[0001] The utility model relates to the technical field of square cabins, in particular to an expandable medical cabin. Background Art

[0002] The characteristics of the shelter are that it is sturdy, movable, easy to build and transport. Fixed shelters are too small and easy to transport, but the space they provide is limited; fixed shelters are too large and can provide a large space for use, but are not easy to transport. Expandable shelters can be folded into a smaller volume when transported and expanded into a larger space when used, making up for the shortcomings of fixed shelters.

[0003] Expandable shelters often use rigid folding expansion plates or flexible air membranes. Compared with rigid expansion plates, flexible air membranes are lightweight, easy to fold and store, and take up less space when stored. Therefore, expandable shelters that combine flexible air membranes with shelter wall panels are increasingly used. In the prior art, the sealing between the air membrane and the shelter wall panels of expandable shelters is poor, and the air tightness is low, making it difficult to meet medical requirements. However, medical shelters for field emergency and surgery not only need to be able to be expanded and folded quickly and provide a large independent space, but also need to meet medical requirements for high air tightness and high cleanliness.

DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] A specific embodiment of the utility model is as follows Figure 1 As shown, an expandable medical cabin is disclosed, including a main frame 1, a cabin wall panel 2, an air membrane 3, a lifting mechanism 4 and a side panel unfolding mechanism 5.

[0037] The main frame 1 is the main load-bearing structure of the cabin. Figure 2 As shown, the main frame 1 includes an upper frame 12 and a lower frame 11. Columns are provided at the four corners of the upper frame 12 and the lower frame 11. Further, in order to save space and realize the requirement that the upper frame 12 can be lifted, the four corner columns of the main frame 1 are provided in the form of inner and outer sleeves, and the inner sleeve can extend from the outer sleeve, the upper frame column 121 is the inner sleeve, and the lower frame column 111 is the outer sleeve.

[0038] In order to facilitate the transportation of the medical cabin, two forklift holes 13 are respectively provided on both sides of the bottom of the main frame 1 for transferring the cabin by a forklift.

[0039] like Figure 3 As shown, the jacking of the top of the shelter is achieved by a jacking mechanism 4. There are two jacking mechanisms 4, which are arranged at the front and rear end surfaces between the upper frame 12 and the lower frame 11.

[0040] The lifting mechanism 4 includes a slide groove 41 , a sliding block 42 , an inclined rod 43 and a hydraulic cylinder 44 .

[0041] The slide groove 41 is arranged on the top square steel of the end surface of the lower frame 11 and the top square steel of the end surface of the upper frame 12, including a first slide groove 411, a second slide groove 412, a third slide groove 413 and a fourth slide groove 414. The first slide groove 411 and the second slide groove 412 are arranged at the upper ends of the top square steel of the lower frame 11, and the third slide groove 413 and the fourth slide groove 414 are arranged at the lower ends of the top square steel of the upper frame 12. The first to fourth slide grooves are respectively provided with the first to fourth sliding blocks, and the sliding block 42 can slide in the slide groove 41.

[0042] Further, two inclined rods 43 are arranged crosswise between the first slider 421, the second slider 422, the third slider 423 and the fourth slider 424, namely the first inclined rod 431 and the second inclined rod 432. The two ends of the first inclined rod 431 are respectively hinged to the first slider 421 and the fourth slider 424, and the two ends of the second inclined rod 432 are respectively hinged to the second slider 422 and the third slider 423. The length of the first inclined rod 431 is the same as that of the second inclined rod 432, and there is an inclined rod hinge axis at the intersection, and the first inclined rod 431 and the second inclined rod 432 can rotate around the inclined rod hinge axis.

[0043] Further, a hydraulic cylinder 44 is provided at the diagonal rod hinge shaft, and as an alternative to the present embodiment, other driving mechanisms may also be used. The hydraulic cylinder 44 is a telescopic rod hydraulic cylinder 44, and the top of the hydraulic cylinder 44 is fixedly connected to the diagonal rod hinge shaft. When the top of the hydraulic cylinder 44 is pushed upward, the diagonal rod hinge shaft rises, and the first diagonal rod 431 and the second diagonal rod 432 rotate in the direction away from the diagonal rod hinge shaft, and the angle with the horizontal direction increases. Since the third slider 423 and the fourth slider 424 are connected to the square steel 122 at the top of the upper frame, as the third slider 423 and the fourth slider 424 rise, the top of the upper frame 11 is lifted. When the top of the hydraulic cylinder 44 moves downward, the diagonal rod hinge shaft moves downward accordingly, and the first diagonal rod 431 and the second diagonal rod 432 rotate in the direction of the diagonal rod hinge shaft, and the angle with the horizontal direction decreases, and the top of the upper frame 12 drops.

