[0031] Furthermore, the number of the branch pipes 101 a is four, and the anti-drop protection members 101 b are installed at the top and bottom of the branch pipes 101 a.

[0032] Furthermore, the surface of the fixing block 101b-1 is fixedly connected to the connection point of the branch pipe 101a, and an arc-shaped groove 101b-1a is formed through the surface of the fixing block 101b-1.

[0033] Furthermore, the arc groove 101b-1a is adapted to the movable block 101b-2, and the movable block 101b-2 is movably installed inside the arc groove 101b-1a. The surface of the anti-sliding block 101b-3 is provided with a groove 101b-3a used in conjunction with the movable block 101b-2.

[0034] Furthermore, one end of the vertical rod 101b-3b away from the anti-sliding block 101b-3 passes through the interior of the fixed block 101b-1 and is in sliding contact with the fixed block 101b-1. The vertical rod 101b-3b is located on the inner side of the spring 101b-3c.

[0035] Furthermore, one end of the spring 101b-3c is fixedly connected to the surface of the fixed block 101b-1, and the other end of the spring 101b-3c is fixedly connected to the surface of the anti-sliding block 101b-3.

[0036] Furthermore, the mounting groove 101d is adapted to the sealing plate 102a, and the mounting groove 101d and the first screw hole 101e are in a communicating state.

[0037] Furthermore, a slot 102a-1 for use with the cover plate 102b is defined at the bottom of the sealing plate 102a, and a second screw hole 102a-2 is defined at the bottom of the sealing plate 102a and through the inner cavity of the slot 102a-1.

[0038] Furthermore, a third screw hole 102b-1 is formed through the surface of the cover plate 102b, and the first screw hole 101e, the second screw hole 102a-2 and the third screw hole 102b-1 are all adapted to the anti-loosening bolt 102c.

[0039] Furthermore, the outer side of the arc filter 102a-3 is in sliding contact with the inner wall of the transmission groove 101c, and the connection between the sealing plate 102a and the installation groove 101d and the connection between the covering plate 102b and the card groove 102a-1 are both sealed.

[0040] It should be noted that the inner ends of the multiple arc-shaped filter screens 102a-3 are in a connected state. By setting the fixed block 101b-1 and the arc groove 101b-1a, the rotation space requirement of the movable block 101b-2 can be met, and the installation requirement of the spring 101b-3c can also be met. By setting the movable block 101b-2 and the groove 101b-3a, the movable block 101b-2 can be pressed and contacted with the groove 101b-3a when rotating, so as to drive the anti-sliding block 101b-3 to produce displacement. By setting the vertical rod 101b-3b, the anti-sliding block 101b-3 can be positioned and guided to ensure the displacement stability of the anti-sliding block 101b-3 and avoid the bending of the spring 101b-3c itself. By setting the spring 101b-3c, it can be elastically connected with the anti-sliding block 101b-3 The sealing plate 102a and the mounting groove 101d are provided so that the plurality of arc-shaped filter screens 102a-3 can be placed in the transmission groove 101c in the installed state. The card slot 102a-1 can meet the installation space requirement of the cover plate 102b. The second screw hole 102a-2, the first screw hole 101e and the third screw hole 102b-1 can be threadedly connected with the anti-loosening bolt 102c, and the cover plate 102b can be fixedly installed in the card slot 102a-1 and the sealing plate 102a can be fixedly installed in the mounting groove 101d in turn. The arc-shaped filter screen 102a-3 can increase the filtering area by utilizing its own arc-shaped design, which is conducive to good filtering treatment of the medium.

[0041] In actual application, the side of the anti-slip block 101b-3 away from the vertical rod 101b-3b is an anti-slip rubber block. When clamping the peripheral pipeline, the anti-slip rubber block produces elastic deformation to increase the positioning friction and improve the anti-slip protection effect.

[0042] When in use, all components are in the initial state. First, the branch pipe 101a is connected to other pipelines in the hydraulic system, and the movable block 101b-2 is driven to rotate in the arc groove 101b-1a until the movable block 101b-2 is in a vertical state. With the cooperation of the groove 101b-3a, the anti-sliding block 101b-3 is driven to displace and make anti-slip contact with the external pipeline. The spring 101b-3c is in a stretched state, completing the anti-slip positioning of the pipeline. Then, the sealing plate 102a is moved up and placed in the installation groove 101d, so that the arc filter 102a-3 enters the transmission groove 101c, and then the covering plate 102b is moved up and enters the card slot 102 a-1, and rotate the anti-loosening bolt 102c to pass through the third screw hole 102b-1, the second screw hole 102a-2 and the first screw hole 101e in sequence, so that the covering plate 102b and the sealing plate 102a can be stably installed. In this state, when there are impurities in the hydraulic system pipeline and enter the transmission seat 101, they will be intercepted by the arc filter 102a-3, and the clean medium will flow out from other branches 101a. After long-term use, impurities in the transmission seat 101 gradually accumulate. When it is necessary to clean the impurities, unscrew the anti-loosening bolt 102c and detach the covering plate 102b and the sealing plate 102a in sequence to clean and discharge the impurities.

[0043] In summary, by setting the installation groove 101d, the first screw hole 101e and the filter element 102, the medium flowing through can be intercepted and filtered when the arc filter 102a-3 is installed, ensuring the cleanliness of the medium entering other branches 101a, and the sealing plate 102a and the covering plate 102b can be flexibly disassembled and assembled, which is convenient for the centralized discharge and cleaning of impurities in the transmission groove 101c, which is more in line with actual usage needs.
