Description

Technical Field

[0001] This disclosure relates to the field of sealing technology, and in particular to a trans-cabin sealing structure. Background Technology

[0002] When pipes pass through a cabin, a through-hole larger than the pipe's outer diameter is typically created first. The pipe is then passed through this through-hole to exit the cabin. To maintain the cabin's airtightness, sealant is injected into the through-hole after the pipes are installed, ensuring a sealed contact between the pipes and the cabin.

[0003] However, the aforementioned sealing structure is difficult to disassemble when the pipeline needs adjustment or even repair. Moreover, the sealant is at risk of aging and peeling off after a period of time, affecting the sealing effect of the compartment. Utility Model Content

The first sealing plate and the second sealing plate are located on opposite sides of the connecting plate, and the first sealing plate is sandwiched between the connecting plate and the outer surface of the cabin. The first sealing plate has a second through hole in its middle for the pipeline to pass through, and the second through hole communicates with the first through hole. The second sealing plate is connected to the connecting plate, and the second sealing plate has a sealing hole in its middle for the pipeline to pass through, and the wall of the sealing hole is in sealing contact with the pipeline. Both the first sealing plate and the second sealing plate are structural components with plastic deformation.

[0006] In another implementation of this disclosure, one side of the first sealing plate is abutted against the outer surface of the cabin; the connecting plate includes a bonding connecting plate and a side plate, the side of the bonding connecting plate facing the first sealing plate is abutted against the other side of the first sealing plate and connected to the outer surface of the cabin; the side plate is located on one side of the bonding connecting plate and is perpendicularly connected to the bonding connecting plate, the side plate and the bonding connecting plate define a first space for accommodating the first sealing plate.

[0007] In another implementation of this disclosure, the first wire hole extends from one side of the connecting plate to the middle of the connecting plate, and the side plate and the side where the first wire hole is located are respectively located on opposite sides of the bonding connecting plate.

[0008] In another implementation of this disclosure, the second wire hole extends from one side of the first sealing plate to the middle of the first sealing plate;

[0009] The side plate is fitted to the side where the second wire hole is located.

[0010] In another implementation of this disclosure, at least a portion of the hole wall of the second wire hole away from the side where the second wire hole is located is an arc-shaped hole wall that fits into the pipeline.

[0011] In another implementation of this disclosure, the second sealing plate and the connecting plate are connected by adhesive.

[0012] In another implementation of this disclosure, the first sealing plate further has a first connecting hole that passes through the two opposite surfaces of the first sealing plate; the connecting plate further has a second connecting hole arranged corresponding to the first connecting hole; the through-cabin sealing structure further includes a fastener, one end of which is connected to the first connecting hole and the second connecting hole respectively, and the other end of which is used to connect to the cabin body.

[0013] In another implementation of this disclosure, both the first connecting hole and the second connecting hole are strip-shaped holes and are both open holes with an opening at one end. The opening direction of the first connecting hole is different from the opening direction of the second connecting hole.

[0014] In another implementation of this disclosure, the connecting plate includes a first region and a second region connected together, the first wire hole is located in the first region, the first connecting hole is located in the second region, and the second sealing plate covers the first region.

[0015] In another implementation of this disclosure, the first sealing plate is one of a rubber sponge plate, a silicone sponge plate, a polyurethane foam plate, and a polyethylene foam plate; the second sealing plate is one of a rubber sponge plate, a silicone sponge plate, a polyurethane foam plate, and a polyethylene foam plate.

[0016] The beneficial effects of the technical solutions provided in this disclosure are:

[0017] When the through-cabin sealing structure provided in this embodiment seals a pipe passing through the cabin, the structure includes a connecting plate, a first sealing plate, and a second sealing plate, with the first and second sealing plates located on opposite sides of the connecting plate. The first sealing plate is a structural component capable of plastic deformation and is sandwiched between the connecting plate and the outer surface of the cabin. This allows the connecting plate to make sealing contact with the outer surface of the cabin, further improving the sealing performance of the connection between the connecting plate and the cabin. Furthermore, the first sealing plate has a second through-hole for the pipe to pass through, and the connecting plate has a first through-hole for the pipe to pass through, allowing the pipe to exit through both the first and second through-holes.

[0018] Furthermore, since the second sealing plate is a structural component capable of plastic deformation, it has a sealing hole through which the pipeline passes. The wall of the sealing hole makes sealing contact with the pipeline, thus sealing the area around the pipeline and preventing any gaps in the housing seal after the pipeline passes through the housing, the first sealing plate, and the connecting plate, thereby improving the pipeline's sealing performance. Moreover, because the connecting plate is detachably connected to the outer surface of the housing, this through-housing sealing structure can be repeatedly disassembled and reassembled, facilitating assembly.

