[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-2 As shown, this utility model provides a single-point automatic lubricator, including an oil bottle shell 2. A protective cover 1 is rotatably mounted on the top of the oil bottle shell 2 via a thread. Rotating the protective cover 1 counterclockwise separates it from the oil bottle shell 2. A No. 1 O-ring waterproof ring 11 is provided between the oil bottle shell 2 and the protective cover 1. The No. 1 O-ring waterproof ring 11 is made of nitrile rubber, which meets the requirements of waterproofing and oil resistance while greatly reducing costs. A filling port 22 is provided on the top of the oil bottle shell 2, and an oil plug is rotatably mounted on one end of the filling port 22. By providing the filling port 22... The oil plug is rotated counterclockwise to separate it from the filling port 22, allowing lubricating oil to be added to the oil bottle shell 2. The bottom of the oil bottle shell 2 has an oil drain port 21, which is conical. This conical shape reduces resistance to oil flow. A connector adapter 19 is threadedly mounted at the bottom of the oil drain port 21. One end of the connector adapter 19 engages with the threaded connection at the oil drain port 21, while the other end can be fitted with different models of connector adapters depending on the machine interface used, making it more flexible and improving lubrication. The application range is wider. The connector adapter 19 is made of nickel-plated copper, which can effectively prevent corrosion and oxidation in complex environments, increase the service life of the product, and save on usage costs to another extent. An oil bottle stopper 16 is slidably installed in the inner cavity of the top of the oil bottle shell 2. When the oil bottle stopper 16 descends vertically in the inner cavity of the oil bottle shell 2, it can squeeze the lubricating oil in the inner cavity of the oil bottle shell 2. The squeezed lubricating oil is discharged downward through the oil outlet 21 (when the oil bottle stopper 16 is stationary, the lubricating oil in the inner cavity of the oil bottle shell 2 cannot pass through the oil outlet 21). (Discharges downwards, similar to the principle of a syringe). After the protective cover 1 separates from the oil bottle shell 2, the oil bottle slide plug 16 can also separate from the oil bottle shell 2 along with the protective cover 1 and the external hexagonal threaded rod 17. When the oil bottle slide plug 16 is rotated individually, it can be disengaged from the external hexagonal threaded rod 17, allowing the oil bottle slide plug 16 to be replaced. A No. 2 O-ring waterproof ring 12 and a No. 3 O-ring waterproof ring 13 are respectively provided between the oil bottle slide plug 16 and the inner wall of the oil bottle shell 2. The No. 2 O-ring waterproof ring 12 and the No. 3 O-ring waterproof ring 13 have the same function as the No. 1 O-ring waterproof ring 11.

[0022] A housing 7 is detachably installed inside the inner cavity of the protective cover 1 via screws. The bottom end of the housing 7 extends to the top inner cavity of the oil bottle shell 2. The bottom end of the housing 7 and the top inner cavity of the oil bottle shell 2 are fitted with a close-fitting toothed engagement, which can effectively counteract the radial rotational force when the motor 3 rotates. The motor 3 is detachably installed inside the housing 7 via screws. By setting the housing 7 and motor 3 detachably, the housing 7 and motor 3 can be disassembled separately after the protective cover 1 is separated from the oil bottle shell 2 for easy maintenance. A battery 4 and PCBA 8 are detachably installed inside the housing 7. The motor 3 is electrically connected to the battery 4 via a wiring harness, and the battery 4 can power the motor 3. The battery 4 is connected to the PCBA 8 via a plastic connector. An external PLC controller can control the start and stop of the motor 3 through a signal connection with the PCBA 8. A metal adapter 15 is fixedly provided at the drive output end of the motor 3. A hexagonal groove 151 is provided at the end of the metal adapter 15 away from the drive output shaft of the motor 3. An external hexagonal threaded rod 17 is provided in the inner cavity. One end of the external hexagonal threaded rod 17 is movably connected to the inner wall of the hexagonal groove 151 and is detachably installed in the hexagonal groove 151 by bolts. The external hexagonal threaded rod 17 can be disassembled by the bolts, so that the external hexagonal threaded rod 17 can be separated from the metal adapter 15. By setting the metal adapter 15 and the hexagonal groove 151, the metal adapter 15 can reduce the direct wear of the motor 3 and save repair costs. The external hexagonal threaded rod 17 is easier to standardize by using external hexagonal, and at the same time, it is made of stainless steel, which has better material strength and increases product life. The external hexagonal threaded rod 17 passes through the oil bottle slide plug 16 and is threadedly connected to the oil bottle slide plug 16. When the motor 3 is started, the drive shaft of the motor 3 rotates the external hexagonal threaded rod 17 through the metal adapter 15. The external hexagonal threaded rod 17 can drive the oil bottle slide plug 16 to descend vertically, squeezing the lubricating oil in the oil bottle shell 2. The lubricating oil is discharged through the oil drain port 21, achieving the purpose of adding lubricating oil.
