Abstract
Description
Technical Field
[0001] This utility model belongs to the field of amphibious vehicle technology, and more specifically, it relates to a sealing structure for a through-hole in an amphibious vehicle. Background Technology
[0002] Amphibious vehicles often have through-holes in their hulls during pipeline layout and component (part) installation. These through-holes allow pipelines and fasteners to pass through. During assembly, sealing measures must be taken to prevent leakage at these points when the through-holes are submerged below the waterline, affecting sealing performance and the amphibious vehicle's navigation safety. Current sealing methods for the through-holes and their mating points with pipeline joints and bolts involve applying sealant, relying on the sealant's adhesion and aggregation at the gaps to achieve a waterproof seal. However, the gaps between the through-holes and the outer diameters of the pipe joints and bolts are small, making it difficult to fill with sufficient sealant. Similarly, the steps on the pipe joint and bolt ends extending slightly beyond the through-hole diameter also make it difficult to fill with sufficient sealant. To achieve a seal, a certain amount of sealant must also be applied around the circumference of the through-hole extending beyond the steps on the pipe joint and bolt ends, resulting in significant sealant overflow. Sealant is prone to loosening and peeling under vibration and external impact. Direct exposure to light and water will accelerate aging, affecting adhesion and causing it to fall off. All of these will affect the sealing performance of the vehicle body.
[0003] Existing technology includes a device titled "A Buoyancy Assistance Device for Amphibious Armored Vehicles," with publication number CN108928196A. This technology relates to a buoyancy assistance device, specifically a buoyancy assistance device for use on amphibious armored vehicles, primarily addressing the technical problem of lack of self-rescue means when an amphibious armored vehicle encounters water ingress while in water. It comprises an even set of buoyancy assistance components and a centralized control system. Each buoyancy assistance component consists of a float system, a gas generator, an inflation pipeline, a frame, and mounting accessories. The float system is installed within the frame and connected to the gas generator via the inflation pipeline; the frame is fixedly installed on both sides of the vehicle body using mounting accessories. The control system can employ various control methods, including pure pneumatic control, wired electrical control, and wireless remote control. A common feature is that the control system is primarily installed inside the vehicle, allowing for one-button activation without leaving the vehicle to provide buoyancy. It is characterized by convenient operation, rapid deployment, easy maintenance, safety, reliability, and reusability, and can be widely applied to various types of amphibious armored vehicles.
[0004] However, this technology does not address the technical issues and solutions of this application. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an amphibious vehicle through-hole sealing structure that is simple in structure, ensures reliable arrangement of pipelines or parts when pipelines pass through or parts are installed, and effectively seals through-holes through which pipeline joints or bolts pass, in order to address the shortcomings of the existing technology.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] This utility model is a sealing structure for a wall-penetrating hole of an amphibious vehicle. A wall-penetrating hole is provided on the vehicle body, and a limiting end is provided on the through-piece. The through-piece passes through the wall-penetrating hole, and a sealing washer is fitted on one end of the through-piece. The diameter of the sealing washer is larger than the diameter of the wall-penetrating hole, and a nut is screwed on the threaded part of the other end of the through-piece.
[0008] A sealing gasket is fitted onto the through-piece, and the sealing gasket is located between the limiting end of the through-piece and the sealing gasket.
[0009] The diameter of the sealing gasket is greater than or equal to the diameter of the sealing washer.
[0010] The aforementioned through-hole component is a through-plate pipe joint or bolt.
[0011] When the through-piece is a through-plate pipe joint, a pipeline passes through the inside of the through-plate pipe joint.
[0012] When the through-bolt is a bolt, the part to be fixed is fitted onto the bolt, and the part to be fixed is fixed between the vehicle body and the nut.
[0013] The sealing gasket includes a body and a protrusion, which are configured in a T-shape.
[0014] The protruding part of the sealing gasket extends into the through hole of the sealing gasket plate.
[0015] The outer ring of the pipeline is fitted with a ferrule, and the ferrule fitting nut is screwed onto the outer ring of the through-plate pipe fitting.
