Detailed Description
In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The present invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1, fig. 1 is a structural diagram of the present invention, a dual sealing structure, including a first connecting member 1 and a second connecting member 2, a sealing surface of the first connecting member 1 and a sealing surface of the second connecting member 2 are oppositely disposed, the sealing surface of the first connecting member 1 is provided with a first stepped step 102, the sealing surface of the second connecting member 2 is provided with a second stepped step 202, and the first stepped step 102 and the second stepped step 202 are both three stepped steps, and are oppositely disposed; the three-step ladder-shaped steps are respectively a first step, a second step and a third step from one end to the other end; the first sealing strip 3 is arranged on the 1 st step of the first connecting piece 1 and the corresponding step of the second connecting piece 2 to form a first seal for blocking most of outside water; a second sealing strip 4 is arranged at the position of the 3 rd step of the first connecting piece 1, which corresponds to the step of the second connecting piece 2, so as to form a second seal for blocking a small amount of water in the water passing channel 5; the space between the first sealing strip 3 and the second sealing strip 4 forms a water passing channel 5, and a liquid leaking hole 6 or an end surface opening is arranged in the water passing channel 5 and used for leading out a very small amount of water entering from the first sealing strip 3.
If the whole sealing structure is a closed loop, see fig. 4, fig. 4 is a structural diagram of another embodiment of the present invention, the lowest part of the water passage 5 is provided with the liquid leakage hole 6, and a small amount of water is discharged from the liquid leakage hole 6 when entering the water passage 5.
If the whole sealing structure is not an end-to-end closed loop, see fig. 5, the whole sealing is broken at the port, the water passing channel 5 is an end face opening, and the end face opening needs to be arranged at the lower part or the side part of the product for discharging water.
The first connecting piece 1 and the second connecting piece 2 are two products which need to be sealed, such as doors and frames, covers and boxes and the like which need to be sealed.
Referring to fig. 2 and 3, fig. 2 and 3 are respectively a structure diagram of a first connecting piece and a second connecting piece of the present invention, a first waterproof boss 101 is arranged on an end surface of a sealing surface of the first connecting piece 1, a draft angle is arranged on a large surface of the first connecting piece, a second waterproof boss 201 is arranged on an end surface of a sealing surface of the second connecting piece 2, and a draft angle is arranged on a large surface of the second connecting piece; the water accumulation and rain area of the waterproof boss are small, and the amount of water required to be sealed is reduced; the setting of drawing die angle makes the product big face have certain slope, has certain slope when drenching with rain to avoid big face to have ponding, and is preferred, slope more than or equal to 0.5.
The first sealing function is mainly to seal and block a large amount of water from the outside, and the first sealing function is to block most of water. If have little water to get into in first seal, then can directly get into the water channel that forms, through the leading-in product outside of water channel, the second is sealed then only need sealed little water just can to this reaches double seal's effect, all has fine effect to waterproof dustproof.
The above contents are only for explaining the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical solution according to the technical idea of the present invention all fall within the protection scope of the claims of the present invention.
