Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a runner contact type movable sealing strip comprises a rotating shaft 1, a bearing 2 and a sleeve shaft 3, wherein the rotating shaft 1 is rotatably installed in the sleeve shaft 3 through the bearing 2, sealing rings 4 are fixedly connected at two ends of the sleeve shaft 3, worm wheels 5 are symmetrically and fixedly connected at two sides of the bearing 2, two rotating rods 6 are symmetrically and rotatably installed in the sleeve shaft 3 and are respectively located at two sides of the bearing 2, worms 7 are fixedly connected on the rotating rods 6, the worm wheels 5 are meshed with the worms 7, two rotary tables 8 are symmetrically and fixedly connected on the rotating rods 6, the two rotary tables 8 are respectively located at two sides of the worms 7, rotating strips 9 are fixedly connected on the rotary tables 8, two connecting plates 10 are symmetrically and fixedly connected on the sleeve shaft 3, the two connecting plates 10 are respectively located at two sides of the bearing 2, a sliding rod 11 is slidably installed on the connecting plates 10, a push plate 14 is fixedly connected at one end, close to each other, of the sliding rod 11 is fixedly connected with a sliding plate 12, the rigid coupling has reset spring 13 between slide 12 and the connecting plate 10, the machine oil in the bearing 2 is because of receiving the influence of gravity, and pivot 1 during operation probably makes bearing 2 receive and rock, make the machine oil in the bearing 2 flow out, when pivot 1 rotates, thereby drive worm wheel 5 and rotate, thereby make worm 7 rotate, make disc 8 rotate, thereby make commentaries on classics strip 9 rotate, when commentaries on classics strip 9 rotates and push pedal 14 contact, make push pedal 14 take slide 11 to remove, make slide 11 take slide 12 to remove towards the direction of bearing 2, make slide 12 push away the machine oil and remove towards the direction of bearing 2, because of inertial reason, make machine oil pushed away again in bearing 2, prevent that machine oil from permeating the gap of sealing washer and flowing to the external world, thereby pollute the external world, make inside leakproofness better.

The distance from the sliding plate 12 to the connecting plate 10 is smaller than the distance from the push plate 14 to the bearing 2, so that when the rotating strip 9 makes the push plate 14 move, the push plate 14 is prevented from contacting the bearing 2, and the inner cylinder of the bearing 2 rotates, so that the push plate 14 is prevented from being damaged.

Set up on the slide 12 with change breach 15 that strip 9 corresponds, convenient when changeing strip 9 and changeing with breach 15 contact time for change that strip 9 can be quick make push pedal 14 promote towards bearing 2's direction, enable more in the machine oil slides bearing 2, make bearing 2 effect when rotating better, increase bearing 2's life has also strengthened inside leakproofness.

Slide

12 and 3 sealing sliding connection of sleeve shaft, slide also can the separation engine oil one defense line, prevent that engine oil from contacting the sealing washer, have the possibility of flowing, also can make things convenient for slide 12 to slide, make things convenient for push pedal 4 to push away the engine oil fast in the bearing 2, increased bearing 2's life.

An oil absorption towel 16 is fixedly connected below the push plate 14, and the oil absorption towel 16 can absorb the engine oil at the lower end, so that when the slide plate 12 rapidly pushes the push plate 14, the engine oil on the oil absorption towel 16 is thrown into the bearing 2 due to the action of inertia, the shaft is prevented from being exhausted, and the sealing performance of the inside is better.

Those not described in detail in this specification are within the skill of the art.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
