And finally, screwing down the oil outlet cover.
According to the using rule of the traditional oil tank, when the oil tank filled with gasoline is placed for a long time, the volatile gasoline in the oil tank needs to be discharged periodically, and then a user only needs to unscrew the oil outlet cover and enable the volatile gasoline to flow out of the exhaust hole on the baffle ring; finally, the user needs to tighten the oil outlet cover again.
When the gasoline tank needs to pour out gasoline, a user firstly unscrews the air inlet cap and then unscrews the oil outlet cover; the oil outlet pipe is manually pulled out of the tank body by a user, the hard pipe slides in the sliding hole, and the horn pipe, the sleeve and the sleeve move along with the hard pipe; after the oil outlet pipe is pulled out from the tank body for a certain distance, the flared pipe and the sleeve pipe enter the sliding hole of the threaded boss, the sleeve pipe is blocked by the port of the sliding hole far away from the right hexagonal groove, and the sleeve pipe seals the sliding hole, so that the oil outlet pipe cannot be pulled out from the tank body completely. When the flared tube and the sleeve tube in the oil outlet tube are inserted into the sliding hole of the threaded boss, one end of the swing strip, which is far away from the arc strip, can be sequentially in extrusion contact with the outer tube surfaces of the flared tube and the sleeve tube; along with the process that the sleeve in the oil outlet pipe is inserted into the sliding hole of the threaded boss, the outer pipe surface of the sleeve can gradually break away from the extrusion on one end of the swing strip, which is far away from the arc strip; after the extrusion of the outer tube of sheathed tube one end of keeping away from the arc strip facing the pendulum strip ended, along with going out oil pipe and continuing to remove to the direction of inserting the sliding hole of screw boss, sleeve pipe and telescopic link can be crossed to the one end that the arc strip was kept away from to the pendulum strip, and telescopic urceolus face can continue to maintain the extrusion of the one end of keeping away from the arc strip to the pendulum strip. After the one end of arc strip was kept away from at the pendulum strip received lasting extrusion, the leaf spring was compressed, and the pendulum strip drives the arc strip and breaks away from in the air inlet column, and external atmosphere can enter into the jar body through the arc wall of air inlet column like this. When the oil outlet pipe is pulled out from the tank body for a certain distance to begin to dump gasoline, the blocking cone does not block the corresponding pipe orifice of the hard pipe any more, and the gasoline in the tank body can be dumped out through the oil outlet pipe; in the process of pouring gasoline by using the oil outlet pipe, the space which is less in gasoline in the tank body is that outside air enters the tank body through the arc-shaped groove of the air inlet column, so that the phenomenon that the outside air enters the tank body from the oil outlet pipe can not occur in the process that the oil outlet pipe is filled with gasoline and the gasoline is quickly poured, the turbulent flow phenomenon that the gasoline is poured into the oil outlet pipe due to the fact that the air enters the tank body through the oil outlet pipe is avoided, and further the phenomenon of gasoline leakage caused by the turbulent flow of the gasoline is avoided; in addition, the oil outlet pipe is arranged in the tank body, so that the trouble of finding an oil pipe from other places is eliminated, and the oil tank is convenient to use under various using conditions.
After the oil tank does not dump the gasoline, the user reinserts the oil outlet pipe into the tank body, during the process, the blocking cone is reinserted into the sleeve and the sleeve to re-block the corresponding pipe orifice of the hard pipe, and finally the oil outlet cover is screwed again; one end of the swing strip, which is far away from the arc strip, is not extruded by the sleeve and the sleeve any more, so that under the action of the plate spring, the swing strip drives the arc strip to pass through the arc groove of the air inlet column again, and the sharp corner of the arc strip is exposed outside the air inlet column.
If the oil tank needs short-term multi-frequency gasoline pouring, a user does not need to tighten the air inlet cap again, and therefore the oil tank can be used for pouring gasoline conveniently in a multi-frequency mode. The user does not screw up the cap of admitting air again, and when the petrol was no longer emptyd to the oil tank, the closed angle of arc strip exposed outside the air inlet column, and the closed angle of arc strip can be shunted the dust that the external world dropped to the jar body, and can not make more dust be detained on the arc strip, reaches the purpose that reduces external dust as far as possible and gets into jar body pollution petrol. When the tank does not require a pour of gasoline for a long period of time, the user preferably retightens the inlet cap onto the inlet post.
