The specific embodiment

The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1, multi-function walking stick of the present invention comprises liner 1, long and short fixed

bar

6,10, and cylinder is shaken hands.

The fixing long and short fixed

bar

6,10 on both sides below the liner 1 is connected with expansion link 8 in short fixed bar 10, be connected with rubber bush 9 between expansion link 8 lower ends and the long fixed bar 6, has aperture every certain distance on the long and short

fixed bar

6,10 on both sides.

As shown in Figure 5, cylinder is shaken hands and is divided into three layers, form self-locking device by outside cylinder sleeve 5, interior cylindrical sleeves 3, spring 13 and metal tapered end 2, outside cylinder sleeve 5 is connected with interior cylindrical sleeves 3 matched in clearance, an end of interior cylindrical sleeves 3 and expansion link 8 link into an integrated entity (Fig. 4).There is baffle plate 12 centre of interior cylindrical sleeves 3, and interior cylindrical sleeves 3 can not rotate with baffle plate 12, simultaneously in cylindrical sleeves 3 directly weld with expansion link 8, by hands it is mentioned and puts down the indentation that can drive expansion link 8 and stretch out.One deck of the inside is a metal tapered end 2, stretches out the function that realizes the locking and unlocking with indentation by it, stretches out in the aperture that just can be stuck in long and short fixed

bar

6,10, thereby stops moving up and down of expansion link 8 and handgrip.What weld in the inboard of metal tapered end 2 is spring 13, and spring 13 other ends are welded on the baffle plate 12 of intermediary interior cylindrical sleeves 3, and baffle plate 12 is to be used for propping up spring 13, and spring 13 can be acted on elastic force on the metal tapered end 2.The steel wire 14 of in the middle of metal tapered end 2 inboard, also ining succession, an aperture has been opened at the center of baffle plate 12, and allowing steel wire 14 pass through, steel wire 14 passes aperture and walks around small column 11 and be wrapped on the outside cylinder sleeve 5 again.Rotation by outside cylinder sleeve 5 can spur steel wire 14, thereby putting in of traction metal tapered end 2 stretched out.

Have aperture every certain distance on the long and short fixed

bar

6,10 on both sides, metal tapered end 2 just was stuck in aperture the inside when expansion link 8 moved upward, and had just reached self-locking.For stability, be designed to tetragonal planform.Two bars are hollow, and spring 4 all is housed, high strength, and high resiliency is used for the people is lifted.

As Fig. 2, shown in 3, outside cylinder sleeve 5 inboards have a groove, and T type hook 15 is arranged in the groove, the steel wire 14 that connects together with metal tapered end 2 is to be wrapped on the T type hook 15, thereby and outside cylinder sleeve 5 connect together.When 5 rotations of outside cylinder sleeve, drive steel wire 14 and rotate together, thereby change the finite length of steel wire 14 in interior cylindrical sleeves 3, the contraction of steel wire 14 retracts metal tapered end 2 in the interior cylindrical sleeves 3, thereby withdraws in the aperture from long and short fixed

bar

6,10.

In Fig. 6, be provided with two columniform little bars 11 in the middle of the interior cylindrical sleeves 3, in the middle of two columniform little bars 11 symmetric groove is arranged, steel wire 14 passes between the aperture of two bars, 11 intermediary grooves formation, pass between the aperture on the middle cylinder of bottom again, be connected on the T types hook 15 in the outside cylinder sleeve 3.

As shown in Figure 7, long fixed bar 6 and have between the cross bar 9 of rubber bush and also be provided with bottom damping device 16.

The operation principle of self-locking device:

Long and short fixed bar 6 at the right and left, have aperture every certain distance on 10, metal tapered end 2 just was stuck in aperture the inside when expansion link 8 moved upward, just reached the requirement of self-locking, the quantity of aperture has determined the progression of the adjusting length of crutch, and the length of longitudinally arranging of aperture on bar has determined the total degree of contraction of crutch.Downstairs be because therefore low the and upper level of height of next stage stair requires crutch to extend.This just requires metal latch 2 to retract from the inside of the aperture on the long and short fixed

bar

6,10, reach this action, the armrest handle to realize.

Concrete application of the present invention:

At first shake hands by cylinder in the time of upstairs crutch moving telescopic bar 8 is upwards carried, spring 4 is compressed, simultaneously by metal tapered end 2, shake hands in cylindrical sleeves 3 and outside cylinder sleeve 5 handle and the expansion link formed move upward with respect to long and short fixed

bar

6,10 together.Because length at the right and left, short fixed bar 6, have aperture every certain distance on 10, metal tapered end 2 just was stuck in aperture the inside when expansion link 8 moved upward, just reached the requirement of self-locking, upstairs the time and the cross bar that is associated in together of rubber bush 9 also move up with expansion link 8, and long fixed bar 6 length remain unchanged, in the time of upstairs the expansion link 8 that shrinks is placed on the next stair, crutch is moved forward a segment distance a little, cross bar is put on the top one-level stair, the another crutch is also done identical action simultaneously, treat that carriage release lever all is placed on the stair face, rotate the hand-held pole release, the people is carried on the distance of one-level stair by spring 4 elastic force, repeat abovely then, can finish action upstairs.
