DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Reference Figures 1-3 As shown in Figures 1-3 , an embodiment provided by the present utility model is an adjustable dumbbell rack for strength training, which includes a fixed rack 1. A fixed seat 2 is fixedly connected to the top of the fixed rack 1. A card slot 3 is provided inside the fixed seat 2. A fixing plate 4 is fixedly connected to the top of the fixed seat 2. A connecting frame 5 is fixedly connected to the top of the fixing plate 4. A clamping bead 6 is slidably connected inside the connecting frame 5. A support column 7 is fixedly connected inside the connecting frame 5. A first spring 8 is sleeved on the outer wall of the support column 7. One end of the first spring 8 is fixedly connected inside the connecting frame 5, and the other end of the first spring 8 is fixedly connected to the outer wall of the clamping bead 6. A sliding groove 9 is provided inside the fixed rack 1.

[0033] Specifically, when using this dumbbell rack, place the dumbbell above the fixed seat 2. During this process, the crossbar of the dumbbell will contact the clamping bead 6 on the top of the fixed seat 2, causing the clamping bead 6 to receive force and slide into the connecting frame 5. At the same time, the clamping bead 6 applies pressure to the first spring 8 connected to its outer wall, resulting in the contraction of the first spring 8 inside the connecting frame 5. Subsequently, place the crossbar of the dumbbell into the card slot 3. At this time, the first spring 8 rebounds due to the release force, thereby pushing the clamping bead 6 to reset. In this way, the clamping bead 6 is fixed above the dumbbell, restricting its movement, effectively fixing the dumbbell, and ensuring its stability and safety during use.

[0034] Reference Figure 1 and Figure 4 As shown in Figure 1 and Figure 4 , a sliding table 10 is provided inside the fixed rack 1. The sliding table 10 is slidably connected inside the sliding groove 9. A connecting component is provided at the bottom of the sliding table 10 for supporting function. The connecting component includes a support frame 11. The support frame 11 is fixedly connected to the bottom of the sliding table 10. A rotating rod 12 is rotatably connected to one side of the sliding table 10. A connecting block 13 is rotatably connected to one side of the rotating rod 12. A support frame 14 is fixedly connected to the bottom of the sliding table 10. A support block 15 is rotatably connected inside the support frame 14. One end of a second spring 16 is fixedly connected to one side of the support block 15.

[0035] Specifically, when it is necessary to adjust the length of the tabletop of the dumbbell rack, it can be achieved by pulling the sliding table 10. The sliding table 10 slides inside the sliding groove 9 under force until the sliding table 10 moves outside the fixed rack 1. At this time, the fixed rack 1 releases the rotating rod 12 to make it rotate. At the same time, the rotating rod 12 drives one side of the connecting block 13 to rotate, resulting in the contraction of the second spring 16 connected to the other side of the connecting block 13.

[0036] Reference Figure 1 and Figure 4, the other end of the second spring 16 is fixedly connected to one side of the connecting block 13. One side of the support frame 11 is rotatably connected to a bracket 17. One side of the bracket 17 is rotatably connected to a connecting rod 18. One side of the connecting rod 18 is rotatably connected to one side of the rotating rod 12. One side of the support frame 11 is fixedly connected to a baffle 19. A slide rail 20 is fixedly connected inside the fixed frame 1. The side wall of the baffle 19 is slidably connected inside the slide rail 20.

[0037] Specifically, after the sliding table 10 stops moving, the second spring 16 releases its force and rebounds, causing the connecting block 13 and the rotating rod 12 to return to their original positions, clamping the rotating rod 12 outside the fixed frame 1. In addition, the rotating rod 12 will also drive the connection on the outer wall of the connecting rod 18 to rotate. The connecting rod 18 is stressed to drive the bracket 17 to rotate until the bracket 17 is blocked by the baffle 19 and stabilized on the ground, so that the tabletop length of the dumbbell rack can be effectively adjusted to ensure stable support and suitable use space under different requirements.

[0038] Working principle: During the use of this dumbbell rack, when placing the dumbbell, first place the dumbbell above the fixed seat 2. In this process, the crossbar of the dumbbell will contact the bead 6 on the top of the fixed seat 2, causing the bead 6 to be stressed and slide into the connecting frame 5. At the same time, the bead 6 will be stressed to squeeze the first spring 8 connected to its outer wall, causing it to contract inside the connecting frame 5. At this time, place the crossbar of the dumbbell into the card slot 3, and the first spring 8 rebounds by unloading the force, thereby driving the bead 6 to return to its original position, so that the bead 6 is stuck above the dumbbell to limit it, thus achieving the effect of fixing the dumbbell. When it is necessary to adjust the tabletop length of the dumbbell rack, the sliding table 10 can be pulled to make it slide inside the chute 9 under force. When the sliding table 10 moves out of the fixed frame 1, the rotating rod 12 is released and rotates. At the same time, the rotating rod 12 drives the connecting block 13 connected to one side to rotate. The connecting block 13 is stressed to drive the second spring 16 connected to one side to contract. Subsequently, when the sliding table 10 stops moving, the second spring 16 rebounds by unloading the force, thereby driving the connecting block 13 and the rotating rod 12 to return to their original positions, making the rotating rod 12 stuck outside the fixed frame 1. At the same time, the rotating rod 12 will also drive the connecting rod 18 connected to its outer wall to rotate. The connecting rod 18 is stressed to drive the bracket 17 connected to one side to rotate. When the bracket 17 rotates to a certain position, it will be blocked by the baffle 19, so that the bracket 17 stands on the ground for support, thus achieving the effect of adjusting the tabletop length of the dumbbell rack.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
