Description
Technical field
It the utility model is related to field of explosion, more particularly to a kind of double-deck shield explosion-proof signal lamp.
Background technology
Usually need that explosion-proof signal lamp is installed in flame proof cavity, the structure of existing explosion-proof signal lamp is in lamp bead overcoat one
Individual lampshade composition, this explosion-proof signal lamp with the increase of usage time, lampshade can gradual aging, crack or even broken can be produced
Split, so may result in lamp bead and be fully exposed in flame proof cavity, it is extremely dangerous.
Utility model content
The utility model is in view of the above-mentioned problems, propose a kind of double-deck shield explosion-proof signal lamp.
The technical scheme that the utility model is taken is as follows：
A kind of double-deck shield explosion-proof signal lamp, including lamp bead, housing, lamp body and lampshade, the enclosure interior is hollow, described
Lampshade is installed on above housing, and the lamp body is installed on below housing, and the lamp bead is installed on lamp socket by wiring board, also wrapped
Translucent cover is included, the translucent cover is arranged on above lamp body, and lamp bead and wiring board are isolated in one by translucent cover jointly with lamp body
In closed space.
Because lamp bead has the duplicate protection of lampshade and translucent cover so that lamp bead is effectively protected, when positioned at outer
During the lampshade rupture of side, lamp bead will not be directly exposed in flame proof cavity, will not cause peril.
Optionally, in addition to copper pin, the copper pin are installed on lamp body, and copper pin is connected by wire with wiring board.
Copper pin is used to connect external power cord and back panel wiring plate, ensure that supply of electric power.
Optionally, filling with sealant layer in the space formed between the lamp body, translucent cover and housing three.
The fluid sealant can not deform upon in low temperature and high-temperature, sealant layer first to lamp body, translucent cover and
Housing three serves the fixed effect with support, second plays sealing function.
Optionally, in addition to dust cap and screw, the dust cap are installed on below lamp body, and the screw is arranged on lamp body
Lower section, and turned on copper pin；And screw is located in dust cap, dust cap is provided with the projection of limitation screw stroke.
The effect of dust cap is to prevent external dust from entering, and whole double-deck shield explosion-proof signal lamp is played a protective role,
Because outer lead needs to be conducted with copper pin by screw, therefore need first to when installing double-layer explosion-proof signal lamp
Screw is unscrewed to be tightened again, and raised restriction effect effectively can prevent screw from being dropped during unscrewing.
Optionally, it is characterised in that periphery is along being above provided with screw thread on the housing.
Double-deck shield explosion-proof signal lamp is by being threadably mounted on flame proof cavity.
Optionally, interface is provided with sealing ring between the housing and lampshade.
The effect of sealing ring is the space between sealed lamp shade and housing.
Optionally, annular groove is provided with the housing exterior walls, seal washer is nested with annular groove.
After double-deck shield explosion-proof signal lamp is arranged on flame proof cavity, first the effect of seal washer is sealing explosion-proof chamber
Fixing clearance between body and double-deck shield explosion-proof signal lamp, a support second is played to whole double-deck shield explosion-proof signal lamp
Effect.
The beneficial effects of the utility model are：Lamp bead has double shielding, safe, installation facility.
Brief description of the drawings：
Fig. 1 is double-deck shield explosion-proof signal lamp structure schematic diagram.
Each reference is in figure：1st, lampshade, 2, sealing ring, 3, seal washer, 4, screw thread, 5, translucent cover, 6, terminal plate,
7th, copper pin, 8, lamp body, 9, dust cap, 901, raised, 10, lamp bead, 11, housing, 12, sealant layer, 13, screw.
Embodiment：
With reference to each accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of double-deck shield explosion-proof signal lamp, including lamp bead 10, housing 11, lamp body 8 and lampshade 1, shell
The inner hollow of body 11, lampshade 1 are installed on the top of housing 11, and lamp body 8 is installed on the lower section of housing 11, and lamp bead 10 is installed by wiring board
In on lamp socket, in addition to translucent cover 5, translucent cover 5 is arranged on the top of lamp body 8, and translucent cover 5 and lamp body 8 jointly by lamp bead 10 with
Wiring board is isolated in a closed space.
Because lamp bead 10 has the duplicate protection of lampshade 1 and translucent cover 5 so that lamp bead 10 is effectively protected, when
When lampshade 1 positioned at outside ruptures, lamp bead 10 will not be directly exposed in flame proof cavity, will not cause peril.
As shown in Figure 1, in addition to copper pin 7, copper pin 7 are installed on 8 on lamp body 8, and copper pin 7 passes through wire and wiring board phase
Connect.
Copper pin 7 is used to connect external power cord and back panel wiring plate 6, ensure that supply of electric power.
As shown in Figure 1, filling with sealant layer in the space formed between lamp body 8, translucent cover 5 and the three of housing 11
12。
The fluid sealant can not deform upon in low temperature and high-temperature, and sealant layer 12 is first to lamp body 8, translucent cover
5 and the three of housing 11 serve the fixed effect with support, second play sealing function.
As shown in Figure 1, in addition to dust cap 9 and screw 13, dust cap 9 are installed on the lower section of lamp body 8, and the screw 13 is pacified
Mounted in the lower section of lamp body 8, and turned on copper pin 7；And screw 13 is located in dust cap 9, dust cap 9 is provided with the limitation stroke of screw 13
Projection 901.
The effect of dust cap 9 is to prevent external dust from entering, and whole double-deck shield explosion-proof signal lamp is played a protective role,
Because outer lead needs to be conducted with copper pin by screw 13, therefore elder generation is needed when installing double-layer explosion-proof signal lamp
Screw 13 is unscrewed and tightened again, raised restriction effect can effectively prevent screw 13 from being dropped during unscrewing.
