[0039] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0040] Example 1

[0041] like Figures 1-9 As shown in this embodiment, an adjustable dumbbell is provided, including a bar assembly 1 and two dumbbell bodies 2. The bar assembly 1 includes a handle 11, and both ends of the handle 11 are provided with connectors 13. Each of the two dumbbell bodies 2 includes multiple dumbbell plates 21, which are sequentially snapped together. The dumbbell body 2 has a U-shaped groove 23 that mates with the connectors 13. The connectors 13 and the dumbbell plates 21 are respectively provided with a first insertion hole 14 and a second insertion hole 22. When the connector 13 is placed inside the U-shaped groove 23, the second insertion hole 22 on the multiple dumbbell plates 21 is aligned with the first insertion hole 14.

[0042] Example 2

[0043] like Figures 3-8 As shown, based on Embodiment 1, in this embodiment, a baffle 12 is provided between the connecting body 13 and the handle 11, and the locking rod 3 is inserted into the interior of any one of the insertion holes 14 and the corresponding dumbbell plate 21 insertion hole 22, for locking the dumbbell plate 21 between the corresponding dumbbell plate 21 and the limiting baffle 12 onto the connecting body 13.

[0044] The interior of the connector 13 is provided with a groove 131 along the axial direction of the dumbbell rod assembly 1. The groove 131 intersects with the insertion hole 14. The interior of the groove 131 is provided with a plurality of elliptical locking beads 4. The two ends of the groove 131 are provided with springs 5 ​​for pressing the plurality of locking beads 4.

[0045] Under the elastic pressure of the two springs 5, the connection point of the two adjacent locking beads 4 is aligned with the corresponding insertion hole 14, and the two locking beads 4 at the very end are hollow. One end of the spring 5 is inserted into the interior of the locking bead 4 at the very end on the same side, which is beneficial for the assembly of the spring 5.

[0046] A lock groove 31 is provided on the side wall of the lock rod 3;

[0047] When the locking bar 3 is inserted into the first insertion hole 14 and the corresponding second insertion hole 22 on the dumbbell plate 21, the ends of the two corresponding locking beads 4 abut against the inside of the locking groove 31.

[0048] The insertion holes 14 and 22 form an acute angle with the horizontal plane, so that the end of the locking rod 3 can be inserted into the insertion holes 14 and 22 at an angle downwards. This makes the outer end of the locking rod 3 tilted upwards, which is beneficial for user operation.

[0049] The groove 131 on the connector 13 is open at both ends. One end of the groove 131 is blocked by the handle 11. The side wall of the connector 13 away from the limiting baffle 12 is provided with a cover plate 132 for blocking the other end of the groove 131.

[0050] The cover plate 132 is provided with multiple bolts, the threaded ends of which are engaged with the side wall of the connector 13 to fix the cover plate 132 to the connector 13.

[0051] The groove 131 on the connector 13 is open at both ends. One end of the groove 131 is blocked by the handle 11. That is, after the connector 13 is installed and fixed on the handle 11, the end face of the handle 11 naturally blocks one end of the groove 131 (the handle 11 and the connector 13 can be welded). The side wall of the connector 13 away from the limiting baffle 12 is provided with a cover plate 132 for blocking the other end of the groove 131. Multiple locking beads 4 and two springs 5 ​​are placed into the inside of the groove 131 in sequence. Then the cover plate 132 is fixed to the side wall of the connector 13 with bolts, thereby realizing the installation of multiple locking beads 4 and two springs 5 ​​into the inside of the groove 131.

[0052] Example 3

[0053] like Figure 1 and Figure 2 As shown, based on the above embodiment, this embodiment further includes a base 6 to allow for the orderly storage of dumbbell plates 21. The upper surface of the base 6 is recessed to form a placement groove 61. Two dumbbell bodies 2 are respectively placed at both ends inside the placement groove 61. The sidewalls of the placement groove 61 are provided with protruding ribs 62 for stabilizing the dumbbell plates 21. Figure 2 As shown, the dumbbell plates 21 are adapted to the shape of the placement slot 61. After two adjacent dumbbell plates 21 are snapped together, there are grooves on both sides that are adapted to the protruding ribs 62. When some dumbbell plates 21 are taken out of the placement slot 61, the protruding ribs 62 can abut against the remaining dumbbell plates 21 to prevent the remaining dumbbell plates 21 from tipping over.

[0054] like Figure 7 As shown, a locking block 24 is provided on the side of the lower end of the dumbbell plate 21 near the limiting baffle 12, and a slot 25 is provided on the side of the lower end of the dumbbell plate 21 away from the limiting baffle 12. When two dumbbell plates 21 are spliced ​​together, the locking block 24 on one dumbbell plate 21 is engaged in the slot 25 on the other dumbbell plate 21.

[0055] The process of adjusting the weight:

[0056] like Figure 1 As shown, dumbbell plates 21 are arranged in an orderly manner in the placement slot 61 of the base 6, and dumbbell bar assembly 1 is placed on the dumbbell plates 21. The two connecting bodies 13 are located in the U-shaped groove 23 on the same side. When all dumbbell plates 21 need to be used for counterweight, the locking rod 3 is inserted into the second insertion hole 22 of the outermost dumbbell plate 21. As the locking rod 3 continues to be inserted, the end of the locking rod 3 is inserted from the second insertion hole 22 into the first insertion hole 14. Then the end of the locking rod 3 will push the locking ball 4 open and pass through the hidden groove 131. After the locking rod 3 is fully inserted, the locking groove 31 on the locking rod 3 is exactly located in the hidden groove 131. Through the spring pressure of the spring 5, the locking ball 4 is pressed against the locking groove 31. At this time, the locking rod 3 can be used to connect all the dumbbell plates 21 to the inside of the connecting body 13.

[0057] When it is necessary to adjust the number of dumbbell plates 21 that can be lifted, simply insert the locking bar 3 into different sockets 22.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model. Any modifications or partial substitutions should be covered within the scope of the claims of this utility model.
