Abstract
The utility model relates to a multi-purpose telescopic rod whose length is adjustable, composed of a sleeve rod 2 and a core rod 4. The utility model is characterized in that the end part of the core rod 4 which is arranged in the sleeve rod 2 is provided with a rotary expanding and fixing device to replace a traditional nut fixing device, and the other end of the core rod 4 is provided with a screw 5, a fine adjustment nut 6 and a movable top cap 7. The multi-purpose telescopic rod can be used as a supporting rod; when the fine adjustment nut 6 is screwed off, the utility model can be matched with the screw thread of a window cleaning device, a broom and a printing plate in order to be used as the handle of the articles.
Description
The utility model relates to a kind of adjustable length flexible rod member.
At present, the flexible rod of selling on the market generally is made up of core bar and loop bar two-part.The flexible control of core bar is to realize by the nut that screws on the loop bar that is arranged at core bar and loop bar joint.This flexible rod must unscrew the nut on the loop bar earlier when changing its length, could extract core bar out to the length that needs, and screws the nut on the loop bar then again, can fix its length, thereby cumbersome.Secondly, because turning repeatedly of nut very easily worn and torn, in case sliding tooth, flexible rod has just lost effect fully, and therefore, working life is shorter.
In view of this, the purpose of this utility model provides long multi-purpose telescopic bar of a kind of not nutted easy to use and life-span.
For achieving the above object, the utility model has been taked following measure:
1, the end of the core bar in being installed on loop bar is provided with one and rotates the tensioner fixing device, to replace existing nut fixing device.
2,, be provided with screw rod and fine-tuning nut at the other end of core bar, at the configurable movable top cap of fine-tuning nut end for making flexible rod adapt to multi-purpose needs.Revolve fine-tuning nut, screw rod can with supporting uses such as window cleaner, broom, brush board.
Through the utility model after the above-mentioned design, compact structure, of many uses, easy to use, and also greatly improve working life.
Provided an embodiment of the present utility model in the accompanying drawing.
Fig. 1 is a structure sectional view of the present utility model
Fig. 2 rotates cuing open of tensioner fixing device to show schematic representation
Be elaborated below in conjunction with accompanying drawing:
The multi-purpose telescopic bar contains loop bar 2 and core bar 4 of a dress crown cap 1, and the end that is installed on the core bar 4 in the loop bar 2 is provided with one and rotates tensioner fixing device 3; Rotating tensioner fixing device 3 is made up of eccentric switch block 8 that adopts engineering plastics (ABS) or nylon to make and the eccentric piston ring 9 of active open that is sleeved on the eccentric switch block 8.For flexible rod is served many purposes, at the other end of core bar 4, be provided with screw rod 5 and fine-tuning nut 6, be fitted with movable top cap 7 in the fine-tuning nut end.Spin off fine-tuning nut 6, the screw rod 5 on the core bar can be supporting with the screw thread on window cleaner, broom and the brush board etc., as their handle use.
Flexible, its operating method of fixation principle of multi-purpose telescopic bar: be state movingly owing to be installed on the rotation tensioner fixing device 3 of the core bar end in the loop bar with the loop bar inwall, thereby core bar 4 is flexible very free.Flexible during when core bar 4 to required length, core bar is turned an angle along clockwise direction, eccentric switch block 8 rotates thereupon together, makes eccentric piston ring 9 expansions of movable opening, is close to the loop bar inwall, thereby makes its location, fixing.Otherwise with core bar counter clockwise direction rotating certain angle, the eccentric piston ring 9 of active open shrinks, and core bar can freely stretch once more.
Claims (2)
1, a kind of loop bar (2) of a dress crown cap (1) and multi-purpose telescopic bar of a core bar (4) of containing, it is characterized in that the end that is installed on the core bar (4) in the loop bar (2) is provided with a rotation tensioner fixing device (3), the other end of core bar (4), be provided with screw rod (5) and fine-tuning nut (6), the end of fine-tuning nut (6) disposes movable top cap (7).
2, multi-purpose telescopic bar according to claim 1 is characterized in that described rotation tensioner fixing device (3) contains an eccentric switch block (8), on eccentric switch block (8), is set with the eccentric piston ring (9) of an active open.
