Abstract
The present invention discloses a kind of lifting-positioning device of walking-aided wheelchair handrail, include bushing type flexible standpipe, mounting seat and elastic positioning pin, sliding block in axial sliding along inner tube is installed, the inclined-plane for being set as driving alignment pin to retract when sliding block moves between sliding block and alignment pin abuts cooperation in mounting seat.Alignment pin is driven to retract using sliding block due to of the invention, so user can promote sliding block to slide by some actuators, for example push rod, user need to only promote push rod, push rod promotes sliding block to slide, sliding block drives alignment pin to retract by inclined-plane, and now user can pull handrail, drive standpipe to be retractable to required height, then push rod is unclamped, alignment pin stretches out positioning hole in the presence of elastic force, and the height of handle riser is fixed up, so as to realize the regulation of walking-aided wheelchair handrail height.It can be seen that the present invention is a kind of lifting-positioning device for the walking-aided wheelchair handrail for being highly convenient for operation.
Description
Technical field
The present invention relates to walking-aided wheelchair technical field, the lifting-positioning device of walking-aided wheelchair handrail is referred in particular to.
Background technology
Walking-aided wheelchair is generally provided with handrail on the both sides standpipe of vehicle frame, to adapt to the user of different heights, standpipe meeting
Stretched standpipe using bushing type, i.e., formed by inner and outer tubes suit, the elastic positioning pin for stretching out tube wall is installed, outside in inner tube
The positioning hole of some different heights is provided with the tube wall of pipe, the positioning hole of different height is interted by alignment pin to realize standpipe
It is flexible.What operation standpipe was flexible at present is typically all by the way of simply pressing alignment pin, directly presses alignment pin with hand, makes
Alignment pin is retracted from positioning hole, at this moment the inner and outer tubes of standpipe can relative telescopic, be retractable to needed for after height, make alignment pin
The positioning hole of respective heights is stretched out, the height of handle riser is fixed up, so as to realize the regulation of walking-aided wheelchair handrail height.It is this
Up-down mode is although simple in construction, but operates inconvenience, and when pressing alignment pin, flexible standpipe often damages human hand.Therefore,
It is necessary to research and develop a kind of lifting-positioning device of walking-aided wheelchair handrail easy to operation.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of lifting-positioning device of walking-aided wheelchair handrail easy to operation.
Technical scheme used by solve above-mentioned technical problem：A kind of lifting-positioning device of walking-aided wheelchair handrail, bag
Include the bushing type being made up of inner and outer tubes flexible standpipe, the mounting seat in inner tube and in mounting seat
And stretch out the elastic positioning pin of inner pipe wall, it is characterised in that：It is provided with the mounting seat along inner tube in axial sliding
Sliding block, the inclined-plane for being set as driving alignment pin to retract when sliding block moves between sliding block and alignment pin abut cooperation.
On the basis of the above, it is provided with the flexible standpipe to promote the push rod that sliding block slides.
On the basis of the above, it is provided with to promote the button of push rod on the handrail.
Using beneficial effect caused by the present invention：Drive alignment pin to retract using sliding block due to of the invention, so use
Family can promote sliding block to slide by some actuators, such as push rod, and user need to only promote push rod, and push rod promotes sliding block to slide,
Sliding block drives alignment pin to retract by inclined-plane, and now user can pull handrail, drive standpipe to be retractable to required height, then unclamp
Push rod, alignment pin stretch out positioning hole in the presence of elastic force, and the height of handle riser is fixed up, so as to realize walking-aided wheelchair handrail
The regulation of height.It can be seen that the present invention is a kind of lifting-positioning device for the walking-aided wheelchair handrail for being highly convenient for operation.
Brief description of the drawings
Fig. 1 is the structural representation of the lifting-positioning device of walking-aided wheelchair handrail of the present invention；
Fig. 2 is mounting seat in the present invention, the installation diagram of alignment pin and sliding block；
Fig. 3 is mounting seat in the present invention, the explosive view of alignment pin and sliding block.
Embodiment
As Figure 1-3, a kind of lifting-positioning device of walking-aided wheelchair handrail, includes what is be made up of inner tube 1 and outer tube 2
Bushing type stretch standpipe, the mounting seat 3 in inner tube 1 and in mounting seat 3 and stretch out the tube wall of inner tube 1 bullet
Property alignment pin 4, the top installation handrail 5 of the inner tube 1 in the present embodiment, outer tube 2 fixes with vehicle frame 6.In the present invention, the peace
Sliding block 7 in axial sliding along inner tube 1 are installed on dress seat 3, are set as driving when sliding block 7 moves between sliding block 7 and alignment pin 4
The inclined-plane that dynamic alignment pin 4 is retracted, which abuts, to be coordinated.It is set as specifically, the inclined-plane in the present embodiment abuts the mode coordinated：Sliding block 7 is set
Into box shape, alignment pin 4 is located in the square frame of sliding block 7, and two inner side frame walls on the moving direction of sliding block 7 form triangle wedge groove
71, the direction that wedge point stretches out towards alignment pin 4, the both sides of alignment pin 4 form the triangle wedge tooth 41 with the form fit of wedge groove 71.
During installation, the wedge groove 71 of two side frames of sliding block 7 blocks the wedge tooth 41 of the both sides of alignment pin 4, and alignment pin 4 is fitted in mounting seat 3,
Compression spring 8 is provided between alignment pin 4 and mounting seat 3, is inserted into inner tube 1, and fix mounting seat 3.
Operate, can be provided with flexible standpipe to promote the push rod 9 that sliding block 7 slides for ease of walking-aided wheelchair user.Top
The top of bar 9 can extend handrail 5, can so be provided with to promote the button 10 of push rod 9 on handrail 5.For ease of assembling and
The reliability of work, briquetting 11 can be set between push rod 9 and sliding block 7.
During 5 height of adjustable handrail, user button press 10, button 10 can promote push rod 9 to move down directly on handrail 5, push up
Bar 9 drives sliding block 7 to move down, and wedge groove 71 drives wedge tooth 41 to be shunk back, and alignment pin 4 is retracted, and now user can pull handrail 5,
Inner tube 1 is set to lift to required height, then release button 10, the positioning that alignment pin 4 is stretched out on outer tube 2 in the presence of spring 8
Hole 21, the height of inner tube 1 is fixed up, so as to realize the regulation of walking-aided wheelchair handrail height.
