lower floor's stretcher chamber storehouse 7 and somely can coordinate fixing snap close 29 with stretcher, safety in utilization can be improved further like this,
Operation principle of the present invention is as follows:
In an initial condition, the piston rod of hydraulic power unit 8 hydraulic control cylinder 9 stretches out, by quadric chain, the face, stretcher chamber storehouse, upper strata 5 of upper strata stretcher chamber is horizontal, and locating rod 27 is just in time inserted in the spacing hole of spacing orifice plate 28, thus the upper strata stretcher chamber being positioned at horizontal level is fixed, face, stretcher chamber storehouse, upper strata 5 just in time sticks gag lever post 10 and is in the state not pulling out upper strata stretcher chamber base 4 due to latch hook 13 before bottom it, face, lower floor's stretcher chamber storehouse 7 also just in time sticks gag lever post 10 and is in the state not pulling out lower floor's stretcher chamber base 6 due to latch hook 13 before bottom it,
When stretcher is positioned over face 5, stretcher chamber storehouse, upper strata by needs, first rotational drive arm 26, locating rod 27 is departed from from the spacing hole of spacing orifice plate 28, and then retracted by the piston rod of hydraulic power unit 8 hydraulic control cylinder 9, face, stretcher chamber storehouse, upper strata 5 can be made to be in slant setting state by quadric chain; Then the pull bar 20 bottom face, stretcher chamber storehouse, upper strata 5 is pulled forward, in the process that pull bar 20 pulls forward, pull bar 20 can synchronously drive front rod 17 and rear connecting rod 18 to move forward, before front rod 17 drives again, latch hook 13 rotates backward and decontrols gag lever post 10, now, with regard to energy outwards face, stretcher chamber storehouse, pull upper strata 5; After face, stretcher chamber storehouse, upper strata 5 is drawn out, rear latch hook 16 bottom face, stretcher chamber storehouse, upper strata 5 just in time sticks gag lever post 10, then releasing lever 20, pull bar 20 can move backward under the effect of the rearward pulling force of elastic parts, in the process of pull bar 20 movement backward, pull bar 20 moves after synchronously driving rear connecting rod 18, and after rear connecting rod 18 synchronously drives again, latch hook 16 rotates forward and blocks gag lever post 10, thus is fixed by face 5, stretcher chamber storehouse, the upper strata locking of extraction; Then stretcher is slipped into face, stretcher chamber storehouse, upper strata 5, the snap close 29 of its upper surface is passed through by stretcher fastening in face, stretcher chamber storehouse, upper strata 5; And then stretched out by the piston rod of hydraulic power unit 8 hydraulic control cylinder 9, by the original state that quadric chain makes the face, stretcher chamber storehouse, upper strata 5 of upper strata stretcher chamber be horizontal, then pull bar 20 is pulled forward, in the process that pull bar 20 pulls forward, pull bar 20 can synchronously drive front rod 17 and rear connecting rod 18 to move forward, after rear connecting rod 18 synchronously drives, latch hook 16 rotates back to and decontrols gag lever post 10, just the face, stretcher chamber storehouse, upper strata 5 that stretcher is housed can be pushed back upper strata stretcher chamber base 4; After the face, stretcher chamber storehouse, upper strata 5 that stretcher is housed is pushed back upper strata stretcher chamber base 4, the front latch hook 13 bottom face, stretcher chamber storehouse, upper strata 5 just in time sticks gag lever post 10, thus is fixed by face 5, stretcher chamber storehouse, the upper strata locking pushed back; And then rotational drive arm 26, make locating rod 27 just in time be inserted in the spacing hole of spacing orifice plate 28; By aforesaid operations, namely complete action stretcher being loaded into face, stretcher chamber storehouse, upper strata 5; In actual use, when hydraulic power unit 8 damage or other reasons cause hydraulic power unit 8 to lose efficacy and uncontrollable hydraulic cylinder 9 piston rod flexible time, can start to unload and compress switch 30, unloading compresses switch 30 can lay down oil pressure in hydraulic cylinder 9, make the piston rod energy free-extension of hydraulic cylinder 9, now, can be manually downward-sloping or be moved upward to horizontal level backward forward by the face, stretcher chamber storehouse, upper strata 5 of upper strata stretcher chamber by hand-pushing handle 22;
When stretcher is positioned over lower floor's stretcher chamber face 7, storehouse by needs, then the pull bar 20 bottom face, lower floor's stretcher chamber storehouse 7 is pulled forward, in the process that pull bar 20 pulls forward, pull bar 20 can synchronously drive front rod 17 and rear connecting rod 18 to move forward, before front rod 17 drives again, latch hook 13 rotates backward and decontrols gag lever post 10, now, with regard to energy outwards face, pull lower floor stretcher chamber storehouse 7; After face, lower floor's stretcher chamber storehouse 7 is drawn out, rear latch hook 16 bottom face, lower floor's stretcher chamber storehouse 7 just in time sticks gag lever post 10, then releasing lever 20, pull bar 20 can move backward under the effect of the rearward pulling force of elastic parts, in the process of pull bar 20 movement backward, pull bar 20 moves after synchronously driving rear connecting rod 18, and after rear connecting rod 18 synchronously drives again, latch hook 16 rotates forward and blocks gag lever post 10, thus is fixed by face 7, the lower floor's stretcher chamber storehouse locking of extraction; Then stretcher is slipped into face, lower floor's stretcher chamber storehouse 7, the snap close 29 of its upper surface is passed through by stretcher fastening in face, lower floor's stretcher chamber storehouse 7, then pull bar 20 is pulled forward again, in the process that pull bar 20 pulls forward, pull bar 20 can synchronously drive front rod 17 and rear connecting rod 18 to move forward, after rear connecting rod 18 synchronously drives, latch hook 16 rotates back to and decontrols gag lever post 10, just the face, lower floor's stretcher chamber storehouse 7 that stretcher is housed can be pushed back lower floor's stretcher chamber base 6; After the face, lower floor's stretcher chamber storehouse 7 that stretcher is housed is pushed back lower floor's stretcher chamber base 6, the front latch hook 13 bottom face, lower floor's stretcher chamber storehouse 7 just in time sticks gag lever post 10, thus is fixed by face 7, the lower floor's stretcher chamber storehouse locking pushed back; By aforesaid operations, namely complete action stretcher being loaded into face, lower floor's stretcher chamber storehouse 7;
Advantage of the present invention is: (1) is by the inclination and the reset that coordinate the upper strata stretcher chamber storehouse face that can freely control upper strata stretcher chamber of hydraulic cylinder with quadric chain, in actual use, medical personnel only need first to be faced down in stretcher chamber storehouse, upper strata inclination by hydraulic cylinder, and then stretcher slips into downward-sloping face, stretcher chamber storehouse, upper strata, then face, stretcher chamber storehouse, upper strata is made to be reset to horizontal level by hydraulic cylinder again, namely complete the loading of stretcher, operate very laborsaving convenience; (2) face, upper strata stretcher chamber storehouse and face, lower floor's stretcher chamber storehouse all can freely pull out, and face, stretcher chamber storehouse can be connected with ambulance better, and convenient medical personnel load and unload stretcher.
