Abstract
The invention provides a hose coupler, which comprises a connection, a hose body, a connecting nut and a rubber pad, wherein an annular groove is arranged in the outer surface of the connection, the connection is fixedly connected to the hose body, external threads are arranged at the back of the hose body, the connecting nut matched with the hose body is arranged at the back of the hose body, the rubber pad is arranged between the connecting nut and the back of the hose body; the middle of the hose body is sleeved with a nut; an annular baffle is arranged on the back end face of the connecting nut. The hose coupler has the beneficial effects of firm connection, good sealing property and safety use.
Description
Technical field
The invention belongs to link field, especially relate to a kind of hose coupling.
Background technique
Use the equipment of gas or liquid-working-medium, the conveyance conduit of medium adopts flexible pipe, it is a kind of commonplace phenomenon that the connection of all kinds of high and low pressure flexible pipes is used, especially take oxygen, combustion gas, pressurized air and nitrogen, hydrogen, argon, carbon dioxide etc. as the hot working unit of working medium all the more so.The connection of flexible pipe, mode generally all adopts iron wire binding or pipe collar (comprise and be squeezed into pattern pipe collar and screw tension-type pipe collar) to be connected, the common feature of these three kinds of Placements is to make the flexible pipe of tied or banding produce internal withdraw type extrusion-deformation, internal surface or inner tube internal surface by flexible pipe, realize sealing and be connected with the anti-slip frictional resistance being connected between tube core (with inverted cone surface pipe joint or the smooth straight joint of CONCENTRIC REDUCER diameter) outer surface, its connection power only results from pipe internal surface.This simple Placement is insecure, and the phenomenon that easily occurs coming off and leak, can not be used for a long time.
Summary of the invention
The object of this invention is to provide a kind of hose coupling, be connected firmly, facilitate, safe.
Technological scheme of the present invention is: a kind of hose coupling, comprise connection nipple, pipe shaft, attaching nut and rubber pad, connection nipple outer surface is provided with annular groove, connection nipple is fixedly connected with pipe shaft, pipe shaft rear portion is provided with outside thread, pipe shaft rear portion is provided with an attaching nut who is used in conjunction with pipe shaft, between attaching nut and pipe shaft rear portion, is provided with rubber pad.
Described pipe shaft middle part is arranged with nut, and this nut and pipe shaft are fixed.
The end edge of described connection nipple is arc.
Described attaching nut's ear end face is provided with ring baffle.
Advantage and good effect that the present invention has are: the annular groove on connection nipple can play anti-skidding effect, and nut and the pipe shaft at pipe shaft middle part are fixed, and can, conveniently with spanner dismounting, make to dismantle more convenient; Pipe shaft rear portion is connected by outside thread with attaching nut, makes to connect more convenient; Meanwhile, between attaching nut and pipe shaft, rubber pad is set, has guaranteed sealing; The ring baffle that attaching nut rear end arranges, can place rubber pad and come off, and rubber pad is played the effect of extruding, enhanced leaktightness simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, the present invention is a kind of hose coupling, comprise connection nipple 1, pipe shaft 2, attaching nut 3 and rubber pad 4, connection nipple 1 outer surface is provided with annular groove 5, connection nipple 1 is fixedly connected with pipe shaft 2, pipe shaft 2 rear portions are provided with outside thread, and pipe shaft 2 rear portions are provided with an attaching nut 3 who is used in conjunction with pipe shaft 2, between attaching nut 3 and pipe shaft 2 rear portions, are provided with rubber pad 4.
Described pipe shaft 2 middle parts are arranged with nut 6, and this nut 6 is fixing with pipe shaft 2.
The end edge of described connection nipple 1 is arc.
Described attaching nut's 3 ear end face is provided with ring baffle 7.
The advantage of tool of the present invention is: the annular groove 5 on connection nipple 1 can play anti-skidding effect, and the nut 6 at pipe shaft 2 middle parts is fixing with pipe shaft 2, can, conveniently with spanner dismounting, make to dismantle more convenient; Pipe shaft 2 rear portions are connected by outside thread with attaching nut 3, make to connect more convenient; Meanwhile, 2 of attaching nut 3 and pipe shafts arrange rubber pad 4, have guaranteed sealing; The ring baffle 7 that attaching nut 3 rear ends arrange, can place rubber pad 4 and come off, and rubber pad 4 is played the effect of extruding, enhanced leaktightness simultaneously.The end edge of connection nipple 1 is arc, can prevent liquid wall built-up.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
