[0034] Refer to Figure 2 - Figure 4 , the fixing component includes a bolt 51, a moving ring 52 is elastically connected to the inner wall of the connecting ring 4 through a compression spring 53, the fixing component further includes a clamping block 54, a clamping groove 501 is opened on the lower surface of the bolt 51, and both the clamping block 54 and the clamping groove 501 are provided with multiple groups, which are arranged in a circumferential array with the center of the bolt 51 as the center. A rubber pad 55 is inserted into the upper surface of the connecting ring 4, and a pressing block 56 is fixedly connected to the upper surface of the rubber pad 55. The rubber pad 55 is slightly larger than the opening on the upper surface of the connecting ring 4. When inserted, the rubber pad 55 will be deformed by extrusion and fit with the inner wall of the connecting ring 4. The rubber pad 55 is located above the bolt 51 and can play a sealing role to prevent dust and water vapor from corroding the bolt 51, enhancing the stability of the device during use and the service life of the bolt 51.
[0035] Refer to Figure 1 、 Figure 2 、 Figure 5 , the positioning component includes an insertion block 61, a limiting block 63 is elastically connected to the inner wall of the insertion block 61 through a connecting spring 62, a slot 601 is opened on the right surface of the anti-detachment plate 1, the insertion block 61 and the slot 601 fit, and a limiting groove 602 is opened inside the anti-detachment plate 1, and the limiting groove 602 and the limiting block 63 fit.
[0036] Refer to Figure 2 - Figure 4, the connecting ring 4 is sleeved on the outer wall of the guide wheel shaft 3. The bolt 51 penetrates and is threadedly connected to the upper surface of the connecting ring 4, and the bolt 51 also penetrates and is threadedly connected to the upper surface of the guide wheel shaft 3. The moving ring 52 is slidably connected to the inner wall of the connecting ring 4, sliding longitudinally. One end of the compression spring 53 is fixedly connected to the lower surface of the moving ring 52, and the other end of the compression spring 53 is fixedly connected to the inner wall of the bottom end of the connecting ring 4. When the moving ring 52 moves downward, it will squeeze the compression spring 53 to generate a reaction force. The front surface of the clamping block 54 is an arc surface, and the rear surface of the clamping block 54 is also an arc surface. When the arc surface of the clamping block 54 is squeezed, the clamping block 54 will move downward, and the clamping block 54 is inserted into the inner wall of the card slot 501. The bolt 51 will reverse due to vibration during the operation of the elevator, but the amplitude of the reverse of the bolt 51 caused by a single vibration is limited and will not cause the clamping block 54 and the card slot 501 to disengage. The outer wall of the rubber pad 55 is made of rubber. There are two sets of fixing components. One set of fixing components is located inside the connecting ring 4, and the other set of fixing components is located inside the anti-disengagement plate 1. The bolt 51 in the fixing component located inside the anti-disengagement plate 1 penetrates and is threadedly connected to the right surface of the anti-disengagement plate 1, and the rubber pad 55 is inserted into the left surface of the anti-disengagement plate 1.
[0037] Refer to Figure 1 , Figure 2 , Figure 5 , the limit block 63 penetrates and is slidably connected to the upper surface of the insertion block 61, sliding longitudinally. The right surface of the limit block 63 is an inclined surface, and the left surface of the limit block 63 is also an inclined surface. When the inclined surface of the limit block 63 is squeezed, the limit block 63 will move downward. One end of the connecting spring 62 is fixedly connected to the lower surface of the limit block 63, and the other end of the connecting spring 62 is fixedly connected to the inner wall of the bottom end of the insertion block 61. The downward moving limit block 63 will retract into the insertion block 61 and will squeeze the connecting spring 62 to generate a reaction force. The slot 601 and the limit slot 602 are communicated. The insertion block 61 is inserted into the inner wall of the slot 601. When inserting, the threaded holes on the guide wheel shaft 3 and the anti-disengagement plate 1 will be aligned, and the limit block 63 is inserted into the inner wall of the limit slot 602, which can initially fix the guide wheel shaft 3 and the anti-disengagement plate 1.
[0038] Working principle: During the installation process, first pass the guide wheel shaft 3 through the lower guide wheel 2, and then install the anti-detachment plate 1 on the left surface of the guide wheel shaft 3. The insertion block 61 in the positioning component is inserted into the slot 601 on the right surface of the anti-detachment plate 1. When the limit block 63 on the insertion block 61 encounters the slot 601, due to the design of its inclined surface, it will move downward and retract into the insertion block 61 under extrusion, and at the same time compress the connecting spring 62 to generate a reaction force. When the insertion block 61 is completely inserted into the slot 601, when the limit block 63 moves to the position of the limit slot 602, it will pop out and insert into the limit slot 602 under the action of the connecting spring 62, thereby initially fixing the guide wheel shaft 3 and the anti-detachment plate 1, and at this time the threaded holes on the guide wheel shaft 3 and the anti-detachment plate 1 can be aligned. Then, screw the bolt 51 onto the anti-detachment plate 1 to complete the fixation of the anti-detachment plate 1 and the guide wheel shaft 3. During the screwing process of the bolt 51, it will squeeze the arc surface of the clamping block 54, causing the clamping block 54 to drive the moving ring 52 to move. The moving ring 52 will squeeze the compression spring 53 to generate a reaction force. When the bolt 51 is tightened, the card slot 501 will be aligned with the clamping block 54. At this time, the reaction force of the compression spring 53 will push the moving ring 52 and the clamping block 54 to move in the reverse direction, so that the clamping block 54 is inserted into the card slot 501 to form a limit. At this time, even if the bolt 51 reverses due to vibration, when reversing, it will also squeeze the arc surface of the clamping block 54 to drive the clamping block 54 and the moving ring 52 to move and squeeze the compression spring 53 to generate a reaction force. The reaction force of the compression spring 53 will push the clamping block 54 and the moving ring 52 to move in the reverse direction, and the clamping block 54 will squeeze the card slot 501 to drive the bolt 51 to rotate and tighten, thereby achieving the effect of preventing loosening.
[0039] Similarly, when the threaded holes on the connecting ring 4 and the guide wheel shaft 3 are aligned, the bolt 51 can be tightened to fix the device. After the bolt 51 is tightened, insert the rubber pad 55 on the upper surface of the connecting ring 4 and the left surface of the anti-detachment plate 1 to block the bolt 51 to form a seal, preventing the bolt 51 from being corroded during long-term use and ensuring the stability and service life of the bolt 51.
[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
