Centering mechanism for hot-melting of socket-type plastic pipe and sleeve

Abstract

The invention relates to a centering mechanism for hot melting of a socket insertion type plastic pipe and a pipe connecting sleeve. The centering mechanism is characterized in that the end of a screw rod is movably fixed and connected with an umbrella head provided with uniformly distributed umbrella rib head grooves, the umbrella head is movably connected with umbrella ribs through connecting pins, the screw rod is connected with a screw sleeve provided with uniformly distributed umbrella rib installing grooves through screw threads, one support ends of the umbrella ribs are movably fixed in the corresponding umbrella rib grooves through connecting pins, the other support ends of the umbrella ribs are respectively and movably fixed in the umbrella rib installing grooves arranged on the screw sleeve through pins, and through the pins, a centering claw is movably fixed in a groove of a centering claw groove arranged at the top ends of the umbrella ribs. Compared with the prior art, the centering mechanism has the advantages that the effect of maintaining the consistency between the axis of the pipe connecting pipe and the socket insertion type plastic pipe can be effectively reached, so the defects that the connecting intensity of the electric heating melting belt is nonuniform, and the pipe can easily deform and crack can be overcome. The socket insertion type plastic pipe formed by the socket insertion pipe plastic pipe and the pipe connecting sleeve through hot melting is applicable to the construction in various environments, and the engineering schedule is improved.

Description

[0001] The invention relates to a centering mechanism for hot-melting socket-type plastic pipes and connecting sleeves, which relates to the technical field of plastic pipe socket-connecting fittings, and is used for connecting socket-type plastic pipes and connecting sleeves. Background technique [0002] In existing drainage projects, underground drainage pipes are buried, and plastic pipes are used as buried pipes. The connection methods: electric melting belt connection, clamp connection, heat shrink connection, flange connection, etc., are generally connected manually , Some connection methods have better strength, but the connection is difficult and the process is complicated. There are also connection methods that are not suitable for water-carrying operations, especially the human factor of heating with a flame gun is very large. When hot-melting, because no centering mechanism is used, the connection strength between the socket-type plastic pipe and the socket sleeve ...

Problems solved by technology

[0004] The obvious advantages and effects after the implementation of this technology are: when the socket-type plastic pipe is connected, the axial center of the socket-type plastic pipe and the sleeve of the socket can be effectively kept consistent, thus overcoming the uneven connection strength of the electric heating belt and the easy deformation of the pipe and cracking defects
