[0002] The panel of the air conditioner is connected to the middle frame through a connecting bracket, and the connecting bracket is connected to the driving component through a rotating shaft, and then the driving component drives the opening and closing of the panel through the rotating shaft and the connecting bracket. The connecting brackets are arranged at both ends of the panel, and the rotating shaft is arranged at one end of the connecting bracket. Figure 2 As shown, when the rotating shaft is set on one side of the middle frame, rotating shaft holes corresponding to the rotating shaft are set at both ends of the middle frame, and the rotating shaft is inserted into the rotating shaft hole. When the panel is rotated, the rotating shaft rotates in the rotating shaft hole to realize the opening and closing of the panel.

[0003] When the shaft is set on one side of the panel, such as Figure 1 As shown, the connecting bracket is connected to the support link via a rotating shaft, and the support link is fixed on the panel, that is, the connecting bracket is connected to the panel via the rotating shaft, so that the connecting bracket drives the panel to open and close.

Summary of the invention

[0005] In view of this, the present invention aims to provide a panel support structure and an air conditioner to solve the problem in the prior art that the upper limit of the rotating shaft in the left and right directions is insufficient and is prone to left and right shaking.

A first rotating shaft 41 is set at one end of the connecting bracket 4 connected to the panel 2, and a locking structure 1 is installed on the panel 2 in a detachable connection corresponding to the axial end of the first rotating shaft 41. The locking structure 1 is used to prevent the first rotating shaft 41 from moving in the axial direction, avoiding the connecting bracket 4 from shaking left and right, thereby improving the connection stability between the connecting bracket 4 and the panel 2.

[0053] Furthermore, the connecting bracket 4 includes a supporting link 26 and a movable link 25. The supporting link 26 is fixed on the panel 2.
