Abstract
The utility model discloses a vibration damping bolt. The utility model comprises a bolt, a but and a cushion ring; besides, the utility model also comprises a damping vibration damping sleeve pipe which is sheathed with the outer side of the bolt. The utility model has the advantages that the addition of the damping vibration damping cushion ring and the damping vibration damping sleeve pipe effectively lowers noise generated when the nut and the bolt contact a rigid body; the utility model is simple in structure and in usage in construction.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of vibration damping bolt.
Background technique
Noise and vibration have very confidential relation, have many noises to bring out generation by vibration.Vibration is propagated by rigid body especially metal, outside radiated noise in propagation process, thus transmit noise.The major technique measure of control vibration noise is a damping isolation.For using being fastenedly connected of bolt, generally take below nut, to place compression spring or other damping washers in the existing damping vibration attenuation technology, its major defect is the transaudient problem of rigid body that does not solve between bolt and the fastening piece, thereby cause the vibration and noise reducing decreased performance, can not satisfy requirement of engineering.
The model utility content
The purpose of this utility model is, overcomes deficiency of the prior art, provides a kind of novel vibration damping bolt, to satisfy the needs in the engineering.
For achieving the above object, the vibration damping bolt that the utility model provides comprises bolt, nut, packing ring; Also comprise the damping vibration attenuation sleeve pipe, described damping vibration attenuation sleeve pipe is placed in the bolt outside.
Further, the thickness of pipe wall of described damping vibration attenuation sleeve pipe is between 1 to 5 millimeter.
Further, the damping vibration attenuation packing ring of described packing ring for adopting rubber to make, thickness is between 1 to 5 millimeter.
Good result of the present utility model is: the increase of damping vibration attenuation packing ring and damping vibration attenuation sleeve pipe, effectively reduce nut and bolt contact with rigid body vibrate the noise that is produced; Secondly, the utility model is simple in structure, uses simple, convenient in construction.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is a user mode schematic representation of the present utility model.
Embodiment
With reference to Fig. 1, the vibration damping bolt in the present embodiment comprises 2, two damping vibration attenuation packing rings 4 of 1, two nut of a stud bolt and a damping vibration attenuation sleeve pipe 3; Damping vibration attenuation sleeve pipe 3 is placed in the surface of bolt 1 intermediate section, and is transition fit, and wherein, damping vibration attenuation sleeve pipe 3 adopts the vibration isolation rubber with damping vibration attenuation performance and mechanical strength to make, and has all lengths specification.
The material of two damping vibration attenuation packing rings 4 also adopts the vibration isolation rubber with damping vibration attenuation performance and mechanical strength, and packing ring center hole and cylindrical have various sizes, can match with the stud bolt 1 of various sizes.
With reference to Fig. 2, porose in the middle of the member 5, stud bolt 1 is a transition fit with damping vibration attenuation sleeve pipe 3, and the length of damping vibration attenuation sleeve pipe 3 preferably is slightly larger than the member section width, and damping vibration attenuation packing ring 4 lays respectively between nut 2 and the component sidewall.
Bolt in the utility model can also be the plain bolt of strap bolt head.
Claims (5)
1. a vibration damping bolt comprises bolt, nut, packing ring; It is characterized in that, also comprise the damping vibration attenuation sleeve pipe, described damping vibration attenuation sleeve pipe is placed in the bolt outside.
2. vibration damping bolt according to claim 1, wherein, described packing ring is the damping vibration attenuation packing ring that rubber is made, thickness is between 1 to 5 millimeter.
