[0002] In order to extend the service life of auto parts, lubrication maintenance is required during regular inspection and maintenance of auto parts.

[0003] In order to facilitate the operation of maintenance personnel, the oil lubrication pen is usually in the shape of a needle tube, and a hose is connected to the end of the needle tube. The end of the hose is aligned with the gap of the part that needs lubrication, and the piston rod in the needle tube is pushed to squeeze the lubricating oil inside the needle tube from the hose into the part. After the operation is completed, there will be a small amount of lubricating oil residual in the hose, and the hose diameter is thin, and the lubricating oil has poor fluidity, which makes it impossible to quickly discharge from the inside of the hose by its own gravity, resulting in a waste of lubricating oil. At the same time, it increases the cumbersomeness of cleaning the internal pipes of the lubricated equipment.

[0004] In summary, the present invention provides an oil lubrication device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention aims to provide an oiling lubrication device to solve the problem in the above background technology that the lubricating oil remaining inside the hose cannot be quickly discharged.

[0007] Furthermore, the bottom of the oil injection needle tube is spherically convex downward, the bottom of the piston block is spherically convex downward, and the bottom convex surface is matched with the bottom concave surface of the inner wall of the oil injection needle tube.

[0008] Furthermore, the oil cleaning mechanism includes a connecting pipe, which is threadedly connected to the bottom end of the oil outlet pipe, one side of the connecting pipe is connected to an air intake pipe, one end of the air intake pipe is connected to an air bag, the top of the air bag is connected to an air intake pipe, and the bottom end of the connecting pipe is connected to the oil inlet end of the oil filling hose.

[0009] Furthermore, the connecting pipe is connected to the oil outlet pipe, and the airbag is elliptical.

[0010] Furthermore, a one-way valve is installed on the intake pipe, and a one-way valve is installed on the end of the intake pipe that is connected to the connecting pipe.

[0011] Furthermore, the air intake pipe is bent at a right angle, and the bent end of the air intake pipe is installed upward.

[0012] Beneficial effects of the utility model:

[0013] By manually squeezing the air bag inside the oil cleaning mechanism, gas can be transported from the air intake pipe to the inside of the connecting pipe, and then transported to the inside of the oil filling hose through the connecting pipe. The lubricating oil inside the oil filling hose can be pushed out by air pressure. The air bag can be repeatedly squeezed to continuously transport air to the inside of the oil filling hose and discharge the internal lubricating oil, thereby reducing the waste of lubricating oil during the lubrication process of automotive parts and improving the convenience of cleaning the internal pipes of lubricated equipment.

[0014] The bottom of the oil filling hose is spherical and convex, and the diameter of the oil outlet hole is smaller than the inner diameter of the oil filling hose, resulting in a smaller liquid surface tension at the oil outlet position.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1-3 The utility model provides a technical solution: an oiling lubrication device, including an oiling needle tube 1 and an oiling hose 8, a piston block 2 is embedded in the oiling needle tube 1, and a rubber sleeve 3 is fixed on the outside of the piston block 2. The bottom of the oiling needle tube 1 is connected with an oil outlet pipe 6, and the bottom end of the oil outlet pipe 6 is connected with an oil cleaning mechanism 7. The oiling hose 8 is connected to the bottom end of the oil cleaning mechanism 7, and an oil outlet hole 9 is opened at the bottom end of the oiling hose 8. The top of the piston block 2 is fixedly connected with a push rod 4. The top of the oiling needle tube 1 is open, and the top of the push rod 4 extends to the top of the oiling needle tube 1. A push block 5 is fixedly installed on the top of the push rod 4. The bottom of the oiling hose 8 is spherical and convex, and the diameter of the oil outlet hole 9 is smaller than that of the oiling hose 8. The inner tube diameter causes the liquid surface tension at the oil outlet position to become smaller. When the oil filling hose 8 is not transported by external pressure, the oil inside the oil filling hose 8 will not be discharged from the oil outlet hole 9. The bottom of the oil filling needle tube 1 is spherically convex downward, and the bottom of the piston block 2 is spherically convex downward, and the bottom convex surface is adapted to the concave surface at the bottom of the inner wall of the oil filling needle tube 1, so that the lubricating oil can be quickly and centrally pushed to the oil inlet of the oil outlet pipe 6. The piston block 2 can improve the connection sealing between the piston block 2 and the inside of the oil filling needle tube 1 through the rubber sleeve 3, and when the piston block 2 moves down through the rubber sleeve 3 and fits the bottom of the inner wall of the oil filling needle tube 1, all the lubricating oil in the oil filling needle tube 1 can be squeezed into the oil outlet pipe 6.

