[0025] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.

[0026] Reference Figure 1The present invention provides a portable lubricator for lubricating bolts on rails. The lubricator comprises a barrel 1, an oil outlet pipe 2, and an oil control assembly 3. The barrel 1 can store rust-proof oil, the oil outlet pipe 2 can discharge the rust-proof oil, and the oil control assembly 3 can discharge the rust-proof oil during use. When lubricating is not in progress, the oil outlet pipe 2 can be sealed to prevent leakage of the rust-proof oil.

[0027] Reference Figure 2 The cylinder 1 includes a first oil storage part 11, a second oil storage part 12 and a fixing part 13. The first oil storage part 11 is fixed above the second oil storage part 12, and the fixing part 13 is located below the second oil storage part 12. The oil drain pipe can be fixed to the inside of the fixing part 13 by rivets, so that the oil drain pipe can be connected to the inside of the cylinder 1.

[0028] As an embodiment, the first oil reservoir 11 is cylindrical, and the second oil reservoir 12 is inverted conical, so that the rust-proof oil can flow out smoothly when lubricating the bolts. It should be noted that the structure of the cylinder body 1 does not necessarily need to be divided into the first oil reservoir 11 and the second oil reservoir 12 as described above. It can also adopt a generally cylindrical structure, as long as it can store the rust-proof oil and can be connected to the oil outlet pipe 2 for oil discharge.

[0029] A semi-annular handle 14 is provided above the cylinder 1, and both ends of the handle 14 are rotatably connected to the cylinder 1. Specifically, the handle 14 is provided on the first oil storage portion 11, and the handle 14 can facilitate the oiler to be moved and oiled on different bolts. Furthermore, the upper end of the cylinder 1 is open, and a closing cover 15 is provided at the upper end opening of the cylinder 1. The closing cover 15 can close the cylinder 1, and the closing cover 15 can be opened to add rust-proof oil to the cylinder 1. It should be noted that the upper end structure of the cylinder 1 is not limited to this, and the upper end of the shell can also be a closed structure, and an additional refueling pipe is used to add oil to the interior of the cylinder 1.

[0030] Reference Figure 3 The oil control assembly 3 includes a pressing ball 31, a spring 32, and a mounting block 33. A rivet on the fixing portion 13 extends into the oil outlet pipe 2 to secure the mounting block 33. A gap is created between the outer periphery of the mounting block 33 and the oil outlet pipe 2. The spring 32 is positioned between the pressing ball 31 and the mounting block 33, with its ends secured to the pressing ball 31 and the mounting block 33, respectively.
