[0002] Central air conditioning is a multi-split system, which consists of an outdoor unit and multiple indoor units. It can provide cooling or heating for multiple rooms at the same time, and deliver hot and cold air into each room through air ducts and air vents. The indoor unit of the central air conditioner is generally hidden in the ceiling, and the air conditioner needs to be supported and installed during installation.

[0003] However, most of the existing mounting brackets rely on installers to fix the air conditioner on the ceiling only with screws and fixing plates. Due to the heavy weight of the air conditioner, the positions of both sides cannot be adjusted at the same time, so that the indoor unit of the air conditioner is prone to tilt and fall off during installation, causing serious losses and injuries to personnel, and the safety is low;

[0004] Moreover, there are many types of air conditioners on the market with different sizes. The existing mounting brackets are designed for fixed length and cannot be adjusted in width. Moreover, the indoor unit of the air conditioner can only use the mounting bracket that is compatible with it, resulting in poor applicability of the existing brackets when used.

[0012] Preferably, the bottom of the worm is rotatably connected to a bearing seat, and the bearing seat is used in conjunction with the worm.

[0013] Preferably, there are sliders on both sides of the moving rod, and the fixed plate, the rotating rod, the movable plate and the moving rod are used in conjunction with each other.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model can make the bottom plate and the pull-out plate on which the air conditioner is placed move upward synchronously under force through the design of the lifting mechanism, and lift and clamp the air conditioner so that it is fixed to the ceiling.
