Abstract
The utility model relates to a chest circumference mechanical arm particularly for nursing traction beds, which comprises two extending crank arms arranged correspondingly and a driving mechanism, wherein each extending crank arm comprises hinges, reset springs, a shrinking rope and a steering sheave. The adjacent sides of two hinges are vertically connected with a plurality of uniformly distributed spring bases, and each base is connected with a reset spring. The shrinking rope penetrates through the axle centers and the bases of all the reset springs. After the lower end of the shrinking ropes pass by the steering sheave, the shrinking rope is in transmission connection with the driving mechanism. The utility model uses a motor to generate dynamic force and the hinges are driven to bend and shrink inward by the shrinking rope so as to achieve the purpose of making human chests mutually bound with bed surfaces. The looseness and the disconnection of the chest circumference mechanical arm can be prevented by using the automatic locking characteristic of a worm wheel worm mechanism. When the motor rotates in a reverse manner, the hinges extent and reset under the action of the recovery elastic force of the reset springs. The utility model has the advantages of simple structure, convenient operation and good consistency of binding force.
Description
Technical field
This utility model relates to a kind of medical rehabilitation facility, specifically is the special-purpose chest measurement mechanical arm of a kind of nursing extension table, is mainly used in the rehabilitation patient is tied up on extension table.
Background technology
To rehabilitations such as patient draw the time, patient need be fixed on the extension table.Present fixed method is to adopt ligature that patient's chest is tied up in bed, and its shortcoming is a very trouble of each operation, and fixed strength is difficult for grasping, and has exerted oneself big and will oppress chest, causes that breast is vexed; Exerted oneself little and slippage easily, all can exert an adverse impact treatment or patient.
Summary of the invention
The purpose of this utility model just provides the special-purpose chest measurement mechanical arm of a kind of nursing extension table, bothers very much to solve the operation that existing manually-operated exists, and fixed strength is difficult for grasping, and exerts oneself improperly all can produce dysgenic problem to treatment or patient.
The technical solution of the utility model is: comprise that two stretching of being oppositely arranged crank arm and driving mechanism, every this stretch to crank arm and comprise hinge, return spring, retraction cord and turn to sheave, vertically be connected with a plurality of uniform spring pedestals two adjacent sides of hinge, between each pedestal, connect a return spring, retraction cord is through the axle center and the pedestal of all return springs, walks around in the lower end of this retraction cord to be in transmission connection with driving mechanism after turning to sheave.
Described driving mechanism comprises motor, transmission and double grooved pulley, and described two lower ends of stretching the retraction cord of cranking arm are separately fixed in two sheaves of double grooved pulley, and the axle of double grooved pulley is in transmission connection by the output shaft of transmission and motor.
Described transmission is a worm-and-wheel gear, and worm gear is connected with the axle of described double grooved pulley, and worm screw is connected with the output shaft of described motor.
Artificial or the motor of this utility model utilization is power, drives the hinge contraction that curves inwardly by retraction cord, thereby reaches the purpose with human chest and the mutual tighten of bed surface, and can utilize the latching characteristics of worm-and-wheel gear to prevent to get loose.When the motor reverse rotation, hinge is stretched out recovery under the effect of the recovery elastic force of return spring.It is simple in structure, and is easy and simple to handle, ties up the power high conformity.
Description of drawings
Fig. 1 is the population structure sketch map of an embodiment of the present utility model;
Fig. 2 is the population structure sketch map of another embodiment of the present utility model.
The specific embodiment
Referring to Fig. 1, this embodiment of this utility model comprise two be oppositely arranged stretch crank arm A and driving mechanism B, every this is stretched the A that cranks arm and comprises hinge 1, return spring 2, retraction cord 5 and turn to sheave 6, vertically be connected with a plurality of uniform spring pedestals 3 in two hinges, 1 an adjacent side, between each pedestal 3, connect a return spring 2, retraction cord 5 is through the axle center and the pedestal 3 of all return springs 2, the upper end of retraction cord 5 is connected with spring pedestal 3 topmost, and the lower end of retraction cord 5 is walked around and turned to sheave 6 backs to be connected with the double grooved pulley 4 of driving mechanism B.
Described driving mechanism B comprises motor 8, transmission 7 (worm-and-wheel gear) and double grooved pulley 4, and the lower end of described retraction cord 5 is separately fixed in two sheaves of double grooved pulley 4, and when direction was rotated, two retraction cord 5 are degrees of tightness simultaneously at double grooved pulley 4.The axle of double grooved pulley 5 is in transmission connection by the output shaft of transmission 7 with motor 8.
Driving mechanism B also can adopt and be suitable for manually-operated structure.
Referring to Fig. 2, two hinge 1 passable lower ends of stretching the A that cranks arm of this embodiment interconnect, and B moves down with driving mechanism.Other structure is identical with a last embodiment.
When implementing this utility model, the width of hinge 1 can suitably increase, and makes the one side constitute groove, and return spring 2 is placed in this groove, prevents that return spring 2 from bending.
This utility model is stretched the A that cranks arm for its two and is installed in the groove above the extension table 9 when using, the motor 8 of driving mechanism B and worm and gear be installed in extension table 9 below, double grooved pulley 4 run through with extension table about.
