Abstract
The utility model relates to a fast-assembly connector for an automobile fuel system, which comprises a first external connection piece and a second external connection piece, wherein a connector is arranged at one end of the first external connection piece, an opening is formed at the other end of the first external connection piece, and a cavity formed inside the first external connection piece is communicated with the connector and the opening; the second external connection piece is in sleeve joint with the inner part of the cavity through the opening end of the first external connection piece; the fast-assembly connector has the improvement that one end of the second external connection piece where the slipped end part is arranged is in sleeve joint with the first external connection piece, and a convex edge is formed around the rear part of the slipped end part; an elastic claw is arranged in the cavity of the first external connection piece at the opening end; and an inside cavity of the elastic claw corresponds to a slipped section of the first external connection piece. The fast-assembly connector has the benefits that the connection method that the first external connection piece is in sleeve joint with the second external connection piece in an embedded way is adopted; the elastic claw arranged on the first external connection piece is matched with the convex edge formed on the second external connection piece so as to achieve quick disassembly and assembly; and the slipped end part of the second external connection piece is matched with the slipped section and a seal ring in the cavity of the first external connection piece so as to further ensure the reliability and the leak tightness of the connection of the first external connection piece and the second external connection piece.
Description
[technical field]
The utility model relates to the automotive oil pipeline connector, refers in particular to vehicle fuel system ready-packaged joint.
[background technique]
Existing automotive oil pipeline connector normally adopts an oil pipe to connect first external piece and second external piece, and after connecting, oil pipe also needs to lock with snap ring, inconvenience and consuming time is installed, and maintenance when it come to just need be laid down the two ends snap ring respectively and takes down tubing maintenance work again and just can carry out in addition.Yet in motor vehicle repair, in case part after breaking down, often all can relate to this class action of maintenance dismounting joint, so the very inconvenience that the oil circuit street corner of existing structure just shows.
[summary of the invention]
The purpose of this utility model is to have overcome above-mentioned defective, and a kind of vehicle fuel system ready-packaged joint of easy accessibility is provided.
The purpose of this utility model is achieved in that a kind of vehicle fuel system ready-packaged joint, it comprises first external piece and second external piece, described first external piece, one end is provided with joint, the other end is provided with opening, in first external piece, be formed with cavity UNICOM joint and opening, described second external piece is socketed in its cavity by the first external piece opening end, its improvements are: described second external piece is provided with in an end of socket first external piece and slips the end, is provided with a circle convex edge after slipping the end; Described first external piece is provided with elastic card claw in the cavity of opening end, the section of slipping of corresponding first external piece of the inboard cavity of elastic card claw;
In the said structure, the section of slipping of cavity is slipped the end with second external piece and is become the drive fit socket in described first external piece;
In the said structure, be provided with seal ring in the section of slipping of cavity in described first external piece;
In the said structure, be arranged at intervals with two seal rings in described first external piece in the section of slipping of cavity at least;
In the said structure, positioning ring is set in the middle of the seal ring of cavity and the elastic card claw in described first external piece;
In the said structure, described elastic card claw comprises an annular shell fragment, and annular shell fragment left and right side stretches out and is formed with boss, and annular shell fragment upper and lower sides extends internally and is formed with overhead kick card post; The first external piece sidewall is provided with through hole in opening end, and described annular shell fragment is arranged in the opening end cavity and its left and right side boss is embedded in the through hole.
Than common vehicle fuel system ready-packaged joint, the beneficial effects of the utility model have been to adopt first external piece, the embedded Placement of the second external piece socket, the elastic card claw that is provided with in first external piece cooperates with the convex edge of second external piece has realized the fast assembling-disassembling that both are connected, and the end of slipping of second external piece cooperates with the section of slipping, seal ring in the first external piece cavity and has more guaranteed both connection reliability and sealing, product global reliability, practicability are very strong, are worthy of popularization.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail

[embodiment]
Below in conjunction with accompanying drawing the utility model specific embodiment is described in detail.
As Figure 1-3, the utility model relates to a kind of vehicle fuel system ready-packaged joint, and it comprises that an end of first external piece 1 and second external piece, 6, the first external pieces 1 is a joint 101, the other end is provided with opening 102, is formed with cavity 103 UNICOM's joints 101, opening 102 in first external piece 1.One end of second external piece 6 is provided with and slips end 601, be provided with a circle convex edge 602 after slipping end 601, corresponding is provided with the section of slipping 104 at first external piece 1 in the cavity 103 of opening end 102, be provided with seal ring 2 in the section of slipping 104, preferable should be provided with at least two seal rings 2, and 2 of two seal rings are provided with separation circle 3 at interval.Between seal ring 2 and the elastic card claw 4 positioning ring 5 is set, prevents seal ring 2 outside slippages.Second external piece, 6 one ends slips end 601 and can be socketed in the section of slipping 104 of first external piece, 1 cavity 103 thus, and under seal ring 2 effects, guarantee both drive fits, thereby guaranteed the connection reliability and the anti-leakage of first external piece 1 and second external piece 6.
First external piece, 1 sidewall is provided with through hole 105 in opening end 102, cavity 103 is the section of slipping 104 outsides of cavity 103 (promptly) flexible claw 4 of embedded fixing in opening end 102 places, elastic card claw 4 comprises an annular shell fragment, annular shell fragment left and right side stretches out and is formed with boss 401, annular shell fragment upper and lower sides extends internally and is formed with overhead kick card post 402, after elastic card claw 4 was placed into cavity 103 by opening end 102, the boss of its both sides promptly can be rabbeted can be from the outside by the button of pinching as two in the through hole 105 of first external piece, 1 sidewall thus.When second external piece 6 slips after end 601 wears in first external piece, 1 cavity 103, overhead kick card post 402 is snapped on the convex edge 602 after second external piece 6 slips end 601, form and connect the location, when dismantling, need only need to press the boss 401 of elastic card claw 4 in first external piece, 1 through hole 105, the spacing that deformation drives two overhead kick card posts 402 promptly can take place and become big in the annular shell fragment, and then release is to the fixing of first external piece 1, first external piece 1 can directly be extracted out and finish dismantlement work, and is very convenient quick.
