Description
Technical field
This utility model belongs to torsion spring technical field, is specifically related to a kind of torsion spring.
Background technology
The purposes of spring widely, the almost indispensable element of common mechanical, when it is by External Force Acting, i.e. produces elastic deformation, thus store strain energy and disengage at random.Torque spring at spring kind apoplexy due to endogenous wind is dependent on its torsional elasticity and produces frictional force with transmission power or the spring of motion, wherein there is a kind of torsion spring torsion spring, also known as twins torsion spring, as the term suggests being made up of two spring bodies, it is dependent on its torsional elasticity and produces frictional force with transmission power or the spring of motion, but existing torsion spring also exists: structural strength is low, torsion is little, poor stability, when stress is bigger or discontinuity equalization, the problems such as being easily deformed, during use, spring is easy to fall off, and service life is short.
Utility model content
The purpose of this utility model is to provide a kind of torsion spring, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of torsion spring, including arch connecting rod and spacing interior bar, described arch interlinking lever end is all fixedly installed spring body, described spring body outboard end is fixedly installed connecting rod, described connecting rod side is provided with spacing loop bar, described spacing loop bar inwall both sides are provided with chute, described spacing interior bar one end is provided with baffle plate, the described spacing interior bar other end is provided with slide block, described spacing interior bar is connected with slide in spacing loop bar inside by slide block, the end of described connecting rod is provided with installing hole.
Preferably, described arch connecting rod, spring body, connecting rod and installing hole is connected as a single entity structure and the rhabodoid made by a Steel material rolls and forms.
Preferably, described spring body overlaps with equal sized, the centrage of described spring body, and the number of turns of spring body is at least two circles.
Preferably, the internal diameter of described spacing loop bar is than big 0.2mm～0.5mm of diameter of spacing interior bar, and the diameter of baffle plate is all higher than the internal diameter 0.1-2mm of spacing loop bar.
nullTechnique effect of the present utility model and advantage: this torsion spring，Installing hole is arranged on fixing point by screw，Make torsion spring stability in use high，It is difficult to slip，After arch connecting rod is pulled certain angle，If needing arch connecting rod to keep this position can fix arch connecting rod by slide in the spacing loop bar baffle plate of the most spacing interior bar one end of spacing interior bar，The torsion increasing torsion spring can be played，Arch connecting rod、Spring body、Connecting rod and installing hole are connected as a single entity structure and the rhabodoid made by a Steel material rolls and forms，Thus the structural strength improving torsion spring is deformed with reducing torsion spring，Spring body is equal sized with spring body、Centrage overlaps，And the number of turns be at least two circles thus ensure uniform force and improve spring body torsion，Make torsion spring more stable，Improve its service life，This apparatus structure is simple，Easy to operate，Stability is strong，It is difficult to during use slip，Easy for installation，Two-man act body designs，High torsion，Deflecting force it is not likely to produce during use，It is unlikely to deform，Service life is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 arch connecting rod, 2 spring bodies, 3 connecting rods, 4 spacing loop bars, 5 chutes, 6 slide blocks, 7 spacing interior bars, 8 baffle plates, 9 installing holes.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
This utility model provides a kind of torsion spring as shown in Figure 1, including arch connecting rod 1 and spacing interior bar 7, described arch connecting rod 1 end is all fixedly installed spring body 2, described spring body 2 outboard end is fixedly installed connecting rod 3, described connecting rod 3 side is provided with spacing loop bar 4, described spacing loop bar 4 inwall both sides are provided with chute 5, described spacing interior bar 7 one end is provided with baffle plate 8, described spacing interior bar 7 other end is provided with slide block 6, described spacing interior bar 7 is slidably connected with chute 5 in spacing loop bar 4 inside by slide block 6, the end of described connecting rod 3 is provided with installing hole 9.
Further, described arch connecting rod 1, spring body 2, connecting rod 3 and installing hole 9 are connected as a single entity structure and the rhabodoid made by a Steel material rolls and forms.Thus the structural strength improving torsion spring is deformed with reducing torsion spring.
Further, described spring body 2 overlaps with equal sized, the centrage of described spring body 2, and the number of turns of spring body 2 is at least two circles.Ensure uniform force and improve the torsion of spring body 2, making torsion spring more stable, improve its service life.
Further, the internal diameter of described spacing loop bar 4 is than big 0.2mm～0.5mm of diameter of spacing interior bar 7, and the diameter of baffle plate 8 is all higher than the internal diameter 0.1-2mm of spacing loop bar 4.Guarantee that spacing interior bar 7 can be convenient when spacing loop bar 4 internal slide.
