Abstract
The invention relates to a primary and secondary locking bolt, which comprises a nut 3, an inner bolt 1 and outer bolt 2, wherein the center of outer bolt 2 has post hole whose inner wall has inner screw; the lower end of hole is reduced; the inner screw is in snail shape. The invention can prevent vibration with better locking property.
Description
Technical field
The present invention relates to a kind of bolt.
Background technique
Existing clamping bolt can not be shockproof, and the vibrations back is loosening easily, causes very big loss.
Summary of the invention
Purpose of the present invention is exactly the primary and secondary lock bolt that provides a kind of energy shockproof for overcoming the above problems.
Technological scheme of the present invention is achieved like this: a primary and secondary lock bolt, comprise nut, and be characterized in: it also comprises inner bolt 1 and outer bolt 2, the center portion of outer bolt is provided with cylindrical hole, the hole inwall is provided with internal thread, and the lower end in hole is gradually thin, and inner bolt 1 is spike.
Because bolt of the present invention is made up of two-part, inner bolt screws in the center hole of outer bolt, the locking nut by the tube wall of extruding outer bolt.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1---inner bolt 2---outer bolt 3---nut 4---inner bolt conical head among the figure
5---the outer bolt under shed
Embodiment
From Fig. 1 as seen, the present invention includes three parts: nut 3, inner bolt 1.Outer bolt 2, the center portion of outer bolt 2 is provided with cylindrical hole, and the wall in hole is provided with internal thread, and the outer bolt under shed is with gradually thin.Inner bolt 1 is spike, and the lower end of inner bolt is an inner bolt conical head 4.Earlier with outer bolt 2 precession nuts 3, in the outer bolt 2 that inner bolt 1 screw-in plastic material is surrounded, reach the locking purpose again during use by the under shed that pushes outer bolt.
