Description
Technical field
The utility model relates to a kind of explosion proof and corrosion protection signal lamp, belongs to explosion-proof indicating lamp field of structural design.
Background technology
In existing explosion proof and corrosion protection indicating lamp, the installation portion of Transparent lamp shade is fixed on drain pan by high-frequency welding.The defect that this structure exists is: easily occur rosin joint, sealing is poor, and then causes the explosion-proof performance of product not good, and product is used in hazardous applications, then there is very large potential safety hazard.
Utility model content
To this, the purpose of this utility model is to provide a kind of explosion proof and corrosion protection signal lamp can guaranteeing product explosion-proof performance.
The technical scheme realizing the utility model object is:
A kind of explosion proof and corrosion protection signal lamp, comprises the drain pan and cover plate that form housing, and fixing Transparent lamp shade on the housing and the conducting strip for being electrically connected with outside line; The wiring board be electrically connected with described conducting strip is provided with in described housing, the LED light source be electrically connected with described wiring board is located in described Transparent lamp shade, installation portion is provided with bottom described Transparent lamp shade, described installation portion is fixedly connected with described drain pan by buckle, described installation portion is provided with jack, described conducting strip be electrically connected with described wiring board through described jack, and described installation portion is outside to be provided with and to seal gap between itself and described drain pan and the sealant layer in gap between described conducting strip and described jack.
In technique scheme, described cover plate is fixedly connected with described drain pan by buckle.
In technique scheme, the bottom of described drain pan is provided with slide rail type mounting structure.
The utility model has positive effect: in the utility model, the installation portion of Transparent lamp shade is fixedly connected with described drain pan by buckle, and sealant layer (sealing glue injects Post RDBMS and formed) is to seal the gap between described jack and described conducting strip and the gap between described installation portion outer wall and described drain pan inwall in installation portion outer setting, thus the wiring board of electric spark may be produced and outside explosive environments completely isolated, the quantity of buckle can arrange multiple, described Transparent lamp shade and drain pan reliably can be fixed by adopting this structure, and sealing glue can abundant filling pore, good seal performance, effectively improve the explosion-proof performance of product.

Fig. 1 is the structural representation of signal lamp of the present utility model.
Reference numeral shown in figure is: 1-drain pan; 2-cover plate; 3-Transparent lamp shade; 4-installation portion; 5-conducting strip; 6-LED light source; 7-wiring board; 8-sealant layer.
Detailed description of the invention
Do to illustrate below in conjunction with the concrete structure of Figure of description to explosion proof and corrosion protection signal lamp of the present utility model:
A kind of explosion proof and corrosion protection signal lamp, as shown in Figure 1, it comprises the drain pan 1 and cover plate 2 that form housing (adopt nylon 66 material make), and fixing Transparent lamp shade 3 (adopting PC material to make) on the housing and the conducting strip 5 for being electrically connected with outside line; The wiring board 7 be electrically connected with described conducting strip 5 is provided with in described housing, the LED light source 6 be electrically connected with described wiring board 7 is located in described Transparent lamp shade 3, installation portion 4 is provided with bottom described Transparent lamp shade 3, described installation portion 4 is fixedly connected with described drain pan 1 by buckle, described installation portion 4 is provided with jack, described conducting strip 5 is electrically connected with described wiring board 7 through described jack, and described installation portion 4 outside is provided with and seals gap between itself and described drain pan 1 and the sealant layer 8 (sealing glue inject Post RDBMS and formed) in gap between described conducting strip 5 and described jack.In the present embodiment, the installation portion 4 of described Transparent lamp shade 3 is fixedly connected with described drain pan 1 by buckle structure, and sealant layer is sealing the gap between described jack and described conducting strip 5 and the gap between described installation portion 4 outer wall and described drain pan 1 inwall in installation portion 4 outer setting, thus the wiring board 7 that may produce electric spark is completely isolated with outside explosive environments, the quantity of buckle can arrange multiple, described Transparent lamp shade 3 reliably can be fixed with drain pan 1 by adopting this structure, and sealing glue can abundant filling pore, and good seal performance, effectively improve the explosion-proof performance of product.
In the present embodiment, described cover plate 2 is fixedly connected with described drain pan 1 by buckle, so arranges, and cover plate 2 and described drain pan 1 can be made to assemble more convenient.
For the ease of installing product, the bottom of described drain pan 1 is provided with slide rail type mounting structure, namely adopts slide rail type to be arranged on fixed guide.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
