[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 with a 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 in an inclined shape, the inner walls of both sides of the inner shell 503 are provided with separation and combination grooves 506, and the two side walls of the second bed board 505 are fixedly connected with 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] In this embodiment, when using the device, the storage box 1 is first fixed by the foot brake through the four universal wheels 702 at the bottom, and then the hinged box board 2 is opened. At this time, the portable telescopic mechanism 5 inside is in a vertical state as a whole, and then the handle 510 is pulled outward. At this time, the outer wall of the rotating rod 501 is rotatably connected to the shell 502, and the outer wall of the rotating rod 501 slides with the inner wall of the expansion slot 4, and the inner walls of the two sides of the storage box 1 are rotatably connected to the pillars 3, so that 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 pillars 3, and the portable telescopic mechanism 5 rotates from the inside to the outside and from the vertical state to the horizontal direction as a whole. 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 pillars 3, and the handle 510 continues to be pulled outward;

[0034] At this time, the outer shell 502 cannot continue to move outward under the restriction of the expansion slot 4, so that the inner shell 503 slides outward from the telescopic slide slot 511. In this process, the first bed plate 504 is fixedly connected through 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 of one side facing the outer shell 502, and the inner walls of the inner shell 503 on both sides are provided with separation grooves 506.

When it is pulled outward to the maximum distance, that is, at this time, the lower surface of the second bed board 505 is not in contact with the upper surface of the first bed board 504, at this time, under the action of gravity, the second bed board 505 moves downward and is at the same horizontal height 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;

[0035] Then, a fixing rod 508 is threadedly connected to the outer wall of the inner shell 503 on one side away from the outer shell 502, corresponding to the separation groove 506, and a rotary handle 509 is fixedly connected to one end of the fixing rod 508, 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 rotary 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 be moved up and returned, 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 storage box 1 and automatically spliced ​​by pulling the handle 510, so as to realize the 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, and further, 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 and matched with the upper side of the first gear 513, and the outer wall of the first rotating column 601 is rotatably connected to the transmission belt 603, and the inner wall on 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 is displaced 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 and matched 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, and then when the inner shell 503 slides outward from the telescopic slide groove 511, a pull rope 512 is wound 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 pull rope 512 can drive the first gear 513 to rotate, and then synchronously drive the second gear 602 to rotate;

[0039] Then, the transmission belt 603 is rotatably connected to the outer wall of the first rotating column 601, and the inner wall on 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 body 1, so that the second rotating column 604 can be driven to rotate by the transmission belt 603, and then the 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 the fixing ring 606, and the outer wall of the fixing ring 606 is fixedly connected to the blind 607, and the other side of the blind 607 is fixedly connected to the sliding ring 608 , and the inner wall of the slip ring 608 slides in contact with the outer wall of the slide bar 605, so that during the splicing process, the slide bar 605 in the vertical state 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 from being separated from the outer shell 502. At the same time, the slide bar 605 in the vertical state will rotate to a horizontal state, and 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, a protrusion 609 is fixedly connected to the outer wall of the sliding rod 605 at an equal distance corresponding to the slip ring 608, and the other end of the sliding rod 605 is fixedly connected to the slip ring 608 corresponding to the slip ring 608, and the protrusion 609 is made of rubber, so that the position of the slip ring 608 can be limited by a plurality of protrusions 609, and the shielding range of the blind 607 can be controlled without manual pulling. At the same time, the limit ring 610 is used to limit 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 meshed 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 meshed to rotate, the slide bar 605 can eventually 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, the symmetrically arranged sliding rods 605 can be driven to rotate, and the curtains 607 can be installed and deployed, and cooperate with the opened box board 2 to achieve comprehensive shielding around the bed, thereby reducing the impact on the injured in the square cabin hospital, which is conducive to improving the recovery of the injured in the square cabin hospital and accelerating the recovery of the injured.

[0043] Embodiment 3, on the basis of the above embodiment, a storage groove 8 is provided 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. Further, 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 a universal wheel 702, and the other same end of the two support rods 701 is fixedly connected to a 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] In this embodiment, first, during the splicing process, the storage slot 8 is not fully displayed, that is, the support rod 701 maintains a horizontal angle under the restriction of the telescopic slide slot 511. When the splicing is completed, the storage slot 8 will be fully displayed, and the support rod 701 is no longer blocked by the telescopic slide slot 511. The universal wheel 702 is fixedly connected to the same end of the two support rods 701, 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 slot 8. At the same time, a torsion spring 704 is provided on the outer wall of the connecting rod 703, and one end of the torsion spring 704 is overlapped on the outer wall of the connecting rod 703, and the other end of the torsion spring 704 is overlapped on one side of the inner wall of the inner shell 503, so that the connecting rod 703 can be driven to rotate by the torsion spring 704, so that the two support rods 701 are synchronously rotated from a horizontal angle to a vertical angle, so as to further support the bed with the universal wheel 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, and the second bed board 505 is at the same horizontal height 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, so that 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 fix the current angle of the support rod 701 and ensure the stability of the device when in 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 use both hands to push the inner shell 503 back to its original position. When the inner shell 503 is fully pushed into the outer shell 502, the inner walls on both sides of the outer shell 502 are provided with mounting grooves 9 corresponding to the support blocks 507, and the inner walls on both sides of the outer shell 502 are provided with mounting grooves 11 corresponding to the connecting rods 703, so that after the inner shell 503 is fully pushed into the outer shell 502, the support blocks 507 will be pushed into the mounting grooves 1 9, and the connecting rods 703 will be pushed into the mounting grooves 2 11. Then, hold one end of the handle 510 and push it upward and inward. Under the guidance of the pillar 3, the portable telescopic mechanism 5 is stored back into the storage box 1 as a whole to complete the entire use process.

[0047] Furthermore, a circular groove 514 is correspondingly provided on the inner wall of the telescopic slide groove 511, and another torsion spring 704 is provided in the circular groove 514, and the two ends of the other torsion spring 704 are respectively overlapped with the rotating rod 501 and the circular groove 514, so that when the device is initially used, the handle 510 can be driven 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 pull rope 512 can be rewound by the other torsion spring 704 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 and synchronously fixed, which is beneficial to improve the stability of the device when in use, and further ensure the stability of the injured person during sleep recovery and transfer treatment.

[0049] Working principle: First, when using the device, the foot brake is fixed through the four universal wheels 702 at the bottom of the storage box 1, and then the hinged box board 2 is opened, and then the handle 510 is pulled outward. Under the restriction of the pillar 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, at this time, under the support of the pillar 3, the portable telescopic mechanism 5 is in a horizontal state as a whole, and the handle 510 is continued 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 firstly 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 not 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 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;

[0051] After the automatic splicing is completed, one hand keeps pulling the handle 510, and the other hand rotates the two rotary 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, thereby achieving 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 from being separated from the outer shell 502. At the same time, the vertical slide bar 605 will rotate to a horizontal state, and 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 groove 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 groove 511, and the connecting rod 703 is driven to rotate through the torsion spring 704, so that the two support rods 701 are synchronously rotated from a horizontal angle to a vertical angle, so as to utilize the universal wheel 702 to further support the bed.

[0054] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
