DETAILED DESCRIPTION

[0020] See also Figure 1-5The utility model provides a hub unit with a magnetically permeable device, comprising a bearing sleeve body 1 and an inner flange 2, wherein the inner flange 2 is installed at the bottom of the bearing sleeve body 1, a magnetically permeable cover 3 is arranged at the top of the bearing sleeve body 1, arc sleeves 4 which are symmetrically distributed are fitted on both sides of the outer circumference of the connection between the bearing sleeve body 1 and the magnetically permeable cover 3, and symmetrically distributed connecting blocks 5 are fixed on the surfaces of the two ends of the arc sleeve 4, and a card slot 9 is provided on the inner circumference of the arc sleeve 4, and the two card slots 9 are connected, and two positioning rings 6 are fitted and inserted inside the two card slots 9, wherein the inner circumference of one positioning ring 6 is fixed to the outer circumference of the magnetically permeable cover 3, and the inner circumference of the other positioning ring 6 is fixed to the outer circumference of the bearing sleeve body 1, wherein slots 14 are provided inside the two connecting blocks 5, and insert blocks 15 are inserted inside the slots 14, and one side of the insert block 15 passes through the adjacent slot 14 and is connected to the other The surfaces of the connecting blocks 5 are fixed, and the two ends of the slot 14 are connected with symmetrically distributed connecting grooves 16, and latch blocks 17 are inserted inside the connecting grooves 16. The surfaces of the two ends of the insert blocks 15 are provided with symmetrically distributed fixing grooves 18, and the ends of the two adjacent position latch blocks 17 that are close to each other extend to the inside of the adjacent position fixing groove 18, and the ends of the two adjacent position latch blocks 17 that are away from each other are fixed with springs 19, and one end of the spring 19 is fixed to the inner cavity of the adjacent position connecting groove 16. When the magnetically permeable cover 3 is placed on the top of the bearing sleeve body 1 to close the interior of the bearing sleeve body 1, the two connecting blocks 5 are sleeved on both sides of the connection between the bearing sleeve body 1 and the magnetically permeable cover 3, and the two connecting blocks 5 can be limited by the insert blocks 15 and the latch blocks 17, so that the magnetically permeable cover 3 can be fixed under the interference between the inner cavity of the slot 9 and the two positioning rings 6.

[0021] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a sealing ring 7 is fixed to the surface of the top of the bearing sleeve body 1, and an annular groove 8 is opened on the surface of the bottom of the magnetic cover 3. The top of the sealing ring 7 passes through the annular groove 8 and fits with the inner cavity surface of the annular groove 8. By placing the magnetic cover 3 on the top of the bearing sleeve body 1 so that the sealing ring 7 can extend to the inside of the annular groove 8, the sealing effect when the bearing sleeve body 1 and the magnetic cover 3 are connected can be improved.

[0022] Further as Figure 3 and Figure 4As shown, it is worth specifically explaining that a through hole 10 is penetrated through the outer circumference of the magnetic permeable cover 3 at the position of the top of the adjacent position positioning ring 6, and a plurality of insertion holes 11 are opened on the outer circumference of the sealing ring 7, and the insertion holes 11 are connected with the interior of the annular groove 8. A plurality of threaded rods 12 are threadedly connected through the outer circumference of the arc sleeve 4, and one side of the threaded rod 12 passes through the adjacent position through hole 10 and extends to the interior of the adjacent position insertion hole 11. A nut 13 is threadedly connected to the outer circumference of the threaded rod 12, and the nut 13 is in conflict with the outer circumference of the arc sleeve 4. Since the through hole 10 is in communication with the inner cavity of the annular groove 8, the nut 13 is rotated so that the nut 13 can pass through the through hole 10 and extend to the interior of the adjacent position insertion hole 11 through the cooperation of the threaded structure on the surface of the arc sleeve 4, and the arc sleeve 4 is further limited by the cooperation of the threaded structure of the nut 13 and the threaded rod 12, thereby reinforcing the magnetic permeable cover 3.

[0023] Further as Figure 5 As shown, it is worth explaining in detail that symmetrically distributed positioning holes 20 are opened on both sides of the surface of one end of the latch block 17, and a limiting shaft 21 is inserted inside the positioning hole 20. The top of the limiting shaft 21 is fixed to the inner cavity surface of the adjacent connecting groove 16. Through the interference between the outer circumference of the limiting shaft 21 and the inner circumference of the adjacent positioning hole 20, the movement trajectory of the latch block 17 can be limited so that it can only move in the vertical direction.

