[0023] The specific implementation method of this embodiment is: first, through the two groups of first diagonal support frames 2105 and second diagonal support frames 2106, respectively, they are connected in a cross-rotating manner, and then two groups of spring buffer components are used to perform shock absorption and buffering on the cross-type frame. Specifically, when the transfer device is walking normally, the buffer unit 21 may have a slight buffering effect. If it enters a bumpy road at this time, the feedback from the uneven road surface will be transmitted from the universal wheel 12 to the top of the bottom frame 2102. Since there is a patient lying on the bed board 11, it is pressed down by the weight. At this time, the top frame 2101 will have a downward pressure force. At this time, the two ends of the two first diagonal support frames 2105 are respectively rotatably connected to the two rotating seats 2111 and the two hinged seats 2104, and the two ends of the two second diagonal support frames 2106 are respectively connected to the other two rotating seats 2111 and the hinged seats 21 04 rotating connection, and utilizing the relationship between two of the rotating seats 2111 sliding on the inner wall of the top frame 2101 and two of the hinged seats 2104 sliding on the inner wall of the bottom frame 2102, so as to achieve the effect that the support structure has up and down ups and downs bumping, at this time, the two sets of spring buffer components are used to buffer the bumps, firstly, the buffer rod 2109 is located inside the buffer sleeve 2108 and slides, so that the buffer sleeve 2108 can limit the buffer rod 2109, and a first spring 2110 is installed between the buffer rod 2109 and the buffer sleeve 2108, and then when the support frame body bumps up and down, the first spring 2110 will be squeezed or stretched, and at this time, the characteristics of the first spring 2110 can be used to effectively alleviate the bumps, and the buffering effect is made more obvious by providing two sets of such buffer components.

[0024] Example 2: Please refer to Figure 1-Figure 13 The present invention provides a technical solution: a safe transfer device for critically ill patients. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The shock absorbing mechanism 2 also includes a tightening unit 22, which is fixed to the inner wall of the bed board 11. The tightening unit 22 can tighten the patient's body according to the size of the bumps in real time according to the road condition feedback. It has a better effect of protecting the patient under bumpy road conditions and preventing secondary injuries to the patient. A protective mechanism 3 is arranged on the outside of the bed board 11.

[0025] As a further limitation of the shock absorbing mechanism 2 of the present invention, the tightening unit 22 includes two rotating shafts 2201, the outer surface of each rotating shaft 2201 is rotatably connected to the inner wall of the bed board 11, the outer surface of each rotating shaft 2201 is rotatably connected to a winding box 2202, the front of each winding box 2202 is fixedly connected to a force storage box 2203, the inner wall of each force storage box 2203 is fixedly connected to a torsion spring 2204, the end of each torsion spring 2204 away from the force storage box 2203 is fixedly connected to the inner wall of the rotating shaft 2201, the inner wall of each rotating shaft 2201 is fixedly connected to a tightening belt 2205, and the end of each tightening belt 2205 away from the rotating shaft 2201 passes through the winding box 2202 and is fixedly connected There is a buckle 2210, and the outer surface of each rotating shaft 2201 is fixedly connected to two baffles 2206, and the inner wall of each rotating shaft 2201 is fixedly connected to a tension rope 2207, and the end of each tension rope 2207 away from the rotating shaft 2201 is fixedly connected to an anti-detachment hook 2209, and the anti-detachment hook 2209 is used in conjunction with a fixing ring 2112, and the outer surface of each tension rope 2207 is fixedly connected to a counterweight block 2208. By setting a tightening unit 22, the patient's body can be tightened in real time according to the bumpiness of the road feedback, which has a better effect of protecting the patient under bumpy road conditions and preventing secondary injuries to the patient. When the road surface is restored to be flat, it will automatically adjust to a comfortable tightness to improve the comfort of the patient; Two adjustment seats 2211 are fixedly connected to the inner wall of the bed board 11. A lock buckle 2212 is rotatably connected to the inner wall of each adjustment seat 2211. The adjustment seat 2211 is used to connect the lock buckle 2212 and the bed board 11. The adjustment seat 2211 is softly connected to the lock buckle 2212 by a strap, so that the lock buckle 2212 has more room for movement. The front of each energy storage box 2203 is fixedly connected to two limiting bars 2213, and the outer surface of each limiting bar 2213 is slidably connected to the inner wall of the bed board 11. The two limiting bars 2213 fixedly connected to the energy storage box 2203 can limit the energy storage box 2203, so that the energy storage box 2203 can be stuck inside the bed board 11; The inner wall of the bed board 11 is slidably connected with four limit rods 2214, and the upper surface of each limit rod 2214 is fixedly connected to a limit block 2215, and the outer surface of each limit block 2215 is in contact with the outer surface of the rotating shaft 2201. By utilizing the fixed connection between the limit rod 2214 and the limit block 2215, the limit block 2215 will move with the limit rod 2214 when being pulled down or moved up; The outer surface of each limit rod 2214 is fixedly connected to a limit plate 2216, the upper surface of each limit plate 2216 contacts the bottom surface of the bed board 11, and the bottom surface of each limit block 2215 is fixedly connected to a second spring 2217. The end of each second spring 2217 away from the limit block 2215 contacts the inner bottom wall of the bed board 11. The second spring 2217 is located between the limit block 2215 and the bed board 11, so the rebound force of the second spring 2217 will push the limit block 2215 upward. At this time, the relationship between the limit plate 2216 and the limit rod 2214 is fixedly connected, and the limit plate 2216 has a large area and cannot pass through the bed board 11, so it will be blocked by the bed board 11, and the limit rod 2214 is limited to the height lifted by the second spring 2217, thereby ensuring that the limit block 2215 can be used to limit the rotating shaft 2201 to prevent the rotating shaft 2201 from falling off during use.

