The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0019] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a foldable emergency stretcher, including a support cloth 2 and multiple support rods 1. The support cloth 2 is installed between the multiple support rods 1. Each support rod 1 has a mounting groove 8 on its opposite surface. Each mounting groove 8 has a rack 13. Each side of the rack 13 has multiple gears 9 that mesh with it. Each gear 9 has a support plate 5 installed on its side away from the support cloth 2. The other end of each support plate 5 extends to the outside and is in contact with each other. The back of the support cloth 2 is placed on the multiple support plates 5. One end of the rack 13 is equipped with an adjustment mechanism that drives the support plates 5 to fold and enter the mounting groove 8.

[0021] In this embodiment, the trays 5 are arranged in pairs facing each other. Studs 6 are installed on the opposite surfaces of the outer trays 5. Connecting sleeves 7 are sleeved between the studs 6. The connecting sleeves 7 are threadedly connected to the studs 6. The connecting sleeves can be used to position the trays laterally, thus preventing the trays from rotating again.

[0022] In this embodiment, the adjustment mechanism includes a lead screw 12, a sealed bearing, and a gripping rod 4. One end of the rack 13 is provided with a lead screw hole, and one end of the bearing rod 1 is provided with a mounting hole opposite to the lead screw hole. The sealed bearings are all installed in the mounting holes, and the lead screw 12 is all installed in the inner ring of the sealed bearing. One end of the lead screw 12 is threaded into the lead screw hole, and the other end is set to the outside and is fixedly connected to the gripping rod 4.

[0023] In this embodiment, the inner wall surface of the mounting groove 8 is provided with positioning grooves opposite to the rack 13, and positioning strips 11 are installed on the opposite surface of the rack 13. The positioning strips 11 are slidably disposed in the positioning grooves, and the cross sections of the positioning strips 11 and the positioning grooves are both trapezoidal.

[0024] In this embodiment, a shaft 10 connected to the support plate 5 is installed at the center of each gear 9. The top and bottom surfaces of the mounting groove 8 are provided with shaft holes opposite to the shaft 10. Both ends of the shaft 10 are inserted into the shaft holes, so that the gear and the support plate can only rotate around the shaft.

[0025] In this embodiment, the side of the support plate 5 away from the support cloth 2 is in contact with the inner wall of the mounting groove 8. The weight on the support cloth can act on the support plate, and the weight on the support plate can act on the bearing rod.

[0026] In this embodiment, hand-held levers 3 are installed at both ends of the support rod 1, allowing the operator to hold the hand-held levers and lift the device upwards.

[0027] When in use, the screw can be rotated by holding the lever. The rotation of the screw drives the rack, which moves along the positioning groove. The movement of the rack drives the gear, which in turn drives the support plate, causing the support plate to rotate to the outside and be placed on the bottom surface of the support cloth. This provides support for the bottom surface of the support cloth and prevents the load-bearing rod from moving inward.

[0028] To increase the stability of the pallet, a rotatable connecting sleeve is used, which is threaded onto the studs. The connecting sleeve can position the entire pallet, preventing it from rotating on its own. While providing support for the support cloth, the pallet can also restrict the load-bearing rods, preventing them from pulling inward and causing discomfort during use.

[0029] When not in use, rotate the connecting sleeve to disengage it from the studs, then rotate the screw in the opposite direction to move the rack in the opposite direction, which in turn drives the gear and the tray to rotate in the opposite direction. This causes the tray to fold into the mounting slot around the shaft, allowing it to be hidden inside the mounting slot and avoiding exposure. This reduces the size and makes it easier to store and carry.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
