Abstract
The utility model discloses a can avoid long-term vibration to cause the nut not hard up, can guarantee firm in connection's bolt antivibration connection structure. The bolt anti-vibration connecting structure comprises a bolt and a nut matched with the bolt; one connecting end surface of the nut is provided with a chamfer surface; one end of the bolt penetrates through the connecting piece and is provided with a nut; the chamfered surface of the nut contacts the connecting member. Adopt this bolt antivibration connection structure can avoid the vibration to make the nut not hard up, can improve the fastness of connecting.
Description
Technical Field
The utility model relates to a connection structure of bolt, especially a bolt antivibration connection structure.
Background
It is well known that: when the bolt and the nut are used for connecting the objects, the nut needs to be screwed on the connected objects. Thereby playing a role of fastening. Two faces of a traditional nut are planes, so that after the nut is screwed down, the nut is easy to loosen and drop when frequent vibration occurs on a connecting piece, and therefore insecure connection is caused, and safety accidents are easy to occur.
The existing solution is to add a gasket and an elastic gasket between the connected object and the nut, so as to avoid the above situation, but the elastic gasket has a poor anti-vibration effect on the bolt under the condition of frequent vibration.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a can avoid long-term vibration to cause the nut not hard up is provided, firm in connection's bolt antivibration connection structure can be guaranteed.
The utility model provides a technical scheme that its technical problem adopted is: the bolt anti-vibration connecting structure comprises a bolt and a nut matched with the bolt; one connecting end surface of the nut is provided with a chamfer surface;
one end of the bolt penetrates through the connecting piece and is provided with a nut; the chamfered surface of the nut contacts the connecting member.
Preferably, the included angle α between the chamfer and the connecting end surface is 3-10 degrees.
Furthermore, two second inclined planes which are symmetrically distributed about the vertical middle section of the nut are arranged on the inclined cutting plane of the nut.
Furthermore, a nut rotating block is arranged on one connecting surface of the nut; a connector is arranged between the nut rotating block and the nut; one side of the connecting body is provided with a notch.
The utility model has the advantages that: bolt antivibration connection structure owing to be provided with the scarf on a connection terminal surface of nut, consequently after screwing up the nut, resume again and apply the tightening force, the nut can be to a direction slope this moment to can cause the internal thread damage of nut, thereby make the nut card die on the bolt, thereby can avoid the vibration to make the nut not hard up, can improve the fastness of connection.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 6, the bolt vibration-proof connection structure of the present invention includes a bolt 1 and a nut 2 matched with the bolt; a chamfer 3 is arranged on one connecting end surface of the nut 2;
one end of the bolt 1 penetrates through the connecting piece and is provided with a nut 2; the chamfered surface 3 of the nut 2 is in contact with the connecting member.
In the application process, as shown in fig. 1, one end of the bolt 1 sequentially passes through the first connecting piece 4 and the second connecting piece 5; the nut 2 is fitted to one end of the bolt 1 and is located below the second connecting member 5, and the chamfered surface 3 of the nut 2 is in contact with the bottom surface of the second connecting member 5. Additional torque is then applied to continue turning the nut 2 until the nut 2 cannot be turned. One connecting end surface of the nut 2 is provided with a chamfer surface 3; therefore, after the nut is screwed down, the screwing force is continuously applied, the nut can incline to one direction at the moment, the internal thread of the nut is damaged, the nut is clamped on the bolt, the nut is prevented from vibrating and loosening, and the connection firmness can be improved.
In order to reduce the additionally applied torque force for destroying the internal thread of the nut, the included angle α between the chamfer 3 and the connecting end face is 3-10 degrees.
In order to ensure that the internal thread of the nut 2 can be broken so that the nut 2 is locked on the bolt 1, two second inclined planes 7 are further arranged on the inclined plane 3 of the nut 2 and are symmetrically distributed about the vertical middle section of the nut.
In order to facilitate the screwing of the nut and avoid the damage of the nut 2 under the action of extra torque force, so that the connection cannot be realized, and furthermore, a nut rotating block 6 is arranged on one connection surface of the nut 2; a connector 9 is arranged between the nut rotating block 6 and the nut 2; one side of the connecting body 9 is provided with a notch 8.
By providing the nut rotating block 6, even if the nut 2 is broken and chipped, the connection of the bolt 1 can be achieved by the nut rotating block 6.
