It rings, there are dynamic changes for the intracorporal pressure of chamber, and the internal and external pressure difference of generation impacts plastic shell for a long time plastic shell occurs
Cracking or deformation.
Though existing antenna casing has the leakproofness for improving antenna using buckle and rubber ring combination, due to that can not arrange
Gas, can generate destructive power to shell due to long-term pressure difference after connecting in this way makes product lose leakproofness, still has part infiltration
Water.Except guaranteeing also to need to account for its gas permeability while antenna casing leakproofness, if gas permeable devices setting is unreasonable,
Such as be arranged in shell bottom centre, due to being actually needed, there may be the operations for hindering gas permeable devices ventilative during installation.Therefore,
Need to fully consider the leakproofness and gas permeability of shell in the setting of measurement type external antenna shell.
Utility model content
The main purpose of the utility model is to propose a kind of measurement type antenna casing, it is intended to by antenna housing outer layer zone

Time can play the due characteristic of water-proof ventilated device, and the risk that shell cracks is minimized, the use of antenna casing is improved
Performance and used life.
To achieve the above object, the utility model proposes measurement type antenna casing, including face-piece, bottom case, gas permeable devices,
The face-piece is mounted on the bottom case, forms the cavity for accommodating antenna element, and the bottom case upper surface is set along its circumferential direction
There is an annular groove, the face-piece is equipped with the annular convex platform being adapted to the annular groove, the annular convex platform and the ring
Connected in star grafting, and sealing element is filled in the annular groove；The bottom case surface circumferentially also has additional several be used for along it
The counterbore of fastening screw is worn, the counterbore is uniformly distributed along the lateral surface of the annular groove, and the face-piece is equipped with to sink with described
One-to-one several threaded holes, the face-piece are fixedly connected with the bottom case by fastening screw respectively in hole；The bottom case bottom
Face center is equipped with one for installing the mounting portion of support rod, and the bottom case bottom surface also wears a gas permeable devices, the gas permeable devices
It is installed between the mounting portion and the annular groove.
Preferably, the port surface of the annular groove is arranged higher than the bottom case upper surface.
Preferably, the sealing element is set as sealant.
Preferably, the gas permeable devices are set as a ventilative screw, and the ventilative screw is in the hollow setting of " T " type, described
The T-type end of ventilative screw is equipped with ventilated membrane.
Technical solutions of the utility model guarantee the close of antenna casing by using the mode of antenna housing and seal combination
Feng Xing, while gas permeable devices are set on antenna bottom case.In practical applications, gas permeable devices can play waterproof and balance pressure always
The effect of power, the influence by pressure change to product casing minimize, and guarantee the reliability of sealing structure.
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
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the utility model measurement type antenna casing the schematic diagram of the section structure；
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
The utility model proposes measurement type antenna casing.Including face-piece 1, bottom case 2, gas permeable devices, the face-piece 1 is installed
On the bottom case 2, the cavity for accommodating antenna element is formed, it is recessed that 2 upper surface of bottom case along it is circumferentially with an annular
Slot 3, the face-piece 1 are equipped with the annular convex platform 4 being adapted to the annular groove 3, the annular convex platform 4 and the annular groove
3 grafting, and sealing element 7 is filled in the annular groove 3；2 surface of bottom case circumferentially also has additional several for wearing along it
If the counterbore of fastening screw 5, the counterbore is uniformly distributed along the lateral surface of the annular groove 3, and the face-piece 1 is equipped with to sink with described
One-to-one several threaded holes, the face-piece 1 are fixedly connected with the bottom case 2 by fastening screw 5 respectively in hole；The bottom case
2 bottom center are equipped with one for installing the mounting portion 6 of support rod, and 2 bottom surface of bottom case also wears a gas permeable devices, described ventilative
Device is installed between the mounting portion 6 and the annular groove 3.
Further, the port surface of the annular groove 3 is arranged higher than 2 upper surface of bottom case.
Further, the sealing element 7 is set as sealant, and the material of the sealant can be rubber, or
Silica gel.
Antenna face-piece 1 and bottom case 2 can be pressed directly, are fixedly connected by face-piece 1 with the screw of 2 periphery of bottom case, protected simultaneously
Annular convex platform 4 on card face-piece 1 is abutted with the sealant in 2 annular groove 3 of bottom case, and antenna element is placed on 1 He of antenna face-piece
In the cavity that bottom case 2 is formed, antenna is fixed on support rod entirely through the mounting portion 6 at 2 center of bottom case.Antenna housing assembly is tight
