Description

 Screw cap assembly and air conditioner

Technical field

The invention relates to the technical field of air conditioners, and in particular to a screw cap assembly and an air conditioner.

Background technique

With the development of the market, the market demand for indoor air conditioner indoor units is getting higher and higher to meet the aesthetic needs of consumers. Due to the large number of indoor unit structures, the connection of the air-conditioning indoor machine frame frame generally needs to be fixed by screws. In order to prevent the screw head from exposing the surface of the product and affecting the appearance and scratching of people or other parts, it is usually necessary to make a counterbore structure at the position of the screw so that the head of the screw is hidden in the counterbore. However, if the structure is directly exposed, it will affect the appearance of the product; because it is located at the air outlet of the air conditioner, it will also affect the performance of the product; and the screw is exposed to the air, which is prone to rust and deposits dust for a long time.

At present, the air conditioner generally adds a screw cover at the sinking table, and the above defects are solved by hiding the screws. The matching between the screw cover of the existing air conditioner indoor unit and the face frame is based on the rotating shaft on the left and right sides of the lower end of the screw cover as a fulcrum, and a small square table is arranged on both sides of the screw cover, and the small square table forms an interference fit with the mounting groove on the face frame. , so that the screw cap is forcibly caught on the mounting groove.
