Description

Telescopic scrolling rod

The invention belongs to the new construction of handle and bridge type objects.

The bridge class formation of the various tool handle of at present general vary in length and the vary in length of using on other article all is to be made of by socket or hinged mode the more piece quarter butt generally.The CN2065126U patent application also discloses a kind of roll bar, it is characterized in that utilizing self elastic force to form the bar of closure or semi-closed by the winding that one or several long limit links to each other.Above-mentioned bridge class formation, its weak point are to have simultaneously: advantages such as magnification is big, the direct multiple difform rod tool of profiling clamping of energy.

Purpose of the present invention is exactly that a kind of telescopic scrolling rod that has advantages such as magnification is big, the direct multiple difform rod tool of profiling clamping of energy simultaneously will be provided.

The object of the present invention is achieved like this: a kind of telescopic scrolling rod, it is characterized in that: by one section aluminium, mould or other sheet material that can curl is rolled into a telescopic hollow cylinder body rod, and promptly terminal 2 connect or be with a flexible member 3 that this hollow cylinder body rod is exerted pressure at the outermost layer of this hollow cylinder body rod.

Telescopic scrolling rod is in when elongation, exactly the cored screw body of rod that its two vertical limits overlap each other crossing.Screw or unscrew the end of roll bar, can be delivered to this power synchronously the head end of roll bar, when the head end of roll bar need clamp or loosen rod tool or articles for use, the end of rotation roll bar can be realized.When needs elongate or shorten roll bar, at first the direction that rolls of the contrary roll bar of the end of roll bar is rotated, make each lamellar spacing of roll bar become big, friction reduces, at this moment just be easy to roll bar is elongated or shortened, and then rotate the roll bar end along the direction that rolls of roll bar, and make the contact of each layer of roll bar tight, make the roll bar setting.When the rotation roll bar is terminal, should control the head end of roll bar or the clamping article that link together with head end: when of the present invention, can be easy to control the racquet frame that connects together with the roll bar head end as on racket, adopting.And there are not gripping object, gripping object to be not easy to control or gripping object when not linking to each other when the head end of roll bar sometimes with the roll bar head end, the surface that is preferably in the roll bar head end is shaped on the boss of being convenient to control, boss can also effectively prevent the roll bar head end volume cylinder of withdrawing fully, is unlikely to cause trouble to elongation next time.Roll bar more carefully, short, elastic element is tighter, when being not easy to rotate, the end surface of roll bar preferably also is shaped on boss.

The present invention is making shorter roll bar, required curl sheet material its do not require that laterally when too wide, the width of sheet material can be identical from head end to end.And when sheet material needs broad, preferably the head end of sheet material is made the width that is narrower than other position.It is flexible easier to make like this, and as required, the width at other position can be identical, or terminally is the wideest position for the wideest position or centre.

Should be as required when the present invention makes make vertical limit of the sheet material that can curl straight or have certain radian, the purpose of making radian is to make its head end of roll bar that is rolled more consistent with terminal diameter, and has the stronger function that roll bar is withdrawn under external force voluntarily that prevents.But it is convenient like that when shrinking simultaneously not as the roll bar that straight sheet material rolled.Should according to circumstances select, for example when making the pen cap, because roll bar is shorter, and to anti-withdrawal not too during big the requirement, vertical limit of its sheet material just can be made straight.If telescopic scrolling rod need be made when longer, or during as bearing bar and as scalable racket handle, preferably adopt the curled sheet material of specific arcuation.Also can only make arc,, can adopt only at one section curled sheet material of making arcuation near the sheet material end for example merely in order to prevent that roll bar is withdrawn voluntarily under less external force effect at the privileged site of sheet material.The prolonging direction of the roll bar that change arcuation sheet material rolls can obtain to roll curl up bar head end and the bigger roll bar of end diameter gap than straight sheet material.

The present invention is when making, can curling, each position of sheet material preferably is made of different materials sometimes, for example when making the higher telescopic scrolling rod of intensity, need to adopt the metal sheet of specific thicknesses, when needing the article of clamping thin again simultaneously, because the hardness of metal sheet, be not easy the need gripping object is clamped, at this moment just can connect the sheet material of one section other softer material at the head end of the sheet material that can curl, reach and the need gripping object can be clamped, can guarantee the purpose of roll bar intensity again.Also can connect one section softer sheet material at the end of roll bar, stressed evenly reliable in order to guarantee flexible member to the roll bar applied pressure.

