Abstract
The utility model belongs to the technical field of springs, and particularly relates to novel double torsional springs. The novel double torsional springs solve the problems that existing double torsional springs easily fall off in use, are poor in stability and the like, and comprise a first spring body and a second spring body which are oppositely arranged. The novel double torsional springs are characterized in that the central line of the first spring body and the central line of the second spring body coincide, one end, close to the second spring body, of the first spring body is connected with one end, close to the first spring body, of the second spring body through an arc-shaped connection rod, the other end of the first spring body is connected with a first installation rod, the other end of the second spring body is connected with a second installation rod, the first installation rod and the second installation rod are arranged in parallel, a first limiting structure is arranged on the first installation rod, and a second limiting structure is arranged on the second installation rod. The novel double torsional springs have the advantages of being simple and reasonable in structure, high in strength, capable of preventing the spring falling phenomenon from happening in use, high in torque, strong in stability, not prone to deformation and long in service life.
Description
Technical field
The utility model belongs to the spring technical field, especially relates to a kind of novel torsion spring.
Background technique
The purposes of spring is very extensive, is almost the indispensable element of common mechanical, when it is subjected to External Force Acting, namely produces resiliently deformable, thereby has stored strain energy and disengaged at random.Torsion spring in the spring kind, claim again twins' torsion spring,, as the term suggests two spring bodies, consist of, is to rely on its torsional elasticity to produce the spring of frictional force with transferring power or motion.The problems such as but existing torsion spring exists: structural strength is low, and torsion is little, and poor stability is stressed when larger or discontinuity equalization, easily produces distortion, and during use, spring easily comes off, and working life is short.
The problem that exists in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of torsion spring [application number: 201220493756.0] that is placed on Electropolating hangers, comprise two annular circles, an end of two described annular circles connects by arcuate head, and the other end of described annular circle connects the afterbody that is two-fold pin type.The radius of described annular circle is 6mm, and the angle between described arcuate head and horizontal plane is 75 °, and the distance between described afterbody is 12mm.
Caducous problem while using that such scheme has solved existing torsion spring to a certain extent, but this scheme still exists: and structural strength is low, and torsion is little, and poor stability is stressed when larger, easily produces distortion, the problem that working life is short.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, and stability is high, the novel torsion spring of difficult drop-off during use.
for achieving the above object, the utility model has adopted following technical proposal: this novel torsion spring, comprise the first spring body and the second spring body that are oppositely arranged, it is characterized in that, the center line of described the first spring body overlaps with the center line of the second spring body, described the first spring body is connected with the end of described the second spring body near the first spring body by the arch connecting rod near an end of the second spring body, the described first spring body the other end is connected with the first mounting rod, the described second spring body the other end is connected with the second mounting rod, and described the first mounting rod and the second mounting rod are arranged in parallel, be provided with the first limit structure on the first mounting rod, be provided with the second limit structure on the second mounting rod.
In above-mentioned novel torsion spring, described the first spring body and the second spring body measure-alike, and the number of turns of described the first spring body and the second spring body is at least a circle.
In above-mentioned novel torsion spring, described the first spring body, the second spring body, arch connecting rod, the first mounting rod and the second mounting rod all is connected as a single entity structure and by a rhabodoid, roll and form.
In above-mentioned novel torsion spring, described rhabodoid is made by Steel material.
In above-mentioned novel torsion spring, the first protuberance that radially protrudes that the end that described the first limit structure is the first mounting rod forms through extruding.
In above-mentioned novel torsion spring, the second protuberance that radially protrudes that the end that described the second limit structure is the second mounting rod forms through extruding.
Compared with prior art, the advantage of this novel torsion spring is: simple and reasonable, intensity is high, occurs the spring obscission in the time of avoiding using, high torsion, and stability is strong, and is not yielding, long service life.
