Model airplane shock absorber screw

The damping is composed of screw bolts; and the rubber column, the screw is larger than the diameter of the screw head screw, the screw head on into the ends of rubber column in the end face of the head of the screw thread surface and the rubber column near the flat or slightly convex, coaxial columns at both ends of the rubber screw. The utility model has the advantages that the equivalent damping pad and bolt together, without increasing the number of parts; the rubber column can be sufficiently large or thick, strengthens the instruments, the axial and radial damping effect; and let the soft rubber column, can reduce the bolt installation accuracy requirements; simple structure and can be widely used for connecting the supporting instruments.    

  1, a damping bolt, comprising a screw, a rubber column, the screw is larger than the diameter of the screw head, which is characterized in that the screw (1) screw head (2) at both ends of the rubber column (3) embedded in the screw head (2) near the end surface of the rubber thread column (3) of the end flat or slightly convex, rubber column (3) at both ends of the screw (1) coaxial