[0016] A flat washer and a spring washer are provided between the part to be fixed and the nut.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] The amphibious vehicle through-wall hole sealing structure of this utility model features through-wall holes on the vehicle body, penetrating through the vehicle body panels to facilitate the passage of pipelines or the fixing of components. A through-hole component passes through the through-wall hole. When pipelines need to pass through, the through-hole component is a through-plate pipe connector, allowing the pipeline to pass through. The through-plate pipe connector then needs to be fixed, and the through-wall hole needs to be sealed. For fixing, a limiting end is provided on the through-hole component. After passing through the through-wall hole, the limiting end is located at one end of the vehicle body, and a nut is screwed onto the through-hole component at the other end of the vehicle body to fix the through-hole component to the vehicle body. For sealing, a sealing washer is fitted onto the through-hole component. After the through-hole component is fixed with the nut, the sealing washer reliably adheres to the surface of the vehicle body panel, achieving an effective seal. When it is necessary to fix components, the through-hole component is a bolt. The bolt passes through the through-wall hole, with the bolt end serving as a limiting end. The bolt then needs to be fixed, and the through-wall hole needs to be sealed. When fixing, the limiting end of the through-hole is located at one end of the vehicle body after the through-hole is passed through it, and a nut is screwed on the through-hole at the other end of the vehicle body to fix the through-hole to the vehicle body; when sealing, a sealing gasket is fitted on the through-hole, and after the through-hole is fixed by the nut, the sealing gasket reliably fits the surface of the plate of the vehicle body to achieve effective sealing.

[0023] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0024] As attached Figure 1 Appendix Figure 2As shown, this utility model is a sealing structure for a wall-penetrating hole of an amphibious vehicle. A wall-penetrating hole 9 is provided on the vehicle body 1, and a limiting end 11 is provided on the through-piece 10. The through-piece 10 passes through the wall-penetrating hole 9, and a sealing washer 6 is fitted onto one end of the through-piece 10. The diameter of the sealing washer 6 is larger than the diameter of the wall-penetrating hole 9. A nut 2 is screwed onto the threaded part of the other end of the through-piece 10. The above structure addresses the shortcomings of the prior art by proposing an improved technical solution. In the structural design, a wall-penetrating hole 9 is provided on the vehicle body 1, penetrating through the plate of the vehicle body to allow the passage of pipeline 12 or the fixing of parts 15. The through-piece 10 passes through the wall-penetrating hole 9. When pipeline 12 needs to pass through, the through-piece 10 becomes a through-plate pipe joint 5, allowing pipeline 12 to pass through. Then, it is necessary to fix the through-plate pipe joint 5 and seal the wall-penetrating hole 9. When fixing, a limiting end 11 is provided on the through-piece 10. After the through-piece 10 passes through the through-wall hole 9, the limiting end 11 is located at one end of the vehicle body 1. A nut 2 is screwed onto the threaded part of the through-piece 10 at the other end of the vehicle body 1 to fix the through-piece 10 to the vehicle body 1. When sealing, a sealing washer 6 is fitted on the through-piece. After the through-piece 10 is fixed by the nut 2, the sealing washer 6 reliably fits against the surface of the plate of the vehicle body 1 to achieve effective sealing. When it is necessary to fix part 15, the through-piece is a bolt 8. The bolt 8 passes through the through-wall hole 9, and the bolt end is the limiting end 11. Then, it is necessary to fix the bolt 8 and seal the through-wall hole 9. When fixed, the limiting end 11 of the through-hole 10 is located at one end of the vehicle body 1 after passing through the through-hole, and the nut 2 is screwed onto the threaded part of the through-hole 10 at the other end of the vehicle body 1 to fix the through-hole 10 to the vehicle body 1; when sealing, a sealing washer 6 is fitted on the through-hole 10. After the through-hole 10 is fixed by the nut 2, the sealing washer 6 reliably fits against the surface of the plate of the vehicle body 1 to achieve effective sealing. The amphibious vehicle through-hole sealing structure of this utility model has a simple structure. When the vehicle body pipelines pass through or parts are installed, it ensures the reliable arrangement of pipelines or parts, and effectively seals the through-holes through which pipeline joints or bolts pass.
