Detailed Description

Referring to fig. 1 and 2, the portable fuel filling apparatus includes a fuel tank 1, a fuel filling hose 3, and an electric fuel filling gun. The electric oil gun comprises a power device, an oil cylinder 16, a piston 13, an oil nozzle and a handle 14. The handle 14 is attached to the outside of the barrel 16 for carrying and use of the electric fuel gun. The power device is composed of a motor 8, a screw rod 9, a screw rod nut 10, a baffle 11 and a piston rod 12. The motor 8 is a speed reducing motor and is arranged at the rear end of the oil cylinder 16. The screw rod 9, the screw nut 10, the baffle plate 11, the piston rod 12 and the piston 13 are positioned in the oil cylinder 16. And an output shaft of the motor 8 is coaxially and fixedly connected with the screw rod 9. And a screw nut 10 is sleeved and connected on the screw rod 9. The front end of the screw nut 10 is fixedly connected with the rear end of the piston rod 12. The baffle 11 is positioned at the front end of the screw rod 9 and is fixedly connected on the inner wall of the oil cylinder 16. The baffle 11 is provided with a through hole which penetrates through the baffle 11 from front to back, and the piston rod 12 penetrates through the through hole. The front end of the piston rod 12 is fixedly connected with a piston 13. The piston 13 divides the inner cavity of the oil cylinder 16 into a front part and a rear part, and lubricating oil is contained in the front cavity. The front end of the oil cylinder 16 is provided with an oil outlet nozzle, a second one-way oil injection valve 7 is arranged in the oil outlet nozzle, and the second one-way oil injection valve 7 can be opened outwards. An oil inlet pipe is arranged at the front side part of the oil cylinder 16, and the oil inlet pipe is provided with a first one-way oil injection valve 6 which can be opened inwards. The oil storage tank 1 is a cylindrical tank body or a square tank body, and the front side of the oil storage tank is provided with a strap 2 so as to facilitate the carrying of the oil storage tank 1. The upper end of the oil storage tank 1 is provided with a scavenging valve 15 or an air inlet, and the lower end of the oil storage tank 1 is provided with an oil outlet pipe 5. The oil outlet pipe 5 is communicated with an oil pipe of the oil cylinder 16 through the oil filling hose 3, and the valve 4 is arranged on the oil outlet pipe 5. After the structure is adopted, when the motor 8 drives the screw rod 9 to rotate forwards (reversely), the piston rod 12 fixedly connected with the screw nut 10 is limited by the baffle 11 and can not rotate, and the screw nut 10 can not rotate, so that the non-rotating screw nut 10 and the rotating screw rod 9 can rotate relatively, and the screw nut 10 is pushed to move forwards; the forward screw nut 10 pushes the piston 13 to move forward, so that the lubricating oil is extruded forward; since the second one-way oil injection valve 7 can only be opened outward and the first one-way oil injection valve 6 can only be opened inward, the extruded lubricating oil pushes the second one-way oil injection valve 7 forward to flow out from the oil outlet nozzle for oil injection. When oiling is needed after oiling is finished, the motor 8 is controlled to rotate reversely (rotate forwards), and the non-rotating lead screw nut 10 and the rotating lead screw 9 rotate relatively, so that the lead screw nut 10 is pushed to move backwards; the backward-moving screw nut 10 pushes the piston 13 to move backward, and negative pressure is formed in the front cavity of the oil cylinder 16; because the first one-way oil filling valve 6 can only be opened inwards and the second one-way oil filling valve 7 can only be opened outwards, the first one-way oil filling valve 6 is opened inwards under the action of negative pressure, so that lubricating oil in the oil cylinder 16 is pumped into the oil cylinder 16 through the oil filling hose 3, and the next oil filling operation is facilitated.

For a clearer description of the beneficial effects of the present invention, the following description is made in conjunction with the practical operation of the present invention in the using process.

Referring to fig. 1 and 2, the portable oil filling device for lubricating comprises the following steps: in the first step, a worker communicates the electric fueling gun with the oil storage tank 1 through the fueling hose 3 while unscrewing the valve 4. In the second step, the worker takes up the oil tank 1 by the harness 2 and holds the grip 14 to pick up the electric fuel gun. And thirdly, before the mechanical equipment is reached and the oil outlet nozzle is aligned to the position needing lubricating, the motor 8 is manually opened to start to fill lubricating oil. In the lubricating oil filling process, the electric oil gun is small in size, so that the electric oil gun can be better adapted to mechanical equipment in a narrow space or narrow lubrication work at a position where the mechanical equipment needs to be lubricated; in addition, in the process of filling lubricating oil, as long as the driving piston 13 moves backwards, the lubricating oil in the oil storage tank 1 can be continuously pumped into an oil storage chamber of the electric oil filling gun to perform the lubricating maintenance work of mechanical equipment.
