[0025] Refer to Figures 1-4 As shown, the present utility model provides a technical solution: an anti-vibration and anti-loosening bolt structure, including a regular hexagonal prism block 1, a screw rod 2 fixedly connected to the surface of the regular hexagonal prism block 1, a nut 3 threadedly connected to the side wall of the screw rod 2, and a gasket 4 sleeved on the outside of the screw rod 2.
[0026] Next, specifically describe its overall specific settings and functions.
[0027] In this implementation: a card slot 6 is opened on the side wall of the screw rod 2, six rectangular blocks 13 are evenly and fixedly connected to the surface of the nut 3, and a card frame 12 is slidably connected inside the rectangular block 13. One of the card frames 12 on the nut 3 will be inserted into the inside of the card slot 6, so as to realize the locking work of the nut 3.
[0028] Six baffle plates 15 are evenly and fixedly connected to the surface of the nut 3, two elastic sheets 14 are fixedly connected to the surface of the card frame 12, and the side of the elastic sheet 14 away from the card frame 12 is an arc structure. The card frame 12 will be inserted into the inside of the card slot 6 under the elastic force of the elastic sheet 14 on the baffle plate 15. Two slide bars 7 are slidably connected inside the screw rod 2, both of the two slide bars 7 are located inside the card slot 6, and a support bar 5 is fixedly connected to the end sides of the two slide bars 7, and the support bar 5 is located inside the card slot 6. The sliding of the slide bar 7 inside the screw rod 2 plays a role in restricting the moving direction of the support bar 5.
[0029] Specifically, a limit bar 8 is slidably connected inside the screw rod 2, the other end of the limit bar 8 is fixedly connected to a pressure plate 9, a support block 11 is fixedly connected to the surface of the pressure plate 9, and one side of the support block 11 is provided with an inclined surface. The pressure plate 9 will drive the support block 11 to be inserted into the inside of the card slot 6. At this time, relative movement will occur between the inclined surface of the pressure plate 9 and the support bar 5, so as to realize the extrusion work on the pressure bar. An elastic pad 10 is adhesively bonded to the surface of the pressure plate 9. The elastic pad 10 on the pressure plate 9 facilitates the hand to apply pressure to the pressure plate 9. Anti-slip lines are provided on the surface of the elastic pad 10. The setting of the anti-slip lines on the elastic pad 10 improves the stability of applying pressure to the pressure plate 9.
[0030] Working principle: During the actual use of the bolt, when it is necessary to screw the nut 3 onto the outside of the screw rod 2, first press the pressure plate 9. The elastic pad 10 on the pressure plate 9 facilitates the hand to apply pressure to the pressure plate 9. The anti-slip pattern on the elastic pad 10 improves the stability of applying pressure to the pressure plate 9. The limiting rod 8 on the pressure plate 9 slides inside the screw rod 2 to play a role in restricting the moving direction of the pressure plate 9. The pressure plate 9 drives the support block 11 to insert into the inside of the card slot 6. At this time, relative movement occurs between the inclined surface of the pressure plate 9 and the support bar 5, so as to realize the extrusion work on the pressure bar. After the pressure bar is extruded to the position of the arc surface of the screw rod 2, the nut 3 can be rotated to the outside of the screw rod 2. The sliding rod 7 slides inside the screw rod 2 to play a role in restricting the moving direction of the support bar 5. The pressure bar is filled at the edge of the card slot 6, which facilitates the rotation of the nut 3 on the screw rod 2. At this time, the rotation of the nut 3 on the screw rod 2 can be realized. When the nut 3 rotates to the position where the device is tightened, release the pressure plate 9. One of the card frames 12 on the nut 3 is inserted into the inside of the card slot 6 under the elastic force of the elastic piece 14 on the baffle 15, so as to realize the locking work on the nut 3, avoiding the phenomenon of torsion between the nut 3 and the screw rod 2, and further avoiding the phenomenon that the nut 3 is easily loosened from the screw rod 2 during vibration. By setting the above structure, the locking work between the screw rod 2 and the nut 3 is facilitated, and the phenomenon of vibration loosening of the bolt during use is avoided, which improves the stability of using the bolt structure to a certain extent.