[0025] A sealing gasket 7 is fitted onto the through-piece 10, and the sealing gasket 7 is located between the limiting end 11 of the through-piece 10 and the sealing gasket 6. In this structure, the sealing gasket 7 is used to clamp and fix the sealing gasket 6 from the outside, so that the sealing gasket 6 can be reliably fitted and the sealing effect is improved.
[0026] The diameter of the sealing gasket 7 is greater than or equal to the diameter of the sealing gasket 6. In this structure, with the diameter of the sealing gasket 7 greater than or equal to the diameter of the sealing gasket 6, the sealing gasket is reliably clamped, resulting in a planar structure for the sealing gasket, reliably sealing the through-wall hole, and providing good sealing performance.
[0027] The through-piece 10 is either a through-plate pipe connector 5 or a bolt 8. When the through-piece 1 is a through-plate pipe connector 5, a pipe 12 passes through the inside of the through-plate pipe connector 5. When the through-piece 10 is a bolt 8, a part 15 to be fixed is fitted onto the bolt 8, and the part 15 to be fixed is fixed between the vehicle body 1 and the nut 2. The above structure... Figure 1 This is Embodiment 1 of the present invention, which is aimed at the structure of pipeline arrangement, wherein the through-piece 10 of the structure is a through-plate pipe joint 5. Figure 2 This is Embodiment 2 of the present invention, which addresses the structure of the parts arrangement, in which the through-hole 10 is a bolt 8. Both structures meet practical requirements and reliably seal the through-hole 9.
[0028] The sealing gasket 6 includes a body portion 13 and a protrusion portion 14, which are configured in a T-shape. The protrusion portion 14 of the sealing gasket 6 extends into the through hole of the sealing gasket plate 7. With this structure, the sealing gasket 6 can extend into the interior of the sealing gasket plate 7. After the through-piece 10 is fixed to the vehicle body 1 by the nut 2, both the body portion 13 and the protrusion portion 14 are reliably compressed by the relevant components, effectively improving the sealing effect.
[0029] The outer ring of the pipeline 12 is provided with a retaining sleeve 16, and the outer ring of the through-plate pipe joint 5 is screwed with a retaining sleeve joint nut 17. In the above structure, the retaining sleeve 16 is fixedly provided on the outer ring of the pipeline 12. After the pipeline passes through, the retaining sleeve joint nut 17 is screwed on the outer ring of the through-plate pipe joint 5 to fix the retaining sleeve, thereby restricting pipeline movement.
[0030] A flat washer 3 and a spring washer 4 are provided between the part to be fixed 15 and the nut 2.
[0031] The amphibious vehicle wall-penetrating hole sealing structure of this utility model has a wall-penetrating hole 9 on the vehicle body 1, which passes through the plate of the vehicle body to allow the passage of pipeline 12 or the fixation of part 15. When pipeline 12 needs to pass through, the through-piece 10 is a through-plate pipe joint 5, in which case pipeline 12 can pass through the through-plate pipe joint 5, and then the through-plate pipe joint 5 needs to be fixed and the wall-penetrating hole 9 needs to be sealed. When fixing, a limiting end 11 is provided on the through-piece 10. After the through-piece 10 passes through the wall-penetrating hole 9, the limiting end 11 is located at one end of the vehicle body 1, and a nut 2 is screwed on the threaded part of the through-piece 10 at the other end of the vehicle body 1 to fix the through-piece 10 to the vehicle body 1; when sealing, a sealing washer 6 is fitted on the through-piece. After the through-piece 10 is fixed by the nut 2, the sealing washer 6 reliably fits against the surface of the plate of the vehicle body 1 to achieve effective sealing. When it is necessary to fix part 15, the through part is bolt 8, which passes through the through hole 9. The bolt end is the limiting end 11. Then, it is necessary to fix bolt 8 and seal through hole 9. During fixing, after through part 10 passes through the through hole, the limiting end 11 is located at one end of vehicle body 1. Nut 2 is screwed on the threaded part of through part 10 at the other end of vehicle body 1 to fix through part 10 to vehicle body 1. During sealing, sealing gasket 6 is fitted on through part 10. After through part 10 is fixed by nut 2, sealing gasket 6 reliably fits the plate surface of vehicle body 1 to achieve effective sealing of through hole 9.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
