[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 As shown, a fire-fighting material air transport and escape pod includes a pod 1, and a lifting ring 2 is fixed at each of the four corners of the upper end of the pod 1 to facilitate rope connection so as to realize the lifting of the pod 1;

[0029] In this embodiment, a screw is provided at the lower end of the lifting ring 2, and a threaded hole is respectively opened at the four corners of the upper end of the cabin body 1. The screw and the threaded hole are threadedly matched to realize a detachable fixed connection between the lifting ring 2 and the cabin body 1; of course, in some embodiments, the lifting ring 2 and the cabin body 1 can also be fixed by welding.

[0030] like Figure 2 and Figure 3 As shown, one side of the cabin 1 is open, and two door panels 3 are provided on the open side to achieve the blocking and opening of the open side of the cabin 1, so as to facilitate the entry and exit of materials or people into and out of the cabin 1;

[0031] In this embodiment, two connecting seats 11 are provided on the open side of the cabin body 1, and the two door panels 3 are hinged to the two connecting seats 11 respectively, and handles are provided on the inner and outer side surfaces of the door panels 3 to facilitate the operator to close the door panels from inside and outside the cabin respectively.

[0032] A latch assembly 4 is provided at the upper end of the cabin body 1 to fix the door panel 3 in a closed state, and to facilitate fixing the door panel 3 from inside and outside the cabin;

[0033] like Figure 5 and Figure 6 As shown, the latch assembly 4 includes two connecting plates 41, which are distributed up and down and are respectively fixed to the upper ends of the two door panels 3. A through hole is respectively opened on the two connecting plates 41, and when the two door panels 3 close the open side of the cabin body 1, the through holes on the two connecting plates 41 are coaxial; a fixing rod 422 is provided at the upper end of the cabin body 1, and a bottom plate 422 fixed to the cabin body 1 is provided at the lower end of the fixing rod 422, and a top plate 421 is also fixed to the upper end of the fixing rod 422, and a lifting plate 43 is provided between the bottom plate 422 and the top plate 421, and the fixing rod 422 penetrates the lifting plate 43 along the vertical direction. The lowering plate 43 is slidably connected with the lifting plate 43 in the vertical direction. A spring 44 is sleeved on the fixing rod 422. The two ends of the spring 44 are in contact with the top plate 421 and the lifting plate 43 respectively. Under the elastic force of the spring 44, the lifting plate 43 can be tightly attached to the bottom plate 422. A latch 45 and a top rod 46 are fixed to the lower end of the bottom plate 422. When the lifting plate 43 is tightly attached to the bottom plate 422, the latch 45 can simultaneously penetrate the through holes on the two connecting plates 41 to fix the door panel 3 in the closed state. Moreover, at this time, the top rod 46 penetrates the upper end of the cabin body 1 and extends into the interior of the cabin body 1.

[0034] When it is necessary to open the door from the outside first, it is only necessary to manually lift the lifting plate 43 so that the latch 45 leaves the two through holes, and the door panel 3 can be manually opened; when it is necessary to close the door from the inside of the cabin 1, it is only necessary to manually lift the push rod 46 again, and then pull the handles inside the two door panels 3 to close the door panels 3, and then remove the lifting force on the push rod 6, so that the door panels 3 can be closed and locked from the inside of the cabin 1, which is convenient for escape.

[0035] A pressure plate assembly 5 is provided on both sides of the cabin 1, so that the materials in the cabin 1 are pressed and fixed during the transportation of materials, to prevent the materials in the cabin 1 from shaking and colliding with each other during the lifting process, thereby causing damage;

[0036] like Figure 4As shown, the pressing plate assembly 5 includes a pressing plate 51 slidably connected to the cabin body 1 in the vertical direction, and two fixing plates 12 distributed in the vertical direction are arranged on the side of the cabin body 1. A first screw rod 52 is connected between the two fixing plates 12. The first screw rod 52 penetrates the pressing plate 51 in the vertical direction and is threadedly connected thereto. By rotating the first screw rod 52, the pressing plate 51 can be driven to move up and down, so that the materials can be pressed and fixed inside the cabin body 1; and when hoisting firefighters for escape, the pressing plate 51 can be controlled to rise to the highest point to make room;

[0037] Furthermore, in order to ensure the stability of the pressing force of the pressure plate 51 on the material, the first screw rod 52 needs to have a self-locking property, that is, the thread lead angle of the first screw rod 52 is smaller than the equivalent friction angle.

[0038] Of course, the method of driving the pressure plate 51 to rise and fall includes but is not limited to the first screw rod 52 and other structures in this embodiment. In some embodiments, the pressure plate 51 can also be driven to rise and fall by setting an electric push rod on the cabin body 1.

[0039] A mounting groove 13 is provided on the inner side wall of the cabin 1, and a handrail assembly 6 is provided at the mounting groove 13. The handrail assembly 6 includes a handrail 61 that can be received in the mounting groove 13. Two guide rods 611 are provided on the handrail 61. The guide rod 611 penetrates the side wall of the cabin 1 and is slidably connected thereto. A second screw rod 62 is rotatably connected at the center of the mounting groove 13. The second screw rod 62 penetrates the handrail 61 and is threadedly connected thereto. By rotating the second screw rod 62, the handrail 61 can be moved away from the mounting groove 13, which is convenient for personnel in the cabin to hold on to during lifting. When lifting materials, the handrail 61 can be completely received in the mounting groove 13 by rotating the second screw rod 62, so as to avoid interference between the lifting and lowering movement of the pressure plate 51 and the handrail.

[0040] Furthermore, in order to ensure that the handrail rod 61 remains stable after the position is adjusted, the second screw rod 62 needs to have a self-locking property, and the thread lead angle of the second screw rod 62 is smaller than the equivalent friction angle.

[0041] It is worth mentioning that since the second screw rod 62 is located at the center of the installation groove 13 and also at the middle gap between the two pressing plates 51 , there will be no interference with the second screw rod 62 during the lifting and lowering process of the pressing plates 51 .

[0042] Working principle:

[0043] A lifting ring 2 is provided at each of the four corners on the top of the cabin 1 to facilitate lifting, and two pressure plate assemblies 5 are provided inside the cabin 1, so that during the transportation of materials, the materials inside the cabin 1 are pressed and fixed to prevent the materials inside the cabin 1 from shaking and colliding with each other during the lifting process, causing damage; at the same time, a mounting groove 13 is provided on the inner wall of the cabin 1 to accommodate the handrail 61, and a second screw rod 62 is provided to control the handrail 61 to enter and exit the mounting groove, so that the personnel in the cabin can hold on to the handrail 61 during lifting, and it is also ensured that when lifting materials, the handrail 61 is completely received in the mounting groove 13 to avoid the lifting and lowering movement of the pressure plate 51 from interfering with the handrail. A latch assembly 4 is provided at the upper end of the cabin 1 to facilitate fixing the closed state of the door panel 3 from inside and outside the cabin.
