The support beam 3 is located between the two vertical rods 22, and both ends thereof are fixedly connected to the vertical rods 22; the legs 4 include a bottom support rod 41 and an inclined support rod 42, both the bottom support rod 41 and the inclined support rod 42 are telescopic rods that can be telescoped along their own axial directions. One end of the bottom support rod 41 is hinged to the middle of the bottom beam 21, and the other end is hinged to the inclined support rod 42. The end of the inclined support rod 42 away from the bottom support rod 41 is hinged to the middle of the support beam 3. The connecting folding rod 5 includes a first folding rod 51 and a second folding rod 52. One end of the first folding rod 51 is hinged to the bottom beam 21 of one of the support assemblies 1, and the other end is hinged to the second folding rod 52. The end of the second folding rod 52 away from the first folding rod 51 is hinged to the bottom beam 21 of the other support assembly 1.

[0029] Referring to Figure 4 , when the temporary support device for the medical stretcher is in use, the two support assemblies 1 are moved apart so that the connecting folding rod 5 is unfolded into a straight line. Subsequently, the legs 4 on the U-shaped frame 2 are unfolded so that the support assembly 1 forms a stable triangular structure. Subsequently, the stretcher can be placed on the support beam 3 of the support assembly 1 and supported; when not in use, the legs 4 can be retracted, and then the two support assemblies 1 are moved together so that the connecting folding rod 5 is folded between the two support assemblies 1 to complete the folding of the support device. The use operation is convenient, and it occupies a small space when not in use, which is convenient for storage and transportation; the setting of the connecting folding rod 5 can limit the distance between the two support assemblies 1, realizing the rapid positioning of the two support assemblies 1 during use, and there is no need for manual adjustment every time it is used, making the use process more convenient.

[0030] In this embodiment, the angle between the plane where the U-shaped frame 2 is located and the axis of the bottom support rod 41 is an acute angle. Preferably, the angle between the two is between 80° and 60° to improve the bearing capacity and stability of the support assembly 1 and prevent it from collapsing or tipping over easily.

[0031] Referring to Figure 3, the bottom support rod 41 includes a bottom support sleeve 411, a bottom support movable rod 412 and a first locking bolt 413; the bottom support movable rod 412 is movably inserted through one end of the bottom support sleeve 411, and one end of the bottom support sleeve 411 away from the bottom support movable rod 412 is hinged to the middle of the corresponding bottom beam 21, and one end of the bottom support movable rod 412 away from the bottom support sleeve 411 is hinged to the corresponding diagonal support rod 42. The first locking bolt 413 is inserted through the outer peripheral surface of one end of the bottom support sleeve 411 away from the bottom beam 21 and is threadedly connected to the bottom support sleeve 411. One end of the first locking bolt 413 inserted into the bottom support sleeve 411 abuts against the bottom support movable rod 412, thereby realizing the relative fixation between the bottom support sleeve 411 and the bottom support movable rod 412. A first sleeve 414 is fixed to one end of the bottom support sleeve 411 away from the bottom support movable rod 412. The first sleeve 414 is coaxially sleeved on the bottom beam 21, and the outer diameter of the first sleeve 414 is the same as the outer diameter of the bottom beam 21.

[0032] By sliding and adjusting the position of the bottom support movable rod 412, and then tightening the first locking bolt 413 to fix the bottom support movable rod 412 and the bottom support sleeve 411, the function of the bottom support rod 41 to expand and contract along its own axis can be realized, which is convenient for the telescopic folding of the bottom support rod 41. The end of the bottom support rod 41 is hinged to the bottom beam 21 through the first sleeve 414. The outer diameter of the first sleeve 414 is the same as the outer diameter of the bottom beam 21, so as to ensure the flatness of the bottom of the support assembly 1, and then ensure the support stability and firmness of the support assembly 1.

