[0031] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] Refer to Figure 1 - Figure 3The utility model provides an embodiment: a sealed self -aligning roller bearing, the inner surface front end and rear end of outer ring 1 all rotate and slide and connect with dustproof ring 3, can make two groups of dustproof ring 3 can along the inner surface front end and rear end of outer ring 1 transverse movement and the effect of rotation, the outer surface rear end of dustproof ring 3 is fixedly connected with T block 9, makes dustproof ring 3 when transverse movement and rotation, can drive T block 9 together the effect of movement, the inner surface left side and right side of outer ring 1 all are set with sliding slot 6, makes T block 9 can along the inner surface left side and right side of outer ring 1 slide effect, the outer surface of T block 9 and the inner surface sliding connection of sliding slot 6, makes T block 9 can because with the inner surface sliding of sliding slot 6 and drive dustproof ring 3 along the designated position rotation effect, the inner surface top end of outer ring 1 is provided with fixed assembly, makes T block 9 when rotating to the designated position, can be fixed to the effect of designated position through fixed assembly.

[0033] Refer to Figure 2 , Figure 4 - Figure 5 , fixed assembly still includes inclined block 11, spring 12, connecting rod 13 and knob 5, the outer surface right side of inclined block 11 is elastically connected through spring 12 and the inner surface top end of outer ring 1, makes inclined block 11 can always move outward under the influence of not external force effect, the outer surface top end of inclined block 11 right side is fixedly connected with connecting rod 13, makes connecting rod 13 when transverse movement, can drive inclined block 11 transverse movement effect, the outer surface top end of connecting rod 13 is fixedly connected with knob 5, makes knob 5 when transverse movement, can drive connecting rod 13 drive inclined block 11 transverse movement effect, the outer surface of inclined block 11 and the outer surface of connecting rod 13 all are slidingly connected with the inner surface top end of outer ring 1, makes inclined block 11 and connecting rod 13 can along the inner surface top end of outer ring 1 transverse movement effect, the inner surface contact connection of outer ring 1 has roller 7, makes roller 7 can reduce the friction effect between inner ring 2 and outer ring 1, the outer surface bottom end of roller 7 is rotatably connected with retainer 14, makes roller 7 can along the outer surface rotation effect of retainer 14, the inner surface rotation of retainer 14 is connected with inner ring 2, makes inner ring 2 when rotating, can drive retainer 14 together rotation, and drive roller 7 along the inner surface movement of outer ring 1 effect.

[0034] Refer to Figure 2 - Figure 4The inner ring 2 has sealing rings 8 fixedly connected to both the front and rear ends of its outer surface, enabling the inner ring 2 to drive the two sets of sealing rings 8 to rotate. The dustproof ring 3 has a sealing groove 10 at the rear end of its outer surface, allowing the sealing ring 8 to rotate along the inner surface of the dustproof ring 3. The inner surface of the sealing groove 10 is rotatably connected to the outer surface of the sealing ring 8, preventing external dirt from entering the bearing through the connection between the dustproof ring 3 and the inner ring 2 when the sealing ring 8 and the sealing groove 10 are interlocked. The sliding groove 6 is provided in two sets. One set of sliding groove 6 is a plug-in interface, allowing the T-shaped block 9 to be inserted into the sliding groove 6 through the plug-in interface. The other set of sliding groove 6 is an arc groove, allowing the T-shaped block 9 to always move along a designated position when sliding in the sliding groove 6 due to the restriction of the arc groove.

[0035] Reference Figure 4 - Figure 5 One end of the spring 12 is fixedly connected to the right side of the outer surface of the inclined block 11, and the other end of the spring 12 is fixedly connected to the top of the inner surface of the outer ring 1, so that when the toggle block 5 is stopped, the inclined block 11 can move outward due to the elastic force of the spring 12.

The top of the outer surface of the toggle block 5 is provided with an anti-slip groove, so that when the toggle block 5 is toggle, the friction can be increased and slippage can be prevented.

[0036] Working principle: When replacing the dust cover ring 3, first move the actuating block 5 backward, which will cause the connecting rod 13 to move the inclined block 11 backward, releasing the fixation of the T-shaped block 9. Then rotate the dust cover ring 3 counterclockwise, causing it to move the T-shaped block 9 along the arc groove into the insertion groove. After pulling the old dust cover ring 3 outward, align the T-shaped block 9 at the rear end of the new dust cover ring 3 with the insertion groove on the slide 6, allowing the T-shaped block 9 to move along the inside of the slide 6. Then rotate the dust cover ring 3 clockwise, so that... It drives the T-shaped block 9 to move along the arc groove in the slide 6 to the designated position. When the T-shaped block 9 moves to the designated position, it first squeezes the inclined surface of the inclined block 11, causing the inclined block 11 to move inward, so that the T-shaped block 9 can move to the designated position. When the T-shaped block 9 moves to the designated position, the inclined block 11 will lose its squeezing state and move outward due to the elastic force of the spring 12, and engage with the right side of the outer surface of the T-shaped block 9, so that the T-shaped block 9 can drive the dustproof ring 3 to be fixed in the designated position.

[0037] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
