Electrically conductive oil box seal structure

Abstract

The utility model discloses a kind of electrically-conductive oil box sealing structures, it is related to oil box sealing technical field, including shell, upper cover and positioning plate, the upper cover is set to the top of shell, the positioning plate is fixedly installed in the bottom of upper cover inboard, the both sides of shell and upper cover are respectively provided with locking structure that is mutually matched and is convenient for opening and overhauling;The utility model has the beneficial effect that: through the setting of shell, upper cover, positioning plate and locking structure, when needing to clean the impurity in shell, only need to rotate threaded rod to make it move through threaded slide plate and locking plate to make locking plate remove the limiting of trapezoidal plate, then manually unscrew hand screw rod, then the limiting fixing of upper cover can be removed, then upper cover can be pulled up to make slide pin slide in sliding slot to make positioning plate draw out from shell, then upper cover can be turned over and opened with slide pin as pivot, then it is convenient to clean the residual impurity in shell and upper cover, convenient and fast to use.
