DETAILED DESCRIPTION

[0022] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Figure 1-Figure 7 As shown, a dumbbell that is easy to adjust comprises a rod body 1 and a counterweight 4, two ends of the rod body 1 are fixedly connected with connecting rods 3, the connecting ends of the rod body 1 and the connecting rod 3 are fixedly connected with a limiting ring 2, the outer wall of the connecting rod 3 is provided with a clamping piece, the clamping piece is arranged at the outer end of the counterweight 4, a fixing button 16 is threadedly connected on the clamping piece, and the inner wall of the clamping piece is matched and abutted against the clamping slot 15; two ends of the rod body 1 are fixed with connecting rods 3, the connecting part of the connecting rod 3 and the rod body 1 is fixed with a limiting ring 2, the connecting rod 3 is sleeved with a counterweight 4, the counterweight 4 is installed as needed, after the counterweight 4 is installed, the clamping piece is inserted from the connecting rod 3, and then the fixing button 16 is rotated and fixed on the clamping piece, the clamping piece is closely fitted with the connecting rod 3, and the fixing effect is achieved by matching and clamping the inner end of the clamping piece with the clamping slot 15, so that the number of rotations of the fixing button 16 is small, it is more convenient during installation and disassembly, and the replacement of the counterweight 4 can be more convenient for adjustment.

[0025] See also Figure 3 and Figure 5 : A groove 7 is provided on one side of the counterweight 4, and a limiting groove 8 is provided in the groove 7. A protrusion 5 is fixed on the other side of the counterweight 4, and the outer side of the protrusion 5 is fixedly connected to the limiting block 6. The protrusion 5 is matched with the groove 7, and the limiting block 6 is matched with the limiting groove 8. The outer side of the limiting ring 2 is also provided with a groove 7 and a limiting groove 8. During installation, the protrusion 5 on the counterweight 4 is inserted into the groove 7 on the other side of the counterweight 4, and the limiting block 6 is inserted into the limiting groove 8 relatively. In this way, when the whole is used for movement, whether it is up and down or left and right, the counterweight 4 will not loosen or rotate during movement, so that the movement is more stable.

[0026] See also Figure 6 The clamping member includes a fixing ring 9, one side of which is fixedly connected with a matching block 10, which is matched with the limiting groove 8, and the other side of the fixing ring 9 is fixedly connected with a clamping plate 12, and the inner side wall of the clamping plate 12 is fixedly connected with a clamping strip 14, which is matched with the clamping slot 15, and a fixing button 16 is threadedly connected and rotated on the clamping plate 12. By rotating the fixing button 16, the clamping plate 12 is pressed to match and clamp with the clamping slot 15 on the outside of the connecting rod 3. After the clamping strip 14 is clamped with the clamping slot 15, it can avoid falling off to the outside, thereby achieving a better stable fixing effect.

[0027] See also Figure 6 : The outer wall of the fixing ring 9 is fixedly connected with an extension ring 11, and the inner wall of the extension ring 11 is set against the outer wall of the counterweight 4. The extension ring 11 can increase the contact area with the outer end face of the counterweight 4, thereby achieving a better friction effect, thereby preventing the fixing button 16 from loosening, making it more stable and avoiding loosening during exercise.

[0028] See also Figure 6 : The outer wall of the fixing ring 9 located on one side of the matching block 10 is fixedly connected with a spring clip 13. The number of the spring clips 13 is set in multiples with equal spacing. When installing the fixing ring 9, the inner end is continuously pressed, and the spring clip 13 is compressed and then contracts, so that the card strip 14 and the card slot 15 can be further tightly connected, so that the fixing ring 9 can be fixed more tightly and stably.

[0029] See also Figure 6 : An arc groove is provided at the outer end of the fixing button 16, and there are multiple arc grooves with equal spacing. The arc groove provided at the outer end of the fixing button 16 can facilitate the user to achieve better rotation when rotating and fixing, increase the friction with the hand, and facilitate the user to rotate and fix.

[0030] When in use: first, according to the needs of the user, put the counterweight 4 on the connecting rod 3. After the counterweight 4 is set, insert the fixing ring 9 into the groove 7, insert the matching block 10 into the limiting groove 8 for locking, and then rotate the fixing button 16 to press the clamping plate 12 onto the connecting rod 3. The clamping strip 14 and the clamping groove 15 can be tightly engaged to achieve a stable effect, and the rotation stroke of the fixing button 16 is shorter, so it is more convenient to adjust the counterweight 4.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
