The specific embodiment
As shown in Figure 1 and Figure 2, in an embodiment of halogen tungsten lamp fixed structure of the present invention, halogen tungsten lamp 10 has a fixed head 11, the top of fixed head 11 is cloche and filament, the bottom is to be used for the lamp socket that is connected with external electric, and referring to Fig. 6, the edge of fixed head 11 is provided with two spacing breach, one of them is a rectangular indentation 111, and another is a circular arc cutaway 112.
Referring to Fig. 3 and Fig. 4, installing plate 20 is provided with an installing hole 21, and its pore size can pass and have certain free gap to be advisable with the lamp socket of fixed head 11 bottoms that can make halogen tungsten lamp 10; The periphery of installing hole 21 is provided with the screens adaptive with spacing breach, comprise a fixedly screens and an activity screens, in the present embodiment, fixedly screens is by the extended catch 22 of installing plate, being positioned at peace changes the edge in hole 21, when halogen tungsten lamp 10 is packed installing hole 21 into, catch 22 is stuck in the rectangular indentation 111, the opposite side relative with catch 22 of installing hole 21 is provided with an activity screens, this activity screens comprises a multidiameter 30, the shape of multidiameter 30 as shown in Figure 5, comprise the pressing plate 301 that links to each other successively, first shaft part 302, second shaft part 303 and the 3rd shaft part 304, the diameter of pressing plate 301 are greater than the diameter of first shaft part 302, and the diameter of first shaft part 302 is greater than the diameter of second shaft part 303 and the 3rd shaft part 304, have annular slot 305 on the 3rd shaft part 304, be used for mounting spring baffle plate 306; The bar hole 232 that is provided with a through hole 231 and is connected at the opposite side relative of installing hole 21 with through hole 231 with catch 22, bar hole 232 extends radially outwardly along installing hole 21, the diameter of through hole 231 greater than the diameter of first shaft part 302 less than the diameter of pressing plate 301, the width of bar hole 232 greater than the diameter of second shaft part 303 less than the diameter of first shaft part 302, promptly second shaft part 303 can slide in bar hole 232, this activity screens also comprises a spring 307, spring 307 is set on the multidiameter 30, referring to Fig. 2, during assembling, the pressing plate 301 below axis bodies of multidiameter 30 pass through hole 231, overlap upper spring 307 then, the mounting spring baffle plate 306 then, spring 307 1 ends are butted on the installing plate 20, the other end is butted on the spring stop 306, rely on the elastic force of spring 307, multidiameter 30 is installed on the installing plate 20, the diameter of first shaft part 302 and circular arc cutaway 112 are suitable, also promptly the diameter of the diameter of first shaft part 302 and circular arc cutaway 112 is roughly the same, and the two can cooperate preferably.
When halogen tungsten lamp is installed, pressing plate 301 is upwards mentioned, second shaft part 303 is carried to bar hole 232 positions, mobile laterally then multidiameter 30, because the effect of spring 307 and the diameter of first shaft part 302 are greater than the width of bar hole 232, multidiameter 30 can be parked on the bar hole 232, the halogen tungsten lamp 10 of packing into then, catch 22 is stuck in the rectangular indentation 111 of fixed head 11 of halogen tungsten lamp 10, and then mention pressing plate 301, make multidiameter 30 move to through hole 231 to the inside, first shaft part 302 puts down pressing plate 301 over against circular arc cutaway 112 at this moment, under the effect of spring 307, multidiameter 30 moves down, and first shaft part 302 is stuck in the circular arc cutaway 112, and pressing plate 301 is pressed on the fixed head 11 simultaneously.Because the diameter of first shaft part 302 is greater than the width of bar hole 232, described fixed head 11 well is fixed on the installing plate 20 under the effect of catch 22 and multidiameter 30.The process that unloads halogen tungsten lamp is opposite with above-mentioned installation process, repeats no more.
Referring to Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, the edge of installing plate 20 is provided with the fixing hole 24 that has opening, make things convenient for the installation of installing plate 24, have certain vibration-isolating effect in order to make the halogen tungsten lamp fixed structure, card has rubber blanket 25 in fixing hole 24, when this halogen tungsten lamp fixed structure is installed in the light fixture, because the existence of rubber blanket 25 makes this halogen tungsten lamp fixed structure can also tolerate certain vibration, the service life of the light fixture that helps prolonging.
The installing plate of halogen tungsten lamp fixed structure of the present invention can adopt sheet metal component, and the fixedly screens on it can be formed by the direct punching press of installing plate.
In the present embodiment, the spacing breach of fixed head is two, and is symmetrically distributed, a plurality of spacing breach also can be set in actual applications, a plurality of spacing breach can be distributed on the fixed head edge, a plurality of screens of corresponding setting on the installing plate, but comprise a fixedly screens and an activity screens at least.The shape of spacing breach is not limited to the shape among the embodiment, also can be the breach of other shapes.
Fig. 7 shows the structural representation of the taxiway sideline lamp that adopts halogen tungsten lamp fixed structure of the present invention, and 10 be halogen tungsten lamp among the figure, and 20 is the fixing installing plate of halogen tungsten lamp, and 30 is multidiameter.Halogen tungsten lamp fixed structure of the present invention is not limited to be used in this light fixture, also can be applied in other light fixtures that adopt halogen tungsten lamp.
In conjunction with the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
