Detailed embodiments

[0032] 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.

[0033] First embodiment:

[0034] 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 both the head and the 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.

[0035] 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. The guide post 4 can slide in the sleeve 3, 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.

[0036] Second Embodiment:

[0037] As Figure 2 shown, based on the fact that the bed board 2 is shock-absorbed by the first spring 7 in the first embodiment to improve the comfort of the patient during transportation, but when the road surface pothole degree is relatively serious, the bed board 2 will shake severely up and down, the patient will feel uncomfortable, and when moving at high speed in this state, there is a risk of the patient or the first aid equipment on the bed body falling. Therefore, in view of the above problems, the device in this embodiment has been improved as follows:

[0038] 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. The first electrode block 11 and the second electrode block 12 are both in contact with the resistance strip 10. The first electromagnet 8 and the second electromagnet 9 are both 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.

[0039] 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. During the movement of the device, the U-shaped plate 6 moves up and down. It should be noted that when the U-shaped plate 6 descends, the second electrode block 12 follows the U-shaped plate 6 downwards, shortening the resistance strip 10 between the first electrode block 11 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, increasing the distance between the support plate 5 and the U-shaped plate 6. The support plate 5 abuts against the bed board 2 to rise to compensate for the distance that the U-shaped plate 6 drives the bed board 2 to descend; when the U-shaped plate 6 rises, the second electrode block 12 follows the U-shaped plate 6 upwards, lengthening the resistance strip 10 between the first electrode block 11 and the second electrode block 12. That is, the current intensity on the first electromagnet 8 and the second electromagnet 9 decreases, and the magnetic repulsive force between the first electromagnet 8 and the second electromagnet 9 decreases, 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 drives the bed board 2 to rise; 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.

[0040] 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. The two mounting plates are respectively arranged near the head and the tail of the bed frame 1. Vertical chutes 16 are formed on the mounting plates. A first slider 18 is slidably fitted in the vertical chutes 16. The first slider 18 is fixedly connected to the first electrode block 11; a horizontal chute 17 is formed on one side of the vertical chute 16 on the mounting plate. A second slider 39 is slidably fitted in the horizontal chute 17. A counterweight 19 is fixedly connected to the second slider 39. Through the cooperation of the horizontal chute 17 and the second slider 39, the counterweight 19 can move along the direction of the horizontal chute 17. One end of the counterweight 19 is conical, and the conical end of the counterweight 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 chute 17. The third spring 20 is a tension spring.

[0041] When the device moves on an uphill section (for example, when the device is transported to an ambulance through a ramp), one side of the bed frame 1 tilts downward. The counterweight 19 near the bottom 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-tilting 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, preventing the bed frame 1 from tilting significantly to one side, causing discomfort to the patient, and preventing the possible fall of the patient or the first aid equipment on the bed body.

[0042] 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 are reset.

[0043] Third Embodiment:

[0044] 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.

[0045] 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 the bottom end of the sleeve 3. 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.

[0046] When it is necessary to lock the position of this device, for example, when this device is located in an ambulance, the pedal 23 is stepped on and lowered, the positioning block 22 is lowered and 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 coordination 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 the 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.

[0047] When the device needs to be unlocked, the adjusting handle 28 is rotated forward, the sleeve 3 connected to 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 releasing the lock of the device.

[0048] 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.

[0049] 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 slides in conjunction with the key slot 33.

[0050] 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. 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.

[0051] 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 to make the support plate 5 move away from the C-shaped plate 6, and at the same time, the protrusion 34 slides downward along the key groove 33. Through the setting of the guide piece 36, when the support plate 5 moves away from the C-shaped plate 6, the protrusion 34 moves to the upper surface of the contact guide piece 36, and the protrusion 34 slides along the upper surface of the guide piece 36 to the inside of the V-shaped groove 35, and finally re-enters the key groove 33 from the bottom end of the V-shaped groove 35. It should be noted that during the sliding process of the protrusion 34 in the V-shaped groove 35, the corresponding guide column 4 performs a round of reciprocating rotation, and then the key block 32 and the key groove 33 are matched to each other, that is, the drive ring 30 follows the guide When the column 4 rotates back and forth and the drive 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 (the device is in the locked state) at this time, the blocking block 27 rotates forward and no longer blocks the limit block 26. The positioning block 22 automatically rises to release the lock of the device. That is, when the device in this embodiment needs to be moved, the first electromagnet 8 and the second electromagnet 9 are energized, and the function of automatically adjusting the distance between the support plate 5 and the C-shaped plate 6 is turned on. At the same time, the positioning block 22 automatically rises, and the rescue personnel do not need to spend extra time to release the lock of the device, saving more time for first aid work.

[0052] When the first electromagnet 8 and the second electromagnet 9 are powered off, the support plate 5 moves close to the C-shaped plate 6, and the protrusion 34 slides upward along the key slot 33. When the protrusion 34 moves to the bottom of the guide piece 36, the protrusion 34 hits the guide piece 36 to flip the guide piece 36 upward. The guide piece 36 will not block the movement of the protrusion 34, and the protrusion 34 eventually moves to the top of the key slot 33.

[0053] It should be noted that in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings.
