Description

Technical Field

[0001] This invention relates to the field of assisted transport, and more specifically, to an assisted transport vehicle for the transfer of critically ill patients. Background Technology

[0002] Patients with unstable vital signs, rapidly changing condition, unstable or declining function of two or more organ systems, whose condition may endanger their lives are called critically ill patients.

[0003] When some patients experience the above conditions, their families usually transfer them to a more specialized hospital with better medical equipment for treatment. Therefore, it is necessary to transfer critically ill patients. During the transfer, medical equipment is needed to monitor the patient's condition in real time to ensure that the transfer is carried out smoothly.

[0004] However, in the current technology, when a patient is moved from the hospital's treatment room to an ambulance for transfer, the space on the hospital bed is limited, which makes it impossible to place many medical devices. As a result, medical staff need to manually retrieve these devices to assist in the transfer, which inconveniences the patient transfer process. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an assisted transport vehicle for critically ill patients.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A transfer cart for critically ill patients includes a movable plate body. Universal wheels are fixedly installed around the lower surface of the movable plate body, and a movable frame is fixedly installed in the middle of the upper surface of the movable plate body. A placement mechanism is provided on the surface of the movable frame for fixing auxiliary medical equipment. A connecting mechanism is provided on the top of the movable frame and on the side adjacent to the placement mechanism for connecting the movable frame to the resuscitation bed.

[0008] The placement mechanism includes a rotating rod that rotates on the outer surface of the movable frame. One end of the rotating rod is rotatably connected to a fixed plate. A stabilizing rod slides through the fixed plate on one side of the rotating rod. A stabilizing plate is fixedly installed at the end of the stabilizing rod away from the movable frame.

[0009] Furthermore, the placement mechanism also includes a first spring sleeved on the surface of the stabilizing rod away from the movable frame. The upper and lower surfaces of the fixed plate are provided with a first fixing seat and a second fixing seat. The movable frame is provided with symmetrical stabilizing grooves on one side of the fixed plate. The upper and lower surfaces of the fixed plate are provided with an expansion mechanism. The upper surface of the first fixing seat is provided with a first mounting mechanism, and the lower surface of the second fixing seat is provided with a second mounting mechanism.

[0010] Furthermore, the expansion mechanism includes shrinkage grooves formed on the upper and lower surfaces of the fixed plate. Separator plates are respectively provided on the upper and lower surfaces of the fixed plate, located on both sides of the two shrinkage grooves. A third fixed seat and a fourth fixed seat are respectively fixedly installed on the upper and lower surfaces of the separator plates. A placement groove is formed inside the movable frame, located above the fixed plate. A first magnet is fixedly installed on the surface of the fixed plate away from the movable frame.

[0011] Furthermore, the first and second fixing seats are located inside the shrinkage grooves on the upper and lower surfaces of the fixing plate, respectively. After the third fixing seat is rotated 90 degrees, it is located inside the placement groove. One end of the positioning pin is located on one side of the placement groove, and the two stabilizing grooves are located on the rotation path of the stabilizing rod.

[0012] Furthermore, the support mechanism includes four positioning plates fixed to the two sides adjacent to the fixed plate and the movable frame. Each of the four positioning plates has a positioning groove inside. Four positioning rods are symmetrically distributed inside the two partition plates and the movable frame at their adjacent ends. A second spring is fixedly installed at one end of each of the four positioning rods inside the partition plate. A push rod is slidably connected to the side of the four positioning plates away from the partition plate.

[0013] Furthermore, the connecting mechanism includes a fixed frame fixed to one end of the movable frame, a transmission plate slidably connected to the inner surface of the fixed frame, a threaded rod provided inside and through the transmission plate, the threaded rod being threadedly connected to the transmission plate, U-shaped plates symmetrically distributed on the upper surface of the transmission plate, a transmission rod rotatably passing through the interior of each of the two U-shaped plates, a connecting hook fixedly installed on the outer circular surface of each of the two transmission rods, and a reciprocating disc fixedly installed at one end of each of the two transmission rods located on one side of the U-shaped plate, a torsion spring sleeved on the outer surface of each of the two transmission rods, and a locking mechanism provided inside the transmission plate.

[0014] Furthermore, the locking mechanism includes a sliding plate that slides inside the transmission plate, a snap-fit ​​plate is fixedly installed at one end of the sliding plate, two snap-fit ​​grooves are opened inside the reciprocating disc, a third spring is fixedly installed on the surface of the sliding plate near the transmission plate, and a triggering mechanism is provided inside the transmission plate.

