dumbbell bar 1, and the supporting frame 4 is slidably installed on the surface of the movable groove 14. The surface of the supporting frame 4 is fixedly installed with an anti-slip sleeve 10. The ball 5 is movably installed in a circular array at the bottom of the supporting frame 4 and movably abuts against the surface of the dumbbell bar 1, and the anti-drop unit is arranged on the surface of the anti-slip sleeve 10.

[0041] In the embodiment of the utility model, when in use, the hand holds the anti-slip cover 10 and then rotates the dumbbell as a whole. Due to the presence of the support frame 4 and the ball 5, the hand-held part does not rotate during rotation exercise, and the dumbbell bar 1 and the dumbbell plate 2 rotate relatively independently, thereby reducing the damage to the hand and reducing the damage caused by exercise;

[0042] By setting up an anti-drop unit, it is possible to prevent the hands from breaking apart and causing the dumbbells to fly out and hit other people or things.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, as a preferred embodiment of the utility model, the movable supporting assembly includes a receiving slot 6, a clamping slot 12, a tension spring 9 and a limit clamp 18. The receiving slot 6 starts on the left and right sides of a movable positioning ring 19. The interior of the receiving slot 6 is movably hinged with a positioning rod 8. The clamping slot 12 is opened at the bottom of the inner side of the receiving slot 6. The tension spring 9 is fixedly installed on the left and right sides of the bottom of the clamping slot 12 and is fixedly connected to the surface of the counterweight 7.

A spring 13 is fixedly installed at the bottom of the limit clamp 18, and the bottom of the spring 13 is fixedly connected to the lifting slot 11.

[0044] In the embodiment of the utility model, when in use, when the dumbbell piece 2 is placed on the ground, the movable positioning ring 19, due to the presence of the counterweight 7, makes its limit clamp 18 always have a top no matter what angle the dumbbell piece 2 is placed, and then presses the bulge in the middle of the limit clamp 18, thereby overcoming the elasticity of the spring 13 in the lifting groove 11, so that the two ends pop out from the clamping groove 12 at the lower end of the surface of the positioning rod 8, and then under the action of the tension spring 9, the positioning rod 8 quickly leaves the storage groove 6 when it loses its constraint, and rotates to both sides to open, and then contacts the ground;

[0045] By providing a movable support component, a simple triangular support structure is formed with the ground during use, so that the dumbbell plate 2 will not move when placed.

[0046] like Figure 4 and Figure 5 As shown, as a preferred embodiment of the utility model, the limit card 18 is arranged in a mountain shape as a whole, and the left and right sides of the limit card 18 protrude from the surface of the movable positioning ring 19, and are movably inserted in the slot 12, and the middle of the limit card 18 protrudes from the surface of the movable positioning ring 19 for easy pressing.

[0047] In the embodiment of the utility model, when in use, the middle protrusion of the limit clamp 18 is pressed so that the protrusions on both sides are separated from the clamping slot 12;

[0048] The limiting clamp 18 is configured as a mountain shape as a whole, so that separation and clamping are convenient.

[0049] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, the falling unit includes a ring 15 and a connecting belt 16, the ring 15 array is installed on the surface of the anti-slip sleeve 10, the connecting belt 16 is fixedly installed on the surface of the movable groove 14, and the bottom array of the connecting belt 16 is symmetrically and staggeredly installed with anti-fall adhesive tapes 17.

[0050] In the embodiment of the utility model, when in use, the connecting belt 16 fixed on the surface of the anti-slip sleeve is placed on the hand, and then the anti-drop adhesive tapes 17 are alternately adhered to each other to surround the wrist;

[0051] By setting up a drop unit, it is possible to avoid the dumbbells flying out due to hand slipping during rotation exercises.

[0052] like Figure 1 As shown, as a preferred embodiment of the present utility model, the facing surfaces of the anti-drop adhesive tape 17 are provided with Velcro.

[0053] In the embodiment of the utility model, when in use, Velcro is provided on the facing surfaces of the anti-drop adhesive tape 17, thereby facilitating the sticking and separation.

[0054] like Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present utility model, the width value of the positioning rod 8 is equal to the width value of the receiving groove 6, and the curvature value of the positioning rod 8 is equal to the curvature value of the receiving groove 6.

[0056] The above embodiment of the utility model provides a rotatable dumbbell. When using it, the user places the connecting belt 16 fixed on the surface of the anti-slip sleeve on the hand, and then sticks the anti-drop adhesive tapes 17 to each other in an interlaced manner, so as to surround the wrist, thereby preventing the dumbbell from flying out due to hand slipping during rotation exercise;

[0057] When rotating, the hand holds the anti-slip cover 10 and then rotates the dumbbell as a whole. Due to the presence of the support frame 4 and the ball 5, the hand-held part does not rotate during the rotation exercise, and the dumbbell bar 1 and the dumbbell plate 2 rotate relatively independently, thereby reducing the damage to the hand and reducing the damage caused by the exercise;

[0058] When it needs to be placed on the ground, the dumbbell plate 2 is placed on the ground, and then the movable positioning ring 19, due to the presence of the counterweight 7, ensures that its limit card 18 always has a top no matter at what angle the dumbbell plate 2 is placed, and then presses the protrusion in the middle of the limit card 18, thereby overcoming the elasticity of the spring 13 in the lifting groove 11, so that the two ends pop out from the groove 12 at the lower end of the surface of the positioning rod 8, and then under the action of the tension spring 9, the positioning rod 8 quickly leaves the storage groove 6 when it loses its constraint, and rotates to both sides to open, and then contacts the ground, thereby forming a simple triangular support structure with the ground, so that the dumbbell plate 2 will not move when it is placed.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
