Connecting structure of electromagnetic hot melting pipe fitting

Abstract

The invention discloses a connecting structure of an electromagnetic hot melting pipe fitting. The connecting structure comprises a pipe fitting body, wherein a hot melting inner sleeve is embedded onthe inner wall of a socket of the pipe fitting body, a plurality of electromagnetic induction heat production supporting rings are inlaid in the hot melting inner sleeve in the axial direction at intervals, and the electromagnetic induction heat production supporting rings are coaxially arranged with the hot melting inner sleeve. According to the connecting structure, the hot melting inner sleeveis embedded on the inner wall of the socket of the pipe fitting body, and the plurality of electromagnetic induction heat production supporting rings are inlaid in the hot melting inner sleeve in theaxial direction at intervals, so that heat can be generated by the electromagnetic induction heat production supporting rings through an electromagnetic welding clamp so as to perform hot melting connection on the hot melting inner sleeve and a pipe needing to be connected, the structure is simple, and the operation is convenient; meanwhile, due to the fact that only the plurality of electromagnetic induction heat production supporting rings are adopted to perform hot melting on the hot melting inner sleeve and the pipe, the overall weight of the pipe fitting connecting structure is light, and the cost is low; and moreover, the electromagnetic induction heat production supporting rings can not only play the heat production role, but also can play the supporting role, and the connecting structure is applicable to the connection of pipe fittings.

Description

technical field [0001] The invention relates to the field of plastic pipe fittings, in particular to a connection structure of electromagnetic hot-melt pipe fittings. Background technique [0002] At present, the plastic pipe industry requires simplicity of construction. Traditional time-consuming and labor-intensive hot-melt sockets have been gradually eliminated. Electromagnetic hot-melt connection has become the mainstream process for welding pipe fittings on construction sites. Electromagnetic hot-melt can realize pipe installation and then welding. Multiple connection points can be connected at the same time, and maintenance is very convenient. However, at present, electromagnetic hot melting is only used for steel-plastic pipes, and cannot be used for ordinary plastic pipes. Contents of the invention [0003] The object of the present invention is to provide a connection structure of electromagnetic hot-melt pipe fittings in order to overcome the above-mentioned defi...
