Specific embodiment
A kind of illuminator sealing structure please refers to Fig. 2 to Fig. 6, including hermetic unit 10, which is installed in
So as to be formed with cavity 40 between light source part 20 and transparent lamp shade 30 between light source part 20 and transparent lamp shade 30, such as the light source portion
It is arranged with light emitting source, therefore the cavity constitutes light source cavity.
The light source part 20 includes shell 21, which has opening, and the 30 sealing-in shell 21 of transparent lamp shade opening should
Hermetic unit 10 is located between shell 21 and transparent lamp shade 30.In specific structure: the shell 21 has ring wall 211, the ring wall 211
Extend outwardly in ring portion 212,212 top surface of ring portion and 211 end face of ring wall and constitutes counterface, 212 periphery of ring portion
Edge is upwardly extended in wall 213；The transparent lamp shade 30 support is located on counterface, which is located at transparent lamp shade 30
Between counterface, which surrounds transparent lamp shade 30 and hermetic unit 10, stays between the wall 213 and transparent lamp shade 30
There is gap.Another that attachment mechanism 50 is arranged, which is installed in one for shell 21, transparent lamp shade 30 and hermetic unit 10
It rises, in specific structure: the attachment mechanism 50 includes C-shaped button 51, and 51 one end contact of C-shaped button is another in 30 top surface of transparent lamp shade
Hold contact in 212 bottom surface of ring portion.
The hermetic unit 10 is made and in a ring of elastic material, it has two to be respectively cooperating with light source part 20 and light transmission lamp
30 mating area 11 is covered, at least one mating area 11 is equipped with interior low outer high inclined surface 111 in two mating area 11.
The hermetic unit 10 can seal water from outside to inside or gas enters realization one-way sealing, but because being equipped with inclined surface 111, therefore in lamp
Have it is in running order under, when lamps and lanterns inner and outer air pressure generates pressure difference (interior be greater than outer), pressure difference, which can act on, to be made to incline on inclined surface
Inclined-plane compresses inwardly, and then drives rectangular section (corresponding rectangle 122) deformation, make this be equipped with the mating area 11 of inclined surface with it is corresponding
It is generated a gap between the part (such as light source part 20 or/and transparent lamp shade 30) of the mating area 11, by the gap to leaking
Pressure, so that lamp interior avoids forming light fitting sealing structure permanent because the hyperbar that work high temperature generates is released
It destroys, to reduce the risk that lamps and lanterns are destroyed by the invasion of external humidification gas and liquid.That is, the hermetic unit 10 is because being equipped with
Inclined surface 111 also constitutes unidirectional pressure relief mechanism, which also may make up check valve.
Among present embodiment: two mating area 11 is designed with above-mentioned inclined surface 111, and, two fitting area
Domain 11 is axially and symmetrically arranged；The hermetic unit 10 includes multiple along the inside and outside linkage section 12 to link together side by side, the linkage section
12 sections include in one low outer high trapezoidal 121 and one be connected to trapezoidal bottom edge rectangle 122, which constitutes above-mentioned
Inclined surface 111, the trapezoidal composition isosceles trapezoid.Two mating areas 11 composition of the hermetic unit 10 has multiple spaced apart
The side inwardly of helical teeth, the helical teeth is above-mentioned inclined surface 111, towards lateral surface vertical plane.The hermetic unit 10 is equipped with rectangle, because
Unilateral bevel edge is trapezoidal to be unlikely to deform, therefore avoids containment portion gas or liquid intrusion, avoids invasion effect good.
The sealing structure of present embodiment is tied as long as replacement hermetic unit can be applicable to existing fitting structure
Structure is simple and easy, can be realized without carrying out biggish adjustment to original technique, has little effect to lamps and lanterns cost.
The above, only the utility model preferred embodiment, therefore, it cannot be limited according to, and the utility model is implemented
It is practical new to should still belong to this for range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual
In the range of type covers.
