The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in Fig. 2, a kind of withstand voltage illuminating lamp shade under water, comprise pressure hull 1, described pressure hull 1 comprises cylindrical shell 11, described cylindrical shell 11 is extended with top cover 12 to its inside, on described top cover 12, be provided with through hole, described through hole is provided with withstand voltage water-tight electrical connector 2, on described withstand voltage water-tight electrical connector 2, lamp socket 3 is installed, described lamp socket 3 is positioned at cylindrical shell 11, the inwall of described cylindrical shell 11 is extended with annular boss 13, described cylindrical shell 11 is provided with O RunddichtringO 4 with the corner that engages of annular boss 13, described O RunddichtringO 4 is close on cylindrical shell 11 and annular boss 13, the inner wall sleeve of described cylindrical shell 11 is connected to withstand voltage glass 5, withstand voltage glass 5 integral body are cylindricality, thereby described withstand voltage glass 5 is provided with chamfering on this formation sealing inclined-plane 51, chamfering place near one end of O RunddichtringO 4, the sealing inclined-plane 51 of described withstand voltage glass 5 is connected on O RunddichtringO 4.Preferably, the chamfer angle on described withstand voltage glass 5 is 45 °, is convenient to like this seal the processing on inclined-plane 51, is also conducive to seal inclined-plane 51 and coordinates better and reach sealing effectiveness with O RunddichtringO 4.In addition, described withstand voltage glass 5 is actively socketed on the inwall of cylindrical shell 11, between described withstand voltage glass 5 and annular boss 13, forms and is convenient to the gap that withstand voltage glass 5 moves.The external diameter of withstand voltage glass 5 is slightly less than the internal diameter of cylindrical shell 11, so that withstand voltage glass 5 is fit in cylindrical shell 11, is also convenient to withstand voltage glass 5 and moves to push O RunddichtringO 4 simultaneously.The setting in gap also contributes to withstand voltage glass 5 to move extruding O RunddichtringO 4, to have guaranteed better sealing effectiveness.
Described cylindrical shell 11 is useful on and prevents that water is from flowing to the sealing gasket 6 of cylindrical shell 11 between cylindrical shell 11 and withstand voltage glass 5 away from one end fixed installation of annular boss 13.Preferably, described sealing gasket 6 is provided with illuminating lamp shade compact heap 7 away from one end of cylindrical shell 11, on described illuminating lamp shade compact heap 7, housing screw 8 is installed, housing screw 8 is connected to the end of cylindrical shell 11, thereby illuminating lamp shade compact heap 7 and sealing gasket 6 are fixed on cylindrical shell 11, and the quantity of described housing screw 8 is preferably more than four.Described sealing gasket 6 and illuminating lamp shade compact heap 7 are annular, and described sealing gasket 6 covers the gap between cylindrical shell 11 and withstand voltage glass 5.The effect of sealing gasket 6 and illuminating lamp shade compact heap 7, the one, can prevent that withstand voltage glass 5 from skidding off in cylindrical shell 11, the 2nd, can assist the effect of playing sealing, can infilter in cylindrical shell 11 by effectively anti-sealing.
Further, described sealing gasket 6 all equates with internal diameter and the external diameter of illuminating lamp shade compact heap 7, is provided with like this and helps save material, and contribute to the movement of withstand voltage glass 5, and sealing gasket 6 and compact heap 7 can not hinder the pressure-bearing of withstand voltage glass 5.
During use, first O RunddichtringO 4 is put into the pressure hull 1 of illuminating lamp shade, then withstand voltage glass 5 is put into pressure hull 1, and made sealing inclined-plane 51 push down O RunddichtringO 4, with sealing gasket 6 and illuminating lamp shade compact heap 7, withstand voltage glass 5 and O RunddichtringO 4 are compressed again afterwards.Sealed characteristic due to withstand voltage glass 5 and O RunddichtringO 4, when the pressure bearing when illuminating lamp shade increases gradually, withstand voltage glass 5 is more pressed tighter by O RunddichtringO 4, this makes illuminating lamp shade when bearing elevated pressures, also have good water proofing property and seal, when the pressure bearing when illuminating lamp shade reduces gradually, the thrust of 5 pairs of O RunddichtringOs 4 of withstand voltage glass also reduces gradually.
In illuminating lamp shade, install after illuminating lamp, illuminating lamp shade is placed in cabin, and whole illuminating lamp shade is immersed in the water in cabin; Can one camera be set on illuminating lamp side, for taking the instrument working condition in cabin, during illuminating lamp illumination, staff also can watch the situation in cabin by other observation window.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
