The multiple planes 50 betwixt extending.Alternatively, 42 can be square, other polygons, or any other shape.Body 42
Also can shape is to be engaged by any routine driving instrument of exploitation that be currently known or later.
Body 42 limits perforate 52, and it has screw thread along its length at least in part.Perhaps it is best shown at as in Fig. 3,
Perforate 52 includes threaded Part I 54, and does not have threaded Part II, depression, recess or retaining piece wall 56.No spiral shell
The diameter with diameter greater than threaded portion 54 of stricture of vagina part 56.First and second parts is opened for 54,56 points by lower lips 60.
Body 42 is further defined by first connecting with perforate 52 or grappling recess 62 and second or release recess 64.Alternatively,
One of recess 62,64 or the two can be limited by retaining piece part 90.First and second recesses 62,64 are limited to body 42
In inside, so that being environmentally isolated around the first and second recesses 62,64 and fastener body 42.
Locking strap 44 includes wire rod or continuous bend part 70, its have in the first tang or end 72 and the second tang or
The circular cross-section extending between end 74.Although illustrating with circular cross-section, other cross sectional shapes can be devised, including square
Shape, rectangle, ellipse, triangle and any other suitable shape.
In the present example, the first and second tang or end 72,74 are straight, but it is also contemplated that go out including smooth song
Line and the other shapes of angle.Perhaps be best shown at as in Fig. 4, two tang 72,74 from sweep 70 tangentially to
Outer extension.Also as shown in Figure 4, locking strap 44 may include single turn, and the wherein first tang 72 is overlapping with the second tang 74.Locking strap
44 can alternatively include less than single turn, or two or more helical circle, so that adjacent circle substantially contacts with each other.If locking strap
44 include less than single turn, then locking strap 44 can be fully extended in the single plane that perforate 52 ground orients, or can spiral
Shape ground extends.As shown in figure 4, locking strap 44 can be symmetrical, to simplify manufacture.
The diameter of the circular cross-section of locking strap 44 substantially corresponds to the pitch of externally threaded item 45, so that locking strap 44 is joined
It is combined in the screw thread of screwed part 45.In the locking strap with noncircular cross section, engage the surface of screwed part 45 screw thread
Size is smaller than, is substantially equal to or greater than the pitch of screwed part.
In the first recess 62 that tangentially extending tang 72 is received and constrained in fastener body 42.As shown in figure 3,
First recess 62 has side wall 80, and its constraint first tang 72 is with respect to the angular movement of body 42.For example, in fastener body
42 along install or clockwise and along remove or counterclockwise rotates during, the side surface of the first tang 72 can contact side wall
80.First recess 62 may include breach 66, is coordinated with flushing with respect to side wall 80 with the side surface allowing the first tang 72.Replace
Side wall 80 or in addition to side wall 80, the first recess 62 can have end wall 82, and side wall 80 engages the first handle during body 42 rotation

Threaded fastener 40 is mounted to substantially externally threaded item 45 in make locking strap 44 to expand along first or clockwise
, so that locking strap 44 does not disturb or stops threaded fastener 40 from moving in externally threaded item 45.However, threaded fastener 40
Edge removes or generally anticlockwise rotation process becomes to pull locking strap 44 securely against screw thread, is thus effectively prevented
What threaded fastener 40 was for example caused due to vibration unexpected, unexpected or unexpected unclamps.
If enough moments of torsion are applied to body 42, locking strap 44 allows the desired of threaded fastener 40 to unclamp.As
Fruit body 42 is in enough moment of torsion lower edges second or counterclockwise rotates, then the first handle angularly being constrained by the first recess 62
Foot 72 can flexibly deflect, and this allows body 42 to be rotated through little angle with respect to locking strap 44 again.As shown in Fig. 2 this rotation
Turn and promote the second tang 74, the second tang 74 is tangentially extending from wire rod part 70, with the second recess wall in nut body 42
84 contacts.As illustrated, contact between the corner of the end face of the second tang 74 and the second recess 64, or can will constrain the
Between any two surface with respect to the angular movement of body 42 for two tang 74.When applying removes moment of torsion to make securing member 40 revolve
Over leaving during screwed part 45, this contact reduces or may eliminate any further of the stress aspect on locking element 44
Increase.Therefore, external screw thread or locking element 44 are existed less or there is not destruction.Second recess 64 may be designed to by allowing
The predetermined mobile degree of the second tang 74 becomes predetermined or preselected level by removing moment of torsion control.
When applying to remove moment of torsion and bind round 44 flexibly deflection, the first tang 72 is marginally slided along the first recess sidewall 80
Dynamic.This degree of freedom tangentially moving reduces or may eliminate the stretching in hoop 44, and ensure that flat after repeatedly reusing
Sliding no abrasion operation.When securing member 40 and the complete debonding of external screw thread, hoop 44 flexibly returns to its home position.
The diameter of locking strap 44 may be selected to single locking strap 44 can with specific thread size in all external screw threads
Classification is used together.It has been found that single locking strap 44 " adjust automatically " can adapt to various screw thread classifications at least in part, because

98 protections being made to the sufficiently high aspiration level with offer to locking strap 44, then can eliminate retaining piece lid 96.
Retaining piece lid 96 can be any kind of suitable shape, including cylindrical pad flake shape as depicted.Retaining piece
Lid 96 can suitably determine size for application.For example, the internal diameter of retaining piece lid 96 can be set to be slightly larger than in terms of size
Screwed part 45, to allow screwed part 45 to pass through the complete gap of retaining piece lid 96.Alternatively, the internal diameter of retaining piece lid 96 can
It is set to closely interact with the screw thread of screwed part 45 in terms of size.And alternatively, the internal diameter of retaining piece lid 96
Screwed part 45 can be set smaller than in terms of size.Retaining piece lid 96 can be made up of any suitable material, including metal, again
Condensation material and flexible material.If the internal diameter of especially retaining piece lid 96 is set smaller than screwed part 45 in terms of size,
Retaining piece lid 96 can be made up of flexible material (such as elastomer), to provide the sealing with respect to screwed part 45, to prevent dirt
Dirt and chip enter retaining piece part 90.
The installation of locking strap 44 can be realized in many ways.In the present example, hoop 44 passes through fully to make it press
Contracting come to make it block in hlding part 90 to take in place installing.Hoop 44 in place after, retaining piece lid 96 can with card collocation conjunction,
Frictional fit, binding agent or any other suitable connected mechanism are installing.Alternatively, retaining piece lid 96 may be formed at retaining piece
On flange 98.And alternatively, locking strap 44 can wind in place.
Locking torque can be the function of the variable of some, including the material of the initial diameter of locking strap, locking strap
Matter, the coefficient of friction of locking strap, the number of turn of locking strap, and the shape and size of the first and second recesses 62,64.Additionally, parameter
Tolerance will affect the scope of the locking torque of particular configuration.Therefore, the parameter of locking strap 44 can be for each thread size and public affairs
Difference scope is chosen to provide the Slip torque of the ultimate strength less than locking strap 44, still provides acceptable locking torque model simultaneously
