Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
A fastening nut, as shown in fig. 1 and 2, comprises a hexagonal nut body 1 and a metal washer 2 integrally connected to one side of the nut body 1, wherein a threaded hole 5 is arranged in the middle of the nut body 1. The bottom of the upper metal gasket 2 is provided with a rubber gasket 4 and a lower metal gasket 3, and the rubber gasket 4 is positioned between the upper metal gasket 2 and the lower metal gasket 3. The upper metal gasket 2, the lower metal gasket 3 and the rubber gasket 4 are coaxially arranged and have equal sizes. The lateral wall of going up metal washer 2 runs through three locating hole 11 along 2 circumferencial direction align array of last metal washer, and three locating hole 11 all is radial setting and intercommunication each other with screw hole 5. All slide in the three locating hole 11 and be provided with locating piece 9 and every locating piece 9 all sets up to the forked tail strip, and locating hole 11 sets up to the forked tail trough-like to cooperation effect through forked tail strip and dovetail improves both. Wherein, each positioning hole 11 is penetrated through the lower end surface of the upper metal gasket 2.
As shown in fig. 2 and 3, three through holes 10 penetrate through the lower metal gasket 3 and the rubber gasket 4, positioning rods 7 penetrate through the three through holes 10, and the positioning rods 7 sequentially penetrate through the lower metal gasket 3 and the rubber gasket 4 and are located right below the corresponding positioning holes 11. The top of each locating lever 7 is provided with a first guiding inclined plane 8, and under the initial state, the first guiding inclined plane 8 is not in contact with the locating block 9. In the locking and tightening process of the nut body 1, the rubber washer 4 is compressed to deform, so that the positioning rod 7 extends into the positioning hole 11 and abuts against the positioning block 9, the positioning block 9 is pushed towards the threaded hole 5 under the guiding effect of the first guiding inclined plane 8, and the three positioning blocks 9 abut against corresponding threaded rods, so that the locking effect is achieved.
For being convenient for first direction inclined plane 8 to promote locating piece 9 further, locating piece 9 is kept away from screw hole 5 one end and is provided with second direction inclined plane 12, and first direction inclined plane 8 and second direction inclined plane 12 can laminate each other and form the cooperation, have improved the direction effect. And locating lever 7 all is the square bar setting, and the opening shape and the locating lever 7 phase-match of through-hole 10 to guarantee that first direction inclined plane 8 and second direction inclined plane 12 can form stable cooperation state.
Three standing groove 6 that covers corresponding through-hole 10 open-ended respectively is seted up to the bottom surface of lower metal washer 3, and the equal body coupling in bottom of locating lever 7 has spacing cap 13, and every spacing cap 13 all can imbed in standing groove 6 just, and every spacing cap 13 all is in standing groove 6 through sticky mode fixed connection.
In order to guarantee that the positioning rod 7 can stretch into the corresponding positioning hole 11 when the rubber gasket 4 is compressed, the upper metal gasket 2 and the rubber gasket 4 jointly penetrate through three fixing holes 14 which are uniformly arranged along the circumferential direction of the upper metal gasket, the three fixing rods 15 which can respectively penetrate into the corresponding fixing holes 14 are fixedly connected with the upper end face of the lower metal gasket 3, and each fixing hole 14 sequentially penetrates through the rubber gasket 4 and the upper metal gasket 2.
Preferably, the lower end surface of the lower metal gasket 3 is provided with a plurality of anti-slip threads to further improve the anti-back effect.
The specific operation flow of this embodiment is as follows: the three positioning blocks 9 are respectively inserted into the three positioning holes 11, the positioning rod 7 is inserted into the through hole 10 from the bottom end of the lower metal washer 3, and the screw cap is screwed into the corresponding screw rod. At this moment, the positioning holes 11 and the positioning blocks 9 are not in contact, and as the nut body 1 is gradually screwed down, the rubber gasket 4 has elasticity and generates certain deformation, so that the top ends of the three positioning rods 7 extend into the corresponding positioning holes 11, the first guide inclined surfaces 8 of the positioning screws 7 and the second guide inclined surfaces 12 of the positioning blocks 9 are in mutual contact and push the positioning blocks 9 to slide inwards, and then the positioning screws are tightly abutted to form locking, so that the effects of preventing loosening and stopping are achieved.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
