The utility model provides a kind of sealing structure that antenna house is connect with matrix, including antenna house, matrix and sealing spiral shell
Mother, the antenna house include cover and the interconnecting piece set on cover free end, and the interconnecting piece is cylindrical, described matrix socket
In in the interconnecting piece, the inner peripheral surface of the interconnecting piece is equipped with multiple first annular grooves, in the first annular groove
Equipped with sealing ring, the outer circumference surface of described matrix is equipped with first annular boss, and the outer circumference surface of the interconnecting piece is equipped with the second ring
Connected in star, the inner peripheral surface at the sealing nut both ends are respectively equipped with the second annular convex platform and third annular convex platform, and described second
Annular convex platform is stuck in the side-walls of the first annular boss, and the third annular convex platform and the second annular groove match
It closes.
Wherein it is preferred to which the outer circumference surface of the first annular boss is flushed with the outer circumference surface of the interconnecting piece.
Wherein it is preferred to which institute's antenna house and described matrix are fixed by jackscrew.
Wherein it is preferred to which the middle part of the sealing nut inner peripheral surface, which is equipped with annular, reinforces platform.
Wherein it is preferred to which the free end that the annular reinforces platform contradicts on the outer wall of the interconnecting piece.
The utility model has the beneficial effects that
The utility model the junction of antenna house and matrix be equipped with sealing nut, avoid the source of corrosion such as rainwater, moisture into
Enter passway, and be externally provided with sealing ring in the connection of antenna house and matrix, sealing effect is good, can be well protected antenna.And
The mounting surface of sealing nut is vertical with socket direction, in repeated disassembled and assembled, will not wear sealing nut, not need after dismounting
Sealing material is refilled, is installed convenient for disassembly and assembly.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific embodiment
Below in conjunction with the utility model specific embodiment, the technical solution of the utility model is carried out clearly and completely
Description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is based on
The embodiments of the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all
Other embodiments are fallen within the protection scope of the utility model.
As depicted in figs. 1 and 2, the present embodiment provides the sealing structures that a kind of antenna house is connect with matrix, including antenna house
1, matrix 2 and sealing nut 3, antenna house 1 include cover 1-1 and the interconnecting piece 1-2 set on the free end cover 1-1, interconnecting piece 1-2
Cylindrical, matrix 2 is socketed in interconnecting piece 1-2, is set on the inner peripheral surface of interconnecting piece 1-2 there are two first annular groove 4, the
