The preferred spring scale of the present embodiment.
The flexible setting of extensible member 187 enables second pulley to adjust about 179, when the highland of supporting pad 141 occurs
During change, adjust extensible member 187 and cause the height of second pulley 179 that stretching assembly 171 is varied so that together with supporting pad 141
Supporting pad 141 can be coordinated, the athletic of different condition is met and used.And the setting of above-mentioned each slide rail and sliding part can
Relative distance between the company of regulation stretching assembly 171, to meet the demand of the telemechanical person of different shoulder breadths.
Further, as shown in Fig. 2 two ends and human arm pair of the supporting pad 141 near the edge of upper limbs training institution 170
Answer and be each provided with position a touching switch 144, warning lamp 194, two touching switch are provided with upper limbs training institution 170
144 circuit is connected with the circuit of warning lamp 194.When training athlete push and pull bar 173 raise one's hand it is too low, ancon contact touching
Switch 144 then switches on power, and warning lamp 194 is shinny to be trained with alerting sportsman's specification.
Freestyle swimming dry season training device 100 uses process：On supporting pad 141, hip joint is located at rocking bar 112 to sportsman's prostrate
With the junction of support mechanism 140, leg is positioned on rocking bar 112, and foot is fixed by leg fixture 119, the bottom on both legs
It is dynamic, drive rocking bar 112 to swing by leg fixture 119, connecting rod 113 is pushed or above carries, and drive flying wheel 114 to rotate, even
Connecing the rotating shaft 128 of two flying wheels 114 can ensure the synchronous axial system of two flying wheel 114, and then ensure the alternating synchronization liter of two rocking bar 112
Drop, flying wheel 114 rotates the frictional force produced and friction belt 136 between and is converted into the resistance of motion that both legs swing up and down, and trains
Improve athletic lower limbs strength.When the crank-motion on one end flying wheel 114 to upper extreme position and connecting rod 113 are conllinear,
Crank and rocker mechanism is in upper dead center position, completes once to go up swaying legs action, when the crank-motion on other end flying wheel 114 is arrived
When lower limit position is conllinear with connecting rod 113, crank and rocker mechanism is in lower dead point position, completes once to descend swaying legs action, inertia
114 rotations in the presence of self inertia power of wheel, can overcome lower dead point position on crank and rocker mechanism, both legs to exchange upper and lower
Swing, be just respectively completed once upper and lower swaying legs action, so repeatedly, imitating swimming exercise can train the athletic lower limb of raising
Strength.Player hand handle 173, does extensional motion, and when both hands pull handle 173, connecting rope 175 follows handle 173 1
Motion is played, connecting rope 175 drives first pulley 177 and second pulley 179 to move and pull the second elastic resistance device 174 together,
Produce the resistance of motion；After pulling terminates, both hands return arm and promote handle 173, pull the first elastic resistance device 172, produce motion resistance
Power, complete once draw push it is dynamic.So repeatedly, imitate swimming to strike motion, can train and improve athletic upper limbs force, more
The elastic resistance device of different resistances is changed, the size of the resistance of motion is can adjust, different training effects are produced.Return in sportsman's both hands
During arm promotes handle 173, note lifting elbow, if lift elbow is not in place, ancon contact touching switch 144 connects warning lamp 194
Power supply, warning lamp 194 is shinny, proposes warning.Motion is caused because the opposite end of handle 173 is respectively connected with elastic resistance device
Member simulates action that sportsman strikes in water with arm so that sportsman's arm is taken exercise in drawing process.Resistance is adjusted
Section mechanism 130 can adjust the resistance of motion that both legs swing up and down；And the width that the adjustable in length both legs for changing crank swing up and down
Degree.Exert oneself the upper and lower swing of both legs in trainer, while both hands draw, push dynamic, support as trainer's upper limb body and lower limb body
The strength of the waist and belly of effect is also obtained taking exercise and improved.
The preferred embodiment of the present invention is the foregoing is only, the present invention is not limited to, for this area
For technical staff, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made it is any
Modification, equivalent, improvement etc., should be included within the scope of the present invention.
