DETAILED DESCRIPTION

[0037] The technical solutions of the utility model will be described clearly and completely in combination with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0038] The utility model embodiment specifically provides a foldable stretcher, please refer to Figure 1 , including main skeleton 1, auxiliary skeleton 2, stretcher surface 3 and caster 4.

[0039] Among them, auxiliary skeleton 2 is rotatably installed on main skeleton 1, and the left and right sides of stretcher surface 3 are fixed with auxiliary skeleton 2, and caster 4 is fixedly installed at the bottom end of main skeleton 1 and auxiliary skeleton 2, the material of stretcher surface 3 is canvas, the compressive strength is strong, and stretcher surface 3 can be folded, and the surface of stretcher surface 3 is sewn with a bag 31, which can be used to place AED and some first-aid supplies.

[0040] Specifically, main skeleton 1 includes locking piece 11 and supporting piece 12, locking piece 11 is fixedly installed on the surface of supporting piece 12, and auxiliary skeleton 2 is installed on locking piece 11 to provide the installation support of unfolding fixation and folding for auxiliary skeleton 2 through locking piece 11.

[0041] Further, please refer to Figure 2 Auxiliary skeleton 2 includes first supporting rod 21 and second supporting rod 22 rotatably installed on locking piece 11, so that the two supporting rods can rotate close to each other or away from each other, so as to be folded when not needed, and quickly unfolded when used, and provide support.

[0042] Among them, please refer to Figure 3The locking member 11 comprises a side plate 111, a sliding frame 112, a pressing frame 113 and a spring 114. The bottom end of the side plate 111 is fixedly connected with the supporting member 12. The sliding frame 112 is slidingly installed on the side plate 111. The pressing frame 113 is fixedly connected with the sliding frame 112 at the outer side. The bottom surface of the pressing frame 113 is in abutting contact with the first supporting rod 21 and the second supporting rod 22. The two ends of the spring 114 are fixedly connected with the side plate 111 and the pressing frame 113 respectively. The sliding frame 112 is in the shape of a cuboid, so that the sliding frame 112 can only move linearly left and right.

[0043] When it is needed to fold and rotate the first supporting rod 21 and the second supporting rod 22, the sliding frame 112 can be pushed by the foot, so that the pressing frame 113 moves inward and separates from the first supporting rod 21 and the second supporting rod 22, so that the first supporting rod 21 and the second supporting rod 22 can rotate close to each other. Then, when it is needed to unfold, the pressing frame 113 is reset by the spring 114 to fix the upper surfaces of the first supporting rod 21 and the second supporting rod 22.

[0044] Further, please refer to Figure 4 The supporting member 12 comprises a first supporting frame 121 and a second supporting frame 122. The upper surfaces of the first supporting frame 121 and the second supporting frame 122 are fixedly connected with the side plate 111. The first supporting frame 121 and the second supporting frame 122 are fixedly and rotatably connected by a fixing member 123 and a rotating member 124 respectively, so that the first supporting frame 121 and the second supporting frame 122 can rotate. When the first supporting rod 21 and the second supporting rod 22 are folded and rotated, the two supporting frames are further folded and stored, so that the four sides are folded, the area of placement is reduced, and the stretcher is convenient to carry.

[0045] The top end of the caster 4 is fixedly connected with the first supporting rod 21, the second supporting rod 22, the first supporting frame 121 and the second supporting frame 122. After being folded, the caster 4 at the bottom end of the first supporting frame 121 and the second supporting frame 122 contacts the ground to support the folded stretcher.

[0046] Specifically, please refer to Figure 5The fixing component 123 includes a positioning frame 125, a sliding plate 126, and a first magnetic plate 127. The positioning frame 125 is fixedly installed on the outside of the first support 121 and the second support 122. The sliding plate 126 is inserted into the inner wall of the positioning frame 125. The first magnetic plate 127 is fixedly installed on the outside of the first support 121 or the second support 122. One end of the sliding plate 126 is magnetically connected to the first magnetic plate 127. The sliding plate 126 is made of magnetic metal material. When the first support 121 and the second support 122 need to be folded, the sliding plate 126 only needs to be moved close to the first magnetic plate 127 to separate it from the positioning frame 125 on one of the supports, so that the sliding plate 126 and the first magnetic plate 127 are magnetically attracted, and then the first support 121 and the second support 122 can be rotated. In daily use, the two supports can also improve the stability of the supports by inserting the sliding plate 126 into the two positioning frames 125.

[0047] The rotating component 124 includes a receiving plate 128 and a support cylinder 129. One end of the receiving plate 128 is fixedly connected to the first support frame 121, and the other end is rotatably mounted on the support cylinder 129. The outer side of the support cylinder 129 is fixed to the second support frame 122, so that the first support frame 121 and the second support frame 122 can rotate and fold relative to each other, improving storage convenience.

[0048] Further, please refer to Figure 2 The first support rod 21 has a towing component 23 on its upper surface, and the second support rod 22 has a placement groove 24 on its upper surface. The horizontal area of ​​the placement groove 24 is greater than the horizontal area of ​​the towing component 23, and the depth of the placement groove 24 is greater than the height of the towing component 23. Thus, when the first support rod 21 and the second support rod 22 are compressed and folded, the towing component 23 can be placed into the placement groove 24 to improve the folding convenience.

[0049] Specifically, a second magnetic plate 25 is fixedly installed on the upper surface of the first support rod 21, and the second support rod 22 is made of magnetic metal material. When the first support rod 21 is folded, it can be magnetically attracted and stored by the second magnetic plate 25 and the second support rod 22.

[0050] The towing assembly 23 includes a rotating frame 231, a support 232, and a third magnetic plate 233. The bottom end of the rotating frame 231 is rotatably connected to the support 232. The support 232 is fixedly installed on the upper surface of the first support rod 21. The bottom end of the third magnetic plate 233 is fixed to the first support rod 21. The bottom surface of the rotating frame 231 is magnetically connected to the third magnetic plate 233. The rotating frame 231 is made of magnetic metal material. When the patient lies on the stretcher and needs to move the casters 4, it is only necessary to lift the rotating frame 231 and pull the rotating frame 231 to move the entire stretcher.

[0051] During implementation, the end of the rotating frame 231 away from the support 232 is provided with anti-slip texture 234 to improve the force application effect of pulling the rotating frame 231 by hand.

[0052] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
