The utility model mainly aims to provide a withstand voltage type PVC-U drain pipe connecting tube cover can effectively solve the problem among the background art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a withstand voltage type PVC-U drain pipe connecting tube cover, includes first connector, second connector, corrugated connection pipe, hook thorn face is pasted to magic, the terry face is pasted to magic and the insulation cover, first connector one side is equipped with the second connector, be connected with corrugated connection pipe between first connector and the second connector bottom, first connector and second connector top all are equipped with major diameter mouth screwed joint, major diameter screwed joint top is equipped with minor diameter mouth screwed joint.

Furthermore, the periphery of the corrugated connecting pipe is wrapped with a heat insulation sleeve, a hook and loop fastening surface is glued on the inner side of one end of the heat insulation sleeve, and a loop fastening surface is glued on the outer side of the other end of the heat insulation sleeve.

Furthermore, the tops of the first connector, the second connector and the large-diameter threaded connector are all embedded with a sealing ring through gluing.

Furthermore, the heat-insulating sleeve is made of PVC foaming materials.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the pipe sleeve for PVC-U drainage pipe connection is formed by the first connector, the second connector and the corrugated connecting pipe, personnel can respectively connect two ends of the corrugated connecting pipe with two groups of PVC-U drainage pipes to be connected in a threaded manner by arranging the first connector and the second connector at two ends of the corrugated connecting pipe, and can respectively connect the first connector and the second connector with PVC-U drainage pipes with different calibers by arranging the large-caliber threaded connector and the small-caliber threaded connector on the second connector through the first connector, so that the adaptation range of the casing connection is greatly increased, and the use is flexible and convenient.

2. Through the setting of insulation cover, personnel can keep warm to the sleeve pipe periphery that first connector, second connector and ripple connecting pipe are constituteed and protect, in order to increase the stability that the pipe box used, avoid at low temperature environment, the phenomenon of freezing appears in the pipe box that does not have the protection, whole pipe box uses nimble convenient, applicable in the pipe connection of multiple bore uses, pliability through the ripple connecting pipe, can help personnel to stretch between the pipeline of multiple interval and cup joint the intercommunication, good heat preservation effect has, has higher practicality.
