Description

Technical Field

[0001] The utility model belongs to the technical field of dumbbell counterweights, and particularly relates to an additional counterweight block for a fixed-weight dumbbell. Background Art

[0002] Dumbbells are important training equipment for sports such as weightlifting and fitness, and are used for trainees to perform anti-resistance active exercises. Dumbbells are divided into fixed-weight dumbbells and detachable dumbbells according to whether the counterweight can be increased or decreased. Detachable dumbbells are commonly used in home fitness, and fixed-weight dumbbells with increasing weights are commonly used in commercial gyms to meet the needs of trainees to quickly change the training weight, and a set of dumbbells can be used by multiple trainees. However, fixed-weight dumbbells are more expensive than detachable dumbbells, and there is a lack of gradient between weights, especially between heavier dumbbells. Moreover, if the heaviest dumbbell in a set of fixed-weight dumbbells is difficult to meet the training weight requirements of trainees, the high price makes it difficult to solve the problem by adding one or several pairs of heavier dumbbells.

[0003] Therefore, those skilled in the art provide an additional counterweight for a fixed-weight dumbbell to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a fast, adjustable and safe additional counterweight block for a fixed-weight dumbbell.

[0005] The utility model solves its technical problems through the following technical solutions:

[0006] An additional counterweight block for a fixed-weight dumbbell, characterized in that: it includes a counterweight block unit, a strap and a fixing buckle. The counterweight block unit includes a number of counterweight blocks with the same weight and size. Through holes are provided on each of the counterweight blocks of the counterweight block unit. The number of counterweight blocks pass through the strap through the through holes and are evenly distributed on the strap. A fixing buckle is provided at the end of the strap, and the strap is tightened and fixed through the fixing buckle.

[0007] Moreover, a rubber anti-slip pad is adhesively bonded to the inner wall surface of the counterweight block, and a number of anti-slip lines are provided on the rubber anti-slip pad.

[0008] Moreover, the fixing buckle includes a buckle ring one and a buckle ring two, and the free end of the strap passes through the buckle ring one and the buckle ring two in sequence to achieve tightening and fixing.

[0009] Moreover, the strap is made of canvas material, and the counterweight block is made of stainless steel material.

[0010] The advantages and beneficial effects of the utility model are:

[0011] 1. The present utility model is applied to additional weights for fixed-weight dumbbells, which can achieve reliable fixation of the additional weights and reduce the cost of increasing the weight gradient for a set of fixed-weight dumbbells.

[0012] 2. The present utility model can increase the number of weight blocks according to requirements to achieve fine adjustment of additional weights, assisting the trainer to safely and steadily increase the training intensity.

[0013] 3. The present utility model can achieve rapid installation, addition, and removal of additional weights, shortening the adjustment and installation time and ensuring an appropriate rest length between training sets.

[0014] 4. The present utility model is compatible with various forms of fixed-weight dumbbells.

[0015] 5. The present utility model is safe and reliable, avoiding the risk of weight slippage during training and ensuring training safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] DESCRIPTION OF THE REFERENCE NUMERALS

[0021] 1 - weight block unit, 101 - weight block, 102 - rubber anti-slip pad, 2 - strap, 3 - fixing buckle, 301 - buckle one, 302 - buckle two, 4 - fixed-weight dumbbell. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further details the present utility model through specific embodiments. The following embodiments are only descriptive and not restrictive, and cannot be used to limit the protection scope of the present utility model.

[0023] Referring to Figures 1-4 , an embodiment provided by the present utility model: An additional weight block for a fixed-weight dumbbell includes a weight block unit 1, a strap 2, and a fixing buckle 3. The weight block unit 1 includes a weight block 101 and a rubber anti-slip pad 102. The weight block 101 and the rubber anti-slip pad 102 are adhesively bonded. The weight block 101 is designed with a through hole so that the strap 2 can pass through the weight block. The weight block 101 is made of stainless steel, and each has a mass of 0.25 kg. In this embodiment, the additional weight block for the fixed-weight dumbbell is as Figure 2As shown in the figure, around the dumbbell counterweight part, the 102 rubber anti-slip pads are in contact with the dumbbell counterweight part to prevent the additional counterweight blocks from slipping. The fixing buckle 3 is used to tighten the strap, and the fixing buckle 3 includes a buckle ring 1 (301) and a buckle ring 2 (302). For a dumbbell 4 with a fixed weight, generally two sets of additional counterweight blocks are used, which are respectively fixed on the counterweight parts on both sides of the dumbbell. Different additional counterweight requirements can be achieved by adjusting the number of counterweight blocks, and the counterweight blocks can be increased or decreased when the fixing buckle 3 is opened.

[0024] In this embodiment, for the additional counterweight operation of the dumbbell, first, the anti-slip counterweight blocks 1 that meet the additional weight quantity are passed through the through holes one by one with the strap 2.

[0025] Further, the strap together with the anti-slip counterweight blocks is wound around the dumbbell counterweight part. One end of the strap passes through the buckle ring 2 (302), and after being folded back, it passes through the buckle ring 1 (301).

[0026] Further, adjust the positions of the anti-slip counterweight blocks to make the counterweight blocks evenly distributed.

[0027] Finally, tighten the strap to complete the additional counterweight configuration.

[0028] Repeat the above steps to complete the additional counterweight operation for the other side of the dumbbell.

[0029] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art can understand that: within the spirit and scope of the present invention and the appended claims, various substitutions, changes, and modifications are possible. Therefore, the scope of the present invention is not limited to the content disclosed in the embodiments and drawings.
