Specific embodiments

[0029] Next, each embodiment of the present invention will be described in detail with reference to Figures 1 to 10 Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0030] First embodiment: A civilian first aid transfer device, as Figures 1 - 4As shown in the figure, it includes a bed frame 1 and a bed board 2. Telescopic rods for guiding are vertically arranged at the head and tail of the bed frame 1. A support plate 5 is fixedly connected to the free end of the telescopic rod. A U-shaped plate 6 is arranged directly below the support plate 5. The free end of the telescopic rod is slidably connected through the U-shaped plate 6. The U-shaped plate 6 is located above the inner bottom wall of the bed frame 1, and a first spring 7 is installed between the two. The first spring 7 is a compression spring. The number of telescopic rods is multiple. The telescopic rod includes a sleeve 3 arranged on the inner bottom wall of the bed frame 1. A guide post 4 is slidably fitted in the sleeve 3. Positioning rings 14 are fixedly connected to both the support plate 5 and the U-shaped plate 6. The positioning ring 14 on the support plate 5 is fixedly connected to the top end of the guide post 4. The positioning ring 14 on the U-shaped plate 6 is slidably connected through the guide post 4. Long card slots 13 are opened at both ends of the bed board 2. The bed board 2 is placed on the top of the support plate 5, and a card block 38 matching the long card slot 13 is arranged on the top of the support plate 5.

[0031] In this embodiment, the top of the U-shaped plate 6 abuts against the bottom of the support plate 5. When the device moves, affected by factors such as uneven road surfaces, the vibration or shaking on the bed frame 1 will be transmitted to the bed board 2. Through the fact that the guide post 4 can slide in the sleeve 3 and the positioning ring 14 on the U-shaped plate 6 can slide along the guide post 4, the support plate 5 and the U-shaped plate 6 can move up and down. Coupled with the setting of the first spring 7, it can play a shock-absorbing effect, thereby improving the comfort of the patient during transportation.

[0032] Second embodiment: As Figure 2 shown, based on the fact that the bed board 2 in the first embodiment is shock-absorbed by the first spring 7 to improve the comfort of the patient during transportation. However, when the road surface pothole degree is relatively serious, the bed board 2 will have serious up and down shaking, and the patient will feel uncomfortable. And moving at high speed in this state, there is a risk that the patient or the first aid equipment on the bed body will fall. Therefore, in view of the above problems, the device in this embodiment has the following improvements: As Figures 1 - 4 and Figure 6 shown, a first electromagnet 8 and a second electromagnet 9 are respectively installed on the bottom of the support plate 5 and the top of the U-shaped plate 6. A resistance strip 10 and a first electrode block 11 are arranged on the inner bottom wall of the bed frame 1. A second electrode block 12 is arranged on the U-shaped plate 6. Both the first electrode block 11 and the second electrode block 12 are in contact with the resistance strip 10. Both the first electromagnet 8 and the second electromagnet 9 are electrically connected to the second electrode block 12. A second spring 15 is installed between the support plate 5 and the U-shaped plate 6. The second spring 15 is a tension spring.

[0033] In this embodiment, the first electromagnet 8 and the second electromagnet 9 are in a magnetically repulsive state. When the device in this embodiment moves, affected by factors such as uneven road surfaces, the device is buffered by the first spring 7, and the U-shaped plate 6 moves up and down during the movement of the device. It should be noted that when the U-shaped plate 6 descends, the second electrode block 12 follows the U-shaped plate 6 and descends, causing the resistance strip 10 between the first electrode block 11 and the second electrode block 12 to shorten, that is, increasing the current intensity on the first electromagnet 8 and the second electromagnet 9, and increasing the magnetic repulsive force between the first electromagnet 8 and the second electromagnet 9, increasing the distance between the support plate 5 and the U-shaped plate 6, and the support plate 5 abuts against the bed board 2 to rise to compensate for the distance that the U-shaped plate 6 brings the bed board 2 down; when the U-shaped plate 6 rises, the second electrode block 12 follows the U-shaped plate 6 and rises, causing the resistance strip 10 between the first electrode block 11 and the second electrode block 12 to lengthen, that is, reducing the current intensity on the first electromagnet 8 and the second electromagnet 9, and reducing the magnetic repulsive force between the first electromagnet 8 and the second electromagnet 9, reducing the distance between the support plate 5 and the U-shaped plate 6 to correspond to the distance that the U-shaped plate 6 brings the bed board 2 up; during the movement of the device in this embodiment, while being buffered by the first spring 7, the distance between the support plate 5 and the U-shaped plate 6 can be adjusted independently, so that the height of the bed board 2 is always kept close to being consistent, preventing the bed board 2 from shaking up and down greatly and making the patient feel uncomfortable, and avoiding the patient or the first-aid equipment on the bed body from falling due to large-scale up and down shaking.

