Connecting pipe plug and air conditioner

Abstract

The invention discloses a connecting pipe plug and an air conditioner, and belongs to the technical field of air conditioners and accessories thereof. The connecting pipe plug is designed to solve the problems that an existing connecting pipe plug is poor in sealing performance and low in operation efficiency. The connecting pipe plug comprises a hollow plug body with openings in the two ends and a plug cover. The plug body is used for being arranged at the end of a connecting pipe in a sealing and sleeving manner, and the plug cover is used for plugging the end, far away from the connecting pipe, of the plug body. The connecting pipe plug is good in sealing performance, convenient to operate and high in operation efficiency. Due to the adoption of the connecting pipe plug, the air conditioner is good in connecting pipe sealing performance and longer in service life.

Description

technical field [0001] The invention relates to the technical field of air conditioners and accessories thereof, in particular to a connecting pipe plug and an air conditioner using the connecting pipe plug. Background technique [0002] Split-type air conditioners generally connect the indoor unit and outdoor unit through connecting pipes, such as figure 1 As shown, the air conditioner connecting pipe 4 includes a pipe body and a nut sleeved on one end of the pipe body. The nut includes a hex nut body 41 and a frustum-shaped connection port 42 connected to one end of the hex nut body 41 . Before after-sales installation, in order to prevent the connecting pipe from being dirty during production and transportation, a common method is to use a plug to seal and protect the nut and the pipe body of the connecting pipe. [0003] Such as Figure 2 to Figure 4 As shown, the current industry generally has plugs such as screw-in type and push-type plugs, among which the push-type ...

AI Technical Summary

Problems solved by technology

Among them, the screw-in plug needs to be screwed in gradually along the internal thread of the nut, and the sealing performance is better, but the operation efficiency is low, and it has been phased out; the one-piece push plug can be directly pressed into the nut of the connecting pipe, and the operation High efficiency, but there is a gap after assembly, and the sealing performance is low; the combined pressing plug usually includes a separate barrel-shaped hollow expansion tube and an expansion plug used in conjunction with the expansion tube, and the expansion plug is inserted into the hollow cavity of the expansion tube Among them, the outer wall of the expansion tube is matched with the inner wall of the nut of the connecting tube to achieve sealing, and the sealing performance is better, but since multiple separate parts are required, the operation is troublesome, and the cost is higher than that of the one-piece pressing plug
