Abstract
The utility model relates to a terminal surface hinders favourable turn tool locking device for threaded connection, including the screw bolt and nut, characteristics lie in all open threaded hole on the screw bolt and nut, simultaneously corresponding to this screw hole by bolted connection's last connector with bore the shallow bore hole on the connector down, the tip inserts the shallow bore hole behind the above -mentioned screw hole of the wrong income of cylindrical end holding screw. The utility model discloses mainly the method through machinery prevents that the fastener from rotating to reach the mesh that prevents the vice pine of screw thread and take off.
Description
Technical field
This utility model relates to a kind of threaded mechanical locking device, particularly relates to a kind of for threaded end face resistance favourable turn tool locking device, is mainly used in threaded locking of all kinds of plant equipment.
Background technology
Threaded is a kind of dismountable fixing connection, has the advantages such as simple in construction, connection is reliable, be convenient to mount and dismount, is widely used in mechanical engineering, structure connection area.Threaded typically have self-locking performance, and the frictional force on the supporting surface of nut and bolt head also has locking effect in addition, therefore typically will not get loose after tightening.But under shock and vibration or varying load effect, and when high temperature or variations in temperature are bigger, the frictional force between screw thread can reduce or disappear moment, couples it is possible to loosen.Though traditional machinery is locking certain effect, but its reliability is relatively low, is not suitable for the occasion that requirement is higher.
Summary of the invention
The purpose of this utility model is to overcome the defect of above-mentioned prior art, it is provided that one effectively prevents screw thread pair from getting loose, and that improves threaded reliability hinders favourable turn tool locking device for threaded end face.
The technical scheme taked for achieving the above object is:
A kind of for threaded end face resistance favourable turn tool locking device, including screw bolt and nut, it is characterized in that: on described screw bolt and nut, all have screwed hole, simultaneously corresponding to boring shallow bore hole on the upper connector being bolted connection of this screwed hole and lower connector, cylinder end clamping fixed screw is screwed into above-mentioned screwed hole rearward end and inserts shallow bore hole.
The cylindrical end of described cylinder end clamping fixed screw inserts shallow bore hole.
This utility model mainly prevents fastener rotation by the method for machinery, thus reaches the purpose preventing screw thread pair from getting loose.
Accompanying drawing explanation
Fig. 1 is this utility model for threaded end face resistance turns the structural representation sketch of locking device, in figure, and 1, nut；2, bolt；3, screwed hole；4, cylinder end clamping fixed screw；5, upper connector；6, lower connector；7, shallow bore hole.
Detailed description of the invention
As shown in Figure 1, this utility model turns locking device for threaded end face resistance, after upper connector 5 and lower connector 6 are connected by nut 1 and bolt 2 with the form of screw thread pair and apply pretightning force, nut 1 and bolt 2 just have the trend reversely return along pre-fastening moment applying direction, nut 1 and bolt 2 once occur reversely to return screw thread pair will loosen inefficacy, as long as therefore stoping nut 1 and bolt 2 to rotate, it is possible to effectively to prevent screw thread pair from loosening and lost efficacy.
To this end, the locking device that this utility model relates to is to open screwed hole 3 on existing bolt 2 and nut 1.Form after screw thread pair completes pretension at nut 1 and bolt 2, by the screwed hole 3 of nut 1 and bolt 2 upper connector 5 and nut 1 coordinate face and lower connector 6 and bolt 2 coordinate preboring shallow bore hole 7 on face, subsequently cylinder end clamping fixed screw 4 is threaded into hole 3, and make the cylindrical end of cylinder end clamping fixed screw 4 insert the shallow bore hole 7 of preboring, play machinery anti-rotation and then locking effect.
Owing to expendable plastic deformation can be produced between the screw thread pair of long-time engagement, therefore this locking device carries out the phenomenon that there will be the screwed hole 3 that there is matching relationship before this during secondary installing with shallow bore hole 7 generation dislocation after removal, for this phenomenon, can preboring shallow bore hole 7 again, and use remaining screwed hole to carry out resistance turn, the relative position of screwed hole 3 and shallow bore hole 7 can also be adjusted at nut 1 suitable thin pad added below, after making it re-establish corresponding relation, then it is locking to carry out resistance turn with cylinder end clamping fixed screw 4.
Claims (2)
1. one kind is hindered favourable turn tool locking device for threaded end face, including bolt (2) and nut (1), it is characterized in that: on described bolt (2) and nut (1), all have screwed hole (3), simultaneously boring shallow bore hole (7) on the upper connector (5) connected corresponding to being bolted of this screwed hole (3) (2) and lower connector (6), cylinder end clamping fixed screw (4) is screwed into above-mentioned screwed hole (3) rearward end insertion shallow bore hole (7).
2. according to described in claim 1 for threaded end face resistance favourable turn tool locking device, it is characterised in that the cylindrical end of described cylinder end clamping fixed screw (4) inserts shallow bore hole (7).
