Background technique
Along with the raising day by day of people's living standard and the quickening of rhythm of life, the modern more and more adds attention to quality of life.So the flexible rod of selling on the market is varied, it all has different design concepts separately, makes every effort to reach the usage requirement of different user.At present, existing flexible rod, though can roughly satisfy usage requirement, but its design is all ingenious inadequately, all fail to break through traditional structural design, it constitutes by outer sleeve and the inner sleeve that is slidably cover successively by two joints and joins, and adopts drive fit to make two sleeve pipe relative fixed mostly in the cover portion of joining of two sleeve pipes, the collapsing length of this flexible rod is long for setting, and can not change.Also have be provided with the outer lock tube that externally threaded outer tube top is provided with tapped taper, interior pipe is inserted in outer tube and the outer lock tube, by screwing outer lock tube, its inner conical surface is closely contacted with interior pipe, increases the frictional force between the two, plays the purpose of fixing interior pipe.This mode China and foreign countries lock tube that is locked has certain elasticity and toughness, but in use fragile outer lock tube, thereby cause and accurately to locate, and interior pipe easily because stressed and rotate, displacement, influence is used, and the extension and contraction control trouble designs not enough hommization simultaneously, bring a lot of inconvenience to user's use, so be difficult to incorporate in the middle of people's the life.
The model utility content
The purpose of this utility model is, at above-mentioned deficiency, provides a kind of simple in structure, the flexible pulling force flexible rod in the free accurately location of easy to use and energy.
For achieving the above object, technological scheme provided by the utility model is:
A kind of pulling force flexible rod, it comprises that a pull bar and is movably set in sleeve pipe on this pull bar, the madial wall of this sleeve pipe is provided with and a plurality ofly axially moves towards the locating slot arranged along it, and is provided with the locating piece suitable with this locating slot corresponding to described pull bar.
Described locating piece comprises two claws, and it is symmetricly set on the described pull bar end face, and end does not outwards convex to form the flange that can conflict on described locating slot.Simple in structure, utilize the elasticity of claw self, can make the effective holding of flange on it on locating slot, realize the pull bar position and lock on required collapsing length, satisfying usage requirement.
Described sleeve pipe one end is provided with the department of assembly, and the other end is provided with for described pull bar and stretches out or its interior opening of retraction.Be provided with the department of assembly, be beneficial to other assembly and assemble mutually, design ingeniously, utilize to use.
At least be provided with one on the described pull bar along its axially extended guide slot, and be provided with the guiding projection suitable with this guide slot corresponding to described opening.Can effectively prevent pull bar because of stressedly rotate, bad phenomenon such as displacement, guarantee normally to use.
The quantity of described guide slot is four, and it is the center of circle and is symmetricly set on the described pull bar.Make the cross section of pull bar be one " ten " font structure, reasonable in design, structural strength is big, and stability is high, increases the service life greatly.
Described sleeve pipe comprises two housings, and this two housings covers mutually and fixes by a collar.Simple in structure, make simple and easy.
The beneficial effects of the utility model are: the utility model design is ingenious, be provided with positioning piece and a plurality of locating slot, locating piece can be according to different user demands, and free holding realizes the pull bar position and lock on required collapsing length on corresponding locating slot, satisfy accurately location and free spacing usage requirement, and the location is easy to use easily, simultaneously in use, pull bar also can not rotate and bad phenomenon such as displacement because of stressed, and stability is high; Overall structure is simple, rationally in addition, and long service life is made simple and easyly, and cost is low, is specially adapted to the toy technique field, as is applied in toy excavator, bulldozer etc.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
