Abstract
The utility model is related to rod piece technical fields, more particularly, to a kind of variable rod piece.Its main feature is that including the multiple duromers contacted by nonelastic rope, one end of nonelastic rope is linked with locking system is tensed, and the other end of nonelastic rope is provided with end.It is by tensing locking system by nonelastic rope stretch, the parallel alien invasion jam-packed of several duromers, duromer with tense locking system joint surface jam-packed, set protrusion and groove are agreed on duromer, after tensing the locking system locking on locking system, straight-bar is formed.Conversely, after locking system is decontroled, gap is generated between the parallel alien invasion of several duromers of the string on nonelastic rope, free bend bar can be formed.It realizes rod piece Qu Yuzhi, soft and hard conversion, simple in structure, is readily produced, operation facility, and use scope is extensive.
Description
Technical field
The utility model is related to rod piece technical fields, more particularly, to a kind of variable rod piece.
Background technology
Existing case drawbar is mostly rigid musical form or straight, there are also rod piece is flexible musical form or straight, and rod piece exists
Qu Yuzhi, it is soft with it is hard between cannot convert, occupation mode is relatively limited, not convenient enough.
Utility model content
The purpose of this utility model is that avoiding the defect of the prior art and providing a kind of variable rod piece, efficiently solve existing
The problem of with the presence of technology.
To achieve the above object, the technical solution that the utility model is taken is：A kind of variable rod piece, its main feature is that
Include the multiple duromers contacted by nonelastic rope, one end of nonelastic rope is linked with locking system is tensed, nonelastic
The other end of rope is provided with end.
The duromer upper surface is provided with protrusion, and the setting of duromer lower face is fluted, is provided among duromer
The hole passed through for nonelastic rope.
Be provided on the tension locking system for across nonelastic rope through hole and for rolling tightly it is nonelastic
The rotating device of rope.
The locking system for the nonelastic rope of folding and unfolding is additionally provided on the tension locking system.
The tip diameter of the nonelastic cable end is more than the hole on duromer.
The utility model has the beneficial effects that：A kind of variable rod piece, may be implemented rod piece Qu Yuzhi, it is soft with it is hard
Conversion, it is simple in structure, be readily produced, operation facility, use scope is extensive.

Locking apparatus；31. through hole；32. rotating device；33. locking system.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figures 1 to 5, a kind of variable rod piece, its main feature is that include contacted by nonelastic rope 2 it is more
A duromer 1, one end of nonelastic rope 2 are linked with locking system 3 is tensed, and the other end of nonelastic rope 2 is provided with end
21。
Further, 1 upper surface of duromer is provided with protrusion 12,1 lower face of duromer setting fluted 13, hard
The hole 11 passed through for nonelastic rope 2 is provided among body 1.
Further, be provided on the tension locking system 3 for across nonelastic rope 2 through hole 31 and be used for
Roll tightly the rotating device 32 of nonelastic rope 2.
Further, the locking system 33 for the nonelastic rope of folding and unfolding 2 is additionally provided on the tension locking system 3.
Further, 21 diameter of end of 2 end of nonelastic rope is more than the hole 11 on duromer 1.
A kind of variable rod piece, in use, being tensed nonelastic rope 2 by tensing locking system 3, multiple hard
The parallel alien invasion jam-packed of body 1, duromer 1 with tense 3 joint surface jam-packed of locking system, set 12 He of protrusion on duromer 1
Groove 13 agrees with, and after tensing 33 locking of locking system on locking system 3, forms straight-bar.Conversely, locking system 33 is put
After opening, gap is generated between the parallel alien invasion of several duromers 1 of the string on nonelastic rope 2, free bend bar can be formed.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
