7 one end is provided with supporting shaft hole 7-1 and multiple keyway 7-2, and multiple keyway 7-2 are uniformly arranged in supporting shaft hole 7-1, described
Shaft 6-2 is slidably connected in supporting shaft hole 7-1, and multiple key rib 6-3 are slidably connected at respectively in multiple keyway 7-2；Outward
Hand-held pole 6-1 is pulled, so that key rib 6-3 be made to separate with keyway 7-2, and then supporting leg 7 can be made to rotate around shaft 6-2；It is described
7 clearance fit of supporting leg is in the supporting leg mounting groove between cross-beam body 5-1 and supporting rack 5-2；Under the action of arguing for the sake of arguing spring,
Key rib 6-3 is slid into again in keyway 7-2, and the fixation of supporting leg 7 is realized with this；It, can be in order to when 7 horizontality of supporting leg
The carrying of medical stretcher, while medical stretcher can be reduced when disaster relief supplies are transported and be taken up space.
A kind of medical stretcher of the invention, its working principle is that: in use, patient is placed on carrying cloth 2, pass through four
A argue for the sake of arguing 6 lifts two crossbeams 5, and two crossbeams 5 pass through two spring columns 3 and four 4 elasticity liftings of arc spring arculaes
Rectangular frame 1, and then cloth 2 will be carried and lifted together together with the patient on carrying cloth 2；Make in the gravity of patient and rectangular frame 1
Under, rear and front end argue for the sake of arguing 6 height change when, two spring columns 3 remain vertical state, pass through arc spring arculae
4 and crossbeam 5 maintain crossbeam 5 vertical with rectangular frame 1, and then ensure the horizontality of rectangular frame 1；Be conducive in earthquake relief work
Etc. under adverse circumstances, maintain patient to lie low, vibration when reducing lift fortune sufferer and rock, to effectively avoid due to rocking and shaking
Move the problem of aggravating when causing on patient；6 are argued for the sake of arguing by outside pull, can rotate supporting leg 7；It, can when supporting leg 7 is horizontal
To lay flat on the ground rectangular frame 1 and carrying cloth 2, it is convenient for sending patient's lift to carrying cloth 2 with this；And four supports
When leg 7 is each rotated to vertical state, two crossbeams 5 can be supported by four supporting legs 7, at this time two spring columns
3 and four arc spring arculaes 4 play the role of bradyseism, rectangular frame 1 and carrying cloth 2 form horizontal hammock, can be with this
Interim treatment hospital bed is provided under contingency condition for patient；The distance between two stringer 1-3 are greater than the width of carrying cloth 2, into
And when patient lies on carrying cloth 2, the middle-end of carrying cloth 2 is hung low downwards, lies in the centre bit of carrying cloth 2 convenient for patient with this
It sets, prevents patient from dropping from carrying cloth 2 with this, while being conducive to rectangular frame 1 and keeping horizontality；Holding is pulled outward
Bar 6-1 so that key rib 6-3 be made to separate with keyway 7-2, and then can be such that supporting leg 7 rotates around shaft 6-2；In spring of arguing for the sake of arguing
Under effect, key rib 6-3 is slid into again in keyway 7-2, and the fixation of supporting leg 7 is realized with this；When 7 horizontality of supporting leg,
Can be in order to the carrying of medical stretcher, while medical stretcher can be reduced when disaster relief supplies are transported and be taken up space.
Certainly, above description is not limitation of the present invention, and the present invention is also not limited to the example above, the art
The variations, modifications, additions or substitutions that those of ordinary skill is made within the essential scope of the present invention also belong to guarantor of the invention
Protect range.
