[0006] 1. The gap between the sealing ring and the lamp body is too large, and the sealing ring does not completely seal the gap between the base and the cover, resulting in the entry of harmful substances (water, particles, etc.);
[0007] 2. After long-term use of the lamp, the fixing bolts will become loose, the gap between the sealing ring and the cover plate and the base will become larger, and the sealing ring will become loose, resulting in weakened sealing performance;
[0008] 3. After a lamp installed in a harsh environment is used for a long time, the sealing ring will be aged or even damaged, resulting in weakened sealing performance

Embodiment 1
[0034] Embodiment 1, in conjunction with attached Figure 1-7 , to further describe the present invention:
[0035] The present invention includes a cover plate 1, a special-shaped sealing ring 2 and a base 3, and the cover plate 1 and the base 3 wrap the special-shaped sealing ring 2 to realize anti-aging sealing; the cover plate 1 includes a cover plate main body 1.1 and a cover plate protrusion 1.2, The cover plate main body 1.1 has a circular structure, and an annular cover plate protrusion 1.2 is provided below the peripheral edge;
[0036] The special-shaped sealing ring 2 is an annular structure, including the hollow part 2.1 of the sealing ring, the two side walls of the sealing ring 2.2, the outer edge 2.3 of the arc-shaped protrusion, and the protrusion 2.4 of the sealing ring. The middle of the wall 2.2 is provided with a sealing ring hollow part 2.1 that cooperates with the cover plate protrusion 1.2, the top of the sealing ring hollow part 2.1 is open, and the bo...
Embodiment 2
[0050] Embodiment 2: Different from Embodiment 1:
[0051] 1. The special-shaped sealing ring is designed as an ellipse as a whole, and the width, height, wall thickness of both sides, and the height of the arc-shaped protrusion can all be adjusted according to the actual needs of the lamp;
[0052] 2. The cover plate is designed as an ellipse corresponding to the sealing ring, and the size of its protrusion can be adjusted according to actual needs;
[0053] 3. The base is designed as an ellipse corresponding to the cover plate, and all dimensions such as the width and height of the groove can be adjusted according to the actual needs of the lamp. The size of the space corresponding to the bottom of the groove and the protrusion of the sealing ring is the same as the protrusion The outlet dimensions are the same.
[0054] The installation process is the same as that in Embodiment 1.
[0055] The sealing ring, the cover plate and the base in this embodiment are all designed ...
Embodiment 3
[0056] Embodiment 3: with reference to attached Figure 8 , different from Embodiment 1, there are multiple groups of arc-shaped protrusions 2.6 on the outside of the two side walls 2.2 of the sealing ring, which can further enhance its sealing effect.

Abstract
The invention relates to an outdoor lamp sealing device with an anti-ageing special-shaped sealing ring. The technical scheme is that the outdoor lamp sealing device comprises a cover plate, the special-shaped sealing ring and a base, wherein the special-shaped sealing ring adopts a circular structure and comprises a sealing ring hollow part, sealing ring two side walls, arc-shaped lug outer edges and sealing ring lugs; the sealing ring hollow part which is matched with a bulge of the cover plate is arranged between the sealing ring two side walls; the top of the sealing ring hollow part is opened and the bottom is closed; the sealing ring lugs are arranged at the bottoms of the sealing ring two side walls; the sections of the sealing ring lugs adopt arc-shaped structures; the arc-shaped lug outer edges are arranged on the two sides of the sealing ring lugs and matched with the base; the base comprises a sealing ring groove, a base main body and an arc-shaped groove; and the arc-shaped groove is arranged at the bottom of the sealing ring groove. Through the special structures of the base and the sealing ring, the sealing ring is completely sealed in the groove and is not in contact with the outside, so that the ageing of the sealing ring is prevented and the sealing property of the sealing ring is ensured.
Description
technical field [0001] The invention relates to a lamp sealing structure, in particular to an outdoor lamp sealing device using an anti-aging special-shaped sealing ring. Background technique [0002] With the improvement of protection level requirements for outdoor lamps, the sealing of lamps has become a difficult problem that lamp manufacturers must overcome. In the current lamp sealing, the sealing ring or sealing strip is generally placed in the groove of the lamp base, and then the base and the cover plate are fixed by bolts or other methods to achieve the sealing effect. This process relies on bolts to fix the base and cover together. The tighter the bolts are, the smaller the gap between the base and the cover is, and the greater the deformation of the sealing ring or sealing strip is. The smaller the gap, when the gap is small enough, it can play a sealing role. The service life of lamps is generally more than five years. As the lamps are used longer, the sealing ...
