Abstract

The invention provides a tool for brushing in a cavity. The tool comprises a brush head assembly, a handle and an angle adjusting piece connected between the brush head assembly and the handle; a micro camera and a lighting device are arranged on the brush head assembly and are used for observing the uniformity of the coating in the cavity. The brush head assembly and the handle are connected through the angle adjusting piece, the position of the brush head is convenient to adjust, paint supplementary brushing is conducted on the limited area of the inner wall of the box body, the micro camerais arranged on the brush head assembly, the coating uniformity condition in the cavity of the box body is convenient to observe, and supplementary brushing is conducted on the area which is not sprayed; by arranging a lighting device on the brush head assembly, the brightness in the cavity can be increased conveniently, the paint spraying situation in an oil tank cavity can be shot conveniently,and therefore it is confirmed that supplementary brushing is conducted on an uneven spraying area or an unsprayed area.

Description

technical field [0001] The invention relates to the technical field of equipment manufacturing, in particular to a tool for brushing in a cavity. Background technique [0002] At present, when manufacturing tanks such as fuel tanks, pipeline spray guns are used to spray the inside of the tanks. However, due to the presence of structures such as oil passages and oil flow chambers on the tanks, there are ribs and other objects inside the cavity, and the pipeline spray guns The spraying angle cannot be effectively controlled, resulting in that the coating sprayed inside the cavity cannot be sprayed evenly, and there are some areas where spraying is missed. Due to the occlusion, it is often difficult for the human eye to observe the area where the spraying is leaking inside the cavity. However, the brushing tools purchased on the market cannot repaint the restricted area inside the cavity, resulting in often unqualified paint inside the cavity. Pipeline spray guns can only be u...
