The bottom housing 100 may be any carrier that needs to be installed with various electrical connectors, for example, in an LED display screen, the bottom housing may be a bottom housing for installing an LED lamp panel in a box assembly.

In the present embodiment, it is conceivable that the first seal ring and the second seal ring may be in various ring shapes, for example, in various closed ring shapes such as an annular shape, an elliptical ring shape, and a rectangular ring shape, and a known material such as rubber may be selected as the material of the first seal ring and the second seal ring.

Fig. 3 is a partial schematic view of bottom case 100 of fig. 1, fig. 4 is a cross-sectional view of first gasket 120, and the installation of first gasket 120 and first gasket 120 will be described in detail with reference to fig. 3 and 4, and with continued reference to fig. 2.

In some embodiments, in order to facilitate the first sealing ring 120 to be squeezed and deformed during installation, a first cavity 121 is formed in the first sealing ring 120 and extends annularly along the first sealing ring 120. That is, the first seal ring 120 has a cavity when viewed in cross section of the first seal ring 120.

In some embodiments, a first recess 124 is provided in the middle of the top of the first seal ring 120, extending annularly along the first seal ring 120. By providing the first recess 124, when the bottom case 100 is installed and the first gasket 120 is attached to a surface to be sealed, a gap is formed in the middle of the attached portion. The gap allows water that has permeated through the upper portion of the bonded portion of the first seal ring 120 to flow to the lower portion of the first seal ring 120 through the gap and to be finally discharged, whereby waterproof sealing can be performed more effectively.

In some embodiments, in order to conveniently and firmly mount the first packing 120, the bottom case 100 is provided with a first mounting protrusion 101 having a ring shape; first seal ring 120 has a first opening 122 extending annularly along first seal ring 120, and first mounting protrusion 101 is inserted into first opening 122 when first seal ring 120 is mounted to bottom case 100. Thereby, the first seal ring 120 can be easily and firmly fixed. It is contemplated that the first opening 122 may be provided to communicate with the first cavity 121, and the first mounting protrusion 101 may be inserted into the first cavity 121 to a depth that the first sealing ring 120 can be fixed without filling the first cavity 121 to have a sufficient deformation space for the first sealing ring 120.

In some embodiments, bottom case 100 is further provided with an annular first wall portion 102, first wall portion 102 is located on outer side 120a of first sealing ring 120, and height of first wall portion 102 is lower than height of first sealing ring 120. By providing first wall portion 102, water flow can be stopped to some extent and drained, and by providing first wall portion 102 at a height lower than that of first seal ring 120, it is ensured that first wall portion 102 does not interfere with a surface to be sealed after bottom case 100 is mounted. Further, the distance between the first wall portion 102 and the first mounting protrusion 101 may be set to be substantially the same as the wall thickness of the first opening 122 side of the first sealing ring 120, so as to clamp the first sealing ring 120 and more firmly fix the first sealing ring 120.

In some embodiments, in order to more firmly mount the first sealing ring 120, a plurality of first positioning blocks 103 are disposed at a side portion of the first wall portion 102, and correspondingly, a plurality of first positioning grooves 123 are disposed at the first sealing ring 120, and when the first sealing ring 120 is mounted to the bottom case 100, the first positioning grooves 123 are respectively fitted with the first positioning blocks 103. Accordingly, after the first gasket 120 is mounted on the bottom case 100, the first positioning blocks 103 can be engaged with the first positioning grooves 123, so that the first gasket 120 can be more firmly fixed and the first gasket 120 can be prevented from loosening.

In the above embodiment, although the first sealing ring 120 is mounted by the first mounting protrusion 101, the invention is not limited thereto, and the first sealing ring may be directly attached to the bottom case 100 by other methods, for example, by gluing, or may be mounted by forming a groove in the bottom case 100 and accommodating the first sealing ring in the groove.

Fig. 5 is a schematic view of a front view direction of the second seal ring 130, and fig. 6 is a schematic view of a rear view direction of the second seal ring 130; the second seal ring 130 and the attachment of the second seal ring 130 will be described in detail below with reference to fig. 5 and 6, and with continued reference to fig. 2 and 3.

In some embodiments, in order to conveniently and securely mount the second packing 130, the bottom case 100 is provided with an annular second mounting protrusion 104, the second packing 130 has a second opening 132 extending in an annular shape of the second packing 130, and the second mounting protrusion 104 is inserted into the second opening 132 when the second packing 130 is mounted to the bottom case 100. Thereby, the second seal ring 130 can be easily and firmly fixed.

In some embodiments, bottom case 100 further has an annular second wall portion 105, second wall portion 105 is located outside second sealing ring 130, and a height of second wall portion 105 is lower than a height of second sealing ring 130. By providing the second wall portion 105, water flowing to the upper portion of the second seal ring 130 can be partially received and guided downward. Further, the distance between the second wall portion 105 and the second mounting protrusion 104 may be set to be substantially the same as the wall thickness of one side of the second opening 132 of the second seal ring 130, so as to be able to clamp the second seal ring 130 and more firmly fix the second seal ring 130.

In some embodiments, in order to drain the water passing through the second sealing ring 130 more effectively, the lower portion of the second wall 105 is opened with a second notch 106, and the first notch 131 is communicated with the second notch 106. Thus, after passing over the second sealing ring 130, the water is isolated by the first sealing ring 120, and flows down along the ring structure of the first sealing ring 120, and is discharged at the first gap 131 and the second gap 106.

It is conceivable that the waterproof structure 400 of the interface of the present embodiment is suitable for the case of vertical installation or inclined installation, that is, the case where the first notch 131 is located at the lower portion of the first interface mounting portion 110. Therefore, in order to prevent the second seal ring 130 from being mounted to the upper portion of the first port mounting portion 110 due to an error in the assembly of the second seal ring 130, in some embodiments, the first notch 131 is provided with a first restriction member 133, the first restriction member 133 extends in a radial direction of the second seal ring 130, and after the second seal ring 130 is mounted to the second mounting protrusion 104, the first restriction member 133 extends into the second notch 106. Therefore, the first limiting piece 133 and the second notch 106 are matched, so that the second sealing ring 130 can be prevented from being reversely mounted, for example, because the second notch 106 is not formed on the upper portion of the second wall portion 105, when the second sealing ring 130 is reversely mounted, the first limiting piece 133 on the second sealing ring 130 interferes with the second wall portion 105, and the second sealing ring cannot be mounted.

The waterproofing process of the waterproof structure 400 of the interface is explained below.

The utility model discloses a waterproof construction 400 of interface for the condition of slope installation or vertical installation, first breach 131 is located the lower part. When the waterproof structure of the structure is exposed to water, for example, rain, water flows down from above the waterproof structure 400 of the interface, a part of which is blocked by the second wall 105 and flows out along the ring-shaped structure of the second wall 105. The water flow over the second wall 105 is blocked by the second sealing ring 130 and flows out along the ring-shaped structure of the second sealing ring 130. The water that has passed over the second sealing ring 130 is partially blocked by the first wall portion 102, and flows out through the first notch 131 along the annular structure of the first wall portion 102. The water that has passed over the first wall 102 is finally isolated by the first sealing ring 120 and flows out through the first notch 131 along the ring-shaped structure of the first sealing ring 120. This ensures waterproof performance in the first port mounting portion 110 surrounded by the first seal ring 120.
