Specific embodiment
The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
As shown in FIG. 1 to FIG. 7, a kind of servo-actuated armrest mechanism of medical bed, including bedstead 1, backboard 7 and handrail body 6, it is described
Support shaft 10 is arranged in the lower part of the hinged backboard 7 in the top of bedstead 1, backboard 7, by tiltedly propping up between handrail body 6 and support shaft 10
Bar 4 is connected, and handrail body 6 and support shaft 10 are rotatablely connected with oblique fulcrum bar 4, and connection sheet 2 is arranged in the handrail body 6,
Handrail body 6 is hinged on bedstead 1 by connection sheet 2, and the middle part of the support shaft 10 connects push-rod electric machine 8.
The handrail body 6 is made of handrail connection sheet 601, handrail tube 602 and arm supports plate 603, the handrail tube
The top setting arm supports plate 603 of two handrail connection sheets 601, the other end, the oblique branch is respectively set in 602 one end lower part
Bar 4 is located between two handrail connection sheets 601, is articulated and connected between oblique fulcrum bar 4 and handrail connection sheet 601, pacifies at articulated connection
It is noiseless during movement when the setting of bearing, transmission is more steady equipped with bearing；Arm supports plate 603 is used to support human body
Hand.
In order to optimize product structure, the both ends of the support shaft 10, which are separately installed with, to be slidably supported inside and outside support shaft 10
Sliding block 5 is provided with protrusion on the outer wall of the support slipper 5, and support slipper 5 resists handrail body 6, helps described in the present embodiment
Limit plate 3 is set between hand ontology 6 and oblique fulcrum bar 4, and the middle part of the limit plate 3 offers movement slots 9, the limit plate 3
One end and handrail connection sheet 601 connect, and are connected between the movement slots 9 and oblique fulcrum bar 4 by connecting bolt, the connection spiral shell
Bolt can be moved along movement slots 9；By manual rotary handle ontology 6, connection bolt is driven to move along movement slots 9, to handrail body 6
Rotational angle limited, when handrail body 6 is in different angles, handrail body 6 is resisted by support slipper 5, is made
Handrail body 6 no longer moves, user can feel at ease using.
Shifting chute 11 is offered on the side wall of the support slipper 5, passes through connection spiral shell between support slipper 5 and support shaft 10
Bolt is connected, and the connection bolt can be moved along the length direction of shifting chute 11；It is mobile to connect bolt, drives support slipper 5
It is moved along support shaft 10, completes pull operation, while shifting chute 11 plays position-limiting action, avoids support slipper 5 from support shaft 10
Upper disengaging.
The course of work of the utility model is as follows:
The support shaft 10, oblique fulcrum bar 4 and connection sheet 2 of the utility model constitute follower, in use, opening push-rod electric machine
8, when push-rod electric machine 8 extends, backboard 7 is risen, and handrail body 6 is synchronous under the drive of follower at this time rises, and is propped up simultaneously
The angle of support axis 1 changes therewith, and support slipper 5 is driven to change, and makes the protrusion of support slipper 5 towards handrail body 6,
By pull support slipper 5, the bottom surface in the height face and handrail body 6 that support slipper 5 is different is made to contact, resist handrail body 6,
Complete the fixed operation of 6 different angle of handrail body；When push-rod electric machine 8 shorten when, backboard 7 reduce, at this time handrail body 6 with
It is synchronous under the drive of motivation structure to reduce.
The embodiment of the above, the only preferred embodiment of the utility model not limit the utility model
Practical range, therefore all equivalent change or modifications done according to structure, feature and principle described in the utility model patent range,
It should be included in present utility model application the scope of the patents.
