The orbital determined rods comprise the first orbital determined rod, the second orbital determined rod, the third orbital determined rod and the fourth orbital determined rod; the first orbital determined rod and the third orbital determined rod are located on the same central line; the second orbital determined rod and the fourth orbital determined rod are located on the same central line; the first orbital determined rod, the second orbital determined rod, the third orbital determined rod and the fourth orbital determined rod are distributed in the four directions of the deformation body at fixed angles. The orbital determined power-off protection spring has the advantages of being long in service life and good in stability and efficiency.
Description
Technical field
The present invention relates to a kind of orbit determination power-off protection spring.
Background technology
Relay can be used the less larger electric current of Current Control, plays a part automatic adjusting, safeguard protection and change-over circuit in circuit.The kind of relay is a lot; one of them vitals spring is indispensable; spring on relay has played conclusive effect aspect power-off protection; so the stability of spring and validity all must be through strict tests; present power-off protection spring on the market mostly adopts the spring of common shape; when operation, the bad phenomenon such as spring is easy to bend, is shifted, distortion, thus be easy to damage spring.In addition, during due to motion, the active force of spring itself, be very easy to occur break away from or be offset effective service position, so just can't guarantee stability and the validity of spring when power-off protection.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby a kind of long service life is provided, and stability and the good orbit determination power-off protection spring of validity.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of orbit determination power-off protection spring, described spring comprises the distortion main body and is located at the orbit determination bar of distortion on main body, main body is in the shape of a spiral.
As preferably, the orbit determination bar on four orientation of distortion main body, is respectively the first orbit determination bar, the second orbit determination bar, the 3rd orbit determination bar and the 4th orbit determination bar with the angular distribution of fixing.
As preferably, described the first orbit determination bar and the 3rd orbit determination bar are on same center line, and the second orbit determination bar and the 4th orbit determination bar are on same center line.
As preferably, described the first orbit determination bar, the second orbit determination bar, the 3rd orbit determination bar are identical with the height of the 4th orbit determination bar.
As preferably, the height of described distortion main body equals the height of orbit determination bar.
As preferably, described main body is comprised of along the outside spiral extension of same center line by same ratio more than one spiral circle body.
As preferably, described spiral circle body is circular.
As preferably, the diameter of each round screw thread circle body is all identical.
The present invention is owing to being provided with the orbit determination bar; allow the distortion main body of power-off protection spring when operation; can be according to fixing orbiting motion; the bad phenomenon such as contingent bending, displacement while effectively having avoided motion; reduce friction and the consume of power-off protection spring itself, thereby increased useful life, and owing to having fixed movement locus; guaranteed that the power-off protection spring, always in effective job position, has significantly promoted stability and the validity of power-off protection spring.
The accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The front view that Fig. 1 is a kind of orbit determination power-off protection of the present invention spring;
The vertical view that Fig. 2 is a kind of orbit determination power-off protection of the present invention spring.
In figure: 1, distortion main body; 2, orbit determination bar; 20, the first orbit determination bar; 21, the second orbit determination bar; 22, the 3rd orbit determination bar; 23, the 4th orbit determination bar.
Embodiment
Below describe embodiments of the invention in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label means same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be done broad understanding, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be directly to be connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
As shown in Figure 1 to Figure 2, a kind of orbit determination power-off protection spring, comprise distortion main body 1, and be arranged on the orbit determination bar 2 on distortion main body 1, described distortion main body 1 in the shape of a spiral, is comprised of along the outside spiral extension of same center line by same ratio more than one spiral circle body, and described spiral circle body is circular, and the diameter of each round screw thread circle body is all identical, described orbit determination bar 2 with the angular distribution of fixing on four orientation of distortion main body 1, interact, make to be out of shape main body 1 by fixing orbiting motion, can not find because of stressed size bending, the bad phenomenon of displacement, and can guarantee that spring is always in effective job position, stability and the validity of spring have so just significantly been promoted, comprise the first orbit determination bar 20, the second orbit determination bar 21, the 3rd orbit determination bar 22 and the 4th orbit determination bar 23, described the first orbit determination bar 20 and the 3rd orbit determination bar 22 are on same center line, the second orbit determination bar 21 and the 4th orbit determination bar 23 are on same center line.
Preferably, described the first orbit determination bar 20, the second orbit determination bar 21, the 3rd orbit determination bar 22 are identical with the height of the 4th orbit determination bar 23, advantageously, the height of described distortion main body 1 equals the height of orbit determination bar 2, because orbit determination power-off protection spring is provided with orbit determination bar 2, allow the distortion main body 1 of power-off protection spring when operation, can be according to fixing orbiting motion, contingent bending while effectively having avoided motion, the bad phenomenon such as displacement, friction and the consume of power-off protection spring itself have been reduced, thereby increased useful life, and owing to having fixed movement locus, guaranteed that the power-off protection spring is always in effective job position, stability and the validity of power-off protection spring have significantly been promoted.
