Abstract
A kind of torque spring.It is related to a kind of machine components more particularly to a kind of torque spring.Provide a kind of torque spring that can effectively prevent deforming, being broken.Including spring body, the spring body includes intermediate bending section and the straightway at both ends, and the bending section, through there is through-hole, limit rope is equipped in the through-hole along draw direction, the limit rope passes through entire bending section, and to bending section both ends, the limit rope both ends are equipped with gag lever post；Fixing sleeve is equipped with compressed spring on straightway described in both ends.The present invention can effectively prevent the situation of torque spring deformation, fracture, and the setting of compressed spring can make torque spring work under crack conditions, until replacing.
Description
Technical field
The present invention relates to a kind of machine components more particularly to a kind of torque springs.
Background technology
Torque spring is that a kind of machinery stores power structure, and one end is fixed, and the other end is turned accumulation of energy, existing production and living
In, torque spring will appear deformation, phenomenon of rupture after turning repeatedly, seriously affect the production and living of people, producing can
The torque spring for alleviate deformation, being broken is extremely urgent.
Invention content
The present invention is in view of the above problems, provide a kind of torque spring that can effectively prevent deforming, being broken.
The technical scheme is that：A kind of torque spring, including spring body, the spring body includes the curved of centre
Tune and the straightway at both ends, the bending section, through there is through-hole, is equipped with limit rope along draw direction in the through-hole, described
Limit rope passes through entire bending section, and to bending section both ends, the limit rope both ends are equipped with gag lever post；
Fixing sleeve is equipped with compressed spring on straightway described in both ends.
The length of the limit rope is less than or equal to bending section largest deformation length.
The bending section is through there are two through-holes.
The spring body surface is zinc-plated.
Bending section draw direction is equipped with the through-hole through entire bending section in the present invention, and limiting is equipped in through-hole
Rope, can prevent bending section at work excessive tensile and cause deformation even fracture.The gag lever post at limit rope both ends is set on bending
Section both ends, the length of gag lever post is more than the width of through-hole, for fixing limit rope.
The torque spring situation that straightway is broken in use is most common, and at both ends, straightway fixation is arranged pressure
Even if after contracting spring straightway fracture after, compressed spring effect under, torque spring will continue to work, until to torque spring into
Row is replaced.
Description of the drawings
Fig. 1 is schematic structural view of the invention,
Fig. 2 is bending section sectional view；
1 is spring body in figure, and 2 be straightway, and 3 be bending section, and 4 be compressed spring, and 5 be gag lever post, and 6 be through-hole, and 7 be limiting
Rope.
Specific embodiment
As shown in Figs. 1-2, a kind of torque spring, including spring body 1, the spring body 1 includes intermediate the present invention
Bending section 3 and the straightway at both ends 2, the bending section 3, through there is through-hole 6, limiting are equipped in the through-hole 6 along draw direction
Rope 7, the limit rope 7 passes through entire bending section 3, and to 3 both ends of bending section, 7 both ends of limit rope are equipped with gag lever post 5；Spring sheet
Body is that the straightway at bending section and both ends is integrally formed, and in Fig. 2, laterally (draw direction) is equipped with through entire bending bending section
Section through-hole, and in through-hole be equipped with limit rope, can prevent bending section at work excessive tensile and cause deformation even fracture.
The gag lever post at limit rope both ends is set on bending section both ends, and the length a of gag lever post is more than the width of through-hole, for fixing limit rope.
Fixing sleeve is equipped with compressed spring 4 on straightway 2 described in both ends.Torque spring in use can be regular go out
The situation of existing both ends straightway fracture, at both ends, straightway fixation is arranged compressed spring, after straightway fracture, in compressed spring
Under effect, torque spring will continue to work, be replaced until to torque spring.
The length of the limit rope 7 is less than or equal to 3 largest deformation length of bending section.In this way, bending section is because by limit rope
Limitation, will not deformation it is excessive and be broken.
The bending section 3 is through there are two through-holes 6.Such as Fig. 2, two through-holes are respectively arranged on the top and bottom of bending section,
Limit rope is respectively equipped in two through-holes, can preferably prevent the deformation of spring body bending section in this way and is fractureed.
1 surface of spring body is zinc-plated.Spring surface is zinc-plated can to play the role of that torque spring is prevented to be broken.
