Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a clip-on dumbbell. Background Art

[0002] Dumbbells are an auxiliary equipment for fitness exercises. They are named dumbbells because they do not make any sound when exercising. Dumbbells are frequently used in fitness and are loved by consumers. Frequent dumbbell exercises can enhance muscle strength in various parts of the body.

[0003] Dumbbells are similar to smaller versions of barbells. Dumbbell plates of varying weights are placed on both ends of a short iron rod. When using dumbbells, the number of dumbbell plates can be adjusted to increase or decrease the weight.

[0004] The existing application number is 202320490503.6, and the name is a utility model patent for an adjustable dumbbell, which includes a dumbbell rod and a plurality of dumbbell plates. The adjacent dumbbell plates on the same side are detachably connected and fixed accordingly by a fixing mechanism. The fixing mechanism includes a driving member and a sliding clamp. The driving member and the sliding clamp are both movably connected to the dumbbell plates to perform corresponding reciprocating motions. The sliding clamp is connected to an elastic driving member, which drives the sliding clamp to pop outward so that its clamping end is clamped and fixed with the clamping slot on the adjacent dumbbell plate. The driving member can drive the sliding clamp to move inward to disengage it from the clamping slot. However, the structure of this dumbbell is too complicated and difficult to produce and process. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a clip-on dumbbell, which solves the problem that the dumbbell has a complex structure and thus is difficult to produce and process.

[0007] Through the above technical solution, the locking mechanism includes a deformable sheet, a card block and a card slot. The deformable sheet is used to press the card block toward and engage the card slot. The deformable sheet is arranged in a curved shape as a whole. The locking mechanism has a simple structure and is convenient for production. The deformable sheet has toughness. The deformable sheet can press the card block toward the card slot to achieve locking, which is very simple and convenient to use.

[0014] Furthermore, a bending portion is provided on the end of the deformable sheet, the bending portion is concave to form a buckle portion, the edge of the second fixed plate is concave to form a top groove, and the top groove is connected to the positioning recess; when the clamping block and the clamping slot are clamped, the bending portion is engaged with the top recess.

[0015] Through the above technical solution, the top depression limits the bending part, further reducing the shaking between the dumbbell pieces when the dumbbell is in use, making the connection more stable, and the hand buckle provides more space for the hand to reach in, making it more convenient to use.

[0016] Furthermore, the first fixed plate is provided with a first enclosure, the second fixed plate is provided with a second enclosure, the dumbbell plate is provided with a first annular notch adapted to the first enclosure, and the dumbbell plate is provided with a second annular notch adapted to the second enclosure.
