The column bottom end is provided with disk, and the top of the disk and the bottom connection of the top surface of the pedestal touch；
Lower cam is provided on the lower cam seat, the disk bottom is provided with overhead cam, and the overhead cam is convex under
Wheel is in contact；
The base bottom is additionally provided with the limit for limiting the extreme position that lower cam seat is moved down relative to pedestal
Position device；
The disk bottom is additionally provided with parallel with column axis and relative to the connecting rod of column eccentric axis；It is described
The cylinder body of drive rod is hinged with bed body, the end of extension bar and connecting rod are hinged to drive column to be rotated relative to pedestal；
The column has vertical perforative through-hole, is hinged with column top in the middle part of the lever arm, the lower cam
Seat is turned with activation lever arm relative to column pitching by being connected with the rear end of lever arm across the connecting component of the through-hole
It is dynamic；
The attachment device is installed on the front end of lever arm；
There is the overhead cam boundary curve of downward evagination, the lower cam to have the boundary curve of upward evagination, institute
Overhead cam is stated to be in contact with the boundary curve of lower cam.
As a further improvement on the present invention：The scalable adjustment of length of the lever arm.
As a further improvement on the present invention：The attachment device is hanging ring.
Compared with the existing technology, the present invention has the following advantages：（1）One aspect of the present invention drives column band using drive rod
Dynamic lever arm rotation, on the other hand realizes moving up and down for lower cam seat, then using the Contact Transmission of overhead cam and lower cam
Lever arm pitch rotation is driven, patient can not only be assisted to carry out the movement of body part, and utilize a set of driving of drive rod
Device realizes translation and lifts two groups of movements of falling, and has the advantages that simple in structure, compact and easy to control；（2）
The present invention is equipped with the protrusion for limiting the extreme position that lower cam seat is moved down relative to pedestal, and this projects through pressure
Contracting spring one is connected with lower cam seat, ensure that and remains and contact between overhead cam and lower cam, has reliability high
Advantage.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
Specific implementation mode
The technical solution that the invention will now be described in detail with reference to the accompanying drawings：
Such as Fig. 1, a kind of body part mobile mechanism of Adjustable Range, for patient, when being turned on care bed, auxiliary is moved
It moves, bend arms, keep patient's posture more comfortable.The device mainly includes bed body 1, pedestal 2, lower cam seat 3, column 4, drivings
Bar 5, lever arm 6 and the attachment device for being connected with body part；
The pedestal 2 is mounted in bed body 1, and the lower cam seat 3 is connected with pedestal 2 to realize phase by guiding mechanism
For moving up and down for pedestal 2；The guiding mechanism includes the keyway being opened on pedestal 2 and is set on lower cam seat 3
And with the matched feather key of the keyway；
2 top of the pedestal has passes through the circular hole with the matched circular hole of 4 external cylindrical surface of column, the column 4；
4 bottom end of the column is provided with disk 4-1, the top of the disk 4-1 and the bottom phase of the top surface of the pedestal 2
Contact；
Lower cam is provided on the lower cam seat 3, the bottoms the disk 4-1 are provided with overhead cam, the overhead cam tool
There are the boundary curve of downwardly convex 2-1, the lower cam to have the boundary curve for the 2-1 that raises up, the overhead cam convex under
The boundary curve of wheel is in contact；
2 bottom of the pedestal is additionally provided with the extreme position moved down relative to pedestal 2 for limiting lower cam seat 3
Limiting device；The limiting device is the raised 2-1 for being set to 2 bottom of pedestal, the protrusion 2-1 by compressed spring 1 with
Lower cam seat 3 is connected；
