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 at present.The CN1133223A patent application discloses a kind of flexible rod of new structure, and it is to roll with sheet material to form.Utilize the elastic element of roll bar end, regulate roll bar required different elasticities in telescopic process.Its deficiency is because the special type of characteristics that it self is constructed and adjusting roll bar elasticity, the elasticity that elastic element can provide is limited, thereby the magnification that telescopic scrolling rod can provide can not be very big, and magnification is big more, regulate difficultly more, use trouble more.
It is a kind of that purpose of the present invention will provide exactly, and the elasticity of the hollow cylinder body rod that rolls with sheet material is adopted the telescopic rod of new regulative mode, and it has the big characteristics of magnification.
The object of the present invention is achieved like this: a kind of telescopic rod, it is the hollow cylinder body rod of a scalable certain-length being rolled into by one section sheet material that can curl, it is characterized in that: fix one at the outermost surface of this hollow cylinder body rod and can regulate this hollow cylinder body rod and respectively roll up the control unit of interlayer elasticity, this control unit can be with the metal of various sections, plastics or other material are made, its vertical section 2 of having at least the same directions of two axis to arrange with this hollow cylinder body rod, parallel side by side in their partial-lengths at least therein, and it is as a whole by 3 one-tenth of the horizontal linkage sections at least one place, wherein have at least a vertical section 2 to be fixed together, have another vertical section 2 internal layer that inserts these hollow cylinder body rods at least along the axis of this hollow cylinder body rod and the end 1 or close terminal 1 the position of the outermost sheet material that curls of the body of rod.
The present invention is like this work: when along telescopic rod roll direction rotation telescopic rod terminal the time, the body of rod begins rolling-in, and the drive control unit is synchronized with the movement, when the complete rolling-in of the body of rod, insert vertical section (be called again below this paper for sake of convenience and insert section) also clamped fixing of the control unit of telescopic rod internal layer, and its vertical section (the calling holding part for sake of convenience below this paper again) and the body of rod end that are fixed on body of rod end strained simultaneously, here the body of rod and control unit interact, and are fixed mutually.Insert section simultaneously and also make the outer end face of the body of rod be deformed into the irregular cycle more stable than circle by the circle of easy rotation, if at this moment there is not the external force effect, telescopic rod is fixed.The direction that rolls of contrary telescopic rod is rotated body of rod end, and the body of rod is loosened, adjust Len req after, again along telescopic rod roll the direction rolling-in body of rod, telescopic rod just can work or pack up.The mode of this adjusting telescopic rod elasticity is to utilize to insert moving in the Duan Zaijuan layer, and the circle that the several layers coiled material between holding part and insertion section is formed can enlarge or dwindle, thereby makes telescopic rod obtain required elasticity.Magnification is big more, control unit can be used to regulate the curled sheet material of elasticity naturally can be long more, control unit is regulated the ability of telescopic rod and is also strengthened thereupon, so no matter how long telescopic rod system have, always control unit can be on this basis considerably beyond this telescopic rod greatest requirements to different elasticities in telescopic process.Control unit of the present invention can be made, also can adopt bamboo and wood or other material with metal, plastics or their composite material of various sections, and a control unit can be used one or more material.Can with bend, compacting, injection moulding, cutting, bonding, welding, method such as hinged make.
The linkage section of control unit among the present invention, preferably to two vertical minor arc shapes of the Vertical direction bending of section, it is more identical that holding part and the insertion section and the internal layer of telescopic rod are contacted with cylindrical, more helps the terminal edge of telescopic rod is pushed down tension.
The present invention develops on the basis of the disclosed telescopic scrolling rod of CN1133223A patent application, and under the condition of same size, the diameter range that the present invention can clamp various rhabodoids is several times of telescopic scrolling rod.A for example same telescopic rod, as long as its long enough, its head end may be adjusted to the diameter that clamps a pencil, may also be adjusted to the diameter that can clamp tens pencils, this be telescopic scrolling rod can't compare, thereby application area can be more extensive.