[0031] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0032] This disclosure provides a trans-cabin sealing structure, such as Figure 1 As shown, the through-cabin sealing structure includes a connecting plate 1, a first sealing plate 2, and a second sealing plate 3.

[0033] Figure 2 This is a structural diagram of the connecting plate, combined with... Figure 2 The connecting plate 1 has a first through hole 10 in the middle for the pipeline to pass through, and the connecting plate 1 is used to be detachably connected to the outer surface of the cabin.

[0034] Combination Figure 1 The first sealing plate 2 and the second sealing plate 3 are located on opposite sides of the connecting plate 1, and the first sealing plate 2 is sandwiched between the connecting plate 1 and the outer surface of the cabin.

[0035] Figure 3 This is a schematic diagram of the structure of the first sealing plate, combined with... Figure 3 The first sealing plate 2 has a second wire passage hole 20 in the middle for the pipeline to pass through, and the second wire passage hole 20 is connected to the first wire passage hole 10.

[0036] Combination Figure 1 The second sealing plate 3 is connected to the connecting plate 1. The middle part of the second sealing plate 3 has a sealing hole 30 for the pipeline to pass through. The wall of the sealing hole 30 is in sealing contact with the pipeline, and the sealing hole 30 is connected to the second wire passage hole 20. Both the first sealing plate 2 and the second sealing plate 3 are structural components with plastic deformation.

[0037] When the through-cabin sealing structure provided in this embodiment seals a pipe passing through the cabin, the structure includes a connecting plate 1, a first sealing plate 2, and a second sealing plate 3. The first sealing plate 2 and the second sealing plate 3 are located on opposite sides of the connecting plate 1, and the first sealing plate 2 is a plastically deformable structural component. The first sealing plate 2 is sandwiched between the connecting plate 1 and the outer surface of the cabin. This allows the connecting plate 1 to make sealed contact with the outer surface of the cabin, further improving the sealing performance between the connecting plate 1 and the cabin. Furthermore, the first sealing plate 2 has a second through-hole 20 for the pipe to pass through, and the connecting plate 1 has a first through-hole 10 for the pipe to pass through. Thus, the pipe can pass through both the first through-hole 10 and the second through-hole 20.

[0038] Furthermore, since the second sealing plate 3 is a structural component capable of plastic deformation, it has sealing holes 30 for the pipeline to pass through. The wall of the sealing hole 30 is in sealing contact with the pipeline, thus sealing the area around the pipeline through the second sealing plate 3. This prevents the pipeline from failing to seal properly after passing through the cabin, the first sealing plate 2, and the connecting plate 1, thereby improving the pipeline's sealing performance. Moreover, since the connecting plate 1 is detachably connected to the outer surface of the cabin, this through-cabin sealing structure can be repeatedly disassembled and reassembled, facilitating assembly.

[0039] In other words, the through-chamber sealing structure provided in this embodiment can not only be repeatedly disassembled and reassembled, but also seal the pipeline, greatly improving the convenience of the through-chamber sealing structure.

[0040] Optionally, the first sealing plate 2 is one of a rubber sponge plate, a silicone sponge plate, a polyurethane foam plate, or a polyethylene foam plate.

[0041] The second sealing plate 3 is one of the following: rubber sponge board, silicone sponge board, polyurethane foam board, and polyethylene foam board.

[0042] The first sealing plate 2 and the second sealing plate 3 can be of the same or different types.

[0043] By setting the first sealing plate 2 and the second sealing plate 3 as one of the following materials: rubber sponge board, silicone sponge board, polyurethane foam board, and polyethylene foam board, the plastic deformation properties of the materials listed above can be utilized to enable the first sealing plate 2 and the second sealing plate 3 to have good sealing performance.

[0044] In this embodiment, the sealing hole 30 is a circular hole with an interference fit to the pipeline. In this way, after the pipeline passes through the sealing hole 30, it will be well sealed by the second sealing plate 3.

[0045] Optionally, the first sealing plate 2 is a plate with the same shape as the outer surface of the cabin, and one side of the first sealing plate 2 is attached to the outer surface of the cabin.

[0046] In the above implementation, the first sealing plate 2 is set as a plate with the same shape as the outer surface of the cabin, so that the first sealing plate 2 can fit tightly with the outer surface of the cabin, thereby improving the sealing performance.

