Problems solved by technology
[0004] However, in some occasions and situations, these anti-loosening methods are not applicable
For example, when the bolt is directly screwed into the threaded hole and used as a screw, the mechanical anti-loosening method cannot be used, and the permanent anti-loosening method cannot be disassembled, and only frictional anti-loosening can be used.
However, among the three anti-loosening methods, frictional anti-loosening has the worst stability.

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the drawings and embodiments. However, the use and purpose of these exemplary embodiments are only to illustrate the present invention, and do not constitute any limitation to the actual protection scope of the present invention in any form, let alone limit the protection scope of the present invention.
[0022] Such as figure 1 As shown, the present invention provides an anti-dropping bolt. The anti-dropping bolt mainly includes an outer hexagonal bolt body. The outer hexagonal bolt body has a thread extension 1 and a hexagonal head end 2, and a hexagonal head end 2. A first hydraulic channel 3 extending in the axial direction of the hexagon head end 2 is provided, the first hydraulic channel 3 is located at one side of the thread extension 1, and the first hydraulic channel 3 is located at the end of the thread extension 1 side A first plunger 6 is provided. The first plunger 6 extends out of the h...

The invention discloses an anti-dropping bolt, and belongs to the technical field of fasteners. The anti-dropping bolt comprises a threaded extending portion and a hexagonal head which are sequentially arranged. A first hydraulic channel is arranged at the hexagonal head, a first plunger is arranged in the first hydraulic channel and extends out of the hexagonal head, the threaded extending portion is provided with a second hydraulic channel, the second hydraulic channel extends to the hexagonal head and is communicated with the first hydraulic channel via a connecting channel, an open slot which radially extends along the threaded extending portion is formed in the end, which is far away from the hexagonal head, of the threaded extending portion, an end of the second hydraulic channel is communicated with the open slot, a second plunger is arranged in the second hydraulic channel and is positioned at an end of the open slot, and the second hydraulic channel, the connecting channel and the first hydraulic channel which are positioned between the first plunger and the second plunger are filled with hydraulic oil; a one-way structure is arranged in the connecting channel, and the hydraulic oil can flow from the first hydraulic channel to the second hydraulic channel in a single direction under the effect of the one-way structure. The anti-dropping bolt has the advantages of stable performance and good anti-dropping effect.
Description
Technical field [0001] The invention relates to a bolt, in particular to an anti-falling bolt, and belongs to the technical field of fasteners. Background technique [0002] In the field of machinery manufacturing, there are three commonly used methods to prevent bolts from loosening: friction, mechanical, and permanent. [0003] Among them, mechanical anti-loose and friction anti-loose are called detachable anti-loose, and permanent anti-loose is called non-detachable anti-loose. Commonly used permanent anti-loosening include: spot welding, riveting, bonding, etc. This method mostly destroys threaded fasteners during disassembly and cannot be reused; common frictional anti-loosening methods include: using gaskets, self-locking nuts and double Nuts, etc.; common mechanical anti-loosening methods include the use of split pins, stop washers, and string wire ropes. Among these anti-loose methods, mechanical anti-loose is widely used because of its reliable performance and convenient...
