Embodiment
The present invention is described in detail below in conjunction with attached drawing.As shown in Figure 1 to Figure 3.
Embodiment 1：A kind of folding base structure, including supporting rack, supporting rack include the sub-stent for being arranged on both sides,
The sub-stent includes front support rod, and front support rod is obliquely installed and upper end is connected with articulated shaft, and is connected with by articulated shaft
The back support rod being inclined to set；
The articulated shaft of both sides has been respectively articulated with fixed plate, and seat board is connected between the fixed plate of both sides, and fixed plate has upwardly extended
Bar portion, the upper end in bar portion are hinged with movable part, and the lower end of movable part is detachably connected by switch member and back support rod, institute
Front support rod is stated to be connected with movable part by connector.
When movable part is connected with back support rod, front support rod and back support rod in angle setting, movable part, fixed plate with
And back support rod setting triangular in shape；When bar portion in fixed plate is specifically set, inclined or arc is set；When movable part with
When back support rod separates, front support rod and back support rod are rotated along articulated shaft to be closed up, and the bar portion of fixed plate is to back support rod side
Drawn close to rotation, so as to fulfill the folding shrinking of pedestal.
Further, the rear end of the back support rod is connected by connection sheet with movable part, and connection sheet can be opposite respectively
Back support rod, movable part rotate, and one end and the front support rod of connector are hinged, and the other end of connector and the middle part of connection sheet are cut with scissors
Connect；The upper surface of the back support rod is equipped with U-shaped limited block, and the opening of U-shaped limited block is set backwards, the switch member include with
The socket ring of movable part lower end socket, the front end for being socketed ring has extended downwardly limiting section, when movable part is connected with back support rod,
The lower end of the movable part is stretched into U-shaped limited block, and spacing position and the front end face of U-shaped block offset.
Preferably, operating parts is connected between two switch members, more preferably, operating parts is set in shape of chinese word Ji.
In the technical program, flexible Application movable part, fixed plate and the back support rod of setting triangular in shape；The triangle
In shape, the upper end of movable part and the bar portion of fixed plate are hinged, and fixed plate is hinged by articulated shaft and back support rod, while activity
Part is connected by the rear end of connection sheet and back support rod, and movable part cannot move upwards substantially, and therefore, movable part is spacing in U-shaped
The cooperation lower limit of block and socket ring is fixed on back support rod；When switch member moves up, the limiting section for being socketed ring leaves U-shaped limit
Position block, movable part can be moved rearwards and be separated with fixed plate, can only come into play part around its hinge with bar portion during separation
Place's back rotation is connect, when movable part is separated with back support rod, fixed plate is also rotated relative to back support rod, is revolved backward in movable part
When turning, also band follower link is moved rearwards, and connector drives front support rod to be rotated relative to back support rod, plays contractile function.
For convenience of the switch member of both sides is operated at the same time, here there is provided operating parts, the both ends of operating parts respectively with switch
Part connects, and by moving up for operating parts, drives two switch members to move up at the same time, at the same cause the movable parts of both sides with
Corresponding lower support bar separation.Secondly it is in shape of chinese word Ji operating parts to be set, easy to operation.
Further, the side of the socket ring is equipped with shifting chute, and the side of the movable part is connected with fixing axle, fixed
One end of axis is stretched out through shifting chute and is hinged with connection sheet.
Fixing axle can play the position-limiting action to being socketed ring, avoid spacing ring from leaving movable part；Shifting chute is set at the same time,
Shifting chute coordinates the moving range and displacement for limiting socket ring with fixing axle；Fixing axle is also hinged with connection sheet, is played
The effect that limitation movable part moves up.
Further, the lower end of the U-shaped limited block is equipped with sole piece, and sole piece is fixedly connected with back support rod.
In view of the lower face area of U-shaped limited block is smaller, be inconvenient to fix when fixing with back support rod, sole piece is set
Afterwards, back support rod can be fixed on by sole piece, can be connected by screw bolts, weld.
Further, the connection sheet is V-shaped, arc or L-shaped are set.
The middle part with connection sheet, front support rod are hinged respectively at the both ends of connector, and when pedestal is opened, front support rod is with after
The angled opening of supporting rod, connector are subject to the pulling of front support rod to move forward, after the both ends of connection sheet are connected to
Supporting rod and movable part；When someone or weight are located on pedestal, the hinged place of front support rod and back support rod is under pressure, preceding
The angle of supporting rod and back support rod somewhat becomes larger, and the middle part of connector and connection sheet is hinged, and pulls the middle part of connection sheet forward
It is mobile, after connection sheet is arranged to V-arrangement, arc and L-shaped so that somewhat deformation occurs for connection sheet, produces certain elastic force；Work as set
When connecing ring and being separated with the U-shaped limited block on back support rod, movable part quickly separates under the pulling force of connection sheet with U-shaped limited block.
Preferably, movable part include positioned at lower end column and the connecting portion positioned at upper end, one end of connecting portion with
Bar portion is hinged.
Movable part in the technical program can use combining structure, such as the connecting pole and contiguous block that are fixedly connected in figure, when
Integrative-structure can also so be used.Coordinate using column is convenient with being socketed ring.In view of the convenience of connection, pass through the company of setting
Socket part is hinged with bar portion, avoids column from being connected difficulty with bar portion.
Further, front rod is connected between the front end of both sides front support rod, between the rear end of both sides back support rod
It is connected with rear connecting rod.Preferably, the front end of front support rod is connected with front wheel, and the rear end of back support rod is connected with rear roller.
Front rod, rear connecting rod is set to play the effect for reinforcing whole pedestal, use is more stablized.For convenience of two
Root front support rod is connected with front rod, and the lower end of front rod, which extends back, rear connecting portion, and front rod is connected to two
Afterwards between connecting portion.
Embodiment 2：A kind of wheelchair, includes the base structure of embodiment 1, and the upper end of base structure is connected with backrest, pedestal
The lower end of structure is connected with roller.
Connection in present specification includes being directly connected to and being indirectly connected with.Above content is only the preferable implementation of the present invention
Example, for those of ordinary skill in the art, according to the thought of the present invention, has in specific embodiments and applications
Change part, this specification content should not be construed as limiting the invention.