[0024] This solution has the following working process: in actual use, when the user needs to install the magnetic cover 3, the magnetic cover 3 is placed downward from the top of the bearing sleeve body 1, so that the sealing ring 7 can extend to the inner cavity of the ring groove 8 and fit with its inner cavity surface. At this time, the two positioning rings 6 fit each other, and then the arc sleeve 4 fits each other and wraps the connection between the bearing sleeve body 1 and the outer circumference of the magnetic cover 3, and the inner cavity surface of the card groove 9 can buckle the two positioning rings 6. In the process of the two connecting blocks 5 wrapping the connection between the bearing sleeve body 1 and the outer circumference of the magnetic cover 3, the plug block 15 will extend to the inside of the adjacent position slot 14 and contact the adjacent position to cause the spring 19 to deform, so that the pin block 17 completely extends to the inside of the adjacent position connecting groove 16, and then when the adjacent position fixing groove 18 moves to a position close to the pin block 17, the pin block 17 can be embedded in the adjacent position fixing groove 1 under the action of the rebound force of the spring 19. 8, so that the plug block 15 can be reinforced, so that the two arc sleeves 4 can be limited to avoid separation from each other, and the magnetic cover 3 can be fixed under the interference of the inner cavity of the card slot 9 and the two positioning rings 6. Since the through hole 10 is connected with the inner cavity of the ring groove 8, the nut 13 is rotated so that the nut 13 can pass through the through hole 10 and extend to the inside of the adjacent position plug hole 11 through the cooperation of the threaded structure on the surface of the arc sleeve 4, so that the magnetic cover 3 can be reinforced, so that the magnetic cover 3 can be fixed so that it can protect the sending disk. When the magnetic cover 3 needs to be removed, it is only necessary to rotate the nut 13 in the opposite direction to disengage it from the inside of the adjacent position plug hole 11, and then separate the two connecting blocks 5 so that the pin block 17 is disengaged from the inside of the fixing groove 18 under the interference of the connecting groove 16, so that the two arc sleeves 4 are separated, so that the sending disk can be maintained.

[0025] According to the above working process, it can be known that: when the magnetic cover 3 is placed on the top of the bearing sleeve body 1 to close the interior of the bearing sleeve body 1, the two connecting blocks 5 are sleeved on both sides of the connection between the bearing sleeve body 1 and the magnetic cover 3, the two connecting blocks 5 can be limited by the insert block 15 and the latch block 17, so that the magnetic cover 3 can be fixed under the interference of the inner cavity of the slot 9 and the two positioning rings 6, and the nut 13 is extended to the inside of the adjacent position socket 11, so that the fixation of the magnetic cover 3 can be reinforced, thereby being able to protect the magnetic cover 3 while facilitating the installation and removal of the magnetic cover 3, thereby facilitating the maintenance of the transmitter disk, thereby improving the practicality of the device.

[0026] Further Figure 5As shown, it is worth explaining in detail that the two ends of the surface of one side of the plug block 15 are inclined, the inner cavity surface of the fixing groove 18 is semicircular, and the surface of the inner part of the fixing groove 18 of the adjacent position where the latch block 17 is embedded is semicircular. Due to the shape of the plug block 15, the plug block 15 is easy to move in the vertical direction under the interference between the plug block 15 and the latch block 17. Due to the shape of the latch block 17 and the fixing groove 18, the latch block 17 can be prevented from being stuck in the fixing groove 18 when the latch block 17 conflicts with the fixing groove 18.

[0027] In summary, when the magnetic cover 3 is placed on the top of the bearing sleeve body 1 to seal the interior of the bearing sleeve body 1, the two connecting blocks 5 are sleeved on both sides of the connection between the bearing sleeve body 1 and the magnetic cover 3. The two connecting blocks 5 can be limited by the plug block 15 and the latch block 17, so that the magnetic cover 3 can be fixed under the interference between the inner cavity of the slot 9 and the two positioning rings 6, and the nut 13 is extended to the inside of the adjacent position socket 11, so that the fixation of the magnetic cover 3 can be reinforced, thereby the magnetic cover 3 can be protected and the magnetic cover 3 can be installed and removed, so that the maintenance of the sending disk is convenient, thereby improving the practicality of the device, because the shape of the plug block 15 is set, under the interference between the plug block 15 and the latch block 17, the latch block 17 is easy to move in the vertical direction, and because the shape of the latch block 17 and the fixing slot 18 is set, when the latch block 17 conflicts with the fixing slot 18, it can prevent the latch block 17 from being stuck in the fixing slot 18.
