Referring to Fig.1, the gas support structure for buffering inflator includes:
Gas strut 13；
It is slidably socketed in the inflator sealing-plug 136 on gas strut 13；And
It is connected to the piston 1352 of 13 end of gas strut,
Wherein, piston 1352 is located at the underface of inflator sealing-plug 136, and inflator sealing-plug 136 includes the first sealing
1361 and second sealing 1362, the second sealing 1362 be integrally connected to the lower surface and second of the first sealing 1361
The radius of sealing 1362 less than the first sealing 1361 radius so that the first sealing 1361 and the second sealing
It is formed with sealing shoulder between 1362, is arranged with exterior seal ring 137 on the sealing shoulder.Inflator sealing-plug 136 is by shaped like rubber
Glue elastomeric material is made, and when inflator sealing-plug 136 fills in the opening of buffering inflator, the second sealing 1362 deeply buffers gas
The inside of cylinder simultaneously forms sealing with the inner sidewall of buffering inflator, and the first sealing 1361 is then covered in the opening of buffering inflator
On, to be sealed to the opening.
Further, the inner circumferential of the first sealing 1361 is formed with a circle cross section in the first interior sealing of convex shape structure
Slot is embedded with the first matched inner seal ring 139, the inner circumferential of the first inner seal ring 139 in seal groove in described first
It is contacted with the side continuous elastic of gas strut 13.First inner seal ring 139 is also made of elastic material, and the first inner seal ring
139 hardness is slightly less than inflator sealing-plug 136, soft or hard different using seal groove in the first of this convex shape structure and two kinds
Elastic material can make the first inner seal ring 139 be embedded in first in seal groove by stabilization, and in first that the material is soft
Sealing ring 139 is while keeping leakproofness with gas strut 13, moreover it is possible to reduce the extruding force that gas strut 13 is subject to, improve gas strut
13 durability.
Further, the inner circumferential of the second sealing 1362 is formed with the second seal groove, and second seal groove is located at described
In first immediately below seal groove, be embedded with the second sealing ring 138 in second seal groove, the inner circumferential of the second sealing ring 138 with
The side continuous elastic of gas strut 13 contacts.Second sealing ring 138 further improves between gas strut 13 and inflator sealing-plug 136
Leakproofness.
Referring again to Fig. 1, the inner circumferential of the second sealing 1362 is embedded with rigid seal bushing 1371, rigid seal bushing
1371 inner circumferential and the side of gas strut 13 are kept in contact.Since inflator sealing-plug 136 has certain height, elastic material system
At inflator sealing-plug 136 and rigid material made of contact area is big between gas strut 13, frictional force is big, be easy to cause gas to support
Bar 13 reciprocatingly slides unsmooth in inflator sealing-plug 136, and friction is small between rigid material, is conducive to improve gas strut
13 smooth degrees to reciprocatingly slide.
Further, the end of gas strut 13 is connected with plunger piston connector 135, the outer Monday of piston connector 135
Be formed with to body formula the carrier 1351 that a circle extends horizontally outward, piston 1352 be sheathed on piston connector 135 at least and by
Carrier 1351 is accepted.
Further, the surface of piston 1352, be bolted with tightening nut 1363, tightening nut on piston connector 135
1363 and piston 1352 upper surface and carrier 1351 and the lower surface of piston 1352 between be equipped with spring leaf 1354.To make
Piston 1352 is tightened nut 1363 and screws when being installed on piston connector 135, the offer that spring leaf 1354 can continue
Pretightning force straight up, so that piston 1352 is mounted more to fasten.
Further, the periphery of piston 1352 offers at least one circle shallow slot 1353, so that the periphery of piston 1352
It is formed at least two panels sealing lip.The design of multiple sealing lips, so that piston 1352 can reduce while guaranteeing leakproofness
The contact area of piston 1352 and buffering cylinder inner wall, further improves the smoothness that gas strut 13 reciprocatingly slides.
Referring again to Fig. 1, the elastic core element extended along its length 134 is embedded with inside gas strut 13, elasticity
The end of core 134 is in end that is coniform and not protruding from gas strut 13, is formed on piston connector 135 and flexible core
The apical lateral of the groove that the end of body 134 matches, piston connector 135 is screwed in from the end of gas strut 13, so that
Piston connector 135 is by the end bolt of the groove and elastic core element 134, and the apical lateral of piston connector 135
With 13 bolt of gas strut.Using the connection type of this inside and outside bolt connection type, on the one hand improves piston connector 135 and gas supports
On the other hand the stability that bar 13 connects also improves the convenience of the dismounting of piston connector 135.
Number of devices and treatment scale described herein are the explanations for simplifying the utility model.To the utility model
Application, modifications and variations will be readily apparent to persons skilled in the art.
Although the embodiments of the present invention have been disclosed as above, it is not limited in institute in specification and embodiments
Column use, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, can
Easily realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, this is practical
It is novel to be not limited to specific details and legend shown and described herein.
