One end of the filter body is limitedly slid in the grille frame through a slider through a sliding groove, and the filter body is pressed against the limit position by the spring elastic force at the bottom of the limit support plate to ensure the stability of the filter body after installation. The rotating handle rotates the gear to drive the drive arm and the plug-in rod to extend and retract from the two ends of the grille frame inside and outside, which is easy to disassemble and assemble, and the filter body can be quickly replaced, which brings convenience to the replacement of the filter body and is conducive to improving work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a central air-conditioning filter that can be quickly disassembled and assembled, comprising a grille frame and a filter body, the inner cavity of the grille frame is provided with a filter body through a sliding groove, the inner bottom of the sliding groove is connected to a limiting support plate for pressing against the filter body through a spring, and a driving plug-in structure is provided in the upper and bottom ends of the grille frame, and the plug-in rods on both ends of the driving plug-in structure pass through the grille frame and are plugged into an external air-conditioning installation frame.

[0007] As a preferred solution, the top and bottom of the filter body are provided with sliding blocks, and the filter body slides in the grille frame through the sliding groove; a pull handle is provided on one end of the filter body.

[0008] As a preferred embodiment, the driving plug-in structure includes a plug-in rod, a driving arm and a gear. The plug-in rod is fixedly mounted on the outer end of the driving arm. The driving arm slides in a limited movable cavity opened in the upper and bottom ends of the grille frame. A gear is installed in the middle of the limited movable cavity through a rotating shaft, and the driving arm is provided with a rack that is meshed with the gear.

[0009] As a preferred solution, the rotating shaft of the gear passes through the grille frame and is connected to a rotating handle, and the plug-in rod rotates the gear through the rotating handle to drive the driving arm to extend and retract inward and outward at both ends of the grille frame.

[0010] As a preferred solution, a rectangular vent is provided on the outer side of the grille frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the utility model is installed and used, one end of the filter body is inserted into the grille frame from the sliding groove, so that the slider at the bottom of the filter body is pressed and slid on the limit support plate, and the filter body is pressed against the sliding groove of the grille frame by the elastic force of the spring at the bottom of the limit support plate, and the limit support plate is limited to ensure the stability of the filter body after installation. After assembling the filter body and the grille frame, align the grille frame with the air conditioner installation frame, rotate the handle to rotate the gear to drive the drive arm and the plug rod to extend outward from the inside of the two ends of the grille frame, so as to be plugged into the plug holes on the inner side of the two ends of the air conditioner installation frame; it can facilitate the installation of the grille frame on the space installation frame, and provide users with disassembly and assembly efficiency.

[0013] When the filter needs to be cleaned or replaced, first rotate the handle to rotate the gear to drive the drive arm and the connecting rod to retract inward from both ends of the grille frame, remove the grille frame, and then grab the pull handle to pull the filter body to slide outward from the sliding groove through the slider; it is convenient to pull the filter body out from the inside of the grille frame to complete the disassembly and assembly of the filter body; the filter body can be quickly replaced, and it is relatively convenient to disassemble or install, which shortens the time for replacing the filter body, brings convenience to replacing the filter body, and is conducive to improving work efficiency.
