Abstract

The invention discloses a rapid fluid loading and unloading gun. The rapid fluid loading and unloading gun comprises a chuck which is provided with an axial clamping groove, wherein a sleeve, a first pulling wheel and a second pulling wheel sleeve a fixed shaft at the rear part of the chuck; a plurality of elastic clamping claws which swing in the radial direction are hinged to the periphery of the chuck; a fluid channel is formed in the chuck from the middle to the fixed shaft; an elastic ejector pin is arranged in the fluid channel of the chuck; the second pulling wheel is provided with a spiral long hole matched with a cylindrical pin arranged on the sleeve; the inner side of the upper edge of the second pulling wheel is matched with the outer sides of the rear parts of the elastic clamping claws; the front end face of the first pulling wheel is provided with bulges matched with the inner sides of the rear parts of the elastic clamping claw; the sleeve is provided with a pipe connector which is communicated with the fluid channel on the fixed shaft of the chuck. The rapid fluid loading and unloading gun has a reasonable structure and has the advantages of convenient operation for loading and unloading fluid, high efficiency, good sealing effect, no blockage, rapidness in connection and detachment.

Description

technical field [0001] The invention belongs to a fluid unloading tool, in particular to a fluid quick unloading gun. Background technique [0002] Mechanical devices that adopt gear transmission, such as gearboxes, generally use machine oil for lubrication and cooling. In order to ensure the normal use of the device and prolong the service life, the machine oil must be replaced regularly. When changing the engine oil, you need to unscrew the screw plug of the oil drain hole at the bottom of the tank first, drain the old engine oil in the tank, then tighten the screw plug and then inject new engine oil, such as automobile engine oil pan, rear axle, gearbox, etc. This must be done during and during maintenance. This mode of changing engine oil is cumbersome to operate, and efficient is low, and unclean and hygienic. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and provide a quick-discharging g...
