[0037] The sliding groove 9 is arranged on the end surface 51 and communicates with the embedding groove 7, and the connecting block 10 connected with the limiting block 8 is slidably connected to the inner wall of the sliding groove 9.
[0038] The first elastic member 11 has one end connected to the bottom wall of the embedding groove 7 and the other end connected to the limiting block 8. In the present application, the first elastic member 11 can be a spring or a combination of a spring and a damper.
[0039] In use, before the magnetic ring encoder 3 is installed on the shaft head 4 of the bearing seat 1, the sealing plate 5 is first sleeved on the shaft head 4 of the shaft head hole 2, that is, the shaft head 4 penetrates the through hole 6 of the sealing plate 5, then the connecting block 10 is pushed to move the limiting block 8, at this time the limiting block 8 moves towards the inside of the embedding groove 7 and compresses the first elastic member 11, when the limiting block 8 enters the embedding groove 7, the sealing plate 5 is placed into the shaft head hole 2, then the connecting block 10 is released, and the elastic force of the first elastic member 11 drives the limiting block 8 to move towards the outside of the embedding groove 7, finally the limiting block 8 abuts against the inner wall of the shaft head hole 2, and the sealing plate 5 is stably arranged in the shaft head hole 2 by the abutment of the plurality of limiting blocks 8 against the inner wall of the shaft head hole 2. Then the magnetic ring encoder 3 is installed on the shaft head 4 of the bearing seat 1. The sealing plate 5 can effectively prevent the oil in the shaft head hole 2 from overflowing and polluting the magnetic ring encoder 3, greatly preventing the magnetic ring encoder 3 from counting inaccurately, and keeping the equipment in a good running state. Moreover, the sealing plate 5 also prevents a large amount of short fibers, flying fibers and other waste materials from accumulating in the shaft head hole 2 during operation, reduces the hindrance and consumption of the shaft head 4, ensures the normal use of the shaft head 4, and has high practicability.
[0040] When the sealing plate 5 needs to be removed for maintenance or replacement in the future, the connecting block 10 is pushed to move the limiting block 8 into the embedding groove 7, and then the limiting block 8 is no longer pressed against the inner wall of the shaft head hole 2, so that the sealing plate 5 can be removed. The operation is simple, convenient, time-saving and labor-saving, and has high work efficiency.
[0041] Preferably, please refer to Figure 6 The inner wall of the embedding groove 7 is provided with a moving groove 21, and the moving block 22 connected with the limiting block 8 is slidably arranged on the inner wall of the moving groove 21. In this way, when the limiting block 8 moves, the moving block 22 slides along the moving groove 21, thereby improving the stability and smoothness of the movement of the limiting block 8.
[0042] Preferably, please refer to Figures 3-5 and Figure 7The end surface 51 is further provided with a groove 12 communicated with the sliding groove 9, the connecting block 10 is provided with an operation plate 13, and the operation plate 13 is located in the groove 12. In this way, when the connecting block 10 needs to be pushed, the operation plate 13 in the groove 12 can be pushed, and the operation plate 13 drives the connecting block 10 to move. The operation plate 13 and the connecting block 10 do not protrude out of the end surface 51, so the operation plate 13 can more conveniently drive the connecting block 10 to move.
[0043] Preferably, referring to Figures 3-5 and Figure 7 , the connecting block 10 is further provided with two supporting plates 14, the two supporting plates 14 are rotatably provided with a rotating rod 15, and the rotating rod 15 is provided with a rotating plate 16 connected with the operation plate 13. In this way, when the connecting block 10 needs to be pushed, the operation plate 13 can be rotated, the operation plate 13 is rotated by the rotating plate 16 and the rotating rod 15 to rotate from a direction parallel to the end surface 51 to a vertical direction, that is, the operation plate 13 protrudes out of the end surface 51. At this time, the operation plate 13 and the connecting block 10 can be more conveniently moved, and multiple operation plates 13 can be more conveniently operated, which is good in use effect.
[0044] Preferably, referring to Figures 4-5 and Figure 9 , the groove 12 is further provided with a blocking block 17. In this way, when the operation plate 13 drives the connecting block 10 to move, the limiting block 8 is moved into the embedding groove 7, then the operation plate 13 is moved to be located behind the blocking block 17, and then the operation plate 13 is rotated to be located in the groove 12. At this time, the operation plate 13 is blocked by the blocking block 17, as shown in the state of Figure 9 . At this time, the first elastic member 11 cannot drive the limiting block 8 to move out of the embedding groove 7 due to the limitation of the blocking block 17, so that the cover plate 5 can be more conveniently put into or taken out of the shaft head hole 2, which is more convenient to operate and saves time and effort.
[0045] Preferably, referring to Figure 4 and Figures 7-9 , the side wall of the groove 12 is provided with an inner hidden cavity 18, the inner wall of the inner hidden cavity 18 is slidably connected with a limiting plate 19, and the limiting plate 19 and the bottom wall of the inner hidden cavity 18 are provided with a second elastic member 20. The second elastic member 20 in the application can be a spring.
[0046] In this way, when the operation plate 13 is rotated from the vertical direction to the horizontal direction, the operation plate 13 enters the groove 12, the limiting plate 19 is first pushed to enter the inner hidden cavity 18, the second elastic member 20 is compressed, and when the operation plate 13 passes the limiting plate 19, the limiting plate 19 is released, and the second elastic member 20 restores the limiting plate 19 to its original position, that is, the limiting plate 19 blocks the operation plate 13, as shown in the state ofFigures 7-8 In the illustrated state, the operation plate 13 cannot rotate and escape from the groove 12, so that the rotation of the operation plate 13 during use can be avoided. When the operation plate 13 needs to be rotated later, the limiting plate 19 can be pushed into the inner hidden cavity 18, so that the operation plate 13 can be rotated out of the groove 12, which is simple and convenient.
[0047] Preferably, as shown in Figures 7-8 , the side of the limiting plate 19 facing the end face 51 is a slope. In this way, when the operation plate 13 is rotated from the vertical direction to the horizontal direction relative to the end face 51, the operation plate 13 pushes the slope of the limiting plate 19, so that the limiting plate 19 moves into the inner hidden cavity 18 without manual pushing, which is more convenient and fast.
[0048] Preferably, as shown in Figure 3 and Figure 6 , the outer end face of the limiting block 8 is provided with a plurality of protrusions. In this way, when the limiting block 8 abuts against the inner wall of the shaft head hole 2, the protrusions of the limiting block 8 can increase the friction between the limiting block 8 and the inner wall of the shaft head hole 2, so that the limiting effect on the sealing plate 5 is better.
