Description

A kind of telescoping handle of strainer

Technical field

The utility model belongs to field of mechanical technique, is related to a kind of telescoping handle of strainer.

Background technique

When bundling or fixed cargo, multi-purpose rope, iron wire, are fixed, this mode by the way of manually tensing manually It is time-consuming, laborious, but it is difficult to bind cargo.After having invented strainer, cargo bundle is carried out by the tensioning function of strainer It ties up, i.e., convenient and safety.Therefore, the use of strainer becomes increasingly to come extensively, but the ratio that the handle of general strainer is done It is longer and all in this way, the volume of strainer is larger increase the cost of outer packing for a straight-bar；Due to occupying biggish sky Between the amount once transported an of vehicle is reduced, cause transportation cost to increase.Also, after strainer is finished, occupied space It is larger, it is covered up also inconvenient.

To solve the above problems, applicant had once designed and developed a kind of handle of tensioning device, and had applied for China Patent【Application number：200720113381.X】, which is socketed on tension in handle, including handle and lateral plate, one end of lateral plate On the spool of device, the other end is equipped with handle, and the lateral plate end is equipped with a connecting rod, and the barre dumpling of handle connects on connecting rod, Being cased with one in the money junction of barre and connecting rod can be mobile towards one end of barre or connecting rod and make its entirety leave barre With the sleeve of connecting rod money junction.The handle of tensioning device structure is simple, can fold up to save storage space.

But found in practice production, when cargo needs biggish tightening force, due to above-mentioned handle of tensioning device length It immobilizes, causes operator that can only manipulate strainer by limited decreased food in this way, it is relatively elaborate therefore urgent Need one kind that can change the handle of length freely to meet actual production operational requirements.

Summary of the invention

The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of flexible hand of strainer The technical issues of handle, the utility model solves is that handle how to be made to can be realized quickly and easily telescopic adjustment.

The purpose of this utility model can be realized by the following technical scheme：A kind of telescoping handle of strainer, including handle Bar is arranged with sleeve in the shank, and the sleeve is slidably connected with shank, which is characterized in that in the shank at least provided with Two locking pieces along shank length direction arranged for interval and the retraction shank that can be pressurized, the sleeve is on the position of inner end Equipped with lockhole, one of locking piece can be popped up from shank and be extend into lockhole.

The working principle of the telescoping handle of this strainer is led to by designing the sleeve being slidably connected with shank in shank The sliding of control sleeve is crossed, so that handle is able to carry out flexible, entire length can be changed；Meanwhile by shank up to Two locking pieces are designed less and design lockhole on sleeve, and by the cooperation of one of locking piece and lockhole, so that handle It can be locked after covering opposite shank telescopic adjustment, so that handle at least has two grades of length conditions；Specifically, work as handle When needing to extend, only it need to make locking piece retraction shank by Manual press locking piece so that locking piece unlocks with lockhole, this When second locking piece squeezed by sleeve and be in compressive state, then slide in and out sleeve again until second locking piece is from shank It pops up and extend into lockhole and realize locking, to obtain the longer handle of length；When handle needs to shorten, need to only press manually Pressure locking piece is detached from locking piece and lockhole, then slid inward sleeve again, if needed at this time if there is locking piece is outside sleeve To press these locking pieces again makes sleeve can continue to slid inward, then until another locking piece is popped up and protruded into from shank Locking is realized in lockhole, to obtain the shorter handle of length；Therefore, this telescoping handle can be real by pressure-locking part The telescopic adjustment of existing length, adjusts operation quickly and conveniently；In addition, operator can be made to use tension when this handle extends It is more laborsaving when device；When this handle shortens, strainer storage or packed and transported can be made more convenient.

In the telescoping handle of above-mentioned strainer, there is protrusion, the protrusion at the inner end port of the sleeve Interior to have opposite sleeves' inner wall inclined inclined-plane outward, the sleeve can be slided along shank squeezes locking piece by inclined-plane Retraction shank.When handle needs to shorten and have part locking piece to be located at outside sleeve, set by the inclined-plane on above protrusion Meter can be such that locking piece retracts automatically with the sliding of sleeve, will not cause to stop to the slid inward of sleeve, that is to say, that logical The above design is crossed, when handle shrinkage operation, without locking piece of the Manual press outside sleeve, so that the adjusting operation of this handle is more Add quick and convenient.

In the telescoping handle of above-mentioned strainer, there are two the locking piece tools and position is respectively close to the two of shank End.By although sacrificing the function of multistage adjusting, this handle being made to obtain longest with upper locking member number and Position Design The adjusting operation of most short two kinds of length is more quick and convenient.

In the telescoping handle of above-mentioned strainer, the locking piece includes plunger and spring, have in the shank with Locking piece installs shrinkage pool correspondingly, and the plunger is located in installation shrinkage pool, is fixed with gear at the aperture of the installation shrinkage pool There is convex shoulder and convex shoulder to be located between the bottom and baffle ring bottom end of installation shrinkage pool for the inner end of ring, the plunger, the spring One end be resisted against the bottom of installation shrinkage pool, the other end is resisted against on the inner face of plunger, and the spring can make the outer of plunger It pops up and is extend into lockhole from shank in end.By with upper locking member and locking piece mounting structure design, enabling locking piece It is hard to bear be compressed into shank and can spring force effect under automatic spring so that this handle is only by pressure-locking part just It is able to achieve quickly and easily telescopic adjustment.

In the telescoping handle of above-mentioned strainer, the head of the plunger has spherical surface.By designing above, make plunger It is easier to be detached from lockhole after compression, is conducive to improve the convenience that telescopic handle is adjusted.

In the telescoping handle of above-mentioned strainer, there is the item extended along shank length direction on the side of the shank Shape slot fixes finite place piece one in the strip groove, and the sleeve fixes finite place piece two, the limit on the position of inner end Position two part of part is located in strip groove and can be resisted against on locating part one.It is made up of the above locating part one and locating part two The design of position limiting structure can be avoided sleeve and deviate from shank because of misoperation during stretching.

In the telescoping handle of above-mentioned strainer, the locating part one is the spacer pin being plugged in shank or is spirally connected Stop screw in shank, the locating part two are the limit of the rivet being riveted on sleeve or integrated molding in sleeve Protrusion.According to actual processing and assembly needs, above-mentioned locating part one and limit two can be selected flexibly.

Compared with prior art, the telescoping handle of this strainer has the following advantages that：By in shank, sleeve, locking piece The matching design of this body structure and lockhole can make the behaviour of strainer so that this telescoping handle is easy to operate, quick and conveniently Make laborsaving, storage and convenient transportation.
