Background technology
Current nozzle is all adopt to refuel directly to fuel tank, larger hole is easily left at the position that gun barrel docks with fuel tank, the easy like this leakage causing oil, also easily cause the leakage of oil gas simultaneously, mainly because time rifle body extend in fuel tank, have larger space between gun barrel and fuel tank oil inlet, so just easily cause the leakage of oil gas.
Summary of the invention
The getter cover mechanism that the purpose of this utility model is to overcome deficiency of the prior art and provides a kind of nozzle, this getter cover can ensure well to seal between oil gun and fuel tank, ensure that and can not leave space between rifle body and fuel tank oil inlet, oil gas is not easy to reveal.
The purpose of this utility model is achieved in that
A kind of getter cover mechanism of nozzle, this getter cover organization establishes is at the gun barrel position of nozzle, described getter cover mechanism comprises getter cover, transfer bar mechanism, described getter cover is connected with transfer bar mechanism, described gun barrel medial surface is provided with a muffler, the rifle body of described gun barrel lateral surface divides and is provided with a return gas channel be communicated with muffler one, and described transfer bar mechanism is arranged in return gas channel, and described return gas channel is communicated with in gun barrel.
Based on the above, described getter cover is an elastic construction, and described getter cover movable set is on gun barrel, and described getter cover one end is fixedly set on rifle body by a larynx hoop, and the other end shrinks slip on gun barrel.
Based on the above, it is globoidal structure that described getter covers on the one end of gun barrel shrinking slip, and this globoidal structure coordinates with fuel tank oil inlet outer fringe seal.
Based on the above, the globoidal structure of described getter cover is intrados structure.
Based on the above, described transfer bar mechanism comprises push rod, push rod spring, described push rod and return gas channel plug-in mounting, described push rod crank motion in return gas channel, one end of described push rod is set with push rod spring, the other end is fixed on a baffle plate by nut, and described baffle plate vertical seal is installed in getter cover, and described baffle plate is set with gun barrel vertical seal again;
The side opening of described return gas channel is provided with the through hole one be communicated with muffler sidewalls orthogonal, the position of described muffler and through hole one vertical connection is closed end, the side of described return gas channel also offers the through hole two be communicated with gun barrel, described through hole two is communicated with gun barrel, and described push rod slides between through hole one and through hole two.
Based on the above, described getter cover is the quality of rubber materials of telescopic folding structure.
The utility model has following advantage:
The utility model has installed getter cover structure and transfer bar mechanism additional on original rifle body, can ensure that oil gas does not leak when oil dropping apparatus refuels, simultaneously all pipe-lines are got through, ensure when filling it up with oil simultaneously, getter cover is drawn in, transfer bar mechanism resets under the effect of getter cover and push rod spring, and realize the blocking to gas distribution channel, actv. prevents the leakage of oil gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model will be further described.
As shown in Figure 1, a kind of getter cover mechanism of nozzle, it is characterized in that: this getter cover organization establishes is at gun barrel 1 position of nozzle, described getter cover mechanism comprises getter cover 2, transfer bar mechanism 3, described getter cover 2 is connected with transfer bar mechanism 3, described gun barrel 1 medial surface is provided with a muffler 4, the rifle body of described gun barrel 1 lateral surface divides and is provided with a return gas channel 1 be communicated with muffler 4, described transfer bar mechanism 3 is arranged in return gas channel 5, and described return gas channel 5 is communicated with in gun barrel 1.By the combination of getter cover mechanism and transfer bar mechanism 3, realize when oil dropping apparatus refuels, the leakage of oil gas can not be produced, and the passage of gas transmission and oil transportation is all smooth and easy, when fuel tank fills it up with oil time, by manually being drawn in by getter cover, at this time promote transfer bar mechanism 3 return, gas distribution channel will be blocked, would not the leakage of oil gas be produced like this.Realize being synchronized with the movement of getter cover and transfer bar mechanism, fundamentally realize not revealing of oil gas.
Based on the above, described getter cover 2 is an elastic construction, and described getter cover 2 movable set is on gun barrel 1, and described getter cover 2 one end is fixedly set on rifle body by a larynx hoop 6, and the other end shrinks slip on gun barrel 1.Described getter cover 2 is the quality of rubber materials of telescopic folding structure.The getter cover 2 of elastic construction mainly in order to refuel fill it up with time, the return movement of getter cover 2 can be realized, thus drive the motion of transfer bar mechanism 3, realize related motion.Getter cover 2 adopts the stretching structure of folded form, can ensure the length of getter cover 2 like this.The getter cover that one end is fixing, can and the oil filling port of fuel tank between form a space sealed, the leakage of oil gas can be prevented like this.
Based on the above, one end that described getter cover 2 shrinks slip on gun barrel 1 is globoidal structure, and this globoidal structure coordinates with fuel tank oil inlet outer fringe seal.The globoidal structure of described getter cover 2 is intrados structure.Getter cover 2 one aspect of intrados structure ensure that the depth seals between getter cover and tank filler opening, on the other hand just in time can spiral-lock at the position of tank filler opening, further achieve the sealing of getter cover 2 and tank filler opening.
Based on the above, described transfer bar mechanism 3 comprises push rod 31, push rod spring 32, described push rod 31 and return gas channel 5 plug-in mounting, described push rod 31 crank motion in return gas channel 5, one end of described push rod 31 is set with push rod spring 13, the other end is fixed on a baffle plate 7 by nut, and described baffle plate 7 vertical seal is installed in getter cover 2, and described baffle plate 7 is set with gun barrel 1 vertical seal again;
The side opening of described return gas channel 5 is provided with the through hole 1 be communicated with muffler 4 sidewalls orthogonal, described muffler 4 is closed end with the position of through hole 1 vertical connection, the side of described return gas channel 5 also offers the through hole 2 502 be communicated with gun barrel 1, described through hole 2 502 is communicated with gun barrel 1, and described push rod 31 slides between through hole 1 and through hole 2 502.Mainly being fixed on getter cover 2 by a baffle plate 7 of transfer bar mechanism, realizes being synchronized with the movement of getter cover 2 and transfer bar mechanism.Baffle plate 7 just in time can be installed on getter cover 2 and fold position, so just in time baffle plate 7 can be installed on this position, be relatively fixed.In addition, undertaken blocking and being communicated with by push rod 31 between through hole 1 and through hole 2 502, and push rod 31 realizes resetting by the contraction of push rod spring 32 and getter cover 2, thus realize blocking of through hole 1 and through hole 2 502, when needs refuel time, stretching getter cover 2 just can realize the outside motion of push rod 31, and push rod spring 32 is stretched to larger position, circulation reciprocal like this, realizes the leakage refueling and prevent oil gas.
