It includes connecting rod, handle cover, two sets of balancing disk (ball), gravity pearl, nut, two sets of balancing disks symmetry are respectively fixed at the connecting rod both ends, and the handle ways is in the middle of the connecting rod, and the nut is used for fixing balancing disk (ball) at the connecting rod both ends, the gravity pearl balancing disk (ball) of can packing into. When the user perhaps moved with this dumbbell weight lifting, the gravity pearl can accompany the dumbbell to move together, can increase the rhythm of motion, the unit weight of gravity pearl is little, and the user can increase and decrease gravity pearl quantity gradually and improve the motion effect.

Description

A kind of novel weight-adjustable dumbbell

Technical field

The utility model relates to a kind of device of body-building, is the dumbbell of energy weight lifting and fitness-assisting specifically.

Background technology

At present, known dumbbell mainly contains two kinds, and one is fixed weight dumbbell, and another kind is weight-adjustable dumbbell.The usual parts by weights of fixed weight dumbbell is that the heavy dumbbells such as 6,8,12 pounds etc. light dumbbells and 10,15,20 kilograms are multiple.This dumbbell due to weight be fixing, all users need the dumbbell preparing multiple Different Weight, like this very inconvenient, and cost is also high simultaneously.Weight-adjustable dumbbell is made up of dumbbell bar, dumbbell plate and dumbbell nut, similar to barbell, and this dumbbell has three or more dumbbell plates usually, can increase and decrease dumbbell plate quantity and carry out adjustable dumbbell weight during use.Because needs nut fixes dumbbell plate, therefore bother when regulating weight.These two kinds of dumbbells, fixed weight dumbbell due to weight difference between Different Weight type apart from large and adjustable dumbbell because single dumbbell plate weight is large, therefore when regulating weight, weight fluctuations span is comparatively large, easily causes the inadaptable even possibility of user injured.Meanwhile, fitness-assisting function is made to have a greatly reduced quality.

Summary of the invention

In order to overcome the large deficiency of existing dumbbell weight increase and decrease span, the utility model provides a kind of novel weight-adjustable dumbbell, this dumbbell not only has the function of weight lifting and fitness-assisting, and can increase and decrease dumbbell weight by a small margin, adds timing during motion simultaneously.

The utility model solves the scheme that its technical problem adopts: weight-adjustable dumbbell provided by the present invention comprises connecting rod, taper knob, two set of weights dishes (ball), gravity pearl, nut; Two set of weights dishes respectively symmetry are fixed on connecting rod two ends, and taper knob is enclosed within the middle of connecting rod, and nut is used for balancing disk (ball) to be fixed on connecting rod two ends; Gravity pearl can load balancing disk (ball).When user is with this dumbbell weight lifting or motion, gravity pearl can move together with dumbbell, can increase the rhythm of motion; The Unit Weight of gravity pearl is little, and user can increase and decrease gravity pearl quantity gradually to improve movement effects.

The beneficial effects of the utility model are, can trace increase and decrease dumbbell weight, add the timing of motion, structure is simple.

Detailed description of the invention

In FIG, taper knob (2) is enclosed within the mid portion of connecting rod (1), balancing disk (3), from the two ends at two ends cover upper connecting rod (1), is screwed into the two ends of connecting rod (1) with fixed weight dish (3) with nut (4).Gravity pearl (11) can pass through lid (5) and puts into balancing disk or therefrom take out.The two ends of connecting rod are preferably consistent with the thickness of balancing disk, such nut and balancing disk better with contacting of connecting rod, fixed effect also can be better.

In the embodiment shown in Figure 2, balancing disk (3) is fixed on connecting rod (1) two ends by nut (4), gravity pearl (11) is placed in balancing disk (3), and it is inner that nut (4) gos deep into connecting rod (1).Connecting rod (1) its body of rod is as shown in Figure 3 hollow, the inner screw thread with matching with nut in its two ends.

In the embodiment shown in fig. 10, often organize two balancing disks (3) for two groups and be separately fixed at connecting rod (1) two ends, two balancing disks (3) are fixed on connecting rod (1) two ends by nut (4) together, wherein be enclosed within connecting rod (1) by inner balancing disk (3), outer balancing disk (3) is not be enclosed within connecting rod (1) tail end, but being enclosed within nut (4), the tail end of nut (4) is screwed in the screw thread in connecting rod (1) tail end.The circular hole (6) of outer balancing disk (3) can suitably change can be better with the contact of nut (4).

In the embodiment shown in fig. 11, weighted spherical ball (9) is connected to the two ends of connecting rod 2 (10), the two ends of connecting rod (1) are stretched in weighted spherical ball (9), nut (4) is screwed into the two ends of connecting rod 2 (10) from weighted spherical ball (9) outside, and wherein the body of rod of connecting rod 2 (10) is not hollow.This embodiment is simple form of the present utility model, and gravity pearl (11) can be put into from the hole outside weighted spherical ball or take out, and then uses nut (4) to be screwed into connecting rod 2 (10) tail end from this hole.Gravity pearl (11) can be replaced in this embodiment with the thing such as water, sand.
