A. two lug, nibs are stuck in the open recess on 5 balancing weight both sides in kettle-bell body housing, balancing weight and shell
In garden, circumferential direction is relatively unrotatable, and in initial position, all projections of rotating shaft are the sectors positioned at balancing weight both sides
The lower section in hole, at this moment lift kettle-bell body, all balancing weights all disengage with body, and what is lifted is only the weight of body itself.
B. before kettle-bell body is not mentioned, the spring base of connecting rod lower end, spring base pressure are pushed up on square drive axle
Contractive pressure spring and upper top connecting rod, locking plate is pushed up in connecting rod, and locking plate disengages positioning fluted disc.Rotating shaft is relative to body and balancing weight
In garden, circumferential direction can rotate, and realize adjustment of weight function.
C. it is that the lower end of rotating shaft and square drive axle disengage first when kettle-bell body lifts, work of the spring base in stage clip
Descending with lower pulling connecting rod and locking plate, the external tooth of locking plate is caught in the teeth groove for the positioning fluted disc being fixed on body, this
When rotating shaft opposing body be just stuck, it is impossible to rotate.
D. after kettle-bell body is put on base, the counterweight needed could be selected.When 15 pounds of the selection on button and press " OK "
During key, microprocessor control motor starts, and drives square drive axle and rotating shaft to be rotated relative to base, shell and balancing weight.Because
Locking plate on lockable mechanism disengages by the position on top to top with positioning fluted disc, and rotating shaft can opposite shell rotation.Motor exists
Rotating shaft is gone into initial position, i.e. 0 ° of position under control circuit effect.Corresponding to all projections on initial position, rotating shaft
Position is the initial position of balancing weight scallop hole.Now portable kettle-bell body, because rotating shaft disengages with square drive axle, pressing
In the presence of spring, left behind locking plate by connecting rod, locking plate external tooth blocks positioning fluted disc, and rotating shaft is no longer able to turn.Lift
Weight be body be free of balancing weight weight, only 15 pounds.
E. when on button select 20 pounds simultaneously " OK " when, microprocessor control motor start, drive square drive axle and turn
Axle turns over 30 ° of angles with respect to base, shell and balancing weight.Because the central angle of the first piece of balancing weight scallop hole in the top only has 30 °,
After 30 ° of axis of rotation, the scallop hole of uppermost projection and first piece of balancing weight in rotating shaft staggers, by first piece of balancing weight
Block.The other 4 pieces of balancing weights in lower section are because fan-shaped hole position is equal to or be more than 60 °, it is impossible to are blocked by the projection of rotating shaft；So
At this moment during portable kettle-bell body, its weight is 20 pounds.
When selecting 25 pounds on button and press " OK " keys when, motor starts, and drives square drive axle and rotating shaft with respect to base, outside
Shell, counterweight rotate 60 °, because the central angle of the scallop hole of uppermost two pieces of balancing weights is less than 60 °, after rotating shaft turns over 60 °,
Uppermost two pairs of projections are just seized uppermost balancing weight 7-1 and balancing weight 7-2 in rotating shaft；Other 3 balancing weights because
The central angle of scallop hole is both greater than 90 °, it is impossible to is blocked by the projection of rotating shaft；Therefore, at this moment portable kettle-bell when, its weight is 25
Pound.
When 30 pounds, 35 pounds or 40 pounds are being selected on button respectively and is being pressed " OK " keys when, select the operation principle of counterweight to be same as above,
Simply rotating shaft relative rotation is 90 °, 120 °, 150 ° respectively.
Above example of the present invention has advantages below：
1) using button selection weight pattern, adjustment weight is directly perceived, easy, and avoiding traditional kettle-bell weight list one can not be more
The defects of changing, it is wider to adapt to user group.
2) the interior tooth positioning device of use, it is ensured that kettle-bell axis of rotation to corresponding positions can just mention, and avoid accident from carrying kettle and make
It is stuck into rotating shaft.
3) locking mechanism is used, it is ensured that after kettle-bell body is mentioned, rotating shaft is not rotated further by, so as to ensure that balancing weight will not
Surprisingly come off after body lifts and cause security incident, will not also make hand dirty.
4) the on-chip power lithium battery in base, can also normal use in the case of without external power supply.
5) sensor is implanted in kettle-bell body, sensor is connected by the control circuit in bluetooth will base, control
Circuit can be connected by bluetooth with the APP on mobile phone.So as to calculate the heat of the cycle-index lifted, human consumption, help
Science is taken exercise.
6) parameters such as gross weight, battery electric quantity, bluetooth connection are shown using LCD display, it is very clear.
Above example of the present invention is only preferred embodiments, is not intended to limit the invention, although previous embodiment
The present invention is described in detail, for those skilled in the art, it can still be remembered to foregoing embodiments
The technical scheme of load is modified, or carries out equivalent substitution to which part technical characteristic.It is all the present invention it is spiritual and former
Within then, any modification, equivalent substitution and improvements made etc. all should be within protection scope of the present invention.
