Description
Technical field
The utility model relates to pelvis regulation technology fields, more particularly, to a kind of pelvic movement list based on trapezoidal screw
First width adjustment mechanism.
Background technique
In recent years, aging of population aggravates, and various unsound life styles and traffic accident, industrial injury etc. constantly increase
Add, the patient of walking function obstacle as caused by apoplexy, spinal injury or contingency etc. has become the common group of modern society
Body.To this kind of patient other than using drug and operative treatment, what is relied primarily on is physiotherapy, i.e. progress rehabilitation training, by
Healing robot, which substitutes traditional Physical Therapist, can effectively mitigate the working strength of Physical Therapist and improve the rehabilitation efficiency of patient.
It is connected on the pelvis of human body with lumbar vertebrae, it is the bridge between backbone and lower limb that lower and femur, which constitutes hip joint, body
Weight lower limb are transmitted to by pelvis, the vibration of lower limb is uploaded to backbone also by pelvis, and therefore, it had both been used as the one of backbone
Ring and move, and using hip joint be axis make relative to lower extremity movement.There are six freedom degrees for the pelvic area of normal human, respectively
Left and right, the front and back and upper and lower three of torsion, pitching and three rotational freedoms of inclination and walking process midpelvis at hip joint
The one-movement-freedom-degree in a direction.
Studies have shown that pelvis human body walked, wear the clothes, have a bath, move etc. play in various daily routines it is important
Balanced action will directly influence the motion feature of gait when pelvis generates improper motion profile.According to neural facilitation skill
Art principle, strengthening pelvis control ability can promote the motor function of lower limb, and the training of pelvis can improve the balance of body two sides
Ability accelerates the rehabilitation efficiency of hemiplegic patient.For different patients because fat or thin figure is different, the width at pelvis has larger difference.

Handle can be realized.
The width adjustment mechanism of technology pelvic movement unit disclosed in CN105597278A is by two parallel extensions
Axis simultaneously inwards, stretch out realization, adjust the gap size of gripping block by stirring cam handle to adjust folder when locking
The size of tight block centre bore achievees the purpose that clamp outrigger shaft.And in this way, every time adjust when need to operate four times it is convex
Wheel handle, operating process are relatively complicated；What locking relied on is the frictional force after gripping block deforms with outrigger shaft, if cam hand
Handle pressure it is not tight enough, lead to gripping block deformation not enough, it is possible that frictional force is insufficient, the phenomenon that not tight.
