Abstract

The invention discloses a fluid leaking gun, which comprises a tubular central rod, an elastic thimble movable in the front end of the central rod and capable of axial movement, a connecting cover fixed on the outer wall of the front part of the central rod, and a connecting cover movable in the middle of the central rod. The outer wall and the rotatable unlocking wheel located behind the connecting cover; a card slot is formed between the connecting cover and the central rod, and the inner wall of the connecting cover is provided with an elastic lock bolt extending into the card slot for radial movement; the unlocking A shift block is arranged on the wheel to radially cooperate with the elastic lock bolt to realize the radial movement of the elastic lock bolt. The present invention can be matched with the oil discharge device of the fuel tank, and can be quickly connected and disassembled with the oil discharge device during use, and is convenient to use; it can realize complete sealing, prevent oil leakage, and realize fast fluid discharge.

Description

technical field [0001] The invention belongs to leaking fluid equipment, in particular to a fluid leaking gun. Background technique [0002] Gearboxes are widely used for speed change in vehicles, ships, and engineering equipment. Oil replacement is an important part of gearbox repair and maintenance. In order to replace the engine oil, the gearbox adopts the structure of setting an oil drain screw on the oil pan. When changing the oil, unscrew the oil drain screw first, drain the waste oil directly from the oil drain hole, and then add new oil from the filler port. Since the oil drain screw must be unscrewed every time the oil is changed, and then screwed on after the oil is drained, the thread of the oil drain hole of the oil pan is easily damaged if the oil is changed too many times or carelessly, resulting in damage to the oil pan, leaking, light If the oil pan needs to be replaced, the engine will be scrapped if it is heavy. The traditional gear box oil drain screw s...
