Description
Technical field
The utility model belongs to a kind of navigating equipment field, is specifically related to a kind of marine magnetic compass rose.
Background technology
Traditional magnetic compass generally all comprises sieve basin, and described sieve basin is provided with the chamber of corrugated tube and two storage liquid, and described two chambers distribute up and down, make two chamber by corrugated tube; Liquid can expand with heat and contract with cold therefore easily produce bubble when the temperature is changed, because the caliber of corrugated tube is comparatively large, described bubble flows to another top chamber from the chamber of bottom through corrugated tube, thus affects magnetic compass precision.
Utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model to prevent the liquid of magnetic compass inside from producing bubble.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of marine magnetic compass rose, include sieve basin, described sieve basin includes liquid container, compass bowl, axonometer assembly, kapillary, upper glassy layer, intermediate glass layer, verge ring, pressure ring and multiple screw, described upper glassy layer and intermediate glass layer lay respectively at the both sides up and down of compass bowl, and the O-ring seal making both seal all is set between upper glassy layer and compass bowl and between intermediate glass layer and compass bowl, described verge ring is positioned at the upside of glassy layer, and to be connected by screw with compass bowl and to make verge ring, upper glassy layer, fixing between O-ring seal and compass bowl, described liquid container the downside of intermediate glass layer and and intermediate glass layer between be provided with make both sealing O-ring seal, described pressure ring and compass bowl are connected by screw and make compass bowl, intermediate glass layer, pressure ring, fixing and be the chambers that cut-off rule forms two sealings with intermediate glass layer between O-ring seal and liquid container, described axonometer component sealing is plugged in intermediate glass layer and makes kapillary 2 chamber.
Further also comprise nut, described nut is positioned at the lower rear flank of intermediate glass layer and spins with axonometer assembly axonometer assembly and intermediate glass layer are tightly connected mutually.
The both sides up and down of described intermediate glass layer be provided with make intermediate glass layer respectively with the O-ring seal of axonometer assembly and nut seal.
The aperture of described kapillary is 0.5mm.
The upper end bending of described kapillary.
The material of described kapillary is copper.
(3) beneficial effect
Marine magnetic compass rose of the present utility model, compass is provided with two chambers, and by kapillary by two chamber, because the aperture of kapillary is little, liquid and intercapillary adhesion are greater than the cohesion of liquid itself, so liquid by capillary flow in the chamber at top, therefore cannot can not affect the precision of marine magnetic compass rose because of the gas produced that expands with heat and contract with cold, use more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of marine magnetic compass rose of the present utility model;
Fig. 2 is the structural representation of compass in Fig. 1;
Fig. 3 is the vertical view in Fig. 1;
1 be sieve basin, 2 be liquid container in figure, 3 be compass bowl, 4 be axonometer assembly, 5 be kapillary, 6 be upper glassy layer, 7 be intermediate glass layer, 8 be verge ring, 9 be pressure ring, 10 be nut, 11 be screw, 12 for O-ring seal.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in figures 1 and 3, a kind of marine magnetic compass rose, inside includes sieve basin 1.
As shown in Figure 2, described sieve basin 1 includes liquid container 2, compass bowl 3, axonometer assembly 4, kapillary 5, upper glassy layer 6, intermediate glass layer 7, verge ring 8, pressure ring 9 and multiple screw 11, described upper glassy layer 6 and intermediate glass layer 7 lay respectively at the both sides up and down of compass bowl 3, and the O-ring seal 12 making both seal all is set between upper glassy layer 6 and compass bowl 3 and between intermediate glass layer 7 and compass bowl 3, described verge ring 8 is positioned at the upside of glassy layer 6, and to be connected by screw 11 with compass bowl 3 and to make verge ring 8, upper glassy layer 6, fixing between O-ring seal 12 and compass bowl 3, described liquid container 2 the downside of intermediate glass layer 7 and and intermediate glass layer 7 between be provided with make both sealing O-ring seal 12, described pressure ring 9 and compass bowl 3 are connected by screw 11 makes compass bowl 3, intermediate glass layer 7, pressure ring 9, fixing and with intermediate glass layer 7 for cut-off rule forms two chambers sealed between O-ring seal 12 and liquid container 2, the chamber on upper strata places sieve basin instrument used as effect, the chamber of downside is used for storing liquid, described kapillary 5 is arranged on axonometer assembly 4, and aperture is 0.5mm, material is copper, upper end bending, described axonometer assembly 4 sealing is plugged in intermediate glass layer 7 and makes kapillary 52 chamber, because the aperture of kapillary 5 is little, adhesion between liquid and kapillary 5 is greater than the cohesion of liquid itself, so liquid by capillary flow in the chamber at top, therefore cannot can not affect the precision of marine magnetic compass rose because of the gas produced that expands with heat and contract with cold, navigate more accurate.
Described axonometer assembly 4 includes the nut 10 coordinated with it, and described nut 10 is positioned at the lower rear flank of intermediate glass layer 7 and spins with axonometer assembly 4 axonometer assembly 4 and intermediate glass layer 7 are tightly connected mutually.The both sides up and down of described intermediate glass layer 7 are provided with the O-ring seal 12 that intermediate glass layer 7 is sealed with axonometer assembly 4 and nut 10 respectively.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
