Wheelchair based on said structure exists that reliability is poor, safety is lower, awkward defect and problem, so cannot well assist the disabled person of lower limb exercise inconvenience to carry out each type games.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wheelchair safe and reliable and easy to use.
For solving the problems of the technologies described above, this utility model provides a kind of wheelchair, comprises chair frame, and described chair frame is provided with swing mechanism, and described swing mechanism comprises the action bars be arranged in chair frame, is provided with roller in the end of described action bars;
Operate described action bars, described roller can be made to be positioned at a primary importance, and described roller is when first position, can play a supporting role to wheelchair toppling over backward;
Operate described action bars, described roller can also be made to be positioned at a second position, and this second position departs from the track that wheelchair is toppled over backward.
The chair frame at the wheelchair backrest back side is provided with rotating action bars; Rotating described action bars can make described roller be positioned at primary importance or be positioned at the second position.
The top of described action bars is provided with operating grip.
Described action bars can in the chair frame being arranged on the wheelchair backrest back side of elastic telescopic, and described action bars elastic telescopic can exercisablely rotate to during the 3rd position, and described action bars elastic telescopic is limited to its rotation during the 4th position.
Described action bars comprises interconnective first action bars and the second action bars, and be formed with angle between described first action bars and the second action bars, described first action bars is rotating to be arranged in described chair frame, and the end of described second action bars is provided with described roller.
The chair frame at the wheelchair backrest back side is provided with action bars passage is installed; Described first action bars runs through described action bars to be installed passage and can rotate in described action bars installation passage.
Described action bars installs channel setting on connector, and described connecting rod is dismountable to be arranged in described chair frame.
Compared with prior art, the beneficial effects of the utility model are: because this utility model is provided with action bars, the end of action bars is provided with roller, and roller can be operated to primary importance or second position, when roller is in first position, safe and reliable supporting role can be played to wheelchair toppling over backward, when roller is in second position, because the second position departs from the track that wheelchair topples over backward, so roller can not hinder wheelchair to carry out toppling over of wide-angle backward or be convenient to the folding of wheelchair, thus the disabled person that can be good at auxiliary lower limb exercise inconvenience carries out all kinds of activity, therefore this utility model is safe and reliable, and it is easy to use.

In figure: chair frame 2, swing mechanism 3, action bars 4, roller 6, installs passage 8, first action bars 40, second action bars 42, flexible member 44, lobe 46, draw-in groove 48, spring shield 50, screw rod 52, operating grip 7.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further details: shown in Figure 1, a kind of wheelchair of the present utility model, comprise chair frame 2, this chair frame 2 is provided with swing mechanism 3, this swing mechanism 3 comprises the action bars 4 be arranged in chair frame 2, is provided with roller 6 in the end of action bars 4; In this utility model, action bars 4 is preferably installed in the chair frame 2 at the wheelchair backrest back side, and it is rotatable, during rotating operation bar 4, roller 6 can be made to be positioned at a primary importance (shown in Figure 2), when roller 6 is in first position, can play a supporting role to wheelchair toppling over backward, thus safe and reliable supporting role can be played to wheelchair toppling over backward; Rotating operation bar 4, roller 6 can also be made to be positioned at a second position (shown in Figure 3), and this second position departs from the track that wheelchair is toppled over backward, and such roller 6 can not hinder wheelchair to carry out toppling over of wide-angle backward or be convenient to the folding of wheelchair.Should be appreciated that the object that the structured flowchart shown in Fig. 1 is only used to example illustrates, instead of the restriction to this utility model scope.In some cases, can change as the case may be.
Shown in Figure 4, action bars 4 comprises interconnective first action bars 40 and the second action bars 42, and be formed with angle between the first action bars 40 and the second action bars 42, dismountable in chair frame 2 connector 10 is installed, this connector 10 is provided with one and passage 8 is installed, first action bars 40 runs through to be installed passage 8 and can rotate in installation passage 8, in the end of the second action bars 42, roller 6 is installed, simultaneously, first action bars 40 is set with preferably helical spring flexible member 44, first action bars 40 is provided with at least one lobe 46, the wall installing passage 8 is provided with the draw-in groove 48 corresponding with lobe 46, can insert in draw-in groove 48 at the effect lower convex portion 46 of flexible member 44, thus the rotation of the first action bars 40 is limited, namely action bars 4 is positioned at the 4th position being limited to rotate, downward pressing first action bars 40, flexible member 44 is compressed, lobe 46 shifts out in draw-in groove 48, at this moment rotatable bar 4, namely action bars 4 is positioned at rotating 3rd position, preferred elastomeric element 44 is partially housed in be installed in passage 8, in addition, first action bars 40 is also set with a spring shield 50, the screw rod 52 that this spring shield 50 is horizontally set is fixed on the first action bars 40, concrete screw rod 50 has run through spring shield 50 and the first action bars 40, flexible member 44 is compressed in spring shield 50 and installs in passage 8 simultaneously, for ease of operation, on the top of action bars 4, operating grip 7 is installed.Concrete pressing operation handle 7, makes action bars 4 move down, lobe 46 is shifted out in draw-in groove 48 first downwards in use, and flexible member 44 is compressed simultaneously, and at this moment rotating operation bar 4 makes roller 6 be positioned at primary importance or the second position; After relief lever 7, action bars 4 can move up lobe 46 can be inserted in draw-in groove 48 under the effect of flexible member 44, thus the rotation of action bars 4 is limited, thus be convenient to user stable, use wheelchair reliably.
