[0035] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below are examples for explaining the present application and should not be construed as limiting the present application.

[0036] The sealing plug 10 according to the embodiments of the present application is described below with reference to the accompanying drawings.

[0037] With reference to Figures 1-9 The sealing plug 10 according to the first aspect of the present application is used to seal the through hole 31 of the perforated plate member 30, for example, the perforated plate member 30 can be a vehicle body sheet metal. The size of the through hole 31 can be greater than or equal to 40 mm.

[0038] The sealing plug 10 includes an inner ring support 1 and an outer ring rubber 2. The inner ring support 1 is in the shape of a cylinder, the inner ring support 1 is arranged in the through hole 31, and the inner ring support 1 is used to clamp the perforated plate member 30. For example, the inner ring support 1 can be a plastic part, and the inner ring support 1 can also be a metal part. The outer ring rubber 2 is wrapped on the outer surface of the inner ring support 1 to seal the through hole 31. For example, the outer ring rubber 2 can be a rubber part, and the outer ring rubber 2 can also be a silicone part.

[0039] By wrapping the outer ring rubber 2 on the inner ring support 1, the inner ring support 1 can support the outer ring rubber 2, reduce the risk of deformation of the outer ring rubber 2 leading to sealing failure, and improve the reliability of the sealing plug 10.

[0040] By setting the inner ring support 1 to be cylindrical, the weight of the inner ring support 1 can be reduced, the production cost of the inner ring support 1 can be reduced, and at the same time, the inner ring support 1 can have a certain amount of deformation, so that the inner ring support 1 can press the outer ring rubber 2 against the radial inner wall of the through hole 31, further improving the sealing effect of the sealing plug 10.

[0041] By clamping the inner ring support 1 and the perforated plate member 30, it is convenient to assemble the sealing plug 10 into the through hole 31, fix the sealing plug 10 relative to the perforated plate member 30, and improve the convenience of assembling the sealing plug 10.

[0042] For example, when the inner ring support 1 is a plastic piece, the inner ring support 1 can be a polyethylene piece, a polypropylene piece or a polyvinyl chloride piece, so that the inner ring support 1 has good corrosion resistance, and at the same time, the overall mass of the inner ring support 1 is lighter. When the inner ring support 1 is a metal piece, the inner ring support 1 can be an iron piece, a copper piece or an aluminum piece, so that the inner ring support 1 has high structural strength, effectively reduces the risk of stress deformation of the inner ring support 1 causing the sealing plug 10 to fail to seal, and improves the reliability of the sealing plug 10.

[0043] With reference to Figure 4 According to some embodiments of the present application, the inner ring support 1 includes a clamping portion 11 and a sealing portion 12, the clamping portion 11 and the sealing portion 12 are arranged along the axial direction of the inner ring support 1, the clamping portion 11 is provided in the through hole 31, and the clamping portion 11 is used for clamping the hole plate 30, the sealing portion 12 protrudes the clamping portion 11 in the radial direction, and the surface of the sealing portion 12 in the axial direction towards the clamping portion 11 is a boss surface 121. When the sealing portion 12 passes through the through hole 31, the boss surface 121 can abut against the hole plate 30 to fix the sealing plug 10 relative to the hole plate 30 by cooperating with the clamping portion 11. In a specific installation, the sealing portion 12 can be arranged on one side of the water surface of the hole plate 30, so that when the sealing plug 10 is stressed from one side of the water surface, the boss surface 121 can abut against the hole plate 30, reducing the risk of the sealing plug 10 being pushed out of the through hole 31 due to excessive stress (when the hole plate 30 is a vehicle body sheet metal, the stress on the sealing plug 10 can include the following two cases: one, the pressure exerted by water on the sealing plug 10 when the vehicle 100 wades through water; two, the pressure exerted by the sealing plug 10 by mistake), improving the reliability of the sealing plug 10.

[0044] With reference to Figure 3 , Figure 4 , Figure 8 and Figure 9 According to some embodiments of the present application, the outer ring rubber body 2 includes a main body portion 21, a surrounding portion 22 and a water stopping portion 23, the main body portion 21 is located on the side of the sealing portion 12 away from the clamping portion 11 in the axial direction, the surrounding portion 22 is arranged around the outer circumferential side of the main body portion 21, and the surrounding portion 22 is connected to the main body portion 21, the surrounding portion 22 is wrapped around the radial outer surface of the sealing portion 12, and the water stopping portion 23 is connected to one end of the surrounding portion 22 away from the main body portion 21 in the axial direction, and the water stopping portion 23 is connected to the boss surface 121.

