[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1-6 , an embodiment provided by the present utility model:

[0024] A filter installation base: It includes a bottom plate 1. A guide plate 2 is fixedly connected to the surface of the bottom plate 1. A slider 3 is slidably connected to the surface of the guide plate 2. A movable plate 4 is fixedly connected to the surface of the slider 3. A square nut 5 is fixedly connected to the bottom of the movable plate 4. A bidirectional lead screw 6 is rotatably connected to the surface of the bottom plate 1. A knob 7 is fixedly connected to the surface of the bidirectional lead screw 6. A guide block 8 is fixedly connected to the surface of the movable plate 4. A movable rod 9 is slidably connected to the surface of the guide block 8. A limit block 11 is fixedly connected to the surface of the movable rod 9. A return spring 10 is fixedly connected to the surface of the guide block 8. A spring piece 12 is fixedly connected to the surface of the limit block 11. A limit post 13 is fixedly connected to the surface of the movable plate 4. A filter body 14 is placed on the surface of the movable plate 4. This filter installation base does not use bolts to install the filter, but uses the cooperation of the limit block 11 and the limit post 13 to limit the filter body 14, thereby completing the fixed installation of the filter body 14, avoiding the phenomenon of the bolts for installing the filter body 14 being lost, thus avoiding the trouble of purchasing new bolts to install the filter body 14, saving time and effort. At the same time, the movable plate 4 can move on the slider 3, so that filters of different specifications and sizes can be installed, improving the adaptability of the filter installation base.

[0025] Further, a guide groove is provided on the surface of the guide plate 2. The slider 3 slides on the guide groove of the guide plate 2. The movable plate 4 slides on the surface of the guide plate 2 through the slider 3. There are two groups of movable plates 4, which are symmetrically distributed on the slider 3. The movable plate 4 will drive the guide block 8 and the limit post 13 to slide synchronously on the guide plate 2.

[0026] Further, the square nut 5 is threadedly connected to the surface of the bidirectional lead screw 6. The bidirectional lead screw 6 drives the square nut 5 to move through rotation. The maintenance personnel drive the bidirectional lead screw 6 to rotate through the knob 7. There are two groups of square nuts 5, and the moving directions of the two groups of square nuts 5 are opposite. The square nut 5 drives the movable plate 4 to move in opposite directions, so that the movable plates 4 approach or move away from each other, and the movable plate 4 changes the distance between the two limit posts 13, thereby facilitating the installation of filter bodies 14 of different specifications and sizes.

[0027] Further, a guide hole is provided on the surface of the guide block 8. The movable rod 9 slides on the guide hole of the guide block 8. The limit block 11 slides on the surface of the guide block 8 through the movable rod 9. Under the guidance of the movable rod 9, the limit block 11 will slide to contact and connect with the limit post 13.

[0028] Furthermore, one side of the reset spring 10 away from the guide block 8 is fixedly connected to the surface of the limit block 11. The elastic force of the reset spring 10 acts on the limit block 11, causing the limit block 11 to slide in the direction of the limit post 13. The limit post 13 also restricts the position of the limit block 11 on the movable plate 4.

[0029] Furthermore, a clamping groove is formed on the surface of the limit block 11. The limit post 13 is clamped and connected to the clamping groove of the limit block 11. Installation plates are arranged on both sides of the filter body 14, and installation holes are arranged on the installation plates. The limit post 13 passes through the installation holes of the installation plates of the filter body 14, and the limit post 13 restricts the position of the filter body 14 on the movable plate 4 through the installation holes of the installation plates of the filter body 14.

[0030] Furthermore, the bottom of the limit block 11 is in contact connection with the installation plate of the filter body 14. The limit block 11 restricts the position of the installation plate of the filter body 14 on the movable plate 4, thus completing the installation of the filter body 14 on the movable plate 4. A groove is formed at the bottom of the limit block 11, and the spring piece 12 is fixedly connected to the groove of the limit block 11. The spring piece 12 presses the installation plate of the filter body 14 on the limit block 11, improving the installation stability of the filter body 14 on the movable plate 4.

[0031] Working principle: Pull the movable rod 9 on the surface of the guide block 8 to make the limit block 11 break away from the limit post 13, then pass the limit post 13 through the installation hole on the installation plate of the filter body 14, release the movable rod 9. Under the elastic force of the reset spring 10, the limit block 11 will slide in the direction of the limit post 13. Dial the spring piece 12 upward at the bottom of the limit block 11 to make the limit post 13 be clamped and connected to the clamping groove of the limit block 11. The limit block 11 cooperates with the limit post 13 to restrict the filter body 14 on the surface of the movable plate 4, and the spring piece 12 presses the installation plate of the filter body 14 on the limit block 11, ensuring the stability of the spring piece 12 on the movable plate 4, avoiding installing the filter body 14 with bolts, thus avoiding the problem of bolt loss, and there is no need to repurchase or search for bolts to install the filter body 14, which is more time-saving and labor-saving.

[0032] Rotate the bidirectional lead screw 6 on the bottom plate 1 through the knob 7. The bidirectional lead screw 6 drives two square nuts 5 to move through rotation. The square nuts 5 drive two bidirectional lead screws 6 to slide on the surface of the guide plate 2. During the sliding process of the bidirectional lead screw 6, the distance between the two limit posts 13 is changed, so that the filter installation base can install filter bodies 14 of different models, improving the adaptability of the filter installation base.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
