Description

Technical Field

[0001] The utility model relates to the field of micro-pipeline connection, in particular to a novel nitrogen spring pipeline joint. Background Art

[0002] Currently, there are three main types of nitrogen spring connection systems, namely, micro-pipe connection system (M8 x 1); EZ hose system (S12.65 x 1.5); EO24 hose system (M12 x 1.5); the most commonly used is the first type: each connector is directly inserted into the nitrogen spring cylinder, and then each connector is connected to the air pipe to form an integrated pipe connection system; the principles of other systems are the same, but the existing connection method is unreasonable, consisting of a structural perforated screw + combined gasket + multi-directional joint, in which the combined gasket is prone to deformation, resulting in leakage and failure. The existing plug-in joint is fixed on the nitrogen spring cylinder by tightening the screws. The principle is that the internal hole of the screw is connected to the joint, and then connected to the air pipe to realize the connection between multiple nitrogen springs.

[0003] The disadvantages of this connection method are very obvious. The combined gasket is easily deformed by extrusion and is used too much. The sealing performance of the combined gasket is poor, which often leads to failure of the entire sealing system. In addition, this sealing method does not have the function of rotation. Once the screws are tightened, it will leak and fail once rotated. It is easy to be damaged during installation and adjustment, and multiple combined gaskets must be replaced, resulting in loss and waste of time and material resources.

[0004] Therefore, it is necessary to provide a new type of nitrogen spring pipeline connector to solve the above technical problems. Utility Model Content
