DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-6 As shown, a bearing anti-loosening retainer comprises a lower fixing ring 1 and an upper fixing ring 2, the lower fixing ring 1 and the upper fixing ring 2 are connected by a connecting mechanism, a lower groove 11 is provided on the top of the lower fixing ring 1, and an upper groove 21 is provided on the bottom of the upper fixing ring 2, the lower groove 11 and the upper groove 21 are combined to form a mounting groove, the lower fixing ring 1 and the upper fixing ring 2 are combined and connected by the connecting mechanism, the rotor is installed through the mounting grooves of the lower groove 11 and the upper groove 21, a positioning rod 8 is fixedly connected inside the lower groove 11, and an insertion hole corresponding to the positioning rod 8 is provided on the inner top wall of the upper groove 21, the rotor is sleeved on the positioning rod 8 for installation and fixing, the upper fixing ring 2 is separated from the lower fixing ring 1, so as to facilitate the removal of the rotor, after the lower fixing ring 1 and the upper fixing ring 2 are combined, one end of the positioning rod 8 is inserted into the inside of the insertion hole, the stability of the lower fixing ring 1 and the upper fixing ring 2 after combination is improved, and the loosening and shaking are prevented.

[0026] like Figure 2-6The cam 52 is provided on the inner bottom wall of the cam 52 and the cam 53 is provided on both sides of the cam 52.

[0027] like Figure 5-6 As shown, the connecting plug 5 is internally slidably connected to a connecting slide rod 6, a side surface of the limiting slider 51 is fixedly connected to a connecting pull rope 53, the other end of the connecting pull rope 53 is fixedly connected to the connecting slide rod 6, one end of the limiting slider 51 is inclined, and one end of the connecting slide rod 6 extends to the bottom of the connecting plug 5, by pushing the connecting slide rod 6 to slide downward inside the connecting plug 5, one end of the limiting slider 51 is pulled into the inside of the slide groove under the connecting action of the connecting pull rope 53.

[0028] like Figure 1-6 As shown, a movable pressure ring 7 is provided on the top of the upper fixed ring 2, and one end of the connecting slide rod 6 extends to the top of the upper fixed ring 2 and is fixedly connected to the movable pressure ring 7. An annular slide groove is opened on the top of the upper fixed ring 2, and the movable pressure ring 7 is slidably connected to the inside of the annular slide groove. There are multiple connecting slide rods 6, and the multiple connecting slide rods 6 are distributed in a circular array at the bottom of the movable pressure ring 7. By pressing the movable pressure ring 7 to slide inside the annular slide groove, the multiple connecting slide rods 6 are driven to slide down together, and the lower fixed ring 1 and the upper fixed ring 2 can be quickly separated in one time. Multiple second springs are installed inside the annular slide groove, and the multiple second springs are respectively sleeved on the multiple connecting slide rods 6. Through the set second spring, the movable pressure ring 7 can quickly rise and slide due to the elastic force of the second spring when it is not under force.

[0029] It should be noted that, in actual use of the device, the rotor is sleeved on the positioning rod 8, and then the upper fixing ring 2 is installed on the top of the lower fixing ring 1, so that the connecting plug 5 is inserted into the inside of the connecting hole 3, and then the limiting slider 51 is squeezed through the connecting hole 3 to make the limiting slider 51 retract into the inside of the slide groove. When the limiting slider 51 slides to the inside of the limiting hole 4, the rebound of the first spring 54 drives the limiting slider 51 to slide out quickly, and the limiting slider 51 forms a blockage to limit the connection plug 5 from being withdrawn from the inside of the connecting hole 3. Thereby, the combination of the lower fixing ring 1 and the upper fixing ring 2 is quickly completed. After the lower fixing ring 1 and the upper fixing ring 2 are combined, one end of the positioning rod 8 is inserted into the inside of the value insertion hole, which improves the stability of the lower fixing ring 1 and the upper fixing ring 2 after the combination, and prevents them from loosening and shaking. When the lower fixing ring 1 and the upper fixing ring 2 are separated, the movable pressing ring 7 is pressed to push the multiple connecting slide bars 6 to descend together, and under the connection action of the connecting pull rope 53, one end of the limiting slide block 51 is pulled into the inside of the slide groove to release the connection mechanism at one time so that the upper fixing ring 2 can be removed from the top of the lower fixing ring 1.
