Each locking plate of described ring lock, the one end links to each other with first joint, and the other end has inside latch, and the latch on described these locking plates surrounds an annular, and internal diameter that should annular equals or be slightly larger than the external diameter of flexible pipe.
The internal thread of described installation head and the outside thread of first, second joint are trapezoidal thread, and described installation head screws mutually with the outside thread of hose coupling by the internal thread and first joint.When the installation head was connected by screw-thread fit with hose coupling, the slope that the head upper end is installed was stuck in the outside of hose coupling ring lock, and it is applied an inside pressure.
The lower end of described hose coupling is provided with projection, and a described installation lower end offers groove, the protruding corresponding setting on this groove and the hose coupling, and during installation, projection embeds in the corresponding groove.
The lower end of described second joint also offers annular groove, is used to place seal ring.
Described installation head upper end is a circular crosssection, and the lower end is that a periphery is regular hexagon, interior week to be circular cross section.
Described ring lock, first joint, flexible pipe limited part and second joint are integrally formed manufacturings.
The cross-sectional profile of the flexible pipe limited part of described hose coupling is a regular hexagon.
The hose coupling device that the utility model provides owing to adopt screw thread to screw and the design of ring lock clamping type, so easy installation and removal is compatible good, is applicable to the flexible pipe of any kind.
Description of drawings
Fig. 1 is the structural representation of the utility model hose coupling device.
Embodiment
Following according to Fig. 1, specify better embodiment of the present utility model:
As shown in Figure 1, the utility model provides a kind of hose coupling device, and the tubulose that comprises supporting setting installs 1 and tubular hose joint 2, and flexible pipe promptly is to penetrate from 1 upper end is installed, and is installed in the hose coupling 2.
The upper end of described installation 1 is a circular crosssection, and the inboard of upper end portion has a slope 11, and promptly from the top, its internal radius increases gradually.The lower end that head is installed is that a periphery is regular hexagon, interior week to be circular cross section, and the madial wall of underpart is provided with trapezoidal internal thread 12.Also has an internal surface that seamlessly transits between the top of the bottom of this slope 11 and internal thread 12.
Described hose coupling 2 comprises ring lock 21, first joint 22, flexible pipe limited part 23 and second joint 24 from top to bottom successively, and above-mentioned parts can be integrally formed manufacturings.
The inboard of ring lock 21 and first joint, 22 seam crossings is provided with first step 25, and the inboard of first joint 22 and flexible pipe limited part 23 seam crossings is provided with second step 26, the internal diameter of first step 25 is greater than the external diameter of flexible pipe, so that flexible pipe passes, the internal diameter of second step 26 is used for flexible pipe spacing less than the external diameter of flexible pipe.
For fixed installation 1 and hose coupling 2 better, can offer breach installing on 1 the following end section, and projection is set in the corresponding position of hose coupling 2 first joints 22 lower ends, like this, when installing 1 when screwing on earth with hose coupling 2, projection embeds in the breach, can prevent to shake to circle round, and further plays fixation.
In addition, second joint, 24 lower ends also can be provided with annular groove 27, are used to place seal ring so that better protection to be provided.
During installation flexible pipe worn into installation 1, insert hose coupling 2 then, tighten and install 1, a 1 interior slope 11 is installed is aimed at the ring lock 21 of hose couplings 2 lower ends, and locking ring lock 21, this moment ring lock 21 grip both hose, this ring lock 21 has superpower tension and anti-side pulling.To install 1 during dismounting to counterrotating, ring lock 2 is unclamped, just flexible pipe can be extracted from hose coupling 2 like a cork together with installing 1.
