Above-mentioned traction therapeutic apparatus, the below of its extension table is provided with a damping cylinder 17, damping cylinder is made up of piston cylinder, piston, piston rod, piston cylinder and piston rod are individually fixed on the bed body 14 and Movable bed surface 15 of extension table, back-moving spring 16 1 ends are fixed in a body, and the other end is fixed in Movable bed surface.
For the ease of control, coaxial fixedly oscillating deck 9 is provided with block 12 on the oscillating deck on winding drum, and when oscillating deck arrived desired location, block can contact with the limit switch 8 on being fixed on frame.
For the ease of adopting computer control, must convert the location status of oscillating deck to digital signal, so the limit-switch positions place in this utility model can replace displacement transducer S, the two termination power supplys of described displacement transducer S, its outfan is connected in an A/D change-over circuit, and latter's output connects the data input pin of computer.
Dual-purpose traction therapeutic apparatus according to this utility model is made when the needs lumbar traction, is connected in pull rope on the waist folder, and when the needs cervical traction, only need be connected in pull rope on the neck ring and get final product, and changing-over is very simple.Because cervical traction and lumbar traction shared overlaps main frame, thereby simplified the structure of machine, reduced cost, also reduced breakdown rate.This utility model can also utilize position sensor and A/D change-over circuit except that can controlling by the common relay circuit, convert analog quantity to digital quantity, then carries out computer control to improve the intelligent degree and the reliability of equipment.Adopt small-sized cylinder to make the buffering damped part, be difficult for leaking, cost is low, and is effective, draws comfortablely gently, and patient haves a sense of security.
The utility model is described in further detail below with reference to accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical sketch map of cabinet inside structure;
Fig. 3 is the horizontal sketch map of cabinet inside structure;
Fig. 4 is the extension table section of structure;
Fig. 5 is the control section electrical schematic diagram;
Fig. 6 is the electrical schematic diagram when adopting displacement transducer;
In this utility model, the fixed axil arm of extension table one side has adopted the universal drive shaft structure, and each axil arm 23 is by the formations such as cutting ferrule part of holder 23-1, connecting rod 23-2, universal drive shaft 23-3 and axil arm.Wherein, holder 23-1 is fixed on the body 14, and in insertion holder of connecting rod, the other end connects universal drive shaft, and the latter connects cutting ferrule again.During use, change cutting ferrule over to oxter, the people can be fixed in bed, again the waist clamping is fixed on the waist, be draw operations and get ready.
Relay control figure of the present utility model is shown among Fig. 5, and this circuit is made up of positive contactor ZC, counter-rotating catalyst FC, time relay sj 1, time relay sj 2, travel switch XK1, travel switch XK2, stop button TA, start button QA etc.Wherein, button, catalyst etc. all connects conventional connection and connects, and is connected into rotating control between a pair of normally opened contact FC-1, the ZC-1 of conversing contactor and the motor D.A normally-closed contact that adds the other side in the control coil loop of conversing contactor respectively is to prevent the positive and negative rotation circuit short circuit.The extreme position that travel switch XK1 control is just being changeed, the extreme position of travel switch XK2 control counter-rotating, they are separately fixed on two extreme positions of frame, the normally-closed contact of XK1 inserts the control loop of ZC coil, the normally-closed contact of XK2 inserts the control loop of FC coil, their normally opened contact is the control coil of connect hours relay SJ1, SJ2 respectively, and the latter's time-delay moving together contact SJ-2 is parallel to QA1, and SJ-1 is parallel to QA2.
During operation, start button QA1, ZC gets, connect motor D, beginning is just changeed, and is equivalent to afterburning traction, at this moment, oscillating deck moves with winding drum, arrives the extreme position of setting, XK1 disconnects, ZC outage, motor stall, but because the speed ratio of decelerator is very big, general output revolutions only is several commentaries on classics of per minute, so pull rope can not relax, is equivalent to traction and keeps.At this moment, XK1 has connected time relay sj 1 simultaneously, through default time delay, the moving together contact SJ-1 of SJ1 connects FC, and FC gets electric, the motor counter-rotating, arrive the extreme position of setting, XK2 disconnects, the FC outage, the motor stall, at this moment, because of XK2 has connected time relay sj 2 simultaneously, through default time delay, the moving together contact SJ-2 of SJ2 connects ZC, and ZC gets, motor just changes, and has begun next cyclic process again.
Regulate the delay time of the time relay, just can obtain different traction parameters.
If utilize computer to control, then need analog quantity is converted to digital quantity.Displacement transducer S in this utility model has adopted the WDL-25 type, and it is actually a kind of high-precision potentiometer, its determining positions the height of voltage output.This outfan parallel connection a capacitor C, purpose is suppress to disturb.The A/D change-over circuit adopts ADC0809 (also can adopt other model such as ADC0816 etc. certainly), and this is a kind of 88 passage successive approximation A/D converters, and its digital quantity output is ternary, can directly hang on the microcomputer bus.Because need the data of processing fairly simple, the microcomputer in this utility model can adopt single-chip microcomputer, as 8031,8051,8751 in MCS-51 series or the like.The measured position signalling of pick off is sent into single-chip microcomputer through being converted to digital signal, by computing and logic control, exports away again, and after D/A conversion, amplifying circuit etc. are handled, the rotation of control motor, traction program such as finish traction, keep, loosen.Motor in this extension table has adopted direct current generator, and its speed governing more easily realizes.Because of the circuit comparative maturity of relevant microcomputer control aspect, so repeat no more.
