Description
Technical field
This utility model relates to the structure of blocking of a kind of coiler pre-tightening apparatus.
Background technology
Coiler pre-tightening apparatus is a kind of protection device being widely used on seat belt, and it includes shell, drive plate, pipe
Road, gas generator, the ball be located in pipeline, pipeline tapping position alignment drive plate, when collision scenario, gas occurs
Device is ignited, and the gas that blast produces expands against rapidly ball in pipeline and moves toward opening part, and ball touches drive plate also after flying out
Drive it to rotate, thus the ribbon (i.e. seat belt) realizing being wrapped in drive disk axles reclaims rapidly, makes member be drawn by seat belt
The most on the seat.Existing this structure exists, and ball may strike the opening part impact of shell bounce-back return pipe road in the meeting that flies out
Other balls fly out the situation causing coiler pre-tightening apparatus normally to work.
Summary of the invention
This utility model recoils to pipeline tapping mainly solving the technical problems that provide one to prevent ball from touching shell
The structure of blocking of coiler pre-tightening apparatus.
Utility model purpose of the present utility model is realized by below scheme: the knot of blocking of a kind of coiler pre-tightening apparatus
Structure, it includes that pipeline, pipeline include that flat extension, flat extension one end are connected with pipeline tapping position and fly out towards ball
Direction extend；Wherein, described flat extension is provided with non-return device；Described non-return device prolongs pipeline tapping to straight for ball
Extension direction flies out, and non-return device stops ball reversely to fly back to pipeline.
Adopt the structure, flat extension set up a non-return device, non-return device without limitation on ball along pipeline
Opening flies out to flat extension direction；Non-return device can stop that ball reversely flies back to pipeline, compared with prior art carries
The stability of high coiler pre-tightening apparatus can normally work.
Wherein, non-return device include unidirectional elasticity can opening and closing opening, described unidirectional elasticity can opening and closing opening its be smaller in size than
Sphere diameter；Ball prolongs and clashes into unidirectional elasticity when pipeline flies out to the outer direction of pipeline and it can be made to open rear ball fly out by opening and closing opening.
So-called unidirectional elasticity can refer to ball and move to this along pipeline tapping to flat extension direction by opening and closing opening
During opening part, this opening can be strutted ball can normally be flown out.When ball reversely flies back, it cannot make this opening open,
So club is blocked in this open outside.
Wherein, non-return device includes base plate and the biside plate being connected with base plate, and base plate is fixed with flat extension, both sides
Plate is that gap is arranged；It is equipped with the bending part towards gap bending on biside plate, is formed at the minimum gap location of two bending parts
Unidirectional elasticity can opening and closing opening.
Wherein, the upper surface of base plate is affixed with the lower surface of flat extension, and flat extension part is arranged in biside plate
Between, bending part stretches in the upper surface of flat extension.
Adopt the structure, the stability between non-return device and flat extension can be increased, due to two bending parts
Stress point is positioned at the top (i.e. at bending part) of flat extension, and the position that non-return device and flat extension are fixed is straight
On the lower surface of extension and left and right both ends of the surface, so stress point does not interferes with the fixing of non-return device.
Wherein, non-return device also includes the front side board being connected with base plate, and front side board is affixed with the leading flank of flat extension.
This kind of structure increases the stability of non-return device further.
Wherein, described bending part is in the terminal position of side plate.
Wherein, the included angle A interval between bending part and side plate is 110 °-130 °.
Wherein, the minimum clearance of two bending parts is more than the radius of a ball.
Wherein, the material of non-return device is rustless steel.
Wherein, the thickness of described bending part is 0.1mm-0.2mm.
Use this structure, utilize the non-return device that rustless steel is made, bending part thickness to be arranged on 0.1mm-0.2mm, it is considered to
Bending part to this kind of thickness has stronger elasticity, and after beneficially ball flies out, bending part carries out return.
The beneficial effects of the utility model: due to the setting of non-return device, can limit ball and fly back to pipeline tapping shadow
Ring remaining ball；And because of the setting without non-return device in prior art, its ball can only use aluminum ball, and reason is that steel ball more holds
Easily bounce-back；And the application can be with steel ball due to the material arranging its ball of non-return device.The aluminum ball of same quality size and steel ball
Comparing it, to carry kinetic energy less, the speed that the speed that aluminum ball promotes drive plate to rotate promotes drive plate to rotate less than steel ball, steel ball
The speed promoting drive plate is far longer than aluminum ball and promotes the speed of drive plate, so arranging in its precaution device due to non-return device
The ball in portion can use steel ball.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail:
Embodiment 1:
Referring to the drawings shown in 1-4, the structure of blocking of a kind of coiler pre-tightening apparatus, it includes pipeline 1 and non-return device
2。
Pipeline 1 includes aperture position 11, and the ball that this aperture position 11 is available in pipeline flies out.Flat extension 12 is pipeline
The part of 1, flat extension 12 is located at aperture position 11 and is extended along the direction that ball flies out.
Non-return device 2 includes 21, two side plates 22 of base plate and front side board 23, and two side plates 22 are divided into the two of base plate 21
Side is that gap is arranged.The lower surface of flat extension 12 is affixed with the upper surface of base plate 21, and flat extension 12 part is fastened on
Between two side plates 22, so so that flat extension 12 coordinates stable with non-return device 2.Stable in order to improve further
Property, front side board 23 is affixed with the leading flank of flat extension 12.
Being respectively provided with bending part 24 on two side plates 22, this bending part 24 is towards the bending of position, gap, and bending part
And the included angle A between side plate 22 is 120 °.The minimum clearance of two bending parts 24 is less than sphere diameter and is more than the radius of a ball, and therefore this is
Formed at small clearance position unidirectional elasticity can opening and closing opening 25, when ball flies out along aperture position 11 towards flat extension 12 direction
Time, ball can strike and make unidirectional elasticity to open by opening and closing opening on two bending parts 24, and ball can pass through unidirectional bullet
Property can opening and closing opening 25.And during adverse movement ball cannot through unidirectional elasticity can opening and closing opening, therefore can be blocked in outside.Bending
The thickness in portion 24 is 0.15mm, and the material of non-return device 2 is rustless steel, so, the bending part 24 of this kind of thickness and angle has
Flexible, after ball flies out, bending part 24 can reset.
