The lower end of draw-gear 2 Fuel tank 23 is housed, motor 22 is housed on it and hydraulic part 24, one sides are equipped with oil ga(u)ge. This end of draw-gear 2 can insert In the bed body 15. Four universal wheels 20 and foundation bolt 21 are housed below the draw-gear 2.

Bed body 15 is frame-type, and cushion 12 is housed above. One end is cavity, can insert the fuel tank 23 of L-type draw-gear 2, The other end is casing chamber door 16 is housed, and four universal wheels 17 and foundation bolt 18 are housed below.

One side of bed body 15 is equipped with massage machine 8, by motor 25, gear-box 26, column 27 and transverse tube 28 and sleeve pipe 9, Handle 10 and 29, massage head 11 and roller 19 assemble, and its structure is to be driven by motor 25, and be terminal defeated through gear-box 26 Shaft drives the power transmission shaft rotation by spline housing, because eccentric wheel is fixed on the power transmission shaft, spring is housed in it can makes guide pillar Reset, under eccentric effect, guide pillar is made upper and lower rectilinear motion, namely realizes massage head 11 upper and lower repeatedly motions. Revolve Threaded rod in the transduction post, capable of regulating massage head 11 is to the distance of therapentic part. Transverse tube 28 can utilize handle 29 fixing, flexible Adjust. Massage machine 8 can utilize the roller 19 that fills below, and the guide rail of edge bed body 15 moves. Column 27 is rotatable, uses Handle 10 fork-like farm tools used in ancient China are fixed. Bed body 15 1 sides are equipped with emergency button 30. Fixedly carrying an end of 13 hangs on the fixing point 14. The traction waist With being with 7 to hang with segmental support 6, rope 5 ties up to its center, and passes two pulleys 4 and enter in the case of draw-gear 2.

Oil pump 40 among Fig. 3 is equipped with choke valve 34, pressure switch 35, reversal valve 36 and overflow valve 38 by oil pipe 37, The wherein end pushing piston bar 31 that the oil of oil pipe 37 leads to piston 33 moves up or down. Reversal valve 36 is by the reversal valve electromagnetism Iron 1YV and 2YV control. One end of rope 5 ties up to piston rod 31 upper ends.

Display lamp 1HL41 and 2HL42, button 4SB43,3SB44 and 2SB45 are equipped with in the row of going up of operation panel face 1 among Fig. 4, and following row also is equipped with knob switch 1SA46 and 3SA47, button 5SB48 and 1SB49.Time relay 3KT50 also is equipped with in the upper right corner.Pulling force display regulator 1KT51 and time relay 1KT52 are housed below.

L among Fig. 5 ₁, N connects 220 volts of alternating currents.

L among Fig. 6 ₂, N is connected on the L of Fig. 1 ₂On the N contact.

When on and off switch 1SA connection, 1KM adhesive oil pump motor 1M starting, pulling force display regulator 1KP energising can be provided with the treatment time relay 1KI time with that.

The continuous traction circuit course of treatment is by knob button 3SA, time relay 1KT and 2KT, and auxiliary reclay 1K and reversal valve electric magnet 1YV and 2YV (Fig. 6), pulling force display regulator 1KP form.

Contact 3 and 5 when 3SA places " II " position on the circuit; 3 and 6 two connections, 1KI, 1K and 1YV coil electricity are realized " tension ".When tightening force to setting valve, the 1KP effect, its normal opened contact 5,7 disconnects, 1K and 1YV outage, pulling force keeps.When pulling force dropped to lower limit, 1KP moved once more, 1K, and the 1YV energising, pulling force rises, and so do action arrived up to the seance time, and 1KT moves, and the HA sender rings, and normal 8, the 10 connection 2YV of making war of 1KT realize " loosening " simultaneously.When the 2KT setting-up time arrives, its normally closed point 1,2 cuts off the power supply of 1KM, the left alone without help commentaries on classics of oil pump motor 1M.

The gap traction circuit course of treatment is by knob button 3SA, time relay 1KT and 3KT, and auxiliary reclay 1K, 2K, reversal valve electric magnet 1YV and 2YV (Fig. 6), pulling force display regulator 1KP form.

When placing " I " position contact 3 and 4: 3 and 6, connects 3SA, 1KT, and the 3KT coil electricity makes 1K, 2K replace adhesive and release (time is adjustable), 1YV, the 2YV alternate energisation is realized clearance-type " tension " with " loosen ".To setting valve, then 1K, 1YV power supply are cut off in the 1KP action, reach the purpose that keeps certain pulling force at " tension " process such as pulling force.

When hand traction is adjusted, 3SA is placed " 0 " position, press 4SB or 5SB in the circuit, then 1YV or 2YV energising realizes " tension " and " loosen ".

During massage operation, the 3SB that touches the button, A.C. contactor 2KM adhesive, motor 2M rotates, and realizes massage, presses 1SB2KM and discharges, the massage stop.

When patient feels that pulling force is too big, disconnect the emergency button 30 (2SA) that is contained in a body 15 sides.

By above operation, traction and massage can be carried out simultaneously.

The set of devices of pulling force display regulator block chart is contained in the pulling force display regulator 1KP among Fig. 7, its structure by drawing and pressing type pick off DM (Fig. 4) the voltage signal that changes into, send into amplifying unit through filter circuit, form by the linear amplifier of high-precision low-drift and the variable connector of microcomputer automatic zero adjustment.The direct current amplifying unit is amplified to predetermined value to the signal of input, is defeated by A/D converter.

A/D is 41/2 double integration A/D converter of high accuracy, convert to and send into CPU behind the corresponding pulses signal computing is converted to a corresponding binary-coded decimal and a position gated sweep signal through CPU, LED shows measured value by on-off circuit control, and CPU is result of calculation and relatively back control relay output of setting value (SET).
