Abstract
The utility model belongs to a physical training apparatus, particularly a counterpoise assembly of a body-building machine. The counterpoise assembly of the body-building machine of the utility model is composed of a machine frame, a fixed pulley, a steel wire A, a sliding bar, a counterpoise, a connector pin, a fixing seat, a steel wire B and a movable pulley. One end of the steel wire A is connected with the movable pulley, and the other end, stepping over the fixed pulley, is connected with a traction force end. One end of the steel wire B is connected with the sliding bar of the counterpoise, and the other end, passing by the movable pulley, is fixed on the fixing seat of the body-building machine. Two or more than two movable pulleys can also be used in the utility model. The utility model has the advantages that the weight of the counterpoise is reduced because the movable pulley is used; the material is saved, and the cost of the body-building machine is reduced.
Description
The utility model belongs to the apparatus of physical training, especially belongs to the balancing weight assembly of body exercising machine.
The general gravity direction by one or more fixed pulleys change balancing weights of present body exercising machine comes having an effect of balance person taking exercise, because each one strength difference, balancing weight reaches tens, wastes the material of balancing weight, has increased the cost of body exercising machine.
The purpose of this utility model is to provide a kind of body exercising machine balancing weight assembly that utilizes movable pulley to reduce balancing weight weight, and the cost of body exercising machine is descended.
Technical solution adopted in the utility model is: the body exercising machine balancing weight assembly of being made up of frame, fixed pulley, steel wire A, guide rod, sliding bar, balancing weight, latch, holder, it also comprises steel wire B and movable pulley, the in succession center of movable pulley of steel wire A one end, the other end links to each other with the pulling force end by fixed pulley, steel wire B one end connects on the sliding bar of balancing weight, and the other end is walked around on the holder that movable pulley is fixed on body exercising machine.
The principle that the utility model adopted is: that utilizes that movable pulley makes steel wire A stressedly is the stressed twice of steel wire B, balancing weight of promptly every increase, and the person taking exercise need increase the power that is twice in balancing weight.
Advantage of the present utility model is: utilize movable pulley to make the weight saving of balancing weight, save material, reduce the complete machine cost.

Fig. 2 is the A-A cutaway view of Fig. 1
Fig. 3 is a structural representation of the present utility model
Fig. 4 is the structural representation of the balancing weight assembly of two movable pulleys
1 frame, 2 fixed pulleys, 3 steel wire A, 4 guide rods, 5 sliding bars, 6 balancing weights, 7 latches wherein
8 holders, 9 steel wire B, 10 movable pulleys, 11 steel wire C, 12 movable pulley B
Below in conjunction with view the utility model is described in detail
The balancing weight assembly that is existing body exercising machine as shown in Figure 1 and Figure 2 is made up of frame 1, fixed pulley 2, steel wire A3, guide rod 4, sliding bar 5, balancing weight 6, latch 7, holder 8, three holes are arranged on the balancing weight, be enclosed within respectively on two guide rods 4 and the sliding bar 5, many through holes on the sliding bar 5, there is a drag hook top, is used for overlapping steel wire.(or a stressed member is arranged on the sliding bar 5, be used to bear having an effect of person taking exercise), steel wire A3 strides across the end of having an effect that fixed pulley 2 is connected to the person taking exercise, under the balancing weight groove is arranged, and it is corresponding with the hole on the sliding bar 5, latch 7 inserts in the hole of sliding bar from the groove of balancing weight, like this when person taking exercise's strength is enough big, the balancing weight of latch more than 7 will be followed sliding bar and be sling together, and the balancing weight of latch below 7 is motionless, the person taking exercise decides several balancing weights of needs according to the strength of oneself, and guide rod 4 makes the balancing weight of slinging not produce swing.
As shown in Figure 3, the utility model is to have increased a movable pulley 10 and a steel wire B9 on existing body exercising machine balancing weight assembly, hook and fixed mount are arranged on the movable pulley 10, the in succession hook of movable pulley of steel wire A one end, the other end strides across fixed pulley and links to each other with the end of having an effect, the in succession sliding bar of balancing weight of steel wire B9 one end, the other end strides across movable pulley 10 and is fixed on the holder 8, and the weight of balancing weight is half of existing balancing weight weight.
Owing to use movable pulley, increased the stressed of steel wire A, steel wire A stressed is the stressed twice of steel wire B (do not consider movable pulley etc. weight), steel wire B goes up the weight of a balancing weight of every increase, steel wire A goes up increases the power that doubles balancing weight gravity, so just can make the weight saving of balancing weight arrive half that has balancing weight weight now, save material, the body exercising machine cost is descended.
In like manner as shown in Figure 4, also can use two above movable pulleys, further reduce the weight of joining piece, if n is the quantity of movable pulley, the weight G of balancing weight is new=
G is old.
