With the above structural configuration, both the barbell bar 500 and the dumbbell bar 600 can be combined with the counterweight 100 by sliding and buckling each other, so as to improve the strength of the structural combination between each other. For weight training operations, part of the gravity can be dispersed in the Mutual sliding buckle assembly position.

The base 200 includes a cross bar 210 and a carrying plate 220 arranged on the cross bar 210 (near both ends); The moving plate 400 is provided with a locking part 410 that is movable and positioned with the limiting part 221. As shown in the tenth figure, the limiting part 221 in the embodiment is an example of a perforated structure, and the locking part 410 is an example of a convex structure. ; By means of the above-mentioned locking part 410 being able to be movable and stuck against the position of the limit part 221, the movable plate 400 is provided with the effect of being temporarily positioned on the carrier plate 220 when the movable plate 400 is in the close position and the separated position, so as to prevent the movable plate 400 from being placed on the carrier plate The phenomenon of self-displacement on 220. The fixed plate 300 is fixed on the carrying plate 220 and adjacent to the close position; the movable plate 400 is connected with one end of a vertical rod 420 passing through the carrying plate 220 and the cross bar 210, so that the end of the vertical rod 420 limits the movable plate 400 is completely disengaged from the cross bar 210 , and the pulley block 240 is slid in the cross bar 210 to slide toward the approaching position and the separation position and allow the longitudinal bar 420 to move along its axial direction.

In addition, the crossbar 210 of the base 200 is provided with a hook 230 for placing the barbell 500 , which can be used to store the barbell 500 when switching to a dumbbell mode for weight training. Two handles 430 extend outward from opposite sides of the movable disk 400 , which can be grasped at the position of the handle 430 to move the movable disk 400 .

The following further describes the operation conversion between the barbell and the dumbbell in the barbell and dumbbell device 1, and please refer to the fourth to ninth diagrams. First release the locking mechanism 501 of the barbell 500 located on the split groove 130 of the counterweight 100, and pull it back to the first connecting piece 510 and the second connecting piece 520 of the barbell 500, and then move the barbell 500 from the base 200 Pull upwards so that the first connecting piece 510 and the second connecting piece 520 of the barbell 500 are disengaged from the slider assembly of the counterweight 100 on the movable plate 400 , and the detached barbell 500 can be placed on the hook 230 . Lift up the handles 430 on both sides of the movable plate 400 together with the counterweight 100 carried by it, so that the counterweight 100 on the movable plate 400 and the counterweight 100 on the fixed plate 300 can release the sliding buckle assembly After forming a separated appearance (the lifting action of the movable plate 400 is limited by the lower end of the longitudinal bar 420 to the bottom position of the cross bar 210), the movable plate 400 can be pushed to the separated position together with the counterweight 100 carried by it, or After the lifting action, it is directly moved to the top of the separation position and then lowered to the separation position for positioning. Complete the aforementioned After the position of the movable plate 400 is adjusted, the dumbbell bar 600 located between the fixed plate 300 and the movable plate 400 and the position above the carrying plate 220 can be grabbed and assembled downwards, so that the first connecting piece 610 and the second connecting piece 610 at both ends of the dumbbell bar 600 The two connecting pieces 620 are slidingly assembled with the counterweight 100 of the fixed tray 300 and the counterweight 100 of the movable tray 400 respectively. Finally, the locking mechanism 601 of the dumbbell bar 600 is manipulated to move the selected number of counterweights 100 to a locked state, so that the dumbbell mode can be provided for weight training. Switching from dumbbell mode to barbell mode can be achieved by roughly operating in reverse to the above description.

Please refer to the first, second and eleventh figures, the bottom ends of the first part 140 and the second part 150 are respectively provided with end grooves 160, and the end grooves 160 of the first part 140 and the second part 150 Not communicated with, nor communicated with the slit 130; both sides of the movable plate 400 are provided with baffles 440 which are stuck in the end groove 160 of the counterweight 100 to limit the counterweight 100 comes off from movable disc 400 both sides.

In the process of moving the movable disk 400 between the close position and the separated position, through the sliding operation of the pulley block 240 in the cross bar 210, especially when the movable disk 400 carries a certain number of counterweights 100, the movable disk can be moved smoothly. 400 is displaced relative to the cross bar 210, as shown in the seventh and twelfth figures.

It is worth mentioning that the known technology Taiwan New Patent No. M613036, No. M594976, and the U.S. invention patent US11207557B2 have dumbbells and barbells, and when performing operation conversion between the barbells and dumbbells, due to the single dovetail and single Corresponding joints between the dovetail slots require turning the support platform (plate) 180 degrees to complete the assembly of the counterweight and the grip bar, which is troublesome in use. And this creation is set in the opposite direction through the first draw-in slot 111 of the counterweight 100 and the second draw-in block 121, the first draw-in block 112 is set in the opposite direction with the second draw-in slot 122, and the first connecting piece 510 ( The first connection groove 511, the first connection block 512 configuration) and the second connection piece 520 (the second connection block 521, the second connection groove 522 configuration), and the first connection piece 610 of the dumbbell bar (the first connection groove 611, The first connecting block 612 configuration) and the second connecting piece 620 (configuration of the second connecting block 621 and the second connecting groove 622 ), etc., it is possible to switch between the barbell mode and the dumbbell mode without changing the direction of the counterweight 100 .
