Detailed description of the invention:

With reference to Fig. 1, Fig. 2 and Fig. 3, the massager core of chain drive walking, comprises core upper cover 1, movement drain pan 2, motor 3, worm gear variator 4, gear transmission chain and massage assembly 5; Motor 3, worm gear variator 4 and gear transmission chain are installed between movement drain pan 2 and core upper cover 1, form a massager core entirety: movement drain pan 2 slides by chute 21 and is positioned on base plate 9, more particularly on the guide rail 91 on base plate 9, can move reciprocatingly by opposed bottom 9, this base plate 9 is provided with spacing translot 92, base plate 9 edge is provided with positive stop 93, can block on the protruding rail 22 at movement drain pan 2 edge, massager core is slided and is embedded on base plate 9.

Described gear transmission chain comprises massage teeth endless chain 6 and walking gear chain 7, massage teeth endless chain 6 primary pinion A61 engages with worm gear in-line gears, the A axle of final-stage gear A62 63 passes core upper cover 1, end winding support has massage assembly 5, and in this legend, massage assembly is massage rotating disk 51; In the primary pinion B71 of walking gear chain 7 and massage teeth endless chain 6, the B axle 73 of a gears meshing, final-stage gear B72 is fixed with through on the end of movement drain pan 2 sprocket wheel 74 of walking, this walking sprocket wheel 74 and be arranged on movement drain pan 2 between driven sprocket 75 to be provided with chain 76, a chain shaft is convexly equipped with drive pin 77, this drive pin 77 inserts in the spacing translot 92 of base plate, cater to drive pin 77 on chain by described spacing translot 92 to turn back the change of position, that is the rotation in walking sprocket wheel 74 1 directions, can realize moving back and forth.

For this reason, the walking primary pinion B71 of wheel chain 7 or massage teeth endless chain 6 with this primary pinion B71 meshed gears are provided with unilateral bearing 78, walking gear chain 7 is made to only have a direction of rotation to be driven by this unilateral bearing 78, that is, a direction of rotation of motor 3 just can drive walking, and another direction of rotation of motor, massager core is slack, and this can solve the needs of massager core fixed point massage.

Be arranged with an axle bed swing arm 76 between the B axle 73 of the final-stage gear B in described walking gear chain 7 and prime gear shaft, to ensure the reliability engaged, avoid because arc axle bed 11 gap between core upper cover 1 and movement drain pan 2 exists and skid.

In more than illustrating, massage teeth endless chain 6 is extensible multistage, and gear shaft in position installs massage assembly 5, realizes two or more massage assembly 5 work compound, improves massage efficiency; This is just for single head output motor.

This example motor has double end output shaft, the first axle driven wheel driving-chain, drives massage teeth endless chain 6 and walking gear chain 7, second beam warp worm gear variator 4 speed change, the worm-wheel shaft 41 of worm gear variator is directly positioned between core upper cover 1 and movement drain pan 2 by bearing 42, an eccentric 8 is fixed with respectively at worm-wheel shaft 41 two ends, a draft arm 81 is arranged with outside eccentric 8, draft arm 81 other end is hinged on a bottom of patting 52, this beating 52 one-tenth dumbbell shapeds, middle part is positioned at core upper cover 1 surface by axle, motor 3 drives this beating 52 two to rise and fall and pats action, owing to adopting worm gear one-level speed change, therefore speed is relatively very fast, somewhat stiff sense during massage, for this reason, this draft arm 81 is designed to binodal structure, there is a transition arm 82, by transition arm 82 with to pat 52 hinged, transition arm 82 provides cushioning effect.
