Description

TECHNICAL FIELD

[0001] The present application relates to the field of multifunctional shelter, in particular to a shelter sealing structure. BACKGROUND

[0002] The field operation vehicle has multiple functions such as communication and support, and the shelter is one of the main components of the field operation vehicle. The shell strength of the shelter meets the bulletproof standard. The door is the main way of electromagnetic leakage of the cabin body, and its performance is crucial to the shielding effectiveness of the shielding body. The cabin side door is mainly composed of a door body, a door frame, a hinge, a locking mechanism and the like. The electrical connection between them and the rest of the cabin body and all the gaps need electromagnetic shielding treatment to achieve effective shielding effectiveness. It should also have air tightness, water tightness, reliable usability and other functions.

[0003] In actual engineering practice, the following problems exist:

[0004] 1. The gap between the large cabin door and the hatch in the prior art is generally sealed by an inflatable seal. Such a cabin door generally has a large circumference, and is affected by the machining and assembly precision or is affected by the change in environmental temperature to produce thermal expansion and contraction deformation, resulting in inconsistent or changing gaps that need to be sealed. The change range is generally 3-5mm or even larger, and it is difficult to achieve ideal sealing effect with ordinary sealing strips. In this case, a sealing product that can change with the gap is needed, and the inflatable seal is a new sealing technology developed to meet this sealing requirement.

[0005] The existing inflatable seal, see CN210003806U, has an inflation pipe arranged on the clamping part. However, the clamping part with the inflation pipe cannot be clamped into the door. The patent does not design how the clamping part is clamped and how the inflation pipe is disassembled and assembled with the sealing ring body. This leads to the problem of interference during installation of the inflation air nozzle in actual work.

[0006] 2. In the field of existing technology, the shelter is different from ordinary doors and door bodies. Because the cabin body and the cabin door have a bulletproof standard, there are many layers of various materials, frames and components, and there is a separate arm to drive the movement between the cabin body and the cabin door. This leads to the need for the precision of multiple components to meet the size alignment. Affected by the machining and assembly precision or affected by the change in environmental temperature to produce thermal expansion and contraction deformation, the thermal expansion and contraction performance of multiple different materials or the machining precision is different, and there is a size interference problem when assembling each component.

[0007] 3. The inflatable seal between the cabin body and the cabin door in the prior art is difficult to maintain when maintenance or inflation is needed because it is clamped in the corner. If it is completely disassembled for maintenance, the time cost is too high.

[0008] Four, the inflatable seal between the cabin body and the cabin door in the prior art, the corresponding maintenance parts lack a separate storage location, and there is no suitable toolbox and suitable space for storing them. SUMMARY

[0014] When the cabin door is opened, the sealing cap is removed, one end of the bending piece is connected to the connecting piece, and the other end of the bending piece is connected to the air nozzle, and the air nozzle is provided with an opening and closing structure inside.

[0015] Preferably, the sealing body comprises a symmetry plane, and the connecting piece is located on one side of the symmetry plane.
