Abstract
A kind of screw thread self-locking locking device based on inclination angle inclined-plane, it include: the nut on inclined-plane one with angle and the gasket on inclined-plane with angle two, during tightening nut and gasket, the point or inclination angle inclined-plane two that the inclination angle inclined-plane one and gasket first contact are fulcrum with the point that nut first contacts, moment of flexure is generated at the form of thread of the nut and bolt, the form of thread of the nut and bolt generates flexible deformation.Its principle is simple, simple in construction, easy to disassemble and assemble, implementation can be directly improved on plain nut, at low cost, maintainability is good.
Description
Technical field
The utility model relates to be threadedly coupled field, the in particular to locking dress of a kind of screw thread self-locking based on inclination angle inclined-plane
It sets.
Background technique
Be bolted due to its easily specially tear open conveniently, feature convenient for safeguarding be widely used in each field.However, by
In the difference of use environment, in vibration, corrosion and repeatedly in the practice of fatigue stress, it is threadedly coupled the loose phenomenon of appearance
Especially frequently, great security hidden trouble is brought.Therefore as why not increased structure design difficulty, not increasing use cost and not
Under the limited conditions for reducing maintainability, the difficult point that the self-lock ability of threaded connection is research how is improved.The present invention is based on inclination angles
The principle that inclined-plane increases moment of friction considers, has invented a kind of screw thread self-locking anti-loose method based on inclination angle inclined-plane, has structure
Simply, using, distinguishing features such as convenient for disassembly and assembly, at low cost, it is suitable for all kinds of threaded connections.
Utility model content
For above-mentioned deficiency in the prior art, it is anti-that the utility model provides a kind of screw thread self-locking based on inclination angle inclined-plane
Loose device, principle is simple, simple in construction, easy to disassemble and assemble, and implementation can be directly improved on plain nut, at low cost, dimension
Shield property is good.
In order to reach above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
A kind of screw thread self-locking locking device based on inclination angle inclined-plane, comprising: the nut on inclined-plane one with angle and it is with angle tiltedly
The gasket in face two, during tightening nut and gasket, point or inclination angle inclined-plane that the inclination angle inclined-plane one is first contacted with gasket
2 points first contacted with nut are fulcrum, generate moment of flexure at the form of thread of the nut and bolt, the nut and bolt
Form of thread generates flexible deformation.
The utility model has the following beneficial effects:
This it is practical can be achieved under limited conditions, spiral shell can be effectively improved by not increasing under structure design difficulty and use cost
The reliability of line connection, increases self-locking anti-loosing ability, avoids a possibility that bringing security risk because of thread looseness.The letter of its structure
It is single, it is convenient for disassembly and assembly, implementation can be directly improved on plain nut, at low cost, maintainability is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the different angle bevel structure schematic diagram of the utility model；
The appended drawing reference table of comparisons:
1- nut, 2- gasket, the inclination angle 3- inclined-plane two, the inclination angle 31- inclined-plane one, 4- fulcrum, 5- bolt.
Specific embodiment
Further illustrate specific embodiment of the present utility model with reference to the accompanying drawing.Wherein identical components phase
Same appended drawing reference indicates.It should be noted that word "front", "rear" used in the following description, "left", "right", "upper" and
"lower" refers to that the direction in attached drawing, word "inner" and "outside" refer respectively to the side towards or away from geometric center of specific component
To.
In order to make the content of the utility model be easier to be clearly understood, below in conjunction in the utility model embodiment
Attached drawing, the technical scheme in the utility model embodiment is clearly and completely described.
As shown in Figure 1, 2, a kind of screw thread self-locking locking device based on inclination angle inclined-plane, comprising: inclined-plane 1 with angle
The gasket 2 of nut 1 and inclined-plane with angle 23, during tightening nut 1 and gasket 2, the inclination angle inclined-plane 1 and gasket
2 points first contacted or inclination angle inclined-plane 23 and the point that nut 1 first contacts are fulcrum 4, at the form of thread of the nut 1 and bolt 5
Generate moment of flexure, the form of thread generation flexible deformation of the nut 1 and bolt 5.
In the device use process, by the nut 1 on inclined-plane 1 with angle or increase the gasket 2 on inclined-plane 23 with angle,
During applying screw-down torque, the place first contacted using inclination angle inclined-plane and nut 1 makes nut 1, bolt 5 as fulcrum
Partial threads on generate certain moment of flexure, make its tooth form that flexible deformation occur, and then moment of friction be significantly greatly increased and plays screw thread
The purpose of self-locking anti-loosing.The design at its inclination angle and material, list processing, tooth form structure and the matched spiral shell of nut 1
5 material of bolt, specification are related.
Embodiment 1: the M10 nut with 8 ° of inclination angles inclined-plane is threadedly coupled with bolt, applies the screw-down torque of 45Nm,
Test is compared with the threaded connection of common M10 nut bolt under mutually same vibration environment, anti-loosing effect of the invention is
4 times of normal thread connection.
The foregoing is merely the preferred embodiment of the utility model patent, it is not intended to limit the utility model specially
Benefit, all made any modifications, equivalent replacements, and improvements etc. within the spirit and principle of the utility model patent should all include
Within the protection scope of the utility model patent.
