Detailed description of the invention
The utility model is applicable to the fitness equipment of various difunctional or more functional training, such as: leg is overhanging, the difunctional exercise body-building device of introflexion, the difunctional exercise body-building device of leg abduction, adduction, difunctional arm muscle exerciser, difunctional exercise body-building device of abdominal muscle, dorsal muscles etc.
Be herein be used in that leg is overhanging with the utility model, the difunctional exercise body-building device of introflexion is described for embodiment.
As shown in Figure 1 to Figure 2, the utility model discloses a kind of function switching mechanism of fitness equipment, comprises rotating shaft 1, body frame locating shaft 2, pulley 3, steel wire rope 4, cam orientation axle 5, cam 6, swing arm 7, draws pin 8 and movement arm 9.
Rotating shaft 1 intert cam 6 wheel in the heart.
Movement arm 9 has actuating strut 91 and drive link 92.Drive link 92 is formed axle sleeve 93, axle sleeve 93 is set in rotating shaft 1.
Pin 8 is drawn to be arranged on drive link 92.
On the wheel face of cam 6, correspondence draws pin 8 to form at least two locating holes 61, by drawing pin 8 to insert in locating hole 61, makes fitness equipment be in corresponding functional status.
One end of swing arm 7 forms axle sleeve 71, and axle sleeve 71 is set in rotating shaft 1, and the other end of swing arm 7 installs guide wheel 72.
Cam orientation axle 5 is arranged on cam 6, and cam orientation axle 5 is positioned at above swing arm 7.
Body frame locating shaft 2 is arranged on the body frame 10 of fitness equipment, and body frame locating shaft 2 is positioned at above swing arm 7.
Pulley 3 is arranged on the body frame 10 of fitness equipment, and pulley 3 is positioned at above body frame locating shaft 2.
Steel wire rope 4 is around on cam 6, guide wheel 72 and pulley 3, and one end of steel wire rope 4 is fixed on cam 6, and the other end is fixed in the load of body frame 10.
Conveniently assembling is fixing, and the wheel rim of cam 6 is recessed to form groove 62 to core wheel, and one end of steel wire rope 4 is fixed on the groove 62 of cam 6.
Lay to make steel wire rope 4 and move smooth and easy and avoid being wound around, drive link 92 extends to body frame 10 direction of fitness equipment, and installs cover body 94 in the end of drive link 92, and cover body 94 covers on groove 62 place of cam 6.
When the utility model uses, as carrying out the training that bends one's legs, as shown in Figures 3 to 8, insert drawing pin 8 in the locating hole 61 of top.Fig. 3 and Fig. 4 is the original state of curl, above the actuating strut 91 leg being placed on movement arm 9, bend one's legs downwards, as dotted state in Fig. 5 and Fig. 6 curl, band moving cam 6 rotates counterclockwise, and swing arm 7 hinders location by body frame locating shaft 2, and can not rotate counterclockwise with cam 6, until the stop state of curl shown in Fig. 7 and Fig. 8, complete the action that once bends one's legs.
As for carrying out training of stretching one's legs, as shown in Fig. 9 to Figure 14, insert drawing pin 8 in the locating hole 61 of below.It is the original state of moving of stretching one's legs shown in Fig. 9 and Figure 10, below the actuating strut 91 leg being placed on movement arm 9, upwards stretch one's legs, it is the middle dotted state of moving of stretching one's legs shown in Figure 11 and Figure 12, band moving cam 6 rotates clockwise, and swing arm 7, and to rotate clockwise along with cam 6 against location by cam orientation axle 5, the stop state of the motion until stretch one's legs as shown in Figure 13 to Figure 14, completes action of once stretching one's legs.
The utility model adopts cam 6 to combine with swing arm 7, the center of cam 6 and the center superposition of swing arm 7, cam 6 there is a cam orientation axle 5, there are two or three locating holes 61, add on body frame 10 and have a body frame locating shaft 2, by regulating the position of drawing pin 8, switching between two functions realizing difunctional training airplane, agonistic muscle muscle group relative to antagonist can be realized when combining exercise, resistance pouring weight number need not be changed, meet same trainer's positive movement agonistic muscle load large, the feature that counter motion antagonist load is little, realize an actuation cycle variable force process simultaneously.
Wherein, in adjustment process, the profile radius of cam 6, by little-large-little change, according to the moment of resistance=resistance × arm of force, thus realizes moment of resistance change and changes into positive guide by traditional passive change and change, ensure sports safety and efficiency, coordinate shown in Figure 15.
Cam 6 is designed with the locating hole 61 having certain span for two or three, the pin 8 that draws realizing gear adjustment can be selected to navigate to locating hole 61, realizes the selection of motion pivoted arm relative to cam diverse location, realizes the object of the motion of movement arm both direction.
Cam orientation axle 5 and body frame locating shaft 2, determine the relative position between cam 6 and swing arm 7; Whole steel wire rope 4 one end connects load, one end connects cam 6, tension adjustment well after, there is not any gap; And no matter rotate clockwise or rotate counterclockwise, the stress point of steel wire rope 4 is all tangent with the outline of cam 6, except angle of operation very little when, the pliability of steel wire rope 4 offsets its movement travel, other any one movement angle, namely thus there is not the problem of ago idle stroke be all directly act on pouring weight load.
When drawing pin 8 to be adjusted to cam 6 times locating holes 61, do motion of stretching one's legs, cam orientation axle 5 drives swing arm 7, rotates clockwise simultaneously, relies on body frame locating shaft 2 to locate; When drawing pin 9 to be adjusted to locating hole 61 on cam 6, do curl, now cam 6 rotates counterclockwise, and swing arm 7 remains static, and relies on cam orientation axle 5 to locate.The former is realized by cam-swing-bar mechanism conversion, and the latter changes realization by cam radius.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
