Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of pressurized seal formula rubber air spring, packet
Air bag 1 is included, the upper end of air bag 1 is integrally formed with snap ring 8, and the inside of snap ring 8 is uniformly provided with cavity 11,11 inner sidewall of cavity
Outside is welded with telescopic mast 13, and snap ring 8 is internally embedded coupled logical hose 9, and the upper end of 9 inner cavity of hose is connected with list
To valve 10, and the right end of hose 9, integrally formed with inserting groove 19, telescopic mast 13 is also to be made using rubber, on the market often
The foldable telescopic column seen, export-oriented similar to bellows, unidirectional valve 10 can make the air pressure inside multiple telescopic masts 13
State is relatively independent, when some in multiple telescopic masts 13 is worn, does not interfere with the connection shape of other telescopic masts 13
State.
Specifically, the upper and lower ends of 1 lateral wall of air bag are connected with flange ring 2, the outer surface of flange ring 2 one at
Type has bolt 4, and the outside of flange ring 2 is closely fitted with capping 3, and bolt 4 runs through the edge of capping 3, and the upper end spiral shell of bolt 4
It is connected to nut 5, the inside for covering 3 offers annular groove 7, and snap ring 8 is connected in annular groove 7, and the inner sidewall of annular groove 7 is uniformly opened
Equipped with the card slot 16 for being located at 11 inside of cavity, the side wall for covering 3 has been embedded in conduit 17, and the inner sidewall of capping 3 is uniformly integrated
The bolt 18 for being socketed on 17 outside of conduit is formed, bolt 18 is plugged in inserting groove 19, and hose 9 is connected with conduit 17, envelope
The intake valve 20 being connected with conduit 17 is bolted in the middle part of 3 inner sidewall of lid, intake valve 20 is the one-way air inlet for producing inspection on the market
Valve, air can only to be filled with inside capping 3 and snap ring 8 and cannot adverse current, guarantee that fit structure based on snap ring 8 only can
Become stronger with the increase of pressure.
Specifically, the inside of 11 inner sidewall of cavity, integrally formed with rubber membrane 12, the right end of telescopic mast 13 offers recessed
Slot 14, the inside of groove 14 are fixedly connected with pricker 15, and the initial length of telescopic mast 13 is slightly longer than the depth of cavity 11, air bullet
When spring is not used, telescopic mast 13 can be in slight shrinkage state by the pressure of rubber membrane 12, and rubber membrane 12 is close to fracture-critical
Value, when air spring uses, telescopic mast 13 is extended by gas pressure after inner inflatable, telescopic mast 13 under air pressure thrust with
When rubber membrane 12 squeezes, the end meeting deformation of telescopic mast 13, middle part is gradually raised, the pricker 15 in groove 14 is ejected, pricker
15 puncture rubber membrane 12, and telescopic mast 13 pops up the inside for protruding into card slot 16, are in clamped condition, and after being popped up due to telescopic mast 13,
The end of telescopic mast 13 can stretch out air 11, therefore clamped condition is irreversible.
Specifically, being connected with girdle ring 6 in the middle part of 1 outer surface of air bag.
Specifically, the middle part of upper enclosure 3 offers aeration aperture 21, the aeration aperture knot with the bellows type air spring of active service
Structure is identical.
Specifically, lower part covers the buffer stopper 22 being pasted in the middle part of 3 inner surfaces positioned at 20 outside of intake valve, in air bag
1 because impact it is too strong due to rupture when, bumper post 22 can play buffering effect.
Working principle: when the utility model is used, the air spring when being assembled, compared to existing air
Spring, it should be noted that for snap ring 8 when being embedded in annular groove 7, cavity 11 needs to be aligned the position of card slot 16, and bolt 18 needs to be directed at grafting
The position of slot 19, remaining assemble flow with now still in the bellows type air spring used it is identical, complete after assembly from aeration aperture 21
It is inflated into air bag 1, under the action of 20 one-way ventilating effect of intake valve, the air pressure in telescopic mast 13 can be more than or equal to gas always
Air pressure in capsule 1, after completing inflation, telescopic mast 13 can pop up under gas pressure, snap fit onto card slot 16, in air spring
When by biggish pressure, under the action of intake valve 20 and unidirectional valve 10, the air pressure inside telescopic mast 13 can be increased constantly,
Under the action of hyperbar, the intensity of telescopic mast 13 can be continuously increased, and air bag 1 and the bonding strength of capping 3 can also increase therewith,
It uses 8 tapered surface of snap ring as force structure merely compared to existing spring, there is telescopic mast 13 to mend between snap ring 8 and capping 3
The bonding strength being short of when sufficient magnitude of interference deficiency avoids and is easy the problem of disengaging, this is needing snap ring 8 not in production
Excessive consideration magnitude of interference problem is wanted, magnitude of interference is backward compatible.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
