Embodiment 1

[0020] Such as Figure 1 to Figure 3 As shown, a dumbbell piece includes a disc-shaped box body, and the box body is formed by connecting a first half box body 1 and a second half box body 2 . Filling is housed in the box body. The filling is a mixture of basalt and Portland cement. A shaft sleeve 4 is arranged in the center of the box body, and flanges 9 are respectively arranged at both ends of the shaft sleeve 4 . The flange 9 can limit the position of the first half box body 1 and the second half box body 2, so that the two are buckled together to form a complete box body. The flanging 9 at both ends of the shaft sleeve 4 can be formed by stamping. Both ends of the shaft sleeve 9 are provided with buffer sheets 5, and the buffer sheets 5 are made of rubber. The buffer sheet 5 can act as a buffer between two adjacent dumbbell sheets.

[0021] A protective cover 6 is sheathed on the circumferential direction of the box body, and the protective cover 6 is made of rubber....

Abstract

The invention discloses a dumbbell piece comprising a disc-shaped box body. A filler is arranged in the box body, and a shaft sleeve is arranged in the center of the box body; a protective sleeve is arranged in the circumferential direction of the box body, a plurality of ribs are arranged on the inner side of the protective sleeve, a plurality of air chambers are formed between the protective sleeve and the box body, and a plurality of exhaust holes are formed in the circumferential direction of the protective sleeve. And a plurality of contact buffer devices are arranged on the outer ring surface of the protective sleeve. According to the invention, when the dumbbell piece fall onto the ground, a good buffering effect is formed between the dumbbell piece and the ground, the impact forcebetween the dumbbell piece and the ground is greatly reduced, the dumbbell piece is well protected, and the ground is prevented from being smashed.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to a dumbbell plate. Background technique [0002] Dumbbells are a commonly used fitness equipment. The weight of existing dumbbells is regulated by increasing or reducing the quantity of dumbbell pieces. Existing dumbbells are usually a disk-shaped metal body, which itself has a certain weight. If the dumbbells are accidentally dropped to the ground during use, usually the outer edge of the dumbbells contacts and collides with the ground. The impact force generated by the dumbbell plate and the ground will cause damage to the dumbbell plate and easily smash the ground. [0003] For example: Chinese Patent Publication No. CN103157223A, the name of the invention is a kind of dumbbell, including a grip bar and a dumbbell piece. The grip bar is provided with threaded holes connected at both ends. At both ends of the grip bar, the other ends of the two screw rods are fixed ...
