DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1:

[0031] See also Figure 1-7 The present invention provides a multifunctional bed for transporting injured persons in a lightweight shelter, comprising a storage box 1, a box plate 2 being hingedly connected to the front side wall of the storage box 1, and pillars 3 being rotatably connected to the inner walls of both sides of the storage box 1, and expansion slots 4 being penetrated through the outer walls of both sides of the storage box 1;

[0032] The inner wall of the storage box 1 is provided with a portable telescopic mechanism 5. Furthermore, the portable telescopic mechanism 5 also includes a rotating rod 501, and the outer wall of the rotating rod 501 is rotatably connected to the outer shell 502. The outer wall of the rotating rod 501 fits and slides with the inner wall of the expansion slot 4. The inner wall of the outer shell 502 is fixedly connected to the first bed board 504. The inner wall of the inner shell 503 is fitted with a second bed board 505 on one side of the inner wall facing the outer shell 502, and the side wall of the second bed board 505 close to the first bed board 504 is inclined. The inner walls of the inner shell 503 on both sides are provided with separation and combination grooves 506. The two side walls of the second bed board 505 are fixedly connected to support blocks 507 corresponding to the separation and combination grooves 506, and the outer wall of the support block 507 fits and slides with the inner wall of the separation and combination groove 506.

[0033] When the handle 510 is pulled outward, the outer wall of the rotating rod 501 is connected to the outer shell 502, and the outer wall of the rotating rod 501 slides against the inner wall of the expansion slot 4, and the inner walls of the two sides of the storage box 1 are connected to the support 3. When the handle 510 is pulled, the rotating rod 501 gradually slides upward from the lower inner wall of the expansion slot 4 under the restriction of the support 3, and the portable telescopic mechanism 5 rotates from the inside to the outside and from the vertical state to the horizontal direction. When the rotating rod 501 moves to the upper inner wall of the expansion slot 4, the portable telescopic mechanism 5 is in a horizontal state as a whole under the support of the support 3. At this time, the handle 510 is continued to be pulled outward.

[0034] At this time, the outer shell 502 cannot move outward further under the restriction of the expansion slot 4, so that the inner shell 503 slides outward from the telescopic slide slot 511. During this process, the first bed plate 504 is fixedly connected to the inner wall of the outer shell 502, and the inner shell 503 is provided with a second bed plate 505 on the inner wall facing the outer shell 502. The inner walls of the inner shell 503 are provided with separation and combination grooves 506 on both sides. At the same time, the two side walls of the second bed plate 505 are fixedly connected to the separation and combination grooves 506, and the outer wall of the support block 507 is fitted with the inner wall of the separation and combination groove 506, so that During the separation process, the support block 507 is first entirely in the upper inner wall of the separation groove 506, that is, at this time, the lower surface of the second bed board 505 slides on the upper surface of the first bed board 504. When it is pulled outward to the maximum distance, that is, at this time, the lower surface of the second bed board 505 is no longer in contact with the upper surface of the first bed board 504, the second bed board 505 moves downward under the action of gravity and is at the same level as the first bed board 504. At this time, the support block 507 is entirely in the lower inner wall of the separation groove 506, so that the first bed board 504 and the second bed board 505 are automatically spliced ​​together;

[0035] Then, a fixing rod 508 is threadedly connected to the outer wall of the inner shell 503 on the side away from the outer shell 502, corresponding to the separation groove 506, and one end of the fixing rod 508 is fixedly connected to the rotating handle 509, and the horizontal height of the fixing rod 508 corresponds to the upper inner wall of the separation groove 506. After the automatic splicing is completed, one hand keeps pulling the handle 510, and the other hand rotates the two rotating handles 509 respectively, so that the fixing rod 508 pushes into the upper inner wall of the separation groove 506 to limit the return height of the second bed board 505, so that the second bed board 505 cannot move up and return to its original position, thereby achieving fixation after splicing;

[0036] As described above, when the device is in use, the first bed board 504 and the second bed board 505 can be pulled out from the inside of the storage box 1 by pulling the handle 510 and automatically spliced ​​together to achieve rapid deployment of the cabin hospital. At the same time, when being transported or not in use, they can be stored in the storage box 1, which greatly reduces the occupation of transportation space and facilitates the handling and storage of the device, which is beneficial to improving the construction and relocation efficiency of the cabin hospital, thereby speeding up the rescue of the injured in the disaster-stricken area.

