The utility model content
The purpose of this utility model is to overcome the deficiency of prior art, a kind of whole locking safety is provided, places reliablely, and the balancing weight suit is convenient, fast, the dumbbell that weight distribution is even, weight is adjustable.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of dumbbell of adjustable weight, and comprise and hold body, two balancing weights, hold the lever that the body middle part is provided with available grasped, hold the body both sides and be provided with left and right bearing; Be provided with the lockhole of snap close balancing weight on the bearing corresponding to the position of lever; Balancing weight is made up of the some weight stacks that are superimposed, and balancing weight removably is nested with on bearing; Be provided with the locking-bar suitable with lockhole, it is bright that locking-bar is provided with hand, has on the weight stack and the bright suitable through hole of hand, and locking-bar passes the through hole snap close in lockhole.
Be respectively arranged with suitable groove, projection on described bearing and the weight stack mating surface.
Be respectively arranged with on the two relative mating surfaces of described weight stack can be suitable groove, projection.
The bright cross section of described hand is non-circular.
The bright locating piece that comprises integrated cylinder body and two symmetries of described hand, locating piece is the ennation of cylinder body lateral surface.
Described locking-bar diameter is not more than the cylinder body diameter, and less than the lever diameter.
Described locking-bar diameter equals the cylinder body diameter, and less than the lever diameter.
Described locking-bar end is provided with external screw thread, and lockhole is provided with internal thread, and external screw thread and internal thread are suitable.
Described top of holding body is provided with two wrister bars, and the both sides that two wrister bars set up lever separately, the two ends of wrister bar fixedly link with left and right bearing respectively.
Described bottom of holding body is provided with two auxiliary rods, and two auxiliary rods set up the both sides of lever separately, and the two ends of auxiliary rod fixedly link with left and right bearing respectively.
Described weight stack is identical with the bearing shape, all is non-circular.
The beneficial effects of the utility model are, have on the weight stack that is adopted with the bright suitable through hole of hand, handle cross section be non-circular, when regulating weight, the hand of only need outwarding winding is bright, add by through hole and to subtract weight stack, choose weight after, it is bright to screw hand, make that hand is bright not to be in same position with through hole, already firmly, the secure latch balancing weight; Have groove on the bearing that is adopted, weight stack is provided with groove, projection, make people can be firmly, snap close balancing weight safely, weight stack can not become flexible; The wrister bar that is adopted sets up the both sides of lever separately, makes people can play protective effect to wrist when using dumbbell; The locking-bar diameter that is adopted is identical with the bright cylinder body diameter of hand, and behind the snap close, weight stack can not become flexible; Weight stack that is adopted and bearing all are non-circular, can not roll and cause the accident of hurting sb.'s feelings.

The specific embodiment
Shown in accompanying drawing, the dumbbell of a kind of adjustable weight of the present utility model comprises and holds body 1, balancing weight 2; Hold the lever 11 that body 1 middle part is provided with available grasped; Hold body 11 both sides and be provided with left and right bearing 12; Left and right bearing 12 is symmetricly set in respectively holds body 11 both sides.
Be provided with the lockhole 121 of snap close balancing weight 2 on the bearing 12 corresponding to the position of lever 11; Balancing weight 2 is formed (being depicted as 3 on the figure) by the some weight stacks 21 that are superimposed, and balancing weight 2 removably is nested with on bearing 12.Mating surface with weight stack 21 on the bearing 12 is provided with two suitable grooves 122.Two grooves 122 lay respectively at two sides up and down of lockhole 121.Lockhole 121 is provided with internal thread.
The top of holding body 1 is provided with the both sides that two wrister bars, 13, two wrister bars 13 set up lever 11 separately, and the two ends of wrister bar 11 fixedly link with left and right bearing 12 respectively.
The bottom of holding body 1 is provided with the both sides that two auxiliary rods, 14, two auxiliary rods 14 set up lever 11 separately, and the two ends of auxiliary rod 14 fixedly link with left and right bearing 12 respectively.
Be provided with the locking-bar 3 suitable with lockhole 121, locking-bar 3 is provided with non-circular hand bright 31.Non-circular hand bright 31 comprises the locating piece 312 of integrated cylinder body 311 and two symmetries, and locating piece 312 is the ennation of cylinder body 311 lateral surfaces.Locking-bar 3 diameters are less than lever 11 diameters.Locking-bar 3 ends are provided with external screw thread, and the external screw thread of locking-bar 3 and the internal thread of lockhole are suitable.
