Description

Technical Field

[0001] This utility model relates to the field of rotary joint technology, and in particular to a rotary joint with oil passage unblocking function. Background Technology

[0002] Rotary joints are widely used in production and daily life as connecting components. According to their applications, rotary joints can be divided into single-circuit rotary joints and double-circuit rotary joints. The connection method of a double-circuit rotary joint can be selected according to the working conditions, and the inlet of the transmission medium can be freely selected to enter from the side or rear end, depending on the working conditions.

[0003] To prevent impurities in the oil from accumulating and causing blockages, existing rotary joints install filter components inside to filter impurities. However, over time, impurities accumulate on the filter screen itself, requiring constant disassembly and cleaning of the filter components, which is cumbersome and has limited practicality. Therefore, we propose a rotary joint with an oil passage unblocking function. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing a rotary joint with oil passage unblocking function.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rotary joint with oil circuit unblocking function, comprising a rotary joint and an interface end. The interface end has a mounting groove extending through its interior. A sealing gasket is provided on the inner side of the mounting groove. A filter screen plate is movably inserted into the mounting groove. A through groove is provided inside the filter screen plate, and a filter screen is provided inside the through groove. A movable shaft is provided inside the interface end. One end of the movable shaft has an unblocking brush on its surface via a connecting piece. A resistance ball is integrally formed on the outside of the movable shaft. A bushing is rotatably fitted onto the outside of the movable shaft. The bushing is fixedly connected to the inner side of the interface end via a connecting shaft. A limiting component is installed at the other end of the movable shaft. A fitting is fitted onto the outside of the movable shaft, and a spring is fixedly connected to the fitting and the bushing.

[0006] Preferably, when the medium enters the interface end and contacts several sets of resistance balls outside the movable shaft, the movable shaft is in a squeezed sliding state inside the bushing, the movable shaft is in a supported rebound state by the spring, and the movable shaft drives the unblocking brush on one side of the connecting piece to penetrate and unblock the filter screen inside the filter screen plate.

[0007] Preferably, when the filter screen is inserted into the mounting groove, both sides of the filter screen are in a sealed engagement with the sealing gasket inside the mounting groove.

[0008] Preferably, the outer periphery of the interface end is threaded, and the surface of the thread is covered with a threaded washer.

[0009] Preferably, the threaded washer has a helical shape and the threaded washer itself has deformation characteristics. The threaded washer itself is made of corrosion-resistant material and has corrosion-resistant properties.

[0010] This utility model provides a rotary joint with oil passage unblocking function. It has the following beneficial effects:

[0011] 1. This rotary joint has an oil circuit unblocking function. In use, the filter screen is first inserted into the mounting groove and sealed by the sealing gasket inside the mounting groove. The interface end has a movable shaft. When the medium enters the interface end and contacts the connecting plate and multiple sets of resistance balls, the movable shaft slides inside the bushing under the impact of the medium and is squeezed by the sleeve. Under the elastic rebound of the spring, the movable shaft moves to the other side, causing the unblocking brush on one side of the connecting plate to penetrate the internal aperture of the filter screen and clean and discharge the impurities adsorbed on the surface of the filter screen. In this way, the movable shaft can move left and right under the flow of medium, driving the unblocking brush to clean, reducing the frequency of filter screen disassembly and cleaning, thereby improving the practical effect of the rotary joint.

[0012] 2. This rotary joint with oil passage unblocking function has a threaded connection on the outer periphery of the interface end, which can be threaded to connect with an external connecting pipe. The surface of the thread is covered with a threaded washer. The threaded washer itself is made of anti-corrosion material and has corrosion-resistant properties. When the external pipe is connected to the interface end, the threaded washer on the outer periphery of the thread can be squeezed against each other, preventing the medium from penetrating to the connection between the external pipe and the interface end, thus improving the anti-corrosion effect at the connection between the external pipe and the interface end. In addition, the threaded washer itself has deformation characteristics, which can facilitate the subsequent rotation and disassembly of the external pipe, avoiding the difficulty of disassembly due to corrosion of the thread surface, thereby achieving the effect of facilitating the disassembly and use of the external pipe of the interface end.
