Description

Technical Field

[0001] The utility model relates to the technical field of metal hoses, in particular to a connecting metal hose for a pump. Background Art

[0002] With the development of industry, pump applications are becoming increasingly diverse, and the requirements for their connecting pipes are also increasing. In high-precision production processes, such as semiconductor manufacturing, pumps must not only stably deliver media such as chemical reagents, but also connect pipes that minimize vibration transmission. Even small vibrations can affect the precision of semiconductor manufacturing equipment, resulting in reduced product quality.

[0003] The Chinese patent publication number is CN219140141U, a metal hose for connecting pumps. The technical solution provided by the patent document is as follows: it includes a metal hose body, a connector and a bolt, the connector is provided with a threaded hole, the internal thread of the threaded hole is connected to the bolt, one end of the metal hose body is fixedly connected to the connector, the interior of the connector is provided with a docking hole, the docking hole and the connector are interconnected, a leather ring is provided inside the docking hole, and the leather ring is fixedly connected to one end of the metal hose body; it also includes a fixing component, the fixing component is used for the connector to perform docking work. The utility model has a reasonable structure, and realizes that the metal hose body can be quickly docked with the joint through the fixing component inside the connector, and then the connector can be prevented from falling off during use by the bolt. The docking process is very fast and will not delay the progress of the work.

[0004] In order to solve the problem that when the existing metal hose is connected to the water pump, most of them use nuts to connect the metal hose to the water pump. The existing technology uses a limit rod to fit on the docking head through the elastic force of a spring until one end of the joint is tightly fitted with the leather ring. However, the installation is more complicated and the connection is more unstable, which leads to a decrease in stability. Utility Model Content
