Abstract
The utility model relates to a novel simple and easy telescopic link in scalable accessory field, the inner tube that the inside pipe wall moved outside can following including the outer tube with in stretching into the outer tube, the rear end surface of inner tube is equipped with the more than one draw -in groove to have the flexible glue circle at the surface set of every draw -in groove, in close contact with is carried out with the inner wall of outer tube in the outer lane of flexible glue circle, and when the regulation inner tube was flexible, the inner wall extrusion flexible glue circle of outer tube made it to produce and warp, thereby produced the frictional force that is enough to fixed inner tube between the inner wall of messenger's outer tube and the flexible glue circle. Overall structure is simple, and the equipment is convenient, and it can fix not need to increase connecting piece such as any screw cap again, but consequently greatly reduced manufacturing cost, operation process is simple and convenient, directly stimulates inner tube and outer tube and can realize simple flexiblely, does not need to lock any part when flexible again, and the shrink back is whole small, does not influence the whole outward appearance of inner tube and outer tube, encloses the mutual wearing and tearing between reducible inner tube and the outer tube through the flexible glue, protects the product better, and life is longer.
Description
Technical field
The utility model relates to scalable accessory field, is specifically related to novel simple flexible rod.
Background technique
Flexible rod is a kind of structure of the changed entire length be made up of the above body of two joints, and it can regulate entire length as required, and therefore its application is very extensive.
The structure of current existing flexible rod divides two kinds, be the connecting pipe structure detachably becoming multistage freestanding bodies, it is carbon fiber bar that this structure uses maximum, carries after its multistage pipe needs to split respectively, engaged position is more, and dismounting inconvenience, in addition, because its every section is fixing length, length limited system after connection, when whole pipe install connect after entirety be most long status, when dismounting only remains the most short status of one section of Guan Shiwei, length accurately can not be controlled specifically on demand.Another kind is collapsible tubes body structure, can freely extend and shorten, be made up of inner and outer tubes, one locking element is set in an end of interior pipe, when the end of interior pipe penetrates in outer tube, locking element is used for locking interior pipe and outer tube, prevents it from relatively rotating or moves around, and wherein locking element is Camlock structure, overall volume is larger, multistage pipe also can take the space on a ground when shrinking, cause body overall volume also to become large, carry inconvenience.
In addition, the applicant submits to a invention and created name to be the Chinese utility model patent application of " flexible rod that can regulate arbitrarily collapsing length " in May, 2015, this patent has additional positioning cap and flexible glue circle between outer tube and the joint of interior pipe, flexible glue circle is compressed by screwed in place cap, flexible glue circle is made to produce distortion, thus interior pipe is locked, this structure need to manufacture independently positioning cap as locking fitting, also need tighten or unscrew positioning cap during operation simultaneously, operation inconvenience, structure is comparatively complicated, and manufacture cost is higher.
Summary of the invention
The purpose of this utility model solves above defect, provides novel simple flexible rod, and its structure is simple, easy to assembly, can any telescopic adjustment extremely any position.
The purpose of this utility model is achieved in the following ways:
Novel simple flexible rod, comprise outer tube and stretch in outer tube and can manage along in outer tube wall movement, the front end of outer tube is open front, the rear end of interior pipe penetrates in outer tube from open front, the rear end surface of described interior pipe is provided with more than one draw-in groove, and be set with flexible glue circle on the surface of each draw-in groove, the inner ring pairing of flexible glue circle is clamped in draw-in groove, the outer ring of flexible glue circle and the inwall of outer tube carry out close contact, when in regulating, pipe is flexible, the inwall extruding flexible glue circle of outer tube makes it to produce distortion, thus make to produce between the inwall of outer tube and flexible glue circle the frictional force being enough to fixing interior pipe.
Directly interior pipe is penetrated in outer tube during assembling, when needing to carry out telescopic adjustment, directly interior pipe or outer tube is manually pulled to make it be adjusted to adaptation length, the now outer ring of the inwall extruding flexible glue circle of outer tube, flexible glue circle is made to produce distortion, flexible glue circle after distortion and will producing between the inwall of outer tube be enough to fixing in the frictional force of pipe, be therefore adjusted to interior pipe and outer tube when adapting to position and not easily produce loosening after locking, thus reach fixed effect.
In above-mentioned explanation, as preferred scheme, described outer tube and interior pipe are pipe.
In above-mentioned explanation, as preferred scheme, the rear end surface of described interior pipe is provided with two draw-in grooves altogether.
In above-mentioned explanation, as preferred scheme, the outer surface of described flexible glue circle is provided with the tooth bar layer for increasing frictional force.
In above-mentioned explanation, as preferred scheme, described draw-in groove is arc groove.
In above-mentioned explanation, as preferred scheme, the cross section of described flexible glue circle is circular, and the inner circle size of flexible glue circle and the arc groove size of draw-in groove are matched.
In above-mentioned explanation, as preferred scheme, described flexible glue circle is made up of silica gel material.
The beneficial effect that the utility model produces is: interior pipe rear end is designed with flexible glue circle, directly fix interior pipe by the frictional force produced between flexible glue circle and outer tube wall, overall structure is simple, easy to assembly, do not need to increase the links such as any thread cap again can be fixed, therefore greatly manufacture cost can be reduced, in addition, operating process is simple and convenient, in direct pull, pipe and outer tube can realize simple flexible, and any length can be retractable in limited range, realize step-less adjustment, do not need time flexible to lock any parts again, after shrinking, overall volume is little, engaged position is less, easy to carry, do not affect the overall appearance of inner and outer tubes, the mutual wearing and tearing between interior pipe and outer tube can be reduced by flexible glue circle, protect product better, longer service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of flexible rod not-connected status in the utility model embodiment;
Fig. 2 is the structural representation of flexible rod elongation state in the utility model embodiment;
In figure, 1 is outer tube, and 2 is interior pipe, and 3 is flexible glue circle.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
The present embodiment, see figures.1.and.2, its novel simple flexible rod specifically implemented comprises outer tube 1 and stretches into can along pipe 2 in the movement of outer tube 1 inwall in outer tube 1, the front end of outer tube 1 is open front, the rear end of interior pipe 2 penetrates in outer tube 1 from open front, the rear end surface of interior pipe 2 is provided with a draw-in groove altogether, this draw-in groove is arc groove, and be set with flexible glue circle 3 on the surface of each draw-in groove, the inner circle size of flexible glue circle 3 and the arc groove size of draw-in groove are matched, the outer ring of flexible glue circle 3 and the inwall of outer tube 1 carry out close contact, when in regulating, pipe 2 stretches, the inwall extruding flexible glue circle 3 of outer tube 1 makes it to produce distortion, thus make to produce between the inwall of outer tube 1 and flexible glue circle 3 frictional force being enough to fixing interior pipe 2.
