The union syndeton that generally adopts has following several at present:
1, screw connection structure is provided with screw thread in equal caliber interface, establish the straight pipe type joint of screw thread in being screwed into, so that the tubing processing cost improves greatly;
2, buckle-type structure is provided with sealing ring in the docking port periphery of tube and tube, and the sealing ring periphery adds symmetrical buckle, and is by tightening screw that left and right sides buckle is fastening, so that work progress is extremely inconvenient, complex procedures;
3, welded construction is welded by the metal tube of equal caliber, meets required metal tube when longer, need usually to adopt field Welding, so that construction operation is extremely inconvenient, and also dangerous, efficient is low, the cost height;
4, nut cooperates the horn mouth structure, establish sealing ring in the plastic nut, be screwed into from threaded tube head, make the horn mouth of nut press to this bell-mouthed tube head horn mouth that adapts, play the fastening effect of sealing with this, but owing to adopt plastic material to make product compressive resistance extreme difference, easily split explosively, influence sealing performance.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, the closed-entry ultrasound examination union that provide a kind of safe and efficient, simple in structure, easy to use, good airproof performance, is connected firmly.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
The utility model comprises nut and tube head, it is characterized in that described nut top is made as the downward taper in big footpath, and conical top is provided with circular hole, and the nut middle and lower part is provided with screw thread; Described tube head top sides is along being provided with some reducings, and the tube head inboard is provided with sealing ring, and the outside is provided with screw thread, the terminal weld metal pipe of tube head; Described nut is tightened and is connected in tube head.
Described nut taper is provided with the top of reducing corresponding to tube head, is squeezed in the reducing top outer.
Its path length of the circular hole of described conical top is slightly larger than the metal tube path length, and metal tube passes the circular hole of conical top.
Inboard, described nut middle and lower part is provided with screw thread, adapts with the tube head screw thread.
Described tube head top sides promptly equidistantly is provided with some square breach on the top sides edge along the some reducings that are provided with, and forms the square tube wall of projection between breach and the breach.
The inboard sealing ring that is provided with of described tube head is located at the metal tube outside of interting in tube head.
Described tube head internal diameter be slightly larger than the metal tube external diameter add sealing ring thickness and.
Described nut and tube head are all made with metal material, and its tube head top is toughness slightly.
With respect to prior art, the beneficial effects of the utility model are:
1, omit other operations, need not aid, effectively reach safe and efficient;
2, simple in structure, easy to use;
3, adopt screw thread extruding reducing and fitted seal circle, effectively improve sealing performance and firm degree.
