Abstract

The utility model discloses a kind of connecting tube, including:Pipe, the embedded nut that a lateral wall can fit with circular pipe end inwall is respectively embedded into two pipe ends of pipe, the external diameter of embedded nut is more than circular pipe end internal diameter, so that embedded nut is interference fit with circular pipe end, also at least provided with two rotation stop grooves arranged along embedded nut short transverse on the lateral wall of embedded nut, pipe end tube wall at rotation stop groove can cave inward in rotation stop groove because outwards not strutting, so as to which the tube wall being recessed in rotation stop groove can prevent embedded nut from being rotated in circular pipe end;The tube wall of circular pipe pipe port bends inwards so that circular pipe pipe port bore reduces, so as to prevent embedded nut from leaving circular pipe end.A kind of above-mentioned connecting tube need not be welded with regard to that embedded nut can be made to be firmly secured in pipe end, from can substantially reduce cost of labor.

Description

A kind of connecting tube
Technical field
It the utility model is related to connector field, and in particular to a kind of connecting tube.
Background technology
Existing connecting tube would generally be respectively embedded into two pipe ends one be used for connect embedded nut, embedded spiral shell The method of generally use welding is mutually fixed with pipe end after in the embedded pipe end of mother, after embedded nut is fixedly welded in pipe end also Need to polish to the solder joint at pipe end, so the cost of labor of this connecting tube for needing to weld is higher.
Utility model content
Technical problem to be solved in the utility model is:A kind of connecting tube that need not be welded will be provided.
In order to solve the above problems, technical scheme is used by the utility model:A kind of connecting tube, including:Pipe, The embedded nut that a lateral wall can fit with circular pipe end inwall, its feature are respectively embedded into two pipe ends of pipe It is:The external diameter of embedded nut is more than circular pipe end internal diameter so that embedded nut is interference fit with circular pipe end, in insertion Also at least provided with two rotation stop grooves arranged along embedded nut short transverse, rotation stop groove on the lateral wall of formula nut The pipe end tube wall at place can cave inward in rotation stop groove because outwards not strutting, so as to the tube wall energy being recessed in rotation stop groove Prevent embedded nut from being rotated in circular pipe end;The tube wall of circular pipe pipe port bends inwards so that circular pipe pipe port bore contracts It is small, so as to prevent embedded nut from leaving circular pipe end.
Further, foregoing a kind of connecting tube, wherein:The external diameter of embedded nut is bigger than the internal diameter of circular pipe end by 0.1 ~0.3mm.
Further, foregoing a kind of connecting tube, wherein:Three rotation stops are evenly arranged with the lateral wall of embedded nut Groove.
The advantages of the utility model is:A kind of connecting tube described in the utility model need not be welded with regard to that can make embedded spiral shell Mother is firmly secured in pipe end, from can substantially reduce cost of labor.
Brief description of the drawings
Fig. 1 is a kind of structural representation of connecting tube described in the utility model.
Embodiment
The utility model is described in further detail with reference to specific embodiments and the drawings.
As shown in figure 1, a kind of connecting tube, including:Pipe 1, a lateral wall is respectively embedded into two pipe ends of pipe 1 The embedded nut 2 that can be fitted with the pipe end inwall of pipe 1, the external diameter of embedded nut 2 are more than the pipe end internal diameter of pipe 1, at this In embodiment, the external diameter of embedded nut 2 is bigger 0.1~0.3mm than the internal diameter of the pipe end of pipe 1 so that embedded nut 2 and pipe 1 pipe end is interference fit, and three are also evenly arranged with the lateral wall of embedded nut 2 along the height side of embedded nut 2 To the rotation stop groove 3 of arrangement, the pipe end tube wall at rotation stop groove 3 can be caved inward because outwards not strutting in rotation stop groove 3 In, so as to which the tube wall being recessed in rotation stop groove 3 can prevent embedded nut 2 from being rotated in the pipe end of pipe 1;The pipe port of pipe 1 Tube wall bends inwards so that the pipe port bore of pipe 1 reduces, so as to prevent embedded nut 2 from leaving the pipe end of pipe 1.

Claims (3)

1. a kind of connecting tube, including:Pipe, be respectively embedded into two pipe ends of pipe a lateral wall can with circular pipe end The embedded nut that wall fits, it is characterised in that:The external diameter of embedded nut is more than circular pipe end internal diameter so that embedded spiral shell Female with circular pipe end is interference fit, also at least provided with two along embedded nut height on the lateral wall of embedded nut The rotation stop groove of direction arrangement is spent, the pipe end tube wall at rotation stop groove can be caved inward because outwards not strutting in rotation stop groove In, so as to which the tube wall being recessed in rotation stop groove can prevent embedded nut from being rotated in circular pipe end;The tube wall of circular pipe pipe port Bend inwards so that circular pipe pipe port bore reduces, so as to prevent embedded nut from leaving circular pipe end.
A kind of 2. connecting tube according to claim 1, it is characterised in that:The external diameter of embedded nut is than in circular pipe end Big 0.1~the 0.3mm in footpath.
A kind of 3. connecting tube according to claim 1 or 2, it is characterised in that:Uniformly set on the lateral wall of embedded nut It is equipped with three rotation stop grooves.
