Abstract
The utility model discloses a help lift positioner of road wheel chair handrail, including the flexible riser of bushing type, mount pad and elastically positioned round pin, to install on the mount pad along the slider of the endwise slip of inner tube, the inclined plane butt of establishing drive locating pin withdrawal when the slider removes between slider and the locating pin cooperates. Because the utility model discloses a slider drives locating pin withdrawal, and some driving pieces of user's accessible promote the slider slip like this, for example the ejector pin, the user only need promote the ejector pin, and the ejector pin promotes the slider slip, and the slider passes through the withdrawal of inclined plane drive locating pin, and the user can spur the handrail this moment, ordered about the flexible extremely required height of riser, then unclamped the ejector pin, and the locating pin stretches out the locating hole under the effect of elasticity, highly being fixed up of riser to the realization helps road wheel chair armrest height's regulation. It is thus clear that the utility model relates to a be convenient for very much the operation help lift positioner of road wheel chair handrail.
Description
Technical field
This utility model relates to walking-aided wheelchair technical field, refers 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。
Utility model content
The technical problems to be solved in the utility model 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 this utility model brings: owing to this utility model 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。Visible this utility model 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 this utility model walking-aided wheelchair handrail；
Fig. 2 is the installation diagram of the mounting seat in this utility model, alignment pin and slide block；
Fig. 3 is the explosive view of the mounting seat in this utility model, 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 this utility model, 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。