[0037] Embodiment 2, on the basis of the above embodiment, auxiliary shielding mechanisms 6 are provided on the outer walls of both sides of the storage box 1. Furthermore, the auxiliary shielding mechanism 6 includes a first rotating column 601, and one end portion of the two first rotating columns 601 close to each other is rotatably connected to the outer walls of both sides of the storage box 1, and the outer wall of the first rotating column 601 is fixedly connected to the second gear 602, and the lower side of the second gear 602 is meshed with the upper side of the first gear 513. The outer wall of the first rotating column 601 is rotatably connected to the transmission belt 603, and the inner wall of the other side of the transmission belt 603 is rotatably connected to the second rotating column 604, and one end portion of the second rotating column 604 is rotatably connected to the outer wall of one side of the storage box 1;

[0038] In this embodiment, when the rotating rod 501 moves to the upper inner wall of the expansion slot 4, the second gear 602 is fixedly connected through the outer wall of the first rotating column 601, and the lower side of the second gear 602 is meshed with the upper side of the first gear 513, so that when the portable telescopic mechanism 5 is in a horizontal state as a whole, the first gear 513 and the second gear 602 are meshed with each other. Then, when the inner shell 503 slides outward from the telescopic slide groove 511, a pull rope 512 is wrapped around the outer wall of the rotating rod 501, and the other end of the pull rope 512 is fixedly connected to the outer walls of the two ends of the inner shell 503, so that when the inner shell 503 slides outward, the first gear 513 can be driven to rotate through the pull rope 512, thereby synchronously driving the second gear 602 to rotate;

[0039] Then, a transmission belt 603 is rotatably connected to the outer wall of the first rotating column 601, and the inner wall of the other side of the transmission belt 603 is rotatably connected to the second rotating column 604, and one end of the second rotating column 604 is rotatably connected to the outer wall of one side of the storage box 1, so that the second rotating column 604 can be driven to rotate by the transmission belt 603. Then, a sliding rod 605 is fixedly connected to the outer wall of the second rotating column 604, and the outer wall of the sliding rod 605 close to the end of the second rotating column 604 is fixedly connected to a fixing ring 606, and the outer wall of the fixing ring 606 is fixedly connected to a curtain 607, and the other side of the curtain 607 is fixedly connected to a sliding ring 608. , and the inner wall of the slip ring 608 slides in contact with the outer wall of the slide bar 605, thereby synchronously driving the vertical slide bar 605 to rotate during the splicing process. When the splicing is completed, that is, when the pull rope 512 on the outer wall of the rotating rod 501 is pulled, the pulled pull rope 512 is used to limit the outward movement distance of the inner shell 503 to prevent the inner shell 503 and the outer shell 502 from separating from each other. At the same time, the vertical slide bar 605 will rotate to a horizontal state. At this time, the slip ring 608 can be freely moved to pull the curtain 607, and cooperate with the horizontal box board 2 to achieve comprehensive shielding around the bed, reducing the impact on the injured in the square cabin hospital;

[0040] Then, protrusions 609 are fixedly connected to the outer wall of the sliding rod 605 at equal distances corresponding to the slip ring 608, and the other end of the sliding rod 605 is fixedly connected to the slip ring 608. The protrusions 609 are made of rubber. Therefore, the position of the slip ring 608 can be limited by the protrusions 609, and the blocking range of the curtain 607 can be controlled without manual pulling. At the same time, the limit ring 610 limits the maximum sliding distance of the slip ring 608 to prevent the slip ring 608 from detaching from the sliding rod 605.

[0041] Furthermore, in a normal state, that is, when the first gear 513 and the second gear 602 are not engaged with each other, the slide bar 605 can be kept in a vertical downward direction under the action of gravity. That is, each time the slide bar 605 is rotated by engagement, the slide bar 605 can ultimately be kept at a substantially horizontal angle, so that the blind 607 can be stably deployed.

[0042] As described above, when the device is used, when the first bed board 504 and the second bed board 505 are spliced ​​together, the symmetrically arranged sliding rods 605 can be driven to rotate, and the curtains 607 can be installed and deployed, and cooperated with the opened box board 2 to achieve comprehensive shielding around the bed, reducing the impact on the injured in the square cabin hospital, which is conducive to improving the injured's recuperation in the square cabin hospital and accelerating the injured's recovery.

[0043] Embodiment 3, on the basis of the above embodiment, a storage groove 8 is opened at the bottom of the inner shell 503, and an auxiliary support mechanism 7 is provided on the inner wall of the storage groove 8. Furthermore, the auxiliary support mechanism 7 includes a support rod 701, and the outer wall of the support rod 701 slides in contact with the inner wall of the storage groove 8, and the same end of the two support rods 701 is fixedly connected to the universal wheel 702, and the other same end of the two support rods 701 is fixedly connected to the inside of the connecting rod 703, and the two ends of the connecting rod 703 are rotatably connected to the inner wall of the storage groove 8;

[0044] When the folding frame 514 is in the upright position, the support rod 701 is rotated to rotate with the support rod 702.

