Abstract

The utility model relates to a press stopper with a signal lamp, which comprises a shell, an LED luminescence component positioned in a moving part, a lamp-shade case and an electric switch. The moving part is axially and movably arranged in a zone at one end of the lamp-shade case, the bottom part of the moving part is propped and pressed on the switch triggering piece of the electric switch, the other end of the lamp-shade case is arranged in the shell; the electric switch is arranged in the lamp-shade case and is positioned behind the LED luminescence component along the vertical direction, the electric switch is operated by axially moving the moving part, the lamp-shade case is a hollow column part the top end of which is formed to a non-light tight lamp top cap, one side of which is provided with a communicating glide hole along the axial direction, the press end of the moving part can be movably arranged in the glide hole, the vertex of the press end of the moving part is higher than the most significant end of the top part of the lamp-shade case, and a flame-proof face is formed by a gap between the moving part and the glide hole. The original moving part is free to be used for a push switch of the electric switch, compared with the prior art, the accessories are decreased, and the structure is more compact.

Description

The take a message push-button switch of signal lamp

Technical field

The utility model relates to a kind of explosion-proof signal lamp, relates in particular to a kind of push-button switch of the signal lamp of taking a message.

Background technology

Existing signal lamp is arranged in the housing to this electrically opening and closing mechanism laterally offset by housing, illuminating part, the electrically opening and closing mechanism of band electric-conductor, perhaps is arranged on outside the housing, and can operates by moving axially the light indication piece.

Summary of the invention

The purpose of this utility model is to provide a kind of push-button switch of the signal lamp of taking a message of more compact structure at not enough defective of the prior art.

For achieving the above object, the utility model adopts a kind of push-button switch of the signal lamp of taking a message, comprise a housing, a LED luminescence component that is arranged in movable part, a lampshade cover and an electric switch, movable part axially movably is arranged in the end region of this lampshade cover, the bottom of movable part is pressed on the switch triggering part of electric switch, the other end of lampshade cover is arranged in this housing, electric switch is arranged in this lampshade cover, longitudinally be positioned at after the LED luminescence component, operate electric switch by moving axially movable part, the lampshade cover is the columnar component of a hollow, its top forms the lamp overhead guard of printing opacity, lamp overhead guard one side offers the slip hole of perforation vertically, the press-side of movable part is contained in the slip hole movably, the press-side peak of movable part is higher than the most significant end at lampshade cover top, and the gap of movable part and slip hole forms explosion suppresion surface.

The utility model further is set to movable part by metal struts with compress bar two parts and forms, and metal struts is placed in the slip hole that lampshade overlaps, its lower end with compress the bar clamping and cooperate, the other end that compresses bar is pressed on the switch triggering part of electric switch.

The utility model further is set to push-button switch again and also comprises a cover cap, and cover cap is located at lampshade cover top, the lower surface of cover cap respectively with the top of lampshade cover, the press-side close neighbour of movable part, and the formation activity is by interference fit.

The utility model is independent with original movable part, as the push switch of electric switch, forms a complete lampshade cover simultaneously separately, compares with prior art, and accessory reduces, more compact structure.

Embodiment

As Fig. 1,2, shown in 3, specific embodiment of the utility model 1 is a kind of push-button switch of the signal lamp of taking a message, comprise a housing 1, a LED luminescence component 3 that is arranged in movable part 2, a lampshade cover 4, an electric switch 5 and last, following cover cap (6,7), lampshade cover 4 is the columnar component of a hollow, its upper end forms the lamp overhead guard 41 of printing opacity, the lower end of lampshade cover 4 is arranged in this housing 1, lamp overhead guard 41 1 sides offer the slip hole 42 of perforation vertically, LED luminescence component 3 is located in the hollow chamber 43 in the lampshade cover 4, and electric switch 5 also is arranged in this lampshade cover 41, longitudinally be positioned at after the LED luminescence component 3.Movable part 2 is by metal struts 21 and compress bar 22 two parts and form, metal struts 21 is placed in the slip hole 42 of lampshade cover 4 movably, the gap of metal struts 21 and slip hole 42 forms the explosion suppresion surface b of push-button switch, press-side 211 peaks of metal struts 21 are higher than the most significant end that lampshade overlaps 4 tops 44, the lower end of metal struts 21 cooperates with the upper end clamping that compresses bar 22, and the lower end that compresses bar 22 is pressed on the switch triggering part 51 of electric switch 5.Upper and lower cover cap (6,7) is located at lampshade vertically from top to bottom and overlaps 4 tops, wherein descend the lower surface of cover cap 7 to overlap 4 top 41, press-side 211 close neighbours of movable part 2 with lampshade respectively, and the formation activity can be operated electric switch 5 by moving axially metal struts 21 by interference fit.

Above-mentioned enforcement 1 belongs to plate preceding two normally closed versions.

Shown in Fig. 4,5, the push-button switch of the signal lamp of taking a message of specific embodiment of the utility model 2 adopts plate preceding two normally closed versions, and wherein the structure of movable part 2 is the same with embodiment 1.

The utility model is independent with original movable part 2, separately as the push switch of electric switch 5, forms a complete lampshade cover 41 simultaneously, compares with prior art, and accessory reduces, more compact structure.
