Description

Technical Field

[0001] The utility model relates to the technical field of dumbbells, in particular to a dumbbell with adjustable weight. Background Art

[0002] Dumbbells are one of the commonly used fitness equipment for modern people at home. Their function is that people can exercise arm strength by lifting dumbbells, so as to achieve the effects of muscle building and bodybuilding. At present, dumbbells generally have a weight adjustment function. When people keep doing fitness exercises, the weight of the dumbbells they need to lift will gradually increase;

[0003] For existing dumbbells, users often need many dumbbell plate counterweights of different weights. Before and after adding or reducing the counterweights, they need to disassemble and install by rotating nuts, so it is rather cumbersome to increase or decrease the dumbbell plate counterweights. For this reason, we have proposed a dumbbell with adjustable weight. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a dumbbell with adjustable weight, which solves the problems raised in the above background art.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a dumbbell with adjustable weight, including a grip rod assembly. Multiple groups of first counterweight assemblies and second counterweight assemblies are sequentially installed at both ends of the grip rod assembly, and the structures of each group of first counterweight assemblies and each group of second counterweight assemblies are the same. A base assembly is commonly connected to the bottoms of the two groups of second counterweight assemblies;

[0006] The grip rod assembly includes a grip rod. Connecting seats are connected to both ends of the grip rod. Multiple groups of rotating rods are rotatably connected at equal intervals inside each connecting seat. The bottom end of each group of rotating rods is connected to a connecting plate, and two groups of convex blocks are symmetrically connected to the outer surface of the bottom of each group of connecting plates. The top end of each group of rotating rods is connected to a knob;

[0007] The first counterweight assembly includes a counterweight block. A lower column groove, an upper column groove and two groups of notch grooves are opened at the center of the bottom of the counterweight block. The upper column groove and the two groups of notch grooves are located above the lower column groove. The two groups of notch grooves are located on both sides of the upper column groove. The size of the top of the connecting plate is adapted to the upper column groove, and the size of each group of convex blocks is adapted to each group of notch grooves.

[0008] As a further technical solution of the utility model, multiple groups of guiding grooves are equally spaced on the side surface of each connecting seat. The positions of the multiple groups of guiding grooves correspond to the positions of the multiple groups of rotating rods. The number of the multiple groups of rotating rods corresponds to the number of the multiple groups of first counterweight assemblies and the two groups of second counterweight assemblies.

[0009] As a further technical solution of the present utility model, guide bars are connected to the inner sides of the counterweight blocks. The counterweight blocks are located outside the connecting seat, and each group of guide bars is located inside each group of guide grooves.

[0010] As a further technical solution of the present utility model, the base assembly includes two groups of bases. A connecting rod is commonly connected to the sides of the two groups of bases, and multiple placement grooves are formed at the top of each group of bases.

[0011] As a further technical solution of the present utility model, the size of the bottom of each placement groove is adapted to the sizes of the multiple first counterweight assemblies and the two second counterweight assemblies. The two second counterweight assemblies are located at both ends of the two groups of bases and are fixedly connected.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. For the weight-adjustable dumbbell of the present utility model, by selecting multiple groups of first counterweight assemblies and two groups of second counterweight assemblies according to the weight requirements of the user, the adjustment of different weights of the dumbbell is completed. In addition, the connecting plate and the two convex blocks rotate in the lower column groove, and through extrusion, the first counterweight assembly, the second counterweight assembly and the grip rod assembly can be quickly disassembled and assembled, and the increase and decrease of the counterweight blocks are relatively simple.

[0014] 2. For the weight-adjustable dumbbell of the present utility model, the two second counterweight assemblies are fixedly connected to both ends of the two groups of bases. When not in use, the two groups of bases are placed on the ground, so that the two second counterweight assemblies remain in a vertical state. Moreover, through the placement grooves, the first counterweight assemblies can be placed when not in use, so that the first counterweight assemblies remain in a vertical state. Therefore, the first counterweight assemblies and the second counterweight assemblies are prevented from being scattered when not in use, which is convenient for the user to add and reduce the first counterweight assemblies and the second counterweight assemblies according to the weight requirements.
