Description

Technical Field

[0001] This utility model relates to the field of cable or line installation through walls, floors or ceilings, and more particularly to pipe through hole sealing sleeves and pipe through hole sealing structures. Background Technology

[0002] When arranging the air circuit of a bus, the auxiliary air tank often needs to branch off a portion of its air supply to provide air to the driver's seat or passenger door. In this case, the air pipe needs to pass through the floor or panel inside the vehicle and connect to the door pump connector of the driver's seat or passenger door to achieve air supply. In practical applications, sealing sleeves are often installed at the pipe passages in the floor or panel. These sealing sleeves serve two purposes: protecting the pipes and providing a waterproof and dustproof seal. Existing sealing sleeves are often simply fitted over the pipes and sealed at the pipe passages. While this provides some protection, the waterproof seal is poor, often requiring caulking after installation. This process is problematic because caulking can easily overflow to other areas, affecting the overall appearance, and the application is cumbersome. Furthermore, improper application can result in an unreliable seal.

[0003] Chinese invention patent application CN119944540A discloses a sealing threading structure, which includes a rigid sealing plate and a flexible sealing ring. The pipeline passes through the sealing plate and the sealing ring. The sealing plate is connected to the edge of the pipeline through-hole by screws and presses the sealing ring tightly against the pipeline through-hole. This compression ensures a seal between the sealing ring and the pipeline through-hole. Simultaneously, through a conical surface fit, the sealing ring retracts and grips the pipeline during the pressing process of the sealing plate, ensuring a seal between the sealing ring and the pipeline. While this sealing threading structure achieves a reliable seal, it has a large number of parts and is often used in confined spaces in vehicles, making operation inconvenient. Furthermore, the sealing ring does not completely isolate the pipeline from the wall of the pipeline through-hole, resulting in poor protection for the pipeline. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline through-hole sealing sleeve to solve the problem of numerous components and inconvenient installation and operation in existing pipeline through-hole sealing parts. Simultaneously, this invention also aims to provide a pipeline through-hole sealing structure to solve the same problem.

[0005] The pipeline through-hole sealing sleeve of this utility model includes an integrally injection-molded rubber sleeve body. The middle part of the rubber sleeve body has a pipeline through-hole for the pipeline to pass through and to be tightly sealed with the pipeline. The rubber sleeve body includes a pipeline sheath extending in the same direction as the pipeline, and a sealing connecting plate extending perpendicular to the axis of the pipeline sheath at one end of the pipeline sheath. The sealing connecting plate has screw holes for screw connection to the surface of the plate where the pipeline through-hole is located. The sealing connecting plate has a reinforcing skeleton inside. The screw holes are located on the sealing connecting plate at positions corresponding to the reinforcing skeleton and pass through the reinforcing skeleton. The sealing connecting plate has a sealing ring on the inner side of each screw hole, which surrounds the pipeline through-hole and seals with the edge or opening of the pipeline through-hole.

[0006] Furthermore, the root of the pipeline sheath connected to the sealing connection plate has a sealing ring protrusion surrounding the pipeline sheath. The sealing ring protrusion is used to press and seal against the edge of the pipeline through hole, and the sealing ring protrusion constitutes a sealing ring portion.

[0007] Furthermore, the outer surface of the sealing ring is curved, creating a rounded transition structure between the pipeline sheath and the sealing connection plate.

[0008] Furthermore, pipeline perforation includes a clamping section that interferes with the pipeline and a flared tapered section connecting the small-diameter section to the clamping section.

[0009] Furthermore, the clamping section is located inside the sealing connection plate, and the flared conical hole section is located inside the pipeline sheath.

[0010] Furthermore, the framework is strengthened by tightly connecting the sections.

[0011] Furthermore, the through holes on the reinforced frame corresponding to the clamping section are made to have the same inner diameter as the clamping section so that they can be interference-fitted with the outer surface of the pipeline.

[0012] Furthermore, the inner diameter of the through hole corresponding to the screw hole on the reinforced frame is larger than the inner diameter of the screw hole.

[0013] Furthermore, the screw holes are evenly distributed around the pipe holes.

[0014] Furthermore, the reinforcing frame is made of metal sheets.