Magnification of the present invention can reach more than 30: 1, head end and the essentially identical telescopic rod of end diameter when being particularly useful for being produced on body of rod elongation, particularly when this telescopic rod is longer, because its curled sheet material is an arc, the vary in diameter of body of rod end the invention solves the telescopic scrolling rod difficult problem of this situation of incompatibility especially greater than the telescopic rod of other shape when flexible.Advantages such as the versatility of core of the present invention---control unit is good, and the control unit of same specification can be respectively uses respectively on body of rod diameter differs several times telescopic rod, and the present invention simultaneously also has simple and reasonable, and integral body is firmly not fragile.

The present invention is described in more detail below in conjunction with drawings and Examples:
The present invention is when implementing, and the section shape at each position of control unit preferably adopts circle or rectangle, and circle has the intensity height, rectangle easily and body of rod profile match, also can according to circumstances adopt section is the material of other shape.For example for beautiful shape, being fixed on the terminal vertically section of section of the body of rod can adopt arc or curve the rectangle of arcuation, for making things convenient for the terminal rotation of the body of rod, vertically the section of section can also adopt many prismatics or trapezoidal, can also adopt different section shapes respectively as shown in Figure 3 at the different parts of a control unit.The present invention's vertical section of fixed core end when implementing is designed to handle and various pattern by usage requirement, or under various specific (special) requirements and its section shape of shape that forms is diversified especially, or even it is irregularly shaped, the section shape at each position of control unit can be solid also can be hollow, for example vertical as required section can be made the shape of section for annular, also can make screw thread as required, be used to connect other article at the interior circle of annular.
Control unit has two vertically sections and form an integral body by the horizontal linkage section at least one place at least among the present invention, basic shape can for U-shaped as shown in Figure 5, H shape or rectangle, their various deformable bodys, combination in addition in addition.For example the U-shaped deformable body has two vertically not isometric shapes of section, with " M " shape or flat serpentines with three vertical section formation, the deformable body of H shape has increases shape or two the vertically section prolongations respectively that form behind the horizontal linkage section, shortens or bend towards the shapes such as arc of any direction.The deformable body of rectangle has three vertically " day " fonts of section formation, article four, " order " font that vertical section forms, lack the horizontal linkage section of an end or lack the shape that certain part back forms, can also be two limits after wherein or some vertically section disconnects, extend to form two vertically overlapping crossing shapes of section forward.Can also be rectangle, " day " font, the horizontal linkage section in " order " font two ends by straight deformation camber, and arcuate segment can be to inboard, the outside or the Vertical direction bending of rectangle control unit as required.Can also be U-shaped, rectangle at least one vertically section cross and the horizontal tie point of linkage section, extend into the arc of straight shape or either direction or the control unit of other shape forward.Among the present invention in the rectangle control unit vertically the length of section preferably slightly be wider than the width of place flexible rod sheet material, and have only the control unit of the horizontal linkage section in a place not limited, but preferably be shorter than the width of place telescopic rod sheet material.Inserting in the control unit does not have too strict requirement between section and the holding part, general context is wider.All can satisfy usage requirement from one millimeter to several centimetres, when two vertical sections are connected by elastic ring and have elasticity, also can be close together as shown in Figure 2, this can also have clamping action to the sheet material between two vertical sections, but speed was slower when the body of rod loosened, should be according to the purposes of coiled material thickness, telescopic rod, the friction factor of sheet material, vertical section are inserted the number of plies of internal layer, the diameter of body of rod end, composite factors such as the section shape consideration design of control unit.At least one inserts section and can insert first internal layer counted from the telescopic rod outermost surface as required to any internal layer in the control unit, longer as telescopic rod, coiled material is thinner, when the portion of the handle needs of telescopic rod end are thicker, just can insert internal layer than multilayer, otherwise can insert the internal layer of less layer, it is many more to insert the number of plies under the identical situation of other condition, fastening function and stability are better more, but speed is slow more when loosening, it is few more to insert level, fastening function and stability are weaker more, but speed is very fast when loosening, when not needing to use on frequent flexible articles for use such as the scalable fishing rod, should insert more level, and the level that should insert when using is few on to often flexible repeatedly articles for use such as scalable flyswatter, inserts the strong point that to take into account the two apart from the internal layer of three-four layers of telescopic rod outermost surfaces generally speaking.
