[0029] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0030] like Figure 1 As shown in FIG. 1 , an automobile fuel filter device that is easy to install according to the present invention comprises a filter body 1, wherein the top and bottom of the filter body 1 are both connected with an oil pipe 2, as shown in FIG. Figure 6 As shown, the ends of the oil pipe 2 away from the filter body 1 are connected to a connecting hose 14, and the inner diameter of the connecting hose 14 is larger than the outer diameter of the connecting pipe, ensuring that the connecting hose 14 is on the outside when the connecting hose 14 is connected to the external connecting pipe. A fixing ring 3 is also provided at the end of the oil pipe 2 away from the filter body 1, and the connecting hose 14 is located in the middle of the fixing ring 3. The height of the fixing ring 3 is not greater than the height of the connecting hose 14, ensuring that the connecting hose 14 can still be stably connected to the external connecting pipe when it is deformed.

[0031] like Figure 3 As shown, the middle of the fixing ring 3 is opened and a thread groove 4 is opened on the top, a gear groove 6 is opened on one side of the thread groove 4, and a limit groove 5 is opened on the other side of the thread groove 4. A fastening rope 9 is arranged in the fixing ring 3. Figure 5 As shown, the inner side of the fastening rope 9 is set to a flat state, such as Figure 2As shown, two moving blocks 7 that move along the thread groove 4 are arranged on the top of the fixing ring 3, and a limiting block 10 that is slidably arranged with the limiting groove 5 is fixed at the bottom of the moving block 7. The stability of the position of the moving block 7 is ensured by the sliding arrangement between the limiting block 10 and the limiting groove 5. The bottoms of the two moving blocks 7 are respectively fixedly connected to the head and tail ends of the fastening rope 9 through connecting rods 8. The connecting rod 8 connected to the head end of the fastening rope 9 is arranged as an L-shaped rod, and the connecting rod 8 connected to the tail end of the fastening rope 9 is arranged as a vertical rod. The L-shaped connecting rod 8 connected to the head end of the fastening rope 9 makes There is a certain distance between the moving block 7 and the connecting hose 14, which facilitates the movement of the moving block 7. The moving block 7 at the head end of the connecting fastening rope 9 moves to drive the fastening rope 9 to move, thereby bundling the connecting hose 14, thereby achieving a sealed connection between the connecting hose 14 and the external connecting pipe. At the same time, the fastening rope 9 with a flat inner side increases the contact area between the fastening rope 9 and the connecting hose 14, thereby reducing the pressure and avoiding damage to the connecting hose 14 when the fastening rope 9 is bundled with the connecting hose 14, thereby increasing the service life of the device.

[0032] like Figure 4 As shown, a transmission rod 11 is rotatably provided on the moving block 7, a fixed cylinder 12 is fixed at the end of the transmission rod 11, and a gear 13 meshing with the gear groove 6 is provided on one side of the fixed cylinder 12, and a fixed block embedded in the moving block 7 is slidably provided on the top of the transmission rod 11, and the fixed block is set as a square block. The embedded square fixed block allows the transmission rod 11 to rotate when the fixed block is separated from the moving block 7, and the transmission rod 11 is fixed when the fixed block is embedded in the moving block 7. The movement of the moving block 7 first drives the fastening rope 9 to bind the connecting hose 14, and then the transmission rod 11 drives the gear 13 to mesh with the gear groove 6 to connect the connecting hose 14 to the external connecting pipe, thereby completing the installation of the filter body 1.

[0033] The gear 13 is arranged along the circumferential surface of the fixed cylinder 12 at 72°, and both sides of the fixed cylinder 12 abut against the inner wall of the thread groove 4. The position of the fixed cylinder 12 is limited by both sides of the fixed cylinder 12 abutting against the inner wall of the thread groove 4, thereby further increasing the stability of the position of the moving block 7. At the same time, the gear 13 is arranged along the circumferential surface of the fixed cylinder 12 at 72° to ensure that both sides of the fixed cylinder 12 can abut against the inner wall of the thread groove 4, thereby ensuring the stability of the device. There are two gear grooves 6, each of which is arranged at 90° along the side of the thread groove 4, and the two gear grooves 6 correspond to the positions of the two ends of the fastening rope 9 respectively. By setting two gear grooves 6, a large number of useless gear grooves 6 can be avoided. Since the outer diameter size variation range of the external connecting pipe will not be too large, the fastening rope 9 will not be displaced too far when bundling the connecting hose 14. Therefore, it is sufficient to set two gear grooves 6 with a smaller range to reduce the number of steps.

[0034] When in use, insert the external connecting pipe into the connecting hose 14, move the moving block 7 connected to the head end of the fastening rope 9 to drive the fastening rope 9 to move until it can no longer move, lift the fixed block to disengage it from the moving block 7, rotate the fixed block to drive the transmission rod 11 to rotate, thereby driving the gear 13 to engage with the gear groove 6, press the fixed block to embed it in the moving block 7 so that the transmission rod 11 is limited, and then complete the installation of the filter body 1. The operation is simple and stable, and unnecessary time is avoided.

[0035] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
