Abstract

The invention discloses a kind of open-type NiTi tension springs, it is formed by single line material bending, include the hook portion of intermediate elastic part and both ends, the elastic part is alternately made of several section spiral lines and several sections of bending lines, a breach that can be used for being included in middleware, the hook portion and the helix homonymy are formed positioned at the bending line in left side and between the bending line on right side；It the advantage is that：Be provided with breach, can utilize this structure, the application is included in middleware, that is to say, that in the case where not removing middleware, be free to installation, dismounting or replace the application structure spring, with this come achieve the purpose that adjust pulling force.

Description

A kind of open-type NiTi tension spring

Technical field

The present invention relates to the auxiliary tools used in a kind of operation on oral cavity；Specifically a kind of open-type NiTi tension spring.

Background technology

In using, for there are one middleware, middleware can play guide springs among the tension spring of buckle The effect in direction.

In general, the spring loaded onto is designed in advance, need not be replaced, and is only just needed in special circumstances in fracture etc. Stripping device is wanted to be replaced.

But life also has the occasion for being frequently necessary to replace spring；In dentistry, when two teeth are by tension spring After furthering, because position becomes close so that the pulling force of tension spring fluffs；So it is suitable to obtain to need regular adjustment spring Pulling force；Existing mode is all：Pliers is used in patient's mouth, directly cuts length or local deformation so that office Portion is inelastic；Spring is replaced with regard to needing to dismantle whole arch wire apparatus for correcting within every one or two months, operation is more inconvenient.

Invention content

The present invention in view of the shortcomings of the prior art, provide one kind can be according to pulling force needs, before not removing whole devices It puts, a kind of open-type NiTi tension spring that can freely replace halfway.

In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of open-type NiTi drawing Power spring is formed by single line material bending, includes the hook portion of intermediate elastic part and both ends, the elastic part is by several sections of spiral shells Spin line and several sections of bending lines alternately form, and are located at the bending line in left side and the formation one between the bending line on right side It can be used for being included in the breach of middleware, the hook portion and the helix homonymy.

The outermost end endpoints of all bending lines positioned at left side and corresponding bending line positioned at right side Spacing between outermost end endpoint is equal.

The line of the outermost end endpoint of all bending lines positioned at left side is parallel with axis, all positioned at right side The line of the outermost end endpoint of the bending line is parallel with axis, and the breach is parallel with axis.

Alternatively, the line of the outermost end endpoint of all bending lines positioned at left side is using axis as center line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by center line of axis, the breach It is helically linear.

The bending line is V-shaped, U-shaped or front end are linearly；The hook portion forming V-shape or C-shaped.

Compared with prior art, the present invention having the advantages that：It is provided with breach, this structure can be utilized, this Middleware is included in application, that is to say, that in the case where not removing middleware, be free to install, dismantle or replace this Shen Please structure spring, with this come achieve the purpose that adjust pulling force.

Specific implementation mode

Present invention is further described in detail with specific implementation mode below in conjunction with the accompanying drawings：As shown in figs. 1-7, it marks such as Under：Elastic part 1, hook portion 2, helix 11, bending line 12, breach 3, outermost end endpoint 13, middleware 4.

A kind of open-type NiTi tension spring is formed by single line material bending, includes the hook of intermediate elastic part 1 and both ends Shape portion 2, elastic part are alternately made of multistage helix 11 and multistage bending line 12, are located at the bending line in left side and positioned at right side A breach 3 that can be used for being included in middleware 4, hook portion and helix homonymy are formed between bending line, to influence to install； The outermost end endpoint of the outermost end endpoint 13 of all bending lines positioned at left side and the corresponding bending line positioned at right side Between spacing it is equal；The line of the outermost end endpoint of all bending lines positioned at left side is parallel with axis, all to be located at the right side The line of the outermost end endpoint of the bending line of side is parallel with axis, and breach is parallel with axis；It is convenient to be realized by breach Installation, dismounting or replacement；As shown in operation principle Fig. 6.

As an optimization, as shown in Figure 1, bending line takes the shape of the letter U；As shown in Fig. 2, bending line is V-shaped；As shown in figure 3, bending line It is V-shaped it is linearly in other words in " " type；Hook portion forming V-shape or C-shaped can also be in cast, as shown in Figure 5.

As deformation：The line of the outermost end endpoint of all bending lines positioned at left side is using axis as center line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by center line of axis, breach helically line Shape, non-straight shaped opening；In any direction, all it is that a bending line rides on middleware, it is not easy to slide；Such as Fig. 4 and Fig. 7 institutes Show.

The application is not limited only in operation on oral cavity equipment, can also be applied in other industrial parts.
