Abstract

The invention relates to a manual lubricating oil supply device, in particular to a grease gun. The grease gun comprises an oil storage barrel and an end cover. The oil storage barrel is made of transparent materials. A piston, a piston rod and a spring are arranged inside the oil storage barrel. The piston rod axially is arranged inside the oil storage barrel in a penetrating mode. The spring is arranged outside the piston rod in a sleeved mode. The piston rod is connected with the piston. The oil storage barrel is matched with the end cover in a threaded connection mode. The end cover is a plastic part. A lever type oil outlet mechanism and an oil outlet pipe are arranged on the end cover. A grease packaging bottle is arranged inside the oil storage barrel and comprises a bottle body and a bottle cover. The bottle body comprises a main bottle body and a bottle bottom. The bottle body is a flexible body. An elastic spiral hard part is arranged in the axial direction of the main bottle body, wherein the hardness of the spiral hard part is larger than that of other parts of the main bottle body. The spiral hard part is the spring. The main bottle body is provided with a spiral groove containing the spring. The spring and the main bottle body are clamped in the groove. When a bottle opening faces downwards, the situation that as the flexible bottle body is compressed automatically under the action of self weight, and the lubricating grease flows out automatically and contaminates the working environment is avoided.

Description

technical field [0001] The invention relates to a manual lubricating oil supply device, in particular to a grease gun. Background technique [0002] At present, the lubricating grease used for the lubrication of industrial machinery, automobiles, and other equipment is commonly called butter, and most of them are packed in barrels or bags. When in use, it is necessary to take out the grease from the bag or bag and put it into the grease storage cavity of the grease gun. Like this just need to adopt auxiliary equipment in the process of filling, the filling special-purpose shovel of shape as grease gun etc., need cleaning grease gun after filling, also occurred unnecessary waste and environmental pollution simultaneously; On the other hand , Since the filling process of butter is open, it is easy to fall into dust and impurities, which may block the grease nozzle of the grease gun, or may damage the working surface of the equipment after filling it into the equipment.
