Further, the cross section of described cap rubber ring is T-shaped, and lower end is to both sides projection, and shell rubber ring upper end is provided with the recess mating with cap rubber ring lower end, and cap rubber ring lower end is connected in the recess of shell rubber ring.
Further, described cap is the cap that antiultraviolet material is made.
Further, the amplitude that described shell sectional area reduces reduces successively under upper, and lower end cross-sectional area reduces to change mild.
The utility model compared with prior art, have the following advantages and effect: between the shell of GNSS measurement antenna and cap, be connected and fixed by buckle, the convenience that can avoid like this corrosion and operate very, be convenient to inner antenna element to safeguard, simultaneously at cap and shell connecting portion, seal is set, when cap and shell are connected and fixed, waterproof anti-corrosion effect can be further strengthened in the sealing of the rubber ring by seal like this.
Brief description of the drawings
Fig. 1 is the schematic diagram that GNSS of the present utility model measures antenna.
Fig. 2 is the front view that GNSS of the present utility model measures antenna.
Fig. 3 is the partial enlarged drawing that GNSS of the present utility model measures antenna.
Embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but specific embodiment given applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to overall structure do form and immaterial conversion all should be considered as the protection range that the technical solution of the utility model limits.
As shown in Figure 1 or 2, GNSS of the present utility model measures antenna package containing shell 1, cap 2 and antenna element is in the enclosure set.Shell 1 is the hollow revolving body shell of sectional area from reducing gradually under upper, and the amplitude that shell 1 sectional area reduces reduces successively under upper, lower end cross-sectional area reduces to change mild, thereby formation mushroom can effectively be avoided the invasion and attack of rainwater to shell lower end connecting portion like this in rainy environment.The upper side edge of shell 1 is along being provided with upwardly extending annular edge along 3, annular edge equates with cap 2 internal diameters along 3 external diameter, the annular edge that cap 2 is socketed in shell 1 upside has buckle 4 along 3 outsides and along the circumferential spaced set of cap 2, as shown in Figure 3, buckle 4 comprises and is fixed on the wedge shape fixture block 5 of cap inner side and is arranged on the vertical channel 6 of annular edge along outside, the lower end of vertical channel 6 is provided with the depression 7 to annular edge along inner side, when cap 2 laminating on shell 1 time, wedge shape fixture block 5 is along vertical channel 6 down slidings, last wedge block 5 is stuck in depression 7 places and fixes.Cap 2 and shell 1 connecting portion inner side are also provided with seal 8, seal 8 comprises cap draw-in groove 9, shell draw-in groove 10, cap rubber ring 11 and shell rubber ring 12, cap draw-in groove 9 and shell draw-in groove 10 are annular slot, cap draw-in groove 9 outsides are fixed on cap 2 inner sides, the annular edge that shell draw-in groove 10 outsides are fixed on shell 1 is along inner side, cap rubber ring 11 is connected to cap draw-in groove 9 lower ends, shell rubber ring 12 is connected to shell draw-in groove 10 upper ends, and cap rubber ring 11 and shell rubber ring 12 intermeshing.The cross section of cap rubber ring 11 is T-shaped, and lower end is to both sides projection, and shell rubber ring 12 upper ends are provided with the recess mating with cap rubber ring 11 lower ends, and cap rubber ring 11 lower ends are connected in the recess of shell rubber ring 12.Cap 2 is in being pressed on shell 1 like this, and cap rubber ring 11 lower ends are connected in shell rubber ring 12 simultaneously, like this can two intermeshing sealings of rubber ring, can form effective sealing, and greatly improve the waterproof anti-corrosion ability of antenna.In order to allow cap rubber ring 11 can more successfully stick in shell rubber ring 12, in selection, cap rubber ring 11 is selected the harder rubber of quality simultaneously, and 12 of shell rubber rings are selected the softer rubber of quality.