[0015] This invention provides a novel pipeline through-hole sealing sleeve. The sealing connecting plate has a reinforced skeleton molded inside, and the screw holes are located on the sealing connecting plate corresponding to and passing through the reinforced skeleton. When the sealing connecting plate is connected to the plate containing the pipeline through-hole using connecting screws, it can be pressed tightly against the plate surface. The sealing ring on the sealing connecting plate can ensure a reliable sealing fit with the edge or opening of the pipeline through-hole. Simultaneously, the pipeline through-hole tightly holds the sealed pipeline, achieving a reliable sealing fit between the rubber sleeve body and the pipeline. Therefore, in use, simply pass the pipeline through the rubber sleeve body and install the pipeline through-hole sealing sleeve at the pipeline through-hole location using connecting screws. This relatively simple operation simultaneously achieves pipeline protection and sealing, and allows for convenient and quick installation even in confined spaces.

[0016] The present invention relates to a pipeline through-hole sealing structure, comprising a through-hole plate having a pipeline through-hole, a pipeline through-hole sealing sleeve having a pipeline through-hole installed thereon, the pipeline through-hole sealing sleeve comprising an integrally injection-molded rubber sleeve body having a pipeline through-hole in the middle of the rubber sleeve body for the pipeline to pass through and for sealing the pipeline, the rubber sleeve body comprising a pipeline sheath extending in the same direction as the pipeline, and a sealing connecting plate extending perpendicular to the axis of the pipeline sheath at one end of the pipeline sheath, the sealing connecting plate having screw holes for screw connection to the surface of the plate where the pipeline through-hole is located, the sealing connecting plate having a reinforcing skeleton inside, the screw holes being located on the sealing connecting plate corresponding to the reinforcing skeleton and passing through the reinforcing skeleton, and the sealing connecting plate having a sealing ring portion on the inner side of each screw hole surrounding the pipeline through-hole and sealingly engaging with the edge or opening of the pipeline through-hole.

[0017] Furthermore, the root of the pipeline sheath connected to the sealing connection plate has a sealing ring protrusion surrounding the pipeline sheath. The sealing ring protrusion is used to press and seal against the edge of the pipeline through hole, and the sealing ring protrusion constitutes a sealing ring portion.

[0018] Furthermore, the outer surface of the sealing ring is curved, creating a rounded transition structure between the pipeline sheath and the sealing connection plate.

[0019] Furthermore, pipeline perforation includes a clamping section that interferes with the pipeline and a flared tapered section connecting the small-diameter section to the clamping section.

[0020] Furthermore, the clamping section is located inside the sealing connection plate, and the flared conical hole section is located inside the pipeline sheath.

[0021] Furthermore, the framework is strengthened by tightly connecting the sections.

[0022] Furthermore, the through holes on the reinforced frame corresponding to the clamping section are made to have the same inner diameter as the clamping section so that they can be interference-fitted with the outer surface of the pipeline.

[0023] Furthermore, the inner diameter of the through hole corresponding to the screw hole on the reinforced frame is larger than the inner diameter of the screw hole.

[0024] Furthermore, the screw holes are evenly distributed around the pipe holes.

[0025] Furthermore, the reinforcing frame is made of metal sheets.

[0026] Furthermore, the length of the pipeline sheath of the pipeline through-hole sealing sleeve is not less than the length of the pipeline through-hole, thus completely isolating the pipeline through-hole.

[0027] This invention improves upon existing pipeline through-hole sealing structures, particularly optimizing the structure of the pipeline through-hole sealing sleeve. A reinforcing skeleton is injection-molded into the sealing connecting plate of the pipeline through-hole sealing sleeve, and screw holes are located on the sealing connecting plate corresponding to and passing through the reinforcing skeleton. This ensures that when the sealing connecting plate is connected to the plate containing the pipeline through-hole using connecting screws, it presses tightly against the plate surface. The sealing ring on the sealing connecting plate guarantees a reliable seal with the edge or opening of the pipeline through-hole. Simultaneously, the pipeline through-hole tightly holds the sealed pipeline, achieving a reliable seal between the rubber sleeve body and the pipeline. Therefore, in use, simply pass the pipeline through the rubber sleeve body and install the pipeline through-hole sealing sleeve at the pipeline through-hole location using connecting screws. This simple operation simultaneously protects and seals the pipeline, allowing for convenient and quick installation even in confined spaces. Attached Figure Description

[0030] This invention addresses the problem that existing sealing threading structures rely on independent sealing plates and sealing rings to seal the pipeline through-holes, resulting in a large number of parts and inconvenient operation and installation. By combining a flexible and elastic sealing sleeve with a rigid reinforcing frame, the compression sealing method is changed. An integral pipeline through-hole sealing sleeve achieves pipeline sealing and protection at the through-hole, with fewer parts and convenient installation and operation.

