Description
The utility model relates to a kind of dumbbell, and particularly a kind of dumbbell that has variable pouring weight belongs to and not rely on thrust and grow or strengthen the muscle of human body or the exercise equipment in joint.
Along with body building popularize and deeply, dumbbell is used by increasing people as the assistive device of sports.At present, the dumbbell that people use mostly is integral structure, and two ends are hammer body, and middle thin part is a handle, fixedlys connected between hammer body and the handle.Though the dumbbell good integrity of this structure, weight is non-adjustable, can not satisfy the instructions for use of people to the Different Weight dumbbell.For addressing this problem, people had once designed multiple Weight-adjustable dumbbell, and as increasing the counterweight of identical weight on the hammer body of two ends, the two is directly by being threaded, or is connected by bolt.But there is the shortcoming that demolition, installation are wasted time and energy, simultaneously, balance weight body is easily loosening even deviate from the use, causes and damages.
The dumbbell that provides a kind of weight adjustable is provided the utility model purpose, and easy accessibility, safe in utilization, overcomes above-mentioned shortcoming of the prior art.
The purpose of this utility model can be achieved through the following technical solutions:
The dumbbell that weight is adjustable, comprise dumbbell body and balance weight body in the composition, the dumbbell body is made of hammer body and handle, middle thin part is a handle, hammer body is located at the handle two ends, improvements of the present utility model be between hammer body and the balance weight body for boss and groove fit, have connecting hole in direction perpendicular to the groove inwall, and have the locating slot relative on the boss that groove is mated with the connecting hole position.Be provided with the location lockable mechanism in connecting hole and the locating slot, the realization hammer body is connected with balance weight body.
The dumbbell that above-mentioned weight is adjustable, said location lockable mechanism can be made up of stage clip, alignment pin, catch and handle, and alignment pin places connecting hole, and its lower end can extend out to the locating slot that is located on the boss from connecting hole, and upper end and handle join.Compression spring sleeve is at alignment pin middle part, and its lower end is positioned on the alignment pin boss, and the upper end is provided with catch, and alignment pin convex clip to the distance of catch is not less than alignment pin and stretches out length in groove.
Said location lockable mechanism can also be made up of stage clip, positioning bead, catch, and the positioning bead bottom places the locating slot on connecting hole top, bottom and the stage clip that the upper end is positioned at connecting hole to join, and the stage clip upper end is provided with catch.
The dumbbell that above-mentioned weight is adjustable, said hammer body are the cylinder that the axle center has round recessed, and balance weight body is the cylinder that the axle center is provided with the boss platform, and locating slot is the cannelure around boss platform circumference.
The dumbbell that above-mentioned weight is adjustable, the mating surface place of said balance weight body and hammer body is embedded with rubber washer, so that the two closely cooperates.
The utility model is by demolition, installation balance weight body promptly and flexible modulation dumbbell weight has satisfied the incremental demand of exercising of user, and is safe and reliable.
Fig. 1 is the profile of the utility model embodiment 1.
Fig. 2 is the profile of the utility model embodiment 2.
Fig. 3 is that the A of Fig. 2 is to structural representation.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Referring to Fig. 1, Fig. 2, the utility model comprises balance weight body 1 and the dumbbell body that is made of hammer body 2 and handle 3 in forming, and middle thin part is a handle, and its outer surface has concavo-convex decorative pattern, produces effect anti-skidding and attractive in appearance simultaneously.Hammer body 2 is located at handle 3 two ends respectively, hammer body 2 can be designed to the cylinder that the axle center has cylinder shape groove 4, and balance weight body 1 is provided with the oblate cylinder of cylindrical boss 5 for the axle center, and the groove on the hammer body 2 matches with boss on the balance weight body 1.Direction perpendicular to recess sidewall on hammer body 2 has connecting hole 6, and has the locating slot 7 relative with connecting hole 6 positions on the boss 5 that groove 4 is mated.The location lockable mechanism is installed in connecting hole 6 and the locating slot 7, and realization hammer body 2 is connected with balance weight body 1.
Can be embedded with rubber washer 15 at the mating surface place of balance weight body and hammer body, so that the two closely cooperates.
Below adopt the embodiment of two kinds of different location lockable mechanism modes for the utility model.
Embodiment one:
Referring to Fig. 1, the structure of present embodiment balance weight body 1 and dumbbell body as mentioned above, its location lockable mechanism adopts alignment pin locking mode.Specifically, this location lockable mechanism is made up of stage clip 8, alignment pin 9, catch 10 and handle 11, and alignment pin 9 places connecting hole 6, and the lower end extend out to the groove 4 from the connecting hole bottom.After adding balance weight body, its lower end from connecting hole stretch be located on the boss 5 to locating slot 7, alignment pin 9 upper ends and handle 11 join.Stage clip 8 is enclosed within alignment pin 9 middle parts, and its lower end is positioned on the alignment pin convex clip 12, and the upper end is provided with the catch 10 that is fixed on the hammer body 2, in case alignment pin 9 is deviate from from connecting hole 6.Alignment pin convex clip 12 to the distance of catch 10 is stretched out length in groove 4 greater than alignment pin 9.Handle 11 upper ends highly do not exceed hammer body 2 outer surfaces, damage to prevent to cause in the use.
For realizing quick demolition, installation counterweight, locating slot 7 is designed to cannelure, its width and alignment pin 9 diameters coupling around boss platform circumference.
When the user need be installed balance weight body additional, handle 11 is upwards mentioned, drive alignment pin 9 simultaneously and move upward, the alignment pin lower end is withdrawed from from hammer body groove 4.At this moment, the boss 5 of balance weight body 1 is assembled among the hammer body groove 4, the annular positioning groove that is located on the balance weight body boss 5 is relative with connecting hole 6 positions, release handle 11 then, under the effect of elastic force, alignment pin 9 moves downward, and locating slot 7 bottoms to the balance weight body boss 5 are pushed up in its end, just finishes installing additional of balance weight body 1 this moment.
In the time of need pulling down balance weight body 1, handle 11 is upwards mentioned, alignment pin 9 moves upward, and deviates from the locating slot 7 of its lower end from balance weight body boss 5, balance weight body 1 can be taken out.
Present embodiment only can realize that with an alignment pin retaining mechanism balance weight body is connected with the safety of hammer body, and cost of manufacture is low.
Embodiment two:
Referring to Fig. 2,3, the balance weight body of present embodiment and dumbbell body structure are substantially the same manner as Example 1, and its location lockable mechanism adopts the hoodle locking mode.This mechanism is made up of stage clip 8, positioning bead 13, catch 10, and positioning bead 13 bottoms place the locating slot 7 on connecting hole 6 tops, and locating slot 7 can be the cannelure around boss platform circumference, and its width is less than the positioning bead diameter.Bottom and stage clip that positioning bead 13 upper ends are positioned at connecting hole join, and the stage clip upper end is provided with catch 10.The outer sheet rubbers 14 that embed of catch 10 can play attractive in appearance and further prevent the effect that stage clip 8 is deviate from.
