Abstract

The utility model discloses a kind of open-type NiTi tension springs, it is formed by single line material bending, hook portion including intermediate elastic part and both ends, the elastic part is alternately made of several section spiral lines and several segments bending line, the breach that can be used for being included in middleware is formed positioned at the bending line in left side and between the bending line on right side, the hook portion and the helix are ipsilateral；The advantage is that: being provided with breach, can use this structure, the application be included in middleware, that is to say, that in the case where not removing middleware, be free to installation, disassembly or replacement 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 utility model relates to auxiliary tools used in a kind of operation on oral cavity；Specifically a kind of open-type NiTi pulling force bullet Spring.

Background technique

In using, often there is a middleware among the tension spring of buckle, middleware can play guide springs The effect in direction.

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

But life also has the occasion for being frequently necessary to replacement 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, directly cutting length or local deformation is used in patient's mouth, so that office Portion is inelastic；Spring is replaced within every one or two months with regard to needing to dismantle whole arch wire apparatus for correcting, it is more inconvenient to operate.

Utility model content

The utility model can not remove whole devices according to pulling force needs in view of the shortcomings of the prior art, providing one kind Under the premise of, a kind of open-type NiTi tension spring that can freely replace halfway.

In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: a kind of open-type nickel Titanium tension spring is formed by single line material bending, and the hook portion including intermediate elastic part and both ends, the elastic part is by several Section spiral line and several segments bending line alternately form, and are formed positioned at the bending line in left side and between the bending line on right side One can be used for being included in the breach of middleware, and the hook portion and the helix are ipsilateral.

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 middle line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by middle 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.

The utility model compared with prior art, has the following beneficial effects: and is provided with breach, can use this structure, The application is included in middleware, that is to say, that in the case where not removing middleware, be free to installation, disassembly or replacement The spring of the application structure, with this come achieve the purpose that adjust pulling force.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing: as shown in figs. 1-7, mark It infuses as follows: 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, the hook including intermediate elastic part 1 and both ends Shape portion 2, elastic part is alternately made of multistage helix 11 and multistage bending line 12, positioned at the bending line in left side and positioned at right side The breach 3 that can be used for being included in middleware 4 is formed between bending line, hook portion is ipsilateral with helix, 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, disassembly or replacement；As shown in working principle Fig. 6.

As optimization, as shown in Figure 1, bending line is in U-shape；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 circle shape, 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 middle line helically line The line of shape, the outermost end endpoint of all bending lines positioned at right side is helically linear by middle line of axis, breach helically line Shape, non-straight shaped opening；It in any direction, is all that a bending line rides on middleware, it is not easy to slide；Such as Fig. 4 and Fig. 7 institute Show.

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