Abstract
The utility model belongs to the technical field of springs, and particularly relates to a spiral spring. The spiral spring solves the problem that an existing spiral spring is small in torque and easy to deform. The spiral spring comprises a spiral spring body. The spiral spring is characterized in that a first lug hook portion is arranged at the inner end of the spiral spring body, a connecting portion is arranged at the outer end of the spiral spring body in the tangential direction, the connecting portion is connected with a second lug hook portion, and the opening direction of the first lug hook portion and the opening direction of the second lug hook portion are arranged corresponding to each other. Compared with the prior art, the spiral spring has the advantages of being simple and reasonable in structure, high in strength, capable of avoiding the unhooking phenomenon caused by reactive force of the spiral spring, and high in torsion, resisting fatigue, and being 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 plane scroll 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.At spring kind midplane spiral spring, have another name called clockwork spring, be about to material and turn to planar spiral, the one end is fixed and the other end effect has moment of torsion; , in the distortion of torsional interaction lower spring material production bending elasticity, make spring planar produce torsion, thereby spring is in self plane generation torsion.The problems such as but existing plane scroll spring exists: structural strength is low, and torsion is little, and fatiguability is stressed when larger, easily produces distortion, breaks off relations because spring reaction power easily causes spring during use, 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 hand-pulling recoil starter scroll spring [application number: 02237626.7], comprises boot disk hook, spiral spring and boot disk post, the two ends bending of spiral spring, and the boot disk hook is connected with the inner of spiral spring; The length of part that described spiral spring is contacted with the boot disk hook is suitably extended, the length that makes described spiral spring and boot disk link up with the part that contacts is between the 1/4-1/2 girth of boot disk post, and it is bent into half crescent shape that is complementary with described boot disk post shapes.
The problem that has easily caused spring to break off relations due to spring reaction power when such scheme has solved existing plane scroll spring use to a certain extent, but this scheme still exists: and structural strength is low, and torsion is little, fatiguability, stressed when larger, easily produce 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 high torsion is difficult for the plane scroll spring that breaks off relations.
For achieving the above object, the utility model has adopted following technical proposal: this plane scroll spring, comprise spiral spring body, it is characterized in that, the inner of described spring body is provided with the first tack section, described spring body outer end tangentially is provided with joint, and described joint is connected with the second tack section, the opening direction of described the first tack section and the mutual corresponding setting of the opening direction of the second tack section.Improve the torsion of spring body, opening is oppositely arranged can avoid the spring body to break away from use.
In above-mentioned plane scroll spring, described spring body, the first tack section, joint and the second tack section are connected as a single entity structure.Improved structural strength.
In above-mentioned plane scroll spring, described spring body, the first tack section, joint and the second tack section are rolled and are formed by a section bar that is flat-shaped.Be convenient to processing.
In above-mentioned plane scroll spring, described section bar is made by Steel material.
In above-mentioned plane scroll spring, described spring body, the first tack section, joint and the second tack section are in the same plane.
Compared with prior art, the advantage of this plane scroll spring is: simple and reasonable, intensity is high, can avoid the unhook phenomenon that causes due to spring reaction power, high torsion, and antifatigue, not yielding, long service life.
Description of drawings
The structural representation that Fig. 1 provides for the utility model.
In figure, spring body 1, the first tack section 2, joint 3, the second tack section 4.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, this plane scroll spring, comprise spiral spring body 1, the inner of spring body 1 is provided with the first tack section 2, spring body 1 outer end tangentially is provided with joint 3, and joint 3 is connected with the opening direction of the second 4, the first tack sections 2 of tack section and the opening direction corresponding setting mutually of the second tack section 4, improve the torsion of spring body 1, opening is oppositely arranged can avoid spring body 1 to break away from use.
As a kind of technological scheme of comparatively optimizing, in the present embodiment, in order to improve structural strength, spring body 1, the first tack section 2, joint 3 and the second tack section 4 are connected as a single entity structure.Spring body 1, the first tack section 2, joint 3 and the second tack section 4 are rolled and are formed by a section bar that is flat-shaped, are convenient to processing.Section bar is made by Steel material.Spring body 1, the first tack section 2, joint 3 and the second tack section 4 are in the same plane.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
, although this paper has more used the terms such as spring body 1, the first tack section 2, joint 3, the second tack section 4, do not get rid of the possibility of using other term.Using these terms is only in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
