Abstract
The utility model relates to a pipeline joint which comprises a joint body and a nut, wherein, a sealing ring and a cutting sleeve are arranged between a joint body cavity and a pipe to be connected. The inner side of the cutting sleeve is provided with gear teeth engaged with the surface of the pipe to be connected. The utility model is suitable for the connection of plastic pipes or aluminum plastic composite pipes. The pipeline joint has the advantages of simple installation, good sealing effect, certain bond strength, etc.
Description
The utility model relates to a kind of pipe coupling, especially a kind of joint that is used for the connection of plastic tube or aluminium-plastic composite pipe.
The pipe coupling variety type is a lot.The joint that certain intensity and good sealing effect are arranged, is installed inconveniently at the structure more complicated, needs the professional workforce of certain knowledge and experience, uses special tool(s) to install.
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of special tool(s) that do not need just can install, and the pipe coupling of certain intensity, good sealing effect is arranged.
The utility model comprises fittings body and the nut of being with inner chamber.Between by adapter road and fittings body inner chamber, be provided with seal ring, to realize sealing effect.Also be provided with cutting ferrule at the fittings body inner chamber with between being taken in addition, the inboard of this cutting ferrule, promptly be provided with the elasticity teeth towards the direction of being taken over the surface, the true dip direction of elasticity teeth is consistent with the direction of insertion that quilt is taken over, and makes fitting operation very convenient like this.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model;
Fig. 2 is a ssembly drawing of the present utility model.
With reference to Fig. 1, the utility model comprises fittings body (7), nut (3) and seal ring (4), and fittings body (7) is provided with inner chamber (7A), and nut (3) is rotatably connected in the external screw thread (7B) of fittings body by internal screw thread (3A).In addition, the utility model also is provided with cutting ferrule (6), and the inboard of cutting ferrule (6) is provided with elasticity teeth (6A).
The true dip direction of elasticity teeth (6A) is consistent with the direction of insertion of being taken over (1).
In order to make the Elastic Teeth toilet article that one elasticity and intensity be arranged, elasticity teeth (6A) are provided with stiffening rib in one or both sides.
Between cutting ferrule (6) and seal ring (4), can also be provided with packing ring (5).Packing ring (5) is set can be prevented to cause seepage owing to cutting ferrule (6) surface irregularity.
Nut (3) end is provided with a protruding circle (3B), and the size of this protruding circle (3B) is corresponding with seal ring (4).
In addition, in order further to improve bond strength and sealing effect, in by adapter (1), be provided with inner sleeve (2).
During installation, inner sleeve (2) is put into taken over (1) earlier; Being taken over outside (1), be inserted in nut (3); Be inserted in seal ring (4), packing ring (5) and cutting ferrule (6) to taking over outside (1) successively then; To be taken over (1) again and be inserted fittings body inner chamber (7A) together with sealing seal (4), packing ring (5) and cutting ferrule (6); At last nut (3) is tightened in fittings body.In screwing nut (3) process, the protruding circle (3B) in the nut compresses seal ring (4) with packing ring (5), reaches sealing purpose.Because cutting ferrule (6) inboard is provided with elasticity teeth (6A), will be taken over (1) tightly interlock, improved bond strength greatly.
The utility model has the advantage of simple in structure, easy for installation, and good sealing effect, Bond strength is bigger.
