Abstract

The utility model relates to a metallic joint belonging to the technical field of a conduit joint, which comprises a main body, wherein external threads are respectively arranged on both ends of the main body. The metallic joint is characterized in that the external threads are connected with a pressing screw cap in a matching mode through a flexible pipe, and the external threads are screwed with a nut for matching. The metallic joint has simple structure and reasonable design, the joint is inserted into a pipe and is tightly screwed, the external diameter of the pipe is more firmly sleeved through the pressing screw cap, the connection of the metallic joint is labor-saving, the combination is proper, the leak-proof effect is good, simultaneously, materials are saved, and the manufacturing cost is reduced.

Description

Metal joint

Technical field

The utility model belongs to the pipe coupling technical field, is specifically related to metal joint.

Background technique

Known various pipe joint all has plug assembly, be that this pipe joint can be by inserting a pipe that will connect, compress by managing and protecting cover then, outside sheath, also to clamp by clamping ring, fix by nut in the clamping ring outside, the known pipe joint structure of this class is complicated and be made up of considerable part, so this class pipe joint is very heavy and price is high.

The model utility content

At the shortcoming that exists in the prior art, the utility model purpose is to provide the technological scheme of metal joint, makes things convenient for the installation of pipe.

For achieving the above object, the technical solution adopted in the utility model is as follows:

Described metal joint comprises main body, and the main body two ends have outside thread respectively, it is characterized in that outside thread and urgent nut are connected by flexible pipe, outside thread and nut threaded.

Described metal joint is characterized in that the inboard end of described urgent nut is provided with the convex edge.

Described metal joint is characterized in that described urgent nut inboard is smooth.

Above-mentioned metal joint, simple in structure, reasonable in design, joint inserts pipe and screws, and is more firm by the locknut socket in tube outer diameter, and its connection is laborsaving, combination is proper, has good leak preventing effect, saves material simultaneously, has reduced cost of production.

Description of drawings

Fig. 1 is the utility model structural representation.

Embodiment

Now, the utility model is described in further detail by embodiment in conjunction with Figure of description.Metal joint as shown in Figure 1, comprise main body 1, main body 1 two ends have outside thread 4 and outside thread 5 respectively, can change their thread density as required, urgent nut 2 is socketed on the hose outside diameter that will connect, with flexible pipe precession outside thread 4 and screw, again urgent nut 2 is screwed, the inboard smooth and end of urgent nut 2 is provided with the convex edge, combines appropriateness with pipe when screwing, good sealing effect; Outside thread 5 and nut 3 cooperate, and can be fixed on different places to this metal joint, between outside thread 5 and nut 3 seal ring can be set as required, to guarantee the tightness of fixed end.

Claims (3)
