[0027] The embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0028] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0029] As shown in Figure 1 , a multifunctional dumbbell is disclosed, comprising a dumbbell rod 1, two support plates 2 are movably installed on the dumbbell rod 1 at intervals.

[0030] Specifically, two limiting blocks 3 are provided on the dumbbell rod 1 at intervals, as shown in Figure 2 and Figure 3 . The part of the dumbbell rod 1 between the two limiting blocks 3 is a holding part for the hand to hold when exercising. The part of the dumbbell rod 1 outside the two limiting blocks 3 is a dumbbell piece mounting part for mounting the support plates 2 and the dumbbell pieces 7.

[0031] The bottom surface (the surface in contact with the ground) of the support plate 2 is a plane, or the middle part of the bottom surface of the support plate 2 is an upwardly arched arc, and the two ends are planes on the same horizontal line.

[0032] When a dumbbell with small weight is needed for exercise, the dumbbell pieces 7 can not be installed, the support plates 2 are sleeved on the dumbbell piece mounting part, and the support plates 2 are abutted with the limiting blocks 3 through the locking device 4.

[0033] Preferably, as shown in Figure 2 and Figure 4 , one end of the dumbbell piece mounting part in contact with the limiting block 3 is provided with a polygonal anti-rotation block 5. In this embodiment, the polygonal anti-rotation block 5 is a hexagonal anti-rotation block. A polygonal anti-rotation hole 6 is formed on the support plate 2, which is matched with the polygonal anti-rotation block 5. The polygonal anti-rotation block 5 and the polygonal anti-rotation hole 6 can further prevent the support plate 2 from rotating when the dumbbell is placed on the ground or when push-ups are performed.

[0034] The dumbbell piece mounting part is provided with a thread, and the locking device 4 is a locking nut connected with the dumbbell piece mounting part through the thread. As shown in Figure 6As shown, the locking device 4 has a threaded hole 10, and a locking screw 11 is threaded into the threaded hole 10. The locking screw 11 abuts against the dumbbell plate mounting part. The locking screw 11 ensures that the locking device 4 does not slip or disengage.

[0035] When heavy dumbbells are needed for exercise, several dumbbell plates 7 can be inserted between the support plate 2 and the locking device 4, depending on the specific needs. The dumbbell plates 7 are located between the locking device 4 and the support plate 2, so that the support plate 2 does not need to be removed when changing the dumbbell plates 7 to meet the needs of different people.

[0036] The dumbbell plates 7 are circular dumbbell plates with decreasing diameters. The diameter of the largest dumbbell plate 7 is smaller than the distance from the bottom surface of the support plate 2 to the dumbbell bar 1, to ensure that when the dumbbells are laid flat, the support plate 2 contacts the ground while the dumbbell plates 7 do not. A through hole adapted to the dumbbell plate mounting part is provided in the middle of the dumbbell plate 7, such as... Figure 5 As shown.

[0037] like Figure 3 As shown, the grip part has several annular grooves 8, and anti-slip sleeves 9 are installed in the annular grooves 8. This not only improves the user experience, but also prevents the dumbbells from slipping out of the hand due to sweaty palms from gripping the dumbbell bar for a long time, thus improving its safety performance.

[0038] The support plate 2 is covered with a protective sleeve. The protective sleeve is coated or injection molded onto the outside of the support plate 2, which can protect the support plate 2, prevent accidents, and greatly reduce the noise generated during use.

[0039] When exercising with dumbbells, first install the support plate 2 on the polygonal anti-rotation block 5. Then, as needed, place the required dumbbell plates 7 onto the dumbbell plate mounting part. Use the locking device 4 to ensure that the support plate 2 and the limiting block 3, and the dumbbell plates 7 and the support plate 2 are in close contact. Finally, use the locking screw 11 to fix the locking device 4 to the dumbbell plate mounting part. When doing push-ups or placing dumbbells, only the bottom surface of the support plate 2 needs to contact the ground.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