[0034] As Figures 2 - 4 , Figure 6 and Figure 7 shown, two mounting plates are provided on the inner bottom wall of the bed frame 1, and the two mounting plates are respectively arranged near the head and the tail of the bed frame 1. Vertical sliding grooves 16 are formed on the mounting plates, and first sliders 18 are slidably fitted in the vertical sliding grooves 16. The first sliders 18 are fixedly connected to the first electrode blocks 11; a horizontal sliding groove 17 is formed on one side of the vertical sliding groove 16 on the mounting plate, and a second slider 39 is slidably fitted in the horizontal sliding groove 17. A counterweight block 19 is fixedly connected to the second slider 39. Through the cooperation of the horizontal sliding groove 17 and the second slider 39, the counterweight block 19 can move along the direction of the horizontal sliding groove 17. One end of the counterweight block 19 is conical, and the conical end of the counterweight block 19 is matched with the first slider 18. A third spring 20 is installed between the side of the second slider 39 away from the first slider 18 and the inner wall of the horizontal sliding groove 17. The third spring 20 is a tension spring.

[0035] When the device moves on an uphill section (for example, when the device is transported to an ambulance through a ramp platform, etc.), one side of the bed frame 1 inclines downward. The counterweight 19 near the lower part of the bed frame 1 slides along the transverse chute 17 and approaches the first slider 18. At the same time, the third spring 20 stretches to store energy. The conical end of the counterweight 19 abuts against the corresponding first slider 18, causing the first slider 18 to move upward along the vertical chute 16. The corresponding first electrode block 11 rises, shortening the resistance strip 10 between it and the second electrode block 12. That is, the current intensity on the first electromagnet 8 and the second electromagnet 9 increases, and the magnetic repulsive force between the first electromagnet 8 and the second electromagnet 9 increases. The distance between the corresponding support plate 5 and the U-shaped plate 6 increases. It should be noted that the block 38 can move within the long chute 13. The support plate 5 rises and jacks up the downward-inclined side of the bed frame 1, making the bed frame 1 close to a horizontal state. When the device moves on an uphill section, the bed frame 1 is close to a horizontal state, avoiding a large inclination of the bed frame 1 to one side, which may cause discomfort to the patient and prevent the possibility of the patient or the first aid equipment on the bed from falling.

[0036] When the device moves to a horizontal section again, the third spring 20 releases its force and pulls the counterweight 19 back to its original position. The corresponding first electrode block 11 descends and resets. The magnetic repulsive force between the first electromagnet 8 and the second electromagnet 9 decreases, and the support plate 5 and the bed frame 1 reset.

[0037] Third Embodiment: Based on the second embodiment, as Figure 2 、 Figure 3 and Figure 5 shown, a guide groove 21 is provided at the bottom of the bed frame 1. A positioning block 22 is slidably fitted in the guide groove 21. A soft pad is provided at the bottom of the positioning block 22, which can increase the friction between the positioning block 22 and the ground. A pedal 23 and a bracket are provided on the positioning block 22 outside the guide groove 21. A fourth spring 24 is installed between the bracket and the bottom of the bed frame 1. The fourth spring 24 is a tension spring. The top of the positioning block 22 is fixedly connected to a lifting rod 25. The lifting rod 25 is slidably connected through the bottom wall of the bed frame 1. The top of the lifting rod 25 is fixedly connected to a limit block 26. The limit block 26 is provided in a frustum shape and is made of a metal with a certain flexibility.

[0038] As Figure 2 、 Figure 3 、 Figure 5 and Figure 8 shown, the sleeve 3 near the lifting rod 25 is rotatably connected through the bottom wall of the bed frame 1. A blocking block 27 is fixedly connected to the sleeve 3, and an adjusting handle 28 is fixedly connected to its bottom end. The limit block 26 matches the blocking block 27. A torsion spring 29 is sleeved on the sleeve 3 between the bottom wall of the bed frame 1 and the blocking block 27.

