DETAILED DESCRIPTION

[0025] 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.

[0026] Example 1: Please refer to Figure 1-5 A portable folding stretcher with a placement structure in this embodiment includes a folding stretcher body 1, and a placement mechanism 2 is arranged below the folding stretcher body 1.

[0027] Two handles 3 are fixedly mounted on the left and right sides of the folding stretcher body 1 , and the folding stretcher body 1 can be lifted and moved by the four handles 3 .

[0028] Example 2: Please refer to Figure 1-3 On the basis of the first embodiment, the placement mechanism 2 includes a mounting plate 201 fixedly mounted on the bottom of the folding stretcher body 1, a fixed box 202 is fixedly mounted on the bottom of the mounting plate 201, vertical plates 203 are fixedly mounted on the front and back of the bottom of the mounting plate 201, a rotating rod 204 located inside the fixed box 202 is rotatably connected between opposite sides of the two vertical plates 203, a rotating shaft 205 having one end passing through and extending into the inside of the fixed box 202 is rotatably connected on the left side of the fixed box 202, an engaging assembly 206 for driving the rotating rod 204 to rotate is arranged on the outer side of the rotating shaft 205, two placement rods 207 are fixedly mounted on the outer side of the rotating rod 204, an adjusting assembly 208 is arranged at the bottom of the two placement rods 207, and a universal wheel 209 is arranged at the bottom of the two adjusting assemblies 208.

[0029] Among them, the right side of the rotating shaft 205 is rotatably connected to the right side wall of the inner cavity of the fixed box 202 to ensure the stability of the rotation of the rotating shaft 205. An adjusting handle is fixedly installed on the left side of the rotating shaft 205. When the adjusting handle is rotated, the adjusting handle will drive the rotating shaft 205 to rotate.

[0030] In addition, the meshing assembly 206 includes a worm 2061 fixedly mounted on the outside of the rotating shaft 205, and a worm wheel 2062 meshing with the worm 2061 is fixedly mounted on the outside of the rotating rod 204. When the rotating shaft 205 rotates, the rotating shaft 205 drives the worm 2061 to rotate, the worm 2061 drives the worm wheel 2062 meshing therewith to rotate, and the worm wheel 2062 drives the rotating rod 204 to rotate. The rotating shaft 205 can drive the rotating rod 204 to rotate through the worm 2061 and the worm wheel 2062.

[0031] It should be noted that the front and back sides of the fixed box 202 are provided with rotating holes that penetrate into the interior thereof, and the rotating rod 204 is rotatably connected to the inside of the two rotating holes. The rotating holes ensure the stability of the rotation of the rotating rod 204, and at the same time, ensure the stability of the rotation of the rotating rod 204 inside the fixed box 202. When the rotating rod 204 rotates, the rotating rod 204 will drive the two placement rods 207 to rotate, thereby adjusting the angle of the two placement rods 207.

[0032] Specifically, the two placement rods 207 are respectively located on the front and back of the fixed box 202. When the two placement rods 207 are rotated to the vertical direction, the folding stretcher body 1 can be placed and supported by the two placement rods 207 and the two universal wheels 209. When the two placement rods 207 are rotated to the horizontal direction, the folding stretcher body 1 can be folded and carried.

[0033] It should be noted that there are two groups of placement mechanisms 2, which are symmetrically distributed on the left and right sides of the bottom of the folding stretcher body 1. The two groups of placement mechanisms 2 can stably support the left and right sides of the folding stretcher body 1.

[0034] Example 3: Please refer to Figure 1 and Figure 4 On the basis of Embodiment 1 and Embodiment 2, the adjustment component 208 includes a threaded groove 2081 opened at the bottom of the two placement rods 207, the interiors of the two threaded grooves 2081 are threadedly connected with threaded rods 2082, the left sides of the two threaded rods 2082 are fixedly installed with rotating rods 2083, and the bottoms of the two threaded rods 2082 are respectively fixedly connected to the tops of the two universal wheels 209.

[0035] When the folding stretcher body 1 is placed and supported, the rotating rod 2083 is rotated, and the rotating rod 2083 drives the threaded rod 2082 to rotate. Under the action of the thread thrust of the thread groove 2081, the threaded rod 2082 moves upward or downward, and the threaded rod 2082 drives the universal wheel 209 to move upward or downward, thereby adjusting the distance between the universal wheel 209 and the bottom of the folding stretcher body 1, so that the folding stretcher body 1 can be placed more stably.

[0036] The working principle of the above embodiment is:

[0037] When the portable folding stretcher with a placement structure is in use, the adjustment handle is turned, and the adjustment handle drives the rotating shaft 205 to rotate, the rotating shaft 205 drives the worm 2061 to rotate, the worm 2061 drives the worm wheel 2062 engaged therewith to rotate, the worm wheel 2062 drives the rotating rod 204 to rotate, and the rotating rod 204 drives the two placement rods 207 to rotate, so as to adjust the angles of the two placement rods 207. When the two placement rods 207 are rotated to the vertical direction, the folding stretcher itself can be adjusted by the two placement rods 207 and the two universal wheels 209. The foldable stretcher body 1 is placed and supported. When the two placement rods 207 are rotated to the horizontal direction, the foldable stretcher body 1 can be folded and carried. When the foldable stretcher body 1 is placed and supported, the rotating rod 2083 is rotated, and the rotating rod 2083 drives the threaded rod 2082 to rotate. Under the thread thrust of the thread groove 2081, the threaded rod 2082 moves upward or downward, and the threaded rod 2082 drives the universal wheel 209 to move upward or downward, thereby adjusting the distance between the universal wheel 209 and the bottom of the foldable stretcher body 1, so that the foldable stretcher body 1 is placed more stably.
