In the pipe joint, the front limit flange and the stop side wall are communicated with the tubular joint, so that water can infiltrate into the space between the front limit flange and the stop side wall, and solid impurities can be contained in the water, so that the impurities are easily accumulated between the front limit flange and the stop side wall once entering the space between the front limit flange and the stop side wall, the balls can be damaged, the efficiency of the balls is reduced, the accumulated impurities can prevent the smooth rotation of the joint relative to the inner pipe, and the joint can not rotate relative to the inner pipe in serious conditions, so that the joint can not be smoothly screwed on the inner thread sleeve.
Disclosure of Invention
The invention aims to provide a further improved structure of a pipe joint which can prevent impurities in water from entering a containing cavity provided with a ball, ensure that the rotation of the joint is not hindered by a connected flexible water pipe and can be smoothly sealed and screwed in an internal thread sleeve.
The utility model is realized by the following steps that the joint comprises a joint body, an inner pipe and an outer screw thread, wherein one end of the joint body is connected with a tubular joint, the inner pipe is rotatably connected in the joint body in a penetrating way, the outer side wall of the tubular joint is provided with the outer screw thread, a perforation is arranged in the joint body, the diameter of the perforation is smaller than that of the pipe hole of the tubular joint, a locking side wall is formed between the perforation in the joint body and the pipe hole of the tubular joint, the inner pipe comprises a front section connecting section and a rear section connecting section connected with a flexible water pipe, the front section connecting section passes through the perforation, a front limiting structure and a rear limiting structure are respectively arranged outside a front port and a rear port corresponding to the perforation on the front section connecting section, the front limiting structure and the locking side wall are respectively provided with a plurality of balls, the front limiting structure is a circular ring-shaped flange, the diameter of the circular flange is slightly smaller than that of the pipe hole of the tubular joint, and an inner sealing ring is arranged between the circular flange and the inner wall of the pipe hole of the corresponding tubular joint.
Here, the stopper side wall of the tubular joint is provided with a circular groove so that the ball can roll only in the circular groove.
The outer surface of the circular flange is provided with an outer circular groove, the inner sealing ring is arranged on the outer circular groove, or the inner wall of the pipe hole corresponding to the circular flange is provided with an inner circular groove, and the inner sealing ring is arranged on the inner circular groove.
The rear limiting structure is a clamp spring, a clamp spring groove is formed in the front section connecting section and corresponds to the rear end opening of the through hole, and the clamp spring is arranged on the clamp spring groove.
And a flange is arranged on the other end surface of the connector body corresponding to the clamp spring. The flange is adopted, so that the contact surface between the clamp spring and the flange is small, and the clamp spring can rotate relative to the joint body more smoothly.
When the joint body is rotated, the inner pipe fixedly connected with the soft water pipe cannot rotate along with the rotation of the joint body under the obstruction of the soft water pipe, so that the joint body smoothly rotates along the axis to drive the tubular joint to be screwed into the sleeve-shaped interface with the internal thread until the tubular joint is in place and is pressed on the sealing ring in the sleeve-shaped interface, and the end part of the tubular joint is tightly abutted against the sealing ring preset in the sleeve-shaped interface to form sealing connection. The annular groove is formed in the stopping side wall, and the plurality of balls are arranged between the annular groove and the stopping side wall, so that when the sleeve-shaped interface end portion of the water gun is pressed on the front limiting flange, the plurality of balls are arranged between the annular groove and the stopping side wall, and the rolling friction force of the balls is very small, so that even if the sleeve-shaped interface end portion of the water gun is tightly pressed on the front limiting flange, the smooth rotation of the joint body relative to the inner pipe cannot be influenced.
Since the inner pipe is not rotated by the rotation of the coupling body, the coupling operation of the male screw coupling is not hindered by the flexible water pipe to which the inner pipe is coupled during the screwing process, and thus the flexible water pipe does not substantially affect the coupling operation. After the connection is completed, the inner pipe and the joint body are connected in a sealing mode through the sealing ring arranged in the through hole, so that the inner pipe and the joint body can rotate relatively, and therefore in the using process, the water gun can not be hindered by the water hose no matter what posture the water gun is used, and therefore the water gun is convenient to use.
The inner sealing ring is arranged between the circular ring-shaped flange and the inner wall of the pipe hole of the corresponding tubular joint, so that water is not easy to seep into the circular ring-shaped flange and the stop side wall, and therefore impurities in the water cannot enter along with the water, the phenomenon that the smooth rotation of the joint relative to the inner pipe is blocked due to the entering of the impurities in the prior art, and the phenomenon that the joint cannot rotate relative to the inner pipe is caused in serious cases is avoided.
Compared with the prior art, the utility model, have and prevent that aquatic impurity from getting into the appearance intracavity that is provided with the ball, guarantee to connect the rotation not receive the soft water pipe that connects the hindrance, can smoothly seal the advantage of cup jointing in the internal thread cover soon.
