Abstract

A hoop device for connecting plastic pipes. The lower end of the plastic pipe upper connecting pipe and the upper end of the plastic pipe lower connecting pipe share a rubber sealing ring in a groove, the rubber sealing ring is simultaneously pressed in arc grooves at the lower end of the plastic pipe upper connecting pipe and the upper end of the plastic pipe lower connecting pipe through a hoop, the inner side of the rubber sealing ring is provided with a structure in which a double-semi-convex arc and the rubber sealing ring are connected, and arc grooves matched with the distance between the double-semi-convex arcs of the rubber sealing ring are respectively arranged at the lower end of the plastic pipe upper connecting pipe and the upper end of the plastic pipe lower connecting. Compared with the prior art, the plastic pipe connecting device overcomes the defects in connection, can effectively prevent the water pipe from sliding, and the rubber fixing ring can ensure the sealing of the connection part, thereby effectively ensuring the connection quality of the plastic pipe, reducing the connection cost and realizing the firm connection between the plastic pipes.

Description

Hoop device for connecting plastic pipes

Technical Field

The utility model relates to a staple bolt device is used in plastic tubing connection relates to that the plastic tubing is connected technical field, is applied to the plastic tubing and connects.

Background

At present, when plastic pipes with larger calibers are connected, the pressure of a unit area is large, the plastic pipes are bonded by glue, the plastic pipes are easy to degum in the long-term use process to cause water leakage, the two plastic pipes are connected by clamping rubber sealing rings through two fixing rings, the connecting device not only increases the connecting difficulty, but also increases the cost, and meanwhile, the dislocation or looseness caused by the long-time water flow vibration causes the water leakage of the joint, and the unnecessary loss is easily caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned defect, improve prior art, design a new connecting device, adopt the arc seal circle of double-barrelled sharing in the staple bolt, realize the connection and the sealing of plastic tubing, a staple bolt device is used in plastic tubing connection of quality when effectively guaranteeing the plastic tubing connection.

The technology is realized as follows: take over, rubber seal, plastic tubing under taking over, the semi-convex circular arc on staple bolt, plastic tubing, its characterized in that: the lower end of the plastic pipe upper connecting pipe and the groove at the upper end of the plastic pipe lower connecting pipe share a rubber sealing ring, the rubber sealing ring is simultaneously pressed in the arc grooves at the lower end of the plastic pipe upper connecting pipe and the upper end of the plastic pipe lower connecting pipe through a hoop,

the inner side of the rubber sealing ring is provided with a structure which is in a shape of a double-semi-convex circular arc and is connected with the rubber sealing ring,

the lower end of the plastic pipe upper connecting pipe and the upper end of the plastic pipe lower connecting pipe are respectively provided with an arc-shaped groove which is matched with the distance between the double semi-convex arcs of the rubber sealing ring when the two pipes are connected.

The obvious advantages and effects after the technology is implemented are as follows: compared with the prior art, the plastic pipe connecting device overcomes the defects in connection, can effectively prevent the water pipe from sliding, and the rubber fixing ring can ensure the sealing of the connection part, thereby effectively ensuring the connection quality of the plastic pipe, reducing the connection cost and realizing the firm connection between the plastic pipes.

Drawings

FIG. 1 is a schematic view of the front view structure of the present invention,

wherein, the device comprises a hoop 1, a plastic pipe upper connecting pipe 2, a rubber sealing ring 3, a plastic pipe lower connecting pipe 4 and a semi-convex circular arc 5.

Detailed Description

The invention will be further described with reference to the accompanying drawings:

referring to the attached figure 1, the lower end of the plastic pipe upper connecting pipe 2 and the groove at the upper end of the plastic pipe lower connecting pipe 4 share a rubber sealing ring 3, the rubber sealing ring 3 simultaneously compresses the rubber sealing ring 3 in the arc grooves at the lower end of the plastic pipe upper connecting pipe 2 and the upper end of the plastic pipe lower connecting pipe 4 through a hoop 1,

the inner side of the rubber sealing ring 3 is provided with a structure in the shape of a double-semi-convex arc 5 connected with the rubber sealing ring 3,

the lower end of the plastic pipe upper connecting pipe 2 and the upper end of the plastic pipe lower connecting pipe 4 are respectively provided with an arc groove which is matched with the distance between the double semi-convex arcs 5 of the rubber sealing ring 3 when the two pipes are connected.

Referring to the attached drawing 1, when two pipes are connected, firstly, according to the distance between the semi-convex circular arcs 5 of the standard rubber sealing ring 3, arc-shaped grooves are respectively processed at the lower end of the plastic pipe upper connecting pipe 2 and the periphery of the upper end of the plastic pipe lower connecting pipe 4, the semi-convex circular arcs 5 at the upper side of the rubber sealing ring 3 are clamped into the arc-shaped grooves of the plastic pipe upper connecting pipe 2, then the semi-convex circular arcs 5 at the lower side of the rubber sealing ring 3 are clamped into the arc-shaped grooves of the plastic pipe lower connecting pipe 4, and bolts are inserted into holes of two semi-circular anchor ears 1 at the outer side of the rubber sealing ring 3 to compress the rubber sealing ring 3, so that the lower end.
