The upper linear array has pin holes, and a frame is fixedly connected to the sleeve. A pin passes through the frame and enters the inside of the sleeve. An end plate is fixed to the upper end of the pin, and a spring is sleeved on the pin. One end of the spring is fixed to the frame, and the other end is fixed to the pin. Pulling the end plate can pull the pin out of the sleeve, allowing the telescopic rod to slide in the sleeve. By inserting the pin into the pin hole, the distance between the lifting rods can be adjusted, thus enabling stretcher lifting and emergency treatment for patients of different sizes, making it very convenient to use.

[0006] Furthermore, the sunshade assembly includes a support rod mounted on a fixed block. A sleeve is fixedly connected to the lower end face of the support rod, and a fastening bolt is threaded into the sleeve. A connecting rod is inserted into the sleeve, and the connecting rod has a threaded hole corresponding to the fastening bolt. A sunshade is provided at the lower end of the connecting rod. By inserting the connecting rod into the sleeve and tightening the fastening bolt, the sunshade can be disassembled and installed conveniently. The sunshade can provide rain and sun protection for patients on the canvas.

[0007] Preferably, the support rod has a rectangular cross-section and is inserted into the fixing block. The fixing block has multiple sets of fastening bolts threaded onto its side wall to facilitate disassembly of the support rod.

[0008] Preferably, the canvas is provided with a breathable mesh structure.

[0009] Preferably, the initial state of the spring is such that it can be inserted into the sleeve, and the pin hole on the telescopic rod and the pin are located on the same vertical plane.

[0010] Preferably, the sunshade is designed to be foldable.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model can flexibly adjust and lock the spacing of the stretcher lifting rods by setting a spacing adjustment device, which is suitable for patients of different sizes.

[0013] 2. This utility model enables the rapid assembly and splicing of sunshade umbrellas by setting sunshade components. On rainy days or in hot weather, it can protect patients from rain and sun, improving their comfort. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1-4 This utility model provides an easy-to-use emergency stretcher, including a lifting rod 1, a collar 2 sleeved on the lifting rod 1, a canvas 3 fixedly attached to the collar 2, the canvas 3 being arranged in a breathable mesh shape, a fixing block 4 fixedly attached to the outer wall of the lifting rod 1, a sunshade component 5 provided on the fixing block 4, and a spacing adjustment device 6 provided between the lifting rods 1.

[0022] like Figure 1 and 3 The spacing adjustment device 6 includes a sleeve 7, which is fixedly connected to one set of lifting rods 1. A telescopic rod 8 passes through the sleeve 7, and the end of the telescopic rod 8 is fixedly connected to another set of lifting rods 1. The telescopic rod 8 has pin holes 9 arranged in a straight line. A frame 10 is fixedly connected to the sleeve 7. A pin 11 passes through the frame 10 and is inserted into the sleeve 7. An end plate 12 is fixedly connected to the upper end of the pin 11. A spring 13 is sleeved on the pin 11, and one end of the spring 13 is fixedly connected to the frame 10. The other end is fixed to the pin 11. The initial state of the spring 13 is such that it can be inserted into the sleeve 7. The pin hole 9 on the telescopic rod 8 and the pin 11 are located on the same vertical plane. Pulling the end plate 12 can pull the pin 11 out of the sleeve 7, so that the telescopic rod 8 can slide in the sleeve 7. By inserting the pin 11 into the pin hole 9, the distance between the lifting rods 1 can be adjusted, so that patients of different sizes can be lifted on a stretcher for emergency treatment. It is very convenient to use.

[0023] like Figure 1-2The sunshade assembly 5 includes a support rod 14, which is mounted on a fixing block 4. The support rod 14 has a rectangular cross-section and is inserted into the fixing block 4. Multiple sets of fastening bolts 20 are threaded onto the side wall of the fixing block 4 to facilitate the disassembly of the support rod 14. A sleeve 15 is fixed to the lower end face of the support rod 14. A fastening bolt 16 is threaded into the sleeve 15, and a connecting rod 17 is inserted into the sleeve 15. The connecting rod 17 has a threaded hole 18 that corresponds to the fastening bolt 16. A sunshade umbrella 19 is provided at the lower end of the connecting rod 17. The sunshade umbrella 19 is foldable. By inserting the connecting rod 17 into the sleeve 15 and tightening the connecting rod 17 with the fastening bolt 16, the sunshade umbrella 19 can be disassembled and installed, which is very convenient. The sunshade umbrella 19 can provide rain and sun protection for patients on the canvas 3.

[0024] In practical use, when it is necessary to adjust the spacing between the lifting rods 1 of the stretcher, by pulling the end plate 12, the pin 11 slides in the frame 10 until it disengages from the sleeve 7. Then, by pushing the lifting rods 1 on both sides, the telescopic rod 8 will slide in the sleeve 7 until the spacing is appropriate. After releasing the end plate 12, the pin 11 will be inserted back into the pin hole 9 in the telescopic rod 8 under the action of the spring 13, thus completing the locking. In this way, the spacing between the lifting rods 1 can be flexibly adjusted.

[0025] When treating the wounded on a rainy day, the support rod 14 is inserted into the fixing block 4 and fastened with the second fastening bolt 20. The connecting rod 17 is inserted into the sleeve 15 and fastened with the first fastening bolt 16. This completes the quick installation and connection of the sunshade 19. The sunshade 19 can be folded and opened to protect the wounded from rain and also provide shade.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
