[0038] like Figure 1-9 As shown in the figure, this utility model discloses a novel speed-adjustable dumbbell assembly, which includes a housing 1, a grip bar 2 placed inside the housing 1, and several sets of different dumbbell plates 3. The grip bar 2 is provided with an elastic locking structure 4, the dumbbell plates 3 are provided with locking grooves 5, the grip bar 2 is provided with a grip part 6, and both ends of the grip bar 2 are provided with end caps 7. The grip bar 2 is provided with an unlocking mechanism 8 inside, and the grip part 6 can be controlled by the unlocking mechanism 8 to open or lock the elastic locking structure 4.

[0039] The elastic locking structure 4 includes several locking pieces 9 slidably connected to the grip rod 2. Each locking piece 9 has several locking blocks that engage with locking grooves 5. The end cap 7 has a fixing post 10, which is connected to an abutment block 11 via a spring. The abutment block 11 abuts against the locking pieces 9. An arc-shaped groove 12 is formed on each locking piece 9, which can engage with the unlocking mechanism 8.

[0040] The gripping part 6 includes several gripping rods 13 movably connected to the gripping rod 2. Each gripping rod 13 has a clearance groove 14 at its position. A flexible collar 15 is connected to the outer part of the gripping rod 13, and the inner part of the gripping rod 13 is engaged with the unlocking mechanism 8. The flexible collar 15 can fix the gripping rod 13, and the flexible collar 15 can drive the several gripping rods 13 to rotate along the axis of the gripping rod 2.

[0041] The unlocking mechanism 8 includes a plurality of unlocking rods 16 that are slidably connected to the end cover 7. A spring is provided between the unlocking rods 16 and the end cover 7. The unlocking rods 16 are movably connected to the grip part 6, and the grip part 6 can drive the unlocking rods 16 to move.

[0042] Through the aforementioned technical features, when using this dumbbell plate set 3, first open the housing 1, take out the grip bar 2, select the desired weight of the dumbbell plate set 3, hold the grip part 6, and insert the end of the grip bar 2 into the appropriate hole in the middle of the dumbbell plate set 3. At this time, the locking pieces 9 and locking blocks in the elastic locking structure 4, under the outward force of the abutment block 11, are locked one by one into the locking grooves 5 in the counterweight plate 18 and the sealing plate 19. After completion, flip the grip bar 2 with the dumbbell plate set 3 at one end, insert the other end of the grip bar 2 into the corresponding dumbbell plate set 3, and the assembly is complete. Then it can be used normally. This achieves the technical function of rapid assembly.

[0043] When the dumbbell assembly is finished using or needs to be removed, place the grip bar 2 with dumbbell plates 3 at both ends vertically, insert one end of the dumbbell plate assembly 3 into the corresponding groove inside the housing 1, and rotate the flexible collar 15 by 45°. The flexible collar 15 drives the grip bar 13, which in turn drives the unlocking lever 16, which is engaged with the grip bar 13, to rotate 45° around the axis of the grip bar 2. This causes the part of the unlocking lever 16 located at the elastic engagement structure 4 to slide into the arc-shaped groove 12. At this time, tighten the flexible collar 15, which drives the grip bar 13 to move inward, thereby moving the unlocking lever 16 and causing the engagement piece 9 and engagement block to disengage from the engagement groove 5. While maintaining this posture, pull out the grip bar 2 to complete the removal of one end of the dumbbell plate assembly 3. After completion, release the flexible collar 15 and repeat the above operation to complete the removal of the dumbbell plate assembly 3 at the other end of the dumbbell assembly. This achieves a quick disassembly function.

[0044] When the dumbbell plate set 3 is used, in addition to the existing dumbbell's effect on arm strength training, when the arm needs to rest or in other situations, the hand can tighten and loosen the flexible collar 15, which can drive the movement of the unlocking rod 16 that is not in cooperation with the elastic locking structure 4, thereby achieving the function of training hand grip strength.

[0045] Optionally, the grip bar 2 is provided with a number of air holes 17.

[0046] It can blow on your hands and arms while exercising your grip strength, keeping your hands dry.

[0047] Optionally, the dumbbell plate set 3 includes a number of weight plates 18 and a number of blocking plates 19, the sum of the number of weight plates 18 and the number of blocking plates 19 being a fixed value.

[0048] Ensure that the same grip bar 2 can be used with dumbbell plates of different weights 3.

[0049] Optionally, the outer edges of the counterweight plate 18 and the sealing plate 19 are both polygonal structures with chamfers, and the inner edges of the counterweight plate 18 and the sealing plate 19 are both polygonal structures with chamfers.

[0050] It makes it easier to determine the angle when inserting the grip 2, making installation easier.

[0051] Optionally, the box body 1 is provided with a handle 20 and several buckles 21.

[0052] It is easy to carry when not in use.

[0053] An exemplary embodiment of the application scenario:

[0054] When using the dumbbell plate set 3, first open the box 1, take out the grip bar 2, select the desired weight of the dumbbell plate set 3, hold the grip part 6, and insert the end of the grip bar 2 into the appropriate hole in the middle of the dumbbell plate set 3. At this time, the snap-fit ​​pieces 9 and snap-fit ​​blocks in the elastic snap-fit ​​structure 4 are snapped into the snap-fit ​​grooves 5 in the counterweight plate 18 and the sealing plate 19 one by one under the outward force of the abutment block 11. After completion, flip the grip bar 2 with the dumbbell plate set 3 at one end, insert the other end of the grip bar 2 into the corresponding dumbbell plate set 3 to complete the assembly, and then it can be used normally.

[0055] When the dumbbell assembly is finished or needs to be removed, place the grip bar 2 with dumbbell plate assemblies 3 at both ends vertically, insert one end of the dumbbell plate assembly 3 into the corresponding groove inside the housing 1, and rotate the flexible collar 15 by 45°. The flexible collar 15 drives the grip bar 13, which in turn drives the unlocking rod 16, which is engaged with the grip bar 13, to rotate 45° around the axis of the grip bar 2. This causes the part of the unlocking rod 16 located at the position of the elastic engagement structure 4 to slide into the arc groove 12. At this time, grip the flexible collar 15 tightly, and drive the grip bar 13 to move inward, thereby driving the unlocking rod 16 to move and causing the engagement piece 9 and engagement block to disengage from the engagement groove 5. At this time, while maintaining this posture, pull out the grip bar 2 to complete the disassembly of one end of the dumbbell plate assembly 3. After completion, release the flexible collar 15 and repeat the above operation to complete the disassembly of the other end of the dumbbell assembly 3.

[0056] When the dumbbell plate set 3 is used, in addition to the existing dumbbell's effect on arm strength training, when the arm needs to rest or in other situations, the hand can tighten and loosen the flexible collar 15, which can drive the movement of the unlocking rod 16 that is not in cooperation with the elastic locking structure 4, thereby achieving the function of training hand grip strength.
