Abstract
The present invention relates to a liftable armrest of a wheelchair. The armrest is mounted on a frame of the wheelchair by means of two symmetrical support sleeves, and is characterized in that screw rods are coaxially sleeved by the support sleeves mounted between the armrest and the frame; the screw rods are hung in the armrests through T-shaped cross bars; a mounting sleeve is horizontally fixed between the two supporting sleeves; a drive gear is arranged at the middle of the mounting sleeve; the drive gear is rotated by a crank handle by hand cranking; a double-headed bevel gear is arranged coaxially on both sides of the mounting sleeve in a mirror symmetry way, and is provided with driving bevel gears and synchronous bevel gears; and the driving bevel gears are meshed with the drive gear, and the synchronous bevel gears are meshed with the screw rods in the support sleeves. According to the liftable armrest, the crank handle is adopted, and the armrests can synchronously ascend or descend by the crank handle in a way of enabling the double-headed bevel gear to mesh with the screw rods, so that the use is convenient, the operation is easy and the cost is low.
Description
Technical field
The invention belongs to wheelchair field, relate to the handrail of wheelchair, the Liftable armrest of a kind of wheelchair.
Background technology
Wheelchair is the walking aid of patient or people with disability.Existing wheelchair, mostly devise handrail can on turn over
Or dismountable simple designs, does not design elevating function.And some patients, along with the difference in therapy rehabilitation period,
Need to convert the height of wheelchair armrest, create conditions for further rehabilitation.
By retrieval, finding that patent document related with the present patent application is more, close has following four:
1, the liftable wheelchair of handrail (CN102429783A).Relate to a kind of wheelchair.Including chair frame, seat, backrest and hands
Handle, chair wheel, handrail, foot-operated, it is characterized in that: below handrail, be linked with long handrail tube, the two ends of long handrail tube are fixed with forward and backward
Guide rod, forward and backward guide rod periphery is socketed with the forward and backward conduit that lower end is fixed in chair frame, is connected with upper and lower between forward and backward conduit
Reinforcement, on front guide rod, inner side is provided with several hole, location being arranged above and below, and is designed with and is matched with hole, location inside dummy pipe upper end
Elevation and subsidence regulating device, on dummy pipe, outer middle side part is provided with short handrail tube.Elevation and subsidence regulating device is by regulating handle, and rear end screw thread is even
Be connected to regulate handle, front end is matched with the bullet pin positioning hole, is socketed on the regulation block of bullet pin periphery, is fixed in dummy pipe
Side, be matched with bullet pin and regulation block regulation pipe, be socketed on bullet pin periphery stage clip constitute.Through on probation, load-bearing is steadily reliable,
Lift adjustment is convenient and swift, and manufacturing cost is less, and cost function is than substantially reducing.
2, the Liftable armrest (CN201578469U) of a kind of wheel chair with multiple adjustable parts, is mainly pulled with protecting by handrail transverse tube
Connecting tube, cushions support pipe are intubated by handrail and connect as one, and protect and pull the upper and lower side of connecting tube and connect fixing locking bar respectively
Constitute with lower fixing locking bar.The most reasonable in design, fashionable, and be the matching component of wheel chair with multiple adjustable parts.
3, the wheelchair armrest structure (CN204909883U) of a kind of liftable and slide anteroposterior, including wheelchair armrest, at wheel
The center of armrest of seat (8) connects lifting unit, also includes sliding unit connected vertically with lifting unit, holds up at wheelchair
Add lifting unit and lifting unit on hand, enable wheelchair armrest to lift or slide anteroposterior, it is adaptable to the use of different heights
Person uses and various demand stance adjustment.
4, the lifting-positioning device (CN205322721U) of a kind of walking-aided wheelchair handrail, include bushing type stretch standpipe,
Mounting seat and elastic positioning pin, mounting seat is provided with the slide block in axial sliding along inner tube, between slide block and alignment pin
The inclined-plane being set as when slide block moves driving alignment pin to retract abuts cooperation.Owing to this utility model uses slide block to drive location
Pin is retracted, and such user can promote slide block to slide by some actuators, such as push rod, and user only need to promote push rod, push rod
Promotion slide block slides, and slide block drives alignment pin to retract by inclined-plane, and now user can pull handrail, orders about standpipe and is retractable to required
Highly, then unclamping push rod, alignment pin stretches out hole, location under the effect of elastic force, and the height of handle riser is fixed up, thus real
The regulation of existing walking-aided wheelchair handrail height.
First two of above-mentioned four patent documents, applicant thinks that its structure is complex, with the present patent application
Technical scheme differs.
Summary of the invention
In place of it is an object of the invention to overcome the deficiencies in the prior art, it is provided that the Liftable armrest of a kind of wheelchair, this is held up
Hands lifting is simple, practical, quick, with low cost.
The present invention solves technical problem and be the technical scheme is that
The Liftable armrest of a kind of wheelchair, the frame of described wheelchair installs handrail by two symmetrical support sets, its
It is characterised by: coaxial inner sleeve one leading screw in the support set installed between described handrail and frame, this leading screw passes through T in handrail
Word cross bar is mounted in handrail；Between two support sets, laterally it is fixedly mounted with an installation set, a driving tooth is installed in the middle part of this installation set
Wheel, this driving gear passes through the hand rotation of crank；In installing set, both sides specular is coaxially installed with drive bevel gear and together
The double end bevel gear of step bevel gear, wherein drive bevel gear mesh driving gear, and the silk in synchronous cone gear elongate support set
Thick stick.
And, frame is fixed with swivel nut, this swivel nut engagement leading screw.
The present invention with good effect is a little:
1, this handrail use rocking bar, this rocking bar by two-way bevel gear engagement leading screw by the way of make handrail synchronize rise or
Decline, easy to use, easily operate, with low cost.
2, this handrail design science, is skillfully constructed, the theory of mechanics of abundant bevel gear engagement, makes easily, and patient can
With easy manipulation.
Accompanying drawing explanation
Fig. 1 is the structural front view of the present invention；
Fig. 2 is the structure enlarged diagram (broken section) of the armrest portion of Fig. 1.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following example are descriptive
, it not determinate, it is impossible to limit protection scope of the present invention with this.
The Liftable armrest of a kind of wheelchair, the frame 6 of described wheelchair 8 installs handrail by two symmetrical support sets 2