[0026] The specific implementation method of this embodiment is as follows: first, ensure that the tightening belt 2205 and the pulling rope 2207 are wound in opposite directions on the rotating shaft 2201. At this time, the staff member takes the buckle 2210 and pulls out the tightening belt 2205, and then inserts the buckle 2210 into the inside of the lock buckle 2212. At this time, the tightening belt 2205 is used to fix the patient's chest and thigh parts. Since one end of the tightening belt 2205 is fixedly connected to the inner wall of the rotating shaft 2201, and the rotating shaft 2201 is fixedly connected to one end of the torsion spring 2204, when the tightening belt 2205 is manually pulled out, the rotating shaft 2201 is driven to rotate. At this time, the rotating shaft 2201 is rotated and drives the torsion spring 2204 to store force, and then the tightening belt 2205 will have a traction force that is reset by the torsion spring 2204, ensuring that the tightening belt 2205 is in a straightened state. Since one end of the tension rope 2207 is also fixedly connected to the rotating shaft 2201, the tension rope 2207 is wound around the outer surface of the rotating shaft 2201 in circles before the staff pulls out the tension belt 2205. When the staff pulls out the tension belt 2205, the rotating shaft 2201 is driven to rotate accordingly. At this time, the winding direction of the tension rope 2207 is consistent with the rotation direction of the rotating shaft 2201. The directions are opposite, and then when the rotating shaft 2201 rotates forward, the pulling rope 2207 will be released, and when the rotating shaft 2201 rotates reversely, the pulling rope 2207 will be rolled up. At this time, the pulling rope 2207 is released, and under the influence of the counterweight 2208, the pulling rope 2207 moves vertically downward and approaches the fixed ring 2112. The pulling rope 2207 itself has a certain elasticity to adapt to the problem that patients of different body shapes use different lengths of the tightening belt 2205. At this time, the anti-detachment hook 2209 is connected to the fixed ring 2112 to achieve a protective tightening effect. If the road surface is bumpy at this time, after the buffer unit After filtering, Yuan 21 still has a certain amount of shaking. When the downward force of the bump ends, it will rebound upward due to the buffering effect. At this time, there is a distance difference between the top frame 2101 and the bottom frame 2102. At this time, the tension rope 2207 is stretched, and the stretched tension rope 2207 will drive the rotating shaft 2201 to rotate. At this time, the direction in which the rotating shaft 2201 is rotated is exactly the rotation direction of the recovery tightening belt 2205. At this time, the rebound force of the torsion spring 2204 can be used to retract the tightening belt 2205, so that the two tightening belts 2205 can be tightened during the bumpy rebound force, so as to tighten the patient's body and avoid secondary injury.

