Spiral-line-imitative type grease bag

Abstract

The invention discloses a spiral-line-imitative type grease bag which comprises a grease bag body. The grease bag body is provided with a grease injection opening and a grease outlet. According to the spiral-line-imitative type grease bag, lubricating grease can be supplemented for the grease bag through the grease injection opening, the grease bag does not need to be detached from a grease injection device, operation is convenient, and it is avoided that the grease injection bag is taken down repeatedly, and the grease injection device is polluted by dust and the like.

Description

technical field [0001] The invention relates to a grease bag, in particular to a spiral-like grease bag. Background technique [0002] Usually the grease in the grease bag needs to take auxiliary measures to fully inject the grease, such as pressing the oil bag by hand, or using an auxiliary mechanical structure with a pressure plate and a spring, but this process is complicated and difficult to control. If the grease is used up, you need to Replenishment of grease can only be carried out by repeatedly removing the oil bag, which is inconvenient to operate. Repeated removal of the grease bag will easily cause the grease injection equipment to be polluted by dust, etc., resulting in a decline in the quality of the grease. There is an existing grease packaging bottle for grease guns, such as the patent No. As described in the invention patent of CN201410544473.8, the middle part of the bottom of the bottle is thickened, and its area is slightly smaller than the entire area of ...

[0002] Usually the grease in the grease bag needs to take auxiliary measures to fully inject the grease, such as pressing the oil bag by hand, or using an auxiliary mechanical structure with a pressure plate and a spring, but this process is complicated and difficult to control. If the grease is used up, you need to Replenish the oil only by removing the oil bag repeatedly, which is inconvenient to operate. Repeatedly removing the oil bag will easily cause the grease injection equipment to be polluted by dust, etc., resulting in a decline in the quality of the oil. There is an existing grease packaging bottle for grease guns, such as the patent No. As described in the invention patent of CN201410544473.8, the middle part of the bottom of the bottle is thickened, and its area is slightly smaller than the entire area of ​​the bottom of the bottle. The grease gun squeezes the flexible bottle body, so that the bottom of the bottle is equivalent to a piston installed in the bottle. When the grease gun piston is squeezed, it can be pushed to move, so that the grease in the bottle can be fully used

Its shortcomings require external force to squeeze the bottom; the packaging bottle needs to be replaced after the fat injection is completed; the operation is inconvenient
