Specific embodiment
The utility model is described in detail below in conjunction with attached drawing：Fig. 1,2 show one kind can any position locking
Linear motion device an original state, locking device 20 prevents it from passing through by internal self-locking spring latching bar axis 10
Housing component 20 is worn to move axially.Plectrum card slot 31 is placed in by rotating counterclockwise release plectrum 21 as indicated by the arrows of fig. 2
Interior, spring unlock, bar axis 10 and locking device 20 and the generation relative motion of housing component 30, then loose clockwise under external force
Acquittal puts plectrum 21, and spring locks bar axis 10, and the straight-line motion mechanism in this way is locked in new position.
To understand the embodiment of the utility model in more detail, Fig. 3 and Fig. 4 is please referred to；10 one end of bar axis is equipped with jointing
12 connect with motion, and 10 other end of bar axis limits the maximum displacement of bar axis 10 equipped with stopper ring 13, to prevent bar axis 10
Deviate from housing component 30 when mobile.
Around cylindrical bar 11 in 23 axial direction of self-locking spring 22 and self-locking spring, it is wound in reciprocal winding direction
Thereon, and they have there are one the normal direction internal diameter for being slightly less than bar diameter, to make two springs that can tightly clamp cylindrical bar 11.
The outer end of self-locking spring 22 and self-locking spring 23 folding hooks the fluting terminated in respectively on end bushings 34 and end tooth bushing 35.Self-locking
The inner end of spring 22 and self-locking spring 23 is engaged respectively on the notch of release plectrum 21, is coaxial with cylindrical bar 11, and
And it can be rotated by means of discharging plectrum 21 around cylindrical bar 11.Release plectrum 21 passes through inner housing 24 and outer housing 32 to stretch, and
And keep it in original locked position due to acting on spring tension on it.Release plectrum 21 rotates self-locking spring simultaneously
22nd, the inner end of self-locking spring 23, rotation direction are the windings of trip spring spring coil, amplify its internal diameter.It is in outer housing 32
The internal diameter of inner housing 24 between inner surface and self-locking spring 22, self-locking spring 23 is only slightly larger than self-locking spring 22, self-locking spring
23 normal direction outer diameters, thus inner housing 24 is made tightly to surround fastening spring.
When release plectrum 21 starts rotation, the interior inactive coil of self-locking spring unclamps winding, and its outer diameter is only slightly larger than
Its outer diameter before expanding, this is because its expansion is limited by its inner surface with inner housing 24；The release plectrum 21
Continuous moving is sequentially transmitted from the adjacent spring coil of outer spring end to its interior inactive coil, the expansion of the spring coil each to continue at this time by
The limitation of the inner surface close together to inner housing 24 finally results in the expansion of two all spring coils of spring, so as to discharge plectrum
21 can be such that bar axis 10 is moved axially by housing component 30.Release plectrum 21 is either rotated clockwise or is rotated counterclockwise,
Inner housing 24 is therewith moved to the same direction.
Housing component 30 described in the utility model is by plectrum card slot 31, outer housing 32, support base 33, end bushings 34 and end
Portion's tooth bushing 35 forms, and support base 33 is the connector with fixed mechanism opposite with jointing 12, and end bushings 34 are not
Direct stand under load, and the fixation of 22 end feet of self-locking spring is only prevented into its rotation, and support base 33 is one and carries support element, the branch
Support member bears most of or most service load, and the other parts of housing component 30 then have relatively small load, outside
End of 32 both ends of housing respectively with support base 33 and end bushings 34 crimps, therefore entire housing component is fixed.From
Spring 22 and self-locking spring 23 are locked in an axial direction between two opposed end bushings 34, end tooth bushings 35, support base 33
Coordinated with end tooth bushing 35 by teeth, pivoting end tooth bushing 35 changes the spring tension of self-locking spring 23 to eliminate spring
Along the clearance on bar axis 10 so as to be adjacent to spring.Plectrum card slot 31 is fixed on outer housing 32, when rotation release plectrum 21 arrives
Release plectrum 21 can be blocked during maximum position in the axial direction.
Embodiment：The utility model sets two self-locking springs, to bear bidirectional load, i.e., release plectrum is shared at one
Every side be provided with a self-locking spring, self-locking spring is installed in an axial direction between the bushing of housing component both ends, on each bushing
One respective springs of slotted engagement folding hook, prevent the rotation of around rod axis to fix the end feet of the spring and spring coil.The bullet
The other end of spring is connected on a release plectrum, which can manipulate two springs simultaneously makes it unclamp winding, to unclamp bar
Axis extends through shell and moves axially.The inner housing of an activity is cased in the outer ring of release plectrum and self-locking spring, for protecting
Shield spring simultaneously keeps the end feet of spring and release plectrum to be engaged.
It is only provided at one and connects between housing component and mechanism, i.e., with the support base axially supported.The other end is not straight
Receive load, and spring leg fixation is only prevented into its rotation.Therefore support base is a carrying supporting member, which bears
Most of or most service load, and the other parts of housing component then have relatively small load.
Spring-loaded be set as it is adjustable, for reducing spring along the clearance on bar.Adjustable axial bearing can be one
The toothed bushing in end face, tooth bushing coordinates with support base, and the fluting on the tooth bushing is engaged in an outer end end feet of spring,
By turning gear bushing so that spring is adjacent to, so as to eliminate the clearance along spring.
Tool is there are one the fixing piece being made of one with outer housing on housing component, for blocking release plectrum, when operation one
Handle or a locking wire, make release plectrum turn in the fixing piece card slot.
