[0008] Preferably, the connection frame is located in the inner wall of the cavity and is fixedly connected with a plurality of connecting rods, and corresponding sides of the plurality of connecting rods are fixedly connected with threaded rings at the same time, and the inner wall of the threaded ring is threadedly connected with a screw.

[0009] Preferably, the top end wall of the screw extends to the inside of the through groove of the rotating drum.

[0010] Preferably, the screw is fixedly connected to a shift plate on the rod wall inside the rotating drum, a rectangular groove is opened on the inner wall of the rotating drum located at the through groove, and the shift plate is slidably arranged on the inner wall of the rotating drum located at the rectangular groove.

[0011] Preferably, the bottom end wall of the screw rod passes through the threaded ring and is fixedly connected to a baffle.

[0012] Preferably, the end of the clamping plate facing away from the torsion spring is configured as an arc surface, and the rotating handle is configured as a T-shaped rod.

[0013] Compared with the prior art, the present invention provides an air conditioning filter that is easy to install and has the following beneficial effects:

[0014] 1. The air conditioner filter that is easy to install is configured such that the connecting frame is placed on the inner wall of the air conditioner installation location, and the torsion spring can push the card plate to rotate along the rod wall of the fixed rod so that the card plate extends into the card slot inside the commercial central air conditioner. This allows the connecting frame to be stably placed inside the commercial central air conditioner, and the filter can be installed quickly and efficiently.

[0015] 2. The air-conditioning filter that is easy to install can drive the drum to rotate by turning the handle. The rotation of the drum can drive the pull rope to retract into the inside of the cavity and make the pull rope wrapped around the inside of the drum. The movement of the pull rope can pull the clamping plate to retract into the inside of the rectangular opening, which is convenient for the subsequent removal of the connecting frame and the filter.

[0016] 3. The air conditioning filter that is easy to install can rotate the screw through the dial plate when the drum rotates. The screw can rotate along the inner wall of the threaded ring, so that the screw can rotate with the drum without affecting the adjustment of the drum. After the drum stops, the internal friction of the screw locking arrangement in the threaded ring increases, which can fix the screw and the dial plate, and limit the drum to prevent the drum from rotating back and affecting the subsequent removal of the connecting frame.
