Title:
PIPELINE CONNECTION STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/211559
Kind Code:
A1
Abstract:
Disclosed is a pipeline connection structure, comprising a main body (1), an inner bushing (2), an outer bushing (3) and a pressure cap (4). When the device is in use, the main body is sleeved on the outside of the inner bushing, and a crack (5) formed between the main body and the inner bushing is used for installing pipes. During installation, the connecting end of a pipe to be installed passes through the pressure cap and the outer bushing in turn from the bottom ends thereof and extends into the crack; the outer bushing is inserted into the crack; the pressure cap is sleeved on the outer bushing and the main body; a first bulge (11) of the main body and the bottom of the pressure cap are clamped by tools such as a caliper and the caliper is pressed tightly such that the pressure cap tightly compresses the outer bushing by interference fitting and the outer bushing is further inserted into the crack, the outer bushing and the inner bushing together compressing the pipe like a compressed sandwich. Both ends of the structure can be connected to a pipe so that two pipes can be connected, which is simple and convenient; and the connection is tight and firm, which can prevent leakage.
