Description
Technical field
The utility model relates to a kind of nut that carries pad.
Background technique
At present; existing and screw, bolt etc. are used; the nut and the pad that fix union piece are the split setting, and pad is used for increasing the area of contact of nut and fixture, thereby reduces pressure; reach the purpose of protection part, locking part; but vibrations or other reason owing to part make nut and pad still can become flexible; can not well part be fixed, sometimes owing to these reasons cause tremendous loss.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of energy shockproof, the locking nut that carries pad.
The technical solution of the utility model: a kind of nut that carries pad, include the nut body that is provided with tapped hole, described nut body lower end is provided with a pad, pad is provided with a through hole, described pad and nut body rotation are connected, the upper edge, upper-end surface of the described pad circumferentially some cross sections of distribution is the otch of obtuse triangle, the obtuse angle of described otch is positioned at all the other two acute angles belows, described otch along the second limit of nut body screw-in direction with respect to the tilt angle of vertical direction less than its along article one limit of nut body screw-in direction the tilt angle with respect to vertical direction, described nut body lower end surface is provided with the latch that is complementary with described otch.
Adopt technique scheme, the pad lower end surface is provided with some sawtooth, at the nut and the screw that this are carried pad, when bolt connects, make pad and fixture surface fit the whole rotation of this nut earlier, again nut body is rotated, because the pad upper-end surface is provided with otch, the nut body lower end surface is provided with the latch that is complementary with otch, and cut-out section be obtuse triangle and otch along the second limit of nut body screw-in direction with respect to the tilt angle of vertical direction less than its along article one limit of nut body screw-in direction the tilt angle with respect to vertical direction, when nut body rotates to a certain degree, the latch of nut body lower end surface can block mutually with the otch of pad upper-end surface and join, make nut body can not continue rotation, can reach shockproof well, anti-loosing effect.
Further improvement of the utility model: described pad lower end surface is the some sawtooth of distribution circumferentially.Adopt above-mentioned further improvement, during with the whole rotation of nut, the sawtooth of pad lower end surface can be inserted in the fixture, make nut fixedly connected with screw, bolt etc. shockproof, anti-loosing effect is better.
The utility model further improves: described pad upper-end surface is protruding arc surfaced.Adopt above-mentioned further improvement, when nut body can not continue to rotate, because the pad upper-end surface is set to protruding arc surfaced, can produce certain elasticity, like this, the latch of the otch of pad upper-end surface and nut body lower end surface can block join tighter, and is shockproof, anti-loosing effect is better.
The utility model further improves again: described nut body lower end surface circumferentially is extended with annular boss downwards along its tapped hole, be provided with the internal thread that screw thread is complementary in the tapped hole with described nut body in the described annular boss endoporus, the external diameter of described annular boss and the through-hole diameter of described pad are complementary, described annular boss lower end surface is outward extended with back-up ring, and described through hole is set in and constitutes described pad on the annular boss between described nut body lower end surface and the back-up ring and rotate with nut body and be connected.Adopt above-mentioned further improvement again, simple in structure, easy to process, pad is rotatably connected reliably with nut body.

Embodiment
Extremely shown in Figure 10 as Fig. 1, a kind of nut that carries pad 2, include the nut body 1 that is provided with tapped hole 11, described nut body 1 lower end is provided with a pad 2, pad 2 is provided with a through hole 21, described pad 2 is connected with nut body 1 rotation, the upper edge, upper-end surface of the described pad 2 circumferentially some cross sections of distribution is the otch 22 of obtuse triangle, the obtuse angle of described otch 22 is positioned at all the other two acute angles belows, described otch 22 along the second limit 221 of nut body 1 screw-in direction with respect to the tilt angle of vertical direction less than its along article one limit 222 of nut body 1 screw-in direction the tilt angle with respect to vertical direction, described nut body 1 lower end surface is provided with the latch 12 that is complementary with described otch 22.The latch 12 and the otch 22 of described nut body 1 lower end surface is complementary for when nut body 1 rotates, this latch 12 does not influence its rotation with otch 22, when rotating to a certain degree, described latch 12 constitutes card with otch 22 joins, and stops self rotating of nut body 1.In this specific embodiment, described latch 12 sectional shapes also are obtuse triangle, the obtuse angle is positioned at the below of all the other two acute angles, described latch 12 along the second limit 121 of nut body 1 screw-in direction with respect to the tilt angle of vertical direction less than its along article one limit 122 of nut body 1 screw-in direction the tilt angle with respect to vertical direction, described latch 12 with otch 22 respectively along described nut body 1 lower end surface, pad 2 upper-end surface continuous distributed.Certain described latch 12 also can exchange with otch 22, promptly on pad 2 upper-end surfaces latch 12 is set, and on nut body 1 lower end surface otch 22 is set.
Join with the card of described nut body 1 lower end surface latch 12 in order further to improve described pad 2 upper-end surface otch 22, in this specific embodiment, described pad 2 upper-end surfaces are protruding arc surfaced.
In the utility model, described nut body 1 lower end surface circumferentially is extended with annular boss 13 downwards along its tapped hole 11, be provided with the internal thread that screw thread is complementary in the tapped hole 11 with described nut body 1 in described annular boss 13 endoporus, through hole 21 diameters of the external diameter of described annular boss 13 and described pad 2 are complementary, described annular boss 13 lower end surfaces are outward extended with back-up ring 14, and described through hole 21 is set in and constitutes described pad 2 on the annular boss 13 between described nut body 1 lower end surface and the back-up ring 14 and be connected with nut body 1 rotation.Described annular boss 13 external diameters and through hole 21 diameters are complementary and are described annular boss 13 and through hole 21 Spielpassung, and pad 2 can be around annular boss 13 rotations.To be complementary for linking and pitch, rotation direction etc. are identical mutually be that screw thread and same screw, bolt match in the tapped hole 11 of annular boss 13 internal threads and nut body 1 to screw thread in the tapped hole 11 of described annular boss 13 internal threads and described nut body 1.
