Embodiment Construction
[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.
[0033] like Figure 1 to Figure 2 As shown, a grease gun includes an oil storage cylinder 5 and an end cap 9, the oil storage cylinder 5 is made of a transparent material, a piston 3, a piston rod 6 and a spring 4 are arranged in the oil storage cylinder 5, and the piston 3 adopts Made of NBR rubber, the piston rod 6 is axially installed in the oil storage cylinder 5, the spring 4 is sleeved outside the piston rod 6, the piston rod 6 is connected with the piston 3, the piston 3 restricts the spring 4 in the oil storage cylinder 5, The oil storage cylinder 5 is screwed and matched with the end cover 9, and the end cover 9 is a plastic part. A lever type oil outlet mechanism 7 and an oil outlet pipe 8 are arranged on the end cover 9, and the end cover 9 is hingedly matched with the lever type oi...

The invention relates to manual lubricant supply devices, particularly to a grease gun. The grease gun is composed of a grease storage tube and an end cover. The grease storage tube is made of transparent materials, a piston, a piston rod and a spring are arranged inside the grease storage tube, wherein the piston rod axially penetrates the grease storage tube, the spring sleeves the piston rod, the piston rod is connected with the piston, and the piston limits the spring inside the grease storage tube; the grease storage tube is threadedly matched with the end cover, the end cover is made of plastics and provided with a lever type grease output mechanism and a grease outlet pipe; a grease package bottle is arranged inside the grease storage tube and composed of a bottle body and a bottle cover, wherein the bottle body comprises a bottle body unit and a bottle bottom and is flexible, and a plurality of hard ring-shaped portions are formed in the axial direction of the bottle body unit and are higher in hardness than other portions of the bottle body unit. By means of the structure above, the bottle body can avoid inward recession to form extrusion dead zones due to flexible materials, and further waste of lubricating grease inside the dead zones can be 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. Con...
