Description
Technical field:
The utility model belongs to telescopic rod technical field, is related to one kind and exempts to punch Multifunctional telescopic rod.
Background technique:
Telescopic rod is common tool in people's daily life, and telescopic rod has adjustable in length, packaging volume small etc. excellent
Point has been widely used for clothes hanger, curtain rod, Bath-curtain rod, towel rack, the multiple fields such as projection screen bracket, due to user
The limitation of use space, the length of telescopic rod must adapt to the bulk of place to use, therefore the length of telescopic rod must can
It adjusts.
Telescopic rod on the market has following several at present: a kind of telescopic rod, by the mutually nested core pipe of push-tight and outer tube,
After holding out against two sides metope, to be fixed with the form of built-in setscrew, this structure is easy to make the fixed position deformation of core pipe screw, when
Between long easy stripped thread fall off and damage telescopic rod；Another telescopic rod is the opposite position that two bars are fixed by locking swivel nut
It sets, it is inconvenient to use since locking swivel nut is not easy to securely fix the relative position of two bars, easily there is slide bar phenomenon；Another
Telescopic rod holds out against the wall of its two sides, the pretightning force of this casing by the effect of the support spring between inside and outside casing outward
Because positioning the presence of pitch of holes, it and cannot finely tune, spring is accurately allowed to reach maximum pretightning force, enable the load-bearing of telescopic rod
Power is had a greatly reduced quality, if load-bearing is greater than the stiction that pretightning force generates at telescopic rod both ends, slide bar phenomenon will also occurs；Together
Shi Shangshu telescopic rod is not able to satisfy the installation needs of large scale length variation when clipping room is away from changing greatly.
Utility model content:
For the deficiency of prior art telescopic rod described in background technique, the utility model provides a kind of telescopic rod, this is stretched
Contracting bar can length fine tuning allow support spring to be compressed to bottom under conditions of meeting installation length to reach, guarantee elastic force most
Greatly, so that load-bearing is maximum, it is not easy to slide bar, and it is able to satisfy the installation needs of different length.
The utility model is achieved by the following technical solution, provide one kind exempt from punch Multifunctional telescopic rod, including in
Empty thick bar and the thin bar that is hollow and having spiral support spring changeover portion being set in thick bar, the thick bar and thin bar can
Opposite sliding along its length, the thin bar be equipped with elastic card bean inside thick bar contact jaw, on the tube wall of the thick bar side
It is distributed several card holes with the cooperation of aforementioned flexible card beans along its length；Not being serially connected with thin bar contact jaw for the thick bar is N number of
One end section of extension rod, the extension rod is identical as thick bar sectional dimension, and the other end has necking, and the necking penetrates thick bar
Or another extension rod forms tight fit；Flexible bar body is formed by the thick bar, thin bar and several extension rods；The telescopic rod sheet
Any end in the both ends of body and installation face contact is arranged with spiral fine tuning support base, and the opposite other end is arranged with fixation
Seat.
Further, the spiral fine tuning support base includes the sliding screw of rotary threaded sleeve and rotary threaded sleeve cooperation, described
Sliding screw includes stud and the guide tang affixed with stud, and the guide tang is slidably threaded through on support base.
Further, one end that the thick bar is contacted with thin bar, is additionally provided with fixing sleeve, the shape of the fixing sleeve and thick
Bar is similar, and has the cavity big with thick bar outer profile etc., and cavity bottom offers bore and the comparable circular hole of thin bar outer diameter, institute
It states thick bar end to be plugged in the cavity of fixing sleeve by tight fit, the thin bar passes through the circular hole of fixing sleeve cavity bottom.
Further, the spiral support spring in the middle part of the thin bar is fixedly connected with the thin bar body of rod at its both ends.
Further, N number of extension rod, length are different.
Further, the cross sectional shape of the thick bar and thin bar is circle/regular polygon.
Further, the spiral fine tuning support base and fixing seat are plastic part.
Further, modeling is provided on the end face of the spiral fine tuning support base and fixing seat being in contact with mounting surface
Expect friction pad.
The technical characterstic of the utility model: the telescopic adjustment part of the utility model telescopic rod is by thin bar thick bar nested groups
At, fixed elastic card bean in band spiral support spring and pipe in thin bar, there are multiple card holes above thick bar, elastic card bean presses card
Telescopic rod telescopic adjustment function is realized on different holes.One headband of extension rod has necking, for being segmented inserting prolonging telescopic rod.
Realize that telescopic rod entire length reaches different range value with the extension rod of different length, quantity.Telescopic rod spiral finely tunes support base
Screw thread screw technology realize telescopic rod fine tuning, allow spring-compressed to guarantee the maximum purpose of elastic force on earth to reach.It solves
Since each installation site size is not fixed, the long hole spring-compressed of telescopic rod installation Duola is still not placed into pole on earth
Adjust unhorizontal, elongating a hole spring less cannot compress that there are also compression spaces to cause telescopic rod is fixed not to be easy tightly to slide completely
The drawbacks of.
The utility model has the beneficial effects that one kind provided by the utility model is exempted to punch Multifunctional telescopic rod, it being capable of length
Fine tuning allows support spring to be compressed to bottom under conditions of meeting installation length to reach, and guarantees that elastic force is maximum, so that load-bearing is most
Greatly, it is not easy to slide bar, and it is able to satisfy the installation needs of different length.