The present invention also can be as required when making, and the curled sheet material of selecting for use is made of the several layers different materials.For example can be aluminium, plastic composite materials, it also can be the composite of copper or other metal sheet and plastics, do like this except can effectively preventing the embrittlement of metal sheet, available again plastic foil encases the edge of metal sheet, prevent the injury that the metal sheet edge might cause, can also be as required at the bulk body of the inboard compound one deck plastic foam class of hard sheet material, or other softer material, make the contact of each layer of roll bar good, increase frictional force, can certainly be only at the compound one section bulk body of sheet material privileged site, for example at the compound one section bulk body of the head end of sheet material, it is closely not loosening that clipped object is contacted with roll bar.At the terminal compound one section bulk body of sheet material, can prevent the loosening voluntarily withdrawal of roll bar effectively.End at sheet material also can adopt more easy method: promptly directly be encased inside one section bulk body at the roll bar end.

The present invention can select different the curled sheet material of each position thickness for use as required when making, for example when roll bar hand-held in when needing intensity higher with the position, and head end, when end needs intensity low, just can adopt two ends to approach the curled sheet material of thick middle.When rolling the head end roll bar more consistent, also can adopt it vertically to be divided into the sheet material of several portions different-thickness with end diameter.

The present invention is when making, can select for use as required on the surface and longitudinally be some sheet materials by the different colours of specific width distribution, the color that can expose according to each spiral section when roll bar is extended is adjusted the degree unanimity of each spiral section elongation, thereby is guaranteed the intensity unanimity at each position.And can avoid roll bar too to extend and disconnect.For preventing that roll bar from too extending and the elongation of accurate roll bar, the spacing tightrope that can also be connected a Len req with terminal inboard at the head end of roll bar, for example on scalable racket handle, connect a spacing tightrope, can guarantee the length of racket bar accurately, and can prevent that the phenomenon that causes roll bar to disconnect because of overexerting from taking place in batting.

The present invention should be according to the purposes of made roll bar when making, and the material of the specification of the requirement of intensity, roll bar and sheet material is decided the thickness of sheet material.Can also select transparent curled sheet material as required for use, so that can directly show the length of gripping object in the roll bar.Roll bar can adopt the direction of left-handed or dextrorotation to roll as required.

The flexible member that the present invention exerts pressure to the roll bar cylinder is an elastic rubber circle preferably, it also can be the elastic rubber closed section that is connected the roll bar end, can also be ring-type elastic force folder, or a ring-type, semicircular, polycyclic metal or plastic elasticity circle.

Thick or when the telescopic scrolling shank diameter because the sheet material that can curl when having big radian, can require to change bigger when flexible to the elasticity of flexible member, at this moment preferably select for use and can regulate the flexible member that cylinder is exerted pressure.When adopting the elastic rubber circle, can regulate elasticity with the method that change is looped around the number of turns of roll bar upper elasticity circle, also can regulate elasticity, or use the elastic force folder that to regulate elasticity with the end that changes roll bar elastic rubber closed section and the position of roll bar tie point.

Superiority of the present invention is: because the overlapping crossing position of each spiral section of roll bar can be adjusted to more consistent state, thereby make the intensity at each position of roll bar also be tending towards uniformity naturally.The present invention be easy to make the magnification of the telescopic scrolling rod of making reach 5: 1～10: 1 even bigger.A kind of scalable ballpoint pen of making according to the present invention for example, length is 30mm during contraction, diameter is 12mm, be easy to make a mao bar to reach 160mm or longer during elongation, maximum characteristics of the present invention are to utilize self structure, the direct various difform rhabodoids of profiling clamping, for example a pen cap can be distinguished chalk, the wax crayon of clamping different-diameter, and makes the chalk, the wax crayon that are held be not easy to fracture.Can also distinguish that clamping is cylindrical, the lip pencil body of many prismatics pencil and other triangle, four prismatics, flat.When using as instrument file handle; therefore can be and the production process of minimizing instrument file; reduce the length of instrument file, or a file is made up of variform two parts file sword, as required clamping part file sword; use another part file sword; after finishing using, can all be retracted into whole file body in the roll bar, play and carrying, depositing in the process; to the protective effect of file sword, and prevent to file the damage of sword to other article.The telescopic scrolling rod that adopts the present invention to make can also make head end more consistent with terminal diameter as required, makes the longer of telescopic scrolling rod system, thereby can enlarge the scope of application.The present invention is simple in structure, can be as the extendable handle of various portable instruments, various scalable penholder, various support bar, portable stand, and can adopt on the articles for use such as scalable all-weather hat at tourism tent, sunshade.Can also be as the packing of stock class article such as knitting needle, rung bar, carry, collecting utensil.
