Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is further described:
a kind of telescoping tube as shown in Figure 1, 2, comprising outer tube 1, being arranged in outer tube 1 and relatively can carrying out the interior pipe 2 of sliding extension and the lock controller for being locked by relative for interior pipe 2 outer tube by outer tube 1.
as shown in Figure 3,4: telescoping tube also comprises pipe box 4, outer tube 1, interior pipe 2 and lock controller are connected by pipe box 4.In the present embodiment: the end of interior pipe 2 is provided with two protuberances 20 radially protruded, the internal face of pipe box 4 have two breach 40 that permission two protuberances 20 pass through, during installation: the protuberance 20 breach 40 of pipe box 4 being aimed at interior pipe 2, and be enclosed within interior pipe 2, rotate a certain angle again, because pipe box 4 have rotated certain angle, the breach 40 on pipe box 4 misplaces with the protuberance 20 on interior pipe 2, and such pipe box 4 would not depart from from interior pipe 2.
in the present embodiment: the push button 33 that lock controller comprises needle roller 30, is pressed in the locating piece 31 on needle roller 30 top, is pressed in the pressing plate 32 on locating piece 31 and is located on pressing plate 32, push button 33, pressing plate 32 and locating piece 31 are connected, and push button 33 exposes outer tube 1, for operation.As shown in Figure 5: on locating piece 31, offer the needle roller hole 311 can accommodating needle roller 30, the outer wall of interior pipe 2 has several grooves 21 along its axially-aligned, and when needle roller 30 is between locating piece 31 and groove 21, now, the relative outer tube 1 of pipe 2 locks; When promotion push button 33 drives locating piece 31 to slide, make needle roller 30 depart from groove 21 and fall in needle roller hole 311, now, outer tube 1 can sliding extension relatively for pipe 2.
pipe box 4 offers the first through hole 41, and what locating piece 31 can be dismantled is arranged in this first through hole 41, and matches with it; And there is muscle position 310 bottom locating piece 31, as shown in Figure 5, interior pipe 2 outer wall offers the muscle position groove 22 extended vertically, and muscle position groove 22 only can be opened in the stage casing of interior pipe 2 outer wall, without the need to extending to two ends, muscle position 310 is positioned at muscle position groove 22, when promoting push button 33, locating piece 31 is slided along muscle position groove 22 by muscle position 310, and both can limit interior pipe 2 can only be elastic relative to outer tube 1, can not rotate by circumferencial direction, also can play the effect of guide-localization.During installation, rotate the angle of pipe box 4, make the first through hole 41 just to the position of muscle position groove 22, loaded by locating piece 31 in first through hole 41, the muscle position 310 of locating piece 31 coordinates with muscle position groove 22; During dismounting, locating piece 31 is laid down, rotate pipe box 4, after protuberance 20 and breach 40 align, can pull down.
as shown in Fig. 6,8: outer tube 1 offers the second through hole 10, pipe box 4 has draw-in groove 42, one the block 5 of elastic deformation can have the convex tendon 50 outstanding to its both sides, when outer tube 1 is set in after on pipe box 4, block 5 inserted the second through hole 10 and make convex tendon 50 be stuck in draw-in groove 42, like this, can prevent pipe box 4 from extracting in outer tube 1, pipe box 4 and outer tube 1 are fixed, can not come off easily time flexible.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