[0027] Example 3: Please refer to Figure 1-Figure 13 The present invention provides a technical solution: a safe transport device for critically ill patients. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The protection mechanism 3 is used in conjunction with the shock absorbing mechanism 2. The protection mechanism 3 is convenient for quickly switching between different transport modes and can meet the needs of different transport methods. The protection mechanism 3 has good effects in terms of safety and convenience.

[0028] As a further limitation of the protection mechanism 3 of the present invention, the protection mechanism 3 includes two protection plates 302, the outer surface of each protection plate 302 is rotatably connected to two rotating seats 301, wherein the outer surfaces of the two rotating seats 301 are fixedly connected to two limiting tubes 303, the outer surface of each protection plate 302 is provided with two limiting grooves 304, the back of each protection plate 302 is provided with two limiting holes 305, the outer surface of each protection plate 302 is slidably connected to a limiter 306, the bottom surface of each limiter 306 is fixedly connected to a plug rod 310, the outer surface of each plug rod 310 is slidably connected to the inner wall of the limiting tube 303, the inner bottom wall of each limiter 306 is fixedly connected to a third spring 309, and one end of each third spring 309 is fixedly connected to the inner top wall of the protection plate 302. By setting the protection mechanism 3, it is convenient to quickly switch between different transport modes, which can meet the needs of different transport modes, so that the transport device has better performance in terms of safety and convenience; The inner wall of each limiter 306 is slidably connected to a limit rod 307, and the outer surface of each limit rod 307 is fixedly connected to a fourth spring 308. Each fourth spring 308 is sleeved on the outer surface of the limit rod 307, and the limit rod 307 is pushed into the interior of the limiter 306 by the fourth spring 308. At this time, the limit rod 307 can be inserted into the two opened limit holes 305. When the limit rod 307 is pulled up and inserted into the lower limit hole 305, it is a safety mode after the fixed position. If the limit rod 307 is pulled up and inserted into the upper limit hole 305, it is a free rotation mode. At this time, the protective plate 302 will naturally fall perpendicular to the bed board 11 under the influence of gravity.

[0029] The specific implementation method of this embodiment is as follows: first, the limiter 306 is slid on the top of the protective plate 302, and the limit grooves 304 on both sides are used to limit the limiter 306 to ensure the stability of the limiter 306. At this time, the third spring 309 is located between the limiter 306 and the protective plate 302. When the limiter 306 is pulled up, the third spring 309 is also charged. By utilizing the relationship that the insertion rod 310 is fixedly connected to the bottom surface of the limiter 306, the limiter 306 can be moved while the insertion rod 310 is moved up and down. When the transfer device is in the state of being transferred, the protective plate 302 can be adjusted to an upright state. Specifically, the limiter 307 is pulled out from the inside of the limit hole 305 by pulling the limiter rod 307, and then the limiter 306 is slid with the other hand to move the limiter 306 to the position of another limit hole 305. At this time, the limiter rod 307 is released. The fourth spring 308 is used to push the limit rod 307 out and insert it into the other limit hole 305, so that the protective plate 302 can be rotated as a whole. When the protective plate 302 is rotated to an upright state, the limit rod 307 is pulled up again and the limiter 306 is lowered. At this time, the insertion rod 310 is used to insert the limit tube 303 with the opening upward, and then the limit rod 307 is loosened again. At this time, the fourth spring 308 is used again to push the limit rod 307 out and insert it into the lower limit hole 305 to achieve the purpose of making the protective plate 302 upright. The protective plates 302 on both sides play a role of safety protection to ensure that both sides are protected by the protective plates 302 during the transfer process. The protective plates 302 can also be adjusted to a mode parallel to the bed board 11 to extend the area of ​​the bed board 11. The protective plates 302 can also be adjusted to a vertical state to facilitate the transfer of patients to other medical equipment.
