Description
Technical field
This utility model belongs to the technical field of locking nut, particularly relates to a kind of lock nut assembly.
Background technology
The connection that bolt and nut is usually used between each type component is fixed, or transmission linear motion, and general bolt and nut is as even
Connect securing member to get loose owing to other reasons such as vibration can be easily generated in use process, for preventing this phenomenon, had double
Part formula lock nut assembly.Existing two pieces type lock nut assembly is by the mother nut of a rotatable fastening and a self-locking nut
Composition.Mother nut one end arranges cone elastic thread pawl and configures external screw thread, self-locking nut and external screw thread phase configuration, and arranges taper hole
For tightening up cone elastic thread pawl, thus realize the locking of mother nut.
The locking torque of above-mentioned lock nut assembly is consistent owing to the conicity of conical surface taper hole first is difficult to processing, bores when second tightening up
The conicity in face can change again, and therefore, contact condition between the two is often linear contact lay, and not only coupling mechanism force is less, and makes
Still suffering from getting loose hidden danger due to other reasons such as vibrations by process, the ability of its anti-vibration is relatively low.Additionally, tightening locking nut
Time, tightening tool can be blocked owing to tightening locking nut bottom without lug, therefore, it is very easy to occur that tightening tool moves down into master
Nut is so that mother nut rotates together with locking nut, and occurs that locking nut does not tighten the risk of mother nut.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lock nut assembly, and it is not only simple in structure, and arranges conjunction
Reason, can be effectively improved coupling mechanism force.
This utility model solves its technical problem and be the technical scheme is that a kind of lock nut assembly, it is characterised in that bag
Including mother nut and self-locking nut, described mother nut top center is provided with flange, and described flange lower is cylindrical tube structure, flange
Top is the tube structure of Diameter Gradual Change, and flange lower is provided with external screw thread, and described external screw thread matches with the screw of described self-locking nut
Putting, flange inside center is provided with inner bolt hole, and self-locking nut top center has the groove of Diameter Gradual Change, described groove and flange phase
Configuration, the diameter of flange successively decreases from lower to upper, and the diameter on groove top is incremented by along self-locking nut top down.
By such scheme, the central axis of described flange top intersects or eccentric setting with the central axis of mother nut, described groove
The central axes of central axis and self-locking nut.
By such scheme, the central axis of described flange top and the central axes of mother nut, the central axis of described groove
Intersect or eccentric setting with the central axis of self-locking nut.
By such scheme, described self-locking nut bottom outer-edge is provided with the center of block, described block outermost end and described self-locking nut
The distance of axis is more than or equal to the radius of the minimum circumscribed circle of self-locking nut.
By such scheme, described block is the lug extended centrally out bottom described self-locking nut side or along self-locking nut
Bottom outer circumference stretch out formation block structure.
By such scheme, described block is provided with letter or number or word or breach or hole or line ball or impression identifies.
The beneficial effects of the utility model are: provide a kind of lock nut assembly, when tightening mother nut and self-locking nut, recessed
Groove is engaged mutually with flange top, flange lower and mother nut bolt, increases the coupling mechanism force of nut assembly, improves the energy of anti-vibration
Power, eliminates the hidden danger that gets loose.

Detailed description of the invention
For being more fully understood that this utility model, the utility model will be further described with embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of lock nut assembly, including mother nut 1 and self-locking nut 2, mother nut top center is provided with
Flange 4, flange lower is cylindrical tube structure, and top is the tube structure of Diameter Gradual Change, and flange lower is provided with external screw thread, outward
Screw thread and the screw phase configuration of described self-locking nut, flange inside center is provided with inner bolt hole, and self-locking nut top center has diameter
The groove 3 of gradual change, groove and flange phase configuration, the diameter of flange successively decreases from lower to upper, and the diameter on groove top is along self-locking nut
Top down is incremented by, and wherein, the central axis of flange top intersects or eccentric setting with the central axis of mother nut, in groove
Mandrel line and the central axes of self-locking nut；Or, the central axis of flange top and the central axes of mother nut,
The central axis of groove intersects or eccentric setting with the central axis of self-locking nut.
Self-locking nut bottom outer-edge is provided with block 5, and block outermost end and the distance of the central axis of self-locking nut are more than or equal to upper
The radius of the minimum circumscribed circle of nut, when using tightening tool to tighten self-locking nut, tightening tool will be resisted against on block, because of
This, tightening tool will not slide to mother nut and engage with mother nut, so will tighten self-locking nut easily, and tightening tool can
For impact wrench 7.
Block is the lug extended centrally out bottom self-locking nut side or stretches out shape along outer circumference bottom self-locking nut
The block structure become.Block is provided with letter or number or word or breach or hole or line ball or impression identifies, and is seen by naked eyes
Examine the anglec of rotation that can conveniently see self-locking nut, so, we can also fastening nut, while turning added by Jian Chaing
Square.
When using this anti-loosen screw nut component, first mother nut is tightened on bolt 6 with a predetermined torque, then, by self-locking spiral shell
Mother is tightened on bolt with another predetermined torque, and the torque of mother nut and self-locking nut can set according to practical situation.
When tightening self-locking nut, the block on self-locking nut will withstand impact wrench, such impact wrench when tightening self-locking nut just
Will not move down and be meshed with mother nut, thus tighten self-locking nut very easily.
When tightening self-locking nut, the angle that self-locking nut rotates can be judged, such that it is able to easily judge by observing block
Whether self-locking nut is tightened with predetermined torque.Operational circumstances in detail is as follows: when self-locking nut touches mother nut soon, I
Be rotating slowly impact wrench, when self-locking nut just touches mother nut, the flange of eccentric setting inserts in groove or convex
When edge inserts in the groove of eccentric setting, we can feel needs to increase an obvious torque (self-locking nut is not in contact with to leading
Torque the least is had only to before nut), at this moment, we have only to detect by an unaided eye and record the initial position of block, so
By impact wrench, self-locking nut is turned to the angle (torque corresponding to predetermined) of a fixed value afterwards, due to mother nut and self-locking
The tight occlusion of nut, is applied with axial force to bolt, increase nut assembly coupling mechanism force and with the frictional force of bolt, prevent
Nut gets loose.
