Abstract
The utility model discloses a kind of flexible rod, the hollow stem of being successively decreased successively by some diameters is from outside to inside nestable to be formed, the front end of described hollow stem is provided with contraction mouth and rearward end is provided with belled part, time nestable, the front end of inner side hollow stem is positioned at the outside in anterior end of hollow bar portion, outside, and the belled position of inner side hollow stem is in the inside of outside hollow stem, be provided with two symmetrical v-depressions outside described hollow stem vertically, on the cross section of described hollow stem, V-arrangement face and arc surface are smoothly connected.The utility model is rational in infrastructure, is socketed fastening and capable of expansion and contraction, and intensity improves and cost reduces, and novel appearance.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of telescopic rod.
Background technique
Flexible rod applied range, can be used for mast, clothes hanger, Bath-curtain rod, mosquito net pole, fishing rod or curtain fittings etc., has scalable, and purposes is wide, the advantage such as to take up room little and liking by people.The hollow stem that existing flexible rod successively decreases successively by some diameters is from outside to inside nestable to be formed, nestablely under the cooperation of the belled part set by the rearward end of the contraction mouth set by the front end of outside hollow stem and inner side hollow stem to be connected, because described hollow stem is straight shape pipe fitting, connection between the hollow stem of interior outside is very not fastening, and strength deficiency when tube wall is thinner, on the other hand, outward appearance also seems more dull.The present inventor had once invented a kind of flexible rod being provided with a groove in hollow stem, though the problems referred to above make moderate progress, failed fundamentally to be solved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of telescopic rod, rational in infrastructure, is socketed fastening and capable of expansion and contraction, and intensity improves and outward appearance one is new.
The technological scheme that the utility model technical solution problem adopts is: a kind of telescopic rod, the hollow stem of being successively decreased successively by some diameters is from outside to inside nestable to be formed, the front end of described hollow stem is provided with contraction mouth and rearward end is provided with belled part, time nestable, the front end of inner side hollow stem is positioned at the outside in anterior end of hollow bar portion, outside, and the belled position of inner side hollow stem is in the inside of outside hollow stem, it is characterized in that: be provided with two symmetrical grooves outside described hollow stem vertically.
Preferably, the sectional shape of described groove is V-shaped.
Preferably, on the cross section of described hollow stem, V-arrangement face and arc surface are smoothly connected.
Described belled part preferably can be arranged at the structural member in the symmetrical hole of set by described hollow stem rearward end two with the arc-shaped spring piece of projection by two panels, or be two ring-type convex tendons, or be the conjunction be made up of a ring-type convex tendon of described structural member and inner side thereof.
The bore of contraction mouth set by described anterior end of hollow bar portion matches with the external diameter of socket hollow stem within it; Belled part set by described hollow stem rearward end matches with the internal diameter of the hollow stem be socketed in outside it.Described matching when referring to the rear close contact of socket and stretch can be slided or locate.
In described hollow stem, a front end contraction mouth place of inner side is provided with sealing cap, and the rearward end of outermost is provided with terminal part.Described terminal part can be the afterbody of described flexible rod, also can be the joint of described flexible rod and related device.
Preferably, described hollow stem is metal hollow bar or macromolecular material hollow stem.
More preferably, described metal hollow bar is stainless steel hollow stem or copper hollow stem, and described macromolecular material hollow stem is carbon fiber hollow stem or engineering plastics hollow stem.
The beneficial effects of the utility model are: rational in infrastructure, are socketed fastening and capable of expansion and contraction, and intensity improves and outward appearance one is new.Do not establish groove relative to hollow stem or only establish the flexible rod of a groove, if hollow stem pipe thickness is identical, then flexible rod intensity improves greatly; If keep flexible rod intensity suitable, then hollow stem pipe thickness can suitably reduce mutually, thus can reduce costs.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment structural representation of the utility model.
