Description
Technical field
The invention belongs to care appliances technical fields, and in particular to a kind of nursing adjustable inclination angle back-rest means for chair.
Background technique
For the feeling of pain for alleviating long-term laid-up waist patient the small of the back during permanent sitting, on market today
Occur much automatically adjusting the back-rest means for chair of tilt angle, but they are integrally to carry out inclination angle for back-rest means for chair mostly
The adjustment of degree, and the small of the back different parts of normal person especially old man are often in a plane, so being filled to backrest
When the integral inclined angle set is adjusted, people overlies, and the position of opposed, inwardly directed recess such as waist can be in a vacant state,
Backrest does not play a supportive role to it, this will increase the burden of waist to a certain extent, may further increase waist not
The state of an illness of suitable patient.
Summary of the invention
The technical problem to be solved by the present invention is to solve the above shortcomings of the prior art and to provide one kind to be directed to waist and back
Portion's different parts adjust the stable structure of tilt angle respectively, safe and reliable, easy to operate nursing is filled with adjustable inclination angle backrest
It sets.
To realize the above-mentioned technical purpose, the technical scheme adopted by the invention is as follows:
A kind of nursing adjustable inclination angle back-rest means for chair, including main frame plate, the rear and front end of main frame plate lower surface are just connected to cantilever slab,

Motor movement.
As shown in figure 3, first motor driver, the second motor driver and third motor driver point
The first telescopic rod drive motor, the second telescopic rod drive motor and third telescopic rod drive motor are not driven,
The working principle of the invention: when the small of the back of the user paralysis that needs to lean forward leans against this nursing on adjustable inclination angle back-rest means for chair
When, user's the small of the back first rests on the first adjustable plate 10, the second adjustable plate 11, third adjustable plate 13 and the 4th adjustable plate 14
On, wherein back leans against on the 4th adjustable plate 14, and each position successively leans against the adjusting of third adjustable plate 13, first to waist from bottom to up
On plate 10 and the second adjustable plate 11, power on, control of the controller to each drive motor is set by controller operation panel
Mode is manual operation mode, and operator is by controlling by each motor is driven by key control accordingly on movement controller operation panel
Device processed controls the first telescopic rod drive motor and drives the elongation of the first electric telescopic rod 4, and the first adjustable plate 10 is around the 4th hinged turn
Axis 12 rotates counterclockwise, to be regulated when being fitted on the first adjustable plate 10 to waist corresponding position, and controller control first is stretched
Contracting bar drive motor stops driving, then the tilt angle of 4 stop motion of the first electric telescopic rod, the first adjustable plate 10 is fixed not
Become, during adjusting, when the adjusting of the tilt angle of the first adjustable plate 10 is excessive, controller controls the driving of the first telescopic rod
The first electric telescopic rod of motor drive 4 is shunk, and the first adjustable plate 10 is rotated clockwise, so that inclination angle is finely tuned,
After 10 inclination angle of the first adjustable plate is fixed, controller controls the second telescopic rod drive motor and drives the second electric telescopic rod 5
Elongation, the second adjustable plate 11 rotates counterclockwise around the first hinged shaft 7, to be adjusted to be fitted in the second adjusting to waist corresponding position
When on plate 11, controller, which controls the second telescopic rod drive motor, to be stopped driving, then 5 stop motion of the second electric telescopic rod, the
The tilt angle of two adjustable plates 11 is fixed, and controller controls the second telescopic rod drive motor and the second electric telescopic rod 5 is driven to receive
Contracting, can back finely tune the second excessive adjustable plate 11 of Slope angle adjustment, when the 4th adjustable plate 14 that back is leaned on also needs to improve
When tilt angle, controller controls third telescopic rod drive motor driving third electric telescopic rod 6 and extends, the 4th adjustable plate 14
It is rotated counterclockwise around the second hinged shaft 8, to be regulated when being fitted on the 4th adjustable plate 14 to back, controller controls third
Telescopic rod drive motor stops driving, then 6 stop motion of third electric telescopic rod, the tilt angle of the 4th adjustable plate 14 is fixed
Constant, similarly, third telescopic rod drive motor drives third electric telescopic rod 6 to shrink, can be excessive by Slope angle adjustment
4th adjustable plate 14 is back finely tuned, thus according to user to the small of the back lean on posture comfort level demand, segmentation pointedly into
The adjustment of each adjustable plate gradient of row mitigates the negative of the small of the back so that the upper part of the body of user is fitted on this back-rest means for chair completely
Load and raising comfort level.
When the small of the back of user needs hypsokinesis paralysis to lean against this nursing on adjustable inclination angle back-rest means for chair, user's the small of the back
It first rests on four adjustable plates, powers on, controller is set as manual operation mode by controller operation panel, controller
Controlling the first telescopic rod drive motor drives the first electric telescopic rod 4 to extend, and the first adjustable plate 10 is around the 4th hinged shaft
12 rotate counterclockwise, to be regulated when being fitted on the first adjustable plate 10 to waist lower part, and controller controls the driving of the first telescopic rod
Motor stops driving, makes 4 stop motion of the first electric telescopic rod, then the gradient of the first adjustable plate 10 is fixed, controller control
Making the second telescopic rod drive motor drives the second electric telescopic rod 5 to shrink, and the second adjustable plate 11 is around the first hinged 7 up time of shaft
Needle rotation, to be adjusted when being fitted on the second adjustable plate 11 to waist depression in centre, it is electronic that controller controls the driving of the second telescopic rod
Machine stops driving, then the gradient of the second adjustable plate 11 is fixed, when the 4th adjustable plate 14 that back is leaned on needs to adjust downwards,
Controller controls third telescopic rod drive motor driving third electric telescopic rod 6 and shrinks, and the 4th adjustable plate 14 is hinged around second
Shaft 8 rotates clockwise, and the gradient to the 4th adjustable plate 14 is adjusted to back and can be fitted on the 4th adjustable plate 14, control
Device control third telescopic rod drive motor stop driving, then the gradient of the 4th adjustable plate 14 immobilizes, thus by pair
The concave-convex setting of each adjustable plate, this back-rest means for chair is adjusted makes each position of the small of the back of user can be by required shape to required shape
State paralysis leans against on this back-rest means for chair, meets their comfort level demand；The above operation sequence can also be set by controller operation panel
It is set to automatic operation mode, then controller controls each motor autokinetic movement according to setting program, can greatly mitigate caregiver
The workload of member.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
It should be pointed out that for those skilled in the art, all technical solutions belonged under thinking of the present invention should all regard
For protection scope of the present invention.
