Level gauge

The utility model discloses a level gauge, include apron (2), a leak - proof plate (3) connected through bolt (1) according to the preface, amplify transparent plate (4), the 2nd leak - proof plate (5), liquid level board (6) and with bolt (1) complex nut (8), be provided with thermometer (7) on the liquid level board, a leak - proof plate (3) are gone up bolt clearing hole department and are provided with arch (31), enlarged transparent plate (4) are gone up bolt (1) clearing hole department and are provided with cylinder protruding (41), cylinder protruding (41) have breach (42). Adopt level gauge, tighten the bolts (1), a leak - proof plate arch receives the extrusion of amplifying the transparent plate, makes a leak - proof plate push away between apron and bolt head terminal surface almost zero clearance, the oil on the body of bolt is then the breach on protruding flows back to enlarged transparent plate on the surface through the cylinder that amplifies the transparent plate on the run to avoid level gauge oil leak phenomenon.