[0039] When it is necessary to lock the position of the device, for example, the device is located in an ambulance, the pedal 23 is stepped on to descend, the positioning block 22 descends and is pulled out of the guide groove 21, and at the same time the fourth spring 24 is stretched to store force, and the lifting rod 25 follows the positioning block 22 to descend. It should be noted that through the coordinated arrangement of the limit block 26 and the blocking block 27, when the limit block 26 follows the lifting rod 25 to descend, the blocking block 27 will not block the limit block 26 from descending. When the positioning block 22 descends to its bottom and contacts the bottom wall of the ambulance compartment, the limit block 26 passes over the blocking block 27. At this time, the pedal 23 is released, and the blocking block 27 blocks the limit block 26, so that the fourth spring 24 cannot release force to reset the positioning block 22, that is, the position of the positioning block 22 is locked, and the positioning block 22 contacts the bottom wall of the ambulance compartment, thereby improving the stability of the device during the driving of the ambulance.

[0040] When the device needs to be unlocked, the adjusting handle 28 is rotated forward, the sleeve 3 connected with the blocking block 27 is rotated forward, and at the same time the torsion spring 29 accumulates force, the blocking block 27 rotates forward and no longer blocks the limit block 26, and the fourth spring 24 releases the force to pull the positioning block 22 up, thereby unlocking the device.

[0041] After the positioning block 22 is lifted up and reset with the lifting rod 25 and the limit block 26, the adjusting handle 28 is released, the torsion spring 29 releases the force and causes the blocking block 27 to rotate in the opposite direction to reset.

[0042] like Figure 3 , Figures 8 - 10 As shown, the top of the sleeve 3 connected to the blocking block 27 is rotatably connected to the driving ring 30, and a push block 31 is fixedly connected to the driving ring 30, and a receiving block 37 matching the push block 31 is fixedly connected to the sleeve 3 connected to the blocking block 27; a key block 32 is fixedly connected to the inner wall of the driving ring 30, and a key slot 33 is longitudinally opened on the guide column 4 close to the blocking block 27, and the key block 32 and the key slot 33 are slidably matched.

[0043] A protrusion 34 is fixedly connected to the inner wall of the positioning ring 14 on the U-shaped plate 6 and close to the blocking block 27, and a V-shaped groove 35 is provided on the guide column 4 close to the blocking block 27. The top and bottom ends of the V-shaped groove 35 are connected to the inside of the key groove 33, and the key groove 33 and the V-shaped groove 35 are matched with the protrusion 34. A guide piece 36 is hinged at the top of the V-shaped groove 35, and the guide piece 36 can only rotate upward.

[0044] In this embodiment, when the first electromagnet 8 and the second electromagnet 9 are energized, the first electromagnet 8 and the second electromagnet 9 magnetically repel each other, causing the support plate 5 to move away from the U-shaped plate 6. At the same time, the protrusion 34 slides downward along the key groove 33. Through the arrangement of the guide piece 36, when the support plate 5 starts to move away from the U-shaped plate 6, when the protrusion 34 moves to contact the upper surface of the guide piece 36, the protrusion 34 slides along the upper surface of the guide piece 36 into the V-shaped sliding groove 35 and finally re-enters the key groove 33 from the bottom end of the V-shaped sliding groove 35. It should be noted that during the sliding process of the protrusion 34 in the V-shaped sliding groove 35, the corresponding guide post 4 makes a round of reciprocating rotation. Then, by the cooperation of the key block 32 and the key groove 33, that is, the driving ring 30 rotates reciprocally following the guide post 4. When the driving ring 30 rotates forward, the push block 31 rotates forward and pushes the receiving block 37, thereby causing the corresponding sleeve 3 to rotate forward, that is, the blocking block 27 rotates forward. If the positioning block 22 is in the extended state at this time (the device is in the locked state), the forward rotation of the blocking block 27 no longer blocks the limiting block 26, and the positioning block 22 automatically rises, releasing the lock of the device. That is, when the device in this embodiment needs to be in a movable state, the first electromagnet 8 and the second electromagnet 9 are energized. While the function of automatically adjusting the distance between the support plate 5 and the U-shaped plate 6 is turned on, the positioning block 22 will automatically rise, eliminating the need for the rescue personnel to spend extra time unlocking the device and saving more time for first aid work.

[0045] When the first electromagnet 8 and the second electromagnet 9 are de-energized, the support plate 5 moves closer to the U-shaped plate 6. At the same time, the protrusion 34 slides upward along the key groove 33. When the protrusion 34 moves to abut against the bottom of the guide piece 36, the protrusion 34 abuts against the guide piece 36 to cause the guide piece 36 to flip upward. The guide piece 36 does not block the movement of the protrusion 34, and the protrusion 34 finally moves to the top end of the key groove 33.

[0046] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0047] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components.
