Background technique
Pipeline is widely used in industry, agricultural and urban construction at present, as is applied in aspects such as water supply, coal gas.Pipeline needs pipe joint to connect in installation process, so pipe joint is most important to the reliability and the sealing of pipeline.In recent years, the plastic tube in the novel tube that is widely used (as: plastic-aluminum pipe, PEX pipe etc.) and the Placement of metal pipe (thin-wall copper pipe, thin-wall stainless steel etc.) had various ways.In order to save pipeline, the casting copper sleeve and the plastic pipe joint of extensive use in the market are first-class, all have different defectives, install, dismantle loaded down with trivial details, effort, or sealing is not good enough, connects insecure, and usually be the undergauge butt joint, can influence the flowing velocity of gas, liquid like this; In addition, because cost is higher, bring economic burden to the user.Therefore, existing pipe joint is subjected to the restriction of raw material and making method, thereby has influenced the quality of connection of whole pipeline.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, be convenient to operate, good airproof performance and can realize the card convex type joint of the connection thin metallic tubd of isometrical butt joint.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the card convex type joint that connects thin metallic tubd, comprise pipe joint body and locking nut, it is characterized in that: be shaped on outside thread and six side's boss on the described pipe joint body outer wall, pipe joint body outer wall is shaped on one domatic section near the front end place, is shaped on groove on domatic section outer wall; Described locking nut internal diameter is shaped on the internal thread that matches with the pipe outside thread of pipe joint body outer wall, also is shaped on six side's boss on the outer wall of locking nut, is provided with seal ring in the groove on domatic section outer wall of described pipe joint body.
The utility model can also adopt following technological scheme:
The outside thread that is shaped on the described pipe joint body outer wall is the standard pipe outside thread.
It is the standard pipe internal thread that described locking nut internal diameter is shaped on the internal thread that matches with the pipe outside thread of pipe joint body outer wall.
Described card convex type joint is a straight-through structure.
Described card convex type joint is the bending head type structure.
Described card convex type joint is the Three way type structure.
Advantage and the good effect that the utlity model has are: the utility model adopts technique scheme, the pipe joint body is shaped on domatic section near the front end place, be convenient to connect after the pipe reaming of rising and be with bell-mouthed thin metallic tubd, thereby the problem of having avoided the metal tube internal diameter to dwindle has realized that joint is connected with the isometrical of thin metallic tubd; This card convex type joint convenience quick for installation, good airproof performance, cost optimization can be widely used in industry and domestic water supply or the gas pipe fitter journey.
