[0002] A pipeline joint is a component used to connect two pipelines or a pipeline and other equipment to ensure that fluid can be smoothly transmitted from one place to another. The design and material selection of the pipeline joint depend on the specific requirements of the application, including the type of fluid, pressure, temperature, and environmental conditions, etc.;

[0003] Currently, when connecting two pipelines, quick joints are usually used for connection to facilitate improving efficiency and convenience. However, the existing quick joints have the following problems:

[0004] Currently, most quick joints do not have the function of cleaning the interior. After long-term use, impurities are likely to block inside the quick joint, making it inconvenient to clean the impurities, which will affect the normal smoothness of the pipeline and reduce the use effect;

[0005] In view of the above problems, the present utility model document proposes a quick joint convenient for impurity cleaning. Content of the Utility Model

[0006] The utility model provides a quick joint convenient for impurity cleaning, which solves the problems in the prior art that most quick joints do not have the function of cleaning the interior, and after long-term use, impurities are likely to block inside the quick joint, making it inconvenient to clean the impurities, which will affect the normal smoothness of the pipeline and reduce the use effect.

[0007] The utility model provides the following technical solutions:

[0008] A quick joint convenient for impurity cleaning, comprising:

[0009] A joint body, wherein a plurality of movable cavities are formed in the inner wall of the joint body, and a ball is movably arranged inside each movable cavity;

[0010] A fixing ring is fixedly arranged on the outer wall of the joint body, a spring is fixedly arranged on one side of the fixing ring, one end of the spring is fixedly provided with a sliding sleeve corresponding to the plurality of balls, the sliding sleeve is slidably connected to the outer wall of the joint body, and anti-slip lines are arranged on the outer wall of the sliding sleeve;

[0011] A cleaning mechanism is arranged on the joint body for cleaning impurities inside the joint body.

[0012] In a possible design, the cleaning mechanism includes two cleaning holes which are opened on the outer wall of the joint body. Two bases corresponding to and communicating with the cleaning holes are fixedly arranged on the outer wall of the joint body. A cover plate is rotatably connected to one side of each base through a rotating shaft, and an observation window is arranged on one side of the cover plate.

[0013] In a possible design, a sealing gasket which fits with one side of the base is arranged on one side of the cover plate. Two threaded plates are fixedly arranged on one side of the base, and two connecting plates corresponding to and fitting with the threaded plates are fixedly arranged on one side of the cover plate. Each cover plate and the connecting plate are fixedly connected through bolts.

[0014] In a possible design, a connecting pipe is arranged at one end of the joint body. A convex ring which abuts against a plurality of balls is fixedly arranged on the outer wall of one end of the connecting pipe, and a card slot for limiting and clamping the plurality of balls is opened on the outer wall of one end of the connecting pipe.

[0015] In a possible design, a limiting ring for limiting the connecting pipe is fixedly arranged on the inner wall of the joint body. A rubber gasket is arranged on one side of the limiting ring, and a sealing ring which fits tightly with the rubber gasket is arranged at one end of the connecting pipe.

[0016] In a possible design, a filter screen is fixedly installed on the inner wall of the joint body.

[0017] In this application, during use, first, the sliding sleeve is pushed to slide on the outer wall of the joint body. At the same time, the sliding sleeve will squeeze the spring fixed on one side, making the spring in a compressed state. Thus, it is convenient for a plurality of movable cavities on the outer wall of the joint body to be exposed, providing space for later activities. Then, one end of the connecting pipe is aligned with the joint body and inserted. The convex ring on the outer wall of the connecting pipe contacts the balls on the inner wall of the joint body, and the balls roll in their respective movable cavities, so as to guide the connecting pipe to be inserted smoothly. As the connecting pipe is further inserted, the balls reach the card slot and are limited and clamped due to the shape of the card slot, realizing the fixed connection between the connecting pipe and the joint body. At this time, the sliding sleeve is released. Under the elastic force of the spring, the sliding sleeve will slide back to its original position, so that the inner wall of the sliding sleeve covers and seals the movable cavity, which is beneficial to preventing the balls from moving randomly in the movable cavity later, further enhancing the locking firmness between the connecting pipe and the joint body, preventing the connecting pipe from falling off accidentally, and achieving the effect of quick connection, improving convenience. At the same time, the anti-slip lines on the outer wall of the joint body can form friction, increasing the anti-slip property when contacting the sliding sleeve and improving the effect of convenient operation.

[0018] While the connecting pipe is being fixedly connected, the sealing ring at one end of the connecting pipe will closely fit with the rubber pad on one side of the limit ring to form a seal, ensuring that there is no leakage at the connection, improving the sealing performance. The limit ring can limit the insertion depth of the connecting pipe, enhancing the applicability. A filter screen is also fixedly installed inside the joint body. The filter screen can block large particle impurities in the fluid, achieving an interception and filtration effect, and further protecting the smooth operation of the joint and the connecting pipe. When it is necessary to clean the impurities inside the joint, first, through the observation window, the situation inside the joint can be observed to judge the position and quantity of the impurities for convenient direct operation. Then, by rotating the bolt, the cover plate is opened from the base, and the impurities inside the joint body can be directly operated and cleaned through the cleaning hole. After the cleaning is completed, the cover plate is reinstalled on the base and fixed by rotating the bolt. The sealing gasket ensures the sealing performance between the cover plate and the base, thereby achieving the function that the quick connector has the function of cleaning the inside. Even after the quick connector has been used for a long time, it is convenient to clean the impurities that appear inside the quick connector, preventing blockage and avoiding affecting the normal smoothness of the pipeline, improving the use effect.

[0019] In the present utility model, for the quick connector facilitating impurity cleaning, through the cleaning mechanism, the quick connector has the function of cleaning the inside. Even after the quick connector has been used for a long time, it is convenient to clean the impurities that appear inside the quick connector.

[0020] In the present utility model, for the quick connector facilitating impurity cleaning, through the settings of structures such as the spring 3, the sliding sleeve, the ball, and the movable cavity, the inner wall of the sliding sleeve can cover and seal the movable cavity, which is beneficial to preventing the ball from moving arbitrarily in the movable cavity later, further enhancing the locking firmness between the connecting pipe and the joint body, preventing the connecting pipe from accidentally falling off, and achieving the effect of quick connection, improving the convenience.

[0021] In the present utility model, the quick connector has the function of cleaning the inside, which is convenient to clean the impurities that appear inside the quick connector, preventing blockage and avoiding affecting the normal smoothness of the pipeline, improving the use effect.
