Description
The present invention relates to a kind of flexible rod, particularly relate to a kind of flexible rod that rolls with sheet material.
General flexible rod is to be made of by socket or hinged mode the more piece quarter butt mostly at present.The CN1042207C patent also discloses a kind of " telescopic scrolling rod ", it is to roll with sheet material to form, utilize the outermost elastic element of roll bar to regulate roll bar in the required different elasticities of telescopic process, thereby provide telescopic process required necessary condition, its deficiency is that structure is simple inadequately, and elastic element and the bad defective that is connected of the body of rod, because on the body of rod that elastic element can not be completely fixed, it need move automatically at the outermost surface of the body of rod, will prevent also that simultaneously it from use coming off from the body of rod.
It is a kind of simple in structure that purpose of the present invention will provide exactly, do not have the flexible rod that connects defective.
The object of the present invention is achieved like this; A kind of telescopic rod, it is with one section at least therein in the part length, with plastics or composite laminated plastics is the sheet material of material or the hollow cylinder body rod that can stretch in certain-length that film roll is made, it is characterized in that: in working process, at least to constituting outermost that part of sheet material of this flexible rod or film, with thermoforming or other processing mode, regularly be that its external diameter is not having under the state of outside, elasticity volume less than this flexible rod outermost surface minimum outer diameter in actual use, make to be in the outermost elasticity volume of this flexible rod, have the elastic potential energy that this flexible rod is exerted pressure all the time.
The present invention is work like this; Roll direction when rotating the outermost elasticity volume of the body of rod when contrary flexible rod, external force forces the external diameter of elasticity volume to enlarge, each volume layer pressure of the body of rod reduces, the gap of each volume layer becomes greatly, frictional force diminishes, at this moment just be easy to the body of rod is elongated or shortened, behind the adjustment Len req, the direction that rolls along the body of rod screws the body of rod again, body of rod outermost surface has the elasticity volume of elastic potential energy will be automatically the fixed in shape of this flexible rod, and flexible rod just can be worked and just packed up.
Compare with aforesaid " telescopic scrolling rod ", maximum characteristics of the present invention are exactly simple and reasonable, it has saved the elastic element of " telescopic scrolling rod ", the elasticity volume that it is used for controlling the flexible rod elasticity itself is exactly all or part of of the body of rod, thereby has eliminated " telescopic scrolling rod " elastic element and the bad defective that is connected of the body of rod naturally.And the performance of regulating body of rod elasticity also improves to some extent, because at first its elasticity volume is open, so it regulates the elastic element of the scope of body of rod elasticity above " telescopic scrolling rod ", secondly as required, can be chosen in body of rod outermost surface, or several layers, or some positions, or the body of rod whole make the shape that curls of the elasticity with self fastening function, thereby can satisfy the different needs of flexible rod when regulating elasticity of various different purposes.Because the body of rod of telescopic rod can increase new function.For example can print, paste, carry secretly operation instruction, calendar, miniature picture scroll, advertisement etc. in the interior outside of flexible rod coiled material.Also can be according to the purposes of flexible rod, use object, using scope print relative content, for example the traffic map etc. of telephone number commonly used, time-table, tourism can be printed in the outside in the body of rod of portable pen.Various study formula, English word, ancient poetry literary composition etc. can be printed in the outside in the body of rod of the omnipotent pen cap.Be available for users to open at any time watch.The article of also being fixed for replacing flexible rod internal layer provide convenience simultaneously, for example when changing the pen core of the portable pen of making according to the present invention.The present invention also has directly the linkage function with other article, for example can directly launch the outermost elasticity volume of portable pen to climb with key-ring or trousers that object such as band rolls up is one again, make carry convenient.Because each position of the present invention can adopt identical materials to make, its each position can reach basically identical service life.
During enforcement of the present invention, the typing of flexible rod outermost surface elasticity volume given diameter can be adopted thermoforming or other processing mode, can be when manufacturing sheet material or film straight forming, the secondary operations moulding that also can utilize the sheet material that made or film to carry out multiple mode.For example can limit heating edge roll-forming, when its external diameter of the body of rod of directly spooling can't be less than in actual use minimum outer diameter of this flexible rod, can be the flexible rod rewinding after the typing, promptly roll again from outermost surface, make innermost layer become outermost surface, can make the flexible rod outermost surface of spooling again have bigger elastic potential energy like this, when internal and external layer all needs big elastic potential energy, can be rolled into two cylindrical bodys to the two ends of that section coiled material respectively in opposite directions, after the thermoforming, again one of them cylindrical body is rolled onto on another cylindrical body, makes a nexine and the outer flexible rod that all has big elastic potential energy.
Can be as required during enforcement of the present invention, outermost surface or several layers to flexible rod, or the some positions or the typing of all curling, when for example short or used sheet material or film are soft at the body of rod, can be fixed to the elasticity volume by a outermost surface to the body of rod, when used sheet material is hard, when being rolled into each volume layer of the body of rod and having big elasticity, can make curly form to some positions of the whole or body of rod of the body of rod with elastic potential energy.
When making chalk sleeve etc. and need often to change the flexible rod that clamps article, innermost layer should keep the bigger elastic potential energy that expands outwardly, at this moment can directly utilize the hardness and the elastic force of sheet material, only the outermost surface to the body of rod is fixed to the elasticity volume, also can be simultaneously body of rod innermost layer within it the footpath greater than waiting that the external diameter state that presss from both sides thing finalizes the design down, the elastic potential energy that makes it is the direction that expands outwardly of place flexible rod, so that when unscrewing body of rod outermost surface, innermost layer can directly be expanded to required internal diameter, the insertion that helps waiting to press from both sides article.
The present invention is when implementing, can select multiple plastic sheet or film for use, as long as it has certain degree of hardness, can process the elasticity volume that can keep elastic potential energy for a long time and get final product, for example: can select polychlorovinyl sheet material and film, terylene sheet material and film, sheets of tac material and film etc. for use.
The present invention can also select for example material such as plastic-aluminum, paper of composite laminated plastics for use when implementing.Or the sheet material of some kinds of unlike materials or film link into an integrated entity, and form the different parts of flexible rod.The thickness at used sheet material or each position of film can be identical or inequality.Its vertical limit of sheet material that is adopted or film can be straight, also can have certain radian, constitutes the width of flexible rod innermost layer and outermost that part of sheet material, preferably is narrower than the width of other parts sometimes.
The present invention can utilize self construction features directly as telescopic supporting rod when implementing, as the omnipotent pen cap, lifting candlestick etc., also can be at flexible rod internal layer fixedly various tool or articles for use, make various portable scalable articles for use such as portable pen, the portable article in fields such as scalable teacher's pointer, portable fishing rod, portable racket, scalable hair are brushed lightly, scalable car-cleaning brush, scalable mosquito and fly swatter, scalable clothes hanging and other culture and education, light industry, tourism, army's logistics.
