Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to plate-type dumbbells. Background Technology

[0002] Dumbbells are a simple piece of equipment used for training to increase muscle strength. Their main material is cast iron; their purpose is for muscle strength training and compound muscle movement training. Patients with low muscle strength due to paralysis, pain, or prolonged inactivity can use dumbbells to perform active resistance exercises, thus training muscle strength. Dumbbells can train single muscles; as the weight is increased, the coordination of multiple muscles is required, making it suitable for compound muscle movement training. They are an auxiliary tool in weightlifting and fitness exercises.

[0003] In the prior art, dumbbells are generally divided into fixed and adjustable types. Fixed dumbbells are welded as a single piece and cannot be adjusted in weight. Adjustable dumbbells require turning the nut to release the limiting position of the iron plate, so that the iron plate can be removed from the dumbbell bar. By increasing or decreasing the number of iron plates, the weight of the dumbbell can be changed. This process is quite cumbersome. Therefore, this application proposes an insert-plate dumbbell.

It should be noted that in the embodiment of this application, the connecting plates 11 are fixed on the outer walls of both ends of the fixed rod 1, and a rubber pad is provided at the middle position of the fixed rod 1, which serves as an anti-slip and protective pad.

[0025] The first counterweight 3 is set on the outer wall of one side of the connecting piece 11. The first counterweight 3 is connected to the fixing rod 1 through the locking screw 2.

[0026] The second counterweight 4 is disposed on one side of the outer wall of the first counterweight 3, and the second counterweight 4 is in close contact with the first counterweight 3. Threaded holes 13 are provided on the outer walls of both ends of the fixing rod 1, and the threaded holes 13 are adapted to the locking screw 2. It should be clear that in this application, when additional counterweight is required, the weight is increased by adding the first counterweight 3 and the second counterweight 4, and the first counterweight 3 and the second counterweight 4 are fixed to the fixing rod 1 by the locking screw 2. It should also be clear that in this application, the connecting piece 11, the first counterweight 3, and the second counterweight 4 can be of various shapes, such as circular, elliptical, pentagonal, or hexagonal. Since these are existing technologies, they will not be described in detail here.

[0027] Lifting holes 12 are provided on the outer front walls of the connecting piece 11, the first counterweight 3, and the second counterweight 4. The lifting holes 12 have an arc-shaped structure. It should be clear that in this application, the lifting holes 12 are provided on the outer front walls of the connecting piece 11, the first counterweight 3, and the second counterweight 4. The lifting holes 12 are on the same axis and are provided to facilitate the removal of the first counterweight 3 and the second counterweight 4.

[0028] The connecting piece 11, the first counterweight 3, and the second counterweight 4 have multiple arc-shaped grooves 42 and fixing grooves 33 on one side of their outer walls. The fixing grooves 33 and the arc-shaped grooves 42 are formed along the axis of the fixing rod 1. The first counterweight 3 has a slot 31 on one side of its outer wall, and the second counterweight 4 has an installation groove 43 on one side of its outer wall. The slot 31 is located between two fixing grooves 33, and the installation groove 43 is located between two slots 31. The slots 31 and the installation grooves 43 are adapted to the locking screw 2. A fixing block 32 is installed on one side of the outer wall of the first counterweight 3, and an arc-shaped block 41 is installed on one side of the outer wall of the second counterweight 4. The fixing block 32 is adapted to the fixing groove 33, and the arc-shaped block 41 is adapted to the arc-shaped groove 42. It should be clearly understood that, in this embodiment, regardless of whether the first counterweight 3 or the second counterweight 4 is connected to the connecting piece 11, the arc-shaped block 41 and the fixing block 32 can be inserted into the arc-shaped groove 42 opened on the connecting piece 11, and the fixing block 31 and the arc-shaped block 41 can be freely inserted into the fixing groove 33 and the arc-shaped groove 42. It should also be clearly understood that, in this embodiment, slots 31 and mounting grooves 43 are opened on the outer walls of the first counterweight 3 and the second counterweight 4, and fixing blocks 32 and arc-shaped blocks 41 are installed on the first counterweight 3 and the second counterweight 4. Therefore, the first counterweight 3 and the second counterweight 4 form two sets of counterweights.
