Description
Technical field
The utility model is related to automobile coiler field of components, and in particular to a kind of coiler pre-pressing structure.
Background technology
Safety belt is made of the synthetic fibers of intensity maximum, the coiler with tool self-locking function, after fastening one's safety belt, volume
Device is received to take up automatically, when vehicle just in case when there is emergency braking, head-on crash or rolling, occupant can make safety belt by
To quick and fierce stretching, the self-locking function of coiler can block safety belt in moment this moment, so that occupant is close to seat, avoid
It falls out outside vehicle or collision is injured.During coiler pre-tightening mechanism preload currently on the market turns limiter, baton round holds when retracting
It is easily blocked with steel pipe nozzle, causes the injury to occupant, stability is poor, and therefore, we design a kind of coiler pre-pressing structure.
Invention content
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of coiler pre-pressing structure, using more
The structure of a steel ball can be connected more smooth during preload turns limiter, improve seat belt retractor and imitated to the protection of occupant
Fruit.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of coiler pre-pressing structure, including steel pipe, are equipped with multiple driving balls in the steel pipe, and the driving ball can be
It is moved along the path of the steel pipe under the action of gas and drives driving wheel；
The row tail of multiple driving balls is set there are one baton round, sets that there are one steel between driving ball described in two of which
Column.
Further, jagged, and the steel is opened up along the steel pipe inner tail of the driving ball motion path
Pipe is arranged along the turning circumference of the driving wheel.
Further, multiple driving balls are uniformly distributed along the path direction of the steel pipe, and the drive of row head
Dynamic ball initial position is close to the notch.
Further, the driving ball is steel ball.
Further, the driving ball is provided with 12.
Further, the both ends of the steel column are circular arc.
Further, the diameter of the diameter of the baton round and the driving ball is respectively less than the diameter of the steel pipe.
Using the above structure, when in use, the driving ball and baton round are under the influence of gas along the road of steel pipe
Diameter moves, and the driving ball contacts with driving wheel in indentation, there and drives driving wheel；The baton round becomes under the pressure of the gas
Shape, sealed steel pipe, so as to improve pressure；For baton round after being contacted with driving wheel when being got in steel pipe, movement locus can not
Control, when having certain risk that can cause the limiter stage, driving wheel is counterclockwise rotary plastic ball is blocked with steel pipe and is caused in limiter value
It rises and increases occupant injury；At this point, when the steel column and driving cog are clamped and effectively prevent baton round from retracting and steel pipe nozzle card
Firmly, force value early period can be avoided to rise the injury increased to occupant, the position of the steel column can be adjusted according to different situations.
To sum up, the beneficial effects of the utility model are：The pre-pressing structure increases steel column between driving ball, can prevent
Baton round blocks when retracting with steel pipe nozzle, and force value rising early period when limiter is caused to increase the injury to occupant, effective to improve
The consistency and stability of product.

Specific implementation mode
It, below will be to the technology of the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
Shown in Fig. 1-Fig. 4, the utility model provides a kind of coiler pre-pressing structure, including steel pipe 1, the steel pipe
Multiple driving balls 3 are equipped in 1, the driving ball 3 can be moved and be driven along the path of the steel pipe 1 under the influence of gas
Driving wheel 5；
The row tail of multiple driving balls 3 is set there are one baton round 2, and the baton round 2 can squeeze under the influence of gas
Compressive strain increases air-tightness, is set between driving ball 3 described in two of which there are one steel column 4, the steel column 4 can prevent plastics
Ball 2 blocks when retracting with 1 nozzle of steel pipe, and early period, force value rose injury of the increase to occupant when causing limiter.
The driving wheel 5 is driven for convenience of driving ball 3, along the 1 inside tail of the steel pipe of driving 3 motion path of ball
Portion opens up jagged 6, and the steel pipe 1 is arranged along the turning circumference of the driving wheel 5.
For can rapid pretension, multiple driving balls 3 are uniformly distributed along the path direction of the steel pipe 1, and row head
3 initial position of driving ball close to the notch 6.
Further, the driving ball 3 is steel ball.
To use the length of steel pipe 1, the driving ball 3 to be provided with 12.
To make steel column 4 block driving wheel 5, the both ends of the steel column 4 are circular arc, and can reduce rubbing between steel pipe
It wipes.
For convenience of the movement of driving ball 3, the diameter of the baton round 2 and the diameter of the driving ball 3 are respectively less than the steel
The diameter of pipe 1.
Using the above structure, when in use, the driving ball 3 and baton round 2 are under the influence of gas along steel pipe 1
Path moves, and the driving ball 3 is in the contact of driving wheel 5 in notch 6 and drives driving wheel 5；Pressure of the baton round 2 in gas
It is deformed under power, sealed steel pipe 1, so as to improve pressure；Baton round 2 when being got in steel pipe 1 with driving wheel 5 after contacting, fortune
Dynamic rail mark is uncontrollable, and when having certain risk that can cause the limiter stage, 5 rotary plastic ball 2 counterclockwise of driving wheel is blocked with steel pipe 1
It causes limiter value to rise and increases occupant injury；At this point, the steel column 4 is clamped with driving cog and effectively prevents baton round 2 from retracting
When blocked with 1 nozzle of steel pipe, force value early period can be avoided to rise and increase injury to occupant, the position of the steel column 4 can basis
Different situations are adjusted.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
