[0030] Reference Figure 1As shown, the present invention provides a technical solution: a waterproof sealed filter cavity, comprising a lower cavity 1 and an upper cover 2. The dimensions of the lower cavity 1 match those of the upper cover 2. Both sides of the lower cavity 1 are provided with wire holes 3. The surface of the upper cover 2 is provided with a sealing structure 4. The provision of the sealing structure 4 facilitates the use of a sealing gasket 406 to cover the connection between the upper cover 2 and the lower cavity 1, thereby preventing rainwater from entering the interior of the filter and thereby ensuring the normal operation of the filter. The surface of the lower cavity 1 is provided with an adjustment structure 5. The provision of the adjustment structure 5 facilitates the adjustment of the position of the filter mounting plate 53, thereby allowing the filter to be installed in different positions, thereby facilitating the installation of the filter.

[0031] The specific configuration and function of the sealing structure 4 and the regulating structure 5 will be described in detail below.

[0032] Reference Figure 2 - Figure 5 As shown, in this embodiment: the sealing structure 4 includes two brackets 401, and the two brackets 401 are fixedly connected to the surface of the upper cover 2. The surface of the bracket 401 slides through the limit rod 402, and one end of the limit rod 402 is fixedly connected to the driving plate 403, and the surface of the driving plate 403 is fixedly connected to the pin 404. The surface of the upper cover 2 is covered with two sealing covers 405, and the surface of the sealing covers 405 is glued with a sealing gasket 406. The surface of the sealing covers 405 is provided with two circular holes 407, and the size of the circular hole 407 is adapted to the size of the pin 404. The surface of the sealing cover 405 is fixedly connected to a guide arm 408, and the surface of the upper cover 2 is fixedly connected to two rectangular tubes 409. The size of the rectangular tubes 409 is adapted to the size of the guide arms 408. The guide arms 408 are inserted into the rectangular tubes 409. At this time, the sealing cover 405 will drive the sealing gasket 406 to cover the connection between the lower cavity 1 and the upper cover 2. The guide rods 55 limit the movement path of the sealing cover 405 and prevent the sealing cover 405 from deflecting during movement. The inner wall of the rectangular tube 409 is fixedly connected to a plurality of fixed rods 410. The arc surface of the fixed rods 410 is covered with cylinders 411. When the guide arms 408 move within the rectangular tube 409, they slide along the surface of the cylinders 411. The cylinders 411 rotate on the surface of the fixed rods 410 with the force of the movement of the guide arms 408. The cylinders 411 reduce the friction of the guide arms 408 when they move within the rectangular tube 409, thereby facilitating the movement of the guide arms 408. The arc surface of the latch 404 is covered with a spring 412, and the two ends of the spring 412 are fixedly connected to the latch 404 and the bracket 401 respectively. The limit rod 402 will move in the bracket 401 with the help of the contraction force of the spring 412. The spring 412 improves the stability of the latch 404 inserted into the circular hole 407, and prevents the limit rod 402 from shaking and causing the latch 404 to fall out of the circular hole 407, thereby ensuring the stability of the sealing gasket 406 covering the connection between the upper cover 2 and the lower cavity 1.

[0033] Reference Figure 6 As shown, the adjustment structure 5 specifically includes two rectangular boxes 51, each fixedly connected to either side of the lower chamber 1. A bidirectional screw 52 is rotatably connected to the inner wall of the rectangular box 51. One end of the bidirectional screw 52 extends through the rectangular box 51. Two mounting plates 53 are threadedly connected to the surface of the bidirectional screw 52. The surfaces of the mounting plates 53 are provided with mounting holes 54. Guide rods 55 are slidably passed through the surfaces of the two mounting plates 53. Both ends of the guide rods 55 are fixedly connected to the rectangular box 51. When the mounting plates 53 move, they slide along the surfaces of the guide rods 55. The guide rods 55 serve to limit the movement path of the mounting plates 53 and prevent them from rotating during movement. One end of the bidirectional screw 52 is fixedly connected to a circular plate 56. The arc surface of the circular plate 56 is fixedly connected to a plurality of round rods 57. Rotation of the round rods 57 drives the circular plate 56 to rotate, which in turn drives the bidirectional screw 52 to rotate. The round rods 57 facilitate the rotation of the circular plate 56, and thus the rotation of the bidirectional screw 52.

[0034] Working principle: when the upper cover 2 needs to be assembled with the lower cavity 1, first put the upper cover 2 on the lower cavity, and then pull the limit rod 402, the limit rod 402 moves and slides in the bracket 401, and the limit rod 402 will stretch the spring 412 when moving, and the limit rod 402 will drive the driving plate 403 to move when moving, and the movement of the driving plate 403 will drive the two latches 404 to move. When the latches 404 move to the appropriate position, use glue to stick the sealing gasket 406 to the surface of the sealing cover 405, and then insert the guide arm 408 into the rectangular tube 409. At this time, the sealing cover 405 will drive the sealing gasket 406 to cover the connection between the lower cavity 1 and the upper cover 2, and then push the sealing cover 405. The sealing cover 405 will drive the sealing gasket 406 to gradually cover the connection, and the guide arm 408 will slide in the rectangular tube 409 with the help of the force of the movement of the sealing cover 405. , the guide arm 408 moves in the rectangular tube 409 and slides along the surface of the cylinder 411, and the cylinder 411 rotates on the surface of the fixed rod 410 with the help of the force of the guide arm 408 moving. The cylinder 411 reduces the friction of the guide arm 408 when it moves in the rectangular tube 409, thereby facilitating the movement of the guide arm 408. When the sealing cover 405 moves to a suitable position, the sealing cover 405 drives the sealing gasket 406 to completely cover the connection between the upper cover 2 and the lower cavity 1, and then releases the limit rod 402. The limit rod 402 moves in the bracket 401 with the help of the contraction force of the spring 412, and the driving plate 403 drives the pin 404 to be inserted into the circular hole 407 with the help of the limit rod 402. The pin 404 reaches the position of limiting the sealing cover 405, thereby limiting the position of the sealing gasket 406, thereby sealing the connection between the upper cover 2 and the lower cavity 1.

[0035] When the filter cavity needs to be installed, first rotate the round rod 57. The rotation of the round rod 57 will drive the circular plate 56 to rotate. The rotation of the circular plate 56 will drive the bidirectional screw 52 to rotate. The rotation of the bidirectional screw 52 will drive the two mounting plates 53 to move at the same time with the help of the thread. When moving, the mounting plate 53 will slide along the surface of the guide rod 55. The guide rod 55 limits the moving path of the mounting plate 53 and prevents the mounting plate 53 from rotating when moving. When the mounting plate 53 is moved to a suitable position, the filter cavity is installed using bolts passing through the mounting holes 54.

[0036] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
