In addition, above-mentioned first threaded rod 13 can be with integrated connection with the screw thread of the first dumbbell block 2.
Similarly, it is threadedly coupled between above-mentioned second threaded rod 14 and the second dumbbell block 3, in order to be incited somebody to action when dumbbell is not used
Second threaded rod 14 and the second dumbbell 4 are dismantled, and then preferably save the floor space of dumbbell.
In addition, above-mentioned second threaded rod 14 can be with integrated connection with the second dumbbell block 3.
Based on above-mentioned, the operation principle of dumbbell of the present invention is：
Referring to Fig. 4, Fig. 4 is the structural representation after dumbbell increase weight of the present invention.As Figure 1-4, using preceding first accurate
Get the first dumbbell block 2, the second dumbbell block 3 and dumbbell bar 1 ready, and the first dumbbell block 2 and the second dumbbell block 3 are connected to dumbbell bar
1 two ends；Prepare multiple dumbbells 4, and be put together at one side of user；As shown in figure 4, when user needs reinforcing
When, a pair of dumbbells 4 are taken out, one of dumbbell 4 is socketed on outside the first dumbbell block 2, and make the inner spiral groove of dumbbell 4
External spiral male cooperation with the first dumbbell block 2 is connected, and then dumbbell 4 is fixed on the first dumbbell block 2；Then will be another
Individual dumbbell 4 is socketed on outside the second dumbbell block 3, and matches somebody with somebody the inner spiral groove of dumbbell 4 and the external spiral projection of the second dumbbell block 3
Connection is closed, and then dumbbell 4 is fixed on the second dumbbell block 3；
When user needs to continue to reinforce, a pair of dumbbells 4 are further taken out, one of dumbbell 4 is socketed on first
Outside dumbbell 4 on dumbbell block 2, and by the cooperation between inner spiral groove and external spiral projection, make two on the first dumbbell block 2
Dumbbell 4 interfixes；Then another dumbbell 4 is socketed on outside the dumbbell 4 on the second dumbbell block 3, and by interior spiral shell
Cooperation between spin slot and external spiral projection, makes two dumbbells 4 on the second dumbbell block 3 interfix；By that analogy, user
The number of dumbbell 4 can be added according to the size of required power；
Similarly, when user needs to reduce stress, rotary dumbbell set 4, with this by removing inner spiral groove and external spiral
Matching relationship between projection, makes dumbbell 4 depart from dumbbell；Therefore, user can also reduce mute according to the size of required power
The number of bell set 4.
From the foregoing, dumbbell of the present invention is by setting dumbbell 4, and in setting inner spiral groove and external spiral on dumbbell
Projection, and external spiral projection is set outside the first dumbbell block and the second dumbbell block, user is only needed by being socketed and reversing
Action is capable of achieving reinforcing and subtracts the effect of power, that is, improve the agility of replacing parts during dumbbell use, Jin Erti
The service efficiency of dumbbell high；Further, since the dumbbell 4 needed for being provided with reinforcing and subtracting power, therefore using in dumbbell
Put by by the concentration of dumbbell 4 in journey, realize the effect for reducing floor space.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Limitation, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and design of the invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.This hair
Bright protection domain should be determined by the scope of protection defined in the claims.