[0015] Furthermore, one end of the third spring is fixedly connected to the surface of the transmission plate, the sliding plate is L-shaped, the snap-fit ​​plate is located on one side of the reciprocating disc, and the two ends of the torsion spring are fixedly connected to the surfaces of the reciprocating disc and the U-shaped plate, respectively.

[0016] Furthermore, the triggering mechanism includes a pressing groove formed inside the transmission plate, a pressing block that slides and seals inside the pressing groove, a connecting plate that is fixedly installed on one side of the pressing block at its outer end, a fourth spring that is fixedly installed on the side of the connecting plate near the transmission plate, a reciprocating plate that slides and seals inside the pressing groove, a through groove that is formed inside the pressing block, and a one-way valve that is fixedly installed inside the pressing block, one end of the fourth spring that is fixed inside the transmission plate, one end of the sliding plate that is located inside the pressing groove, and the end of the sliding plate that is located inside the pressing groove that is fixedly connected to the surface of the reciprocating plate.

[0017] Furthermore, the first mounting mechanism includes a first mounting groove formed on the upper surface of the first fixed base. A fixing strap is fixedly mounted on the upper surface of the first fixed base and on one side of the first mounting groove, and a snap-fit ​​component is fixedly mounted on the upper surface of the first fixed base and on the other side of the first mounting groove. The second mounting mechanism includes a second mounting groove formed on the lower surface of the second fixed base.

Stabilizing blocks are fixedly installed on both the surface of the limiting frame near the first limiting block and the surface away from the first limiting block. The second fixing seat has a fixing slot communicating with the second mounting slot on both sides of its interior. A stabilizing plate is rotatably connected to the surface of the power supply away from the limiting frame. A moving slot matching and connected to the stabilizing plate is opened on the upper surface of the second fixing seat below one end of the power supply. One end of the fifth spring is located inside the limiting frame, which is U-shaped. One end of the stabilizing block is located inside the fixing slot and slidably connected to the inner surface of the fixing slot.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) This solution sets up a placement mechanism so that the positioning of the fixing plate can be released by pulling the stabilizing plate and then the fixing plate can be rotated so that two different fixing seats can be set on both sides of the fixing plate. Different fixing seats can be used to fix different instruments, thereby satisfying the fixing of different instruments and avoiding the problem that when facing different instruments, it is impossible to switch the fixing seats, resulting in only some instruments being fixed.

[0020] (2) This solution uses a rotatable partition plate on the fixed plate to allow different mounting seats to be installed on both sides of the partition plate. This allows different instruments to be installed before and after rotation, further increasing the adaptability to fixing different instruments.

[0021] (3) By setting up a support mechanism, when the fixed plate is in use, the two positioning rods below the fixed plate and away from the moving frame are pushed so that the positioning rods and positioning grooves are no longer stuck. Then the partition plate can be rotated so that the partition plate contacts the upper surface of the moving plate body, thereby completing the support of the fixed plate. This improves the stability of the fixed plate and increases its load-bearing capacity.

[0022] (4) This solution sets up a connecting mechanism. By rotating the connecting hook, the torsion spring is compressed. After rotation, under the action of the third spring, the snap plate enters the snap groove, completing the positioning of the connected hook after rotation. When the moving frame moves to one side of the bed, the snap plate is moved so that the snap plate and the snap groove are no longer snapped together. Then the torsion spring drives the connecting hook to connect with the bed, so that the moving frame moves synchronously with the bed. Then instruments or power supplies can be placed on the bed to assist in the treatment of the patient.

[0023] (5) This solution sets up a trigger mechanism to first move the mobile frame to one side of the bed, and then push the mobile frame so that the bed squeezes the compression block, which in turn causes the compression block to contract and squeeze the air inside the compression groove. This causes the air inside the compression groove to push the reciprocating plate, which causes the reciprocating plate to cause the snap plate to no longer snap with the snap groove, thus completing the automatic release of the connection hook positioning. The air inside the compression groove slowly flows out, causing the snap plate to slowly reset, thus repositioning the connection hook after rotation and improving the stability of the connection between the mobile frame and the bed.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Please see Figures 1 to 14 A transfer vehicle for critically ill patients includes a mobile plate body 1. Universal wheels 2 are fixedly installed around the lower surface of the mobile plate body 1, and a mobile frame 3 is fixedly installed in the middle of the upper surface of the mobile plate body 1. A placement mechanism 4 is provided on the surface of the mobile frame 3 for fixing auxiliary medical equipment. A connecting mechanism 5 is provided on the top of the mobile frame 3 and on the side adjacent to the placement mechanism 4 for connecting the mobile frame 3 to the resuscitation bed.

