Description
Technical field
This utility model displacement wheelchair belongs to ride instead of walk the wheelchair technical field of usefulness of the people's trip that helps legs and feet inconvenience.
Background technology
What wheelchair commonly used adopted is the four-wheel structure, and two universal front-wheels are positioned at after the pedal, is used for supporting and turning to, and wheel base is very short, rotates flexibly.But because wheelspan is short, the support scope is little, and poor stability only is adapted at indoor and relatively more flat land operations, has big slightly abrupt slope to take wheelchair alone and is absolutely unsafe.Even on the smooth road with footpath on nobody accompany and attend to and also be absolutely unsafe because road general in the middle of high both sides low, wheelchair is not easy control on the road surface that is at a slight tilt.If taking wheelchair wants to tie the shoelace or pick up thing on the ground; The center moves forward to the wheelchair front-wheel during owing to bend over, the danger of turning over before very likely taking place, in addition; Wheelchair often receives that the space is narrow and small brings the restriction of being inconvenient to come in and go out, so common wheelchair only is fit to have the people of certain walking function.
Wheel Wheel-chair commonly used generally is a three-wheel, and wheelspan is near bicycle, and front-wheel is turned to by handlebar, and the problem of riding instead of walk can be resolved safely in the open air, but because wheelspan is big, brings radius of turn practical problem bigger than normal, and car body is big in addition, makes it activity space and scope receives than limitations.
In sum, the width and the length of existing wheelchair or wheel Wheel-chair can not be regulated, and therefore can not satisfy the people who does not have walking function reaches the purpose of taking care of oneself.
Summary of the invention
This utility model overcomes the deficiency that prior art exists, and technical problem to be solved provides a kind of wheelchair that can change wheelspan and wheelbase.
For solving the problems of the technologies described above; Technical scheme that this utility model adopts is: the displacement wheelchair; Comprise the revolver frame that is provided with wheel, the right wheel carrier that is provided with wheel; The structure of revolver frame and right wheel carrier becomes left-right symmetric, and the revolver frame links to each other with the left and right adjusting retaining mechanism with left and right adjusting function on being positioned at wheelchair center link, and right wheel carrier links to each other with the left and right adjusting retaining mechanism with left and right adjusting function on being positioned at wheelchair center link.The structure of left and right adjusting retaining mechanism is: first pull bar and second pull bar are arranged in parallel; Homonymy one end of first pull bar and second pull bar links to each other with wheel carrier; The other end of first pull bar is connected link and has in first sleeve of retaining mechanism, and the other end of second pull bar is in second sleeve that link play the guiding role; Perhaps be arranged in parallel by a pull bar and a screw rod, homonymy one end of pull bar and screw rod links to each other with the revolver frame, and the other end of pull bar is connected link and has in first sleeve of retaining mechanism, and the other end of screw rod is in the screw rod cover of link.Link is also regulated retaining mechanism with main shaft through the front and back of regulatory function before and after having and is linked to each other; The other end of main shaft is connected with pedal and guider with bolt; Guider adopts universal wheel, wheel perhaps is installed below steering handle, and is hinged on the end of main shaft.
The beneficial effect that this utility model compared with prior art has is: the displacement wheelchair utilizes its left and right adjusting retaining mechanism and front and back to regulate retaining mechanism; Can realize the adjusting of wheelspan and wheelbase; Thereby in the small space zone that common wheelchair can't pass in and out, such as the railway carriage door that regular meeting runs into, bathroom door etc.; Can the wheelspan and the wheelbase of displacement wheelchair be adjusted into reduced size, realize freeing in and out; And under the situation of space permission, especially outdoor, wheelspan and wheelbase are adjusted into large-size, make wheelchair have reliable stability.