[0047] Figure 4 for Figure 3 Side view, see continue Figure 4 The first sealing plate 2 includes a first main plate 21 and a first bent plate 22 connected to one side of the first main plate 21. The first bent plate 22 is bent relative to the first main plate 21 toward the connecting plate 1. Both the first main plate 21 and the first bent plate 22 are used to fit against the outer surface of the cabin.

[0048] In other words, the shape of the first sealing plate 2 is entirely determined by the shape of the outer surface of the cabin. In order to make the first sealing plate 2 fit perfectly against the outer surface of the cabin, the shape of the first sealing plate 2 changes with the change of the outer surface of the cabin.

[0049] Figure 5 for Figure 2 The side view, combined with Figure 5 Optionally, the connecting plate 1 includes a bonding connecting plate 11 and a side plate 12. The side of the bonding connecting plate 11 facing the first sealing plate 2 is bonded to the other side of the first sealing plate 2 and connected to the outer surface of the cabin. The first wire hole 10 passes through the opposite sides of the bonding connecting plate 11.

[0050] Figure 6 for Figure 2 The front view, combined with Figure 6 The side plate 12 is located on one side of the bonding plate 11 and is perpendicularly connected to the bonding plate 11. The side plate 12 and the bonding plate 11 define a first space for accommodating the first sealing plate 2.

[0051] In the above implementation, since the bonding plate 11 is bonded together with the first sealing plate 2 and connected to the outer surface of the cabin, when the bonding plate 11 is connected to the outer surface of the cabin, it will squeeze the first sealing plate 2, thereby achieving a sealed connection between the connecting plate 1 and the outer surface of the cabin through the first sealing plate 2.

[0052] The side plate 12 is used to define a first space for accommodating the first sealing plate 2 with the bonding plate 11, so as to limit the first sealing plate 2.

[0053] In this embodiment, the bonding connecting plate 11 includes a second main plate 111 and a second bent plate 112 connected to one side of the second main plate 111. The second bent plate 112 is bent relative to the second main plate 111 toward the connecting plate 1. The second main plate 111 is used to bond with the first main plate 21, and the second bent plate 112 is used to bond with the first bent plate 22.

[0054] In other words, the shape of the bonding plate 11 depends entirely on the shape of the first sealing plate 2. In order for the bonding plate 11 to fit completely with the first sealing plate 2, the shape of the bonding plate 11 changes as the first sealing plate 2 changes.

[0055] Optionally, the first wire hole 10 extends from one side of the connecting plate 1 to the middle of the connecting plate 1, and the side plate 12 and the side where the first wire hole 10 is located are respectively located on opposite sides of the connecting plate 11.

[0056] In the above implementation, the first wire-passing hole 10 is set to extend from one side of the bonding plate 11 to the middle of the bonding plate 11. This allows the first wire-passing hole 10 to pass through one side of the bonding plate 11, thereby facilitating the removal and placement of pipelines from the side of the bonding plate 11.

[0057] See you again Figure 3 Optionally, the second wire passage 20 extends from one side of the first sealing plate 2 to the middle of the first sealing plate 2. The side plate 12 is fitted with the side where the second wire passage 20 is located.

[0058] In the above implementation, the second wire hole 20 is provided with the above structure, which also allows the second wire hole 20 to pass through one side of the first sealing plate 2, thereby facilitating the removal and placement of the pipeline from the side of the first sealing plate 2.

[0059] Furthermore, the side plate 12 fits into the side where the second wire hole 20 is located, which can seal the pipeline in the second wire hole 20 to further limit the pipeline.

[0060] In this embodiment, in order to further improve the installation stability of the connecting plate 1, the side wall of the cabin has a slot for accommodating the side plate 12, and the side plate 12 is located in the slot and is engaged with the side wall of the cabin.

[0061] Optionally, at least a portion of the hole wall of the second wire hole 20 on the side away from the second wire hole 20 is an arc-shaped hole wall 202 that fits against the pipeline.

[0062] In the above implementation, the arc-shaped hole wall 202 is used to fit with the pipeline so as to effectively limit the pipeline.

[0063] In order to further ensure good contact between the pipeline and the arc-shaped hole wall 202 of the second through hole 20, the radius of the arc corresponding to the arc wall 202 is the same as or slightly larger than the outer diameter of the pipeline.

[0064] Optionally, the first sealing plate 2 also has a gap 203, one end of which is connected to the second wire passage hole 20, and one end of the gap 203 extends from the arc-shaped hole wall 202 toward a direction away from the second wire passage hole 20.

