[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter screen that is easy to fix with a frame, comprising two frames and two mesh bodies. Each mesh body includes a metal mesh and an outer edge frame. The outer edge frame is connected to the outer ring of the metal mesh. Both sides of the outer edge frame are sloped. The side surface of the frame is provided with a slot whose width is adapted to the width of the outer edge frame. A clamping strip is connected to the inner wall of the slot. A screw tube is fitted onto the surface of the outer edge frame. A fixing hole is provided on the surface of the frame. A fixing bolt passes through the fixing hole and the inside of the screw tube.

[0006] As a preferred embodiment of the present invention, which is easy to fix the frame of the filter, the bottom side of the pressing strip is set as an inclined surface, and the inclined surface of the bottom side of the pressing strip is adapted to the slope.

[0007] As a preferred embodiment of this utility model of a filter screen that is easy to fix with a frame, the screw tube, fixing hole and fixing bolt are provided in two sets, the screw tube and fixing hole correspond one-to-one, and the fixing bolt and screw tube are threaded together.

[0008] As a preferred embodiment of the present invention, which is easy to fix the frame, the two frames are connected by a hinge, and two fixing blocks are respectively connected to the surface of the two frames, and a first fixing screw hole is opened on the surface of each of the four fixing blocks.

[0009] As a preferred filter of this utility model that is easy to fix to the frame, the fixing blocks located on the two frame surfaces are arranged in a cross arrangement, and the central axes of the two first fixing screw holes on the surfaces of the two fixing blocks are in the same position.

[0010] As a preferred embodiment of the present invention, which is easy to fix the frame, the inner walls of the two frames are respectively connected to a fixing ear, and the surfaces of the two fixing ears are respectively provided with a second fixing screw hole.

[0011] As a preferred embodiment of this utility model for easy frame fixing of a filter, the two fixing ears and the second fixing screw hole are symmetrically arranged through the longitudinal section of the hinge.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: a filter screen that is easy to fix with a frame, comprising two frame frames 1 and two mesh bodies 2. The mesh body 2 includes a metal mesh 201 and an outer edge frame 202. The outer edge frame 202 is connected to the outer ring of the metal mesh 201. The two sides of the outer edge frame 202 are provided with slopes 3. The side surface of the frame frame 1 is provided with a slot 4 whose width is adapted to the width of the outer edge frame 202. The inner wall of the slot 4 is connected with a clamping strip 5. A screw tube 6 is fitted and installed on the surface of the outer edge frame 202. The surface of the frame frame 1 is provided with a fixing hole 7. A fixing bolt 8 passes through the fixing hole 7 and the inside of the screw tube 6.

[0018] Preferably, the bottom side of the pressing strip 5 is set as an inclined surface, and the inclined surface of the bottom side of the pressing strip 5 is adapted to the slope 3.

[0019] In practical use, as the outer frame 202 drives the metal mesh 201 to insert into the slot 4, the clamping strip 5 gradually weds into the slope 3 on the surface of the outer frame 202, thereby making it easy to clamp the mesh 2.

[0020] Preferably, there are two sets of screw tube 6, fixing hole 7 and fixing bolt 8, with screw tube 6 and fixing hole 7 corresponding one-to-one, and fixing bolt 8 and screw tube 6 being threadedly connected.

[0021] In practical use, when the fixing bolt 8 moves through the fixing hole 7 to the opening of the screw tube 6, it rotates. At this time, rotating the fixing bolt 8 can make threaded connection with the screw tube 6, so that the position of the mesh body 2 can be fixed through the threaded connection between the fixing bolt 8 and the screw tube 6.

[0022] Preferably, the two frame 1 are connected by a hinge 9, and two fixing blocks 10 are respectively connected to the surface of the two frame 1. Each of the four fixing blocks 10 has a first fixing screw hole 11.

[0023] In practical use, when the matching bolts pass through the first fixing screw holes 11 of a set of two intersecting fixing blocks 10, the two intersecting fixing blocks 10 can be fixed by threaded connection, thereby fixing the two frame blocks 1.

[0024] Preferably, the fixing blocks 10 located on the surfaces of the two frame blocks 1 are arranged in pairs and the central axes of the two first fixing screw holes 11 on the surfaces of the two fixing blocks 10 are in the same position.

[0025] Preferably, the inner walls of the two frame 1 are each connected to a fixing ear 12, and the surfaces of the two fixing ears 12 are each provided with a second fixing screw hole 13.

[0026] In practical use, after one of the frame 1 rotates 180° around the central axis of the hinge 9, the two sets of second fixing screw holes 13 can be aligned, so that the two frame 1 can be connected and fixed by bolts of appropriate size and threaded connection with the two sets of second fixing screw holes 13.

[0027] Preferably, the two fixing ears 12 and the second fixing screw hole 13 are symmetrically arranged through the longitudinal section of the hinge 9.

[0028] Working principle: During installation, the outer frame 202 is inserted into the slot 4. After the outer frame 202 is fully inserted into the slot 4, it can be wedge-tightened by the setting of the clamping strip 5. When the outer frame 202 drives the screw tube 6 to align with the fixing hole 7, the fixing bolt 8 is then moved through the fixing hole 7 to the opening of the screw tube 6 and rotated. When the fixing bolt 8 rotates, it can be threadedly connected with the screw tube 6, thus fixing the position of the outer frame 202, thereby realizing the connection between the frame 1 and the mesh 2. When the filter needs to change the application mode, one of the frame 1 can be pulled to rotate around the central axis of the hinge 9. After the frame 1 rotates 180°, the two sets of second fixing screw holes 13 can be aligned, so that the two frame 1 can be fixed by threaded connection between the size-adaptive bolt and the two second fixing screw holes 13.
