In line portion;
Further, the second sealing ring is nested on the bottom face of lamp housing, the second sealing ring is pressed against the top of lampshade
On face.
Further, the centre at the top of the lamp housing is bolted with lamp cap, and the bottom sleeve of lamp cap is in minor diameter spiral shell
It connects in hole section, the bottom of lamp cap and minor diameter are spirally connected between the top surface of hole section and are clamped with third sealing ring, and lamp mainboard passes through connection
Line is electrically connected with lamp cap.
Further, the diameter of the connecting thread portion of the lamp housing is less than the diameter of the bottom outside wall of lamp housing,
There are multiple annular thermal troughs on the bottom outside wall of lamp housing.
Further, the 4th sealing ring is nested on the lateral wall of the lamp housing of the lower section of the connecting thread portion.
Protrusion effect of the invention is:
Compared with prior art, it has waterproof performance, meanwhile, guarantee that heat dissipation effect, all parts can be dismantled, side
Just maintenance maintenance is replaced.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment:
Embodiment, as shown in Figure 1, a kind of Waterproof LED lamp cap device, including lamp housing 10, the top of the lamp housing 10
There is connecting thread portion 11 on lateral wall, there is stairstepping connecting groove 12 in the middle part of the bottom surface of lamp housing 10, stairstepping connection is recessed
The top of slot 12 is that minor diameter is spirally connected hole section 121, and the lower part of stairstepping connecting groove 12 is major diameter hole section 122, inside connection
Ring 13 is screwed onto minor diameter and is spirally connected in hole section 121, has convex annular looping 131, radiating block on the bottom face of internal connection ring 13
14 sleeves are nested with lamp mainboard 1 in the middle part of the bottom surface of radiating block 14, the bottom surface of lamp mainboard 1 is fixed with more in major diameter hole section 122
A LED lamp 2, lampshade 20 are screwed on the bottom face of lamp housing 10, and the middle part of lampshade 20 has through-hole 21, and Anti-explosive glass 22 is solid
It is scheduled in lampshade 20 and is covered through-hole 21, there is protruding ring 23 in the middle part of the top surface of lampshade 20,23 sleeve of protruding ring is in large diameter hole
In section 121 and it is pressed against the bottom face and lamp mainboard 1 of radiating block 14, the top surface of radiating block 14 has annular groove 141, convex annular
Looping 131 is nested in annular groove 141, and the bottom face of internal connection ring 13 is pressed against on the top surface of radiating block 14.
Further, the bottom inside wall of the through-hole 21 has positioning annular groove 211, the inside top of through-hole 21
Wall is diminishing conical inner side wall from bottom to top, has on the side wall of Anti-explosive glass 22 and radially extends circle 221, radially extends
Circle 221 is nested in positioning annular groove 211, and annular cover plate 222 is bolted to connection on the bottom face of lampshade 20, ring
Shape cover board 222, which is pressed against, to be radially extended on circle 221.
