Abstract
The utility model relates to an oil gun, composed of a gun body, a switch handle component, a handle protecting component, a main control valve, a gun pipe, a sealing element and a self-sealing device. When a tank to be oiled is filled up, the self-sealing device is pushed by the negative pressure principle so that the oil passage is cut off automatically.
Description
The utility model is about a kind of oilling machine oil gun.
At present, the oilling machine oil gun of domestic production generally by rifle body, gun barrel, control valve, switch handle, protect handle component, filler opening and Sealing and form, when this oil gun refueled, operator will observe the oil level of fuel tank at any time, want manual-lock oil gun switch when fuel tank is filled it up with oil.
The purpose of this utility model is a kind of Oil gun with automatic cutoff device that can close the oil gun switch when fuel tank is filled it up with oil automatically of design.
Oil gun with automatic cutoff device of the present utility model comprises rifle body, switch handle component, protects handle component, gun barrel, master control valve, filler opening, sheath and Sealing, its self-styled function realizes by a self-packer, described self-packer by self-styled film, self-styled core, self-styled bar, from blocking, go up self-styled spring, self-styled spring is formed down.Self-styled film cavity arranged up and down, the self-styled spring of going up is arranged in the upper plenum and between capping, be connected with self-styled core below the self-styled film, self-styled core is in the center hole of self-styled bar.Self-styled bar is that the hollow cylinder of two straight warps of difference is formed, be contained in the circular hole of rifle body, the lower end is connected with an end of switch handle component, self-styled spring down is housed between two cylindrical body joint steps of self-styled bar and the convex shoulder in the rifle body circular hole, in the self-styled bar upper cylinder wall hole of being equipped with more than two from blocking is arranged.The upper plenum of self-styled film is communicated with hole on the tube wall of oil outlet end through gun barrel by vent, and vent is communicated with negative cavity in the gun barrel.
Oil gun with automatic cutoff device of the present utility model beneficial effect compared with prior art be easy to operate, can when fuel tank is filled it up with oil, close oil circuit automatically.
Fig. 1 is the sectional view of the utility model Oil gun with automatic cutoff device.
Now in conjunction with the accompanying drawings the utility model is further described.Oil gun with automatic cutoff device of the present utility model comprises rifle body 2, switch handle component 17, protects handle component 16, gun barrel 1, master control valve 13, filler opening 15, sheath 14 and Sealing, also has the self-packer that when fuel tank is filled it up with oil switch cuts out automatically.Self-packer by self-styled film 6, self-styled core 11, self-styled bar 18, from blocking 8, go up self-styled spring 10, self-styled spring 19 is formed down, self-styled film 6 is by being fitted on the rifle body 2 from capping 7, cavity is arranged down thereon, the space 3 of its upper plenum through forming between vent 5 and gun barrel 1 and rifle body 2 joints is communicated with, space 3 is communicated with hole 22 on the gun barrel 1 oil outlet tube wall by hollow tubular, at the entrance point of gun barrel 1 plastic joint 4 with annular groove is arranged, the outer wall of annular groove evenly leads to space 3 in 2,3,4,5 or 6 holes of distribution, and the aperture is the 1-2 millimeter.
Self-styled film 6 centers are fitted between membrane cover 9 and the film seat 12, membrane cover 9 and between capping 7, adorning and going up self-styled spring 10, and self-styled core 11 is fitted between membrane cover 9 and the film seat 12.Below film seat 12, self-styled bar 18 with self-styled core 11 outside suits, self-styled bar 18 is the hollow cylinder of two straight warps of difference that top is big, the bottom is little, between the outer wall step of two cylindrical body joints and rifle body 2 circular hole bottom convex shoulders, adorning self-styled spring 19, self-styled bar 18 lower ends are connected by the end of pin with switch handle component 17, three holes evenly distribute in the self-styled bar 18 top cylindrical walls, dress is from blocking 8 in the hole, in the hole, be stuck between self-styled core 11 and rifle body 2 circular-hole internal-walls and the convex shoulder from blocking 8, stop self-styled bar 18 to move downward.
Self-styled film 6 is oil resistant rubber and cloth composite material, and thickness is the 0.35-0.45 millimeter.The open circles taper that self-styled core 11 is made for stainless steel material, plastic guides is equipped with in the centre.Self-styled bar 18, membrane cover 9, film seat 12 are plastic materials.
The utility model embodiment's working procedure is: drag switch handle component 17 makes progress, master control valve 13 is opened, and oil refuels to fuel tank through cylindrical outer wall cavity, the gun barrel 1 of master control valve 13, self-styled bar 18 outsides, depresses top flat, withstand in the zigzag fashion groove that protects handle component 16 the oil gun automatic oiling.When fuel tank is filled it up with oil, the hole 22 of gun barrel 1 end is flooded by oil, at this moment, air in the gun barrel 1 in out-of-date self-styled film 6 upper plenums of oil circulation is taken out of by air gap 3, hole 20, negative cavity 21, because the effect of negative pressure, making self-styled film 6 drive self-styled core 11 rises, the self-styled bar 18 switch handle component 17 of ining succession upwards draws high under the effect of following self-styled spring 19, the top flat of switch handle component 17 leaves the zigzag fashion groove and upsprings, owing to lost the support force of top flat, master control valve 13 is depressed switch handle component 17 by push rod under the effect of its spring, closes oil circuit simultaneously.
