Description

Technical Field

[0001] This utility model relates to the field of dumbbell technology, and more specifically to an adjustable weight anti-slip dumbbell. Background Technology

[0002] Dumbbells, as the most basic and historically significant resistance training equipment, have a simple core function (using gravity for strength training), but their materials, structure, and manufacturing processes have continuously evolved over time. Early Forms (Original Materials): The earliest dumbbells can be traced back to ancient Greece and Rome. They were mostly fixed weights made of stone or metal (such as lead), with handles for easy gripping, and the craftsmanship was rough. The Cast Iron Era (Standardization and Mass Production): After the Industrial Revolution, the maturity of casting technology (especially sand casting) enabled dumbbells to enter a stage of large-scale standardized production. Pig iron became the mainstream material, and fixed-weight dumbbells of different weights (such as pounds / kilograms) could be manufactured using molds. The surface was often painted to prevent rust. This was the prototype of the modern dumbbell. The Birth of Adjustable Dumbbells (Structural Innovation): To solve the problems of large space occupation and high cost of fixed dumbbells, adjustable dumbbells appeared in the early 20th century. Early designs often used hexagonal nuts or clamps to lock the counterweight plates (usually cast iron discs) at both ends of the fixed bar. This greatly improved the flexibility and economy of dumbbell use.

[0003] The existing dumbbells have some shortcomings in use, as follows: The weight of the existing dumbbells cannot be adjusted according to the user's actual training needs, so users need dumbbells of different weights, which is inconvenient for users. In addition, the existing dumbbells are held by the user, so the user's hand may slip and it is not easy to hold them. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable weight anti-slip dumbbell to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an adjustable weight anti-slip dumbbell, including a positioning rod assembly, counterweight components installed on both sides of the positioning rod assembly, an anti-slip component installed on the outer side of the positioning rod assembly, the positioning rod assembly including a positioning rod body, mounting positioning blocks fixedly connected to both sides of the positioning rod body, a first mounting positioning groove is formed on the side of the mounting positioning block away from the positioning rod body, and a first mounting sliding groove is formed on the front of the first mounting positioning groove.

[0006] Furthermore, the counterweight assembly includes a counterweight block body, a second mounting positioning groove is provided on one side of the counterweight block body, a second mounting sliding groove is provided on the front of the second mounting positioning groove, a first mounting positioning block is fixedly connected to the other side of the counterweight block body, and a second mounting positioning block is fixedly connected to the other side of the first mounting positioning block.
