Summary of the invention
The present invention seeks to: provide a kind of simple in structure, easy to use, act freely with the matching used folding seat of ambulance.
A kind of ambulance of the present invention is used folding seat, comprises the medicated cushion and the backrest that can fold, said ambulance with folding seat also comprise can so that ambulance with folding seat guide rail that goes up and down and the stopping means that can control lifting position.
Preferably, said guide rail is two, is positioned at said backrest behind.
Preferably, on the said guide rail fixing hole is arranged, said stopping means comprises the steady pin and the jacking block that can stretch; Said steady pin is positioned on the backrest, and said jacking block is positioned on the medicated cushion, when turning down medicated cushion; Jacking block pushes steady pin on the medicated cushion; Make the pin head of steady pin stretch out, and extend in the solid hole on the guide rail that seat is positioned.
Preferably, said medicated cushion and backrest adopt to have and spacingly are connected with the rotating mechanism of positioning function, and said rotating mechanism comprises outer plate; Interior sheet, axle, locking ball and spacer pin; Said outer plate has place kick groove and stopper slot, and said locking ball and spacer pin are positioned on the sheet.
Preferably, said ambulance also comprises the handrail of extension type with folding seat, and the handrail of said extension type comprises expansion link, support bar and handrail, and said expansion link one end links to each other with backrest through rotating shaft, and the other end links to each other with handrail; Said support bar one end links to each other with handrail through rotating shaft, and the other end links to each other with medicated cushion through rotating shaft.
Preferably, said expansion link is the damping telescopic bar.
Preferably, said ambulance also comprises seat belt with folding seat, and said seat belt links to each other with backrest.
Preferably, said guide rail is between the upper strata of ambulance litter frame and lower floor's litter frame.
Advantage of the present invention is: seat design becomes deployable and the form of gathering in, during expansion, takies lower floor litter frame position, abdicates the position after the gathering and uses for lower floor's litter frame.Simple in structure, easy to use, can settle the prone position and the sitting posture sick and wounded, do not take too much interior space again.

Wherein: 1 backrest; 2 handrails; 3 expansion links; 4 seat belt; 5 support bars; 6 medicated cushions; 7 rotating mechanisms; 8 outer plates; Sheet in 9; 10; 11 locking balls; 12 spacer pins; 13 steady pins; 14 guide rails; 15 jacking blocks; 16 spacer pins; 17 limited blocks; 18 guide rails.
The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, ambulance shown in Figure 6 is used folding seat, comprises medicated cushion that can fold 6 and backrest 1, guide rail 18 is positioned at backrest 1 behind, seat not the time spent can descend, do not interfere the use of upper strata litter frame.Seat can raise when using, and just can make highly to meet and take requirement, and seat goes up and down to lean on lifting rail, and lifting position is by limited block control, spacer pin locking.On the guide rail 18 fixing hole is arranged, steady pin 13 is positioned on the backrest 1, and jacking block 15 is positioned on the medicated cushion 6; When turning down medicated cushion 6, jacking block 15 pushes steady pin 13 on the medicated cushion, makes the pin head of steady pin stretch out; And extend in the solid hole on the guide rail 18, seat is positioned, and can support human body weight and can not fall; Consider the seat vibration damping, be laid on the stretcher after medicated cushion is turned down that the power on the seat is born by stretcher basically.Adopt rotating mechanism 7 to connect between medicated cushion 6 and the backrest 1, rotating mechanism 7 comprises outer plate 8, interior sheet 9; Axle 10; Locking ball 11 and spacer pin 12, outer plate 8 has place kick groove and stopper slot, and locking ball 11 is positioned on the sheet 9 with spacer pin 12; Medicated cushion is adjacent to backrest at ordinary times each other, makes the locus minimum.When using, medicated cushion is turned down, the rotating mechanism realization of this moment through being associated on medicated cushion and the backrest.Rotating mechanism has two functions: the one, and spacing, the 2nd, the location.Limit function realizes through spacer pin prescribed limit travel in stopper slot, positioning function be on the interior sheet locking ball on outer plate in the ball groove location realize.Expansion link 3 one ends link to each other with backrest 1 through rotating shaft, and the other end links to each other with handrail 2, and support bar 5 one ends link to each other with handrail 2 through rotating shaft, and the other end links to each other with medicated cushion 6 through rotating shaft.Expansion link can center on and be placed in rotating shaft rotation on the backrest, and can be flexible together with the handrail that is fixed on the expansion link.Support bar is supporting armrests down below, also can rotate around the rotating shaft that is placed on the medicated cushion.Backrest, medicated cushion, expansion link, support bar form closed frame, constitute firm supporting construction.When medicated cushion rolled up, support bar rotated and drives the expansion link purse up, and upwards changeed.After medicated cushion was translated into the position, handrail was also drawn in.When turning down medicated cushion, support bar changes down, and expansion link is changeed down pull out, and limit shaft qualification in the expansion link no longer continues to stretch out when moving to, and handrail is stabilized in deployed condition.Because outside support bar was tilted to, under external force, handrail is inwardly indentation not.During the handrail upset damping should be arranged, in case rock after drawing in.Damping function is in rotating shaft on the nylon jacket or use the damping telescopic bar.Consider it is the folding seat that ambulance is used, the present invention also is provided with seat belt 4, and seat belt 4 links to each other with backrest.
Above embodiment is merely the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
