Abstract
The utility model discloses a big dipper antenna host computer, including base, lid, and be located first sealing washer, the second sealing washer between base and the lid. Wherein make the kneck obtain good airtight protection through two sealing washers, and first sealing washer is higher than second sealing washer formation staggered floor seal structure. The infiltration that has completely cut off steam of the very big degree of structure of this kind of staggered floor.
Description
Technical field
This utility model relates to the field of antenna main machine structure design.
Background technology
At present, the most perfect along with the networking of novel Beidou II satellite and Beidou II networking, Beidou satellite navigation and application service have obtained unprecedented development.Big Dipper performance, as core component in Big Dipper equipment, is played key effect by antenna.
Because antenna is chronically at open-air conditions, it is desirable to its under various complex environments can life-time service, particularly in humidity, sleet and salt fog weather.Antenna main frame generally comprises Anneta module and relevant circuit part, and the combination that in structure, many employings fasten up and down, this kind of combination largely determines the water resistance of whole antenna.For the antenna of this mode that combines between the higher and lower levels, general solution be take screw to press to make top and the bottom are airtight fits and coordinates waterproof grommet to reach corresponding waterproof effect.This combination can make O-ring seal unbalance stress, and the sealing ring that stress is gently located also exists infiltration hidden danger.
Utility model content
The purpose of this utility model is to provide a kind of Beidou antenna main frame improving waterproof sealing effect.
A kind of Beidou antenna main frame, including base, the lid covered on base；Described base has the sidewall surrounding host cavity, and described sidewall has upper surface, and this upper surface is provided with the first accepting groove；And the inner side of sidewall is provided with stage portion, the end face of this stage portion is provided with the second accepting groove；Also include the first sealing ring being contained in the first accepting groove, the second sealing ring being contained in the second accepting groove；The position of described first sealing ring is higher than the second sealing ring, and the position of the second sealing ring is positioned at inside the first sealing ring；Described lid is provided with and the bottom surface, outer ring of wall upper surface laminating, and described first sealing ring is attached between described upper surface and bottom surface, outer ring；Described lid is additionally provided with the inner ring bottom surface of the end face laminating with stage portion, and described second sealing ring is attached between described end face and inner ring bottom surface.
Compared with prior art, Beidou antenna main frame of the present utility model makes seam obtain good closed protective by two different O-ring seals；Including the first sealing ring and be positioned at the second sealing ring inside the first sealing ring, and the first sealing ring forms staggered floor higher than the second sealing ring and seals structure.The structure of this staggered floor has completely cut off the infiltration of steam significantly.
Accompanying drawing explanation
Fig. 1 is the stereochemical structure exploded view of this utility model Beidou antenna main frame.
Fig. 2 is the first sealing ring and the schematic cross-section of the second sealing ring part in this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings technical scheme is described further.
Incorporated by reference to shown in Fig. 1 and Fig. 2, the open a kind of Beidou antenna main frame of this utility model, including base 1, the lid 2 covered on base.Described base 1 has the sidewall 11 surrounding host cavity.Described sidewall 11 is provided with line inlet 17 for circuit (not shown) and the connection of the electronic component (not shown) of placement in host cavity.In the present embodiment, owing to whole main frame is cylinder design, therefore described sidewall 11 is to form ring-type sidewall.Described sidewall 11 has upper surface 12, and this upper surface 12 is provided with the first accepting groove 13.And the inner side of sidewall 11 is provided with stage portion 14, the end face of this stage portion 14 is provided with the second accepting groove 16.And preventing steam from entering to provide sealing property, this Beidou antenna main frame also includes the first sealing ring 3 being contained in the first accepting groove 13, the second sealing ring 4 being contained in the second accepting groove 16.The position of described first sealing ring 3 is higher than the second sealing ring 4, and the position of the second sealing ring 4 is positioned at inside the first sealing ring 3.Wherein seal structure owing to the first sealing ring 3 forms staggered floor higher than the second sealing ring 4.The structure of this staggered floor has completely cut off the infiltration of steam significantly and has improved waterproof sealing performance.
Wherein in order to coordinate with the sealing of first, second sealing ring.Described lid 2 is provided with and the bottom surface, outer ring of wall upper surface 12 laminating, and described first sealing ring 3 is attached between described upper surface and bottom surface, outer ring；Described lid 2 is additionally provided with the inner ring bottom surface of the end face laminating with stage portion, and described second sealing ring 4 is attached between described end face and inner ring bottom surface.
Wherein, owing to whole main frame is cylindrical structure, in order to adapt to this structure, described first accepting groove 13 and the second accepting groove 16 are annular；Described first sealing ring 3 is flat annular ring, and described second sealing ring 4 is circular or oval annular ring for cross section.And the outward flange of described first sealing ring 3 is provided with some recesses 31 extended internally for avoiding the interference with screw.This screw is the screw being fixed together with base 1 by lid 2.So screw will not act directly on the first sealing ring 3, reduces the impact that the force inequality of screw is brought.
