Abstract
Provided is an expansion locking type pipe joint for connecting a soft pipe and a hard pipe. The expansion locking type pipe joint is composed of a nut (1) and an expansion sleeve (2), and is characterized in that the nut (1) is arranged on the expansion sleeve (2), the expansion sleeve (2) is arranged on the end portion of the soft pipe (3), the soft pipe (3) is sleeved on the hard pipe (4), the expansion sleeve (2) shrinks through screwing of the nut (1), consequently the soft pipe (3) can be pressed on an arc-shaped annular groove (12) of the hard pipe (4), and therefore stable connection of the soft pipe (3) and the hard pipe (4) can be achieved. The expansion locking type pipe joint can be used for connection of pipelines which need frequently disassemblies and have certain requirements on sealing and has the advantages of being easy to manufacture, convenient to disassemble and reliable and stable in use.
Description
Technical field
The pipeline that the utility model relates to Fluid Transport connects, particularly the expansion locking type pipe joint of a kind of connecting hose and hard tube.
Background technique:In industries such as a lot of engineering machinery, machine tools, the media such as oil and water are the essential conditions that machine runs well, and will run into the problem that pipeline connects in the oily transmitting procedure that is connected with water.Pipe joint plays a part to cause the pass important as the bridge that two pipes connect.At present, the pipe joint of extensive use is of a great variety, does not also find a kind of not only reliable sealing but also dismantles pipe joint easily but be connected the aspect with hard tube for flexible pipe.Therefore, the pipe joint that is connected with hard tube in the urgent need to inventing a kind of flexible pipe, being beneficial to has again the occasion of seal request to improve its working efficiency in frequent dismounting, increases reliability.
Summary of the invention:The purpose of this utility model is that the Fluid Transport occasion to flexible pipe connection hard tube provides a kind of pipe joint of high efficient and reliable, and this pipe joint can be realized quick-detachment and the connection of being connected.
Formation of the present utility model: the expansion locking type pipe joint of a kind of connecting hose and hard tube, formed by nut and expansion sleeve, it is characterized in that: nut is installed on expansion sleeve, expansion sleeve is contained in hose end, hose proof is on hard tube, by fastening nut, expansion sleeve being shunk makes flexible pipe be pressed on the circular arc-shaped ring groove of hard tube, realizes that flexible pipe is connected with the firm of hard tube.
The nut profile is six rib square toes A structures, and endoporus is internal thread, the excessive part of end face of nut and endoporus be one wealthy mouthful with the excessive circular arc of circular arc.
Expansion sleeve one end is six rib square toes B, several openings of the other end band, and each open interior is semicircular transition arc projection by end sections.
Hard tube has circular arc-shaped ring groove in the part of being combined with flexible pipe.
Compared with prior art, the utlity model has following features: can realize not only dismantling convenient but also reliable and stable connection, simple in structure, easy to operate, especially in the oil circuit that engineering machinery is connected with machine industry connects, greatly improve its working efficiency and reliability.
