The extension for being used for installing attachment screw is formed, the edge of radiating shell is corresponding with the extension, wherein, connect spiral shell
The end of thread of nail is located at radiator grille side, and the head of screw of attachment screw is located at radiating shell side；The attachment screw will above
Cover is connected fixed (without being socketed seal washer on attachment screw) with radiating shell；Correspond in the edge of radiating shell
The inside region of attachment screw, is provided with annular groove, the annular sealing strip of filling flexible in the annular groove, the rear portion of radiator grille
Annular groove is provided with annular protrusion so that the annular protrusion contacts and extrudes annular sealing strip during attachment screw tightening
Annulus central area reach sealing effect.
Based on above scheme, the present invention has also further made following important optimization：
The width ratio that the width of above-mentioned annular protrusion accounts for annular groove is 1/4~1/3.
The thickness of above-mentioned annular sealing strip is less than the depth of annular groove.
Rear portion arc-shaped transition of the above-mentioned extension based on radiator grille.
The width of above-mentioned annular groove is 3.5-6mm, and the width of annular protrusion is 1.5-2mm.
Above-mentioned extension corresponds to the exterior lateral area of attachment screw straight down so that when radiator grille is fastened with radiating shell
The screw parts of attachment screw can be covered.
For lampshade sealing installation structure：Radiator grille specifically includes housing, reflector, lampshade and annular rubber ring, housing
Middle part is provided with mounting hole position, and the cross section of annular rubber ring is U-shaped, and U-shaped opening is towards mounting hole position axle center；The reflector
Edge be bonded with the edge of lampshade, and be embedded in jointly in annular rubber ring U-type groove, annular rubber ring is limited in the installation of housing
Kong Wei, and connected in mounting hole position periphery by trip bolt and realize being further fixed to annular rubber ring.
The table top that above-mentioned housing sets a circle to sink at mounting hole position is used to place the annular rubber ring；In housing
Lateral surface, trip bolt and fastening structure part, fastening structure part extend into annular rubber ring described in the periphery configuration of mounting hole position
The part on surface has tip protuberance so that the tip protuberance produces extruding to annular rubber ring after installation trip bolt
Effect.
Fastening structure part is annular structural part, has the same center of circle with mounting hole position, sealing and fixed effect are more preferably.When
So, 3-6 discrete fastening points can also be evenly arranged in mounting hole position periphery and carry out tightening.
It is raised that at least one circle can be disposed with the table top that an above-mentioned circle sinks, for being produced upwards to annular rubber ring from below
Raw squeezing action.
The tip protuberance at two is preferably radially sequentially arranged, sealing and fixed effect are more preferably.
The invention has the advantages that：
Sealed connection for LED lamp radiator grille and radiating shell, attachment screw are displaced on the outside of seal groove so that
Screw need not remake waterproof sealing design, and waterproof sealing effect is more preferable, it also avoid the damage to sealant rubber ring.
The installation of lampshade causes reflector and lampshade to be mounted as an entirety using U-shaped annular rubber ring, pacifies
Dress is easy, reliable, and sealing effect is good, and easy to safeguard.
The fixation of reflector and lampshade installation avoids device damage without rigid contact.
