Abstract
The utility model discloses a cooling water pipe quick connecting device comprising a pipe connector, a mounting hole and a seal ring. The pipe connector is inserted in the mounting hole, and a groove is formed on the pipe connector. The seal ring is arranged in the groove between the mounting hole and the pipe connector. The groove comprises a straight groove bottom and a first side wall and a second side wall which are located on two sides of the the groove bottom. The first side wall is a curved face connected with a pipe port, and the second side wall is vertical to the axial direction of a pipe of the pipe connector. By the aid of the cooling water pipe quick connecting device, fill rate is increased, and better positioning and sealing effect is produced; meanwhile, structure is simple, producing and assembling are facilitated, and service life of the seal ring is prolonged.
Description
Technical field
The utility model relates to a kind of pipe tipping to be put, and is specifically related to a kind of automobile engine cooling water pipe quick inserting joint device.
Background technique
Utilize the sealing configuration of groove fitted seal circle during metallic water pipe connects, can play easy to connect, the reliable sealing effect.This kind quick inserting joint of metal tube adopts simple rectangle or arcuate furrow more in the engine-cooling system at present, and such structure can't limit the position of seal ring fully, and there is the possibility that moves radially in seal ring, and can't reach good sealing effect.
Summary of the invention:
The technical problems to be solved in the utility model provides a kind of water-cooling tube quick inserting joint device, forms three sealing surfaces between seal ring and pipe joint, produces radial seal simultaneously, and has strengthened fill factor.
In order to solve the problems of the technologies described above the technical solution of the utility model be: a kind of water-cooling tube quick inserting joint device, comprise pipe joint, mounting hole and seal ring, pipe joint inserts mounting hole, and pipe joint is provided with groove, and seal ring places between the groove of mounting hole and pipe joint.Groove comprises straight shape bottom land and is positioned at the first side wall and second sidewall of straight shape bottom land both sides; Described the first side wall is curved surface, is connected with the mouth of pipe; Second sidewall is vertical with the axial direction of pipe joint body.
Seal ring is the O RunddichtringO.
Opening at mounting hole is provided with chamfering.The opening of mounting hole scratches seal ring in the time of can avoiding installing like this.
Adopt such structure that following some benefit is arranged: the compressibility of seal ring is low than general arcuate furrow structure, under lower compressibility, not only is conducive to assembling, can also prolong the working life of seal ring; Simultaneously common property has been given birth to three sealing surfaces between the interior edge face of seal ring and pipe joint exterior edge face and mounting hole, comprises between the bottom land of seal ring and groove, between seal ring and second sidewall and between the interior edge face of seal ring and mounting hole; Other second sidewall better defines the axial position of seal ring.Above structure can improve fill factor, produce better location and sealing effect.Simultaneously simple in structure, the manufacturing assembling is easy, has prolonged the working life of seal ring.

Embodiment
Mode of execution of the present utility model as depicted in figs. 1 and 2 as can be known, a kind of water-cooling tube quick inserting joint device of the present utility model, comprise pipe joint 1, mounting hole 3 and seal ring 2, pipe joint 1 inserts mounting hole 3, pipe joint 1 is provided with groove 1.1, seal ring 2 places between the groove 1.1 of mounting hole 3 and pipe joint 1, and groove 1.1 comprises straight shape bottom land 1.12 and is positioned at the first side wall 1.11 and second sidewall 1.13 of straight shape bottom land 1.12 both sides; The first side wall 1.11 is curved surface, is connected with the mouth of pipe 1.2; Second sidewall 1.13 is vertical with the axial direction of pipe joint 1 body 1.3.
Second sidewall 1.13 defines the axial position of seal ring 2; Simultaneously common property has been given birth to three sealing surface A between the interior edge face of seal ring 2 and pipe joint 1 exterior edge face and mounting hole 3, comprises between seal ring 2 and the bottom land 1.12, between seal ring 2 and second sidewall 1.13 and between the interior edge face of seal ring 2 and mounting hole 3.
Described seal ring 2 is the O RunddichtringO.
Opening at mounting hole 3 is provided with chamfering 3.1, and the opening of mounting hole 3 scratches seal ring 2 in the time of can avoiding installing like this.
Above structure can realize bigger fill factor with the sealing ring material with amount; The compressibility of seal ring is lower, is beneficial to assembling, can also prolong the working life of seal ring; Multi-sealing surface can produce better sealing and locating effect.Water-cooling tube quick inserting joint of the present utility model is simple in structure, and the manufacturing assembling is easy.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