[0044] Under the joint action of the front and rear two lifting mechanisms 4, the front and rear ends of the top of the upper frame 12 rise or fall simultaneously, so as to realize the lifting or lowering of the top of the shelter.

[0045] Compared with the prior art, this embodiment adopts a cross-slanting rod method to achieve the jacking of the top of the shelter, which has a simple structure and a stable jacking.

[0046] like Figure 4 As shown, the square bulkhead panel includes a bottom plate 21, a front plate 22, a rear plate 23, a side plate 24 and a top plate 25. The square bulkhead panel 2 is fixed to the main frame 1 profile by rivets, and a structural adhesive is used to seal the fixed joint surface to ensure the sealing between the square bulkhead panel 2 and the main frame 1.

[0047] The bottom plate 21 is fixed on the bottom frame of the main frame 1, and the front plate 22 and the rear plate 23 are fixed on the front and rear end surfaces of the main frame 1. The front plate 22 is provided with a hydraulic system maintenance door 221, an air conditioning unit 222, a heater maintenance door 223 and a power wall box 224. The rear plate 23 is provided with a cabin entrance door 231, an air circuit wall box and a signal wall box. The door body of the cabin entrance door 231 adopts an aluminum profile structure. In order to ensure the sealing between the door body and the front plate 22, waterproof and sealing strips are installed on the door body. There is a front plate frame 225 on the inner side of the front plate 22, and a rear plate frame on the inner side of the rear plate 23, which are used to fix the air film 3.

[0048] The side panels 24 are located on both sides of the bottom panel 21 . The bottom of the side panels 24 is hingedly connected to the edge of the bottom panel 21 . The side panels 24 can be rotated and opened around the hinge axis.

[0049] In order to achieve a sealing effect, the hinge surface is further provided with a sealing PVC soft cloth to seal the gap between the hinge and the side plate 24 and the bottom plate 21.

[0050] Furthermore, in order to realize the unfolding of the side panels 24 to become the bottom panel 21 of the expansion cabin to expand the cabin space, a side panel unfolding mechanism 5 is provided. The side panel unfolding mechanism 5 has four, including a side panel hinge seat 51, a telescopic rod 52 and a telescopic rod fixing assembly 53.

[0051] The side panel hinge seat 51 is disposed on the outer side of the side panel 24 near the front panel 22 and the rear panel 23 .

[0052] For ease of use and storage, the telescopic rod 52 is a telescopic structure. The telescopic rod 52 is provided with a first end 521 and a second end 522. The diameter of the second end 522 is smaller than the diameter of the first end 521, and the second end 522 can be retracted / extended into the first end 521. The bottom of the second end 522 is connected to the first end 521, and a hook 523 is provided on the top. Furthermore, a roller assembly 524 is connected to the end of the first end 521. It should be noted that the roller assembly 524 includes a roller and a brake component so that the side panel 24 can stop at any position when it is unfolded.

[0053] When the side panel 24 rotates outward, the hook 523 of the telescopic rod 52 is pressed into the hinge shaft of the side panel hinge seat 51 and fixed, and the roller of the telescopic rod 52 contacts the ground and rolls on the ground. As the rotation angle of the side panel 24 increases, the length and tilt angle of the telescopic rod 52 are adjusted. When the side panel 24 is about to fall to the ground, the hook 523 is removed from the side panel hinge seat 51 to lay the side panel 24 flat.

[0054] Furthermore, when the telescopic rod 52 is not in use, the second end 522 is retracted into the first end 521 and fixed to the telescopic rod fixing assembly 53 of the lower frame column 111. The bottom of the telescopic rod fixing assembly 53 has an arc-shaped groove. After the telescopic rod 52 is inserted, it is buckled with a fixing buckle having the same arc-shaped groove, and the telescopic rod 52 is fixed.

[0055] Furthermore, a plurality of auxiliary supports 242 are provided on the outer side of the side panel 24 for serving as ground supports when the side panel 24 is unfolded into a bottom panel, so as to form a flat support surface together with the bottom panel 21 .

[0056] A side panel door lock 241 is provided on the outer side of the side panel 24. When the shelter is folded, the side panel door lock 241 is closed, and before the shelter is unfolded, the side panel door lock 241 is opened.

[0057] The top plate 25 is fixed to the top of the upper frame 12. When the ejection structure lifts the top of the upper frame 12, the top plate 25 is lifted accordingly. Figure 5 As shown, a frame structure composed of top plate square steel 251 is arranged at the lower part of the top plate 25 for fixing the air membrane 3.

[0058] The air film 3 is made of TPU brushed film material and is a welded whole. The top of the air film 3 has an opening for fixing with the top plate frame; the bottom of the air film 3 is fixed to the main frame 1 at the front plate 22 and the rear plate 23 of the cabin, as well as the edges of the bottom plate 21 and the side plate 24.

