Preferably, it is equipped in self-styled diaphragm upper end without pressure self-packer, this is self-styled by being fixedly mounted on without pressure self-packer The intracorporal piston cylinder of piston and rifle of diaphragm upper end forms, and piston upper chamber is connected to main valve inlet channel.

The utility model has the advantages that being made of in gun barrel Self-enclosing preceding Self-enclosing and rear Self-enclosing, it is equipped in rear Self-enclosing Valve switch closes valve switch when to automobile fuel filler, and valve switch is opened when to motorcycle refueling, and oil gun can be inserted in and rub Motorcycle reservoir port has the characteristics that rapid operation, labor intensity are low, work efficiency is high to motorcycle automatic oiling.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

Oil gun with automatic cutoff device as shown in Figure 1, including gun body 1, gun barrel 2, handle 3, main valve 4, self-packer and check valve 5, it is main Valve 4 is mounted in the asphalt channel in gun body 1, and mandril lower end top is mounted in 3 middle part of handle, and self-packer is by self-styled diaphragm 6, control Bar 7 processed, self-styled bar 8 form, and self-styled 8 lower end of bar and 3 front end of handle join, upper end outer circle radial direction step and 1 inner hole step of gun body Between self-styled spring 9 is installed, the sealing of 7 upper end of control-rod is fixed at self-styled 6 center of diaphragm, and lower end is inserted into self-styled 8 center of bar In hole, self-styled 8 upper end of bar is equipped with several radial holes, is formed with shrinkage pool, Mei Gejing on 1 inner hole wall of gun body on the outside of the radial hole The steel ball 10 that diameter is greater than the radial direction bore dia is installed into hole, self-styled 6 epicoele of diaphragm is connected to the Self-enclosing of gun barrel front end, adds Pull-up handle 3 when oily is opened main valve 4 by mandril in the middle part of handle 3, and 3 front end of handle moves down the pulling of self-styled bar 8, steel ball 10 It is embedded between the radial hole of self-styled bar 8 and the shrinkage pool of gun body 1, to vehicle automatic oiling, when oil level seals Self-enclosing in fuel tank, Self-styled 6 epicoele of diaphragm generates negative pressure and pulls up control-rod 7, and steel ball 10 rolls out the inner hole to self-styled bar 8 from the shrinkage pool of gun body 1 In, self-styled bar 8 moves up under the effect of self-styled spring 9, and handle 3 is pulled to close main valve 4, terminates to refuel；Self-enclosing is by preceding self-styled Hole 11 and rear pore self-sealing 12 form, and are equipped with valve switch 14 in rear pore self-sealing 12, close valve switch 14 when to automobile fuel filler It closes, refueling position is controlled by preceding Self-enclosing 11, valve switch 14 is opened when to motorcycle refueling, oiling position is controlled by rear Self-enclosing It sets, realizes to motorcycle automatic oiling, it is easy to lubricate, laborsaving.

It is equipped in self-styled 6 upper end of diaphragm without pressure self-packer, this is without pressure self-packer by being fixedly mounted on self-styled diaphragm 6 The piston at end and the piston cylinder in gun body 1 form, and piston upper chamber 13 is connected to 4 intake channel of main valve, when 4 import of main valve is without oil pressure When, piston is moved up in the promotion of its lower end spring, is pulled self-styled bar 8 to move up and is closed main valve 4, is realized without pressure self-sealing function.
