Abstract

The utility model relates to a fast-open door type mine explosion-proof switch with a gear structure, comprising a shell, an explosion separating cavity and a door panel; a turning ring of a door lifting mechanism is installed in a base of the door lifting mechanism after being welded with a handle of the door panel, one side of the door lifting mechanism is sheathed with a door leaf supporting shaft; the door leaf supporting shaft, together with a lower door leaf, is mounted on the door panel, the upper end and the lower end of the door leaf supporting shaft are arranged on the shell through door spindle jacking blocks, and the junction surfaces between the turning ring of the door lifting mechanism and the door leaf supporting shaft all adopt the gear structure. The explosion-proof switch with a door type is convenient and reliable and can prolong the service life of the switch and improve production efficiency simultaneously.

Description

Gear structure fast opening type mine explosion-proof switch

Technical field

The utility model relates to a kind of mine explosion-proof switch.

Technical background

Mine explosion-proof switch is made of housing, door and explosion-proof chamber, between door and the housing by handle as opening the door mode.Traditional opening structure has adopted cam structure, in use lean on realizing of door fully from gravity, it is time-consuming relatively to require great effort in the switch door process of switch, and in use require door and body clearance ratio of precision higher, if switch is above certain time limit service time, it is not in place that this mode of opening the door causes this door to cooperate with housing easily, influences the security performance of switch.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of gear structure fast opening type mine explosion-proof switch is provided, and the mode of opening the door is convenient and reliable, has improved the useful life and the production efficiency of switch simultaneously.

For achieving the above object, the solution that this practicality is taked is: a kind of gear structure fast opening type mine explosion-proof switch, it comprises housing, explosion-proof chamber, door closure, rise a door mechanism turn-take with the welding of door closure handle after be installed in and rise in the door mechanism seat, a side that rises door mechanism seat is with a door leaf back shaft and is installed on the door closure in the lump with following door leaf, the door leaf back shaft is installed on the housing by the door-hinge jacking block up and down, rises the faying face that door mechanism turn-takes with the door leaf back shaft and all adopts gear structure.

The power that the utility model relies on gear structure to walk about up and down drives the lifting of door, realizes opening the door easily and reliably.Simultaneously, the useful life and the production efficiency of switch have been improved.
