Abstract
An anticorrosive and explosion-proof operating switch comprises an outer housing. A control circuit is arranged in the outer housing and connected with a control switch; the control switch passes through the outer housing and is exposed outside; the outer housing comprises a casing and a cover body; the casing and the cover body are connected through a bolt; and a gasket ring for sealing is arranged between the casing and the cover body. Because the outer housing comprises the casing and the cover body which are connected through the bolt, the outer housing of the anticorrosive explosion-proof operating switch is convenient to be disassembled for overhauling and maintaining.
Description
(1) technical field
The utility model relates to a kind of anticorrosion explosive operation switch.
(2) background technology
Anticorrosion explosive operation switch is used for explosive dangerous situation.Existing anticorrosion explosive operation switch generally comprises shell, is provided with control circuit in the shell, and control circuit is connected with control switch, and control switch passes described shell and control switch exposes.Its shortcoming that also exists is: in case anticorrosion explosive operation switch breaks down, be difficult to maintenance, just can overhaul, keep in repair after it need being destroyed.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing anticorrosion explosive operation switch, the utility model provides the anticorrosion explosive operation switch of a kind of easy access, maintenance.
The technical scheme in the invention for solving the technical problem is: a kind of anticorrosion explosive operation switch, comprise shell, be provided with control circuit in the described shell, described control circuit is connected with control switch, described control switch passes described shell and described control switch exposes, described shell comprises housing and lid, and described housing is connected by screw with described lid, and is provided with the sealing ring sealing between the two.
Further, be labyrinth seal between described housing and the described lid.
Further, described control switch passes described lid, and the control switch place of passing through of described lid is provided with the glue big envelope, and described glue big envelope is positioned at described shell.
The beneficial effects of the utility model are: 1. because shell comprises housing and lid, and housing is connected by screw with lid, so be convenient to shell taken apart and overhaul and keep in repair.2. owing to be provided with the glue big envelope, so strengthened the intensity that the control switch of shell passes through the place, made the intensity weakness of shell be able to reinforcement at the control switch place of passing through of lid.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of anticorrosion explosive operation switch comprises shell, is provided with control circuit in the described shell.Described shell comprises housing 2 and lid 3, and described housing 2 is connected by screw 4 with described lid 3, and is provided with the sealing ring sealing between the two, is labyrinth seal, good sealing effect between housing 2 and the described lid 3.
Described control circuit is connected with control switch 1, and described control switch 1 passes described lid 3 and described control switch 1 exposes, and the control switch place of passing through of described lid 3 is provided with glue big envelope 5, and described glue big envelope 5 is positioned at described shell.
The utility model is because shell comprises housing 2 and lid 3, and housing 2 is connected by screw 4 with lid 3, so is convenient to shell taken apart and overhauls and keep in repair.In addition, owing to be provided with glue big envelope 5, so strengthened the intensity that the control switch of shell passes through the place, made the intensity weakness of shell be able to reinforcement at the control switch place of passing through of lid 3.
