Cross base and pass to tooth and alveolar bone, to expand the width and length of upper mandibular dental arch.As the species for expanding bow device is more and more, people
Selection requirement it is also increasingly stricter, mainly improved at present towards the direction such as material and quality.
Find to expand bow device during practical application after expanding, because jawbone bends the result of device reaction force to expanding, lead
Screw rod is caused often to turn round, bending expansion, effect is undesirable, and what is even circled round sometimes is larger, plays negative effect on the contrary
Fruit, adjust again, without benchmark, can not accurate judgement this to expand the degree and distance of bow.
Although occurring the anti-convolution of sub-fraction at present expands bow device, use is similar to click structure, or uses
Part location structure is positioned, but this kind of apparatus on the one hand cause it is complicated, be easily damaged；On the other hand itself apparatus
On can have more some and influence the part of teeth closure, application that cannot be actual.
The content of the invention
For the problems of in the prior art, bow device is expanded in the anti-convolution of one kind provided by the utility model, by spacing
Hole and plunger realize expansion bow device and can only moved to a direction, avoid the occurrence of screw rod circles round.
To achieve these goals, the technical solution adopted in the utility model is as follows：Bow device, including spiral shell are expanded in a kind of anti-convolution
Bar and two bases, the screw rod both ends are threaded with base respectively, and the screw rod is provided with the threaded hole of twisting screw rod, institute
State to be provided with the outside of base and expand bow device, the screw rod both sides are provided with slide bar, and the slide bar both ends are slidably connected base and to base respectively
Hold in the palm limition orientation.
As preferable technical scheme, position corresponding with slide bar is provided with plunger hole on the base, in the plunger hole
Resilient plunger is located.
As preferable technical scheme, described plunger hole one end is provided with screw, and screw bottom is provided with resilient plunger.
As preferable technical scheme, the resilient plunger is set to the plunger that bottom carries spring.
As preferable technical scheme, the slide bar is provided with some limition orientation holes, and limition orientation hole one end is set
There is abrupt slope, the limition orientation hole other end is provided with gentle slope, and the gentle slope is located at the glide direction of base.
As preferable technical scheme, the width in the limition orientation hole is more than the width of resilient plunger, described spacing to lead
It is less than the half of resilient plunger length to the depth in hole.
As preferable technical scheme, the Flexible change amount of the resilient plunger is more than the depth in limition orientation hole.
The utility model is beneficial in that：
1. the utility model is simple in construction, it can prevent jawbone from causing to expanding bow device reaction force using elastic spacing structure
Screw rod is turned round, and the degree of accuracy of bow is expanded in lifting.
2. resilient plunger is easy for installation, rotary screw band moving base, which slides, just can realize automatic spacing, simple to operate.
3. limition orientation hole one end is provided with abrupt slope, the other end is provided with gentle slope, only carries out spacing, another side to single direction
Just it can deviate to slightly force resilient plunger.
4. limition orientation hole adjusts step by step when being arranged such that expansion bow device adjustment, avoid and disposably adjust excessive ask
Topic.

Embodiment
For the ease of it will be appreciated by those skilled in the art that being further described below in conjunction with the accompanying drawings to the utility model.
As shown in figure 1, bow device, including screw rod 2 and two bases 1 are expanded in a kind of anti-convolution, two outsides of base 1 connect respectively
There is expansion bow device 4, the both ends of screw rod 2 are threaded with base 1 respectively, and screw rod 2 is provided with the threaded hole 5 of twisting screw rod 2, passes through twisting
2 two bases 1 of screw rod can be provided with slide bar 3 in move toward one another, the both sides of screw rod 2 simultaneously, and the both ends of slide bar 3 are slidably connected base 1 simultaneously respectively
To the limition orientation of base 1.
As shown in Fig. 2 being provided with plunger hole with 3 corresponding position of slide bar on the utility model base 1, it is located in plunger hole
Resilient plunger 9, resilient plunger 9 are set to the plunger that bottom carries spring 8, and plunger hole one end positions provided with screw 7, spring 8 it is another
The bottom of one end attachment screw 7.
As shown in figure 3, the utility model slide bar 3 is provided with some limition orientation holes 6, the one end of limition orientation hole 6 is provided with steep
Slope, the other end of limition orientation hole 6 are provided with gentle slope, and gentle slope is located at the distance between the glide direction of base 1, limition orientation hole 6 root
According to doctor's advice Reasonable Regulation And Control.The width in limition orientation hole 6 is more than the width of resilient plunger 9, and the depth in limition orientation hole 6 is less than elasticity
The half of the length of plunger 9, the Flexible change amount of resilient plunger 9 are more than the depth in limition orientation hole 6, ensure that resilient plunger 9 can
Good location.
When in use, screw rod 2 is rotated by threaded hole 5, two bases 1 in left and right is moved respectively to both sides by screw rod 2,
The distance between bow device 4 is expanded in increase, adjusts excessive, the method by debugging step by step to prevent from expanding the distance between bow device 4, directly
The demand for meeting patient to the distance for expanding bow device 4 is stopped the rotation, and now resilient plunger 9 enters limition orientation hole 6, passes through slide bar
3 carry out guide-localization to base 1 respectively, although in the case where jawbone is to expanding the bow reaction of device 4, screw rod 2 has the trend of revolution, base
Support 1 is firmly fixed on the convolution that screw rod 2 is prevented on slide bar 3 by resilient plunger 9.
