Abstract

The invention provides a sealing plug structure which comprises an expansion plug and an expansion sleeve. The expansion plug is inserted in the expansion sleeve, and the outer surface of the expansion plug is matched with the inner surface of the expansion sleeve to expand the expansion sleeve. Through the expansion principle, the expansion plug is pressed in the expansion sleeve to expand the expansion sleeve, so that the expansion sleeve can be connected with a matched body, and the sealing effect is achieved. Moreover, the operation process is simple, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a sealing plug structure. Background technique [0002] In the prior art, the threaded plastic plug and the corresponding copper nut are screwed together to achieve the purpose of not falling off. The production efficiency of this mode is low, and manual operation is difficult. Contents of the invention [0003] The purpose of the present invention is to provide a sealing plug structure to solve the technical problems of difficult manual operation and low production efficiency. [0004] To achieve the above object, the present invention provides a sealing plug structure, including an expansion plug; an expansion sleeve, the expansion plug is inserted into the expansion sleeve, and the expansion sleeve is expanded by the cooperation between the outer surface of the expansion plug and the inner surface of the expansion sleeve. [0005] Further, the inner end of the expansion sle...
