I. the first embodiment
According to the locking screw fastening piece of first embodiment of the present invention structure, shown in Fig. 1-5, and be denoted as substantially 40.Although be shown fixing nut or locking nut in Fig. 1-5, those skilled in the art will recognize that, design of the present invention can be incorporated in multiple fastening piece.
Threaded fastener 40 comprises body 42 and locking element, spring or hoop 44.Body 42 comprises Hexagon outside 46, and it is configured to engage conventional driving tool (not shown) and is driven by conventional driving tool.Hexagonal part 46 comprises a plurality of bights 48 and a plurality of planes 50 of extending betwixt.Alternatively, 42 can be square, other polygonal, or any other shape.Body 42 also can be shaped to by any conventional driving tool at present known or exploitation later and engage.
Body 42 limits perforate 52, and it has screw thread at least in part along its length.As perhaps illustrated best in Fig. 3, perforate 52 comprises threaded first portion 54, and does not have threaded second portion, depression, recess or retaining piece wall 56.The diameter of unthreaded portion 56 is greater than the diameter of helical thread portion 54.Lower lips 60 is opened the first and second parts for 54,56 minutes.
Body 42 also limits first or the grappling recess 62 that are communicated with perforate 52 and second or discharge recess 64.Alternatively, one or both in recess 62,64 can be limited by retaining piece part 90.The first and second recesses 62,64 are limited in the inside of body 42, so that the environment isolation around of the first and second recesses 62,64 and fastening piece body 42.
Locking strap 44 comprises wire rod or continuous bend part 70, and it has the circular cross-section of extending between the first tang or end 72 and the second tang or end 74.Although illustrate with circular cross-section, can envision other sectional shape, comprise square, rectangle, ellipse, triangle and any other applicable shape.
In current embodiment, the first and second tang or end the 72, the 74th, straight, but also can envision other shape that comprises smoothed curve and angle.Perhaps as illustrated best in Fig. 4, two tang 72,74 tangentially stretch out from curved section 70.Also as shown in Figure 4, locking strap 44 can comprise single turn, and wherein the first tang 72 and the second tang 74 are overlapping.Locking strap 44 can alternatively comprise and is less than single turn, or two or more helical circle, so that adjacent circle roughly contacts with each other.If locking strap 44 comprises, be less than single turn, locking strap 44 can extend completely in the single plane perpendicular to perforate 52 ground orientations, or can spirally extend.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 is substantially corresponding to the pitch of externally threaded item 45, so that locking strap 44 is engaged in the screw thread of threaded part 45.In having the locking strap of noncircular cross section, the surperficial large I of engage threads parts 45 screw threads is less than, is equal to or greater than substantially the pitch of threaded part.
The tang 72 tangentially extending is taken in and is constrained in the first recess 62 in fastening piece body 42.As shown in Figure 3, the first recess 62 has sidewall 80, and it retrains the first tang 72 and moves with respect to the angle of body 42.For example, fastening piece body 42 along installation or clockwise direction and along remove or counterclockwise rotation during, the side surface of the first tang 72 can contact sidewall 80.The first recess 62 can comprise breach 66, to allow the side surface of the first tang 72 to coordinate with respect to sidewall 80 with flushing.Replace sidewall 80 or except sidewall 80, the first recess 62 can have end wall 82, sidewall 80 engages the end face of the first tang 72 during body 42 rotates.As shown in the figure, end wall 82 can be approximately perpendicular to sidewall 80, or can be angled with respect to sidewall 80.Alternatively, the first recess 62 can be configured to engage bight or any other applicable surface of the first tang 72 during 42 rotations of fastening piece body.As shown in Figure 2, the first recess sidewall 80 is oriented with perforate 52 tangent substantially, to take in tangential tang 72.Therefore, tang 72 is fixed along angle with respect to body 42.
The second tang 74 of locking strap 44 extends in the second recess 64.The second tang 74 generally freely rotates along angle in the second recess 64 with respect to body 42.Yet as mentioned below and as shown in Figure 2, the second tang 74 can contact the second recess wall 84 during the removing or be rotated counterclockwise of body 42, this has limited the second tang 74 and has moved with respect to the angle of body 42.
Although be shown two recesses 62,64, instead, body 42 can limit the combination on recess and/or surface to take in each in tang 72,74.
Threaded fastener 40 along first or substantially clockwise direction be installed in externally threaded item 45 and make locking strap 44 expansions so that locking strap 44 does not disturb or stop threaded fastener 40 to move in externally threaded item 45.Yet, threaded fastener 40 along remove or substantially anticlockwise rotary manipulation become to pull locking strap 44 securely against screw thread, effectively prevented thus unexpected, unexpected or unexpected unclamping that threaded fastener 40 for example causes due to vibration.
If enough moments of torsion are applied to body 42, the expectation of locking strap 44 permission threaded fasteners 40 unclamps.If body 42 under enough moments of torsion along second or counterclockwise rotation, by the first recess 62 angles the first flexibly deflection of tang 72 of retraining, this allow again body 42 with respect to locking strap 44 rotations by little angle.As shown in Figure 2, this rotation promotes the second tang 74, the second tang 74 tangentially extends from wire rod part 70, contacts with the second recess wall 84 in nut body 42.As shown in the figure, contact can be between the end face of the second tang 74 and the bight of the second recess 64, or can be between any two surfaces that constraint the second tang 74 is moved with respect to the angle of body 42.When applying when removing moment of torsion and making fastening piece 40 rotation leave externally threaded item 45, this contact reduces or may eliminate any further increase of the stress aspect on locking element 44.Therefore, outside thread or locking element 44 are existed less or do not have destruction.The second recess 64 can be designed to by allowing the predetermined mobile degree of the second tang 74 to be controlled to predetermined or preselected level by removing moment of torsion.
When applying, remove moment of torsion and hoop 44 flexibly during deflection, the first tang 72 marginally slides along the first recess sidewall 80.This tangentially mobile degrees of freedom reduces or may eliminate the stretching in hoop 44, and level and smooth without wearing and tearing operation after having guaranteed repeatedly to re-use.When fastening piece 40 and outside thread, remove completely while engaging, hoop 44 is flexibly got back to its home position.
The diameter of locking strap 44 may be selected to so that single locking strap 44 can be used with together with all outside thread classifications in specific thread size.Locking strap 44 has been found that single locking strap 44 can " adjustment automatically " adapt to various screw thread classifications at least in part, because can slide along the first recess sidewall 80.Alternatively, can design different locking strap 44 uses together with the different outside thread classifications in the thread size from different or specific thread size.In addition, the sectional shape of locking strap 44, the strength of materials and elasticity can be selected in the application based on expectation.
Body 42 and locking strap 44 can be manufactured by any applicable material, comprise metal and composite material.In addition,, due to the stress reducing in locking strap 44 between 40 spreadable lifes at threaded fastener, locking strap 44 can be made by the material (such as Round Steel Wire) of relatively low cost.