[0023] See also Figure 2-3 The oil cleaning mechanism 7 includes a connecting pipe 71, which is threadedly connected to the bottom end of the oil outlet pipe 6. One side of the connecting pipe 71 is connected to an air inlet pipe 72. One end of the air inlet pipe 72 is connected to an air bag 73. The top of the air bag 73 is connected to an air suction pipe 74. The bottom end of the connecting pipe 71 is connected to the oil inlet end of the oil filling hose 8. The connecting pipe 71 is connected to the oil outlet pipe 6. The air bag 73 is oval in shape, which is convenient for hand-held squeezing of the air bag 73. A one-way valve is installed on the air suction pipe 74. A one-way valve is installed on the end of the air inlet pipe 72 connected to the connecting pipe 71. 2 is bent at a right angle, and the bent end of the air intake pipe 72 is installed upward. The air bag 73 is made of rubber and has an elastic deformation recovery effect. The one-way valve on the air intake pipe 72 can only ensure that the air inside the air bag 73 is transported to the inside of the connecting pipe 71, and the oil inside the connecting pipe 71 cannot flow back to the inside of the air bag 73 through the air intake pipe 72. The one-way valve on the intake pipe 74 only allows the air bag 73 to recover from its deformation, using negative pressure to extract external air and squeeze the air bag 73. The air inside the air bag 73 cannot be discharged from the intake pipe 74.

[0024] Specific implementation method: By rotating the oil cleaning mechanism 7 as a whole in the opposite direction, the connecting pipe 71 is removed from the bottom end of the oil outlet pipe 6, and the bottom end of the oil outlet pipe 6 is inserted into the lubricating oil inside the lubricating oil barrel, and the push block 5 is pulled upward. The push block 5 drives the push rod 4 to move upward, and the push rod 4 drives the piston block 2 to move upward. While the piston block 2 slides upward inside the oil filling needle tube 1 through the rubber sleeve 3, a negative pressure is formed below the inside of the oil filling needle tube 1, so that the lubricating oil in the lubricating oil barrel can be extracted from the oil outlet pipe 6. After the extraction is completed, the top end of the connecting pipe 71 inside the oil cleaning mechanism 7 is aligned with the oil outlet pipe 6, and rotated and tightened to achieve connection.

[0025] Align the oil outlet hole 9 at the bottom end of the oil filling hose 8 with the gap of the automobile parts that need lubrication, push the push block 5 downward with your thumb, the push block 5 pushes the push rod 4 to move downward, and the push rod 4 pushes the piston block 2 to move downward. The piston block 2 can squeeze the lubricating oil inside the oil filling needle tube 1 into the inside of the oil outlet pipe 6 through the rubber sleeve 3, and squeeze it into the inside of the connecting pipe 71 through the oil outlet pipe 6. The connecting pipe 71 transports the oil to the inside of the oil filling hose 8 and discharges it through the oil outlet hole 9. The aperture of the oil outlet hole 9 is smaller than the inner diameter of the oil filling hose 8, so that the sprayed lubricating oil beam can be thinner, which is convenient for precise lubrication spraying of the gaps of automobile parts.

[0026] When the bottom of the piston block 2 is completely fitted with the bottom of the inner wall of the oil filling needle tube 1 through the rubber sleeve 3, the oil inside the oil filling needle tube 1 has been completely squeezed out. However, there is still a small amount of lubricating oil in the oil filling hose 8. In order to avoid wasting the lubricating oil, the air bag 73 inside the oil cleaning mechanism 7 can be squeezed by hand, so that the gas can be transported from the air inlet pipe 72 to the inside of the connecting pipe 71, and the gas is transported to the inside of the oil filling hose 8 through the connecting pipe 71. The lubricating oil in the oil filling hose 8 can be pushed out by air pressure. When the air bag 73 is released, the air bag 73 is made of rubber and has an elastic deformation recovery effect. The single piece on the air inlet pipe 72 The one-way valve can only ensure that the air inside the airbag 73 is transported to the inside of the connecting pipe 71, and the oil inside the connecting pipe 71 cannot flow back to the inside of the airbag 73 through the intake pipe 72. The one-way valve on the intake pipe 74 only allows the airbag 73 to deform and recover, and to use the negative pressure to extract the external air and squeeze the airbag 73. The air inside the airbag 73 cannot be discharged from the intake pipe 74. The air can be continuously transported to the inside of the oil filling hose 8 and the internal lubricating oil can be discharged by repeatedly squeezing the airbag 73, which reduces the waste of lubricating oil during the lubrication of automobile parts and improves the convenience of cleaning the internal pipes of lubricating equipment.

[0027] The bottom of the oil filling hose 8 is in the shape of a spherical protrusion, and the diameter of the oil outlet hole 9 is smaller than the inner diameter of the oil filling hose 8, resulting in a smaller liquid surface tension at the oil outlet position. When the inside of the oil filling hose 8 is not subjected to external pressure to transport oil, the oil inside the oil filling hose 8 will not be discharged from the oil outlet hole 9, thereby reducing the phenomenon of lubricating oil dripping everywhere and improving the quality of the lubrication processing environment for automotive parts.

[0028] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
