In other embodiments, the screw sleeve 2 can also be installed through other clamping structures to complete the installation of the utility model. These are all prior arts and will not be repeated here.

[0035] The clamping structure includes a mounting plate 4, a clamping wheel 10 and a rotating rod 16. The mounting plates 4 are fixed at both ends of one side of the screw sleeve 2. The two mounting plates 4 are rotatably connected to the side close to each other by the rotating rod 16. The clamping wheel 10 is fixed to the outside of the rotating rod 16. The point between the rotating rod 16 and the clamping wheel 10 deviates from the center of the clamping wheel 10, so that the clamping structure can complete the installation of the filter steel mesh 1.

[0036] The locking structure includes a worm wheel 11, a worm 12, a connecting block 13, a connecting rod 14 and a handle 15. The worm wheel 11 is fixed to one end of the outer side of the rotating rod 16. The connecting blocks 13 are fixed to the top and bottom of one side of one mounting plate 4. The two connecting blocks 13 are rotatably connected to the side close to each other. The worm 12 and the worm wheel 11 are meshed and connected. The connecting rod 14 is fixed to the bottom of the worm 12. The handle 15 is fixed to the bottom of the connecting rod 14. The connecting rod 14 and one of the connecting blocks 13 are slidably connected, so that the locking structure can drive the rotating rod 16 to rotate and adjust the angle of the rotating rod 16.

[0037] The positioning structure includes a fixing sleeve 5, a connecting plate 6, a handle 7, a spring 8 and an insertion rod 9.

[0038] A plurality of circular holes are evenly formed on the outer side of the fixing sleeve 5 , and the inner diameters of the plurality of circular holes are equal to the outer diameter of the insertion rod 9 , so that the insertion rod 9 and the fixing sleeve 5 can be slidably connected.

[0039] The outer side of the clamping wheel 10 is provided with anti-skid grooves, so that the clamping wheel 10 can stably clamp the fixing rod 3.

[0040] The screw sleeve 2 is made of a high-strength, corrosion-resistant and lightweight material, which improves the load-bearing capacity and service life of the filter screen.

[0041] The utility model provides a detachable filter screen, and the device is designed with a clamping structure, so that the device is easy to connect to other filter devices, thereby reducing installation time and cost without spending a lot of time and effort;

[0042] The device is designed with a locking structure and a positioning structure so that when the filter needs to be cleaned or replaced, the filter can be easily removed and reinstalled, reducing the difficulty and cost of maintenance. The user can easily complete the maintenance work without the help of professionals.

[0043] The use process of a detachable filter screen provided by the utility model is as follows: when the user needs to disassemble the device, he first pulls open the handle 7, thereby driving the insertion rod 9 to stretch the spring 8, and then makes one side of the insertion rod 9 slide and connect on the inner side of the fixing sleeve 5, thereby detaching from the fixing sleeve 5, and then the user rotates the turning handle 15, and the rotation of the turning handle 15 drives the connecting rod 14 to rotate, thereby driving the worm 12 to rotate. Since one side of the worm 12 is meshedly connected with the worm wheel 11, the rotation of the worm 12 drives the worm wheel 11 to rotate, and the rotation of the worm wheel 11 drives the rotating rod 16 to rotate. A clamping wheel 10 is fixed on the outer side of the rotating rod 16, and the connection point of the clamping wheel 10 and the rotating rod 16 deviates from the center of the clamping wheel 10, so that the clamping wheel 10 deviates from the clamping of the fixing rod 3 when rotating along the rotating rod 16, thereby causing the screw sleeve 2 and the clamping wheel 10 to detach from the clamping of the fixing rod 3, so that the user can The filter mesh 1 can be held to separate from the contact with the screw sleeve 2, which is convenient for disassembly and cleaning of the filter mesh 1, and is convenient for disassembly and reinstallation of the filter mesh, reducing the difficulty and cost of maintenance. The user can easily complete the maintenance work without the help of professionals. After cleaning, when the filter mesh 1 needs to be reinstalled, the user only needs to align the fixing rod 3 between the two mounting plates 4, and then place the filter mesh 1 on the top of the screw sleeve 2, continue to pull open the handle 7, thereby driving the insertion rod 9 to stretch the spring 8, and then disengage from the fixing sleeve 5, and then rotate the handle 15, thereby driving the clamping wheel 10 to rotate, so that the clamping wheel 10 and the screw sleeve 2 tightly clamp the fixing rod 3, the user releases the handle 7, and under the elastic force of the spring 8, pulls the insertion rod 9 to slide inside the connecting plate 6, and then restores the plug connection with the fixing sleeve 5, thereby improving the clamping stability of the device.

[0044] In summary, the utility model is of great significance in improving filtration efficiency, reducing maintenance difficulty, reducing leakage risk, improving filtration effect, enhancing equipment reliability and improving user experience.
