a double-socket pipe fitting comprises a double-socket pipe fitting body and two sealing rings, wherein the double-socket pipe fitting body is in a circular pipe shape, and two ends of the double-socket pipe fitting body are bellmouths; the inner wall at two socket pipe fitting body middle parts is equipped with the bellied location step of round, and the inner wall of two socket pipe fitting body both sides all is equipped with the round sealing washer mounting groove, and two sealing washers are installed on the inner wall of two socket pipe fitting bodies through two sealing washer mounting grooves respectively.

Preferably, the inner wall of the sealing ring is of a multi-tooth-shaped structure with the thickness gradually increased in a step-increasing manner. The multi-tooth-shaped structure with the thickness gradually increased is convenient for the insertion of the pipe and can well compress the pipe, thereby ensuring good sealing property.

Preferably, the outer wall of the double socket pipe body is wound with a spiral structural wall. The structural wall can improve the rigidity of the pipe fitting ring, and the adaptability is stronger.

Preferably, the double-socket pipe fitting further comprises a pressing plate and screws, a circle of pressing plate groove is formed in the middle of the inner wall of the sealing ring, a circle of pressing plate is arranged in the pressing plate groove, screw holes are uniformly distributed in the pressing plate, and the screws penetrate through the pressing plate and the sealing ring to press the sealing ring on the inner wall of the pipe fitting.

Preferably, the screw is a self-tapping screw.

Preferably, the contact part of the sealing ring and the double socket pipe fitting body is provided with an R-shaped water-closing ring. The water sealing performance of the pipe fitting and the sealing can be effectively improved.

Compared with the prior art, the utility model discloses technical scheme's beneficial effect is:

the utility model provides a two socket joint pipe fittings, its socket joint position has assembled the sealing washer, only need paint emollient during the construction, can directly be connected with tubular product, and the construction is faster, more convenient than current product.

Detailed Description

The drawings are for illustrative purposes only and are not to be construed as limiting the patent;

for the purpose of better illustrating the embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product;

it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

The technical solution of the present invention will be further explained with reference to the accompanying drawings and examples.

Example 1

As shown in fig. 1, the double socket pipe fitting comprises a double socket pipe fitting body 1 and two sealing rings 2, wherein the double socket pipe fitting body 1 is in a circular pipe shape, and two ends of the double socket pipe fitting body are mouthpieces; the inner wall at the middle part of the double-socket pipe fitting body 1 is provided with a circle of raised positioning steps 5, the inner walls of the two sides of the double-socket pipe fitting body 1 are respectively provided with a circle of sealing ring mounting grooves, and the two sealing rings 2 are respectively mounted on the inner wall of the double-socket pipe fitting body 1 through the two sealing ring mounting grooves.

The inner wall of the sealing ring 2 is of a multi-tooth structure with the thickness gradually increased in a step-by-step mode. The multi-tooth structure with the thickness gradually increased is convenient for the insertion of the pipe 7 and can well compress the pipe 7, thereby ensuring good sealing property.
