[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] The following description, in conjunction with the accompanying drawings, describes a multi-functional rescue stretcher for fire and rescue according to an embodiment of the present invention.

[0028] As shown in Figures 1-5, the multi-functional rescue stretcher for fire rescue according to the present invention may include a padding layer 1, a support plate 2, a lifting rod 3, an outer frame 4, a fixing mechanism 5, and a protective layer extension rod 6.

[0029] The padding layer 1 is embedded in the top of the support plate 2, the lifting rods 3 are symmetrically arranged on both sides of the support plate 2, the outer frame 4 is set under the support plate 2, and a notch structure is provided on either side of the outer frame 4. The fixing mechanism 5 is set under the support plate 2 and close to the notch structure.

[0030] The protective layer release rod 6 is located under the support plate 2 and away from the notch structure. The protective layer release rod 6 has rods 7 at both ends, and the protective layer is wrapped around the rods 7. The protective layer release rod 6 is connected to the two ends of the protective layer release rod 6 and is equipped with fixing components 8. The fixing components 8 include fixing blocks 9, grooves 10, limiting tubes 11 and driving tubes 12.

[0031] The fixing block 9 is located on the inner side of the outer frame 4, the groove 10 is embedded in the fixing block 9, the limiting tube 11 is located on the inner side of the groove 10, the rod body 7 structure is inserted into the groove 10, and the driving tube 12 passes through the rod body 7 structure and is inserted into the limiting tube 11.

[0032] Specifically, the protective layer on the protective layer release rod 6 is pulled out, passing over the padding layer 1, separating the pressure roller 17 and the extrusion strip 18, and inserting the protective layer into the pressure roller 17 to complete the laying of the protective layer. Afterwards, the staff rescues the injured person using a stretcher. After each injured person is transported, the staff pulls the protective layer located on one side of the pressure roller 17, pulling the protective layer above the padding layer 1 until this part of the protective layer is completely pulled between the pressure roller 17 and the extrusion strip 18. At the same time, the protective layer is pulled, and the protective layer release rod 6 rotates synchronously to release the protective layer. Depending on the situation, the staff can choose to cut off the contaminated protective layer with tools to avoid affecting the staff's use of the stretcher. This process is repeated, and after each injured person is transported, the protective layer is changed by pulling it to avoid using the same protective layer for multiple injured persons.

[0033] When it is necessary to replace the protective layer release rod 6, the drive motor 14 drives the drive screw 15 to rotate. The drive screw 15 controls the drive tube 12 to move away from the rod body 7. The drive rod moves out of the rod body 7. Then, the staff removes the protective layer release rod 6 and puts in the new protective layer release rod 6. The end of the rod body 7 is sleeved on the limit slide rail 16 and slides into the groove 10. Then, the drive motor 14 controls the drive tube 12 to insert into the rod body 7 and into the limit tube 11, completing the replacement of the protective layer release rod 6.

[0034] In one embodiment of the present invention, as shown in FIG4, the fixing block 9 is provided with a control cavity 13, the control cavity 13 is provided with a drive motor 14, the end of the drive motor 14 is fixedly connected with a drive screw 15, the drive screw 15 is screwed into the drive tube 12, and the drive tube 12 is provided with an internal thread structure that matches the outer surface of the drive screw 15.

[0035] It should be noted that the drive motor 14 drives the drive screw 15 to rotate, and the drive screw 15 controls the drive tube 12 to move away from the rod body 7, so that the drive tube 12 moves out of the rod body 7.

[0036] In one embodiment of the present invention, as shown in FIG4, a limiting slide rail 16 is provided in the groove 10 structure, and the rod 7 structure is movably sleeved on the limiting slide rail 16.

[0037] It should be noted that the limiting slide rail 16 described in this embodiment limits the angle of the rod 7, ensuring that the hole on the rod 7 is aligned with the drive tube 12, and the drive tube 12 can be inserted into the hole to complete the fixing of the protective layer release rod 6.

[0038] In one embodiment of the present invention, as shown in FIG3, the fixing mechanism 5 includes a pressure roller 17 and an extrusion strip 18.

[0039] The extrusion strip 18 is located under the support plate 2, and the two ends of the pressure roller 17 are rotatably mounted on the inner side of the outer frame 4 and located below the extrusion strip 18.

[0040] It should be noted that the protective layer is held in place by the pressure roller 17 and the extrusion strip 18 to prevent the protective layer from moving around freely.

[0041] In one embodiment of the present invention, as shown in FIG3, the pressure roller 17 is provided with adjustment chambers 19 at both ends, and springs 20 are provided in the adjustment chambers 19. The top of the springs 20 is connected to the lower end of the pressure roller 17. A vertical rod 21 is provided in the adjustment chamber 19, and the vertical rod 21 passes through the spring 20. A movable collar 22 is movably sleeved on the vertical rod 21. A movable sleeve 26 is provided on the top of the spring 20 and connected to the pressure roller 17. A connecting block 23 is provided between the movable collar 22 and the pressure roller 17. The connecting block 23 is rotatably connected to the pressure roller 17. The connecting block 23 is movably inserted through the side wall of the adjustment chamber 19. An extension ring 24 is provided on the bottom surface of the movable collar 22, and the extension ring 24 is sleeved on the outside of the spring 20.

[0042] It should be noted that the pressure is provided by the spring 20, which controls the pressure roller 17 to press against the extrusion strip 18.

[0043] In one embodiment of the present invention, as shown in FIG5, the end of the extrusion strip 18 away from the notch structure is inclined downward and closely attached to the pressure roller 17.

[0044] It should be noted that the curved portion of the extrusion strip 18 increases the contact area between the extrusion strip 18 and the pressure roller 17 and the protective layer, thereby increasing the pressure exerted by the extrusion strip 18 and the pressure roller 17 on the protective layer.

[0045] In one embodiment of the present invention, as shown in FIG5, a spiral rod 25 is symmetrically provided under the support plate 2, a sleeve 26 is sleeved under the spiral rod 25, and a pad 27 is provided under the sleeve 26.

[0046] It should be noted that by rotating the sleeve 26, the staff adjusts the position of the sleeve 26 on the screw rod 25, and then the stretcher contacts the ground through the padding layer 1, which facilitates the placement of the stretcher.

[0047] In summary, the multi-functional rescue stretcher for fire rescue in this embodiment of the invention combines the use of a protective layer extending a pole and a fixing mechanism. The protective layer is laid on the padding layer to prevent injured personnel from coming into contact with the padding layer. At the same time, the protective layer can be replaced to prevent multiple injured personnel from using the same protective layer and reduce the risk of cross-infection.
