Description

Technical Field

[0001] This utility model belongs to the field of lubricating oil injectors, and specifically relates to a portable lubricating oil injector. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. When an engine is running, if some friction points do not receive proper lubrication, dry friction will occur. Experience has shown that the heat generated by dry friction in a short time is sufficient to melt metal, causing damage to parts or even seizing. Therefore, it is essential to provide proper lubrication to the friction points in the engine.

[0003] Existing technologies have specifically developed some portable lubricant injectors. For example, Chinese patent publication number "CN213040280U" discloses "A Portable Lubricant Injector". The through hole two and the outer cover are opened by a hinge and a press-lock. Lubricant is poured into the main body of the device through the through hole two. The octagonal turntable is rotated by the finger to push the lubricant out of the nozzle. This design is conducive to precise injection of lubricant. With the hanging and anti-slip functions, the device can be hung on the waist or carried in a bag, which is convenient for carrying.

[0004] Although the lubricating oil can be poured into the main body of the device through the through hole two by opening the hinge and pressing the latch, and the lubricating oil can be sprayed out from the nozzle by rotating the octagonal dial with your finger, the lubricating oil cannot be cut off in time when it is sprayed out. This will cause the lubricating oil that has not come out to flow out of the nozzle, which will not only cause waste, but also cause inconvenience to the user. The lubricating oil will drip onto the surface of the user's clothes, which is not easy to clean and cannot effectively improve the use effect. Utility Model Content

After the electric motor 28 starts, the gear 22 fixedly mounted on the output shaft of the electric motor 28 rotates. Since the gear 22 meshes with the toothed plate 20 inside the bottom of the outer ring of the pull rod 8, the pull rod 8 moves after the gear 22 rotates. The pull rod 8 moves into the compression groove 17, thus pushing the lubricating oil through the rubber plug 12 fixedly mounted at one end of the pull rod 8. The lubricating oil is pushed into the compression groove 17 inside the compression head 2. Meanwhile, on the outer ring of the pull rod 8... A first sealing ring 11 and a second sealing ring 13 are provided. With the assistance of the first sealing ring 11 and the second sealing ring 13, air inside the oil storage tank 18 can be prevented from flowing out. This allows the lubricating oil moving inside the compression tank 17 to be effectively compressed, forming thrust. The isolation plate 32, which is attached to one end of the extrusion port 33, is pushed by the lubricating oil flowing inside the extrusion port 33 and the extrusion hole 30. The lubricating oil then enters the discharge port 31 inside the nozzle 1. At this time, the user presses the switch 6 to continue moving the pull rod 8, causing the lubricating oil to flow out from the discharge port 31. This allows for effective application of the lubricant to the parts. After the user stops pressing switch 6, the pull rod 8 will also stop moving. When there is no pushing force, the isolation plate 32 will be pulled back to its original position by the spring 23 inside the cylindrical rod 24. In this way, the isolation plate 32 will return to its original position and fit against one end of the extrusion port 33 and the extrusion hole 30 to effectively isolate the lubricant and prevent more lubricant from leaking. It can also effectively prevent excess lubricant from causing stains to the user. In addition to being convenient, it can also effectively improve the use effect and provide a better user experience.