[0059] When the top of the air membrane 3 is connected to the top plate frame, this embodiment adopts a method of multiple fixing and sealing of the air membrane 3 on the top plate square steel 251. Figure 6As shown, the edge of the air membrane 3 is fixed on the top plate square steel 251, thereby fixed to the entire top frame. Specifically, the top plate square steel 251 includes a first adhesive surface, a second adhesive surface and a third adhesive surface, and the second adhesive surface is located between the first adhesive surface and the third adhesive surface; first, the upper layer and the lower layer of the air membrane are peeled off from the main body of the air membrane 3 at the edge of the air membrane 3, and a part of the peeled upper layer is cut off, so that the length of the lower layer at the edge of the air membrane 3 is greater than the upper layer and the middle layer. The upper layer peeled off from the edge of the air membrane 3 is completely bonded to the first adhesive surface of the top plate square steel 251. It should be noted that in order to make the connection not easy to detach, the bonding height of the upper layer of the air membrane 3 is to the middle and upper part of the first adhesive surface of the top plate square steel 251, that is, after bonding, the height of the upper layer of the air membrane 3 is located at the middle and upper part of the first adhesive surface of the top plate square steel 251. Furthermore, the lower layer of the air membrane peeled off from the edge of the air membrane 3 is completely adhered to the second and third bonding surfaces of the top plate square steel 251, and the end bonding height of the lower layer of the air membrane is to the middle and upper part of the third bonding surface of the top plate square steel 251, which is the same as the bonding height of the upper layer of the air membrane to the first bonding surface.

[0060] In order to strengthen the fixation between the air membrane 3 and the top plate square steel 251 to prevent the air membrane 3 from being separated from the surface of the top plate square steel 251, in addition to bonding, the air membrane 3 and the top plate square steel 251 are fixed with multiple bolts on the side where the lower layer of the air membrane is bonded to the top plate square steel 251. Furthermore, the bolts are glued around with silicone to prevent the addition of bolts from damaging the sealing between the air membrane 3 and the top plate square steel 251.

[0061] Compared with the prior art, in the fixation and sealing of the air membrane 3 flexible body and the top plate square steel 251, the upper and lower layers of the air membrane are separated, and the upper layer is bonded to the first bonding surface of the top plate square steel 251, which is the first level of fixation and sealing; the lower layer is bonded to the second and third bonding surfaces of the top plate square steel 251, which is the second level of fixation and sealing; the air membrane 3 is fixed to the third bonding surface of the top plate square steel 251 with bolts, and the bolts are sealed around with silicone, which is the third level of fixation and sealing. After multiple layers of fixation and sealing, the air membrane 3 and the top plate square steel 251 are tightly fitted, ensuring high air tightness between the air membrane 3 and the cabin body.

[0062] The connection between the bottom of the air film 3 and the cabin wall plate is sealed by a special sealing aluminum profile, and the profile crimping is sealed with a silicone plate.

[0063] When the shelter is folded, the air film 3 is stored inside the shelter wall. When the shelter is expanded, the lifting mechanism 4 lifts the top of the upper frame column 121, and the air film 3 is unfolded upward; after the top plate 25 rises to the right position, the side plate 24 rotates and expands outward, and the bottom of the air film 3 is unfolded outward. At this time, the air film 3 is in a collapsed state.

[0064] There are inflation holes inside the air film 3. When air is inflated into the air film 3, the air film 3 stands up and serves as the three side walls of the expansion cabin. The part connected to the top frame serves as the top plate of the expansion cabin, and the cabin expands the space on the top and two sides at the same time. Since the air film 3 is a whole, there is no need to use a cover cloth on the top, and there is no need to sew the front and back with zippers, etc., which ensures the integrity and sealing of the entire cabin.

[0065] Compared with the prior art, the air membrane 3 in this embodiment is a welded whole from top to bottom, rather than a zipper-stitched structure in the prior art, and the top of the air membrane 3 is directly fixedly connected to the frame of the front plate 22 and the rear plate 23, and no longer uses a shielding cloth separated from the main body of the air membrane 3, thereby ensuring the integrity of the structure of the air membrane 3. At the same time, the top of the air membrane 3 and the top of the top plate frame 251 are sealed with multiple seals, and the bottom of the air membrane 3 and the square cabin wall plate 2 are sealed with a sealed aluminum profile and a silicone plate, thereby ensuring the overall sealing in the expansion cabin.

[0066] The air film 3 is provided with a ring buckle 6 for fixing with the ground nails on the ground, which can prevent wind and enhance the stability of the whole cabin. On the other hand, the cabin can also be hoisted and transferred by the ring buckle 6.

[0067] In order to better adapt to the requirements of the deployment site, the corners of the front plate 22 and the rear plate 23 of the square cabin are equipped with manual leveling mechanisms 7. At the same time, the bottom is also equipped with a support seat and a cushion to adapt to different hardness grounds.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
