Adopt the utility model discloses, set up two at least joint rings, and the cover is established first sealing washer between adjacent joint ring, further strengthen the connection compactness of quick connector body and connector body.
Description
Technical Field
The utility model relates to a quick connector, especially a fuel pipeline quick connector.
Background
In the connection process of the fuel pipelines, a quick connector is often used, one end of the quick connector is a pipe connector which is inserted into the fuel pipeline, and the other end of the quick connector is provided with a fuel pipeline insertion hole for inserting the fuel pipeline, so that the connection of different pipelines is realized through the quick connector. In specific application, one end of the pipe joint is always provided with an annular bulge which is in interference connection with the fuel pipeline so as to clamp the pipe joint and the fuel pipeline, but after long-time use, the pipe joint and the fuel pipeline are easy to loosen, so that the pipe joint and the fuel pipeline are not sealed any more, and oil leakage of the pipeline is caused.
Disclosure of Invention
The utility model aims to provide a: aiming at the problem that in the prior art, the pipe joint nozzle is connected with the fuel pipeline only by adopting an interference bump, so that the connection mode between the pipe joint nozzle and the fuel pipeline is unreliable, the quick connector for the fuel pipeline is provided, and the connection between the pipe joint nozzle and the fuel pipeline is more reliable.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
a quick connector for a fuel pipeline comprises a quick connector body, wherein one end of the quick connector body is provided with a pipe connector which is inserted into an external pipeline, the periphery of the pipe connector is outwards protruded with at least two clamping rings, and a first sealing ring is arranged between any two adjacent clamping rings.
The utility model adopting the technical scheme is provided with at least two clamping rings, and a first sealing ring is sleeved between the adjacent clamping rings, so that the connection tightness between the quick connector body and the connector body is further enhanced; in addition, when being equipped with a plurality of joint rings, the number of first sealing washer also can corresponding increase to further strengthen the reliability of quick connector body and this body coupling of bayonet joint.
Furthermore, an arc-shaped groove is formed in the position, where the pipe joint nozzle is connected with the first sealing ring in a clamping mode, and the size of the groove is matched with that of the first sealing ring. The pipe joint mouth is provided with the groove, so that the first sealing ring can be conveniently clamped, and the first sealing ring is not easy to slide in the axial direction of the pipe joint mouth after being clamped.
Furthermore, after the pipe connector is connected with an external pipeline, the pipe connector and the external pipeline are connected together through heat seal welding. The high-temperature heat seal welding mode is adopted, so that the joint parts of the pipe joint and the external pipeline are fused together, and the sealing performance and the durability of the pipe joint after the pipe joint is connected with the external pipeline are further enhanced.
Furthermore, the bulge of joint ring is barb form, and joint ring barb is towards the other end of quick connector body. The barb-shaped bulge facilitates the insertion of the pipe connector into the external pipeline and simultaneously prevents the pipe connector from being separated from the external pipeline.
Furthermore, the other end of the quick connector body is provided with a pipeline insertion hole, and two second sealing rings are placed in the pipeline insertion hole. The double sealing rings in the pipeline insertion holes are arranged, so that the external pipeline is more tightly matched with the pipeline insertion holes through the two second sealing rings, the connection tightness is enhanced, and fuel oil is prevented from leaking from the position.
Furthermore, the periphery of the other end of the quick connector body is provided with an anti-skidding structure. Be equipped with anti-skidding structure on the quick connector body, make things convenient for being connected of quick connector body both ends and outside pipeline, reduce the quick connector body and produce the rotation when connecting.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the quick connector comprises a quick connector body, a quick connector body and a connector body, wherein at least two clamping rings are arranged, and a first sealing ring is sleeved between the adjacent clamping rings to further enhance the connection tightness between the quick connector body and the connector body; in addition, when being equipped with a plurality of joint rings, the number of first sealing washer also can corresponding increase to further strengthen the reliability of quick connector body and this body coupling of bayonet joint.
