Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a dumbbell that can be quickly assembled and disassembled. Background Technology

[0002] Dumbbells are auxiliary equipment used in weightlifting and fitness exercises, smaller than barbells. They are simple tools for increasing muscle strength. The main material is cast iron, sometimes with a rubber coating. They are used for strength training and compound muscle exercises. Dumbbells can train single muscles; as the weight increases, multiple muscles need to be coordinated, making them suitable for compound muscle exercises.

[0003] A quick-assembly dumbbell, disclosed in publication number "CN220989526U", includes a dumbbell bar with a gripping component fixed in the middle. Dumbbell plates are mounted on both sides of the gripping component. The dumbbell bar on both sides of the gripping component has a fitting part and a threaded connection part. The fitting part holds the dumbbell plates, and the threaded connection part is located on the outside of the fitting part. A nut or dumbbell plate is externally threaded into the threaded connection part, clamping the dumbbell plate fitted into the fitting part. This quick-assembly dumbbell achieves rapid assembly and disassembly of the dumbbell.

[0004] While this patent allows for quick installation and removal of dumbbell plates by using a threaded connection, in actual use, different users have different requirements for the length of the dumbbell bar. However, this patent cannot adjust the dumbbell bar according to different users. Furthermore, when installing dumbbell plates using the threaded connection, the weight difference on both sides can easily cause the dumbbells to fall, increasing the risk of injury to the user. Therefore, improvements are needed. Utility Model Content

[0060] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a quick-assembly and disassembly dumbbell.

[0061] A quick-assembly dumbbell includes a support frame 1 and a telescopic plate 2, the telescopic plate 2 being fixedly connected to the support frame 1; it also includes: a first support groove 3 formed on the support frame 1; a second support groove 4 formed on the support frame 1; a first support column 5 disposed within the first support groove 3 and slidably connected to the first support groove 3; a second support column 6 disposed within the second support groove 4 and slidably connected to the second support groove 4; a telescopic mechanism disposed on the telescopic plate 2 for adjusting the length of the dumbbell; and a clamping mechanism disposed on the first support column 5 for quickly installing and removing the dumbbell plates.

[0062] Reference Figure 5 In a preferred embodiment, the telescopic mechanism includes: a telescopic frame 7, which is disposed on the telescopic plate 2 and fixedly connected to the telescopic plate 2; a telescopic motor 8, which is fixedly connected to the telescopic frame 7; a telescopic shaft 9, which is detachably fixedly connected to the output end of the telescopic motor 8; a telescopic gear 10, which is disposed on the telescopic shaft 9 and fixedly connected to the telescopic shaft 9; and a sliding component, which is disposed on the support frame 1.

[0063] This configuration ensures that when the telescopic motor 8 is running, it drives the telescopic shaft 9, which is detachably and fixedly connected to the output end of the telescopic motor 8, to rotate, thereby causing the telescopic gear 10, which is fixedly connected to the telescopic shaft 9, to rotate and provide power for the operation of the sliding components.

[0064] Reference Figure 5 In a preferred embodiment, the sliding component includes: a first sliding groove 11, formed on the support frame 1; a second sliding groove 12, formed on the support frame 1; a first sliding rack 13, disposed in the first sliding groove 11, slidably connected to the first sliding groove 11, meshing with the telescopic gear 10, and fixedly connected to the first support column 5; and a second sliding rack 14, disposed in the second sliding groove 12, slidably connected to the second sliding groove 12, meshing with the telescopic gear 10, and fixedly connected to the first support column 5.

[0065] This configuration allows the first sliding rack 13, which meshes with the telescopic gear 10, to slide within the first sliding groove 11, while simultaneously driving the second sliding rack 14, which meshes with the telescopic gear 10, to slide within the second sliding groove 12. This, in turn, causes the first support column 5 and the second support column 6 to slide within the first support groove 3 and the second support groove 4, thereby enabling the adjustment of the dumbbell's length.

[0066] Reference Figure 4 In a preferred embodiment, the clamping mechanism includes: a clamping cylinder 15, which is disposed inside the first support column 5 and fixedly connected to the first support column 5; a clamping rod 16, which is slidably connected to the clamping cylinder 15; a clamping rack 17, which is disposed on the clamping rod 16 and fixedly connected to the clamping rod 16; and a rotating component, which is disposed inside the first support column 5.

