Description

Technical Field

[0001] The utility model relates to the technical field of fuel dispensers, in particular to a semi-automatic pressurized fuel dispenser. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It has the advantages of reducing wear, extending equipment life, cooling, reducing equipment damage caused by corrosion, lubrication and sealing. Lubricating oil is one of the keys to ensure the long-term normal operation of equipment. Therefore, during the equipment maintenance process, many equipment need to replace lubricating grease to ensure the protective effect of lubricating oil on the equipment. At present, a lubricating oil dispenser is required when injecting lubricating oil into the equipment.

[0003] However, the equipment at the maintenance site is located in various positions, with different heights and different designs of the refueling ports. It is difficult to refuel most equipment with oil cans: some equipment has small refueling ports, and some are on the side, which leads to slow refueling and unnecessary leakage of lubricating grease, polluting the ground and wasting resources. In addition, the existing refueling machines cannot select the appropriate oil pump starting method according to the amount of oil, so for manual refueling machines, it is time-consuming and laborious to inject a large amount of oil, and for electric refueling machines, it will cause a waste of electricity when injecting a small amount of oil. The existing refueling machines cannot flexibly switch the driving method of the oil pump.

[0004] Therefore, there is an urgent need to provide a semi-automatic pressurized fuel dispenser that can achieve flexible conversion of the fuel pump drive mode compared to the prior art. Utility Model Content

The axis of the handle 12 is arranged parallel to the axis of the turntable 11. The handle 12 is arranged close to the outer peripheral surface of the turntable 11. The handle 12 is manually rotated to drive the turntable 11 to rotate, so that the rotating shaft 33 of the oil pump 3 rotates with the rotation of the transmission rod 6 to drive the oil pump 3.

[0034] When the oil injection amount is greater than or equal to the first set value and less than or equal to the second set value, the driving component is an electric wrench, which is clamped on the end of the transmission rod 6 away from the box body 1, and the electric wrench is started to make the rotating shaft 33 of the oil pump 3 rotate with the rotation of the transmission rod 6, thereby driving the oil pump 3.
