[0026] Example 2;
[0027] like Figure 1-5As shown, the device includes a nut body 1, a pressure pad 2 at the bottom end of the nut body 1, and an anti-loosening component at the top end of the nut body 1. The anti-loosening component includes an anti-loosening sleeve 3 at the top end of the nut body 1. The anti-loosening sleeve 3 has symmetrically arranged mounting grooves 4. An adjusting cylinder 5 is provided in the mounting groove 4. The adjusting cylinder 5 is connected to the anti-loosening sleeve 3 through a fixing block 10. A pressing post 6 extending out of the mounting groove 4 is provided on one side of the adjusting cylinder 5. A push-pull rod 7 is provided on the side of the adjusting cylinder 5 away from the pressing post 6. One side of the push-pull rod 7 extends out of the mounting groove 4 and is connected to an arc-shaped clamping plate 8. The pressing post 6 is connected to the push-pull rod 7 through a linkage elastic element. An abutment pin 9 is provided on the concave surface of the arc-shaped clamping plate 8. The linkage elastic element includes a sliding plug 11 that matches the adjusting cylinder 5. A spring 12 is provided on one side of the sliding plug 11, and an inner cylinder 13 is provided on the side of the spring 12 away from the sliding plug 11. The spring 12 is connected to both the sliding plug 11 and the inner cylinder 13. The inner cylinder 13 is fixedly connected to the adjusting cylinder 5. One side of the pressing column 6 extends into the adjusting cylinder 5 and connects to the sliding plug 11. A matching sliding plug 14 is provided in the inner cylinder 13. A spring 15 connected to the inner cylinder 13 is provided on one side of the sliding plug 14. One side of the push-pull rod 7 extends into the inner cylinder 13 and connects to the sliding plug 14. Symmetrically arranged flow holes 16 are opened on the outer wall of the inner cylinder 13. A guide hole 17 that matches the outer surface of the pressing column 6 is opened on one side of the inner cylinder 13, and a guide hole 18 that matches the push-pull rod 7 is opened on the side of the inner cylinder 13 away from the guide hole 17. A sealing sleeve is provided in the first guide hole 17, and a sealing sleeve is provided in the second guide hole 18. The inner wall of the anti-loosening sleeve 3 has a storage groove 19 that matches the arc-shaped clamp 8. Several sets of abutment pins 9 are provided and evenly distributed on the concave surface of the arc-shaped clamp 8.
[0028] In practical application, to tighten the nut, first press the pressing column 6 to move the sliding plug 11 closer to the inner cylinder 13. At this time, the spring 12 is compressed. When the sliding plug 11 moves, it squeezes the gas through the flow hole 16 into the inner cylinder 13. At this time, the gas pressure in the inner cylinder 13 increases and squeezes the sliding plug 14. The sliding plug 14 begins to move and compress the spring 15. The sliding plug 14 also moves the arc-shaped clamp 8 into the receiving groove 19 through the push-pull rod 7. Then, the anti-loosening sleeve 3 is rotated to rotate the nut body 1, causing it to move on the bolt or screw. After tightening, the pressing column 6 is released. At this time, the spring 12 returns to its original position and moves the sliding plug 11 away from the inner cylinder 13. When the air pressure in cylinder 13 decreases, spring 2 15 resets and drives sliding plug 2 14 to move. Sliding plug 2 14 drives arc-shaped clamp 8 to move outside the mounting groove 4 via push-pull rod 7 and fits against the outer wall of bolt or screw. At this time, the abutment pin 9 on arc-shaped clamp 8 will insert into the thread on the outer wall of bolt or screw to limit the movement and prevent the nut body 1 from rotating. The nut can be locked by the anti-loosening component to prevent the nut from loosening and falling off the bolt or screw due to vibration, further improving its safety. The linkage elastic element can be used during the tightening of the nut. The anti-loosening component is simple and time-saving to operate through the elastic cooperation of anti-loosening sleeve, pressing column, push-pull rod, arc-shaped clamp, abutment pin and linkage elastic element.
[0029] In summary, by means of the above-mentioned technical solution of this utility model, the anti-loosening component can lock the nut, preventing the nut from loosening and falling off the bolt or screw due to vibration, thus further improving its safety. The linkage elastic element can be used during the tightening of the nut. The anti-loosening component is simple and time-saving to operate through the elastic cooperation of the anti-loosening sleeve, pressing column, push-pull rod, arc-shaped clamp, contact pin and linkage elastic element.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