[0045] Meanwhile, the main body 21 is arranged on the sealing part 12 at the side axially away from the clamping part 11, and the water stop part 23 is connected to the surrounding part 22 at the end axially away from the main body 21, so that the outer ring rubber 2 covers the two end faces of the sealing part 12 in the axial direction, the sealing part 12 can limit the outer ring rubber 2, the risk of the outer ring rubber 2 falling off the sealing part 12 is reduced, and the reliability of the sealing plug 10 is improved. For example, the inner ring support 1 and the outer ring rubber 2 are integrated, so that the inner ring support 1 and the outer ring rubber 2 can be more reliably connected together, further reducing the risk of the outer ring rubber 2 falling off the sealing part 12, and improving the reliability of the sealing plug 10.

[0046] When the sealing plug 10 is subjected to force from the side of the wading surface, the water stop part 23 is pressed against the boss face 121 and the hole plate, and the water stop part 23 is deformed under pressure, thereby better sealing the through hole 31 and reducing the risk of water flowing from the water stop part 23 to the through hole 31, thereby improving the reliability of the sealing plug 10.

[0047] Referring to Figures 3-6 , Figure 8 and Figure 9 , in some optional embodiments of the utility model, the inner ring support 1 further comprises an elastic stop piece 13, one end of the elastic stop piece 13 is connected to the clamping part 11, the other end of the elastic stop piece 13 extends obliquely towards the boss face 121, and the elastic stop piece 13 is spaced from the boss face 121 in the axial direction of the clamping part 11. When installing the sealing plug 10, the elastic stop piece 13 can be deformed in the radial direction towards the clamping part 11, the elastic stop piece 13 stores energy, and the clamping part 11 can be easily inserted into the through hole 31. After the elastic stop piece 13 passes through the through hole 31, the elastic stop piece 13 can release the stored energy and expand outward in the radial direction of the clamping part 11, and the elastic stop piece 13 abuts against the hole plate in the axial direction of the inner ring support 1, so that the inner ring support 1 is fixed relative to the hole plate through the abutting cooperation of the boss face 121 and the elastic stop piece 13 in the axial direction of the hole plate, and the inner ring support 1 is reliably fixed relative to the hole plate, and the sealing plug 10 is reliably fixed relative to the hole plate. Specifically, when the elastic stop piece 13 abuts against the hole plate in the axial direction of the inner ring support 1, it can press and deform the water stop part 23 to ensure the sealing effect of the sealing plug 10.

[0048] Referring to Figures 3-5 , Figure 7 and Figure 9In some embodiments of the utility model, the outer ring rubber 2 further comprises a reinforcing convex ring 24, the reinforcing convex ring 24 is connected to the axial surface of the main body part 21, the reinforcing convex ring 24 is annularly arranged, and the reinforcing convex ring 24 is arranged in a radial direction and spaced from the enclosing part 22. In this way, the structural strength of the main body part 21 can be improved, the deformation of the main body part 21 caused by stress can be reduced, the load bearing performance of the main body part 21 can be improved, the risk of rupture of the main body part 21 caused by stress can be reduced, and the reliability of the sealing plug 10 can be improved.

[0049] Referring to Figures 3-5 , Figure 7 and Figure 9 In some embodiments of the utility model, the outer ring rubber 2 further comprises a reinforcing convex rib 25, and the reinforcing convex rib 25 is at least two, for example, the reinforcing convex rib 25 can be two, three, four or more.

[0050] Referring to Figures 3-6 , Figure 8 and Figure 9 According to some optional embodiments of the utility model, the outer ring rubber 2 further comprises a lip 26, the lip 26 is connected to one end of the water stop part 23 away from the enclosing part 22, and in the direction away from the enclosing part 22, the lip 26 extends towards the radial outside of the clamping part 11. When the sealing plug 10 is clamped on the perforated plate 30, the lip 26 can abut on the perforated plate 30, the abutting distance between the outer ring rubber 2 and the perforated plate 30 is lengthened, the risk of water flowing from the water stop part 23 and the perforated plate 30 into the through hole 31 is effectively reduced, and the reliability of the sealing plug 10 is improved.

[0051] Referring to Figure 8 and Figure 9 In some optional embodiments of the utility model, in the direction away from the clamping part 11, the cross-sectional area of the lip 26 gradually decreases.
