Description

Technical Field

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

[0002] Adjustable dumbbells are a type of fitness equipment.

[0003] It has the following features:

[0004] Weight adjustability: By changing the number or combination of dumbbell plates, the overall weight of the dumbbell can be easily adjusted to suit different training intensities and stages.

[0005] Versatility: It can perform a variety of strength training movements, such as curls, lateral raises, bench presses, etc., to exercise muscles in different parts of the body.

[0006] Save space: Compared with multiple fixed-weight dumbbells, adjustable dumbbells save more storage space.

[0007] For example, those who are just starting out with weak strength can start with a lighter weight and gradually increase the weight as their strength improves. Common adjustable dumbbells include those that adjust the weight with a knob and those that require manual adjustment of the dumbbell plates. These offer a more flexible and convenient way for fitness enthusiasts to train.

[0008] The weight plates on dumbbells are generally round. The round shape may cause multiple dumbbells to roll and collide with each other when placed, which can easily injure the feet. They require a larger space to store and are not placed neatly and orderly. Utility Model Content

[0010] To achieve the above object, an adjustable dumbbell is provided, comprising a handle, wherein a first limiting plate is fixedly mounted on one end of the handle, and a second limiting plate is fixedly mounted on the other end of the handle, and a first counterweight assembly is mounted on a side of the second limiting plate away from the handle, and a second counterweight assembly is mounted on a side of the first limiting plate away from the handle;

[0011] The first counterweight assembly includes a screw rod fixedly connected to the second limiting piece, and a counterweight plate is installed on the screw rod. At the same time, the screw rod and the locking cylinder are adapted in size, and the locking cylinder is screwed to the outside of the screw rod.

[0012] Preferably, the first counterweight assembly and the second counterweight assembly have the same composition structure, and the first counterweight assembly and the second counterweight assembly are symmetrical structures with respect to the handle.

[0013] Preferably, a gripping portion is provided in the middle of the handle, and the diameter of the gripping portion is smaller than the diameter of the handle, and connecting portions are provided between both sides of the gripping portion and the handle.

[0014] Preferably, the counterweight discs are evenly arranged in multiple groups on the screw rod, and the counterweight discs are triangular structures made of metal material, and the three ends of the counterweight discs are all arranged in an arc shape.

[0015] Preferably, a circular mounting hole is provided in the middle of the counterweight plate, and the inner diameter of the mounting hole is larger than the diameter of the screw.

[0016] Preferably, multiple sets of counterweight plates are fixed on the screw rod through a locking cylinder, and a force plate is fixedly set at the end of the locking cylinder. At the same time, the force plate is circular, and multiple sets of arc-shaped force grooves are equidistantly set on the outer surface of the force plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: a first counterweight assembly and a second counterweight assembly are arranged on the two parts of the handle, and multiple groups of triangular counterweight plates are evenly arranged on the first counterweight assembly and the second counterweight assembly. The counterweight plates are arranged in a triangular shape and can be stably supported on the ground. A large number of dumbbells can be evenly distributed at the target position without rolling or hitting the user's feet when rolling. They are arranged neatly and orderly, and a large number of dumbbells can be stacked, reducing the storage space of a large number of dumbbells. BRIEF DESCRIPTION OF THE DRAWINGS
