[0002] Dumbbells are a simple piece of equipment used for training to increase muscle strength. They are used for strength training and compound muscle exercises. There are many types of dumbbells, including simple dumbbells with a one-piece molded structure and dumbbells with adjustable weights.
[0003] With the increasing variety of training needs, dumbbells with adjustable weights have become popular among exercisers.
[0004] A dumbbell with adjustable counterweights typically consists of a metal grip bar, counterweights, and a stop plate.
[0005] Currently, existing dumbbells with adjustable counterweights generally require the limit plate to be rotated continuously and removed via a threaded drive before the counterweight can be removed. Then, the counterweight to be removed must be taken out, and finally, the limit plate must be rotated continuously to be installed onto the grip bar. This method increases the time and effort required to adjust and remove the counterweights on the dumbbell itself.
[0006] In addition, with existing adjustable dumbbells with counterweights, trainees may temporarily and casually place the dumbbells on the ground. Since the counterweights are disc-shaped, if the dumbbells are accidentally kicked, they will roll on the ground, causing the heavier dumbbells to collide with nearby objects or the trainee's legs.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0029] Reference Figure 1-5 A dumbbell with an adjustable counterweight includes a dumbbell body 1, which is composed of a grip bar 2 and a counterweight 5. The grip bar 2 is provided with a counterweight rod 3 and a hand guard plate 4. The counterweight 5 is provided with an adjusting pin 82. The counterweight 5 has an open inner groove 6 and an adjusting socket 51. The adjusting pin 82 is provided with a pull pin handle 8 and a spring 81.
[0030] The hand stop guard plate 4 is provided with a spring guard 41 and an anti-roll block 7. The anti-roll block 7 is provided with an anti-roll chamfer 71. The anti-roll block 7 and the anti-roll chamfer 71 are provided with a damping layer 72.
[0031] The pull pin handle 8 is provided with a finger groove 80, and the finger groove 80 is provided with an anti-slip layer 801. The anti-slip layer 801 is a frosted layer to improve the anti-slip performance of the finger when it is inserted into the finger groove 80.
[0032] The counterweight bar 3 is provided with a rounded corner 31 and an adjustment slot 32, and the inner groove 6 of the opening is provided with an arc-shaped chamfer 61. When a finger needs to be inserted into the finger clip slot 80, the setting of the arc-shaped chamfer 61 prevents the 90-degree opening corner of the inner groove 6 from blocking the finger insertion.
[0033] Some of the structures described in this patent are common structures for metal dumbbells and are existing technologies. Some of these existing structures are not drawn or labeled and need not be described in detail.
[0034] The adjustment slots 32 are arranged in two symmetrical groups, each group consisting of five horizontally arranged slots. The side section of the adjustment socket 51 is a rectangular opening that is horizontally connected to the counterweight 5, preventing the counterweight 5 inserted into the counterweight rod 3 from rotating, thereby achieving the positioning and locking of the adjustment pin 82 and the adjustment slots 32 in the later stage.
[0035] The finger slot 80 is an arc-shaped groove, which makes it easy to insert your finger and pull the pull pin handle 8, which is very convenient.
[0036] The adjusting pin 82 is slidably set with the counterweight 5 and engaged with the adjusting slot 32. The spring 81 is set between the inner groove 6 of the opening and the pull pin handle 8. The spring 81 is made of high-quality spring steel, with strong pull-back and durability, to ensure the stability of the adjusting pin 82 when it is engaged in the adjusting slot 32.
[0037] The inner groove 6 is a vertically open structure, and the pull pin handle 8 is not higher than the inner groove 6 to avoid foreign objects colliding with the pull pin handle 8 and causing instability of the adjusting pin 82.
[0038] The anti-roll blocks 7 are six arranged in a circle and set on the side end face of the handrail guard plate 4. The anti-roll blocks 7 are made of hard alloy steel, which is high in strength, pressure-resistant and durable, and has strong support.
[0039] Two anti-roll chamfers 71 are symmetrically arranged and are respectively located at the end corners of the anti-roll block 7. The damping layer 72 is evenly coated along the side end walls of the anti-roll block 7 and the anti-roll chamfers 71. The damping layer 72 is made of damping silicone coating material and has damping and anti-slip properties. Combined with the anti-roll chamfers 71 and the anti-roll block 7, the dumbbell body 1 can be stably placed on the ground to avoid rolling.
[0040] The handbrake guard plate 4 has a disc-shaped structure and consists of two symmetrical pieces. The handbrake guard plate 4 is made of No. 45 steel, which is high in strength and impact resistant.
[0041] The spring pad 41 is set on the inner wall surface of the hand stop guard plate 4. The spring pad 41 is made of high elastic silicone rubber material and has a high elastic cushioning effect.
[0042] The counterweight rod 3 has a rectangular strip structure, and the rounded corner 31 is set at the end corner of the counterweight rod 3, so that the counterweight block 5 can be quickly and smoothly inserted into the counterweight rod 3 through the adjustment socket 51.
[0043] Operating procedure: If it is necessary to adjust or remove the counterweights 5 at the very end of both sides, please refer to [the relevant documentation]. Figure 4 Taking the counterweight 5 at the right end as an example, insert your finger into the finger slot 80 and pull it outward, causing the pull pins 8 on both sides and the adjusting pin 82 to move outward simultaneously. When the adjusting pin 82 exits the adjusting slot 32, move the counterweight 5 to the right, and slide the current counterweight 5 along the counterweight rod 3 to the right. When the adjusting socket 51 on the counterweight 5 exits and disengages from the counterweight rod 3, the current counterweight 5 can be easily adjusted and removed. Similarly, the counterweight 5 on the left side can be easily adjusted and removed, avoiding the troublesome situation of adjusting and removing the counterweight 5 from the dumbbell body 1 by the threaded transmission and continuous rotation of the traditional limit plate. This effectively improves the convenience of adjusting and removing the counterweight 5 from the dumbbell body 1.
[0044] Moreover, when the dumbbell body 1 is briefly placed on the ground, the anti-roll block 7 is in direct contact with the ground through the damping layer 72, achieving a damping and anti-collision rolling effect, so that the dumbbell body 1 is placed stably on the ground, avoiding the dangerous situation where the dumbbell body 1 rolls on the ground due to the disc-shaped counterweight block 5 and directly collides with the adjacent objects or the legs of the trainees.
[0045] In addition, when the hand grips the handle bar 2, the skin of the hand will make elastic contact with the elastic pad 41, avoiding the discomfort of direct contact between the skin of the hand and the metal hand guard plate 4, and further improving the comfort of elastic contact between the skin of the hand and the hand guard plate 4.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
