Description
Technical field
The utility model relates to traffic mechanical field, particularly relates to a kind of bus safety door.
Background technology
Bus is that present people go on a journey important vehicle, as long as but there is similar fire in one, fall into the accident of waters one class, its dead and wounded large contingent, therefore bus safety problem is more and more paid close attention to, generally present bus all adopts glass or the fully enclosed glass of cliding window, due to bus once the accident that meets accident, the probability of its car door opening is very little, therefore it all can be equipped with safety hammer, glass is broken into pieces as tunnel escape time emergent, break glass into pieces and need certain hour, the commonality of its escape is not strong, often can not play the effect that it helps escape.
Utility model content
Utility model object: the purpose of this utility model is to solve above-mentioned deficiency, a kind of bus safety door is provided, when being in an emergency in car, pull the hinge rod in emergent flip flop equipment mechanism, by tightrope, slide key is extracted from the keyway of chute, chute upper side wall loses the constraint to antifriction-bearing box, outside go-cart door-plate, door panel is around hinge through, so door panel is outwards opened, and opens space and reaches maximum.
In order to solve the problems of the technologies described above, the utility model devises a kind of bus safety door, it is characterized in that, is made up of support frame, rotating mechanism and emergent flip flop equipment:
Described support frame comprises pedestal, top board and four strut bars vertically arranged, and the bottom of described strut bar is welded with pedestal, and its top and roof bolt are connected;
Described rotating mechanism comprises cylinder rocking arm, car door upright column, door-plate, antifriction-bearing box and chute, described car door upright column bottom is held with base via shaft and is connected, its top is connected with cylinder rocker arm, door-plate upper end keeps to the side and locates connection one antifriction-bearing box, chute one side arm has keyway, keyway free-running fit on slide key and chute;
Described emergent flip flop equipment comprises hinge rod, tightrope, slide key and spring, and described hinge rod is coordinated by articulate with right door panel.
Restriction technical scheme of the present utility model is:
Further, aforesaid bus safety door, one end of described tightrope is connected to hinge rod middle position, and forms the laborsaving leverage of homonymy with chain connection point, and the other end of tightrope is connected with slide key upper end.
Aforesaid bus safety door, described door-plate and car door upright column chain connection.
Aforesaid bus safety door, the material of described tightrope is aluminum hawser.
Beneficial effect: the bus safety door designed by the utility model, when being in an emergency in car, push the hinge rod in emergent flip flop equipment mechanism lightly, by tightrope, slide key is extracted from the keyway of chute, chute upper side wall loses the constraint to antifriction-bearing box, outside go-cart door-plate, and door panel is around hinge through, so door panel is outwards opened, and open space and reach maximum; This safety door adopts pure physical construction, structure is simple, in normal driving conditions, can effectively control opening or closing of car door, in case of emergency, passenger can start emergent flip flop equipment quickly and easily, and according to the outside go-cart door of the habitual instinct of people, realizes escape expeditiously and take refuge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail:
embodiment 1
As shown in Figure 1, a kind of bus safety door, is made up of support frame, rotating mechanism and emergent flip flop equipment:
Support frame comprises pedestal 1, top board 2 and four strut bars 3, and strut bar 3 one end is welded with pedestal 1, and the other end and roof bolt link together;
Rotating mechanism comprises cylinder Rocker arm 4, car door upright column 5, door-plate 6, antifriction-bearing box and chute, car door upright column 5 lower end is connected by bearing with pedestal 1, upper end is connected with cylinder rocker arm, door-plate 6 and car door upright column 5 chain connection, door-plate 6 upper end keeps to the side place's connection one antifriction-bearing box, and chute one side arm has keyway, keyway free-running fit on slide key and chute.
Emergent flip flop equipment comprises hinge rod 7, tightrope 8, slide key and spring, together with hinge rod 7 is connected through the hinge with right door panel, one end of tightrope 8 is connected to hinge rod middle position, and forming the laborsaving leverage of homonymy with chain connection point, the other end of tightrope 8 is connected with slide key upper end;
The material of described tightrope 8 is aluminum hawser.
The most crucial part of this device of emergent flip flop equipment room, and the displacement that hinge rod pulls tightrope to produce must be more than or equal to the EFFECTIVE RANGE of slide key, and antifriction-bearing box just can be made to pass through keyway smoothly.
The principle of work of the present embodiment is: when being in an emergency in car, passenger pulls the hinge rod in emergent flip flop equipment mechanism, by tightrope, slide key is extracted from the keyway of chute, chute upper side wall loses the constraint to antifriction-bearing box, outside go-cart door-plate, door panel is around hinge through, so door panel is outwards opened, and open space and reach maximum, thus facilitate the emergency evacuation of passenger and flee from.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
