[CN 201710746348.9] Pipe joint device for hydraulic pipeline of pressure machinery
[CN 201710746348.9] Title of a pipe joint device for hydraulic pipelines of pressure machinery: Application number of a pipe joint device for hydraulic pipelines of pressure machinery: CN 201710746348.9 Applicant: Shanghai Kui Shu Automation Technology Co., Ltd. Application Date: 2017-8-26 Patent Type: Invention Application for a pipe joint device for hydraulic pipelines of pressure machinery, one end of the pipe joint body (2) is screwed on the upper and lower ends of the block (1), the other end of the pipe joint body (2) is connected with the hydraulic pipeline. The left and right ends of the block body (1) are opened with holes, and the piston (5) is sealed and installed in the holes. The tail of the piston (5) passes through the gland (8) and The connecting rod (4) is hinged, the gland (8) is fixed on the block (1), and a spring (7) is installed between the gland (8) and the piston (5), the middle part of the pressing rod (3) is hinged at the end of the block (1), the pressing rod (3) can rotate along the hinge point with the block (1), one end of the pressing rod (3) is hinged with the connecting rod (4), and the other end is pressed against the pipe joint body (2). The pipe joint device can use the hydraulic oil of the pipeline to realize its own locking, and can cooperate with the locking bolt, which improves the working reliability and the response sensitivity to pressure.