When at least one vertical section position with the terminal or close coiled material end of coiled material is fixed as one in the control unit, can adopt riveted joint, welding, method such as bonding, hinged, also can adopt the means of fixation that is easy to take off at any time as being threaded or snap-in connection.
When control unit is that U-shaped or other are when having only the control unit of place's linkage section, can directly directly be fixed on body of rod end after the insertion inserting section from the edge of the level that will insert, when control unit is rectangle or two ends when all having linkage section, can pass from the end of roll bar and from coil to coil moves to behind the predetermined internal layer terminal fixing with the body of rod.
The present invention is when implementing, and the insertion section in the control unit can be made waveform, with the frictional force between increase and the body of rod insert layer, is to increase frictional force, can also put rough elastic sleeve of a section surface or soft layer for inserting section, as shown in Figure 3.Linkage section also can adopt wave-like, can make the distance between vertical section become big under external force like this, can satisfy of the specific (special) requirements of specific telescopic rod to this respect, can also make scalable telescoping structure to vertical section or linkage section, has the variation that in use adapts to the curled sheet width of flexible rod end automatically, and the distance between the vertical section of adjustment, insert the shape that section can also change body of rod end, when the sectional area of especially insertion section is big, in order to make the telescopic rod end obtain specific shape, the section that inserts section also can adopt corresponding shape when implementing in the present invention.Control unit among the present invention, though it is different, but main effect is identical, all has the fundamental function of regulating the telescopic rod elasticity, and is different on concrete feature and using scope again simultaneously, this is producing various different purposes just for us, provide sufficient choice when unlike material, the telescopic rod of different size, when for example control unit is rectangle, because its sound construction is not fragile, thereby can extensively adopt.Though and the U-shaped structural strength when using on the flexible rod that has the requirement of putting as candlestick, flagpole base etc., does not very easily make candlestick, flagpole base etc. put steadily because of body of rod foot has the linkage section of control unit not as rectangle.When control unit has at least two to insert section, can insert the different internal layer of telescopic rod respectively as required, telescopic rod has characteristics such as steadily difficult slip of when loosening like this.The present invention is when implementing, and the holding part in the control unit can also be made and help the body of rod terminal rotation, hand-held comfortable handle shapes and have the decorative pattern shape of aesthetic feeling.Holding part also can be designed to corresponding shape according to the concrete purposes of place telescopic rod, and during for example as the scalable penholder or the pen cap, holding part just can be made the pen clip shape.When fixed end was two, under the condition that the telescopic rod end diameter allows, the distance between two holding parts preferably selected to hold the width of user's thumb, made to unscrew or screw roll bar and be more prone to convenient.
Holding part and insert section and can also cross linkage section and extend into one section with new function, as the hook 4 of telescopic rod, as shown in Figure 4, or as the connection part of telescopic rod and other article.
Curled sheet material Material Selection among the present invention, the making of the sheet form of can curling, rolling all of telescopic rod can be made with reference to CN1133223A patent application disclosed method, when selecting the curled sheet material of arcuation for use, near a section of coiled material end, promptly when regulating the telescopic rod elasticity, can be moved into part between fixed end and the insertion end and preferably make straightly, can when selecting control unit, reduce restriction like this.
The fairly simple embodiment of control unit is that metal wire rod is bent into rectangle or U-shaped among the present invention.
