Document Type and Number:
WIPO Patent Application WO/2021/103405
Kind Code:
A1
Abstract:
Disclosed is a dismounting prevention pipe connector, comprising a pipe-connecting nut (100) and a pipe-connecting bolt (200). The pipe-connecting bolt (200) comprises a connecting portion (210) and a mounting and dismounting portion (220), the pipe-connecting nut (100) is sleeved on the outer surface of the connecting portion (210) and is fixedly connected to the connecting portion (210), the outer surfaces of the pipe-connecting nut (100) and the mounting and dismounting portion (220) are smooth curved surfaces, a mounting and dismounting member (300) is arranged on the outer surface of at least one of the pipe-connecting nut (100) and the mounting and dismounting portion (220), and the mounting and dismounting member (300) can be connected to a matched mounting and dismounting tool to achieve mounting and dismounting of the pipe connector. Further disclosed are a dismounting prevention pipe connector assembly and an air conditioner which comprise the dismounting prevention pipe connector. Due to the fact that the outer surfaces of the pipe-connecting nut (100) and the mounting and dismounting portion (220) are smooth curved surfaces, a force cannot be applied by using a wrench in the prior art, and the dismounting prevention purpose is thus achieved; and the mounting and dismounting member (300) is arranged on the outer surface of at least one of the pipe-connecting nut (100) and the mounting and dismounting portion (220), and the mounting and dismounting member (300) can be connected to the matched mounting and dismounting tool to achieve mounting and dismounting of the pipe connector, such that requirements for normal mounting and daily repair and maintenance of the pipe connector can be met.
