Abstract
The present invention relates to a kind of 3D printing multiple freedom degrees hand-prosthesis the five fingers interlinked mechanism, including the 3rd section of finger, wind spring, palm, the firstth, two sections of fingers, long pin, dump bolts, the 3rd section of finger connects palm and first, two sections of fingers with dump bolt by long pin；Two identical wind springs are respectively installed among two holes of the 3rd section of finger and fixed, and make to do evil through another person finger in active procedure, five fingers remain extended configuration by wind spring.The present invention's does evil through another person the five fingers interlinked mechanism in active procedure, and five fingers are pulled by wrist flex chordae tendineae.Due to installing wind spring at each finger-joint, moment of flexure is produced during digital flexion under a stretching force, allows five fingers to remain extended as all the time, finally realizes the natural stretching, extension of finger.
Description
Technical field
The present invention relates to a kind of 3D printing to be done evil through another person, and machine is interlocked more particularly, to a kind of 3D printing multiple freedom degrees hand-prosthesis the five fingers
Structure, belong to 3D printing and do evil through another person technical field.
Background technology
3D printing multiple freedom degrees hand-prosthesis is the vacation of the purely mechanic driving occurred with the development of 3D printing technique in recent years
Hand.The gearing action of current existing each root finger of 3D printing multiple freedom degrees hand-prosthesis is realized by rubber band.This
Although kind design assembling it is simple and convenient, rubber band is easily affected by the ambient, for example, environment temperature it is higher or
The elasticity of rubber band can be with change when relatively low so that finger movement of doing evil through another person is dumb；Disabled person's wearing is done evil through another person by tree
On article when, branch may hook the rubber band on doing evil through another person, and make troubles.Therefore, it is necessary to which the five fingers done evil through another person are interlocked machine
Structure is designed in inside of doing evil through another person, so that it is safer to do evil through another person, structure is compacter.
The content of the invention
The technology that the present invention is conveniently installed to solve 3D printing mechanical prosthetic hand, used safely, making structure compacter etc.
Problem, and a kind of 3D printing multiple freedom degrees hand-prosthesis the five fingers interlinked mechanism is provided, such a mechanism can cause 3D printing mechanical prosthetic hand
Safety and convenient use in various complex environments.
To achieve the above object, the technical scheme is that：A kind of 3D printing multiple freedom degrees hand-prosthesis the five fingers interlinked mechanism, bag
Include the 3rd section of finger, wind spring, palm, the firstth, two sections of fingers, long pin, dump bolts, the 3rd section of finger by long pin and
Dump bolt connects palm and first, two sections of fingers；Two identical wind springs are respectively installed among two holes of the 3rd section of finger
And it is fixed, make to do evil through another person finger in active procedure, five fingers remain extended configuration by wind spring.
One end of two wind springs is stuck among the bipod of long pin and dump bolt, produce moment of torsion cause palm,
3rd section of finger, the firstth, two sections of fingers are remained point-blank, and original state is restored immediately to after stress.
The beneficial effects of the invention are as follows：
The present invention's does evil through another person the five fingers interlinked mechanism in active procedure, and five fingers are pulled by wrist flex chordae tendineae.By
Wind spring is installed at each finger-joint, produces moment of flexure during digital flexion under a stretching force, allows five fingers to keep stretching all the time
Exhibition state, finally realize the natural stretching, extension of finger.
Brief description of the drawings
Fig. 1 is the 3D printing multiple freedom degrees hand-prosthesis the five fingers interlinked mechanism installation diagram of the present invention；
Fig. 2 is the 3rd section of finger structure schematic diagram；
Fig. 3 is Wind spring structure schematic diagram.
Embodiment
One step explanation is made to the present invention with embodiment below in conjunction with the accompanying drawings：
Such as Fig. 1, shown in 2,3,3D printing multiple freedom degrees hand-prosthesis the five fingers interlinked mechanism of the invention, including the 3rd section of finger 1, wind spring
2nd, palm 3, first, two sections of fingers 4, long pin 5, dump bolt 6.
As shown in figure 1, two identical wind springs 2 are respectively installed among two holes of the 3rd section of finger 1 and fixed, the 3rd
Section finger 1 connects palm 3 and first, two sections of fingers 4 by long pin 5 and dump bolt 6.
As shown in Fig. 2 the 3rd section of finger 1 is connection palm 3 and first, the structure of two sections of fingers 4.The one of two wind springs 2
End is stuck among the bipod of long pin 5 and dump bolt 6, is produced moment of torsion and is caused palm 3, the 3rd section of finger 1, first, two sections
Finger 4 is remained point-blank, and original state is restored immediately to after stress.
As shown in figure 3, wind spring 2, installed in more parts freely done evil through another person on each joint.In finger movement process of doing evil through another person
In, the wind spring 2 on each joint causes five fingers to remain extended as all the time.
