Abstract
The invention discloses rail bolts assemblies structure, including bolt and the bolt hole of fitted bolt, being provided with torsion spring in the lower end of described bolt hole, the foot of rising to the bait of torsion spring upper end is fixed on the sidewall of described bolt hole, the lower hook foot rest of torsion spring lower end is empty, and described bolt passes described torsion spring.The present invention is when bolt is screwed into, the rotation of bolt makes torsion spring have the trend of expansion, now bolt can pass through torsion spring easily, when bolt rotates along back-out direction, frictional force between torsion spring and bolt makes torsion spring be tightened, and now causes the frictional force between bolt and torsion spring to increase, and therefore bolt will be difficult to be screwed out, finally making in the case of larger vibration, bolt also will not be deviate from from bolt hole.
Description
Technical field
The present invention relates to fastener areas, more specifically, relate to fastening bolt.
Background technology
Shi Ge railway big country of China, the construction speed of railway is advanced in the world, and according in the normal railway line calculating China
The fastening bolt being fastened on sleeper by rail just has more than 1,000,000,000, and China comes into the high ferro epoch particularly now, fire
The speed of service of car is increasingly faster, owing to long-term is run at high speed, causes rail high vibration frequently, and time one length may
Causing part rail fastening bolt to get loose, will have a strong impact on railway operation safety, country is for traffic safety, railway for many years
Department takes substantial amounts of manpower and materials and has sent substantial amounts of railway patrolman that rail is fastened situation on china railway line
Manually investigating, but face the high ferro epoch of today, the efficiency of artificial investigation is the oldest more cannot meet existing ferrum
Road demand for security.
Summary of the invention
For the deficiencies in the prior art, the invention provides rail bolts assemblies structure.
The present invention is achieved through the following technical solutions: rail bolts assemblies structure, including bolt and fitted bolt
Bolt hole, be provided with torsion spring in the lower end of described bolt hole, the foot of rising to the bait of torsion spring upper end is fixed on the sidewall of described bolt hole,
The lower hook foot rest of torsion spring lower end is empty, and described bolt passes described torsion spring.
In technique scheme, described bolt hole includes the first hole and the second hole being interconnected, and the aperture in the second hole is big
In the first hole, described torsion spring is positioned at described second hole.
In technique scheme, described bolt lower end is provided with chamfering.
There is advantages that the present invention when bolt is screwed into, the rotation of bolt makes torsion spring have expansion
Trend, now bolt can pass through torsion spring easily, bolt along screw out direction rotate time, rubbing between torsion spring and bolt
Wiping power makes torsion spring be tightened, and now causes the frictional force between bolt and torsion spring to increase, and therefore bolt will be difficult to be screwed out, finally
Making in the case of larger vibration, bolt also will not be deviate from from bolt hole.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the bolt schematic diagram of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings: see Fig. 1 to Fig. 2, rail
Using bolts assemblies structure, including the bolt hole 2 of bolt 1 and fitted bolt, described bolt 1 lower end is provided with chamfering 10.Described
The lower end of bolt hole 2 is provided with torsion spring 3, and the foot 30 of rising to the bait of torsion spring 3 upper end is fixed on the sidewall of described bolt hole 2, torsion spring 3 lower end
Lower hook foot 31 make somebody a mere figurehead, described bolt 1 is through described torsion spring 3.
Described bolt hole 2 includes the first hole 20 and the second hole 21 being interconnected, and the aperture in the second hole 21 is more than the first hole
20, described torsion spring 3 is positioned at described second hole 21.
The present invention is when bolt is screwed into, and the rotation of bolt makes torsion spring have the trend of expansion, and now bolt can facilitate
By torsion spring, bolt along screw out direction rotate time, the frictional force between torsion spring and bolt makes torsion spring be tightened, now
Causing the frictional force between bolt and torsion spring to increase, therefore bolt will be difficult to be screwed out, and finally make in the case of larger vibration, spiral shell
Bolt also will not be deviate from from bolt hole.
