The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Example: See Figure 1-4 A simple pipe joint for filtering impurities in a hydraulic fluid system is shown, comprising a circulating pipe 3 and a cleaning assembly 4, a filter screen 5 is fixedly installed in the inner wall of the circulating pipe 3, the cleaning assembly 4 is matched and installed on the circulating pipe 3, connecting pipes 2 are fixedly installed at both ends of the circulating pipe 3, and connectors 1 are respectively threadedly connected on one side of the two connecting pipes 2 away from the circulating pipe 3;

[0025] The cleaning assembly 4 includes a worm 404 and a moving block 408. A connecting frame 406 is fixedly installed in the middle of the inner wall of the circulation tube 3. A worm gear 405 is rotatably installed at one end of the connecting frame 406 close to the filter screen 5. A cleaning brush 401 is fixedly installed on the side of the worm gear 405 close to the filter screen 5. Connecting shafts 403 are respectively fixedly installed at both ends of the worm 404. The two connecting shafts 403 are rotatably installed in the inner wall of the circulation tube 3. The two connecting shafts 403 respectively penetrate the inner wall of the circulation tube 3 and extend to the outside. A rotating disk 402 is fixedly installed on the side of one connecting shaft 403 away from the worm 404, and a threaded rod 407 is fixedly installed on the side of the other connecting shaft 403 away from the worm 404. The threaded connecting rod 407 has a threaded connection A moving block 408 is connected, and a plug-in block 409 is fixedly installed on the side of the moving block 408 away from the threaded rod 407. A tray is provided at the bottom of the threaded rod 407 to prevent the moving block 408 from falling off the threaded rod 407. A mounting block 4010 is fixedly installed on the side of the outer wall of the turnover tube 3 close to the threaded rod 407. A fixed shaft 4011 is fixedly installed on the bottom of the mounting block 4010, and a torsion spring 4012 is sleeved on the fixed shaft 4011. A limit block 4013 is fixedly installed on one end of the torsion spring 4012, and a fixed shaft 4011 is fixedly installed on the other end of the torsion spring 4012. When the torsion spring 4012 drives the limit block 4013 to reset and contact with the moving block 408, the threaded rod 407 is prevented from rotating under vibration.

[0026] In this embodiment, refer to Figure 1 and Figure 2 As shown, the top of the limit block 4013 is in contact with the moving block 408, the plug-in block 409 is in a "T" shape, and the vertical height of the sliding block 4014 is greater than the vertical height of the plug-in block 409. When the plug-in block 409 moves out of the through hole 6, the sliding block 4014 still slides in the through hole 6 to prevent the plug-in block 409 from rotating as the threaded rod 407 rotates.

[0027] In this embodiment, refer to Figure 1 and Figure 2 As shown, a through hole 6 is opened on one side of the inner wall of the turnover tube 3 close to the plug-in block 409 , and sliding blocks 4014 are fixedly installed on the two symmetrical outer walls of the plug-in block 409 , and the two sliding blocks 4014 are slidably installed in the through hole 6 .

[0028] In this embodiment, refer to Figure 1 and Figure 2 As shown, the horizontal cross section of the through hole 6 is in the shape of a cross, and the outer wall of the protruding portion of the plug-in block 409 is in contact with the inner wall of the through hole 6.

[0029] In this embodiment, refer to Figure 1 and Figure 2 As shown, the cleaning brush 401 contacts the surface of the filter screen 5, and the worm 404 and the worm wheel 405 mesh with each other, so that when the worm 404 rotates, the worm wheel 405 will be driven to rotate, and the connecting frame 406 is "L" shaped, and the folded end of the connecting frame 406 is rotatably mounted with the worm wheel 405.

[0030] Working principle: During use, when a large amount of stains accumulate on the filter 5 in the device, first, turn the limit block 4013 to flip it so that the limit block 4013 does not contact the moving block 408, and then rotate the rotating disk 402 to drive the connecting shaft 403 and the worm 404 to rotate synchronously. When the worm 404 rotates, the worm wheel 405 will rotate driven by the worm 404. When the worm wheel 405 rotates, it will drive the cleaning brush 401 to clean the filter 5. As the connecting shaft 403 rotates, the threaded rod 407 at the bottom will also start to rotate, and drive the moving block 408 and the plug-in block 409 downward to open the through hole 6. As the cleaning brush 401 rotates, the cleaned stains on the filter 5 will fall from the through hole 6 to achieve cleaning.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
