Abstract
The utility model relates to the technical field of automobile pipelines and particularly relates to a sealing structure of the automobile pipelines. The sealing structure comprises a cylinder, an O-shaped rubber seal ring, a gasket and a pipe connector, wherein an inserting groove matched with the O-shaped rubber seal ring in size is arranged on the sealing surface of the gasket, the section of the inserting groove is arc-shaped, and the gasket is made of powder metallurgy metal. When the sealing structure is used, sealing performance of braking pipelines, steering pipelines and clutch pipelines can be achieved, and maneuverability, safety and reliability of drivers are greatly improved. In addition, the sealing structure of the automobile pipelines is simple in structure, reasonable in design and low in manufacture cost.
Description
Technical field
The utility model relates to automobile pipeline technical field, particularly a kind of automobile line seal structure.
Background technique
The automobile pipeline mainly is distributed on the chassis of automobile, and it comprises braking line, turns to pipeline, the clutch pipeline, and the end face seal of pipeline design is even more important.The sealability of pipeline directly relates to handling, the Security and the reliability of automobile.If can be from designing the reliability that improves line seal, then can improve driver's handling, Security and reliability greatly.
At present, the line seal design mainly contains two kinds of modes.
A kind of is copper packing sealing, and its directly adds the copper packing sealing on the end face that connector need seal, and it is just passable to be screwed into cylinder body.It simple in structure, easy to use, but the sealing effect of copper packing is bad, oil leakage phenomenon occurs through regular meeting, needs often to change.Add that the copper packing cost is higher relatively, often change and cause expense bigger that also have in store management, copper packing is lost easily, brings unnecessary trouble to management.
Second kind is that the cone copper ring adds " O shape " rubber ring seal, and cover upper cone copper ring adds seal with elastometic washer on connector, and the cross section that the cone copper ring cooperates with seal with elastometic washer is rectangular-shaped.With respect to first kind of seal form; This sealing structure effect is much improved; But the cross section that the cone copper ring cooperates with seal with elastometic washer is rectangular-shaped, and rubber ring is " an O shape ", so both are in the majority for the some contact; Cause rubber seal often to damage easily like this, add that to make awl copper body ring cost also higher.Therefore, how to guarantee the line seal performance, how to provide a kind of simple, economical and practical sealing configuration to become the topic of automobile pipeline industry research.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, provides a kind of simple in structure, a kind of automobile line seal structure reasonable in design, easy to use.
For realizing above-mentioned purpose, the technological scheme that the utility model adopts is:
The described a kind of automobile line seal structure of the utility model; It comprises cylinder body, " O shape " rubber seal, packing ring and connector; Said cylinder body and connector are through being threaded, and said " O shape " rubber seal and packing ring are arranged between cylinder body and the connector.The sealing surface of said packing ring be provided with one with the supporting embedded groove of " O shape " rubber seal size, the cross section of said embedded groove is " circular arc ", the material of said packing ring is a powder metallurgy.
Further, the arc diameter of said " O shape " rubber seal and embedded groove is identical, and said " O shape " diameter of rubber seal is greater than 1～2mm of the embedded groove degree of depth.
After adopting said structure, the utility model beneficial effect is: the described a kind of automobile line seal structure of the utility model, its packing ring are to adopt the powder metallurgy extrusion modling, have increased the rubber seal embedded groove of " circular arc " at the sealing surface of packing ring.When cylinder body and connector screw thread spun, the face of rubber seal and embedded groove made sealing effect reach desirable requirement through mutual extrusion.The good sealing effect of this structure, easy for installation, the powder metallurgy of packing ring has replaced copper product, thereby reduces cost of material.The utlity model has simple in structure, reasonable in design, low cost of manufacture.

Fig. 1 is the sectional structure chart of the utility model;
Fig. 2 is an A place amplification assumption diagram among Fig. 1.
Description of reference numerals:
1, cylinder body; 2, " O shape " rubber seal; 3, packing ring; 31, embedded groove; 4, connector.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2; The described a kind of automobile line seal structure of the utility model; It comprises cylinder body 1, " O shape " rubber seal 2, packing ring 3 and connector 4, and said cylinder body 1 and connector 4 are through being threaded, and said " O shape " rubber seal 2 and packing ring 3 are arranged between cylinder body 1 and the connector 4; It is characterized in that: the sealing surface of said packing ring 3 be provided with one with the supporting embedded groove 31 of " O shape " rubber seal 2 sizes, the cross section of said embedded groove 31 is " circular arc "." O shape " rubber seal 2 is placed in the rubber seal embedded groove 31 during use; When cylinder body 1 and connector 4 screw threads spin; The diameter of " O shape " rubber seal is greater than embedded groove 31 degree of depth; Make " O shape " rubber seal 2 fully stressed through mutual extrusion, " O shape " rubber seal 2 can be filled up the space of cylinder body 1 and connector 4, makes sealing effect better.
The material of said packing ring 3 is a powder metallurgy.Powder metallurgy is all kinds of metal leftover pieces castings, and powder metallurgy has replaced copper material, the saving greatly that obtains from cost.
Said " O shape " rubber seal 2 is identical with the arc diameter of embedded groove 31, and said " O shape " diameter of rubber seal 2 is greater than 1～2mm of embedded groove 31 degree of depth.The sealing effect of " O shape " rubber seal is the most desirable at this moment.
, on the line seal of automobile, solve braking line, turned to pipeline, the sealing of clutch pipeline with the utility model, improved driver's handling, Security and reliability greatly.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
