Abstract
The utility model relates to a kind of automobile oil pipe connecting structure of improvement, mainly comprise metallic steel pipe joint, oil return rubber hose coupling, rubber o-ring and spring hoop, described metallic steel pipe joint free end is bore spine shape, described metallic steel pipe joint free end is provided with groove, described rubber o-ring is arranged in described groove, described oil return rubber hose coupling is enclosed within described metallic steel pipe joint, and described oil return rubber hose coupling free end is provided with snap-fit grooves, and described spring hoop is positioned at snap-fit grooves place.Described metallic steel pipe joint free end is bore spine shape, is convenient to metallic steel pipe joint and oil return rubber hose coupling installation assembling; At metallic steel pipe joint and oil return rubber hose coupling, rubber o-ring is set, solve the low temperature leakage problems turning to low pressure fuel pipe joint, increase the pulling-out force of low pressure metal steel pipe joint and low pressure oil return rubber hose coupling simultaneously, and then improve the high pressure resistant reliability turning to low pressure fuel pipe; The design of spring hoop further increases the high pressure resistant reliability turning to low pressure fuel pipe.
Description
Technical field
The utility model relates to technical field of pipeline connection, is specifically related to a kind of automobile oil pipe connecting structure of improvement.
Background technique
At home and abroad, automobile power steering low pressure fuel pipe linkage structure traditional is at present: at low pressure port of steel pipe assembly drum packet mode connecting head, then is connected with low pressure rubber pipe and utilizes clip to clamp; This kind of structure has certain defect:
1. in the winter time low temperature time, especially in the north, when car starts, easily there is seepage in steering system low pressure fuel pipe, reason mainly turns to liquid through the cryogenic freezing at a night, and form becomes solid solution state from liquid state, poor fluidity, thus increase the instantaneous pressure of oil return system, cause low pressure fuel pipe seepage;
2. after hot car, whole steering system can be in the environment of a continuous high temperature, and As time goes on, traditional connection sealing configuration is at high temperature durable seal aspect of performance Shortcomings.
As the improvement of said structure, be process an annular groove at low pressure steel tube connection head near the position of bulge, reinstall O type circle, load onto clip after being finally connected with rubber pipe fastening.
Model utility content
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of stationarity a kind of low pressure steel pipe spin slot that is good, that can realize effective sealing connection to add O type circle linkage structure.
The technical scheme in the invention for solving the above technical problem is:
A kind of automobile oil pipe connecting structure of improvement, mainly comprise metallic steel pipe joint, oil return rubber hose coupling, rubber o-ring and spring hoop, described metallic steel pipe joint free end is bore spine shape, described metallic steel pipe joint free end is provided with groove, described rubber o-ring is arranged in described groove, described oil return rubber hose coupling is enclosed within described metallic steel pipe joint, and described oil return rubber hose coupling free end is provided with snap-fit grooves, and described spring hoop is positioned at snap-fit grooves place.
As optimal way, described metallic steel pipe joint circumferencial direction is provided with boss, and described oil return rubber hose coupling end face contacts with boss.
As optimal way, described snap-fit grooves is between metallic steel pipe joint and rubber o-ring.
The beneficial effects of the utility model are: described metallic steel pipe joint 1 free end is bore spine shape, are convenient to metallic steel pipe joint and oil return rubber hose coupling installation assembling; At metallic steel pipe joint and oil return rubber hose coupling, rubber o-ring is set, solve the low temperature leakage problems turning to low pressure fuel pipe joint, increase the pulling-out force of low pressure metal steel pipe joint and low pressure oil return rubber hose coupling simultaneously, and then improve the high pressure resistant reliability turning to low pressure fuel pipe; The design of spring hoop further increases the high pressure resistant reliability turning to low pressure fuel pipe.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model metallic steel pipe joint structure schematic diagram.
In figure, 1, metallic steel pipe joint, 2, oil return rubber hose coupling, 3, rubber o-ring, 4, spring hoop, 5, boss.
Embodiment
Illustrate that the invention will be further described with specific embodiment below in conjunction with accompanying drawing:
As shown in Figures 1 and 2, a kind of automobile oil pipe connecting structure of improvement, mainly comprise metallic steel pipe joint 1, oil return rubber hose coupling 2, rubber o-ring 3 and spring hoop 4, described metallic steel pipe joint 1 free end is bore spine shape, described metallic steel pipe joint 1 free end is provided with groove, described rubber o-ring 3 is arranged in described groove, described oil return rubber hose coupling 2 is enclosed within described metallic steel pipe joint 1, described oil return rubber hose coupling 2 free end is provided with snap-fit grooves, and described spring hoop 4 is positioned at snap-fit grooves place.Described snap-fit grooves connects rear between rubber o-ring 3 and boss 5 at metallic steel pipe joint 1 and oil rubber hose joint.
As shown in Figure 2, described metallic steel pipe joint 1 circumferencial direction is provided with boss 5, and described oil return rubber hose coupling 2 end face contacts with boss 5.
In using process, described metallic steel pipe joint 1 free end is bore spine shape, is convenient to metallic steel pipe joint 1 and oil return rubber hose coupling 2 installation assembling; At metallic steel pipe joint 1 and oil return rubber hose coupling 2, rubber o-ring 3 is set, solve the low temperature leakage problems turning to low pressure fuel pipe joint, increase the pulling-out force of low pressure metal steel pipe joint 1 and low pressure oil return rubber hose coupling 2 simultaneously, and then improve the high pressure resistant reliability turning to low pressure fuel pipe; The design of spring hoop 4 further increases the high pressure resistant reliability turning to low pressure fuel pipe.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
