Description

Technical Field

[0001] The utility model relates to the technical field of connection component equipment, in particular to a connection component for a stainless steel ventilation pipe. Background Art

[0002] Ventilation ducts are hollow pipes used for ventilation and can be categorized by application into: purification system return air ducts, industrial supply and exhaust ducts, fire smoke ducts, and more. Existing ventilation ducts require two ducts to be connected during installation. This connection typically requires specialized personnel using specialized tools. This requires high technical expertise, is inconvenient, and reduces connection efficiency. Therefore, we propose a stainless steel ventilation duct connection assembly.

[0003] The application number is CN202122930038.7, which discloses a connection assembly for a stainless steel ventilation pipe. When installing the existing ventilation pipe, it is necessary to connect the two ventilation pipes. The connection of the ventilation pipes usually requires professional connection personnel to connect the two ventilation pipes using professional tools. It is highly professional, but the connection is inconvenient, which reduces the connection efficiency. The following solution is proposed, which includes a first ventilation pipe and a second ventilation pipe, and the top and bottom of the first ventilation pipe are fixedly connected to a connection box, the top and bottom of the second ventilation pipe are fixedly connected to a fixing plate, and the left sides of the two fixing plates are fixedly connected to a connecting plate. The utility model has a reasonable structure and is easy to operate. The power assembly can make the card block and the card slot engage, so that the first ventilation pipe and the second ventilation pipe can be connected. No professional tools are required, the operation is convenient, the connection speed is fast, and the connection efficiency is improved.

[0004] The connection assembly of a stainless steel ventilation pipe disclosed in the above document has the following defects: when the pipe is not needed for ventilation, the pipe mouth needs to be sealed to prevent dust from entering and accumulating in the pipe. The airflow carrying a large amount of dust flowing out through the pipe will cause adverse harm to the human body and affect the subsequent ventilation work of the pipe.

[0005] It can be seen from this that the existing connection components of the stainless steel ventilation pipe do not have the function of protecting the pipe port from dust. It is necessary to improve the existing deficiencies and provide a function that can protect the pipe port from dust. Utility Model Content