[0065] The gap 203 can increase the deformation energy of the first sealing plate 2, so that the pipeline can pass smoothly through the second wire hole 20.

[0066] Figure 7 This is a schematic diagram of the second sealing plate, combined with... Figure 7 The second sealing plate 3 is a square plate. The second sealing plate 3 is connected to the connecting plate 1 by adhesive.

[0067] In the above implementation, the second sealing plate 3 has adhesive on one surface facing the connecting plate 1, so that the second sealing plate 3 and the connecting plate 1 can be connected together by adhesive.

[0068] In this embodiment, the adhesive is a hot melt adhesive (such as EVA or PA) that is applied after heating and then cooled and cured.

[0069] In other examples, the second sealing plate 3 can also be connected to the connecting plate 1 in other ways, such as by fasteners, snap-fits, or insert molding, etc.

[0070] Alternatively, the surface of the first sealing plate 2 away from the connecting plate 1 can also be connected to the cabin by adhesive.

[0071] In the above implementation, the surface of the first sealing plate 2 away from the connecting plate 1 is provided with adhesive, which allows the first sealing plate 2 to be directly pasted onto the outer surface of the cabin, further facilitating the positioning of the first sealing plate 2.

[0072] In other examples, the first sealing plate 2 may not be fitted with adhesive, but may be connected to the outer surface of the cabin only by fasteners or the like.

[0073] See you again Figure 2 and Figure 3 Optionally, the first sealing plate 2 also has a first connecting hole 200 penetrating the two opposite surfaces of the first sealing plate 2. The connecting plate 1 also has a second connecting hole 100 arranged corresponding to the first connecting hole 200.

[0074] The through-cabin sealing structure includes fasteners, one end of which is connected to the first connecting hole 200 and the second connecting hole 100 respectively, and the other end of which is used to connect to the cabin body.

[0075] In the above implementation, the arrangement of the first connecting hole 200 and the second connecting hole 100 facilitates connection with the fastener, enabling the fastener to be detachably connected with the first sealing plate 2 and the connecting plate 1, etc.

[0076] For example, fasteners include screws, nuts, washers, etc.

[0077] For example, both the first connecting hole 200 and the second connecting hole 100 are strip-shaped holes and are open holes with an opening at one end. The opening direction of the second connecting hole 100 is different from the opening direction of the first connecting hole 200.

[0078] The first connecting hole 200 and the second connecting hole 100 are set as open holes, so that when the first sealing plate 2 and the connecting plate 1 are fastened to the cabin body, the position of the fastener in the first connecting hole 200 and the second connecting hole 100 can be adjusted at any time according to the position of different connecting holes in the cabin body. This makes it easier to flexibly adjust the position of the fastener in the first sealing plate 2 and the connecting plate 1 according to the structure of the cabin body, and facilitates the connection.

[0079] Combination Figure 2 Optionally, the connecting plate 1 includes a first region 101 and a second region 102 connected together. A first wire hole 10 is located in the first region 101, a second connecting hole 100 is located in the second region 102, and a second sealing plate 3 covers the first region 101. This allows the second sealing plate 3 to seal the location of the first wire hole 10, thus sealing the area around the pipeline.

[0080] To simplify the division between the first region 101 and the second region 102, in this embodiment, the first region 101 mentioned above is actually the board surface corresponding to the second main board 111 in the bonding connecting plate 11, and the second region 102 is the board surface corresponding to the second bending plate 112.

[0081] In this embodiment, there are two of each of the first wire passage hole 10, the second wire passage hole, and the sealing hole 30. In other examples, the number of the first wire passage hole 10, the second wire passage hole, and the sealing hole 30 may also be other numbers, and the specific number can be set according to the corresponding pipeline.

[0082] The working process of the through-cabin sealing structure provided in this embodiment is briefly described below:

[0083] When sealing a pipe passing through a compartment using the through-compartment sealing structure provided in this embodiment, firstly, the first sealing plate 2 is tightly fitted to the outer surface of the compartment, allowing the pipe to pass through the second through-hole 20 of the first sealing plate 2. Then, the connecting plate 1 and the first sealing plate 2 are respectively fastened to the compartment, so that the first sealing plate 2 is tightly pressed between the connecting plate 1 and the side wall of the compartment, allowing the pipe to pass through the first through-hole 10. Next, the second sealing plate 3 is connected to the side of the connecting plate 1 away from the first sealing plate 2, allowing the pipe to pass through the sealing hole 30 to achieve a seal.

[0084] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
