Abstract
The utility model belongs to air spring product technical field, specifically discloses a kind of air-spring piston structure, including piston only, and outside wall surface is equipped with non-skid thread at the top port of the piston only, and the non-skid thread is internally provided with reinforcing rib.The air-spring piston structure can not only realize integration with piston only, but also increase the intensity of non-skid thread, improve service life and the safety of product, reduce the production cost of enterprise, reduce workload, simplify installation procedure, working efficiency greatly improves.
Description
Technical field
The utility model belongs to air spring product technical field, more particularly to a kind of air-spring piston structure changes
Into.
Background technology
The non-skid thread of air-spring piston is mostly cylinder thin-wall construction, and leather bag is interference fitted by pressure ring deformation with non-skid thread
When fastening, insufficient strength at anti-skidding cable architecture, when press fitting, easily deforms so that leather bag can not fasten, and lead to leather bag occur
The bad phenomenons such as gas leakage influence air spring service life, reduce performance.
In the prior art, usually increase a support ring in non-skid thread interior wall construction, support ring is with non-skid thread inner wall
Interference fit can increase the intensity of anti-skidding cable architecture, improve leather bag pretightning force, and non-skid thread deforms when solving air spring press fitting
It is excessive, cause the bad phenomenons such as leather bag gas leakage, in order to extend product service life, reinforce product security performance and use the longevity
Life, and reduce support ring and frequently replace, but dismantle, installation it is more difficult, bring inconvenience to user, increase enterprise's manufacture
Cost and employee work amount.
Therefore, a kind of research and development service life that can improve product and safety, reduce the air spring of the production cost of enterprise
Piston structure is extremely urgent.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, disclose a kind of air-spring piston structure, the air
Spring piston structure can not only realize integration with piston only, but also increase the intensity of non-skid thread, improve service life and the peace of product
Quan Xing reduces the production cost of enterprise, reduces workload, simplifies installation procedure, and working efficiency greatly improves.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme：
A kind of air-spring piston structure described in the utility model, including piston only, the top of the piston only
Outside wall surface is equipped with non-skid thread at port, and the non-skid thread is internally provided with reinforcing rib.
As being further improved for above-mentioned technology, the reinforcing rib is that at top, bending is inwardly formed by the non-skid thread.
As the further improvement of above-mentioned technology, the piston only, reinforcing rib are integrated with non-skid thread to be made.
Compared with prior art, the utility model has the beneficial effects that：
(1) non-skid thread is carried out inside bending with shape by air-spring piston structure described in the utility model on its top
At reinforcing rib, the intensity of piston only is effectively improved, and compactness is installed with the cooperation of rubber pneumatic bag, prevent from slipping, improve empty
Service life, security performance and the damping effect of gas spring；
(2) air-spring piston structure described in the utility model, the piston, reinforcing rib are integrated with non-skid thread to be made
It forms, without installation and removal, manufacturing process is simple and convenient, and production process simplifies, and greatlys save cost of manufacture.
Description of the drawings
The utility model is described in detail in the following with reference to the drawings and specific embodiments：
Fig. 1 is air spring constructions schematic diagram described in the utility model；
Fig. 2 is the fit structure schematic diagram of air spring and rubber pneumatic bag described in the utility model.
Specific implementation mode
As shown in Figure 1, a kind of air-spring piston structure described in the utility model, including piston only 1, the piston
Outside wall surface is equipped with non-skid thread 2 at the top port of ontology, and the non-skid thread 2 is internally provided with reinforcing rib 3, as seen from the figure, should add
Strengthening tendons 3 are that at top, bending is inwardly formed by the non-skid thread 2, and the piston only 1, reinforcing rib 3 and non-skid thread 2 are integrated
It is made.
As shown in Fig. 2, when installation, the piston only 1 is deformed by pressure ring 4 and is installed on after the interference fit of non-skid thread 2
On rubber pneumatic bag 5 so that rubber pneumatic bag 5 can be tightly fastened at non-skid thread 2.
A kind of air-spring piston structure described in the utility model can effectively improve rubber pneumatic bag 6 when in use
Pretightning force, effectively prevent air spring press fitting occur in the process non-skid thread deformation, rubber gas gas leakage phenomena such as, extend product make
With the service life, enhance security performance and damping performance.
The utility model is not limited to the above embodiment, and every various changes or modifications to the utility model do not take off
Spirit and scope from the utility model, if these modification and variations belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also implied that comprising these modification and variations.
