Abstract
The invention discloses a length adjustment device, which is characterized by the following: setting at least one inner tube in the housing pipe; setting the locating system between housing pipe and inner tube; making the locating system as screw-thread locating system or circlip locating system; setting inner screw-thread on the housing pipe; matching the end of each inner tube with the outer screw-thread corresponding to the inner screw-thread on the housing pipe, which accomplishes the goal of length adjustment.
Description
Technical field
The present invention relates to a kind of length adjustment device of rod-like member.
Background technique
The length adjustment device of rod-like member has several classes usually: 1, Mohs cone type adjustable lever, be usually used in fishing rod, it is the anti-rotational force square that utilizes the principle generation of Mohs cone, the rotary connector that generally is used for machinery, drill chuck as drilling machine, the pawl dish of lathe, but it can only resist rotating force, and certain service orientation is arranged.And for example fishing rod it just carry out coarse to Mohs body (outer wall of tube wall and another intersegmental part carry out hacking), produce frictional force, make between the bar joint and produce snap-in force, but its force direction is limited, erect when adding the down pressure that the spin off body weight produced as bar, the frictional force of bar just can not support, and landing downwards or the indentation voluntarily of whole bar makes bar can not fixedly bear the state of pole gravity.Its characteristics of summarize are: otherwise whole bar all pulls out, or all indentations, can not regulate fixing by joint.2, pull-rod type adjustable lever, be generally used in umbrella, institute's regulation range is limited, it is to draw the chute that produces when utilizing metal tube to make, carry out the orientation of pole and slide, bar and bar support and utilize the Spring Steel Wire structure to support, and regulation range is limited, can only regulate two to three pair rod, be not suitable for having electric field to use.3, the jointing type adjustable lever it be that bore same pipe is connected, as the Placement of running water pipe, it utilizes the outside nut of pipe and internal thread to be connected and fixed, dismounting bothers not flexible, carries inconvenience.
Summary of the invention
The objective of the invention is to design a kind of length adjustment device of rod-like member, the end by pipe in every joint is provided with the outside thread that can cooperatively interact with the internal thread on the outer sleeve, realizes the purpose of free adjustment length.
According to design proposal provided by the present invention, in outer sleeve, have at least one joint and manage, between outer sleeve and interior pipe, positioning means is arranged.
Described positioning means is thread type positioning means or circlip type positioning means.In the thread type positioning means, there is internal thread the upper end of outer sleeve, in every joint the end of pipe have can be respectively with outer sleeve on the outside thread of screw-internal thread fit.Perhaps, the upper end of outer sleeve attaching nut, the upper end of pipe connects respectively and can have an externally threaded swivel nut with nut is connected in every joint.
In the circlip type positioning means, in the upper end of outer sleeve and the upper end of every joint inner sleeve draw-in groove is set respectively, in the lower end of every joint inner sleeve the elastic card that can embed in the draw-in groove is set respectively.
Advantage of the present invention is: since in every joint the end of pipe all be equipped with nominal diameter identical have an externally threaded swivel nut, in use, the swivel nut in all on pipes can be connected with the nut that is installed on the outer sleeve, therefore simplifies the structure.
Description of drawings
Fig. 1 is a structural drawing of the present invention.
State when Fig. 2 is in elongation for interior pipe.
Embodiment
As shown in the figure: in outer sleeve 3, have at least one joint and manage 7, positioning means is arranged at outer sleeve 3 and 7 of interior pipes.Described positioning means can a kind of thread type positioning means: the upper end of outer sleeve 3 attaching nut 5, the upper end of pipe 7 connects respectively and can have an externally threaded swivel nut 6 with nut 5 is connected in every joint.The lower end external diameter of pipe 7 greater than the upper-end inner diameter of pipe 7 in the adjacent following joint, forms bulge in the lower end of interior pipe 7 gradually in the last joint.When in needs elongate, managing 7, rotate with hand earlier and be positioned at pipe 7 topmost, the swivel nut 6 of pipe 7 upper ends in this joint and the nut on the outer sleeve 3 are separated from each other, pull out pipe 7 in this joint then, after the bulge of pipe 7 lower ends is clamped on the upper end of pipe 7 in the second adjacent joint in this joint, stop dead man, at this moment pipe 7 effects because of bulge are fixed together not landing easily in Zui Shangduan the interior pipe 7 and second joint.As length not enough, then can continue to pull out pipe 7 in second joint, in pulling out second for the joint pipe 7 o'clock with pull out first segment in pipe the same, rotate earlier this and save interior the pipe, make pipe in this second joint on 7 swivel nut and the nut on the outer sleeve be separated from each other, pull out pipe in this joint again, in this bulge that saves 7 lower ends is clamped on the 3rd joint that is adjacent, behind the pipe, stop to pull out pipe 7 in this joint equally, still not enough as length, then can operate and pull out pipe in the 3rd joint, and the like, up to the length of the bar position that meets the demands.
Described positioning means also can be a kind of circlip type positioning means: the upper end of pipe 7 is provided with draw-in groove respectively in the upper end of outer sleeve 3 and every joint, in the lower end of every joint inner sleeve the elastic card that can embed in the draw-in groove is set respectively.When needing the length of extension rod, pipe 7 in can pulling out, the elastic card in making on the pipe 7 embeds in the draw-in groove, utilizes elastic card and draw-in groove to locate.
Pipe is meant that in use outer sleeve 3 is positioned at nethermost state in the last joint as herein described, and at this moment, above all the other interior pipes 7 lay respectively at, and pipe is positioned at next joint pipe in the last joint, descends the interior pipe of joint to be positioned at outer sleeve most.
