(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

1) the shape is set by adopting the J-shaped ring main body, the distance between the second supply-shaped cambered surface ring and the concave cambered surface ring at the lower part of the J-shaped ring main body is smaller than the distance between the first supply-shaped cambered surface ring and the concave cambered surface ring, the J-shaped ring main body is made of ethylene propylene diene monomer and has elasticity, so that the lamp shell piece is conveniently placed in the concave cambered surface ring for clamping and pressing, the empty groove arranged in the J-shaped ring body provides a compression space, the lamp shell piece is further placed into the concave arc surface ring by assistance, and provides elastic compression for return and increases the stability, the lowest point of the bottom end of the concave cambered ring is lower than the highest point of the top end of the second arc-shaped ring, so as to improve the sealing effect of the bottom end of the attached lamp shell, and the airtight effect on laminating lamp body top is improved to the annular sand grip that sets up of interior anchor ring department to strengthen the steadiness, reached through adopting the beneficial effect of pressing the structure in order to improve the airtight and steadiness of lamp body.

Drawings

Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:

fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic sectional structure of the present invention;

in the figure: j-shaped ring body-1, empty groove-2, first supply arc surface ring-3, inner ring surface-4, concave arc surface ring-5, second supply arc surface ring-6 and annular convex strip-7.

Detailed Description

Referring to fig. 1 and 2, the present invention provides a sealing member for a lamp housing of an automobile headlamp: including J type ring main part 1, dead slot 2, first confession form cambered surface ring 3, interior anchor ring 4, concavity cambered surface ring 5, second confession form cambered surface ring 6 and annular sand grip 7, J type ring main part 1 is inside to be provided with dead slot 2, J type ring main part 1 inboard loops through first confession form cambered surface ring 3 from top to bottom, interior anchor ring 4, concavity cambered surface ring 5 and second confession form cambered surface ring 6 transitional coupling each other, interior anchor ring 4 is provided with annular sand grip 7, and annular sand grip 7 and J type ring main part 1 integrated into one piece.

The lowest point of the bottom end of the concave cambered ring 5 is lower than the highest point of the top end of the second arc-shaped ring 6, and a height difference is formed according to the above, so that the pressing force is increased.
