Technical field

The tent that the present invention relates to a kind of contraction pole and adopt this contraction pole to make.

Background technology

Some rely on the provisional object of frame supports, have removable characteristics as advertisement boards, camping tent etc., their many employings have the bar of certain-length and the connector of bar is assembled into framework, billboard or tent cloth then adopt mode such as fasten to be attached on the framework, though this removable framework has component dismounting back volume to urinate in the characteristics of folding and unfolding, but every bar still has certain-length, and can not to shrink the characteristics of being convenient to folding and unfolding more not fairly obvious because of bar.

CN1027657C Chinese invention patent manual discloses the innovation and creation that name is called " back bone type tent canopy support frame ", its disclosed support is made up of several plastic pipe joints or metal tube coupling, they are cascaded and strain with wire rope, overarch, the rigid support of multiple shape such as triangle, polygon, produce flexibility when loosening, collapsible folding and unfolding its essence is a kind of site-assembled prestressed structure.Bar with this structure can be assembled into the required framework of tent, this scheme can be dwindled the folding and unfolding volume further with support after taking apart or tent, use deficiencies inconvenient, that operating procedure is many but still exist, particularly when bar is longer, there is not rule at the state that loosens after folding, easily knotting and generation are unfavorable for propping up next time the situation of framework, and giving next time, tension brings inconvenience.

Summary of the invention

Main purpose of the present invention provides the convenient and orderly contraction pole of folding and unfolding of a kind of hard and soft conversion;

Another main purpose of the present invention provides a kind of tent that adopts this contraction pole to make.

For achieving the above object, contraction pole provided by the invention comprises a plurality of rigidity joints with two axial ends and side, an axial end of each joint has protuberance, another axial end has the recess that coincide with protuberance, and each joint has two through holes that connect two axial ends.All joints are protruding, recess relatively sequentially is concatenated into bar by two flexible cables along through hole.In addition, also has a storage part, it is positioned at an end of contraction pole, be used for contraction pole can be curled the ground folding and unfolding wherein, storage part has a rotatable rotary axle, one storage bar cover is fixed on the axis of rotation in the interlock mode of intermittently-driving, and an end of two flexible cables passes storage bar cover and is fixed on the axis of rotation, and storage bar cover can be rotated to support between two blocks of guard wire plates at its two ends.A tensioned portion, it is positioned at the other end of contraction pole, and the other end of two flexible cables is fixed in tensioned portion.

By above scheme as seen, the present invention also is the basic structure that adopts the bar of flexible cable series connection joint, and when flexible cable tightened up, the protuberance of each joint and the engagement of the recess of adjacent joint, recess then meshed with the protuberance of another adjacent joint, and bar is rigidity; When flexible cable loosened, the convex-concave portion of each engagement unclamped, and can rotate the generation angle between the adjacent face of adjacent joint, and promptly bar is flexible, collapsible or tortuous state.And the present invention mainly is conceived to make the hard and soft map function of bar simple, and the rale store of bar under gentle attitude, for this reason, end at bar is provided with storage part, and it drives a storage bar cover by axis of rotation in the mode of intermittently-driving, and an end of two flexible cables passes storage bar cover and is fixed on the axis of rotation, storage bar cover can be rotated to support between two blocks of guard wire plates at its two ends, when axis of rotation drove the rotation of storage bar cover, bar can put around the storage bar, and spacing between the guard wire plate.The other end at bar is provided with a tensioned portion.This has solved gentle attitude lower beam on the one hand and can be collected in the storage bar cover tortuously, retractable operation is oversimplified, owing to adopted tensioned portion and amount of tension to equal the arc length stroke of axis of rotation idle running, solved the problem of hard and soft conversion dexterously, simultaneously, make that also the hard and soft map function of bar is very simple.

The scheme of optimizing is that intermittent drive mechanism is designed to axis of rotation and a pair of tooth that stores up the bar inner room, like this, after axis of rotation clockwise rotates the rotation of drive storage bar cover, the batch process that nearly 360 degree will be arranged when rotating counterclockwise, when a pair of tooth oppositely meshes, axis of rotation will drive storage bar cover and rotate counterclockwise; Vice versa.

The scheme of another optimization is that tensioned portion is designed to be made of the elastic component that a fixing feet and is connected between fixing feet and two the flexible cable ends, and when the flexible cable tensioning, elastic component is stretched, and bar is rigidity; When flexible cable loosened, flexible cable was convenient to the harvesting of bar more making relaxed constraints between each joint under the effect of elastic component restoring force.
