Description
Technical field
The present invention relates to a kind of light fitting sealing structure, particularly a kind of outdoor lamp sealing device adopting anti-aging special-shaped seal ring.
Background technology
Along with the raising that outdoor use lamp requires for degree of protection, light fixture sealing has become the difficult problem that light fixture manufacturer must capture.Current general groove sealing ring or sealing strip being placed in lamp base of light fixture sealing, then with bolt or alternate manner, base and cover plate are fixed, make it the effect reaching sealing.This technique relies on bolt base and cover plate to be fixed together, bolt is fixing tighter, gap between base and cover plate is less, sealing ring or sealing strip are out of shape larger, sealing ring or sealing strip and the gap between base and cover plate less, when enough hour of gap, the effect of sealing just can be played.Light fixture service life, along with light fixture extends service time, sealing ring or sealing strip just there will be aging, and its sealing property will reduce greatly, just there will be the situation of the dust that leaks, enters with light fixture out of doors under atrocious weather generally more than 5 years.
Chinese patent 200910110515.6 discloses a kind of outdoor lamp sealing device adopting anti-aging special-shaped seal ring, which discloses the sealing ring that a kind of cross section is special shape, has hollow hole in the middle of this cross section.Special-shaped seal ring is fitted tightly with the two by compressive strain by assembling by lamp housing and cover/cover and Transparent Parts respectively, and sealing circle sealing area is larger than traditional o RunddichtringO, good seal performance; Gas regulation in hollow hole enables the change of sealing ring adaptive temperature, enhances the anticorrosive life-span of sealing ring.
Chinese patent 200910110139.0 discloses a kind of profiled seal bar preventing reversing, be shifted.Special-shaped sealing strip comprises trapezoid and inverted trapezoidal along the cross section perpendicular to length direction, is installed with coordinating of seal groove by sealing strip, realizes sealing strip installation, accurate positioning, is not easy to reverse, be shifted; And can ensure that special-shaped sealing strip reaches the reasonable thrust needed for seal request, thus lighting sealing is made to reach IP requirement of shelter.
But, the hermetically-sealed construction that above-mentioned patent provides, still there will be problem, concrete reason is as follows:
1. between sealing ring and lamp body, gap is excessive, and the gap between base and cover plate does not seal up by sealing ring completely, causes entering (water, particle etc.) of harmful substance;
2. light fixture uses through long-time, and set bolt can become loosening, and sealing ring and the gap between cover plate and base will become large, and loosening appears in sealing ring, causes sealing property to weaken;
3. installation light fixture is in the presence of a harsh environment after using for a long time, and sealing ring there will be aging even damaged situation, causes sealing property to weaken.
Summary of the invention
Object of the present invention is exactly in view of the foregoing defects the prior art has, a kind of outdoor lamp sealing dress adopting anti-aging special-shaped seal ring is provided, by the special construction of base and sealing ring, sealing ring has been sealed in inside grooves completely, hardly with extraneous contact, prevent the aging of sealing ring, and then ensure that its sealing property.
A kind of outdoor lamp sealing device adopting anti-aging special-shaped seal ring that the present invention mentions, its technical scheme comprises cover plate, special-shaped seal ring and base, and special-shaped seal ring parcel is realized anti-aging sealing by cover plate and base; Described cover plate comprises cover plate main body and cover plate is protruding, and described cover plate main body is circular configuration, and the below at circumferential edges place is provided with the cover plate projection of annular;
Described special-shaped seal ring is cirque structure, comprise sealing ring hollow bulb, sealing ring two side, arcuate projections outer edge, sealing ring protuberance, the centre of described sealing ring two side is provided with the sealing ring hollow bulb with cover plate male cooperation, the open top of sealing ring hollow bulb, remain silent in bottom; The bottom of described sealing ring two side is sealing ring protuberance, and the cross section of sealing ring protuberance is arcuate structure, and the both sides of sealing ring protuberance are arcuate projections outer edge, for base engagement;
Described base comprises o-ring groove, base body, arc groove, and described base body is cirque structure, and the center of base body is provided with the o-ring groove of a circle for being connected with sealing ring, and the bottom of described o-ring groove is arc groove.
The bottom of above-mentioned sealing ring hollow bulb is the lower arcuate surface that rubber is made, and is out of shape under the compressing of cover plate projection.
The above-mentioned horizontal length of arcuate projections outer edge is identical with the horizontal length of the arc groove of base.
Above-mentioned arcuate projections outer edge and sealing ring protuberance Formation cross-section are crescent structure, and are that crescent cavity matches with the cross section of the arc groove on base.
In addition, the outside of above-mentioned sealing ring two side is provided with the projection of many group arcs, can strengthen its sealing effectiveness.
A kind of using method adopting the outdoor lamp sealing device of anti-aging special-shaped seal ring that the present invention mentions, its technical scheme comprises as follows:
(1), be enclosed within the cover plate projection of cover plate by special-shaped seal ring entirety, cover plate is protruding overall to be inserted in sealing ring hollow bulb, and the lower arcuate surface that rubber is made is pushed down in the bottom of cover plate projection, and under the compressing of cover plate projection, distortion realizes sealing;
(2), be pressed in o-ring groove corresponding to base by overlapping the cover plate protuberance having sealing ring, by cover plate protuberance indentation sealing circle groove, guarantee that o-ring groove is inserted completely in the sealing ring two side of sealing ring, and arcuate projections outer edge and o-ring groove bottom space are stuck, and arcuate projections outer edge and sealing ring protuberance Formation cross-section are crescent structure, realize sealing;
(3), press-in after, with fixed screw, cover plate is fixed on base, thus by special-shaped seal ring by cover plate and base entirety parcel realize anti-aging sealing.
Beneficial effect of the present invention is specific as follows:
(1) material (water, air plankton etc.) affecting its life-span if touch in light fixture use procedure, this material can first touch the sealing ring not being pressed into groove, by the stop of this place's sealing ring, enter into inside hardly, even if there is a small amount of material to enter into inside grooves, because groove is shut by the sealing ring protuberance bottom sealing ring, material just can not enter into lamp body inside.
(2) loosened screw is prevented, light fixture uses through long-time, unavoidable meeting loosened screw, after sealing ring protuberance provided by the invention stretches into the bottom portion of groove space corresponding with it, the arc groove (3.3) that its arcuate projections outer edge is corresponding with sealing ring protuberance with bottom portion of groove is stuck, even if fixed screw has loosening, sealing ring also can not get loose easily, still well can play sealing function.
