DETAILED DESCRIPTION

[0019] In order to make those skilled in the art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0020] AsFigs. 1-3 As shown in the figure, the adjustable filter testing fixing device provided by this utility model includes a bottom shell 1, a support plate 2 is provided on the top of the bottom shell 1, two baffles 3 are fixed on the top outer wall of the support plate 2, and a partition 7 is provided between the two baffles 3. A nut 9 is fixed on one side outer wall of one of the baffles 3, and a screw 10 is threadedly connected inside the nut 9. A pressing plate 8 is bearing connected to one end of the screw 10, and the pressing plate 8 is fixed to one of the partitions 7.

[0021] Specifically, in this embodiment, a bottom shell 1 is included, and a support plate 2 is provided on the top of the bottom shell 1. Two baffles 3 are fixed on the top outer wall of the support plate 2. The two baffles 3 are located at both ends of the support plate 2, and evenly distributed partitions 7 are provided between the two baffles 3. The filter to be fixed is placed between the two partitions 7. A nut 9 is fixed on one side outer wall of one of the baffles 3. A screw 10 is threadedly connected inside the nut 9. A pressing plate 8 is bearing connected to one end of the screw 10. The pressing plate 8 is fixed to one of the partitions 7. When the screw 10 is rotated, the pressing plate 8 can push the baffle 3 fixed to it to move.

[0022] This utility model provides an adjustable filter testing fixing device. When the screw 10 rotates, it squeezes the extrusion plate 8, thereby fixing multiple filters placed between adjacent partitions 7. This achieves the effect of fixing multiple filters at the same time, which facilitates the sequential testing of multiple filters. At the same time, the position of the partition 7 is adjustable, which is convenient for fixing filters of various specifications.

[0023] In another embodiment of this utility model, a groove 5 is provided on the top outer wall of the support plate 2, and a uniformly distributed slider 6 is slidably connected inside the groove 5. The bottom of the partition plate 7 is fixed to the slider 6 to prevent the partition plate 7 from detaching from the support plate 2. A reference plate 4 is fixed to one end of the partition plate 7, and one side of the filter is close to the reference plate 4 so that the filter can be arranged neatly. A knob 11 is fixed to one end of the screw 10, and the knob 11 facilitates the rotation of the screw 10.

[0024] In another embodiment of this utility model, a central shaft 15 is fixed to the bottom outer wall of the support plate 2. The central shaft 15 is connected to the bottom shell 1 via a bearing, allowing the support plate 2 to rotate on the bottom shell 1. The bottom end of the central shaft 15 extends into the interior of the bottom shell 1 and a worm gear 17 is fixed thereon. A rotating shaft 14 is connected between the inner walls of the two sides of the bottom shell 1 via a bearing. A worm 16 is fixed to the outside of the rotating shaft 14. The worm 16 meshes with the worm gear 17. When the worm 16 rotates, it can drive the worm gear 17 and the rotating shaft 14 to rotate. A motor 18 is fixed to one side outer wall of the bottom shell 1. One end of the output shaft of the motor 18 is fixed to the rotating shaft 14. The motor 18 drives the rotating shaft 14 and the worm 16 to rotate, allowing the worm 16 to drive the worm gear 16 to rotate. The rotation of wheel 17, central shaft 15, and support plate 2 makes it easier to adjust the orientation of the filter fixed on support plate 2, thus facilitating the adjustment to the optimal testing position. Mounting ears 12 are fixed to the outer wall of the bottom shell 1, and mounting holes 13 are provided on the top outer wall of the mounting ears 12. The mounting holes 13 facilitate the fixing of the bottom shell 1, and the open mounting holes 13 allow for adjustment of the fixed position of the bottom shell 1. Support seats 19 are fixed to the top outer wall of the bottom shell 1. Preferably, there are four support seats 19, which are centrally symmetrically distributed around the central shaft 15. Support wheels 20 are connected to the internal bearings of the support seats 19. The support wheels 20 are located at the bottom of the support plate 2, making the rotation of the support plate 2 more stable.

[0025] Working principle: When multiple filters need to be fixed, the filters are placed on both sides of the partition plate 7, with one side of the filter close to the reference plate 4. Then, the screw 10 is rotated by the knob 11, causing the screw 10 to drive the pressing plate 8 to press the partition plate 7, thereby fixing the multiple filters between the partition plates 7. When the orientation of the filters needs to be changed, the rotating shaft 14 and the worm gear 16 are rotated by the motor 18, so that the worm gear 16 can drive the worm wheel 17 and the central shaft 15 to rotate, thereby changing the orientation of the filters fixed on the support plate 2.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