[0033] Refer to Figure 3 , the diagonal support rod 42 includes a diagonal support sleeve 421, a diagonal support movable rod 422 and a second locking bolt 423; the diagonal support movable rod 422 is movably inserted through one end of the diagonal support sleeve 421, and one end of the diagonal support sleeve 421 away from the diagonal support movable rod 422 is hinged to the middle of the corresponding support beam 3, and one end of the diagonal support movable rod 422 away from the diagonal support sleeve 421 is hinged to the corresponding bottom support rod 41. The second locking bolt 423 is inserted through the outer peripheral surface of one end of the diagonal support sleeve 421 away from the support beam 3 and is threadedly connected to the diagonal support sleeve 421. One end of the second locking bolt 423 inserted into the diagonal support sleeve 421 abuts against the diagonal support movable rod 422, thereby realizing the relative fixation between the diagonal support sleeve 421 and the diagonal support movable rod 422. A second sleeve 424 is fixed to one end of the diagonal support sleeve 421 away from the diagonal support movable rod 422. The first sleeve 414 is coaxially sleeved on the support beam 3, and the outer diameter of the second sleeve 424 is the same as the outer diameter of the support beam 3.

[0034] By sliding to adjust the position of the diagonal brace movable rod 422, and then tightening the second locking bolt 423 to fix the diagonal brace movable rod 422 to the diagonal brace sleeve 421, the function of the diagonal brace rod 42 to expand and contract along its own axis can be realized, which is convenient for the telescopic folding of the diagonal brace rod 42. Cooperating with the bottom brace rod 41 can also realize the adjustment of the inclination angle of the U-shaped frame 2, indirectly changing the support height, and having better versatility. The end of the diagonal brace rod 42 is hinged to the bottom beam 21 through the second sleeve 424. The outer diameter of the second sleeve 424 is the same as the outer diameter of the support beam 3, so as to ensure the flatness of the surface of the support beam 3, and then ensure the support effect on the stretcher.

[0035] Referring to Figure 2 and Figure 4 , in this embodiment, there are two connecting folding rods 5, and the two connecting folding rods 5 are connected to both ends of the bottom beam 21 of the support assembly 1. A groove 511 for accommodating the second folding rod 52 is formed on the bottom surface of the first folding rod 51, so that the cross-sectional shape of the first folding rod 51 is inverted U-shaped. One end of the second folding rod 52 far from the support assembly 1 is located in the groove 511 of the second folding rod 52 and is hinged to the first folding rod 51. Sleeves are fixed to the mutually remote ends of the first folding rod 51 and the second folding rod 52, and are hinged to the corresponding bottom beam 21 through the sleeves. The design of the connecting folding rod 5 can limit the distance between the two support assemblies 1, realize the rapid positioning of the two support assemblies 1 during use, realize the rapid matching with the stretcher, and there is no need for manual adjustment during each use, making the use process more convenient.

[0036] Referring to Figure 2 , in order to prevent the connecting folding rod 5 from not being able to be smoothly unfolded into a straight line due to the uneven bottom surface during use, two buffer spacers 211 made of rubber are sleeved and adhesively fixed on the bottom beam 21. The support assembly 1 contacts the ground through the buffer spacers 211. On the one hand, it plays a certain protective role for the support device. On the other hand, it can lift the connecting folding rod 5, reduce the influence of the ground flatness on the connecting folding rod 5, and enable the connecting folding rod 5 to be smoothly unfolded.

[0037] Referring to Figure 5 and Figure 6 , in some embodiments, the first folding rod 51 and the second folding rod 52 also both adopt telescopic rods that can expand and contract along their own lengths, and then the fixed distance between the two support assemblies 1 can be adjusted, so that the support device can better adapt to stretchers of different length models, and has a wider applicability.

[0038] Specifically, both the first folding rod 51 and the second folding rod 52 include a fixed rod section 53 and a sliding rod section 54. The sliding rod section 54 slidably penetrates through the fixed rod section 53. One end of the fixed rod section 53 away from the sliding rod section 54 is hinged to the corresponding bottom beam 21. The sliding rod sections 54 of the first folding rod 51 and the second folding rod 52 are hinged to each other. A jack 531 is formed in the top wall of the end of the fixed rod section 53 away from the bottom beam 21. A locking pin 55 penetrates through the jack 531. A plurality of adjustment holes 541 are formed in the top wall of the sliding rod section 54. One end of the locking pin 55 inserted into the jack 531 is inserted into the adjustment hole 541, thereby realizing the relative fixation of the fixed rod section 53 and the sliding rod section 54. By sliding and adjusting the position of the sliding rod section 54 and changing the hole position of the adjustment hole 541 into which the locking pin 55 is inserted, the lengths of the first folding rod 51 and the second folding rod 52 are changed, thereby improving the applicability of the support device.
