As a further description of the above technical solution:

the bottom of the sleeve is bent inwards to form a conical sleeve, the conical sleeve and the guide sleeve are coaxially distributed, and the small end of the conical sleeve is located at the bottom of the sleeve.

As a further description of the above technical solution:

and the small end of the guide sleeve is provided with an arc-shaped annular folded edge facing outwards.

As a further description of the above technical solution:

the bottom of the guide sleeve extends out of the conical sleeve, and a flange is fixedly arranged on the outer surface wall.

As a further description of the above technical solution.

And the top surface wall of the annular plate is provided with an annular groove.

As a further description of the above technical solution:

the section of the annular groove is V-shaped.

As a further description of the above technical solution:

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses in, the annular plate of annular form is inwards bent at sheathed tube top, and the casing pipe cover is established when the copper insert tip, and when moulding plastics with the plastic tubing heat and connecting, the annular plate plays increase area of contact's effect, and the guide tube that the annular plate hole was bent to the casing pipe inserts the copper insert hole, and the outlying and the hole periphery of annular plate are the fillet transition, and are more pleasing to the eye, and is consequently more stable with the plastic tubing nestification.

2. The utility model discloses in, sheathed tube bottom is equipped with a conical sleeve, and conical sleeve and uide bushing are coaxial and have the clearance, and the tip of conical sleeve outwards is provided with an annular hem, and the uide bushing stretches out annular hem downwards simultaneously, and from this, when uide bushing bottom one end inserts the copper inserts, under the direction of its bottom flange and conical sleeve bottom annular hem, cooperation simple to operate has the clamp force simultaneously, and is fixed firm.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a PPR pipeline copper insert trades cover, includes sleeve pipe 1, and the top of sleeve pipe 1 is inwards bent to have and is vertical distribution's annular slab 2 with sleeve pipe 1, and the inside wall of annular slab 2 is bent to have and is located sleeve pipe 1's uide bushing 3, and uide bushing 3 distributes with the axle center with sleeve pipe 1, utilizes 3 buckles of uide bushing in the interior area of contact of 2 increases of annular slab and plastic pipe of copper insert, improves the stability of hot plastic bonding.

Specifically, as shown in fig. 1, the bottom of the sleeve 1 is bent inwards to form a conical sleeve 4, the conical sleeve 4 and the guide sleeve 3 are coaxially distributed, the small end of the conical sleeve 4 is located at the bottom of the sleeve 1, the small end of the conical sleeve 4 is located at the lower portion and is close to the portion clamped by the copper insert, and the phenomenon that the conical sleeve falls off after installation cannot occur.

Specifically, as shown in fig. 1, the small end of the guide sleeve 3 is provided with an arc-shaped annular folded edge 5 facing outward, and the annular folded edge 5 has a guiding function at the outward folded position.

Specifically, as shown in fig. 1, the bottom of the guide sleeve 3 extends out of the conical sleeve 4, a flange 6 is fixedly arranged on the outer surface wall, the flange 6 is matched with the external annular folded edge 5 to clamp and fix the copper insert in a bidirectional manner, meanwhile, the contact area between the copper insert and the flange is reduced, and the combination of the copper insert and the flange is convenient.
