Abstract
The invention discloses an ascending/descending positioning device of a walking-aid wheelchair armrest. The ascending/descending positioning device comprises a casing pipe type stretching-contracting vertical tube, a mounting seat and an elastic positioning pin, the mounting seat is provided with a sliding block which slides in the axial direction of an inner tube, and the sliding block and the positioning pin are arranged in the inclined plane abutting fit mode that the sliding block drives the positioning pin to retreat when the sliding block moves. Due to the fact that the sliding block drives the positioning pin to retreat, a user can push the sliding block to slide through driving pieces, such as an ejector rod, the user only needs to push the ejector rod, the ejector rod pushes the sliding block to slide, the sliding block drives the positioning pin to retreat through an inclined plane, at the moment, the user can pull the armrest to drive the vertical tube to stretch and retreat to the required height, then the ejector rod is loosened, the positioning pin stretches out of positioning holes under the elastic action, and the height of the vertical tube is fixed, so that height of the walking-aid wheelchair armrest is adjusted. The ascending/descending positioning device of the walking-aid wheelchair armrest is quite convenient to operate.
Description
Technical field
The present invention relates to walking-aided wheelchair technical field, refer in particular to the lifting-positioning device of walking-aided wheelchair handrail.
Background technology
Walking-aided wheelchair is generally provided with handrail on the both sides standpipe of vehicle frame, for adapting to the user of different height, standpipe can adopt bushing type to stretch standpipe, namely formed by inner and outer tubes suit, the elastic positioning pin stretching out tube wall is installed in interior pipe, the tube wall of outer tube has the hole, location of some differing heights, realizes the flexible of standpipe by the hole, location of the interspersed differing heights of alignment pin.Flexible being typically all of operation standpipe at present adopts the simple mode pressing alignment pin, direct hands presses alignment pin, alignment pin is made to retract from hole, location, at this moment the inner and outer tubes of standpipe can relative telescopic, after being retractable to desired height, making alignment pin stretch out the hole, location of respective heights, the height of handle riser is fixed up, thus realizing the adjustment of walking-aided wheelchair handrail height.Although this up-down mode simple in construction, but operation inconvenience, during pressing alignment pin, flexible standpipe often damages staff.Therefore, it is necessary to research and develop the lifting-positioning device of a kind of walking-aided wheelchair handrail being easy to operation.
Summary of the invention
The technical problem to be solved in the present invention is to provide the lifting-positioning device of a kind of walking-aided wheelchair handrail being easy to operation.
For solving the technical scheme that above-mentioned technical problem adopts: the lifting-positioning device of a kind of walking-aided wheelchair handrail, include the bushing type being made up of inner and outer tubes flexible standpipe, the mounting seat being arranged in interior pipe and be arranged in mounting seat and stretch out the elastic positioning pin of inner pipe wall, it is characterized in that: described mounting seat is provided with the slide block in axial sliding along interior pipe, be set as when slide block moves between slide block with alignment pin and drive the inclined-plane that alignment pin is retracted to abut cooperation.
On the basis of the above, it is provided with to promote the push rod of skid in described flexible standpipe.
On the basis of the above, described handrail is provided with to promote the button of push rod.
Adopt the beneficial effect that the present invention brings: owing to the present invention adopts slide block to drive alignment pin to retract, such user can promote skid by some actuators, such as push rod, user only need to promote push rod, push rod promotes skid, slide block drives alignment pin to retract by inclined-plane, now user can pull handrail, order about standpipe and be retractable to desired height, then push rod is unclamped, alignment pin stretches out hole, location under the effect of elastic force, and the height of handle riser is fixed up, thus realizing the adjustment of walking-aided wheelchair handrail height.The visible present invention is the lifting-positioning device of a kind of walking-aided wheelchair handrail being highly convenient for operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the lifting-positioning device of walking-aided wheelchair handrail of the present invention；
Fig. 2 is the installation diagram of the mounting seat in the present invention, alignment pin and slide block；
Fig. 3 is the explosive view of the mounting seat in the present invention, alignment pin and slide block.
Detailed description of the invention
As Figure 1-3, a kind of lifting-positioning device of walking-aided wheelchair handrail, include the flexible standpipe of the bushing type being made up of interior pipe 1 and outer tube 2, the mounting seat 3 being arranged in interior pipe 1 and be arranged in mounting seat 3 and stretch out the elastic positioning pin 4 of interior pipe 1 tube wall, handrail 5 is installed on the top of the interior pipe 1 in the present embodiment, and outer tube 2 is fixed with vehicle frame 6.In the present invention, described mounting seat 3 is provided with slide block 7 in axial sliding along interior pipe 1, is set as when slide block 7 moves between slide block 7 with alignment pin 4 and drives the inclined-plane that alignment pin 4 is retracted to abut cooperation.Concrete, inclined-plane in the present embodiment abuts the mode coordinated and is set as: slide block 7 is set as square frame shape, alignment pin 4 is located in the square frame of slide block 7, two inner side frame walls on the moving direction of slide 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 wedge groove 71 form fit.During installation, the wedge groove 71 of two side frames of slide block 7 blocks the wedge tooth 41 of alignment pin 4 both sides, and alignment pin 4 is fitted in mounting seat 3, is provided with compression spring 8, is inserted into interior pipe 1, and fixes mounting seat 3 between alignment pin 4 and mounting seat 3.
For ease of walking-aided wheelchair user operation, the push rod 9 promoting slide block 7 to slide can be provided with in flexible standpipe.The top of push rod 9 can extend handrail 5, so can be provided with to promote the button 10 of push rod 9 on handrail 5.For ease of the reliability of assembling and work, briquetting 11 can be set between push rod 9 and slide block 7.
During adjustable handrail 5 height, user can direct button press 10 on handrail 5, button 10 promotes push rod 9 to move down, and push rod 9 drives slide block 7 to move down, wedge groove 71 orders about wedge tooth 41 and shrinks back, making alignment pin 4 retract, now user can pull handrail 5, makes interior pipe 1 lift to desired height, then release button 10, alignment pin 4 stretches out the hole, location 21 on outer tube 2 under the effect of spring 8, and the height of interior pipe 1 is fixed up, thus realizing the adjustment of walking-aided wheelchair handrail height.
