Abstract
A bolt fastening mechanism with one shot adopts a bolt to fasten a piece requiring being fastened to a fixing piece. The uncovered hole of the piece requiring being fastened is firstly provided with an enlarged diameter, and then installed with a tooth-like sleeve with a saw shaped internal wall. The tooth-like sleeve is in stationary fit with the uncovered hole. The uncovered section of the bolt is processed with 1 to 3 agnails, which face in a different direction from the screwing direction and rely on its own elasticity to be clamped into the tooth groove of the tooth-like sleeve wherein the bolt can only screw but can not be pulled out. With such a structure, the bolt fastening mechanism can be applied on occasions where repetitive dismantling and welding connections are not applicable and with only one shot, a piece requiring being fastened can be firmly fastened to a fixing piece, with the result that even with a wrench, the already fastened piece can not be detached away from the fixing piece.
Description
Technical field
The utility model relates to bolt fastening structure.
Background technique
It is the most general a kind of mechanical connection manner that bolt connects.This linkage structure is to be processed with screw thread in the front portion of bolt, is processed with screw on fixture, is added with the screw thread of cooperation on fixed block, screws power by nut, and two parts are fixed together.In order to prevent the loosening spring pad that generally below nut, adds.This Placement can repeated removal.
But the object that has does not need to dismantle again after connecting, and belongs to permanent connection.Wait other Placements but be unsuitable for welding.So be sought after a kind of new disposable bolt fastening structure.
Summary of the invention
The new purpose of this practicality is a kind of disposable bolt fastening structure of design.
A kind of disposable bolt fastening structure, it is with bolt fixture to be connected on the fixed block, it is characterized in that, the naked bore dia overstriking of fixture, after the overstriking of naked hole an inwall being installed is jagged facing, facing and the stationary fit of naked hole; The nude section of bolt is processed with 1-3 hangnail, hangnail towards with to screw direction opposite and lean on self elasticity to be stuck in the teeth groove of facing.Facing can adopt interference fit with cooperating also of naked hole.
This linkage structure, having solved does not need repeated removal to be unsuitable for welding the occasion that waits other Placements again, after the disposable connection, does not have any becoming flexible, and can't dismantle with the spanner common tool.
For example road manhole, Theft-proof cabinet etc. are easy to be dismantled by the human spanner as connecting with plain bolt, adopt linkage structure of the present utility model can solve antitheft problem, unless with improper means it is destroyed.
Description of drawings
Fig. 1 is embodiment's a plan view.
Among the figure: 1-bolt, 2-fixture, 3-flexuose facing, 4-fixed block, 5-hangnail.
Embodiment: as shown in Figure 1, linkage structure of the present utility model is with bolt 1 fixture 2 to be connected on the fixed block 4, the wherein naked bore dia overstriking of fixture 2 is installed a flexuose facing 3, flexuose facing 3 and stationary fit of naked hole or interference fit after the overstriking of naked hole; The nude section of bolt 1 is processed with 1-3 hangnail 5, hangnail 5 towards with to screw direction opposite and lean on self elasticity to be stuck in the teeth groove of facing, bolt 1 can only precession and can not be poured out.
Claims (2)
1. disposable bolt fastening structure, it is with bolt fixture to be connected on the fixed block, it is characterized in that, the naked bore dia overstriking of fixture, after the overstriking of naked hole an inwall being installed is jagged facing, facing and the stationary fit of naked hole; The nude section of bolt is processed with 1-3 hangnail, hangnail towards with to screw direction opposite and lean on self elasticity to be stuck in the teeth groove of facing.
