Embodiment
Below main in conjunction with the drawings and the specific embodiments the bulb switch protection structure of projector is described in further detail.
As shown in Figures 1 and 2, the bulb switch of the projector of execution mode protection structure 10, comprises shell 100, housing 200, switch 300 and flexure strip 400.
On shell 100, offer installing hole 110.
See also Fig. 3, housing 200 is contained in shell 100.Housing 200 is roughly square casing.Concrete, housing 200 is provided with projection 210, and projection 210 is arranged in installing hole 110, is formed with accepting groove 212 on projection 210.On housing 200, be also provided with fixed lobe 220.Further, fixed lobe 220 is roughly cylindrical.On housing 200, be interval with 230, two Elastic buckles 230 of two Elastic buckles that are oppositely arranged and be arranged in installing hole 110.Each Elastic buckle 230 is L shaped.On housing 200, be also provided with positioning convex 240, positioning convex 240 is arranged in installing hole 110, and positioning convex 240 is between two Elastic buckles 230.
Be appreciated that, switch 300 is positioned on housing 200 and is not limited to use positioning convex 240 to be arranged in the mode of Switch main body 310, can also example adopt other, for example, the spacing preiection (not shown) of a bar shaped is set on housing 200, Switch main body 310 connects away from a side and the spacing preiection of metal clips 320, thereby makes Switch main body 310 be limited at the host cavity (figure is mark) that two Elastic buckles 230 and spacing preiection coordinate formation jointly.Be appreciated that switch 300 is fixed on housing 200 and also can use Elastic buckle 230, can also adopt alternate manner, for example, directly use screw (not shown) that Switch main body 310 is fixed on housing 200.
See also Fig. 4 and Fig. 5, flexure strip 400 is strip sheet.Wherein, the material of flexure strip 400 can, for having certain flexible material, be preferably panel beating.Flexure strip 400 is arranged at the outside of shell 100.One end of flexure strip 400 is fixed on housing 200, and the other end and metal clips 320 are away from one end elasticity butt of Switch main body 310, and metal clips 320 is between flexure strip 400 and Switch main body 310, so that flexure strip 400 blocks metal clips 320.Concrete, flexure strip 400 comprises the sheet noumenon 410 of bar shaped and the fixed part 420 being extended to form by one end bending of sheet noumenon 410, fixed part 420 is fixed on housing 200, away from one end of Switch main body 310 and sheet noumenon 410, the one end away from fixed part 420 flexibly supports metal clips 320, and metal clips 320 is between Switch main body 310 and sheet noumenon 410.Further, fixed part 420 is fixed on fixed lobe 220, fixed lobe 220 is provided with spacing projection 222, fixed part 420 offers breach 422 away from the end of one end of sheet noumenon 410, spacing projection 222 is arranged in breach 422, and the sidewall butt of spacing projection 222 and breach 422, thereby to 400 position-limiting actions of flexure strip, be convenient to install.Concrete, on fixed part 420, offer through hole (figure is mark not), on fixed lobe 220, offer screw (figure is mark not), a screw (not shown) is arranged in through hole and screw, and fixed part 420 is fixed on fixed lobe 220.Further, sheet noumenon 410 extends to form kink 430 away from the side edge bending of one end of fixed part 420, switch 300 between kink 430 and housing 200, thereby protect further metal clips 320, prevent that metal clips 320 is touched down from top.Further, sheet noumenon 410 stretches out and forms location division 440 away from the side of one end of fixed part 420, and the edge of a side of location division 440 and the sidewall of housing 200 connects, thereby prevents that flexure strip 400 from excessively pushing metal clips 320.Concrete, kink 430 and location division 440 lay respectively at the relative both sides of sheet noumenon 410.
Further, sheet noumenon 410 extends to form limiting section 450 away from one end bending of fixed part 420, limiting section 450 activities are contained in accepting groove 212, and the bottom of limiting section 450 and accepting groove 212 can butt, thereby the free end of flexure strip 400 is carried out spacing, and prevent that elastic component 400 is pressed excessively simultaneously.Concrete, please again consult Fig. 2, the edge of installing hole 110 is provided with spacing fin 112, spacing fin 112 and the side elasticity butt of limiting section 450 away from the bottom of accepting groove 212, thereby make limiting section 450 between the bottom and spacing fin 112 of accepting groove 212, thereby prevent the free end perk of flexure strip 400, to flexure strip 400, carry out spacing further.
The metal clips 320 of the switch 300 of the bulb switch protection structure 10 of above-mentioned projector is away from one end and the flexure strip 400 elasticity butts of Switch main body 310; and metal clips 320 is between flexure strip 400 and Switch main body 310; so that flexure strip 400 blocks metal clips 320, thereby effectively prevented that the metal clips 320 of switch 300 is touched down.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
