[0016] The following is combined with Figure 1-3 This application is described in further detail.

[0017] An embodiment of the present application discloses a lubrication device for an elevator door machine system, including a door body 1 and a door frame 2. The door body 1 can move horizontally relative to the door frame 2. An oil chamber 15 is provided at the top of the door body 1. A plurality of groups of conduits 11 are fixedly connected to the bottom of the oil chamber 15. The conduits 11 are arranged horizontally and equidistantly along the moving direction of the door body 1. The outlet ends of the conduits 11 are all located on the side where the surface of the door body 1 contacts the door frame 2. A first switch mechanism is provided inside the oil chamber 15, and the first switch mechanism is used to control the on and off of the upper end of the conduit 11; a second switch mechanism is provided on the outer surface of the door body 1, and the second switch mechanism is used to control the on and off of the lower end of the conduit 11.

[0018] In this embodiment, the oil chamber 15 is used to store lubricating oil. By setting a first switch mechanism and a second switch mechanism, each time lubrication is performed, the lubricating oil in the oil chamber 15 is first introduced into the conduit 11 for temporary storage through the first switch mechanism. After closing the first switch mechanism, the first switch mechanism is closed again and the second switch mechanism is opened. The lubricating oil inside the conduit 11 can flow into the surface of the door body 1. Since the conduits 11 are equidistantly arranged on the surface of the door body 1, it can relatively ensure that the lubricating oil in various areas of the surface of the door body 1 is relatively uniform. When the door body 1 moves horizontally relative to the door frame 2, the lubricating oil in various areas of the surface of the door body 1 can be evenly applied.

[0019] Furthermore, the first switching mechanism includes a baffle 9 that is installed in cooperation with the bottom of the oil chamber 15. A plurality of through holes 12 are provided on the surface of the baffle 9. The through holes 12 are arranged in a one-to-one correspondence with the conduits 11. A moving mechanism is provided between the baffle 9 and the oil chamber 15. The moving mechanism aligns or staggers the through holes 12 with the upper end of the conduit 11.

[0020] Furthermore, the moving mechanism includes a slide groove 3 opened on the surface of the door frame 2, one end of the baffle 9 passes through the side wall of the door body 1 and is fixedly connected to an L-shaped plate 6, one end of the L-shaped plate 6 is slidably fitted inside the slide groove 3, and the other end of the L-shaped plate 6 is fixedly connected to a guide rod 10, one end of the guide rod 10 is slidably inserted inside the door body 1, and a spring 7 is sleeved on the surface of the guide rod 10, one end of the spring 7 is fixedly connected to the door body 1, and the other end of the spring 7 is fixedly connected to the L-shaped plate 6.

[0021] In this embodiment, when the door body 1 is closed, the L-shaped plate 6 is located at the end of the slide groove 3, the spring 7 is in the original state, the through hole 12 on the baffle 9 and the upper end of the conduit 11 are in a staggered state, and the conduit 11 is closed at this time. When the door body 1 is opened, the L-shaped plate 6 is located at the head end of the slide groove 3, the spring 7 is in a stretched state, the through hole 12 on the baffle 9 and the upper end of the conduit 11 are aligned. At this time, the upper end of the conduit 11 is connected to the oil chamber 15, and the lubricating oil in the oil chamber 15 can flow into the inside of the conduit 11 and be temporarily stored.

[0022] Furthermore, the second switch mechanism includes multiple groups of sealing plates 13, which correspond one-to-one to the lower ends of the conduits 11, and the bottoms of the sealing plates 13 are fixedly connected to vertical plates 14, the tops of the vertical plates 14 are rotatably connected to the door body 1 through rotating shafts, and torsion springs are provided on the surfaces of the rotating shafts. A push plate 8 is fixedly connected to the position where the surface of the door frame 2 is aligned with the bottom of the vertical plates 14.

[0023] In this embodiment, when the door body 1 moves and closes relative to the door frame 2, when the vertical plate 14 passes through the push plate 8, the vertical plate 14 will be deflected by the interference of the push plate 8, thereby causing the sealing plate 13 to rotate around the rotating axis, so that the lower end of the conduit 11 is opened, and the lubricating oil in the conduit 11 can flow into the surface of the door body 1, and in the process of the door body 1 moving relative to the door frame 2, the lubricating oil on the surface of the door body 1 can be evenly applied.

[0024] Furthermore, a groove 4 is formed on the surface of the door frame 2 , and a cleaning roller 5 is rotatably connected to the inside of the groove 4 , and the bristles of the cleaning roller 5 are partially located outside the groove 4 .

[0025] In this embodiment, by providing a cleaning roller 5 , when the door body 1 moves relative to the door frame 2 , the cleaning roller 5 rotates under the action of friction force, and the rotation of the cleaning roller 5 can further spread the lubricating oil on the surface of the door body 1 .
