Transparent oil plug for oil level observation hole

Abstract

The invention discloses a transparent oil plug for an oil level observation hole and aims to solve the problem of inappropriate oil filling and avoid of burning tanks or causing high temperature failures. According to the technical scheme, the transparent oil plug comprises an oil plug body (1), wherein the oil plug body (1) is mounted on the horizontal oil level observation hole of a transmission housing and in a columnar hollow structure with two opened ends; a screw thread used for connecting the horizontal oil level observation hole of the transmission housing is arranged at the lower end part of the oil plug body (1), and a hexagon flange plane used for wrench operation is arranged at the upper end part of the oil plug body (1); the lower end part of the oil plug body (1) is communicated with the horizontal oil level observation hole of the transmission housing, and a transparent oil cap (2) is arranged at the upper end part of the oil plug body (1) and closely connected with the oil plug body (1). When a transmission adds oil, oil can enter the chamber of the oil plug body (1) and can be observed through the transparent oil cap (2).

Description

technical field [0001] The invention relates to an oil plug, in particular to a transparent oil plug for an oil level observation hole. Background technique [0002] The gearbox can be refueled quantitatively when the whole vehicle is off the assembly line. The oil plugs at home and abroad are basically made of metal materials. The connecting thread is a tapered thread or a straight thread. There are also square structures inside and outside. At present, there is no transparent oil plug that can observe the oil level on the observation oil hole of domestic mechanical gearboxes. During after-sales maintenance, for products such as mechanical gearboxes that are not equipped with oil level sensors, the service station does not have quantitative equipment. The service personnel can only refuel according to experience and feelings, so it is impossible to know whether the amount of oil is added or not, and the user cannot know where the amount of oil should be added. Improper ref...
