Detailed description of the invention

One, critical piece

As it is shown in figure 1, this utility model includes side frame 1, link 2, road wheel 3.

1, side frame.

As shown in Fig. 2, Fig. 3, Fig. 4, Fig. 6, described side frame 1 is positioned at the both sides of wheel-chair, square-shaped, be two parallel And it being provided with short tube between the single frame perpendicular, connection is fixed at cross bar two ends, its length of tube is more than the thickness of road wheel 3, montant 12 upper end The mouth of pipe is equipped with band and intubates the handrail 14 of 141, and handrail can move up and down and position fixing, and armrest rear end is provided with opening hole clipping 142, the back of the body Bar 24 lower end is rotationally connected through hole clipping with side frame upper end cross bar 11, when handrail 14 is fitted with cross tube 11, and back of the body bar and upper horizontal stroke The connecting shaft of bar is on hole clipping, and with handrail 14 side by side, after handrail carries, back of the body bar is vertical, carries on the back cloth 241 liang for back of the body bar 24 horizontal positioned Side cloth set set is through on back of the body bar, and back of the body cloth passes from handrail hole clipping opening part.

As shown in Figure 6, described side frame back montant 12 or below cross bar 11 are provided with shaft seat 15 that is fixing or that slide, turn Axle bed is mainly used in being rotationally connected with forward and backward crotch rear end both sides rotating shaft 35, and sliding shaft seat can be sleeve structure, and its effect is Adjust wheel crotch rotating shaft position, to convert the distance that wheel stretches out.

As it is shown in figure 9, sleeve pipe 171 set being rotationally connected with pedal 18 is through montant 12 lower end, side frame front, pedal The most rotatable side frame of putting into, the semicircle gear pipe 181 of its plate lower end of horizontal positioned is stuck on casing wall, and foot can be placed on its plate On.

Side plate 13 can be hung outside side frame, can be respectively as seat board, backboard.

2, road wheel.

As shown in Figure 5, Figure 6, road wheel 3 includes front forked frame 31, front-wheel 32, rear crotch 33, trailing wheel 34, described front forked frame Being wider than front-wheel width between fork arm, its termination is fixing connects semi-circular arc plate 311, and its plate rear end is provided with elastic snib 312, described before Wheel is omnirange runner, and tube 321 upper end of wheel is provided with rotating shaft 35, can be rotationally connected with fork arm upper half arc plate upper end, tube Lower end is provided with fixture block 322 with holes, can fix mutually with the elastic snib of arc plate rear end, and both sides, front forked frame rear end are provided with rotating shaft 35, can Be rotationally connected with the fixing or sliding shaft seat 15 on side frame sheer pole, the snib 36 on both sides, front forked frame stage casing, can with under side frame Before end, frame corner card hole 16 fixes.

The fork arm termination, front end of described rear crotch 33 is rotationally connected trailing wheel both sides spindle nose, and wheel can be walked the most backward, left and right Can not rotate, rear fork stage casing, rear end are respectively arranged with snib, rotating shaft, can with fixing on side frame sheer pole or rear montant or Sliding shaft seat 15 is rotationally connected.

As shown in Figure 8, Figure 9, road wheel is arranged on balladeur train 17, and balladeur train periphery fixed connecting sleeve 171, its sleeve pipe wears On side frame montant 12, and sliding up and down in side frame and fix, rear crotch 33 is rotationally connected with balladeur train 17 back segment base, back vent Frame level can fix or vertically place, the tube of front-wheel 32 is vertically fixedly connected on balladeur train front end, front-wheel base with fixed Trailing wheel flushes.

3, link.

As shown in Figure 1 and Figure 2, being provided with link 2 between two side frames 1, it includes support bar 21 and folding rod 22, support bar Least one set, its two are waited stock central rotational to connect, and bar lower end is connected with same side frame sheer pole 11, connects and has two kinds of structures, One is fixing connection, but such structure easily causes the following distance of side frame after folding less than top distance, and two is to be rotationally connected, The sleeve pipe 171 that i.e. support bar lower end and set are through on sheer pole is rotationally connected, or is connected with fixed rotating shaft 35, and such side frame folds Rear distance up and down can be equal；Post upper is fixing with seat bar 23 to be connected, and seat cloth set is through between the seat bar of both sides, and seat cloth is the longest Spending the width sat with people and arrange, inside side frame, epimere is provided with grab 28, and when wheel-chair launches, seat bar 24 is buckled on grab, wheel When Wheel-chair converts into, support bar merges to be holded up, and exceeds side frame and be used as handle, as use side plate 13 when seat board, backboard, two side frames Being rotationally connected the lateral folding bar 22 of Intermediate Gray baffle plate hinge 221, position is located at and flushes place with grab 28, the length that its bar launches Corresponding with the length of put side plate 13, side frame lower end or connection folding rod are with stable support body.

Two, road wheel and the annexation of side frame.

In general, time in the built-in side frame of road wheel, its volume is minimum, during expansion, after the trailing wheel center of circle should move on to side frame At inferior horn, front-wheel moves at side frame forward lower comer, and trailing wheel and front-wheel keep certain distance optimal, and such wheel-chair just can stably be difficult to Rollover, therefore, case above to be considered during design.In the built-in side frame of road wheel or move to the mode of both sides, side frame lower end include with Lower two kinds, one is that crotch rotates storing, and one is that balladeur train moves up and down storing, illustrates separately below.

1, crotch rotates and puts.

As shown in Figure 6, Figure 7, its structure is, described side frame 1 is double-rod frame, front forked frame rear end rotating shaft 35 and side frame sheer pole 11 leading portion shaft seats 15 are rotationally connected, and semi-circular arc plate 311 upper end of front forked frame front end rotates even with front-wheel tube 321 upper end Connecing, the fixture block with holes 322 of tube lower end separates with the elastic snib 312 after arc plate, and front forked frame 31 is holded up front-wheel 32 lowering and existed In side frame 1；Or the snib 36 on its both sides, bar stage casing of front forked frame horizontal positioned fixes in side frame forward lower comer hole clipping 16, front-wheel tube The fixture block with holes 322 of 321 lower ends fixes with the elastic snib 36 on front forked frame top, front wheel landing, rear crotch 33 rear end rotating shaft 35 It is rotationally connected with the shaft seat 15 of side frame sheer pole back segment or rear montant stage casing, and rises and falls for the center of circle with junction point, on rear crotch Turn and hold up in trailing wheel is built in side frame 1 and fix, horizontal positioned or be disposed vertically, the snib on its both sides, rear crotch stage casing and side frame The hole clipping of posterior angle fixes, and trailing wheel lands.

The distance that front-wheel, trailing wheel expose below side frame to ground is equal, parallel shape at side frame cross bar and ground.

2, balladeur train slides and puts.

As shown in Figure 8, Figure 9, described side frame 1 is parallel double rods frame, and the sleeve pipe 171 of balladeur train is socketed with side frame montant, balladeur train Slide up and down and position fixing, the fixing front-wheel tube that connects in balladeur train front end, front-wheel all-direction rotation and be perpendicular to ground, after balladeur train Section is rotationally connected with rear crotch rear end rotating shaft 35 below, balladeur train moves in road wheel is placed in side frame by side frame top and fixes, balladeur train Being snapped down at the bottom of side frame the snib 36 outside it and fix in hole clipping at the bottom of frame, rear crotch back rotation is to the most horizontal and both sides, stage casing Snib fixes mutually with balladeur train rear end hole clipping, and the partial-length that front-wheel, trailing wheel expose below side frame is equal.