When the user does not pull out the oil outlet pipe but directly pours the oil tank to pour out the gasoline, the corresponding pipe orifice of the hard pipe is blocked by the blocking cone, so the gasoline cannot flow out of the oil outlet pipe. However, because the exhaust hole on the baffle ring is not shielded, the gasoline can be poured out from the sliding hole of the thread boss and the exhaust hole of the baffle ring; however, the vent holes on the baffle ring are only used for venting, and the hole diameter is not large, so that the speed of pouring gasoline from the vent holes of the baffle ring is slow, and the baffle ring is not suitable for being used as a way for correctly pouring gasoline from a tank. Above, still use the mode that normally pulls out oil outlet pipe and empty petrol better.
The oil outlet module can be produced in a modularized batch mode. When the oil tank needs to be replaced by a new oil outlet module, the screw boss is screwed off from the outlet mounting plate by a user through the hexagonal wrench, and the new oil outlet module can be directly replaced. Because the diameter of the outer circular surface of the sleeve is smaller than the diameter of the inner circular surface of the threaded hole in the outlet mounting plate, when the oil outlet module is replaced, the sleeve on the oil outlet pipe can smoothly come out from the threaded hole of the outlet mounting plate, and therefore the smooth replacement of the oil outlet module is ensured.
The blocking module can be produced in a modularized batch mode. When the oil tank needs to be replaced by a new blocking module, the oil outlet module is ensured to be in an original state at the moment. A user unscrews the threaded disc from the mounting cylinder by rotating the rotating plate, so that the extrusion limit of the threaded disc on the fixed boss is eliminated; then the bolt is unscrewed, and the fixed connection of the fixed boss to the connecting column is released, so that the telescopic rod and the blocking cone can be taken out of the tank body. When a new blocking module is reassembled, the telescopic rod and the blocking cone are firstly inserted into the tank body through the installation cylinder, and during the process, the blocking cone is guided into the sleeve in an inclined mode by the telescopic rod, so that the corresponding pipe opening of the hard pipe is blocked by the blocking cone again under the guiding transition of the cone tip and the outer conical surface of the blocking cone along with the continuous penetration of the telescopic rod. Then, the fixing boss sleeved with the sealing ring is arranged in the mounting cylinder, and the connecting column is fixedly connected with the fixing boss through a bolt; and finally, the threaded disc is installed in the installation cylinder in a threaded fit mode through the rotating plate, and the threaded disc extrudes and limits the fixed boss.
In conclusion, the main beneficial effects of the invention are as follows: when the gasoline in the oil tank is poured, the oil outlet pipe is pulled out, the sleeve pipe seals the sliding hole, and the sleeve is blocked by the port of the sliding hole; during the period of pulling out the oil outlet pipe, the oil outlet pipe extrudes the swing strip to enable the arc strip to be separated from the air inlet column; in-process of dumping gasoline by the oil outlet pipe, the external air enters the tank body through the arc-shaped groove of the air inlet column, the oil outlet pipe is guaranteed to be in the process of quickly dumping gasoline in a state of being filled with gasoline, the phenomenon that the external air enters the tank body from the oil outlet pipe cannot occur, therefore, the turbulent flow phenomenon that the gasoline is dumped by the oil outlet pipe caused by the fact that the air enters the tank body through the oil outlet pipe is avoided, and further the phenomenon that the gasoline leaks due to scattering and flowing of the gasoline is avoided. The oil outlet pipe is arranged in the tank body, so that the trouble of finding an oil pipe from other places is eliminated, and the oil tank is convenient to use under various using conditions. In addition, the oil tank adopts the modularized design, lets go out oil module and stifled module ability batch production, and the oil tank of being convenient for prolongs the life of oil tank greatly through changing the module, avoids the phenomenon that the back oil tank of damage directly discarded, reaches resources are saved's purpose. The invention has simple structure and better use effect.
