When the lock tongue rotates 90° along the axis, the straight-shaped boss falls back to the bottom of the cross groove. At this time, under the tension of the spring, the lock buckle shaft and the rivet column have no relative movement and remain in a locked state. By analogy, when the lock tongue continues to rotate along the axis of the rivet column to 180°, 270°, and 0°, the lock buckle can remain in a locked state, so that the dust removal net body and the outer frame can be locked together. When the dust removal net body needs to be disassembled, the lock buckle shaft rotates 90 degrees to the right to remove the dust removal net body from the outer frame, thereby achieving the effect of flexibly fixing and disassembling the dust removal net, and facilitating the cleaning and maintenance of the dust removal net.

The fixing mechanism 4 includes a locking tongue 41, the locking tongue 41 is fixedly connected to both sides of the dust removal net body 2, a locking handle 42 is connected through the surface of the locking tongue 41, a flat boss 46 is installed at the bottom of the locking tongue 41, one end of the locking handle 42 is fixedly connected to a locking shaft 43, the surface of the locking shaft 43 is connected through the limiting component 44, and the surface of the locking shaft 43 is connected through the limiting component 44. A spring 45 is connected, the lock shaft 43 passes through the notch inside the outer frame 1, the limiting component 44 includes a straight knurled sleeve 443, the straight knurled sleeve 443 is sleeved on the surface of the lock shaft 43, one end of the straight knurled sleeve 443 is fixedly connected with a rivet column 440, one end of the straight knurled sleeve 443 is fixedly connected with a knurled groove 444, the limiting component 44 includes a straight knurled sleeve 443, the straight knurled sleeve 443 is sleeved on the surface of the lock shaft 43, one end of the straight knurled sleeve 443 is fixedly connected with a rivet column 440, and one end of the straight knurled sleeve 443 is fixedly connected with a knurled groove 444;

[0027] Specifically, before assembly, the lock shaft 43 is first inserted into the rivet column 440, and the spring 45 is put on the lock shaft 43 to ensure that the spring 45 can be stuck on the lock shaft 43. Under the action of the spring 45, the lock shaft 43 is in the initial state, wherein the straight boss 46 is stuck in the cross groove 441. When the external force moves the lock tongue 41 or the lock handle 42 is lifted and rotated, the straight boss 46 climbs up from the bottom of the cross groove 441 and stays on the raised platform 442. When the lock tongue 41 rotates 90° along the axis, the straight boss 46 46 falls back to the bottom of the cross groove 441. At this time, under the pulling force of the spring 45, the locking shaft 43 and the rivet column 440 have no relative movement and remain in a locked state. Similarly, when the locking tongue 41 continues to rotate along the axis of the rivet column 440 to 180°, 270°, and 0°, the lock can remain in a locked state, so that the dust removal net body 2 and the outer frame 1 can be locked together. When the dust removal net body 2 needs to be disassembled, the locking shaft 43 is rotated 90 degrees to the right to remove the dust removal net body 2 from the outer frame 1.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the assembly mechanism 3 includes a fixed column 30, the fixed column 30 is fixedly connected to one side of the outer frame 1, the surface of the fixed column 30 is fixedly connected to a rear section 31, one end of the rear section 31 is sleeved with a compression spring 32, the surface of the rear section 31 is fixedly connected to a clamping disk 33, the surface of the clamping disk 33 is plugged with a connecting tube 34, one end of the connecting tube 34 is fixedly connected to a mounting column 35, a blocking member 36 is installed inside the connecting tube 34, the blocking member 36 includes a plurality of blocking sheets 362 installed on the inner tube wall of the connecting tube 34, the blocking sheets 362 are matched with the clamping disk 33 one by one, the blocking sheets 362 are installed on the inner tube wall of the connecting tube 34 through a movable shaft 360, and a resisting block 361 is provided at the front edge of the blocking sheet 362;

[0030] Specifically, when multiple dust removal nets need to be spliced, the rear section 31 is inserted into the inner cylinder cavity of the connecting cylinder 34, and the slope surface of the clamping plate 33 conflicts with the blocking piece 362, so that the blocking piece 362 is folded with the movable shaft 360 as the axis, so that the clamping plate 33 pushes the blocking piece 362 in turn, and the rear section 31 is extended into the connecting cylinder 34 as a whole. After the docking is completed, the non-insertion end disk surface of the clamping plate 33 conflicts with the rear surface of the blocking piece 362, and the blocking piece 362 is a one-way folding structure, and the conflicting block 361 makes the blocking piece 362 can only flip backwards, so that the blocking piece 362 forms a blocking structure for the inserted card plate 33 to prevent the rear section 31 from being separated from the connecting tube 34. The resistance block 361 is installed in a plug-in manner. When the entire dust removal net needs to be disassembled, the resistance block 361 is pulled out and disassembled, so that the blocking piece 362 can be freely flipped along the movable axis 360, thereby separating the rear section 31 from the connecting tube 34. A compression spring 32 is provided to buffer the rear section 31 and reduce the risk of the rear section 31 and the connecting tube 34 being broken and separated by external force.

[0031] The following is a detailed description of the working principle of the environmental protection dust removal net.

[0032] like Figure 1-5 As shown, when an external force moves the lock tongue 41 or lifts the lock handle 42 to rotate, the straight boss 46 climbs up from the bottom of the cross groove 441 and stays on the raised platform 442. When the lock tongue 41 rotates 90° along the axis, the straight boss 46 falls back to the bottom of the cross groove 441. At this time, under the pulling force of the spring 45, the lock shaft 43 and the rivet column 440 have no relative movement and remain in a locked state. By analogy, when the lock tongue 41 continues to rotate along the axis of the rivet column 440 to 180°, 270°, and 0°, the lock can remain in a locked state. Thereby, the dust removal net body 2 and the outer frame 1 can be locked together. When the dust removal net body 2 needs to be disassembled, the locking shaft 43 is rotated 90 degrees to the right to remove the dust removal net body 2 from the outer frame 1. When the entire dust removal net needs to be disassembled, the disassembly resistance block 361 is pulled out so that the blocking piece 362 can be freely flipped along the movable axis 360, thereby separating the rear section 31 from the connecting tube 34. A compression spring 32 is provided to buffer the rear section 31, thereby reducing the risk of the rear section 31 and the connecting tube 34 being broken and separated by external force.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
