Utilize the copper insert conversion adapter of this model utility, injection-moulded plastic in the plastically welding section A at the two ends of copper insert conversion adapter and the through hole of plastically welding section C, plastics infiltrate joint from through-hole groove and finally make plastics and copper insert conversion adapter tightly merge, thus improve degree of adhesion and the sealing of plastics and copper insert conversion adapter.
Preferably, the outer surface of described exposed metal/bare metal section B offers groove N.
Preferably, the internal surface of described exposed metal/bare metal section B offers groove O.
Preferably, described groove O is that dove-tail form hooks groove.
In the utility model, offer groove N effect at the outer surface of plastically welding section A, plastically welding section C and be similar to screw thread, it is more tight that object is plastics are combined with copper insert crossover sub, and it is also tightr to strengthen sealing in order to what allow the plastics at copper insert crossover sub two ends be combined with copper insert crossover sub for offering some grooves at the internal surface of B section simultaneously and this groove design being become dove-tail form hook groove.
Preferably, preferably, the slotting position of groove N and the slotting position of groove O corresponding relative to copper insert wall.In the utility model, offering groove in the position that the inside and outside surface of the B section of copper insert is corresponding is in order to the plastics of copper insert crossover sub and infiltration can be allowed more to fit, improve tensile strength and the twisting strength of whole joint, also make sealing be improved.
Preferably, the number of groove N and groove O is respectively 2.
Preferably, the number of groove M plastically welding section A and plastically welding section C offered is 2.
Preferably, the number of the through hole in groove M is 4, and the angle of the geometrical center of every two through holes and the line at the several center of groove M is 90 °.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
In the utility model, at the plastically welding section A of copper insert crossover sub, the each injection-moulded plastic in plastically welding section C two ends, plastics are from plastically welding section A, the through-hole groove of plastically welding section C upper groove M infiltrates in joint and finally makes plastics and copper insert tightly merge, thus improve degree of adhesion and sealing, at the plastically welding section A of copper insert, the effect that the outer surface of plastically welding section C arranges some grooves is similar to screw thread, what the plastics at crossover sub two ends were combined with copper insert conversion adapter is tightr, in the exposed metal/bare metal section B of copper insert conversion adapter, groove energy is offered in the position that outer surface is corresponding, all in order to the plastics of copper insert conversion adapter and infiltration can be allowed more to fit, improve tensile strength and the twisting strength of whole joint, also sealing is made to be improved.
