Referring to Fig. 1 and Fig. 2, a kind of antenna water-proof structure of the utility model embodiment offer, including antenna casing, and day
Line shell includes the first sealing 1 and the second sealing 2, passes through the fit structure shape of the first sealing 1 and the second sealing 2
Into waterproof effect, specifically the first sealing 1 has fluting 11, and the second sealing 2 has rib 21, in the first sealing 1
When coordinating installation with the second sealing 2, rib 21 is extending at least partially into fluting 11, so that the first sealing 1 and second
There is part-structure overlapping between sealing 2, sealing strip 3 is arranged between the side wall of rib 21 and fluting 11, it is close by this
Strip of paper used for sealing 3 causes clamping between rib 21 and fluting 11, and sealing strip 3 has bending structure 311, and the bending structure 311 along first
The direction of sealing 1 to the second sealing 2 bends extension successively, and the break of the both sides of bending structure 311 abuts fluting 11 respectively
Inwall and rib 21 outer surface, can be wavy or zigzag for bending structure 311, two kinds of structures are similar,
To play preferable sealing effectiveness.In the utility model, the summit of the both sides of bending structure 311 of sealing strip 3 abuts fluting respectively
11 side wall and the outer surface of rib 21, so that the side wall and rib 21 of the both sides of bending structure 311 and fluting 11
It is interference fit between outer surface, on the premise of structure clamping is ensured, smaller, side rigging error is influenceed by fit-up gap
The sealing effectiveness of opposite side can be increased, on the premise of installation difficulty is reduced, also well increase sealing compression joint area, and then
Improve waterproof reliability.
Referring to Fig. 2 and Fig. 3, further, the structure of sealing strip 3 is refined, it includes two Access Divisions being oppositely arranged
31 and the connecting portions 32 of two Access Divisions 31 is connected, enclose to form the first U-type groove 33, the i.e. section of sealing strip 3 between three
Approximate U-shaped, two Access Divisions 31 are respectively provided with above-mentioned bending structure 311, and the sealing strip 3 of this structure is placed in fluting 11,
The rib 21 of second sealing 2 is arranged in the first U-type groove 33 of sealing strip 3.In the present embodiment, connecting portion 32 and fluting 11
Bottom wall is corresponding, and connecting portion 32 is clamped in by rib 21 on the bottom wall of fluting 11, and two of two Access Divisions 31 and fluting 11
Opposing sidewalls are corresponding, two Access Divisions 31 are clamped in the side wall of fluting 11 by rib 21, on two Access Divisions 31
Bending structure 311 is provided with, then two bending structures 311 are oppositely arranged, when error occurs in assembling, wherein a bending structure
311 are unclamped, then another bending structure 311 is compacted, i.e., can at least ensure the close of the wherein side of rib 21 in this way
Seal effect.Certain connecting portion 32 is formed in one with two Access Divisions 31 to be made, and sealing strip 3 is an overall structure, and it can be with
For silicon rubber bar, be made of silicon rubber, sealing strip 3 has certain plasticity, further strengthen rib 21 with fluting 11 it
Between sealing effectiveness.
