Summary of the invention
The built-in Quick connection part that the utility model provides a kind of simple in structure, quick and easy for installation, good sealing effect, increases work efficiency for solving the technical problem existing in known technology.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is:
A kind of built-in Quick connection part, comprise connecting head, seal ring and outer connecting pipe, it is characterized in that: described connecting head comprises clamping part, be positioned at the integrated joint in clamping part two ends, the inside of described joint is cavernous structure, between two joints, by center hole, be connected, the internal diameter of described center hole is less than the diameter of joint endoporus, and joint endoporus and center hole joint form the spacing shoulder of the first sealing; The excircle of described joint is provided with outside thread, is fitted with locknut on it; Described outer connecting pipe comprises outer connecting pipe main body and connection end, and the external diameter of described connection end is greater than the external diameter of outer connecting pipe main body, and the joint of outer connecting pipe main body and connection end forms the spacing shoulder of the second sealing; The connection end of above-mentioned outer connecting pipe is inserted in the endoporus of above-mentioned joint; Between described connection end and the spacing shoulder of the first sealing, seal ring is installed; Above-mentioned locknut comprises locknut body, the exterior edge face of described locknut body is one-body molded gland, the central position of described gland is provided with the mounting hole coaxial with above-mentioned center hole, the outer connecting pipe main body of described outer connecting pipe is inserted in mounting hole, and the internal diameter of mounting hole and the external diameter of outer connecting pipe main body match; The interior edge face of described gland fits tightly on the spacing shoulder of the second sealing.
The utility model can also adopt following technical measures:
The internal diameter of the center hole of the connection end of described outer connecting pipe and seal and connection two ends joint equals the internal diameter of outer connecting pipe main body.
The outer surface of described gland is integrally formed with protection boss.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, save existing outer connecting pipe welding step, adopt built-in assembly structure, improved traditional manufacturing process, adopt non-welding structure, reduce manufacturing process, greatly improved manufacturing efficiency, and improved the up-to-standard rate of product and the total quality of product; Aspect installation and maintenance, reduce difficulty, reducing operator's labor intensity.