[0067] This configuration causes the clamping cylinder 15 to retract into the clamping cylinder 15 when it is in operation, which in turn causes the clamping rod 16, which is slidably connected to the clamping cylinder 15, to move closer to the clamping cylinder 15, thereby providing power for the operation of the rotating components.

[0068] Reference Figure 4 In a preferred embodiment, the rotating component includes: a first rotating shaft 18, disposed within the first support column 5 and fixedly connected to the first support column 5; a second rotating shaft 19, fixedly connected to the first support column 5; a first rotating gear 20, disposed on the first rotating shaft 18, rotatably connected to the first rotating shaft 18, and meshing with the clamping rack 17; a second rotating gear 21, disposed on the second rotating shaft 19, rotatably connected to the second rotating shaft 19, and meshing with the clamping rack 17; and a transmission component, disposed on the first rotating shaft 18.

[0069] This configuration causes the first rotating gear 20 to rotate on the first rotating shaft 18, which in turn causes the second rotating gear 21, which is rotatably connected to the second rotating shaft 19, to rotate, thereby driving the transmission components to operate.

[0070] Reference Figure 4 In a preferred embodiment, the transmission component includes: a first transmission gear 22, which is disposed on the first rotating gear 20, fixedly connected to the first rotating gear 20, and rotatably connected to the first rotating shaft 18; a second transmission gear 23, which is disposed on the second rotating gear 21, fixedly connected to the second rotating gear 21, and rotatably connected to the second rotating shaft 19; a transmission frame 24, which has multiple transmission frames 24 evenly disposed within the first support column 5, and fixedly connected to the first support column 5; and a connecting assembly disposed within the transmission frame 24.

[0071] This configuration causes the first transmission gear 22, which is fixedly connected to the first rotating gear 20, to rotate around the first rotating shaft 18, and causes the second transmission gear 23, which is fixedly connected to the second rotating gear 21, to rotate around the second rotating shaft 19, thereby enabling the connecting assembly to operate.

[0072] Reference Figure 4 In a preferred embodiment, the connecting assembly includes: a first connecting block 25, disposed within the transmission frame 24, slidably connected to the transmission frame 24, and meshing with a first transmission gear 22; a second connecting block 26, disposed within the transmission frame 24, slidably connected to the transmission frame 24, and meshing with a second transmission gear 23; a rectangular block 27, slidably connected to the first connecting block 25 and the second connecting block 26; and a connecting piece 28, fixedly connected to the rectangular block 27.

[0073] This configuration allows the first connecting block 25 and the second connecting block 26, which mesh with the first transmission gear 22 and the second transmission gear 23, to slide within the transmission frame 24. This allows the first connecting block 25 and the second connecting block 26 to slide within the rectangular block 27, which is fixedly connected to the connecting piece 28, thereby enabling the rapid installation and removal of the dumbbell plates.

[0074] Working principle: When using dumbbells, first start the telescopic motor 8, which drives the telescopic shaft 9, which is detachably and fixedly connected to the output end of the telescopic motor 8, to rotate. This causes the telescopic gear 10, which is fixedly connected to the telescopic shaft 9, to rotate. This causes the first sliding rack 13, which meshes with the telescopic gear 10, to slide in the first sliding groove 11. At the same time, it drives the second sliding rack 14, which meshes with the telescopic gear 10, to slide in the second sliding groove 12. This causes the first support column 5 and the second support column 6 to slide in the first support groove 3 and the second support groove 4.

[0075] When installing the connecting piece 28, first activate the clamping cylinder 15, causing the clamping rod 16, which is slidably connected to the clamping cylinder 15, to retract into the clamping cylinder 15. This causes the clamping rack 17, which is fixedly connected to the clamping rod 16, to move closer to the clamping cylinder 15, thereby causing the first rotating gear 20 to rotate on the first rotating shaft 18. This causes the second rotating gear 21, which is rotatably connected to the second rotating shaft 19, to rotate, thereby causing the first transmission gear 22, which is fixedly connected to the first rotating gear 20, to rotate around the first rotating shaft 18. This causes the second transmission gear 23, which is fixedly connected to the second rotating gear 21, to rotate around the second rotating shaft 19. This causes the first connecting block 25 and the second connecting block 26, which mesh with the first transmission gear 22 and the second transmission gear 23, to slide within the transmission frame 24, thereby causing the first connecting block 25 and the second connecting block 26 to slide within the rectangular block 27, which is fixedly connected to the connecting piece 28.

[0076] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