[0045] Then, when the support rod 701 is rotated to a vertical angle, the fixing rod 508 is used to push into the upper inner wall of the separation groove 506. At this time, the second bed board 505 is at the same level as the first bed board 504. At this time, the square cross bar 705 is fixedly connected to the outer wall of the connecting rod 703, and the upper surface of the square cross bar 705 is at the same height as the lower surface of the first bed board 504. As a result, the lower surface of the second bed board 505 is in contact with the upper surface of the square cross bar 705, so as to achieve the current angle of the support rod 701. Fixation ensures the stability of the device during use;

[0046] Then, when it is necessary to store it, first pull the handle 510 with one hand, then select the fixing rod 508 from the separation groove 506, at this time the second bed board 505 can be moved back to its position, and then press one of the support rods 701 with the other hand, and press the two support rods 701 back into the storage groove 8 at the same time, and then use the handle 510 to push the inner shell 503 back into the outer shell 502. At this time, the side wall of the second bed board 505 close to the first bed board 504 is in the shape of an inclined surface, so that under the guidance of the inclined surface, the second bed board 505 automatically slides to the upper surface of the first bed board 504, and the telescopic slide groove 511 is used to restrict the support rod 701. At this time, you can concentrate on pushing the inner shell 503 back to its original position with both hands. When the inner shell 503 is fully pushed into the outer shell 502, the inner walls on both sides of the outer shell 502 correspond to the support blocks 507 and the inner walls on both sides of the outer shell 502 correspond to the connection rods 703. There are installation grooves 9, 11, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103,

[0047] Furthermore, a circular groove 514 is correspondingly formed on the inner wall of the telescopic slide 511, and another torsion spring 704 is provided in the circular groove 514. The two ends of the other torsion spring 704 are respectively overlapped with the rotating rod 501 and the circular groove 514. Therefore, when the device is initially used, the handle 510 can be pulled by the other torsion spring 704 to drive the portable telescopic mechanism 5 to rotate from the inside to the outside and from the vertical state to the horizontal direction. When the device is subsequently stored, the other torsion spring 704 can be used to rewind the pull rope 512 for the next use.

[0048] As described above, when the device is in use, when the first bed board 504 and the second bed board 505 are spliced ​​together, the torsion spring 704 can be used to drive the two support rods 701 to automatically rotate, so as to achieve further support for the bed, and when the first bed board 504 and the second bed board 505 are subsequently fixed, the two support rods 701 can be automatically fixed synchronously, which is beneficial to improve the stability of the device when in use, and thereby ensure the stability of the injured person during sleep recovery and transfer treatment.

[0049] Working principle: First, when using the device, the four universal wheels 702 at the bottom of the storage box 1 are used to fix the foot brake, then the hinged box board 2 is opened, and then the handle 510 is pulled outward. Under the restriction of the support 3, the rotating rod 501 gradually slides upward from the lower inner wall of the expansion slot 4, and at this time, the portable telescopic mechanism 5 as a whole rotates from the inside to the outside and from the vertical state to the horizontal direction. When the rotating rod 501 moves to the upper inner wall of the expansion slot 4, the portable telescopic mechanism 5 as a whole is in a horizontal state under the support of the support 3. At this time, the handle 510 continues to be pulled outward;

[0050] At this time, the inner shell 503 slides outward from the telescopic slide groove 511. During the separation process, the support block 507 is first entirely in the upper inner wall of the separation groove 506, that is, the lower surface of the second bed board 505 slides on the upper surface of the first bed board 504. When it is pulled outward to the maximum distance, that is, the lower surface of the second bed board 505 is no longer in contact with the upper surface of the first bed board 504, the second bed board 505 moves downward under the action of gravity and is at the same level as the first bed board 504. At this time, the support block 507 is entirely in the lower inner wall of the separation groove 506, so that the first bed board 504 and the second bed board 505 are automatically spliced ​​together;

[0051] After the automatic splicing is completed, one hand keeps pulling the handle 510, and the other hand rotates the two knobs 509 respectively, so that the fixing rod 508 is pushed into the upper inner wall of the separation groove 506 to limit the return height of the second bed board 505, so that the second bed board 505 cannot move up and return to its original position, thereby achieving the fixation after splicing;

[0052] Then, during the splicing process, the vertical slide bar 605 will be synchronously driven to rotate. When the splicing is completed, that is, when the pull rope 512 on the outer wall of the rotating rod 501 is pulled, the pulled pull rope 512 is used to limit the outward movement distance of the inner shell 503 to prevent the inner shell 503 and the outer shell 502 from separating from each other. At the same time, the vertical slide bar 605 will rotate to the horizontal state. At this time, the sliding ring 608 can be freely moved to pull the curtain 607, and cooperate with the horizontal box board 2 to achieve comprehensive shielding around the bed.

[0053] Then, during the splicing process, the support rod 701 maintains a horizontal angle under the restriction of the telescopic slide 511. When the splicing is completed, the storage slot 8 will be fully displayed. At this time, the support rod 701 is no longer blocked by the telescopic slide 511, and the connecting rod 703 is driven to rotate through the torsion spring 704, so that the two support rods 701 are rotated synchronously from a horizontal angle to a vertical angle, so as to utilize the universal wheel 702 to further support the bed.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