[0042] The placement mechanism 4 includes a rotating rod 41 that rotates on the outer surface of the movable frame 3. One end of the rotating rod 41 is rotatably connected to a fixed plate 42. A stabilizing rod 43 slides through the inside of the fixed plate 42 and on one side of the rotating rod 41. A stabilizing plate 44 is fixedly installed at the end of the stabilizing rod 43 away from the movable frame 3.

[0043] like Figure 1 - Figure 4 As shown, the placement mechanism 4 also includes a first spring 45 sleeved on the surface of the stabilizing rod 43 away from the movable frame 3. The upper and lower surfaces of the fixing plate 42 are provided with a first fixing seat 46 and a second fixing seat 47. The movable frame 3 is provided with a stabilizing groove 48 symmetrically on one side of the fixing plate 42. The upper and lower surfaces of the fixing plate 42 are provided with an extension mechanism 49. The upper surface of the first fixing seat 46 is provided with a first mounting mechanism 8, and the lower surface of the second fixing seat 47 is provided with a second mounting mechanism 9.

[0044] In actual use, different instruments are needed depending on the patient's condition, thus requiring different devices to be fixed. Since different devices have different shapes, different fixing structures are needed. Based on this, a placement mechanism 4 is set up. In the initial state, the first fixing seat 46 is located above the fixing plate 42, and the corresponding instrument can be fixed by the first fixing seat 46. When changing different instruments, the stabilizing plate 44 is pulled. The movement of the stabilizing plate 44 will drive the stabilizing rod 43 to move. The movement of the stabilizing rod 43 will cause the stabilizing rod 43 to no longer be engaged with the stabilizing groove 48. Then, the fixing plate 42 is rotated with the rotating rod 41 as the rotation center, so that the fixing plate 42 interchanges the positions of the first fixing seat 46 and the second fixing seat 47, thereby moving the second fixing seat 47 above the fixing plate 42, thus fixing different instruments.

[0045] like Figure 2 - Figure 5 As shown, the expansion mechanism 49 includes shrinkage grooves 491 formed on the upper and lower surfaces of the fixed plate 42. Partition plates 492 are respectively provided on the upper and lower surfaces of the fixed plate 42 and on both sides of the two shrinkage grooves 491. A third fixed seat 493 and a fourth fixed seat 494 are respectively fixedly installed on the upper and lower surfaces of the partition plates 492. A placement groove 495 is formed inside the movable frame 3 and above the fixed plate 42. A first magnet 496 is fixedly installed on the surface of the fixed plate 42 away from the movable frame 3. A second magnet 497 is fixedly installed on the surfaces of the two partition plates 492 away from the movable frame 3 and on one side of the first magnet 496. A positioning pin 498 is rotatably connected to the surface of the movable frame 3 above the placement groove 495. A support mechanism 499 is provided below the fixed plate 42.

[0046] The surfaces of the partition plate 492 and the fixing plate 42 are attached, and they can be rotated as needed in subsequent processes.

[0047] like Figure 1 - Figure 5 As shown, the first fixing seat 46 and the second fixing seat 47 are located inside the shrinkage groove 491 on the upper and lower surfaces of the fixing plate 42, respectively. The third fixing seat 493 is located inside the placement groove 495 after rotating ninety degrees. One end of the positioning pin 498 is located on one side of the placement groove 495. The two stabilizing grooves 48 are located on the rotation path of the stabilizing rod 43.

[0048] In practical use, the number of instruments that the placement mechanism 4 can fix is ​​limited, making it impossible to adaptably fix different instruments. Based on this, an extension mechanism 49 is set up. In the initial state, the third fixing seat 493 and the fixing plate 42 are kept parallel, so that the corresponding instrument can be fixed through the third fixing seat 493. When different instruments need to be fixed, the positioning pin 498 is rotated first so that the positioning pin 498 does not affect the rotation of the partition plate 492. Then the partition plate 492 is rotated so that the partition plate 492 enters the interior of the placement slot 495. After entering, the positioning pin 498 is rotated to reset, so that the positioning pin 498 positions the partition plate 492 inside the placement slot 495. Then, different instruments can be fixed through the fourth fixing seat 494 and the first fixing seat 46. Furthermore, the fixing plate 42 can also be rotated. After rotation, the above operations can also increase the fixing mechanism for different instruments.

