Description

Technical Field

The invention relates to a field of an air conditioner, and in particular to a bearing rubber ring assembly and an air conditioner with the bearing rubber ring assembly.

Background

A bearing rubber ring assembly known to inventors is formed by a bearing rubber ring base and a bearing rubber ring, and two parts are assembled into the bearing rubber ring assembly which is installed on a bottom housing, and has an effect of supporting a cross-flow blade.
Because there is a fastening bolt on a bush (a portion used to connect with a motor) of the cross-flow blade when the cross-flow blade leaves a factory, and it is not completely screwed into a bolt hole, when the cross-flow blade is installed, it needs to pass through an installing hole of the bearing rubber ring assembly, the fastening bolt needs to be unscrewed firstly to prevent the fastening bolt from limiting the cross-flow blade to pass through the installing hole, after the cross-flow blade is installed in position, finally the bolt is screwed into the bolt hole again. Correspondingly, the fastening bolt must be unscrewed when the cross-flow blade is detached.
In view of three steps in assembling and detaching process, waste of action is seriously caused, a production cost is increased, and a production period is prolonged. In addition, when the fastening bolt is screwed into a bolt hole again finally, the fastening bolt is easily slantwise screwed because there is not a guiding structure, a thread damage of the bolt hole of the bush of the cross-flow blade is caused, once the thread damage of the bolt hole of the bush is caused, the cross-flow blade is only carried back to an original factory or directly scrapped, thus the production cost is increased.
