Abstract
The invention discloses a kind of open-types to correct tension spring, hook portion including intermediate elastic part and both ends, the hook portion is mounted in the elastic part, the elastic part is alternately made of several section spiral lines and several segments bending line, the outermost end endpoint of all bending lines positioned at left side and spacing between the outermost end endpoint of the corresponding bending line on right side are equal, form the breach that can be included in middleware;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
Technical field
The present invention relates to auxiliary tools used in a kind of operation on oral cavity;Specifically a kind of open-type corrects tension spring.
Background technique
Most springs require to be fixed on a middleware, and middleware is bar, line or set etc., and spring is made to work
When, there can be a guiding, and not easy to fall off;This structure generally uses in the industry.
In dentistry, intermediate bar is to be generally arch wire or casing;After the tooth being corrected is subjected to displacement, originally fit
The pulling force of conjunction can become smaller, and the spring for generating pulling force just needs to be adjusted, and existing spring adjustment mode is more time-consuming, preceding
It can also directly be truncated in the oral cavity several times or to spring local deformation, arch wire apparatus for correcting will be removed within every one or two months, so
Replace spring again afterwards.
Summary of the invention
The present invention in view of the shortcomings of the prior art, provide one kind can be according to pulling force needs, in the item for not removing whole devices
Under part, a kind of open-type that can freely replace halfway corrects tension spring.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of open-type correction drawing
Spring, the hook portion including intermediate elastic part and both ends, the hook portion are mounted in the elastic part, if the elastic part by
Dry section spiral line and several segments bending line alternately form, and the outermost end endpoint of all bending lines positioned at left side and are located at right
Spacing between the outermost end endpoint of the corresponding bending line of side is equal, and forming one can be included in splitting for middleware
Mouthful.
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.
The line of the outermost end endpoint of all bending lines positioned at left side is helically linear by middle line of axis, owns
Line positioned at the outermost end endpoint of the bending line on right side is helically linear by middle line of axis, the breach helically line
Shape.
The bending line is V-shaped, U-shaped or front end are linearly.
The hook portion is thin type casting, including foreskin portion and hook portion, the foreskin portion are wrapped in the elastic part.
Foreskin portion complete cycle is wrapped on the end of the elastic part;Or partly enclose the end of elastic part, notch with
Breach is located at same direction.
The hook portion is the intermediate plate for having hole, surrounding closed, or intermediate is hole, the plate of single-open.
It is provided with breach compared with prior art, the present invention having the following beneficial effects:, can use this structure, 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.
Detailed description of the invention
Fig. 1 is the structure chart of inventive embodiments one.
Fig. 2 is the structure chart of inventive embodiments two.
Fig. 3 is the structure chart of inventive embodiments three.
Fig. 4 is the structure chart of inventive embodiments four.
Fig. 5 is the working principle diagram of the embodiment of the present invention.
Fig. 6 is the usage state diagram of the embodiment of the present invention.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing: as shown in figures 1 to 6, mark is such as
Under: elastic part 1, helix 11, bending line 12, outermost end endpoint 13, breach 14, foreskin portion 21, hook portion 22, lacks hook portion 2
Mouth 23, middleware 3.
A kind of open-type correction tension spring, the hook portion 2 including intermediate elastic part 1 and both ends, hook portion is mounted on elastic force
In portion, elastic part is alternately made of multistage helix 11 and multistage bending line 12, the outermost end of all bending lines positioned at left side
Endpoint 13 and spacing between the outermost end endpoint of the corresponding bending line on right side are equal, and forming one can receive
The breach 14 for entering middleware 3, can be convenient disassembly, as shown in Figure 5.
The line of the outermost end endpoint of all bending lines positioned at left side is parallel with axis, all bendings positioned at right side
The line of the outermost end endpoint of line is parallel with axis, and breach is parallel with axis;Bending line is V-shaped, U-shaped or front end are linear
Shape.
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, as shown in Figure 4;Its use state is as shown in fig. 6, there are certain angles with breach in middleware, it is not easy to fall off.
Hook portion is thin type casting, including foreskin portion 21 and hook portion 22, foreskin portion are wrapped in elastic part.Foreskin portion is whole
Week is wrapped on the end of elastic part, as shown in Figure 2;Or the end of elastic part is partly enclose, notch 23 is located at same with breach
Direction, as shown in Figure 1;Hook portion is the intermediate plate for having hole, surrounding closed, or intermediate is hole, the plate of single-open, such as
Shown in Fig. 3 and Fig. 4.