[0049] like Figure 5 - Figure 8 As shown, the support mechanism 499 includes four positioning plates 4991 fixed to the two sides adjacent to the fixed plate 42 and the movable frame 3. Each of the four positioning plates 4991 has a positioning groove 4992 inside. Four positioning rods 4993 are symmetrically distributed inside the two partition plates 492 and the movable frame 3. A second spring 4994 is fixedly installed at one end of the four positioning rods 4993 inside the partition plate 492. A push rod 4995 is slidably connected to the side of the four positioning plates 4991 away from the partition plate 492.

[0050] In actual use, since one end of the fixed plate 42 is suspended, it is easy for the fixed plate 42 to be unstable when it shakes. Based on this, a support mechanism 499 is set up so that when the fixed plate 42 needs to be supported, the two push rods 4995 near the moving frame 3 are pushed, so that the push rods 4995 push the positioning rod 4993, so that the positioning rod 4993 is no longer located inside the positioning groove 4992. Then, under the action of gravity, the end of the partition plate 492 near the moving frame 3 rotates downward, so that one end of the partition plate 492 contacts the moving plate body 1, so that the partition plate 492 cooperates with the moving plate body 1 to support the fixed plate 42, thereby improving the stability and load-bearing capacity of the fixed plate 42.

[0051] like Figure 9 and Figure 10 As shown, the connecting mechanism 5 includes a fixed frame 51 fixed to one end of the movable frame 3. A transmission plate 52 is slidably connected to the inner surface of the fixed frame 51. A threaded rod 53 is provided inside and through the transmission plate 52. The threaded rod 53 is threadedly connected to the transmission plate 52. U-shaped plates 54 are symmetrically distributed on the upper surface of the transmission plate 52. A transmission rod 55 is rotatably inserted inside each of the two U-shaped plates 54. A connecting hook 56 is fixedly installed on the outer circular surface of each of the two transmission rods 55. A reciprocating disc 57 is fixedly installed at one end of each of the two transmission rods 55 located on one side of the U-shaped plate 54. A torsion spring 58 is sleeved on the outer surface of each of the two transmission rods 55. A locking mechanism 59 is provided inside the transmission plate 52.

[0052] In practical use, it is inconvenient to connect the mobile frame 3 to the hospital bed. Therefore, a connecting mechanism 5 is provided so that when it is necessary to connect the mobile frame 3 to the hospital bed, the connecting hook 56 is first rotated so that it is positioned above the transmission plate 52. When the connecting hook 56 is rotated, it will drive the transmission rod 55 to rotate. The rotation of the transmission rod 55 will drive the reciprocating plate 57 to rotate, which in turn will drive the torsion spring 58 to be in a compressed state. Then, the mobile frame 3 is moved to one side of the hospital bed railing. After the movement, the connecting hook 56 is no longer rotated. The pull mechanism drives the torsion spring 58 to rotate the reciprocating plate 57, which in turn drives the transmission rod 55 to rotate. The rotation of the transmission rod 55 drives the connecting hook 56 to rotate, causing the rotating connecting hook 56 to hang on the bed railing. This completes the connection between the bed and the mobile frame 3. Furthermore, when dealing with different beds, if the height of the bed railings is different, the threaded rod 53 can be rotated, causing the threaded rod 53 to drive the transmission plate 52 to move upward. This allows the moving transmission plate 52 to adjust the height of the connecting hook 56, thus meeting the needs of different beds.

[0053] like Figure 9 - Figure 11As shown, the locking mechanism 59 includes a sliding plate 591 that slides inside the transmission plate 52. A snap-fit ​​plate 592 is fixedly installed at one end of the sliding plate 591. Two snap-fit ​​grooves 593 are opened inside the reciprocating disc 57. A third spring 594 is fixedly installed on the surface of the sliding plate 591 near the transmission plate 52. A triggering mechanism 595 is provided inside the transmission plate 52.

[0054] like Figure 9 - Figure 11 As shown, one end of the third spring 594 is fixedly connected to the surface of the transmission plate 52, the sliding plate 591 is L-shaped, the snap-fit ​​plate 592 is located on one side of the reciprocating disc 57, and the two ends of the torsion spring 58 are fixedly connected to the surfaces of the reciprocating disc 57 and the U-shaped plate 54, respectively.

