Description
Technical field
The utility model relates to a kind of liner copper pipe, particularly relates to a kind of umbrella handle liner copper pipe with grid projection.
Background technology
Folded umbrella is comparatively common daily necessities, the umbrella handle of folded umbrella is usually by being mutually inserted in the tubular structure that also pull is flexible, when the outer handle pipe of stainless steel is inserted in interior handle pipe, outer handle inside pipe wall and interior handle pipe outer wall produce rub larger, and abnormal ear-piercing sound can be produced when the outer handle pipe of the stainless steel that hardness is larger and the friction of interior handle pipe mutual pull, in draw process, the pause and transition in rhythm or melody sense of frictional force is poor, and when pulling dynamic, feel is poor, and the long-time umbrella handle that uses easily damages due to friction.Usually the good copper pipe of frictional behaviour is set between interior handle pipe and outer handle tube wall in prior art, because copper pipe price is higher, usually a bit of copper pipe is only used to be fixed on outer handle inside pipe wall, frictional behaviour between interior handle pipe and copper pipe inwall can because copper material ductility be better, rub comparatively soft, and then eliminate noise.But still to have occurred in prior art between copper pipe and interior handle pipe that frictional force is comparatively large, more difficultly copper pipe to be fixed on outer handle inside pipe wall, and the generation of copper pipe upper rail shape and the matching problem with umbrella handle shape of cross section.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, provides a kind of umbrella handle liner copper pipe with grid projection that can reduce frictional force between interior handle pipe and copper pipe.
For achieving the above object, the technical solution adopted in the utility model is: a kind of umbrella handle liner copper pipe with grid projection, described umbrella handle is provided with that be set-located can the flexible interior handle pipe of pull and outer handle pipe, described copper pipe is fixedly installed on handle inside pipe wall outside near one end that described interior handle pipe is inserted in, described interior handle pipe outer wall can relative sliding be inserted in described copper pipe, it is characterized in that, cross section is that circular described copper pipe is circumferentially with one section of arc guide barrel inwardly concaved, copper pipe axis being parallel described in described guide groove bearing of trend, the described guide groove that described copper pipe is provided with and described interior handle pipe and described outer handle pipe shape of cross section coincide, described copper pipe inwall is provided with some the described projections consistent with its axis direction.
In the utility model preferred embodiment, some described bulge clearances are arranged on uniformly except being provided with on the described copper pipe inwall of described guide barrel construction.
In the utility model preferred embodiment, the cross section of described projection is trapezoidal, and described trapezoidal going to the bottom is arranged on described copper pipe inwall, and described trapezoidal upper base is straight line or the camber line to described copper pipe lateral direction projection.
In the utility model preferred embodiment, described copper pipe sidewall is provided with the bullet hole clipping running through inside and outside, the bullet hole clipping position consistency that described bullet hole clipping and described outer handle pipe are provided with through.
In the utility model preferred embodiment, the described bullet hole clipping on described copper pipe is oval, and described oval major axis is consistent with described copper pipe axis direction.
In the utility model preferred embodiment, the stickup that described copper pipe outer wall and described outer handle inside pipe wall shape are coincide fixes or buckle is fixed together, and described interior handle pipe outer wall can contact with inner side protruding described in several simultaneously in axial sliding.
The utility model solves the defect existed in background technology, the utility model is provided with strip bulge circumferentially at copper pipe inwall, can frictional force effectively between less copper pipe inwall and interior handle pipe outer wall, utilize simultaneously the ductility of copper can good less pull stretch interior handle pipe and outer handle pipe time the grating noise that produces, and it is soft effectively to achieve stablizing of frictional force in draw process, less pull pause and transition in rhythm or melody sense.

Detailed description of the invention
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-5, a kind of umbrella handle liner copper pipe 3 with grid projection 6, umbrella handle is provided with that be set-located can the flexible interior handle pipe 1 of pull and outer handle pipe 2, copper pipe 3 is fixedly installed on handle pipe 2 inwall outside near one end that interior handle pipe 1 is inserted in, interior handle pipe 1 outer wall can relative sliding be inserted in copper pipe 3, cross section is that circular copper pipe 3 is circumferentially with one section of arc guide barrel inwardly concaved 4, guide groove 4 bearing of trend copper pipe 3 axis being parallel, the guide groove 4 that copper pipe 3 is provided with coincide with interior handle pipe 1 and outer handle pipe 2 shape of cross section, the setting of guide groove 4 can ensure interior handle pipe 1, relative rotation can not be there is in circumference when outer handle pipe 2 is set-located with copper pipe 3 three, spring clip device is made to can be good at entering or leaving playing hole clipping 5, handle pipe 1 and the mutual locking of outer handle pipe 2 in ensureing.
Copper pipe 3 inwall is provided with the projection 6 consistent with its axis direction.Some projection 6 interval is arranged on except being provided with on copper pipe 3 inwall of guide groove 4 structure uniformly, and the cross section of protruding 6 is trapezoidal, and trapezoidal going to the bottom is arranged on copper pipe 3 inwall, and trapezoidal upper base is straight line 8 or the camber line 7 to copper pipe 3 lateral direction projection 6.The setting of protruding 6 can make the friction area between interior handle pipe 1 outer wall and copper pipe 3 inwall greatly reduce, and the preferred new biography of protruding 6 of the utility model is trapezoidal, and its upper base preferred embodiment one is arc, can better agree with interior handle pipe 1 outer wall surface like this.The upper base of preferred embodiment two is straight line 8.
Copper pipe 3 sidewall is provided with the bullet hole clipping 5 running through inside and outside, and play the through of bullet hole clipping 5 position consistency that hole clipping 5 is provided with outer handle pipe 2, the bullet hole clipping 5 on copper pipe 3 be ellipse, and oval major axis is consistent with copper pipe 3 axis direction.The bullet hole clipping 5 that oval bullet hole clipping 5 can make spring clip device comparatively be easy to enter or leave outer handle pipe 2 to be provided with preferably.
The stickup that copper pipe 3 outer wall and outer handle pipe 2 inner wall shape are coincide fixes or buckle is fixed together, such copper pipe 3 can not slide in handle pipe 2 arbitrarily outside, and ensure that the bullet hole clipping 5 that copper pipe 3 and outer handle pipe 2 are respectively equipped with can inside and outsidely be mated, can not mutual dislocation, interior handle pipe 1 outer wall can contact simultaneously with inside several projections 6 in axial sliding, the ductility of copper pipe 3 can make friction between the two softer, can not send abnormal sound.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to right.
