Embodiment Construction

[0014] A grease gun capable of preventing lubricating oil from flowing back, comprising an oil barrel 1, a gun head 2 respectively placed on the head and bottom of the oil barrel, a rear cover 3, and a handle 4 placed on one side of the oil barrel, and a rubber handle is provided on the handle set.

[0015] The end of the gun head is threadedly connected with an oil pipe 5, and one end of the oil pipe stretches into the inner chamber of the gun head and is threadedly connected with it, and the other end is threadedly connected with a tapered oil nozzle 6. The inner cavity of the gun head is provided with a perforated spacer 7, a spring 8, and a check ball 9. One end of the spring is against the oil pipe port placed in the inner cavity of the gun head, and the check ball is clamped on the other end of the spring and the perforated spacer. Between, the diameter of the non-return ball is larger than the hole diameter of the spacer with holes.

Abstract

The invention discloses a grease gun capable of preventing flowing back of lubricating oil, and belongs to the technical field of oil injecting tools. The grease gun comprises an oil cylinder, a gun head and a back cover respectively positioned at the head part and the bottom of the oil cylinder, and a handle positioned on one side of the oil cylinder. The grease gun is characterized in that the end part of the gun head is in threaded connection with an oil pipe; one end of the oil pipe extends in an inner cavity of the gun head, and is in threaded connection with the same; the other end of the oil pipe is in threaded connection with a conical oil injecting nozzle; a hole separation plate, a spring and a stop round ball are arranged in an inner cavity of the gun head; one end of the spring is butted against a port of the oil pipe positioned in the inner cavity of the gun head; the stop round ball is clamped between the other end of the spring and the hole separation plate; and the diameter of the stop round ball is larger than the aperture of the hole separation plate. The grease gun is reasonable in structure and easy to manufacture, and adds a lubricating oil stop device to solve the oil leaking and returning problems. The grease gun is wide in application range, simple in operation, convenient for carrying and wide in application range, and improves the working efficiency.

Description

technical field [0001] The invention relates to a structure of a grease gun, in particular to a structure of a grease gun capable of preventing lubricating oil from flowing back, and belongs to the technical field of oiling tools. Background technique [0002] A grease gun is a hand tool used to grease mechanical equipment. When it is filled with grease, the source of grease is mainly from the mandrel circulating back and forth in the pump body, and the butter is first sucked into the pump body and then pressurized into the hose. The mandrel works repeatedly in the pump body. Working for a long time will easily cause the lubricating oil in the gun head to flow back, causing oil leakage and blockage. The above problems will affect work efficiency, waste time, bring great inconvenience to work, and sometimes cause waste of resources. Contents of the invention [0003] The object of the present invention is to provide a grease gun capable of preventing lubricating oil from...
