[0023] Figures 1-4 This is an embodiment of the utility model, a push rod motor structure, including a mounting seat 1. A protective cover 2 is fixedly installed inside the surface of the mounting seat 1. Two meshing gears 3 are rotatably connected inside the protective cover 2. A sealing cover 4 is fixedly installed on the front surface of the protective cover 2. A servo motor 5 is provided on one side of the surface of the sealing cover 4. The output end of the servo motor 5 is connected to one of the gears 3. A guide tube 6 is fixedly installed on the other side of the surface of the sealing cover 4. A threaded rod 7 is rotatably connected inside the guide tube 6. A telescopic rod 8 is threadedly connected to the surface of the threaded rod 7. A bump 9 is provided at the top of the telescopic rod 8. A lubrication structure 10 is provided at the top of the guide tube 6.
[0024] The specific problem addressed by this specific embodiment is as follows: After the components inside the push rod motor have been moving for a long time, the components will be severely worn, resulting in damage to the components, malfunction of the push rod motor, and reduction in the service life of the components. The utility model utilizes the contact between the convex blocks 9 on the surface of the telescopic rod 8 and the lubrication structure 10 during forward and backward movement. After the convex block 9 contacts the sliding plate 1007, the sliding plate 1007 will squeeze the blocking plate 1005, and the blocking plate 1005 will rotate through the rotating rod 1004. After the blocking plate 1005 rotates, the lubricating oil will flow into the interior of the guide tube 6 through the gap between the blocking plate 1005 and the oil passing plate 1002, lubricating the interior of the guide tube 6, reducing the wear of the threaded rod 7 and the telescopic rod 8, and improving their service life.
[0025] The lubrication structure 10 includes a storage frame 1001 fixedly installed on the top of the guide tube 6. Inside the storage frame 1001, an oil passing plate 1002 is fixedly installed. At the bottom of the oil passing plate 1002, a limiting plate 1003 is fixedly installed. An installation groove is formed on the surface of the limiting plate 1003. In the middle of the installation groove, a rotating rod 1004 is fixedly installed. The surface of the rotating rod 1004 is rotatably connected to a blocking plate 1005. On both sides of the surface of the blocking plate 1005, springs 1006 are fixedly installed. On both sides of the bottom of the blocking plate 1005, sliding plates 1007 are fixedly installed. The convex block 9 is triangular with two inclined sides. When the convex block 9 moves, it contacts the sliding plate 1007. The size of the installation groove formed on the surface of the limiting plate 1003 is larger than the size of the blocking plate 1005. The top of the spring 1006 is connected to the inside of the limiting plate 1003. The top of the storage frame 1001 is provided with a closed cover. On one side of the surface of the closed cover, an oil inlet pipe is fixedly installed. In this specific embodiment, when the convex block 9 on the telescopic rod 8 moves forward and backward, the convex block 9 will squeeze the sliding plate 1007. After the sliding plate 1007 is squeezed, it will squeeze the blocking plate 1005. The blocking plate 1005 will rotate through the rotating rod 1004 inside the limiting plate 1003. When the blocking plate 1005 rotates, there will be a gap between the blocking plate 1005 and the oil passing plate 1002. The lubricating oil inside the storage frame 1001 will enter the interior of the guide tube 6 through the oil passing plate 1002. After entering the guide tube 6, the lubricating oil lubricates the threaded rod 7 and the telescopic rod 8. When the convex block 9 no longer squeezes the sliding plate 1007, the spring 1006 will drive the blocking plate 1005 to automatically reset and block and seal the lubricating oil, which facilitates the lubrication of the threaded rod 7 and the telescopic rod 8 by personnel, reduces wear, and improves the service life.
