As a modification, the outer side wall of the hoop is provided with a connecting thread, and the hoop is connected with the internal thread of the compression nut through the connecting thread.

And then, an inner step is formed on the inner side wall of the compression nut, an internal thread of the compression nut is arranged on the side wall of the inner step, a compression head is formed at the lower end of the hoop, a compression inclined plane is formed on the outer side wall of the compression head, and the inner step of the compression nut is abutted to the compression head of the hoop.

And the outer side wall of the lower end of the hoop is uniformly provided with a plurality of open grooves with downward openings.

Compared with the prior art, the utility model has the advantages of: when the coupling connects, at first, with gland nut, the ferrule, compress tightly on cover and the seal cover embolias the connecting pipe in proper order, again with the connecting pipe, the seal cover inserts in the mounting groove of joint main part with compressing tightly the cover, then, also insert the ferrule lower extreme along compressing tightly the lateral wall of cover, rotatory gland nut, connect gland nut in connecting in the joint main part, gland nut drives the ferrule down, under the inclined plane effect between ferrule and joint main part, compress tightly the cover and cramp the seal cover on the outer wall of connecting pipe gradually, the fixed connection of connecting pipe has not only been realized, and simultaneously, still have sealed effect to the connecting pipe.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 3, the novel speed regulation pipe joint for a cylinder in the present embodiment includes a joint main body 1, a compression nut 2, a sealing sleeve 3, a compression sleeve 4, and a ferrule 5.

Wherein, seted up annular mounting groove 11 on the terminal surface that connects main part 1, set up the communicating step with mounting groove 11 on the end lateral wall that connects main part 1, be formed with the inclined plane on the inside wall of step, be provided with in mounting groove 11 and have seal cover 3 and compress tightly cover 4, seal cover 3 has elasticity, compress tightly and seted up the bar hole along length direction on the cover 4, it is outside to compress tightly cover 3 to overlap to compress tightly cover 4, be formed with the external screw thread on the end lateral wall that connects main part 1, the external screw thread top spin has gland nut 2, be provided with ferrule 5 between gland nut 2 and compress tightly cover 4, the lower extreme of ferrule 5 is formed with the inclined plane 51 that compresses tightly with step inclined plane looks adaptation.

In the embodiment of the present invention, the connection between the ferrule 5 and the gland nut 2 has a plurality of structures, and in the first kind, as shown in fig. 1, the outer side wall of the ferrule 5 is formed with a connection thread, and the ferrule 5 is connected with the internal thread of the gland nut 2 through the connection thread.
