Description
Technical field
This utility model relates to a kind of pipe joint.
Background technology
Screwed pipe joint is generally made up of joint shell and threaded body, and threaded body is set in joint shell, existing connects
Between head shell and threaded body generally by the clamping of rigidity by body card in the enclosure, this connected mode requirement to precision
Height, assembling inconvenience, it is easily caused body and damages, production cost is high.
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is that offer one is easy to assembly, good airproof performance, production cost are low
Pipe joint.
For achieving the above object, this utility model uses a kind of pipe joint, including joint shell and threaded body, joint shell
One end forms connecting portion, and threaded body one end is plugged in the connecting portion of joint shell, the internal diameter of the connecting portion of described joint shell
Shrinking to inner side, the inwall of connecting portion is formed a circle draw-in groove, on threaded body periphery, corresponding draw-in groove forms a circle groove, in groove
Arranging snap ring, threaded body is stuck in draw-in groove realize with joint shell fixing by snap ring.
This utility model is further arranged to the connecting portion of described joint shell and is internally formed two inner rings that outer imperial palace is little,
Being connected by the conical surface between two inner rings, draw-in groove is arranged on little inner ring.
This utility model is further arranged on described threaded body be formed at the conical surface of corresponding joints shell connecting portion seal
Groove, arranges sealing ring in seal groove.
The beneficial effects of the utility model are to arrange snap ring on threaded body, and snap ring has certain contractility, at screw thread
When body is assigned in joint shell, snap ring can retract in the draw-in groove of joint shell connecting portion under extrusion, once enters
In draw-in groove, snap ring recovers, and snap ring blocks the draw-in groove of joint shell and the groove of threaded body simultaneously, it is ensured that joint shell and threaded body
Interfix, easy for installation, sealing ring is set between joint shell and threaded body simultaneously, it is ensured that sealing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model specific embodiment.
Detailed description of the invention
As it is shown in figure 1, specific embodiment of the utility model is a kind of pipe joint, including joint shell 1 and threaded body 2,
Joint shell 1 one end forms connecting portion 11, and threaded body 2 one end is plugged in the connecting portion 11 of joint shell 1, joint shell 1
Connecting portion 11 is internally formed two inner rings (12,14) that outer imperial palace is little, is connected by the conical surface 13 between two inner rings (12,14),
Forming a circle draw-in groove 15 on the little inner ring 12 of connecting portion 11, on threaded body 2 periphery, corresponding draw-in groove 15 forms a circle groove 21, groove
Arranging snap ring 22 in 21, threaded body 2 realizes with joint shell 1 in being stuck in draw-in groove 15 by snap ring 22 fixing, right on threaded body 2
Answer formation seal groove 23 at the conical surface of joint shell 1 connecting portion 11, sealing ring 24 is set in seal groove 23.
