Abstract
The utility model discloses a kind of springs, include left-handed torsional spring body and dextrorotation torsional spring body, the linking arm of both connections are provided between the left-handed torsional spring body and dextrorotation torsional spring body, the left-handed torsional spring body and the respective one end of dextrorotation torsional spring body are respectively provided with spring arm；The left-handed torsional spring body and dextrorotation torsional spring body are formed by the rotation coiling of at least one spring coil, have gap between the spring coil, to form whole axial elastic force.Torsional moment can not only be transmitted, additionally it is possible to provide axial elastic force, and there are two torsional spring bodies for tool, torsion is bigger and more stable, can be suitable for the occasion for not only needing torsion but also needing axial elastic force, and applicability is stronger.
Description
Technical field
The utility model relates to elastic component field, specifically a kind of spring.
Background technique
In the prior art, the form of spring is varied, according to stress property, can be divided into extension spring, compressed spring, torsion
Turn spring etc..The torsionspring more generally used is applicable in load caused by torsional moment, and the direction of the torsional moment is general
With axle of spring at right angle, two spring arms of torsionspring are located at the both ends of torsional spring ontology, to form torsional moment.So
And can not be applicable under certain scenes, only transmitting torsional moment, use scope is more limited to.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of scope of application
Wider array of spring.
The technical solution of the utility model includes: include left-handed torsional spring body and dextrorotation torsional spring body, the left-handed torsional spring body and the right side
The linking arm of both connections is provided between turn-knob spring body, the left-handed torsional spring body and the respective one end of dextrorotation torsional spring body have respectively
There is spring arm；The left-handed torsional spring body and dextrorotation torsional spring body are formed by the rotation coiling of at least one spring coil, are had between the spring coil
Gap, to form whole axial elastic force.
Preferably, linking arm includes to be located in the middle interconnecting piece, prolong portion on two and positioned at the two of interconnecting piece two sides
A bending part, the interconnecting piece in axial direction be arranged, it is described two on prolong portion respectively with left-handed torsional spring body, dextrorotation torsional spring body connect
Connect and be separately connected corresponding bending part, the bending part and above prolong portion's shape in the plane perpendicular to axis it is in 90 ° ~ 120 °
Angle.
Preferably, angle is set as 106 °.
Preferably, left-handed torsional spring body, dextrorotation torsional spring body, linking arm and the setting of spring arm are structure as a whole, and described left-handed
Torsional spring body and the symmetrical mode of dextrorotation torsional spring body are arranged.
Preferably, above prolong the angle in 132 ° ± 3 ° of portion and spring arm formation.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model can not only transmit torsional moment, additionally it is possible to provide axial elastic force, and there are two turn round for tool
Spring body, torsion is bigger and more stable, can be suitable for the occasion for not only needing torsion but also needing axial elastic force, and applicability is stronger.
2, it can be used for accommodating external device between two bending parts of linking arm, be against interconnecting piece on device, from
And transmit reliable torsional moment.
Detailed description of the invention
Fig. 1 is the main view of the utility model specific embodiment；

Spring body 1 and the symmetrical mode of dextrorotation torsional spring body 2 are arranged, and facilitate the processing and manufacturing of device.Left-handed torsional spring body 1 and dextrorotation torsional spring body
2, which rotate coiling by the spring coil 11 of two circles, forms, and has gap 12 between spring coil 11, makes the section with 0.1mm or more between spring coil 11
Away to form the elastic force of whole axial direction.Left-handed torsional spring body 1 or 2 drift of dextrorotation torsional spring body are 5.2mm, and line footpath is
0.9mm encloses several two circles, then pitch is about 2.15mm, and length is about 2.5mm after compression.
Linking arm 3 includes to be located in the middle on interconnecting piece 31, two to prolong portion 32 and positioned at the two of 31 two sides of interconnecting piece
A bending part 33, interconnecting piece 31 are arranged in axial direction, prolong portion 32 on two and connect respectively with left-handed torsional spring body 1, dextrorotation torsional spring body 2
Corresponding bending part 33 is connect and be separately connected, above prolongs portion 32 and is extended by the tangential direction of left-handed torsional spring body 1, dextrorotation torsional spring body 1
Out；Bending part 33 with above prolong the shape in the plane perpendicular to axis of portion 32 it is in 90 ° ~ 120 ° of angle, angle is preferably 106 °,
On prolong the angle that portion 32 and spring arm 4 form 132 ° ± 3 °.
