Specific embodiment
The utility model 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 support frame, support frame include the sub-stent that two sides are arranged in,
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 two sides has been respectively articulated with fixed plate, and seat board is connected between the fixed plate of two sides, and fixed plate is prolonged upwards
Stretching has bar portion, and the upper end in bar portion is hinged with movable part, and the lower end of movable part is detachably connected by switch member with back support rod
It connects, the front support rod is connect by connector with movable part.
When movable part is connect 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 arranged, the setting of inclined or arc；When movable part with
When back support rod separates, front support rod and back support rod close up along articulated shaft rotation, and the bar portion of fixed plate is to back support rod side
It is drawn close to rotation, to realize the folding shrinking of pedestal.
Further, the rear end of the back support rod is connect by connection sheet with movable part, and connection sheet can be opposite respectively
Back support rod, movable part rotation, one end of connector and front support rod are hinged, and the other end of connector and the middle part of connection sheet are cut with scissors
It connects；The upper surface of the back support rod is equipped with U-shaped limited block, and the opening of U-shaped limited block is arranged 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 connect with back support rod,
The lower end of the movable part is protruded into U-shaped limited block, limits position and the front end face of U-shaped block offsets.
Preferably, it is connected with operating parts between two switch members, more preferably, operating parts is arranged in zigzag shape.
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 limited 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 move backward and separate with fixed plate, when separation, can only be come into play part around itself and bar portion hinge
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, in movable part to back spin
When turning, also band follower link is moved backward, and connector drives front support rod to rotate relative to back support rod, plays contractile function.
For convenience of the switch member of two sides is operated simultaneously, here provided with operating parts, the both ends of operating parts respectively with switch
Part connection, by moving up for operating parts, drive two switch members while moving up, at the same make two sides movable part and
Corresponding lower support bar separation.It secondly is in zigzag shape by operating parts setting, convenient for 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 pass through shifting chute stretch out and it is hinged with connection sheet.
Fixing axle can play the position-limiting action to socket ring, and stop collar is avoided to leave movable part；Shifting chute is set simultaneously,
Shifting chute and fixing axle cooperation limit the moving range and displacement of socket ring；Fixing axle is also hinged with connection sheet, plays
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.
It is smaller in view of the lower end surface area of U-shaped limited block, be inconvenient to fix when fixed with back support rod, sole piece is set
Afterwards, back support rod can be fixed on by sole piece, can be used and is bolted, welds.
Further, the connection sheet is V-shaped, arc or the setting of L shape.
The both ends of connector are hinged with the middle part of connection sheet, front support rod respectively, and when pedestal is opened, front support rod is with after
The angled opening of support rod, connector is moved forward by the pulling of front support rod, after the both ends of connection sheet are connected to
Support 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 support rod and back support rod slightly becomes larger, and the middle part of connector and connection sheet is hinged, pulls the middle part of connection sheet forward
It is mobile, after connection sheet is set as V-arrangement, arc and L shape, so that slightly deformation occurs for connection sheet, generate certain elastic force；Work as set
When connecing ring and separating with the U-shaped limited block on back support rod, movable part is quickly separated with U-shaped limited block under the pulling force of connection sheet.
Preferably, movable part includes the column positioned at lower end and interconnecting piece positioned at upper end, one end of interconnecting piece with
Bar portion is hinged.
Composite structure can be used in movable part in the technical program, such as the connecting column and link block being fixedly connected in figure, when
Integral structure can also so be used.Cooperate using column is convenient with socket ring.In view of the convenience of connection, connected by setting
Socket part and bar portion are hinged, and column is avoided to connect difficulty with bar portion.
Further, front rod is connected between the front end of two sides front support rod, between the rear end of two 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, which is arranged, can play the effect for reinforcing entire pedestal, and use is more stable.For convenience of two
Root front support rod is connect with front rod, and the lower end of front rod, which extends back, rear interconnecting piece, and front rod is connected to two
Afterwards between interconnecting piece.
Embodiment 2: a kind of wheelchair, the base structure including embodiment 1, the upper end of base structure are connected with backrest, pedestal
