Abstract
The utility model provides a telescopic rod which comprises a screw rod; and a left-handed rotation threaded sleeve and a right-handed rotation threaded sleeve are arranged at two ends of the screw rod respectively. In the utility model, the threads are formed at the left end and the right end of the screw rod, and the friction force is great, so as to avoid the phenomenon of rod slippage of the general telescopic rod device; and moreover, the length of the device can simultaneously extend or contract by rotating a middle adjusting nut, the length of the device extends or the distance between two screw pitches contracts if the adjusting nut is rotated for one circle, so as to achieve the purpose of precision length of the adjusting device.
Description
Technical field
The utility model relates to a kind of expansion device, relates in particular to a kind of flexible rod.
Background technique
At present, known flexible rod structure generally is by hollow big bar, little bar, and the locking swivel nut is formed: the little bar of cover in the hollow big bar, the position of little bar in hollow big bar are fixed the relative position of two bars again by manual setting by the locking swivel nut.
There is following shortcoming in existing flexible rod device: at first, this device can only be adjusted length of telescopic bar roughly, and accurately regulating rod is long; Secondly, because pole face is smooth, the locking swivel nut is not easy firmly to fix the relative position of two bars, uses inconvenience, is prone to the slide bar phenomenon.
The model utility content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and the flexible rod of a kind of accurately controlling rod length and fixation is provided.
Technological scheme: flexible rod described in the utility model, comprise screw rod, it is characterized in that: the two ends of described screw rod are respectively arranged with left-handed thread sleeve and right-handed thread sleeve, can be long by the free regulating lever of forward and reverse screw thread.
The external thread length at the described screw rod two ends internal thread length with described left-handed thread sleeve and right-handed thread sleeve respectively is consistent; Swivel nut one end is a handle, and the other end screws in the screw rod outside thread.
For the relative position of standing screw and swivel nut, also be provided with left-handed locking nut between described screw rod and the described left-handed thread sleeve; Also be provided with the dextrorotation locking nut between described screw rod and the described right-handed thread sleeve.After screw rod and swivel nut screw, add and hold locking nut, because the double-layer safety of lock nut and screw thread, therefore be fixed up the position of swivel nut and screw rod.
Rotary screw also is provided with the adjustment nut for convenience, and described screw rod is made up of two screw rods that are fixedly connected on the two ends of adjusting nut.
During work, revolve the handle of swivel nut about clamping, nut is adjusted in rotation, and this screw rod can screw in swivel nut or back-out simultaneously, and the length of flexible rod device screws and changes with screw thread.
Beneficial effect: the utility model compared with prior art, its beneficial effect is: 1, end is screw thread about screw rod of the present utility model, frictional force is big, the slide bar phenomenon that can not only avoid general flexible rod device to be prone to, and, can elongate or shorten the length of device simultaneously by the adjustment nut in the middle of the rotation, whenever revolve the adjustment nut that turns around, the distance of two pitch of device length extension/contraction reaches the purpose of precision adjustment unit length; 2, the utility model is simple in structure, and length that can accurate control flexible rod device can especially can elongate or shorten the rod end distance arbitrarily by rotation adjustment nut by the long expansion device of the free regulating lever of forward and reverse screw thread, and is easy to use.
Description of drawings
Accompanying drawing is the screw-rod structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing, the mode by embodiment is elaborated to technical solution of the present invention, but protection scope of the present invention is not limited to described embodiment.
Embodiment 1: as shown in the figure, a kind of flexible rod comprises screw rod 1, and the two ends of described screw rod 1 are respectively arranged with left-handed thread sleeve 2 and right-handed thread sleeve 3, and the external thread length at the described screw rod 1 two ends internal thread length with described left-handed thread sleeve 2 and right-handed thread sleeve 3 respectively is consistent.
Also be provided with left-handed locking nut 4 between described screw rod 1 and the described left-handed thread sleeve 2; Also be provided with dextrorotation locking nut 5 between described screw rod 1 and the described right-handed thread sleeve 3.
The processing method of described screw rod 1 is: weld polished rod about adjustment nut 6, the end of polished rod processes left-handed thread and right-handed thread respectively, and this weldment is generically and collectively referred to as screw rod 1.
After screw rod and swivel nut screw, should add the relative position of holding locking nut standing screw and swivel nut.Because end is screw thread about screw rod, frictional force is big, the slide bar phenomenon that can not only avoid general flexible rod device to be prone to, and by the adjustment nut in the middle of the rotation, can elongate or shorten the length of device simultaneously, whenever revolve the adjustment nut that turns around, the distance of two pitch of device length extension/contraction reaches the purpose of precision adjustment unit length.
