[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0036] As Figure 1 shown, the embodiment of the utility model provides an improved roll type stretcher, including stretcher body 1, reinforcing plate 3, support assembly 2, reinforcing plate 3 is fixed in the side edge and / or end edge of stretcher body 1, as Figure 4 shown, the design of this reinforcing plate 3, according to the need reinforcing plate 3 is provided with two groups and is arranged on the left and right side surfaces and foot of stretcher body 1 respectively, the triangle of reinforcing plate 3 is with relatively stable structure (equilateral triangle is adopted in the application). When being subjected to tension, the stress is relatively uniform, and it is not easy to be damaged, and the through hole 301 (the through hole 301 is arranged in three angle positions equally divided along reinforcing plate 3 at this time, and stress balance can be realized) is formed in reinforcing plate 3, and the through hole 301 is connected with the external rope, that is, the fixation of the whole stretcher body 1 is formed.

[0037] The structure of reinforcing plate 3 can also be designed into, for example, a circular shape or a rectangular shape, and the relative position of the through hole 301 in reinforcing plate 3 can be adjusted according to the need.

[0038] As Figure 7 shown, the embodiment of the utility model provides an improved roll type stretcher, including stretcher body 1, support assembly 2, and without the design of reinforcing plate 3, which does not affect the function of the whole structure, and is also within the protection scope of the application.

[0039] A plurality of mounting holes 101 are further arranged on the stretcher body 1 for mounting floating rods and the like, so that the stretcher can float on the water surface during offshore rescue, and the wounded person is conveniently transported. In addition, the mounting hole 101 design of the more sites is further provided with a rope through fixation for the local position of the lifted and transported wounded patient. In order to reduce the scratch of the rope during fixation, the edge position of the through hole 301 for the rope through and the mounting hole 101 is provided with a metal ring in the time use link.

[0040] The support assembly 2 is located in the middle of the stretcher body 1 and is provided with multiple groups; the support assembly 2 comprises a support strip 21 and a positioning assembly 23 and a fixing assembly 22 arranged at the end, the support strip 21 is in a long strip structure as a whole and can be detachably connected.

[0041] As shown in Figure 2 , Figure 3 , the positioning assembly 23 and the fixing assembly 22 are fixed on the upper surface of the stretcher body 1, and in order to reduce scratching, they can be arranged on the surface of the stretcher body 1 by a rivet fixing mode, which is simple and firm to fix and ensures the smoothness of the upper surface. The positioning assembly 23 is provided with a blind hole 231, which forms a blocking and fixing of one end of the support strip 21 (that is, when one end of the support strip 21 is inserted into one end of the blind hole 231, it cannot be pulled out from the other end), which effectively fixes and supports one end of the support strip 21. The fixing assembly 22 is provided with a through hole 221 with two ends communicating, which can realize the front and rear penetration of the support strip 21, and is provided with a locking block 222 perpendicular to the length direction of the support strip 21 in the through hole 221, which forms a blocking and fixing of the other end of the support strip 21 through the locking block 222.

[0042] As shown in Figure 5 , Figure 6 , that is, when the support strip 21 is installed, it directly penetrates the through hole 221 of the fixing assembly 22 (at this time, the through hole 221 is not blocked by the locking block 222, so it is a structure that penetrates front and back, which can realize the penetration of the support strip 21 in the length direction), until one end of it is fixed against the end of the blind hole 231 of the positioning assembly 23, then it is fixed in the fixing assembly 22 through the locking block 222, which forms a synchronous blocking and fixing of the other end of the support strip 21. In order to ensure that the support strip 21 is not easy to penetrate when blocking, the locking block 222 is transversely arranged in the through hole 221, and its thickness is slightly smaller than the inner wall size of the through hole 221, so it will not cause the support strip 21 to slip from the gap between the through hole 221 and the locking block 222.

[0043] According to the needs, the positioning assembly 23 and the fixing assembly 22 used for limiting and fixing the two ends of the support strip 21 can also be directly fixed by the fixing assembly 22, which is within the protection scope of the present application (not shown in the figure).

[0044] The locking block 222 can be inserted or pulled out as needed, that is, the upper surface where the fixing assembly 22 is located is provided with a connecting hole 223 for inserting the locking block 222 (the connecting hole 223 is upward, facilitating the insertion of the locking block 222, and at this time the locking block 222 is made of wear-resistant soft material and can be bent and deformed to a certain extent), and when the locking block 222 is inserted into the through hole 221 through the connecting hole 223, the other end of the supporting strip 21 is blocked and fixed; when the locking block 222 is disconnected from the through hole 221 through the connecting hole 223, the supporting strip 21 is moved out of the other end of the connecting hole 223 of the fixing assembly 22, and the through hole 221 after moving out is a front and rear through structure, which can form a through hole (that is, the supporting strip 21 is completely separated from the stretcher body 1).

[0045] Because the length of the supporting strip 21 in the length direction is relatively long, direct fixation at both ends is also prone to slipping, so when the positioning assembly 23 and the fixing assembly 22 form a fixed supporting strip 21, the middle part of the supporting strip 21 is penetrated by the limiting assembly 24, the supporting strip 21 is penetrated into the hole in the middle part of the limiting assembly 24, and the front and rear end faces and the width direction are fixed (the length direction still allows the supporting strip 21 to move), and at this time the limiting assembly 24 is fixed on the stretcher body 1 (and the through holes for the supporting strip 21 to penetrate / connect in the middle part of the positioning assembly 23, the fixing assembly 22 and the limiting assembly 24 are on a straight line), so the supporting strip 21 can be fixed.

[0046] Because the supporting strip 21 is arranged only in the length direction, it is easy to cause instability in the width direction (that is, the supporting strip 21 exposed between the positioning assembly 23, the fixing assembly 22 and the limiting assembly 24 is prone to deformation in the width direction), so in the width direction, the positioning assembly 23 for fixing the supporting strip 21 and both ends is arranged, so that the supporting strip 21 distributed in the width direction is pressed and fixed to the supporting strip 21 distributed in the length direction. The supporting strip 21 is distributed in multiple groups and staggered, and multiple groups of supporting strips 21 form a supporting surface on the stretcher body 1. During the entire installation process, the supporting strip 21 in the length direction is installed first, and then the supporting strip 21 in the width direction is installed (because the width direction is shorter, the deformation amount is smaller, and the supporting strip 21 in the width direction can lock the supporting strip 21 in the length direction), which ensures the cross support of the length direction and the width direction, forms a whole supporting surface, and makes the supporting surface more stable.

[0047] The positioning assembly 23, the fixing assembly 22 and the limiting assembly 24 each comprise a base 201 at the bottom and a panel 202 at the upper portion, and a through slot (which can be a blind slot or a through slot according to the actual use of the positioning assembly 23, the fixing assembly 22 and the limiting assembly 24) is formed on the upper surface of the base 201, so that the panel 202 covers the fixing on the base 201 (that is, the upper surface of the through slot is covered to form a through hole / blind hole structure).

[0048] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
