Description
Technical field
The present invention relates to a kind of stretcher of provided with wheels.
Background technology
The lift space of common high residential building is limited, and first-aid stretcher cart is oversize can not enter elevator, cannot hold a load patient's stretcher, makes common high residential building emergency medical service rescue face very large problem.When staying in resident's situation of meeting accident of high residential building and need first aid; often can run into the awkward situation that first-aid stretcher cart can not enter elevator; can not be patient's leukorrhagia hospital's first aid of making a return journey the most fast from high building; delay the quality time giving emergency treatment to a patient, even have many cases that therefore cause patient to get killed.
Summary of the invention
The object of this invention is to provide and a kind ofly thereby bed body can be erected to the stretcher that can enter smoothly elevator with reduced volume.
According to an aspect of the present invention, a kind of stretcher is provided, by bed body and travelling wheel, connected and composed, travelling wheel comprises cradle portion, convergence part and supporting part, supporting part is fixedly connected with bed body, cradle portion comprises forward foot in a step group and rear foot group, and the two ends of convergence part are hinged with one end of forward foot in a step group and rear foot group respectively, and the other end of forward foot in a step group and rear foot group is all hinged with supporting part.
Its beneficial effect is, forward foot in a step group, rear foot group and supporting part are hinged, supporting part can be rotated, again because supporting part is fixedly connected with bed body, therefore this structure can be rotated a body, in actual use, can make it erect to dwindle floor space by rotary bed body, thereby can allow stretcher successfully enter in space-constrained elevator.
In some embodiments, convergence part comprises connecting rod and end, and described end is sheathed on described connecting rod top, and described end is connected by hinging manner with forward foot in a step group, rear foot group respectively.
Its beneficial effect is, end and connecting rod form stretching structure, the connected mode of end and forward foot in a step group, rear foot group is mobilizable hinged, when the rotation of bed body is erected, shrinking convergence part dwindles the angle of forward foot in a step group and rear foot group, can further reduce the floor space of stretcher, and increase the height of stretcher, more convergence is vertical to increase the angle that the bed body highly can make to grow rotates.
In some embodiments, convergence part also comprises clamping piece, and clamping piece is located at the junction of end and connecting rod, and clamping piece is fixed on end or connecting rod.
Its beneficial effect is that clamping piece is used for limiting the extension degree of convergence part stretching structure, thereby is mainly to prevent that connecting rod from be fixed on end or connecting rod cradle portion structural collapse, clamping piece from end disengaging and all can.
In some embodiments, also comprise the first articulated elements, forward foot in a step group, rear foot group and supporting part are equipped with circular hole, and forward foot in a step group, rear foot group and supporting part form chain connection by the first articulated elements through circular hole.
Its beneficial effect is that a kind of articulated manner that forward foot in a step group, rear foot group and supporting part three is formed to articulated structure, makes a body around the first articulated elements, do circular-rotation with supporting part.
In some embodiments, also comprise two the second articulated elements, forward foot in a step group, rear foot group are equipped with blind hole, and end is provided with through hole, and the second articulated elements passes through hole and is placed in blind hole, make end form chain connection with forward foot in a step group, rear foot group respectively.
Its beneficial effect is, a kind of forward foot in a step group, rear foot group of making forms respectively the articulated manner of articulated structure with two ends of convergence part, articulated structure in conjunction with between the stretching structure of convergence part and forward foot in a step group, rear foot group, makes to form foldable structure between forward foot in a step group, rear foot group and convergence part
In some embodiments, bed body is provided with pedal position.
Its beneficial effect is that, when the upset of bed body erects, saved person's foot can step down in pedal position, avoids saved person's landing from bed body.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
Fig. 1～7 have shown a kind of stretcher of the present invention, wherein Fig. 1 and Fig. 2 have shown the occupation mode of stretcher from the side, Fig. 3 and Fig. 4 have intuitively shown the contour structures of stretcher by schematic perspective view, Fig. 5～Fig. 7 has shown the decomposing schematic representation of the connection of the structure that stretcher is inner hiding.
As above, stretcher mainly consists of bed body 1 and travelling wheel 2 two parts, and travelling wheel 2 comprises cradle portion 3, convergence part 4 and supporting part 5 three parts, and bed body 1 is fixedly connected with supporting part 5, and cradle portion 3 comprises forward foot in a step group 6 and rear foot group 7, and convergence part 4 comprises connecting rod 8 and end 9.
It is below the articulated structure of a kind of mode in the present embodiment.
Stretcher is provided with the first articulated elements 10 of column type, and forward foot in a step group 6, rear foot group 7 and supporting part 5 are equipped with circular hole 11, and forward foot in a step group 6, rear foot group 7 and supporting part 5 form chain connection by the first articulated elements 10 through circular hole 11.
Forward foot in a step group 6 and rear foot group 7 is common forms articulated structures with supporting part 5, and respectively with end 9 formation articulated structures.Forward foot in a step group 6, rear foot group 7 and supporting part 5 are hinged, supporting part 5 can be rotated, again because supporting part 5 is fixedly connected with bed body 1, therefore this structure can be rotated a body 1, in actual use, can make it erect to dwindle floor space by rotary bed body 1, thereby can allow stretcher successfully enter in space-constrained elevator.
Stretcher is also provided with the second articulated elements 12 of column type in addition, and forward foot in a step group 6, rear foot group 7 are equipped with blind hole 13, and end 9 is provided with through hole 14, it is placed side by side that convergence part 4 has two connecting rods 8, end 9 is provided with two, is separately positioned on the two ends of connecting rod 8, constitutes a rectangle structure.Two the second articulated elements 12 pass respectively through hole 14 and are placed in blind hole 13, make two ends 9 form chain connections with forward foot in a step group 6, rear foot group 7 respectively.
The two ends of convergence part are hinged with one end of forward foot in a step group and rear foot group respectively, the other end of forward foot in a step group and rear foot group is all hinged with supporting part, articulated structure in conjunction with between the stretching structure of convergence part 4 and forward foot in a step group 6, rear foot group 7, makes to form foldable structure between forward foot in a step group 6, rear foot group 7 and convergence part 4.
Because end 9 and connecting rod 8 form stretching structure, end 9 is mobilizable hinged with the connected mode of forward foot in a step group 6, rear foot group 7 simultaneously, therefore the forward foot in a step group 6 of support and rear foot group 7 also can be rotated with the flexible of convergence part 4, bed body 1 toward erecting while rotating, shrinking convergence part 4 dwindles the angle of forward foot in a step group 6 and rear foot group 7, the one, further reduce the floor space of stretcher, the 2nd, increased the height of stretcher, more convergence is vertical to increase the angle that the bed body 1 that highly can make to grow rotates.
In the present embodiment, bed body 1 is provided with pedal position 16.When 1 upset of bed body erects, saved person's foot can step down in pedal position 16, avoids saved person's landing from bed body 1.