[0055] In actual use, when connecting the mobile frame 3 and the hospital bed, the connecting hook 56 needs to be continuously pulled, which makes the connection between the mobile frame 3 and the hospital bed inconvenient. Based on this, a locking mechanism 59 is set up so that when the connecting hook 56 is rotated, the reciprocating plate 57 will rotate. The rotation of the reciprocating plate 57 will drive the locking groove 593 to rotate. When the locking groove 593 rotates to one side of the locking plate 592, the third spring 594 pulls the sliding plate 591, so that the sliding plate 591 drives the locking plate 592 into the interior of the locking groove 593, thus completing the positioning of the connected hook 56 after rotation. When it is necessary to connect the mobile frame 3 and the hospital bed, it is only necessary to manually move the locking plate 592, which will release the positioning of the connected hook 56, allowing the connected hook 56 to rotate and complete the connection between the mobile frame 3 and the hospital bed.

[0056] like Figure 11 and Figure 12 As shown, the triggering mechanism 595 includes a pressing groove 5951 formed inside the transmission plate 52. A pressing block 5952 is slidably sealed inside the pressing groove 5951. A connecting plate 5953 is fixedly installed on one side of the pressing block 5952 at its outer end. A fourth spring 5954 is fixedly installed on the side of the connecting plate 5953 near the transmission plate 52. A reciprocating plate 5955 is slidably sealed inside the pressing groove 5951. A connecting groove 5956 is formed through the pressing block 5952. A one-way valve 5957 is fixedly installed inside the pressing block 5952. One end of the fourth spring 5954 is fixed inside the transmission plate 52. One end of the sliding plate 591 is located inside the pressing groove 5951, and the end of the sliding plate 591 located inside the pressing groove 5951 is fixedly connected to the surface of the reciprocating plate 5955.

[0057] The opening of the connecting groove 5956 is small, which means that the gas inside the extrusion groove 5951 needs a certain amount of time to flow out. The one-way valve 5957 is used to allow external air to enter the interior of the extrusion groove 5951.

[0058] In actual use, it is not possible to automatically connect the movable frame 3 and the bed when they come into contact with the bed railing. Therefore, a trigger mechanism 595 is set up. In the initial state, the locking plate 592 and the locking groove 593 engage, positioning the connecting hook 56 after rotation. The reciprocating plate 5955 is positioned in the middle of the compression groove 5951, near the sliding plate 591. Then, the movable frame 3 is moved to one side of the bed railing. After moving, the movable frame 3 is pushed towards the bed. At this time, the bed presses against the compression block 5952, causing it to contract inwards into the compression groove 5951. This results in the compression block 5952 pressing against the compression groove. The air inside 5951 is compressed, which pushes the reciprocating plate 5955. This causes the reciprocating plate 5955 to move the sliding plate 591. The movement of the sliding plate 591 causes the locking plate 592 to disengage from the locking groove 593, which in turn causes the connecting hook 56 to rotate and connect with the hospital bed. After the connecting hook 56 rotates, the gas inside the compression groove 5951 slowly flows out through the connecting groove 5956, preventing the air pressure from continuously pushing the reciprocating plate 5955. Then, the third spring 594 drives the sliding plate 591 and the locking plate 592 to reset, thus completing the positioning of the connected hook 56 after rotation and increasing the stability of the moving frame 3 after it is connected to the hospital bed.

[0059] like Figure 13 and Figure 14As shown, the first mounting mechanism 8 includes a first mounting groove 81 formed on the upper surface of the first fixed base 46. A fixing strap 82 is fixedly mounted on the upper surface of the first fixed base 46 and on one side of the first mounting groove 81, and a snap-fit ​​member 83 is fixedly mounted on the upper surface of the first fixed base 46 and on the other side of the first mounting groove 81. The second mounting mechanism 9 includes a second mounting groove 91 formed on the lower surface of the second fixed base 47. A limit frame 92 is slidably connected to the inner surface of the second mounting groove 91. A first limit block 93 is fixedly mounted on the opposite side of the limit frame 92. A mobile power supply 94 is provided on the upper surface of the second fixed base 47. A second limit block 95 is fixedly mounted on the surface of the mobile power supply 94 near the two first limit blocks 93. A fifth spring 96 is fixedly installed on the inner surface of the second mounting slot 91. Stabilizing blocks 97 are fixedly installed on both the surface of the limiting frame 92 near the first limiting block 93 and the surface away from the first limiting block 93. A fixing slot 98 communicating with the second mounting slot 91 is opened inside the second fixing seat 47 on both sides of the second mounting slot 91. A stabilizing plate 99 is rotatably connected to the surface of the mobile power supply 94 away from the limiting frame 92. A moving slot 910 matching and connected to the stabilizing plate 99 is opened on the upper surface of the second fixing seat 47 below one end of the mobile power supply 94. One end of the fifth spring 96 is located inside the limiting frame 92. The limiting frame 92 is U-shaped. One end of the stabilizing block 97 is located inside the fixing slot 98 and is slidably connected to the inner surface of the fixing slot 98.

