Description of the drawings
Fig. 1 is the structure diagram for the articulation mechanism that the utility model embodiment provides.
Specific embodiment
Below by specific embodiment and with reference to attached drawing, the utility model is further described in detail.
It please refers to Fig.1, the utility model embodiment provides a kind of articulation mechanism of the medical model of human body, including arm branch
Support 10, resistance set 20, shoulder axis 30, spring 40, adjusting nut 50 and fixed mechanism 60.
Arm supporting bracket 10 be used for fixed-analog arm, arm supporting bracket 10 be usually U-shaped structure, two of U-shaped structure
Side wall is both provided with grip block 101, and grip block 101 is fixed on by screw 102 on arm supporting bracket 10, is cured for trapping human
With the simulation arm of model.
Shoulder axis 30 is fixedly linked with arm supporting bracket 10, and shoulder axis 30 usually passes through screw 302 with arm supporting bracket 10
It is fixedly linked.One end that shoulder axis 30 is connected with arm supporting bracket 10 has resistance area.In order to improve fixed stability, shoulder
The bottom of axis 30 can be provided with tabular pedestal 301, and shoulder axis 30 can be fixed on hand by tabular pedestal 301 by screw 302
On arm supporting rack 10.The one side that tabular pedestal 301 and arm supporting bracket 10 are away from each other is resistance area, that is, tabular pedestal 301
Top surface be resistance area.
Resistance set 20 is set in shoulder axis 30, and one end end face of resistance set 20 fits with resistance area.Spring 40 is arranged
In shoulder axis 30.Adjusting nut 50 and 30 thread fitting of shoulder axis.Spring 40 is arranged on the another of adjusting nut 50 and resistance set 20
Between the end face of one end, for applying the active force that its end face is made to be closely attached on resistance area to resistance set 20.Fixed mechanism 60 is for solid
