Description

Technical Field

[0001] The utility model relates to an anti-dropping and anti-vibration bolt, belonging to the technical field of bolts. Background Art

[0002] A bolt is a mechanical part, consisting of a head and a screw (a cylinder with external threads). It is a cylindrical threaded fastener that is matched with a nut. The bolt and the nut are used to fasten two parts with through holes. This type of connection is called a bolt connection. The nut can be unscrewed from the bolt, and the two parts can be separated, so the bolt connection is a detachable connection.

[0003] There are still some problems in the use of existing anti-falling and anti-vibration bolts. For example, after long-term use, the threads on the outside of the bolt and the threads inside the connecting piece will wear, causing the bolt to loosen and fall off during installation. At the same time, the top of the bolt is located on the outside of the connecting piece. When it is hit by other external objects, it will generate a large impact force, and the bolt itself does not have an anti-vibration function. Utility Model Content

[0007] Furthermore, an L-shaped plate is fixedly connected to the outer side of the rotating cover, a connecting rod is fixedly connected to the bottom of the L-shaped plate, and an elastic airbag is fixedly connected to the bottom of the connecting rod.

[0008] Furthermore, the bolt body is threadedly connected between the No. 1 connecting piece and the No. 2 connecting piece, and the rotating cover is located above the No. 1 connecting piece.

[0009] Furthermore, the lifting rod crosses the interior of the moving hole, the extrusion cover is located outside the rotating cover, and the top of the return spring is fixedly connected to the bottom of the bolt body.

[0010] Furthermore, the hidden grooves are symmetrically distributed inside the connecting plate, and the number of the limiting plates is the same as the number of the pulling blocks.

[0011] Furthermore, the L-shaped plates are symmetrically distributed on the outside of the rotating cover, and the L-shaped plates are located on the outside of the top of the No. 1 connecting piece.

[0012] Furthermore, the number of the connecting rods is the same as that of the elastic airbags, and the bottom of the elastic airbag is movably connected to the top of the No. 1 connecting piece.

When the connection is completed, the extrusion cover is pressed to drive the lifting rod to move inside the moving hole, so that the lifting rod drives the connecting plate at its bottom to move to the outside of the bottom of the No. 2 connecting piece. At this time, the limit plate is driven out of the hidden groove inside the connecting plate by the pulling block, so that the limit plates are symmetrically distributed on the outside of the connecting plate. At this time, the extrusion cover is released, and the lifting rod moves upward under the action of the reset spring. At this time, the connecting plate and the outer limit plate will be located on the outside of the No. 2 connecting piece, thereby reinforcing the bolt body and achieving the effect of preventing it from falling off.

[0015] (ii) The utility model provides a bolt body, and a rotating cover is fixedly connected to the top of the bolt body. When the bolt body is installed, the rotating cover is located on the top outer side of the No. 1 connecting piece. An L-shaped plate is fixedly connected to the outer side of the rotating cover.