[0031] The following describes different embodiments of the pipeline through-hole sealing structure of this utility model.

[0032] The pipeline through-hole sealing structure of this utility model can be applied to many occasions, and can be used in locations where pipes and cables pass through panels and require protection and sealing. In this embodiment, the application scenario described in the background art, where air pipes supplying air to passenger doors or driver's seats need to pass through the vehicle floor, will be used as an example.

[0033] The pipeline through-hole sealing structure includes a through-plate body with a pipeline through-hole, and a pipeline through-hole sealing sleeve installed at the location of the pipeline through-hole. For example... Figure 3 As shown, the wiring board in this embodiment is actually the vehicle floor 40. The vehicle floor 40 includes the floor 40 and the floor covering 41 laid on the upper side of the floor 40. The vehicle floor is provided with a pipeline through-hole through which the air supply pipe 5 passes. Since the vehicle experiences continuous and prolonged vibration during operation, as well as harsh operating environments, a pipeline through-hole sealing structure is provided at the pipeline through-hole location to prevent dust and water from entering the vehicle and to prevent the pipeline through-hole from scratching and wearing the pipeline. This seals the pipeline through-hole and protects the passing pipeline.

[0034] The structure of the pipeline through-hole sealing jacket is as follows Figure 1-2 As shown, the pipeline through-hole sealing strip includes an integrally injection-molded rubber sleeve body. The rubber sleeve body has a pipeline through-hole in its center for the pipeline to pass through. To ensure a seal between the rubber sleeve body and the passing pipeline, the pipeline through-hole is fully or at least partially press-fitted into the pipeline along its entire length to achieve a tight seal. Structurally, the rubber sleeve body includes a pipeline sheath 1 extending in the same direction as the pipeline, and a sealing connecting plate 2 extending perpendicular to the axis of the pipeline sheath 1 at one end. The pipeline through-hole is entirely located within the pipeline sheath 1, which surrounds the pipeline, providing protection for the pipeline.

[0035] The sealing connection plate 2 has screw holes 20 for screwing the rubber sleeve body to the surface of the plate where the pipeline through-hole is located. The pipeline sheath 1 is used to extend into the pipeline through-hole to separate the edge or wall of the through-hole from the pipeline. Figure 3As can be seen, when the length of the conduit sleeve 1 is equal to or greater than the length of the conduit through hole on the wiring board, the conduit sleeve 1 can completely isolate the conduit from the conduit through hole, thereby achieving a good protective effect. Of course, in other embodiments, the length of the conduit sleeve 1 can also be less than the length of the conduit through hole on the wiring board.

[0036] The sealing connection plate 2 has a reinforcing skeleton 3 injection-molded inside. The reinforcing skeleton 3 is a rigid skeleton. The screw holes 20 are located on the sealing connection plate 2 corresponding to the reinforcing skeleton 3 and pass through the reinforcing skeleton 3. In this way, when the sealing connection plate 2 is fastened to the vehicle floor 40 by connecting screws, the rigid skeleton can cooperate with the connecting screws to withstand the pressure from the screw heads, thereby ensuring that the sealing connection plate 2 can be reliably pressed against the surface of the vehicle floor 40. Moreover, the sealing connection plate 2 has a sealing ring on the inner side of each screw hole 20, which surrounds the pipeline through hole and seals with the edge or opening of the pipeline through hole. In this way, when the sealing connection plate 2 is pressed against the vehicle floor 40 by connecting screws, the sealing ring can ensure the seal between the sealing connection plate 2 and the vehicle floor 40. Combined with the above-described clamping seal between the pipeline through hole and the pipeline, a reliable seal is ensured at the pipeline through hole location.

