[0025] The utility model provides an emergency stretcher 100.
[0026] See also Figure 1-Figure 3In one embodiment of the present invention, the emergency stretcher 100 includes a first stretcher frame 10, a second stretcher frame 20 and a fixing structure. The first stretcher frame 10 is provided with a connecting block 30 on the frame, and the connecting block 30 can be rotated on the first stretcher frame 10. The second stretcher frame 20 is provided with a connecting pin 31. The second stretcher frame 20 is connected to the connecting block 30 via the connecting pin 31, and the second stretcher frame 20 can be rotated on the connecting block 30. The fixing structure includes an elastic member 40 and a fixing member 41. The fixing member 41 is located within the frame of the first stretcher frame 10. The elastic member 40 is located within the frame of the first stretcher frame 10 and abuts against the elastic member 40. The fixing member 41 is partially located within the frame of the second stretcher frame 20, splicing the first stretcher frame 10 and the second stretcher frame 20 together. When the fixing member 41 is detached from the second stretcher frame 20, the second stretcher frame 20 can be rotated on the connecting block 30 to be folded.
[0027] In this embodiment, a first receiving groove 11 is defined in the frame of the first stretcher frame 10, and a second receiving groove 21 is defined on the frame of the second stretcher frame 20. The two ends of the fixing member 41 are respectively located in the first receiving groove 11 and the second receiving groove 21 to splice the first stretcher frame 10 and the second stretcher frame 20 together. It can be understood that when the fixing member 41 extends from the first receiving groove 11 and extends into the second receiving groove 21, the second stretcher frame 20 uses the fixing member 41 as a fulcrum and is flush with the first stretcher frame 10, and unfolds to form a stretcher bed.
[0028] In one embodiment of the present invention, the fixing member 41 includes a cylinder 43 and a boss 42. The cylinder 43 is located within the frame of the first stretcher frame 10. The boss 42 is provided on the arc surface of the cylinder 43 and is exposed on the upper surface of the frame of the first stretcher frame 10. A sliding groove 13 is provided on the frame of the first stretcher frame 10. The boss 42 passes through the sliding groove 13 and is exposed on the upper surface of the frame of the first stretcher frame 10. The cylinder 43 can be controlled to move within the frame of the first stretcher frame 10 through the boss 42.
[0029] In this embodiment, the elastic member 40 is a spring, but is not limited thereto. The cylinder 43 is retracted into the first stretcher frame 10 through the boss 42, so that the cylinder 43 can be separated from the second stretcher frame 20. At this time, the second stretcher frame 20 can be rotated and folded.
[0030] In one embodiment of the present invention, a through hole 12 is further provided in the frame of the first stretcher frame 10, and the through hole 12 is communicated with the first receiving groove 11. The cylinder 43 includes a large column 44 and a small column 45. The large column 44 is located in the first receiving groove 11, and the small column 45 passes through the through hole 12 and extends into the second stretcher frame 20.
[0031] In this embodiment, the inner diameter of the first receiving groove 11 is larger than the inner diameter of the through hole 12. Correspondingly, the outer diameter of the large column 44 is larger than the outer diameter of the small column 45. The small column 45 extends into the second receiving groove 21. Therefore, the inner diameter of the second receiving groove 21 is consistent with the outer diameter of the small column 45. While ensuring that the small column 45 can smoothly extend into the second receiving groove 21, the gap between the small column 45 and the second receiving groove 21 is reduced to reduce shaking.
[0032] In one embodiment of the present invention, a positioning platform 50 is provided on the first stretcher frame 10. The positioning platform 50 is located on one side of the connecting block 30. A locking member 51 is provided on the positioning platform 50. A slot 32 is provided on the connecting block 30. The locking member 51 extends into the slot 32 to position the connecting block 30.
[0033] In this embodiment, when the locking member 51 is engaged with the slot 32, the angle of the connecting block 30 is parallel to the frame of the first stretcher frame 10 and cannot be rotated. When the locking member 51 is disengaged from the slot 32, the connecting block 30 can be rotated to facilitate folding and reduce interference between the first stretcher frame 10 and the second stretcher frame 20.
[0034] Among them, the locking part 51 includes a connecting part 52 and a locking part 53, and the locking part 53 is sleeved on the connecting part 52. The connecting part 52 can be a bolt. A positioning nut 54 is provided on the connecting part 52 to position the locking part 52 so that it can be maintained in one position. When the connecting part 52 is fixedly connected to the rotating positioning platform 50, the locking part 53 will not rotate with the connecting part 52 and can be more conveniently inserted into the slot 32.
[0035] In one embodiment of the present invention, a support plate 60 is provided on the first stretcher frame 10 and the second stretcher frame 20 respectively. A bottom plate 61 is provided on the support plate 60. A safety belt 62 is provided on the bottom plate 61. When a patient lies flat on the bottom plate 61, the safety belt 62 can be used to stabilize the patient and improve the stability of movement.
[0036] The first stretcher frame 10 and the second stretcher frame 20 are both provided with moving wheels 90. The moving wheels 90 can be flipped and can be flipped to be parallel to the first stretcher frame 10 and the second stretcher frame 20 when the first stretcher frame 10 and the second stretcher frame 20 are folded, so as to facilitate storage. When in use, they are flipped down and perpendicular to the ground. The moving wheels 90 can be fixed by punching holes in the first stretcher frame 10 and the second stretcher frame 20, and inserting pins through the moving wheels 90 into the corresponding holes for fixed positioning.
[0037] The second stretcher frame 20 is also provided with a hand guard 70, on which the patient's hands can be placed, making it easier for the doctor to perform other operations such as diagnosing the condition. The first stretcher frame 10 and the second stretcher frame 20 are each provided with a stretcher pole 80, which is convenient for the operator to move and lift.
[0038] Working principle: When it is needed, first insert the locking member 51 into the slot 32 to fix the connecting block 30, then operate the boss 42 to retract the fixing member 41 into the first stretcher frame 10, and then rotate the second stretcher frame 20 to be flush with the first stretcher frame 10, so that the first receiving groove 11 is aligned with the second receiving groove 21, and then release the boss 42. Under the elastic force of the elastic member 40, the fixing member 41 extends into the second receiving groove 21, and the first stretcher frame 10 and the second stretcher frame 20 are aligned. The stretcher frames 20 are spliced and unfolded to form a stretcher bed; when it needs to be stored, the boss 42 is manipulated again to retract the fixing member 41 into the first stretcher frame 10. When the fixing member 41 is completely separated from the second stretcher frame 20, the angle of the second stretcher frame 20 is rotated, and then the locking member 51 is separated from the slot 32, so that the connecting block 30 can also rotate. Finally, the moving wheel 90 is flipped over to be flush with the first stretcher frame 10 and the second stretcher frame 20, and the folding is completed; after folding, it can be easily carried and transported.
[0039] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
