Description
The utility model is the interconnecting of pipe in relevant a kind of link, refers to that especially a kind of fixed block of borrowing bestows the uniform clamping force of locating piece, and the relative position of pipe and outer tube is clamped and the multipurpose flexible rod of locating in making.
Shown in Fig. 5,6, be existing first kind of flexible rod 7, it comprises a bassoon 71 and a tubule 72, and tubule 72 is axially to be sheathed in the bassoon 71, bassoon 71, tubule 72 jointing places are provided with a pipe box 73, a head part 74, and the former all is provided with involutory 76, and tubule 72 sheathed end caps 75, be provided with an eccentric lever 77 in pipe box 73 1 sides, borrow rotate eccentric lever 77 and withstand this tubule 72 and locate.
Shown in Fig. 7,8, be existing second kind of flexible rod, be in bassoon 71, to wear porosely 8, pass and packing tubule 72 with a bolt 81, make bassoon 71 and tubule 72 location, and the end of bassoon 71 is provided with end cap 82.
Yet above-mentioned two kinds of flexible rods all need just can use flexible rod 7 processing, the end of member also need sheathed end cap 75,82 to avoid hurting the user, reach in the making all quite trouble in the use, and locating effect is also bad.Because the suffered packing strength of these two kinds of flexible rods all concentrates on a place, the former concentrates on head part 74, the latter concentrates on tubule 72 and bolt 81 contact positions, be not easy to control the size of packing strength, produce too loose and effect that can not locate, too tightly then fastening force produces stress concentration point, makes flexible rod 7 distortion or damage, and the uneven locating effect that produces of fastening force is also bad.
Shown in Fig. 9,10, be existing the third flexible rod 7, it is to be provided with an eccentric part 9 at tubule 72 to combine with bassoon 71 again, and the end of bassoon 71 is provided with end cap 91, borrows to rotate tubule 72 and make eccentric part 9 prop up bassoon 71, makes bassoon 71 and tubule 72 location.Yet, this kind flexible rod not only is provided with trouble, the shortcoming that also exists packing strength to be not easy to control, can't prop up bassoon 71 when rotating strength hour eccentric part 9, greatly then eccentric part 9 amounts of rotation are excessive for strength, and surpass the part that this eccentric part 9 can push against, and as long as flexible rod 7 is slightly stressed, eccentric part 9 promptly can deflection and can't locate, thus can not rotate flexible rod 7 when using, otherwise flexible rod 7 will unclamp.
Main purpose of the present utility model is, provide a kind of multipurpose flexible rod for solving the above problems, borrow locating piece to be located at the flexible rod jointing place, bestow the uniform clamping force of locating piece by fixed block, make its relative position be restricted and locate, because of flexible rod stressed comparatively even, can avoid damaged member and locating effect firm, in addition, need not use end cap during use, have easy to use, the easy effect of adjusting.
