[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. When mechanical components are operating, if some friction parts do not receive proper lubrication, dry friction will occur. Practice has proved that the heat generated by dry friction in a short period of time is sufficient to melt metal, causing damage or even jamming of machine parts. Therefore, it is necessary to implement a lubricating oil filling device to provide good lubrication for the friction parts of mechanical components.

[0003] After retrieval, a lubricating oil filling device with the publication number CN219655811U includes a loading tank. The inner bottom wall of the loading tank is fixedly connected with an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected with a stabilizing plate. The upper surface of the stabilizing plate is fixedly connected with a pushing plate. The outer surface of the pushing plate is fixedly connected with a sealing ring. The upper surface of the loading tank is fixedly communicated with an oil guide pipe. The end of the oil guide pipe far away from the loading tank is fixedly communicated with an electromagnetic valve. The inside of the loading tank is fixedly inlaid with tempered glass. The upper surface of the loading tank is threadedly connected with a sealing plug. The bottom surface of the loading tank is fixedly connected with a base. Through the cooperation of the electric telescopic rod, the stabilizing plate, the pushing plate, the oil guide pipe, the electromagnetic valve, and the sealing ring, the device can automatically fill lubricating oil. The cooperation of the tempered glass and the scale can facilitate the staff to check the remaining amount of lubricating oil inside the loading tank;

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: A portable lubricating oil injection device includes:

[0028] The top of the oil storage cylinder 1 is provided with a lid 2. A sliding rod 3 is slidably connected inside the lid 2. A pressing disc 11 is threadedly connected to the bottom end of the sliding rod 3. Anti-slip patterns are provided on the outer walls of the fixed block and the pressing disc 11 to increase the friction between the outer walls of the pressing disc 11 and the upper pressing disc 9. The upper pressing disc 9 located on the top side of the rubber pad 10 is threadedly connected to the outer wall of the sliding rod 3. A fixed block is fixedly connected to the top side of the upper pressing disc 9 to fix the rubber pad 10. The top end of the lid 2 is fixedly connected to a pressing plate 4 to drive the downward pressing of the sliding rod 3. A plurality of anti-slip strips 13 are fixedly connected to the outer wall of the middle section of the oil storage cylinder 1 to increase the friction of the outer wall of the oil storage cylinder 1. A filter plate 12 is fixedly connected to the inner wall of the middle section of the oil outlet head 6 to filter the lubricating oil before the oil injection operation. The radius of the bottom end of the pressing disc 11 is smaller than the inner radius of the connecting head 5;

[0029] Specifically, the operator holds the outer wall of the oil storage cylinder 1 with one hand, and then drives the sliding rod 3 to slide inside the lid 2 by pressing the pressing plate 4, so as to drive the rubber pad 10 to rise and fall on the inner wall of the oil storage cylinder 1. By cooperating with the oil storage cylinder 1, the connecting head 5 and the lid 2 through the rubber pad 10, a sealed space can be formed to suck the lubricating oil and inject the lubricating oil inside the oil storage cylinder 1 to the required position. The oil injection operation is realized through a simple structure, which is convenient to improve the convenience of the lubricating oil injection device and the efficiency of lubricating oil injection. At the same time, by rotating the upper pressing disc 9 so that the upper pressing disc 9 rotates to the middle section of the sliding rod 3, and then screwing off the bottom end of the sliding rod 3 with the pressing disc 11, the rubber pad 10 can be disassembled from the bottom end of the sliding rod 3, which is convenient to replace the damaged rubber pad 10 in time to avoid the damaged rubber pad 10 affecting the sucking and injection of the lubricating oil.

[0030] Refer to Figures 2 - 4 As shown in the figure, the connecting head 5 is fixedly connected to the bottom end of the oil storage cylinder 1. An oil outlet head 6 is threadedly connected to the bottom end of the connecting head 5. A connecting rope 7 is located on the outer wall of the oil outlet head 6. One end of the connecting rope 7 is fixedly connected to a plug 8 to prevent the lubricating oil from leaking out of the opening of the oil outlet head 6. Anti-slip patterns are provided on the outer walls of the fixed block and the pressing disc 11 to increase the friction between the outer walls of the pressing disc 11 and the upper pressing disc 9;

[0031] Specifically, after the oil outlet head 6 and the connecting head 5 are connected by threads, the lubricating oil can be injected through the oil outlet head 6. At the same time, when the lubricating oil injection device is not in use, the bottom end of the oil outlet head 6 can be blocked by the plug 8 to improve the sealing performance of the lubricating oil injection device. At the same time, when the rubber pad 10 needs to be disassembled and replaced, by rotating the upper pressing disc 9 and the pressing disc 11, the pressing disc 11 can be disassembled from the bottom end of the sliding rod 3, which is convenient to disassemble the rubber pad 10 from the bottom end of the sliding rod 3.

[0032] Working principle: The staff holds the outer wall of the oil storage cylinder 1 with one hand, and then drives the sliding rod 3 to slide inside the lid 2 by pulling up the pressing plate 4, which can drive the rubber pad 10 to rise on the inner wall of the oil storage cylinder 1, so as to suck the lubricating oil into the inside of the oil storage cylinder 1. Then, block the opening of the oil outlet head 6 with the plug 8. When oil injection is needed, first remove the plug 8, and then drive the sliding rod 3 and the rubber pad 10 to descend inside the oil storage cylinder 1 by pressing down the pressing plate 4, so as to press out the lubricating oil inside the oil storage cylinder 1 through the connector 5 and the oil outlet head 6, realizing the operation of discharging the lubricating oil.