[0037] The sealing ring can be one or more convex ring structures located on the surface of the sealing connecting plate 2 facing the pipeline sheath 1. When the sealing connecting plate 2 is pressed tightly onto the vehicle floor 40, the convex ring structure elastically presses against the edge of the pipeline through hole. Due to the elasticity of the rubber material, the convex ring structure acts as a sealing ring, providing a sealing effect between the two pressing surfaces. Figure 2 In the illustrated embodiment, the sealing ring portion is a sealing ring protrusion 12 surrounding the pipeline sheath 1 at the root of the pipeline sheath 1 where it connects to the sealing connecting plate 2. The sealing ring protrusion 12 is used to press and seal against the annular edge at the pipeline through-hole opening. Placing the sealing ring portion at the corner results in greater compression deformation and a better sealing effect. In this embodiment, the outer surface of the sealing ring protrusion 12 is curved, creating a rounded transition structure between the pipeline sheath 1 and the sealing connecting plate 2. In fact, in this embodiment, the sealing ring protrusion 12 is equivalent to a rounded structure at the connection position between the sealing connecting plate 2 and the pipeline sheath 1. This means that the magnitude of the pressing force between the sealing connecting plate 2 and the vehicle floor 40 has less impact on the sealing fit between the sealing ring protrusion 12 and the annular edge. Of course, in other embodiments, the outer surface of the sealing ring protrusion 12 can also be a bevel, i.e., the sealing ring protrusion 12 is equivalent to a chamfered structure at the connection position between the sealing connecting plate 2 and the pipeline sheath 1.

[0038] like Figure 2-3As shown, the reinforcing frame 3 is sheet-like, and its overall shape is consistent with that of the sealing connection plate 2. This ensures the best possible fit between the sealing connection plate 2 and the vehicle floor 40. The reinforcing frame 3 can be made of hard plastic or metal sheet (thin steel plate), and pipelines can be perforated through the reinforcing frame 3.

[0039] To facilitate the passage of pipelines through the pipeline perforation, the pipeline perforation includes a clamping section 10 that is interference-fitted with the pipeline and a flared conical section 11 connecting the clamping section 10 to a small-diameter section. Preferably, the clamping section 10 is located within the sealing connecting plate 2, and the flared conical section 11 is located within the pipeline sheath 1. Since the sealing connecting plate 2 has a reinforcing skeleton 3, and the pipeline perforation passes through the reinforcing skeleton 3, placing the clamping section 10 within the sealing connecting plate 2 ensures a relatively reliable clamping. Furthermore, in one embodiment, the pipeline through hole 31 on the reinforcing skeleton 3, corresponding to the clamping section 10, has the same inner diameter as the clamping section 10. This allows the rubber body of the sealing connecting plate 2 to elastically clamp the pipeline, and also enables a tight seal through the interference fit between the pipeline through hole 31 on the reinforcing skeleton 3 and the outer surface of the pipeline. Of course, in other embodiments, to avoid direct contact between the rigid skeleton and the pipeline, the diameter of the pipeline through hole 31 can be larger than the inner diameter of the clamping section 10.

[0040] The inner diameter of the screw through hole 30 corresponding to the screw through hole 20 on the reinforcing frame 3 can be equal to the inner diameter of the screw through hole 20. In the embodiment shown in the figure, the inner diameter of the screw through hole 30 corresponding to the screw through hole 20 on the reinforcing frame 3 is larger than the inner diameter of the screw through hole 20. When connecting the sealing connecting plate 2 to the vehicle floor 40 by connecting screws, the outer diameter of the connecting screw can be slightly larger than the inner diameter of the screw through hole 20, but smaller than the inner diameter of the screw through hole. In this way, the connecting screw can be waterproofed and corrosion-proofed by the rubber body on the sealing connecting section through the radial contact between the connecting screw and the rubber body.

[0041] In the embodiment shown in the figure, the pipeline through-hole sealing sleeve has one pipeline through-hole and two screw holes 20, which are symmetrically arranged about the pipeline through-hole. The entire sealing connection plate 2 has a prismatic shape with rounded corners at each corner. In other embodiments, the pipeline through-hole is not limited to one; for example, there can be two. The sealing connection plate 2 is generally oval, with the two pipeline through-holes arranged side by side, and two screw holes 20 arranged in a row with the pipeline through-hole, one on the left and one on the right. Alternatively, in other embodiments, the sealing connection plate 2 can also be other shapes, such as a circle, with multiple screw holes 20 arranged around one pipeline through-hole; or a regular polygon, with the pipeline passing through the central area of ​​the regular polygon, and screw holes 20 arranged at each of the apex corners of the regular polygon.

[0042] In the above embodiments, the reinforcing skeleton 3 is entirely inside the sealing connection plate 2, that is, it is completely wrapped by the rubber part of the sealing connection plate 2. In other embodiments, the reinforcing skeleton 3 may also be exposed on the surface facing away from the pipeline sheath 1.

[0043] The embodiment of the pipeline through-hole sealing sleeve of this utility model has the same structure as the pipeline through-hole sealing sleeve structure in the embodiment of the pipeline through-hole sealing structure described above, and will not be described again.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
