[0002] In modern production, improving production efficiency is an important goal pursued by enterprises. Lubricators can achieve quantitative and fixed-point lubrication, reduce equipment downtime caused by insufficient or excessive lubrication, and thus improve production efficiency. At the same time, its automated lubrication method can also reduce the tediousness and errors of manual operation, further improving production efficiency.

[0003] With the continuous progress of the machinery manufacturing industry, the requirements for lubrication technology are getting higher and higher. The oiler adopts advanced lubrication technology, which can achieve precise lubrication control and ensure that each lubrication point can get the right amount of lubricant. The application of this precise lubrication technology helps to improve the performance and reliability of the equipment and extend the service life of the equipment.

[0004] However, from a technical point of view, although the existing lubricators can complete basic lubrication tasks, their performance and stability still need to be improved in some special working environments. For example, in high temperature, high pressure or high humidity environments, the sealing and durability of the lubricator may be affected, resulting in reduced lubrication effect or failure. Secondly, the maintenance and management of the lubricator is also a challenge. During long-term use, the lubricator may require regular maintenance and replacement of parts due to problems such as wear, blockage or leakage. However, due to the complex structural design of some lubricators, maintenance operations may be relatively cumbersome, increasing maintenance costs and time costs.

[0005] Therefore, the applicability and flexibility of the oil feeder in the prior art also need to be improved. Utility Model Content

[0039] The end of the housing 200 is provided with an oil outlet 210 corresponding to Figure 3 As shown, an oil outlet 210 is provided at the upper end of the housing 200;

[0040] Continue as Figure 3 As shown, the main body 100 is inserted and installed in the housing 200 from bottom to top, and an axial distribution (i.e. Figure 3 A first oil chamber 101 (distributed up and down) that runs through both ends of the main body 100 is formed with an oil outlet channel 102; the first oil chamber 101 is connected to the oil outlet 210 through the oil outlet channel 102.

[0041] The piston rod 300 is installed in the first oil chamber 101 of the main body 100, and the piston rod 300 can move in the first oil chamber 101. Figure 3 Move up and down;

[0042] The steel sleeve 400 is installed between the main body 100 and the housing 200. A sealing ring 410 is provided approximately in the middle of the steel sleeve 400. A first chamber 201 and a second chamber 202 are formed between the outer wall of the steel sleeve 400 and the inner wall of the housing 200.

[0043] Furthermore, the first chamber 201 is connected to the first oil chamber 101 and the oil outlet channel 102 via the first flow channel 01 , and the second chamber 202 is connected to the first oil chamber 101 and the oil outlet channel 102 via the second flow channel 02 .

[0044] The piston rod 300 can be moved to a first position and a second position. Figure 5 As shown, in the first position, the piston rod 300 controls the first flow channel 01 to be disconnected and the second flow channel 02 to be connected. At this time, the second chamber 202 is connected to the first oil chamber 101 and the oil outlet channel 102 through the second flow channel 02;

[0045] like Figure 6 As shown, in the second position, the piston rod 300 controls the first flow channel 01 to be connected and the second flow channel 02 to be disconnected. At this time, the first chamber 201 is connected to the first oil chamber 101 and the oil outlet channel 102 through the first flow channel 01.

[0046] Furthermore, the first oil chamber 101 is connected to the oil outlet channel 102 through the first flow channel 01 and the second flow channel 02 .

[0047] Furthermore, it also includes: a sealing plug 600, a steel ball 500, a steel sleeve 400 and an end cover 700;

[0048] like Figure 3 As shown, the sealing plug 600 is installed on the main body 100 and seals the end of the first oil chamber 101;

[0049] The steel ball 500 is installed in the oil outlet 210 of the housing 200 , and the steel ball 500 is pushed open by oil pressure to allow the fluid to flow out of the oil outlet 210 .