[0060] When it is necessary to fix the oxygen tank by the first fixing seat 46, first disconnect one end of the fixing strap 82 from the snap fastener 83. After disconnection, place the oxygen tank inside the first mounting groove 81. Then, wrap the fixing strap 82 around the surface of the oxygen tank and connect it to the snap fastener 83. This will complete the fixation of the oxygen tank by the first fixing seat 46.

[0061] When the power bank 94 needs to be fixed by the second fixing seat 47, the limiting frame 92 is initially located inside the second mounting groove 91. Therefore, during use, the limiting frame 92 needs to be pulled. When the limiting frame 92 moves, it will drive the stabilizing block 97 to move. When the stabilizing block 97 moves to the top of the fixing groove 98, the limiting frame 92 is restricted by the stabilizing block 97 and the fixing groove 98 and cannot continue to move upward. Then, the power bank 94 to be installed is inserted from one end of the opening of the limiting frame 92. When inserted, the second limiting block 95 is located below the first limiting block 93. Then, the power bank 94 is continuously pushed. When the power bank 94 drives the stabilizing plate 99 to move above the moving groove 910, the stabilizing plate 99 is rotated so that one end of the stabilizing plate 99 enters the interior of the moving groove 910, thereby completing the fixing of the power bank 94.

[0062] For different mounting bases in the context, their surfaces are provided with buckles or connection ports or other installation structures that connect with specific instruments, so that different instruments can be installed. The above are examples of the first mounting base 46 and the second mounting base 47 using specific fixing structures for specific instruments. Other mounting bases can use different fixing mechanisms depending on the instrument they are fixing.

[0063] Instructions for use: First, push the two push rods 4995 on the side furthest from the two positioning rods 4993 of the movable frame 3, causing the push rods 4995 to disengage the positioning rods 4993 from the positioning grooves 4992. Then, rotate the partition plate 492 so that it enters the placement groove 495. Different instruments can then be fixed using different mounting brackets. Furthermore, pulling the stabilizing plate 44 will disengage the stabilizing rod 43 from the stabilizing groove 48. Finally, rotate the fixing plate 42 using the rotating rod 41 as a pivot. The rotating center of the circle causes the fixed plate 42 to flip, allowing different instruments to be fixed via different mounting seats at the bottom or top of the fixed plate 42. When supporting the instruments, the two positioning rods 4993 below the fixed plate 42 and near the movable frame 3 can be pushed, causing the partition plate 492 to rotate downwards under gravity, thus bringing the bottom end of the partition plate 492 into contact with the movable plate body 1 to support one end of the fixed plate 42. When connecting the movable frame 3 and the hospital bed, the connecting hook 56 is first rotated, causing the connecting hook 56 to rotate to the transmission position. Above the moving plate 52, as the connecting hook 56 rotates, the torsion spring 58 is compressed. After the connecting hook 56 rotates, the third spring 594 pulls the sliding plate 591, causing the sliding plate 591 to engage with the locking plate 592 and the locking groove 593, thus positioning the rotating connecting hook 56. When connecting the movable frame 3 to the hospital bed, the movable frame 3 is moved to one side of the hospital bed and then pushed, causing the hospital bed to press against the compression block 5952. This causes the compression block 5952 to retract into the compression groove 5951, thus closing the gap. During compression, the compression block 5952 compresses the air inside the compression groove 5951, causing the compressed gas to push the reciprocating plate 5955. This, in turn, causes the reciprocating plate 5955 to move the sliding plate 591 and the locking plate 592, so that the locking plate 592 is no longer locked to the locking groove 593. At this time, the connecting hook 56 is suspended from the bed under the action of the torsion spring 58. As the gas inside the compression groove 5951 overflows, the reciprocating plate 5955 slowly returns to its original position, allowing the locking plate 592 to enter the interior of another locking groove 593, thus completing the positioning of the rotating connecting hook 56.
