DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example 1: Refer to the attached specification Figure 1-4 The utility model is a transport vehicle for emergency patients, comprising a transfer vehicle 1, see Figure 3 A support 2 is fixedly installed on the top of the transfer vehicle 1. A knob 3 is rotatably connected to the top of the support 2. A gear 4 is fixedly connected to the bottom of the knob 3. The gear 4 is rotatably connected to the inside of the support 2. Two racks 5 are meshed on the outer wall of the gear 4. The two racks 5 are slidably connected to the inside of the support 2. The outer walls of the two racks 5 are fixedly connected to fixed plates 6. The fixed plates 6 are slidably connected to the inside of the support 2. For details, see Figure 4A card slot 7 is provided inside the support member 2, a card slot 7 is inserted with a card ring 8, a stretcher pole 9 is fixedly installed inside the card ring 8, handles 10 are fixedly connected to both ends of the stretcher pole 9, and a ring 11 is sleeved on the outer wall of the stretcher pole 9.
[0023] It should be noted that, when the medical staff encounters some places that are inconvenient for the transfer vehicle 1, the medical staff can turn the knob 3 to make the knob 3 drive the gear 4 to rotate, and then the gear 4 drives the rack 5 to slide along the inside of the support 2, so that the rack 5 pulls the fixing plate 6 to disengage from the top of the clamping ring 8. At this time, the medical staff can use the handle 10 to remove the long stretcher rod 9, the short stretcher rod 12, and the stretcher cloth 13 to form a stretcher structure. Then the medical staff can use the stretcher structure to enter some places that are inconvenient for the transfer vehicle 1 to enter, transport the patient out, and then Then, the medical staff can place the stretcher structure together with the patient on the top of the transfer vehicle 1, and make the clamping ring 8 fit into the inside of the clamping groove 7. Finally, the medical staff can reversely rotate the knob 3 to finally make the fixing plate 6 fit on the top of the clamping ring 8, and limit the clamping ring 8 so that the stretcher structure can be fixed on the transfer vehicle 1 without shaking, so as to achieve the effect of separating the transfer vehicle 1 from the stretcher structure and entering a place where it is inconvenient for the transfer vehicle 1 to transport the patient out, and the stretcher structure can be quickly reinstalled on the transfer vehicle 1, so that the medical staff can quickly transport the patient.
[0024] Embodiment 2: The outer wall of the collar 11 is fixedly connected to a stretcher short bar 12, the outer wall of the stretcher short bar 12 is sleeved with a stretcher cloth 13, and the stretcher cloth 13 is sleeved on the outer wall of the stretcher long bar 9, see Figure 1 The outer wall of the stretcher cloth 13 is fixedly connected with a fixing belt 14, see Figure 4 One end of the handle 10 is rotatably connected to a rotating member 15, one side of the rotating member 15 is fixedly connected to a threaded rod 16, the threaded rod 16 is rotatably connected to the inside of the handle 10, the outer wall of the threaded rod 16 is threadedly connected to a threaded sleeve 17, the threaded sleeve 17 is slidably connected to the inside of the stretcher long rod 9, one end of the threaded sleeve 17 is fixedly connected to an airbag 18, one side of the airbag 18 is fixedly installed inside the stretcher long rod 9, the outer wall of the airbag 18 is fixedly installed with a clamping block 19, and the clamping block 19 is slidably connected to the inside of the stretcher long rod 9.
[0025] It should be noted that when the medical staff needs to transfer the patient from the transfer vehicle 1 to the operating table, the medical staff can remove the stretcher structure and place the stretcher structure and the patient on the operating table. Then the medical staff can rotate the rotating member 15 so that the rotating member 15 drives the threaded sleeve 17 to stop squeezing the airbag 18 through the threaded rod 16, and the airbag 18 loses the pressure to push the block 19, so that the airbag 18 begins to shrink and pulls the block 19 out of the inside of the ring 11, so that the block 19 stops limiting the position between the ring 11 and the stretcher rod 9, and then the medical staff can use the handle 10 to pull the stretcher rod 9 out of the ring 11 and the stretcher cloth 13. After the long stretcher pole 9 is pulled out, the inside of the ring 11 loses the long stretcher pole 9, so that the medical staff can pull out the short stretcher pole 12 from the inside of the stretcher cloth 13 through the ring 11, so that the stretcher cloth 13 loses the supporting long stretcher pole 9 and the short stretcher pole 12, so as to achieve the effect of directly transferring the patient to the operating table, without the medical staff manually transferring the patient to the operating table, resulting in secondary injury to the patient, and by pulling out the long stretcher pole 9 and the short stretcher pole 12, it can be prevented that the medical staff controls the operating table to adjust the body position according to the needs of the surgical operation, and a convenient operating environment is provided for the doctor, while the long stretcher pole 9 and the short stretcher pole 12 block the deformation of the operating table and affect the operation on the patient.
