Detailed Description
The embodiments of the present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-4, an explosion-proof lamp includes a lamp housing 1 and a lamp cover 2, wherein the lamp housing 1 is substantially basin-shaped, and has an opening at an upper end thereof, a driving power supply and a light source 4 are installed inside the lamp housing, and the light source 4 is installed at the opening at the upper end; the lamp body 1 upper end is formed with the encapsulating structure, lamp shade 2 bonds in lamp body 1 upper end through the encapsulating is sealed, lamp shade 2 covers light source 4.
As shown in fig. 2-3, an inner annular wall 11 and an outer annular wall 12 are formed concentrically on the upper end surface of the lamp housing 1, the light source 4 is disposed inside the inner annular wall 11, an annular glue-pouring groove 13 is formed between the inner annular wall 11 and the outer annular wall 12, and the height of the inner annular wall 11 is higher than that of the outer annular wall 12; the lampshade 2 comprises an opening end 21, the opening end 21 is correspondingly arranged in the annular glue pouring groove 13, and a certain glue pouring gap is formed between the opening end 21 and the upper end faces of the inner annular wall 11, the outer annular wall 12 and the lamp shell 1; the annular glue pouring groove 13 is filled with the sealant 3, and the sealant 3 fills the glue pouring gap, so that the opening end 21 of the lampshade is hermetically bonded with the inner annular wall 11, the outer annular wall 12 and the end face of the lamp housing 1 through the sealant 3.
By adopting the scheme, glue is directly filled into the annular glue filling groove, the lampshade and the lamp housing are hermetically bonded through the sealant, the operation is convenient, the connection is reliable, the structure is simple, and the cost is low. In addition, form annular encapsulating groove, the height that highly is higher than outer rampart of its interior rampart not only makes the encapsulating in-process, effectively avoids glue to spill over from the interior rampart, and the air current upwards emits moreover, reduces the bubble to further guarantee the encapsulating quality.
As shown in fig. 3, an annular boss 14 is disposed on an end surface between the inner annular wall 11 and the outer annular wall 12, the annular boss 14 is preferably disposed on an outer side wall of the inner annular wall 11, and an outer diameter of the annular boss 14 is smaller than an outer diameter of an open end 21 of the lamp housing 2, after the open end 21 of the lamp housing 2 is placed in the annular glue filling groove 13, the open end 21 is supported by the annular boss 14, so that a certain gap exists between the open end 21 and an upper end surface of the lamp housing 1, when glue is filled into the annular glue filling groove 13, the glue enters the gap between the gap, and lifts the lamp housing 2, so that the glue can better enter the glue filling gap between the open end 21 and the inner annular wall 11.
Certainly, in order to realize more stable cooperation between lamp shade and the lamp body, the inner wall of outer rampart 12 corresponds with the outer wall of open end 12 and is formed with the spacing step of circumference interval arrangement, and it is spacing to realize the axial of lamp shade and lamp body through spacing step, when toward annular encapsulating groove 13 in the encapsulating, glue will lift the lamp shade until spacing step contact spacing, overall structure is reliable and stable, moreover through its this limit structure, further reduce manual operation, it is more convenient to operate.
Furthermore, the upper ends of the inner ring wall 11 and the outer ring wall 12 are chamfered or rounded, so that the open end 21 of the lampshade 2 can be more easily clamped into the annular glue pouring groove 13.
