Embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
Please also refer to Fig. 1 and Fig. 2, it is a kind of light fixture 100 provided by the invention.Described light fixture 100 comprises lamp housing 10 and key device 20.
Lamp housing 10 is provided with resettlement section 12, to accommodate key device 20.
Please also refer to Fig. 3 and Fig. 4, key device 20 is installed in lamp housing 10, for opening and closing light fixture 100.Key device 20 comprises shell 21, button cap 23 and switch module 25.
Shell 21 is roughly hollow cylinder, and it comprises receiving space 210, first step portion 212 and jut 214.First step portion 212 is arranged at the inwall of receiving space 210.Jut 214 is positioned at the top of shell 21.
Button cap 23 is installed on the receiving space 210 of shell 21, and comprises button 230, accepting hole 231, connecting portion 232, contact site 234 and second step portion 236.
In the present embodiment, button cap 23 is quality of rubber materials, has certain elasticity.
Button 230 is positioned at the top of button cap 23, for push switch assembly 25, to control the keying of light fixture 100.After installation, button 230 is protruding is exposed to shell 21, and jut 214 is against the flange 2302 of button 230.In the present embodiment, the top of button 230 is provided with groove 233, thereby button 230 has good elasticity, and button 230 has good pressing or recovery capacity.
Accepting hole 231 is arranged at the inside of button cap 23, for accommodating switch module 25.In the present embodiment, accepting hole 231 extends to top from the bottom of button cap 23, but does not run through button 230.
Connecting portion 232 is between button 230 and contact site 234, and the external diameter of connecting portion 232 is greater than the external diameter of button 230 and is less than the external diameter of contact site 234.During installation, first step portion 212 interference fit of connecting portion 232 and shell 21, thus between shell 20 and button cap 23, form a sealant, to prevent that water or dust from entering key device 20 inside, improved waterproof or the dirt exclusion capabilities of key device 20.
In the present embodiment, the sealant forming between shell 20 and button cap 23, is called as the first resealing of key device 20.
Contact site 234 is positioned at the bottom of button cap 23.Second step portion 236 is arranged at the inwall of accepting hole 231 and between contact site 234 and connecting portion 232.
Switch module 25 is contained in the accepting hole 231 of button cap 23, and comprises circuit board 250 and switch 252, and switch 252 and circuit board 250 are electrically connected.Circuit board 250 is electrically connected with the main circuit board (for diagram) in light fixture 100.During use, button 230 push switches 252, switch 252 touch-control circuit plates 250 are also electrically connected circuit board 250 and the main circuit board in light fixture 100, thereby control the keying of described light fixture 100.
As a further improvement on the present invention, key device 20 also comprises base 27, base 27 and button cap 23 interference fit.
Base 27 comprises protuberance 270 and pedestal 272, and protuberance 270 protrudes from the end face of pedestal 272, and the external diameter of protuberance 270 is less than the external diameter of pedestal 272.The centre of protuberance 270 is provided with accepting groove 271, and after installation, accepting groove 271 is communicated with accepting hole 231, and circuit board 250 is contained in accepting groove 271.
Second step portion 236 interference fit of protuberance 270 and button cap 23, thus a sealant between base 27 and button cap 23, formed, to prevent that water or dust from entering key device 20 inside, further improved waterproof or the dirt exclusion capabilities of key device 20.
In the present embodiment, the sealant forming between base 27 and button cap 23, is called as the second resealing of key device 20.
As shown in Figure 3 and Figure 4, during installation, button cap 23 packs the receiving space 210 of shell 21 into and makes the protruding shell 21 that is exposed to of button cap 23 in the mode of extruding, and make jut 214 against the flange 2302 of button 230, switch module 25 is contained in the accepting hole 231 of button cap 23, the protuberance 270 of base 27 packs the accepting hole 231 of button cap 23 in the mode of extruding, thereby shell 21, button cap 23, switch module 25 and base 27 are assembled into key device 20.At this assembling position, first step portion 212 interference fit of the connecting portion of button cap 23 232 and shell 21, have realized the first resealing of key device 20; The protuberance 270 of base 27 and second step portion 236 interference fit of button cap 23, realized the second resealing of key device 20.
Because key device 20 has the first resealing and the second resealing, thereby water or dust are difficult to enter key device 20 inside, have improved waterproof or the dirt exclusion capabilities of key device 20, and then have improved waterproof or the dirt exclusion capabilities of light fixture 100.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
