Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-4, a kind of bulkhead lamp of replaceable lens, including crust of the device 2,2 upper end of crust of the device are equipped with
End cap 1,1 upper end of upper end cover are fixed with mounting rod 15, and 2 outer end of crust of the device is equipped with circular casing 5, offers ring on circular casing 5
Shape port 4,2 outer end of crust of the device are fixed with annular connection shell 6, and annular connection shell 6 is located at 5 lower section of circular casing, annular connection shell 6
Inner wall slidably connects annular piston plate 11, and 11 upper end of annular piston plate is symmetrically fixed with two connecting rods 8, two connecting rods 8
Upper end sequentially passes through annular connection shell 6 and circular casing 5, and extends to 5 top of circular casing, in two connecting rods 8 and circular casing 5
Endface position is mounted on overhead gage 13, and two connecting rods 8 and 5 lower end surface position of circular casing are mounted on lower baffle plate 9, and annular is even
6 lower end of body contact equidistantly offers several airflow orifices 12, and annular connection 6 lower end of shell is equipped with lens 7.
In the present embodiment, several heat release holes 14 are offered on upper end cover 1,2 outer end of crust of the device and circular casing 5 are close
