Problems solved by technology

[0003] Traditional dumbbells are divided into various models according to different weights, and their weights cannot be adjusted. With the increase of practice time, users must purchase multiple sets of dumbbells of different weights in order to meet the needs of increased strength, which undoubtedly increases the cost; , a dumbbell whose weight can be adjusted has appeared. Its structure is to arrange multiple dumbbell pieces at both ends of the dumbbell bar, and fix them with bolts and nuts. Users can disassemble the dumbbell pieces according to their needs. The operation is troublesome and requires tools such as wrenches , not easy to use
[0004] In the prior art, the patent application number 201620757677.4 discloses a weight-adjustable dumbbell, which includes a plurality of dumbbell pieces, the two ends are used to accommodate the bases of the vertically placed dumbbell pieces, and there is a grip part in the middle, which can rotate at different angles Dumbbell pieces of different weights are automatically locked at both ends, and the remaining dumbbell pieces are left on the dumbbell bar in the base; the dumbbell bar includes a mandrel with a grip in the middle, and is fixed to the weight at the end of the mandrel. The adjustment dials are set at both ends of the mandrel, which match the shape of each dumbbell plate respectively, and rotate together with the weight adjustment dial, so that the dumbbell plates of the corresponding weight are stuck on the outer edge, so that the modified dumbbell plates are locked to the multiple weights on it. Cam sheet; but in this technology, since one edge of each dumbbell sheet is provided with a deep groove, the position of the center of gravity of each dumbbell sheet is far away from the central axis of the dumbbell sheet; when operating its dumbbell , due to the different directions in which the dumbbells are lifted, it will cause the dumbbell bar to be subjected to rotational force. Arm strain; also because the positioning button of its dumbbell is located in a place that is easy to misuse, when the positioning button is misoperated, the dumbbell piece in the dumbbell bar will fall off and hurt people, which is a great safety hazard

Abstract

The invention relates to a dumbbell support device with good weight-adjusting convenience for use in dumbbells and belongs to the technical field of fitness products. The dumbbell support device comprises a dumbbell support device body; a base is arranged in the dumbbell support device body; two support blocks and six guide sleeves are mounted on the base; a controller is arranged between each guide sleeve and two support blocks; a second spring is arranged in each guide sleeve and is connected with the corresponding controller connected. The dumbbell weight can be adjusted just by pulling upthe different controllers with no need for external tools, so that good convenience of use is provided. The problem is solved that when a dumbbell is lifted in different directions, a dumbbell bar maybear rotational force. The dumbbell support device prevents misopeartion and guarantees safety of use.

Description

technical field [0001] The invention relates to a dumbbell supporting device in a dumbbell which is convenient for weight adjustment, and belongs to the technical field of fitness products. Background technique [0002] Dumbbell is an auxiliary equipment for weightlifting and fitness exercises.
