Centering mechanism for hot melting of socket insertion type plastic pipe and pipe connecting 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 ...

[0007] Below in conjunction with accompanying drawing, the present invention will be further described:

[0008] See attached figure 1 1. One end of the screw rod 1 is flexibly and fixedly connected with the umbrella head 12 which is evenly distributed with three umbrella bone grooves 11. The umbrella head 12 is flexibly connected with the umbrella rib 7 through the connecting pin 9. The screw sleeve 2 of the groove 14 is connected, and one end of the three rib supports 8 is fixed in the corresponding rib groove 10 by connecting pins 9 respectively, and the other ends of the three rib supports 8 are respectively fixed on the screw sleeve 2 by pins 3. In some umbrella rib installation grooves 14, centering claws 6 are respectively fixed in the centering claw grooves 13 at the tops of three umbrella ribs 7 by pins 4. The rear ends of the centering claws 6 are fixed with rubber pads 5. The end of the screw 1 is provided with a square head, and the screw 1 adopts a left-hand thre...
