Jack catch formula natural gas connects locking device

The utility model provides a jack catch formula natural gas connects locking device belongs to natural gas transportation technical field, including jack catch fixing base, jack catch and supporting jack catch actuating mechanism, the key lies in: the two connecting rod structures of complex that the jack catch was formed by rotation connecting rod and translation connecting rod hinge together, it articulates on the jack catch fixing base to rotate the connecting rod, the free end and the jack catch actuating mechanism of translation connecting rod are connected. The beneficial effects of the utility model are that: (1 )The jack catch articulates on the jack catch fixing base, through supporting jack catch actuating mechanism, connects two and locks fast, and the locking effect is reliable and stable, (2 )The two connecting rod structures of complex that the jack catch was formed by rotation connecting rod and translation connecting rod hinge together, simple structure, meeting auto -lock when lock status, (3 )Its endwise slip can be followed through cylinder, promotion seat, actuating lever drive slip loop at the disk seat surface, the purpose of a cylinder drive multiunit jack catch has been reached.
