DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1-6 As shown, a filter testing tool comprises a test bench 1 and a filter body 2, a positioning assembly is provided at the upper end of the test bench 1, the positioning assembly comprises a carrier 3 arranged on the top of the test bench 1 and used to support the filter body 2, a first linear guide rail 4 corresponding to the carrier 3 is provided at the top front end of the test bench 1, the carrier 3 is movably connected to the first linear guide rail 4, a bracket 5 is provided at the rear end of the top of the test bench 1, a handle 6 is movably connected to the upper end of the bracket 5, a connecting piece 13 is movably connected to the lower end side wall of the handle 6, a vertically arranged upright pole 12 is movably connected to the lower end of the connecting piece 13, a horizontally arranged pressing plate 7 for pressing the top of the filter body 2 is fixedly provided at the bottom of the upright pole 12;

[0029] It also includes a driving assembly for driving the carrier 3 to move forward and backward. The driving assembly includes a guide sleeve 8 fixedly arranged at one end of the pressure plate 7. There are two guide sleeves 8, which are symmetrically arranged on both sides of the rear end of the pressure plate 7. A guide column 9 is vertically fixed on the top of the test bench 1 and is matched with the guide sleeve 8 for movable guidance. The top of the guide column 9 is fixed to the upper end of the bracket 5. A spiral guide groove 15 is provided on the outer side of the lower end of the guide column 9. The inner wall of the guide sleeve 8 is fixed with an arc-shaped guide block 1 that is matched with the guide groove 15 for movable guidance. 7. A gear 10 is fixedly provided at the lower end of the guide column 9, and a rack 14 meshing with the gear 10 is provided at the rear end of the carrier 3. A second linear guide rail 11 is provided at the rear end of the bottom of the test bench 1. The rack 14 is movably guided by the second linear guide rail 11 and is configured so that when the guide block 17 moves downward, the gear 10 drives the rack 14 to move backward. A vertical groove 16 is provided at the lower end of the guide groove 15, and the vertical groove 16 is vertically arranged, and is configured so that when the guide block 17 moves to the vertical groove 16, the carrier 3 corresponds to the pressure plate 7 at this time.

[0030] Furthermore, a groove 18 adapted to the filter body 2 is provided on the top of the carrier 3, and a support plate 20 for supporting the filter body 2 is longitudinally movably connected to the inner upper end of the groove 18, and springs 19 are symmetrically provided at the four corners of the bottom of the support plate 20. A support column 21 for stopping the support plate 20 is provided at the inner bottom of the groove 18, and is configured so that when the pressure plate 7 moves down to the limit distance, the bottom of the support plate 20 just contacts the top of the support column 21.

[0031] It should be noted that the present invention is a filter test fixture. When in use, the carrier 3 is located at the front end of the top of the test bench 1 and is staggered with the pressure plate 7. The filter body 2 is placed on the upper end of the groove 18 at the top of the carrier 3 and supported by the support plate 20. Then, the handle 6 is pulled down to drive the pressure plate 7 downward through the connecting piece 13 and the vertical rod 12. The downward movement of the pressure plate 7 drives the guide sleeve 8 downward, and the guide sleeve 8 drives the guide block 17 downward. The guide block 17 drives the guide column 9 to rotate under the action of the guide groove 15. The guide column 9 drives the gear 10 to rotate, and the gear 10 drives the carrier through the rack 14. 3 moves backward. When the guide block 17 moves to the vertical slot 16, the carrier 3 moves below the pressure plate 7. When the pressure plate 7 continues to move downward, the guide block 17 moves downward in the vertical slot 16, and the guide column 9 remains stationary. Then the pressure plate 7 gradually presses the filter body 2, and the support plate 20 compresses the spring 19 when pressing. When it is completely pressed, the support plate 20 is stopped by the support column 21, and then the test work can be carried out. After the test is completed, the handle 6 can be pulled up to separate the pressure plate 7 from the filter body 2 and move the carrier 3 forward, and the filter body 2 can be lifted up by the spring 19 and then removed.
