The content of the invention

The present invention proposes a kind of body part travel mechanism of new adjustable distance, its object is to:Auxiliary patient The movement of body part is carried out, while realizing translation simultaneously under the driving of a set of driving means and lifting the two groups of motions in whereabouts.

Technical solution of the present invention is as follows:

A kind of body part travel mechanism of new adjustable distance, including bed body, base, lower cam chair, column, drive rod, Lever arm and the attachment means for being connected with body part;

In bed body, the lower cam chair is connected to realize relative to base the floor installation by guiding mechanism with base Move up and down;

The base top has the circular hole being engaged with column external cylindrical surface, and the column passes through the circular hole;

The column bottom is provided with disk, and the top of the disk is touched with the bottom connection of the top surface of the base;

Lower cam is provided with the lower cam chair, the disk bottom is provided with overhead cam, the overhead cam and lower cam phase Contact;

The base bottom is additionally provided with the spacing dress for limiting the extreme position that lower cam chair is moved down relative to base Put;

The disk bottom is additionally provided with parallel with column axis and relative to the connecting rod of column eccentric axis;The driving The cylinder body and bed body of bar is hinged, the end of extension bar and connecting rod are hinged to drive column to rotate relative to base;

The column has the through hole for vertically running through, and the lever arm middle part is hinged with column top, and the lower cam chair leads to Cross through the connection member of the through hole and the rear end of lever arm and be connected with activation lever arm relative to column pitch rotation;

The attachment means are installed on the front end of lever arm;

The overhead cam has a boundary curve of downward evagination, and the lower cam has a boundary curve of evagination upwards, it is described on Cam contacts 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 means are suspension ring.

Relative to prior art, the present invention has advantages below:(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 chair, then using the Contact Transmission of overhead cam and lower cam Lever arm pitch rotation is driven, patient can not only be aided in carry out the movement of body part, and using a set of driving of drive rod Device realizes translation and lifts the two groups of motions in whereabouts, has the advantages that simple structure, compact and easy to control;(2) The present invention is provided with the projection for limiting the extreme position that lower cam chair is moved down relative to base, and this projects through pressure Contracting spring one is connected with lower cam chair, it is ensured that remains between overhead cam and lower cam and contacts, high with reliability Advantage.

Description of the drawings

Fig. 1 is the structural representation of the present invention.

Specific embodiment

Describe technical scheme in detail below in conjunction with the accompanying drawings:

Such as Fig. 1, a kind of body part travel mechanism of new adjustable distance, auxiliary is moved when standing up on care bed for patient Move, bend arms, make patient's posture more comfortable.The device mainly includes bed body 1, base 2, lower cam chair 3, column 4, driving Bar 5, lever arm 6 and the attachment means for being connected with body part;

The base 2 be arranged on bed body 1 on, the lower cam chair 3 be connected with base 2 by guiding mechanism with realize relative to Base 2 is moved up and down;The guiding mechanism include the keyway that is opened on base 2 and be arranged on lower cam chair 3 and with The feather key that the keyway is engaged;

The top of the base 2 has the circular hole being engaged with the external cylindrical surface of column 4, and the column 4 passes through the circular hole;

The bottom of the column 4 is provided with disk 4-1, the top of the disk 4-1 and the bottom connection of the top surface of the base 2 Touch;

Be provided with lower cam on the lower cam chair 3, the disk 4-1 bottoms are provided with overhead cam, the overhead cam have to The boundary curve of lower convexity 2-1, the lower cam has the boundary curve of the 2-1 that raises up, the overhead cam and lower cam Boundary curve contacts;

The bottom of the base 2 is additionally provided with for limiting the spacing of the extreme position that lower cam chair 3 is moved down relative to base 2 Device;The stopping means is the raised 2-1 for being arranged at the bottom of base 2, and the raised 2-1 is convex with by compression spring 1 Wheel seat 3 is connected;

The disk 4-1 bottoms are additionally provided with parallel with the axis of column 4 and relative to connecting rod 4-2 of the eccentric axis of column 4; The cylinder body of the drive rod 5 and bed body 1 are hinged, the end of extension bar and connecting rod 4-2 are hinged with drive column 4 relative to Base 2 rotates;
