Description
Technical field
This utility model relates to the fixed structure of a kind of coiler pre-tightening apparatus ball and pipeline.
Background technology
Coiler pre-tightening apparatus is a kind of protection device being widely used on seat belt, and it includes drive plate, pipeline, gas
Body generator, the ball being located in pipeline, the opening alignment drive plate of pipeline, when collision scenario.Gas generator is ignited,
The gas that blast produces expands against rapidly net opening part in pipeline and moves, and ball is touched drive plate after flying out and drives its turn
Dynamic, thus the ribbon (i.e. seat belt) realizing being wrapped in drive disk axles reclaims rapidly, makes member by belt pull at seat
On.Owing to gas generator is at non-explosion time, ball position in pipeline can not change, and (ball position changes that pole has can
Can be able to affect and the coordinating of drive plate), therefore prior art generally arranges an extension on drive plate, and this extension stretches into
The opening part of pipeline props up the ball of first side, but this kind of structure needs can not touch in view of in the extension rotation process of drive plate
Encounter miscellaneous part and otherwise can affect the rotation of spherical zone nutating disk, therefore higher to the processing request of extension in prior art.
Except processing request this problem high, there is also first side ball in prior art installs unstable situation.Therefore one is designed
The structure how making first side ball fixing-stable reduce again processing request is a need for.
Summary of the invention
This utility model is mainly solving the technical problems that provide a kind of simple in construction, install stable coiler pretension dress
Place and the fixed structure of pipeline.
Utility model purpose of the present utility model is realized by below scheme: a kind of coiler pre-tightening apparatus ball and pipeline
Fixed structure, it includes pipeline and ball, and the quantity of ball is several and is located in pipeline, and the ball of first side is positioned at opening of pipeline
Near Kou；Wherein, also including fixture, fixture is located between ball and the duct wall of first side and is fixed with duct wall, the ball of first side
On offer fixing groove, fixture is provided with the portion of strutting；It is tight fit that the described portion of strutting stretches in fixing groove with fixing groove；First side
Move the destruction portion of strutting during ball work to fly out pipeline.
Adopt the structure, due to the design of fixture, can be by strutting when making the ball of first side under non-duty
Portion is fixed on fixture.When the ball work of first side, owing to the ball Impact direction of first side is vertical relation with the portion of strutting, so
The ball of first side can destroy the portion of strutting and fly out from pipeline.Compared with prior art, the fixed structure of the ball of first side must not set
Put on drive plate, reduce processing request, add the stability of first side ball.
Wherein, guide part is positioned at the front side of spherical portion.
Wherein, the bag of first side includes guide part and the spherical portion being connected with guide part, and guide part and spherical portion are offered
There is chute；Fixing groove is opened in bottom chute and is positioned in spherical portion；Fixture is strip piece, and fixture stretches in chute,
The portion of strutting is positioned at the upper surface of fixture, and when the ball of first side moves, slideway againsts fixture upper surface and moves.
Adopt the structure, the ball shape of first side is arranged to spherical portion and is combined with guide part, be conducive to the ball of first side to exist
Motor process forms guiding relation with fixture.
Wherein, described fixture upper surface is provided with inclined-plane boss, and inclined-plane boss is positioned at by guide part, when the ball of first side works
First against fixture to move, the inclined-plane then against inclined-plane boss tilts the pipeline that flies out.
In prior art, ball generally employing level flies out, and may strike coiler pre-tightening apparatus owing to ball level flies out
Housing bounce-back affect other balls, so the design adopted the structure makes ball be to fly out along an inclined-plane when flying out, first subtract
The power that flies out of bead, next avoids ball to occur bounce-back to affect remaining ball.
Wherein, the inclined-plane of inclined-plane boss is 164 °-170 ° with the included angle A of fixture upper surface.Use the oblique of this kind of angle
Face is to draw through substantial amounts of experiment, and the beveling effect in this interval is optimal.
Wherein, the bottom surface of chute includes that cambered surface part, cambered surface part are positioned at the front position of chute bottom surface, when cambered surface part
When moving to the inclined-plane of inclined-plane boss, cambered surface part is tangent with this inclined-plane.
Adopting the structure, owing to the bottom surface of chute is moved along fixture upper surface, its front position uses arc
Face design can reduce impulsive force, prevents the ball of first side from breaking fixture.
Wherein, chute bottom surface include that chamfered portion, chamfered portion are positioned at the front position of chute bottom surface, chamfered portion
Slopes which match with inclined-plane boss.
Wherein, pipeline offering spacing hole, fixture lower surface is provided with location division, location division stretch in spacing hole with
Spacing hole is tight fit.
Adopt the structure, beneficially the installation of fixture.
Wherein, the quantity of location division is two, and one of them is positioned at the lower section in the portion of strutting.
This kind of structure, it is simple to strut coordinating of portion and fixing groove, makes the fixing groove of the portion's of strutting alignment, then profit the most when mounted
The location division being positioned at below the portion of strutting is beaten so that the portion of strutting stretches into formation tight fit in fixing groove with instrument.
Wherein, the material of fixture is POM.
Use the fixture of POM material, main consider that POM hardness is high, can ensure that when ball does not works ball and pipeline it
Between stability.Friendship is there is not owing to strutting the fixed-direction of the Impact direction in portion and fixture and pipeline when ball moves
Fork, so ball can destroy normally opened portion easily and fly out.
The beneficial effects of the utility model: the design of fixture makes the ball of first side more stable with tube fit, and
Owing to the design of fixture can play guide effect.
