Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-5 This is the first embodiment of the present utility model, which provides a tubular filter screen limiting device, including a base plate 1 and a filter screen body 2. A positioning groove 3 is provided on the top of the base plate 1, and the filter screen body 2 is placed on the top of the base plate 1. The shape of the bottom of the filter screen body 2 corresponds to the shape of the positioning groove 3. Mounting holes 4 are provided at the four corners of the top of the base plate 1, and a receiving groove 5 is provided inside the base plate 1. The receiving groove 5 is equipped with a limiting mechanism 6 inside; A drive mechanism 7 is provided on the right side inside the receiving slot 5.

[0022] Specifically, the filter body 2 is accurately positioned by the positioning groove 3, and the limiting mechanism 6 cooperates with the driving mechanism 7 to achieve stable fixation of the filter body 2. The structure is simple, easy to operate, and improves the reliability and stability of the filter body 2 installation.

[0023] Furthermore, the top of the base plate 1 is provided with a positioning groove 3 for placing the filter body 2, and the receiving groove 5 is provided with a limiting mechanism 6 and a driving mechanism 7. The driving mechanism 7 drives the limiting mechanism 6 to move, thereby limiting and fixing or releasing the filter body 2.

[0024] Example 2 The second embodiment of this utility model provides a tubular filter screen limiting device. The limiting mechanism 6 includes a gear disk 601, a guide groove 602, and a slider 603. The gear disk 601 is placed inside the receiving groove 5. The bottom of the gear disk 601 is rotatably connected to the bottom of the receiving groove 5. Guide grooves 602 are provided at the four corners of the top of the gear disk 601. The guide grooves 602 are all arc-shaped. The sliders 603 are placed inside the guide grooves 602. The sliders 603 are slidably connected to the inside of the guide grooves 602. The four corners of the top of the receiving groove 5 are provided with stroke grooves 604. The positions of the stroke grooves 604 correspond to the positions of the guide grooves 602. The top of the sliders 603 are slidably connected to the inside of the stroke grooves 604. The side of the sliders 603 near the positioning groove 3 is fixedly connected with a fixing rod 605. The end of the fixing rod 605 away from the sliders 603 passes through and extends out of the surface of the base plate 1. Fixing holes 606 are provided at the four corners of the bottom of the filter body 2, and the fixing holes 606 are used in conjunction with the fixing rods 605.

[0025] Specifically, by setting the limiting mechanism 6, the linkage between the gear disk 601 and the slider 603 can be used to make the fixing rod 605 accurately inserted into the fixing hole 606 at the bottom of the filter body 2, so as to achieve stable positioning and quick installation of the filter body 2.

[0026] Furthermore, when the gear disk 601 rotates, since the slider 603 is slidably connected to the inside of the stroke groove 604, the slider 603 can only move along the stroke groove 604. When the gear disk 601 rotates, the slider 603 will drive the fixed rod 605 to move along the stroke groove 604 towards the positioning groove 3 due to the curvature of the guide groove 602. When the fixed rod 605 is inserted into the corresponding fixing hole 606, the bottom of the filter body 2 is fixed.

[0027] Example 3 The third embodiment of this utility model provides a tubular filter screen limiting device. The driving mechanism 7 includes a rack 701 and a lead screw 702. The rack 701 is placed on the right side of the gear disk 601. The bottom of the rack 701 is slidably connected to the bottom of the receiving groove 5. The gear disk 601 and the rack 701 are meshed. The lead screw 702 is placed on the right side of the gear disk 601. Both the front and rear ends of the lead screw 702 are rotatably connected to the surface of the receiving groove 5. The rack 701 is threadedly connected to the surface of the lead screw 702. A first bevel gear 703 is fixedly connected to the front end of the lead screw 702, and a second bevel gear 704 is provided at the front end of the first bevel gear 703. The top of the second bevel gear 704 is rotatably connected to the top of the receiving groove 5, and the first bevel gear 703 and the second bevel gear 704 are meshed together. The top of the second bevel gear 704 is fixedly connected to a sleeve rod 705. The top of the sleeve rod 705 passes through and extends out of the top of the base plate 1. An extension rod 706 is placed inside the sleeve rod 705. The extension rod 706 is slidably connected to the inside of the sleeve rod 705. A rotating block 707 is fixedly connected to the top of the extension rod 706.

[0028] Specifically, by setting up the drive mechanism 7, the linkage transmission of the lead screw 702, rack 701, first bevel gear 703 and second bevel gear 704 can be used to precisely control the action of the limit mechanism 6, realize the rapid and reliable fixation of the filter body 2, and improve the ease of operation and the stability of the device.

[0029] Furthermore, the extension rod 706 is pulled out from inside the sleeve rod 705, and then the extension rod 706 is rotated using the rotating block 707. The extension rod 706 drives the second bevel gear 704 to rotate through the sleeve rod 705. The rotation of the second bevel gear 704 drives the first bevel gear 703 to rotate. The first bevel gear 703 drives the lead screw 702 to rotate. The lead screw 702 drives the rack 701 to move. The rack 701 drives the gear disk 601 to rotate.

[0030] Working principle: In use, first, install the base plate 1 in a suitable position through the mounting hole 4. Then, insert the bottom of the filter body 2 into the positioning groove 3. Next, pull the extension rod 706 out from the sleeve rod 705. Then, use the rotating block 707 to rotate the extension rod 706. The extension rod 706 drives the second bevel gear 704 to rotate through the sleeve rod 705. The rotation of the second bevel gear 704 drives the first bevel gear 703 to rotate. The first bevel gear 703 drives the lead screw 702 to rotate. The lead screw 702 drives the rack 701 to move. The rack 701 drives the gear disk 601 to rotate. Since the slider 603 is slidably connected to the inside of the stroke groove 604, the slider 603 can only move along the stroke groove 604. When the gear disk 601 rotates, the slider 603 will drive the fixing rod 605 to move along the stroke groove 604 towards the positioning groove 3 due to the curvature of the guide groove 602. When the fixing rod 605 is inserted into the corresponding fixing hole 606, the bottom of the filter body 2 is fixed.

[0031] In summary, by using a combination of a base plate 1, filter body 2, positioning groove 3, mounting hole 4, receiving groove 5, limiting mechanism 6, gear disk 601, guide groove 602, slider 603, stroke groove 604, fixing rod 605, fixing hole 606, drive mechanism 7, rack 701, lead screw 702, first bevel gear 703, second bevel gear 704, sleeve rod 705, extension rod 706, and rotating block 707, the problem of existing equipment often using a fixed connection structure during installation, requiring the disassembly of multiple fasteners or the entire structure when inspecting or replacing the filter, resulting in complex operation, time-consuming and labor-intensive work, and easily causing inaccurate filter positioning or unstable installation, affecting the filtration effect, is solved.
