Trundle control mechanism convenient to hide and used for mobile air conditioner

Abstract

The invention discloses a trundle control mechanism convenient to hide and used for a mobile air conditioner. The trundle control mechanism comprises an air conditioner shell and protection covers; afixed plate is installed below the air conditioner shell; rotary shafts penetrate through the surface of the fixed plate; gears are arranged on the outer sides of the rotary shafts; the protection covers are fixedly installed at the lower ends of the rotary shafts; wheels are arranged inside the protection covers; the upper end of the fixed plate penetrates through the surface of a rotary plate; asupporting rod is fixed to the upper surface of the rotary plate; a protection sleeve is installed at the tail end of the supporting rod; the supporting rod penetrates through the surface of the rotary plate; and a connection block is installed below the supporting rod. The trundle control mechanism convenient to hide and used for the mobile air conditioner can meet the three states of straight movement, turning and locking, and can move in various terrains conveniently, when a handle is outward, gasbags lose the limiting function for the wheels, and when the handle retracts again, the wheelsare limited and fixed, and stability is improved.

Description

technical field [0001] The invention relates to the technical field of mobile air conditioners, in particular to a caster wheel control mechanism for mobile air conditioners that is convenient to be concealed. Background technique [0002] The mobile air conditioner is an integral air conditioner. The compressor evaporator and condenser are all integrated together. No installation work is required. The body is equipped with a power plug, which can be used after plugging in the power. There are casters installed below, which can be used as you like. However, the existing casters are only common universal wheels on the market, and the direction of the wheels is not easy to control when moving. Due to the weight of the air conditioner itself, the wheels tend to shift and slip, and it is inconvenient to lock the wheels during transportation. As a result, the air conditioner is easy to shift, and the safety performance is low. Contents of the invention [0003] The purpose of ...
