DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Example 1, referring to Figures 1 - 3As shown in the figure, this embodiment discloses a marine air duct filter, which includes a housing 1. A filter element 2 is inserted into the inner wall of the housing 1. A pull ring 3 is fixedly connected to one side of the filter element 2. Connecting pipes 4 are fixedly connected to both sides of the housing 1. The inner walls of the two connecting pipes 4 are communicated with the inner wall of the housing 1. An auxiliary device 5 is arranged on the outer surfaces of the two connecting pipes 4. The auxiliary device 5 includes two auxiliary blocks 51. One sides of the two auxiliary blocks 51 are respectively fixedly connected to both sides of the housing 1. Side plates 52 are fixedly connected to both sides of the auxiliary block 51. A threaded rod 53 is threadedly connected to the inner wall of the side plate 52. One end of the threaded rod 53 is rotatably connected to a clamping plate 54. The clamping plate 54 is arc-shaped. A positioning device 6 is arranged between the housing 1 and the filter element 2. By arranging two clamping plates 54 on the outer surface of the connecting pipe 4, under the action of the threaded rod 53, when the threaded rod 53 is rotated, the threaded rod 53 will expand and contract on the inner wall of the side plate 52. During the expansion and contraction process of the threaded rod 53, it will drive the clamping plate 54 to move synchronously until the two clamping plates 54 completely clamp the connection between the connecting pipe 4 and the air duct system pipe, then it can assist in fixing between the connecting pipe 4 and the pipe of the air duct system, which is beneficial to preventing gaps from appearing at the connection between the two and ensuring the normal operation of the air duct system.

[0029] Refer to Figure 2 and Figure 3 As shown in the figure, a chute 55 is opened at the bottom of the clamping plate 54. Slide bars 56 are symmetrically and fixedly connected to both sides of the housing 1. Both ends of the slide bar 56 are respectively fixedly connected to the outer surface of the connecting pipe 4 and one side of the side plate 52. The outer surface of the slide bar 56 is slidably connected to the inner wall of the chute 55. By arranging the slide bar 56 and the chute 55, when the clamping plate 54 moves under the action of the threaded rod 53, it will drive the chute 55 to slide synchronously on the outer surface of the slide bar 56, which can play a role in limiting the clamping plate 54; One end of the threaded rod 53 is fixedly connected to an operation block 57. Protrusions are arranged on the outer surface of the operation block 57. By arranging the operation block 57, rotating the operation block 57 can drive the threaded rod 53 to rotate. At the same time, protrusions are arranged on the outer surface of the operation block 57, which can effectively increase the friction force on the outer surface of the operation block 57 and has an anti-slip effect when rotating the operation block 57.

[0030] Refer to Figure 2 and Figure 3As shown, a nut 58 is threadedly connected to the outer surface of the threaded rod 53. The nut 58 is arranged between the side plate 52 and the clamping plate 54. By providing the nut 58 and rotating the nut 58 so that one side of the nut 58 abuts against one side of the side plate 52, the end of the threaded rod 53 can be limited, which helps prevent the clamping of the connecting pipe 4 by the clamping plate 54 from loosening. Rubber plates 59 are provided on the sides of the two clamping plates 54 that are close to each other. One side of the rubber plate 59 is fixedly connected to one side of the clamping plate 54. By providing the rubber plates 59, the rubber plates 59 can be used to abut against the outer surface of the connecting pipe 4 instead of one side of the clamping plate 54, thereby increasing the friction between the clamping plate 54 and the connecting pipe 4 and making the clamping of the connecting pipe 4 by the clamping plate 54 more stable.

[0031] Referring to Figure 2 and Figure 4 As shown, the positioning device 6 includes two threaded pins 61. One ends of the two threaded pins 61 are symmetrically and fixedly connected to one side of the housing 1. A stopper 62 is rotatably connected to the outer surface of the threaded pin 61. One side of the stopper 62 abuts against one side of the housing 1. A threaded hole block 63 is threadedly connected to the outer surface of the threaded pin 61. The threaded hole block 63 is arranged on one side of the stopper 62. By providing the stopper 62 and rotating the stopper 62, the stopper 62 can block the filter element 2. Then, by rotating the threaded hole block 63 so that one side of the threaded hole block 63 presses against the stopper 62 until one side of the stopper 62 completely abuts against one side of the housing 1, the stopper 62 can be fixed. Thus, the stopper 62 can position the filter element 2, which helps prevent the filter element 2 from easily detaching from the housing 1.

[0032] Referring to Figure 2 and Figure 4 As shown, a rubber pad 64 is arranged between the threaded hole block 63 and the stopper 62. One side of the threaded hole block 63 is fixedly connected to one side of the rubber pad 64. The outer surface of the threaded pin 61 is inserted into the inner wall of the gasket. By providing the rubber pad 64, the rubber pad 64 can be used to abut against one side of the stopper 62 instead of one side of the threaded hole block 63, which can make the fixation of the stopper 62 tighter. One end of the threaded pin 61 is fixedly connected to a round block 65. The outer diameter of the round block 65 is larger than the outer diameter of the threaded pin 61. By providing the round block 65, the end of the threaded pin 61 can be blocked, which helps prevent the threaded hole block 63 from detaching from the threaded pin 61 due to misoperation.

[0033] Working principle: When auxiliary fixation is required between the connecting pipe 4 and the pipes of the air duct system, rotate the operating block 57 to drive the threaded rod 53 to rotate. The threaded rod 53 will expand and contract on the inner wall of the side plate 52. Limited by the slide bar 56 and the chute 55, the threaded rod 53 will drive the clamping plate 54 to move synchronously until the rubber plates 59 on one side of the two clamping plates 54 completely clamp the connection between the connecting pipe 4 and the pipes of the air duct system. Then rotate the nut 58 so that one side of the nut 58 abuts against one side of the side plate 52, then the end of the threaded rod 53 can be limited, which is beneficial to prevent the clamping of the connecting pipe 4 by the clamping plate 54 from loosening, and then the auxiliary fixation between the connecting pipe 4 and the pipes of the air duct system can be carried out, which is beneficial to prevent the occurrence of gaps at their connection and ensure the normal operation of the air duct system; When positioning the filter element 2 is required, rotate the stop block 62 so that the stop block 62 can block the filter element 2, and then rotate the threaded hole block 63 so that the rubber pad 64 on one side of the threaded hole block 63 presses against the stop block 62 until one side of the stop block 62 is completely in contact with one side of the housing 1, then the stop block 62 can be fixed. Furthermore, the stop block 62 can position the filter element 2, which is beneficial to prevent the filter element 2 from easily detaching from the housing 1.
