Description

The detecting tool of cable minimum bending radius
Technical field
The present invention relates to a kind of detecting tools of cable minimum bending radius.
Background technology
When the production of cable is with being electrically connected, the fixation of the minimum bend radius of curvature of cable, when the bending of cable is more than During the radius of curvature of setting, the service life of cable and the quality of product can be seriously affected to the irreversible damage of cable output.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of detecting tool of cable minimum bending radius.
To solve the above problems, the technical solution used in the present invention is:
The present invention it include the first arc pipe, with first arc pipe one end connecting tube being connected and be connected with connecting tube one end second Arc pipe, the first arc pipe include the first intrados corresponding with the external arc of bending cable and corresponding with the Inner arc of bending cable The first extrados,
First arc pipe is identical with the second arc pipe structure, and the outer diameter of connecting tube is not more than the outer diameter of the first arc pipe;
Transition arc sleeve is movably installed on the first arc pipe, the endoporus of transition arc sleeve and the outer circle gap of the first arc pipe are matched somebody with somebody It closes;
Transition arc sleeve includes transition intrados corresponding with the external arc of bending cable and the Inner arc pair with bending cable The transition extrados answered.
As a further improvement on the present invention, the first arc pipe and connecting tube plug connection, the second arc pipe and connecting tube grafting Connection.
It is using advantageous effect caused by above-mentioned technical proposal:
The present invention sets the crooked radian of the first arc pipe and the second arc pipe according to the common Cable Bending Radius of enterprise, thus the One intrados is corresponding with the external arc bending radius of respective cable, the Inner arc bending radius pair of the first extrados and respective cable Should, so as to increase its versatility, the transition arc sleeve of corresponding bending radius is made further according to the cable of corresponding different tube diameters, So as to increase its versatility, saving cost of manufacture is convenient and practical, easy to spread.During using the present invention, according to electric after assembling product The actual conditions of cable check the Inner arc bending radius of its cable with transition extrados or the first extrados, can also pass through It crosses intrados or the first intrados checks the external arc bending radius of its cable, convenient and practical, using flexible detects directly perceived accurate Really;By plug connection, it can also realize the 360 ° of rotations of the first arc pipe or the second arc pipe relative to connecting tube, further increase and survey The convenience of amount and flexibility.The present invention is of low cost, is suitble to large-scale promotion.

Specific embodiment
As shown in Figs. 1-3, the present invention it include the first arc pipe 1, the connecting tube 2 being connected with 1 one end of the first arc pipe and with 2 one end of connecting tube connection the second arc pipe 3, the first arc pipe 1 include the first intrados 8 corresponding with the external arc of bending cable with And the first extrados 9 corresponding with the Inner arc of bending cable,
First arc pipe 1 is identical with 3 structure of the second arc pipe, and the outer diameter of connecting tube 2 is not more than the outer diameter of the first arc pipe 1;
Transition arc sleeve 4 is movably installed on the first arc pipe 1, between the outer circle of the 5 and first arc pipe 1 of endoporus of transition arc sleeve 4 Gap coordinates;
Transition arc sleeve 4 includes transition intrados 6 corresponding with the external arc of bending cable and the Inner arc with bending cable Corresponding transition extrados 7.
Further, the first arc pipe 1 and 2 plug connection of connecting tube, the second arc pipe 3 and 2 plug connection of connecting tube.
The crooked radian of first arc pipe 1 and the second arc pipe 3 is set according to the common Cable Bending Radius of enterprise, thus the One intrados 8 is corresponding with the external arc bending radius of respective cable, the first extrados 9 and the Inner arc bending radius of respective cable It is corresponding, so as to increase its versatility, the transition arc of corresponding bending radius is made further according to the cable of corresponding different tube diameters Set 4 so as to increase its versatility, saves cost of manufacture, convenient and practical, easy to spread.During using the present invention, according to assembling product The actual conditions of cable afterwards check the Inner arc bending radius of its cable with 7 or first extrados 9 of transition extrados, can also The external arc bending radius of its cable, convenient and practical, using flexible, detection are checked by 6 or first intrados 8 of transition intrados It is directly perceived accurate.
By plug connection, the 360 ° of rotations of the first arc pipe 1 or the second arc pipe 3 relative to connecting tube 2 can also be realized, into one Step increases convenience and the flexibility of measurement.The present invention is of low cost, is suitble to large-scale promotion.
Finally it should be noted that:The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations;Although The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that:It still may be used To modify to the technical solution recorded in previous embodiment or carry out equivalent substitution to which part technical characteristic;Make It is obvious that multiple technical solutions of the present invention, which are combined, for those skilled in the art.And these are changed or replace It changes, the essence of appropriate technical solution is not made to depart from the spirit and scope of technical solution of the embodiment of the present invention.
