Abstract

The utility model discloses an expansible cane, comprising an upper tube, an upper middle tube, a middle tube, a lower middle tube and a lower tube which are made of octagonal aluminum alloy tubes. The upper tube, the upper middle tube, the middle tube, the lower middle tube and the lower tube are sleeved into a five-segment cane body in sequence, further the lower portion of each of the upper tube, the upper middle tube, the middle tube and the lower middle tube is provided with a pin hole, the upper portion of each of the upper middle tube, the middle tube, the lower middle tube and the lower tube is equipped with an expansible pin, and the pins automatically extend out to clamp the tubes of the cane body during cane expansion, thereby realizing elongation of the cane, the tubes of the cane body can be drawn in by pressing the pins, thereby shortening the cane. The utility model has the advantages of simple structure, safety and firmness, quick extension, short body after retraction, and convenience for use and carrying.

Description

Telescopic walking stick

Technical field

The utility model relates to a kind of telescopic walking stick.

Background technology

Though existing telescopic walking stick is various, also have weak point, need tighten by joint during elongation, short inadequately after the retraction, therefore use and carry and also owe convenient.

Summary of the invention

The technical problems to be solved in the utility model provide a kind of structure clear, safe and reliable, stretch out fast, retraction short, use and carry all telescopic easily walking stick.

The technical scheme in the invention for solving the above technical problem is: this telescopic walking stick comprise pipe, in go up pipe, middle pipe, in pipe and pipe down down, they are sleeved on together successively, the main body of composition walking stick; Last pipe, in go up pipe, middle pipe, in pipe and following pipe all are the octagonal aluminium-alloy pipes down; Last pipe, in go up pipe, middle pipe and in all be processed with pin hole and go out lock-joint on the body of pipe down; In go up pipe, middle pipe, in down pipe and under the top of pipe all be processed with the bayonet lock installing hole; In on pipe, middle pipe, in down the top of pipe and following pipe the monolateral flexible bayonet lock of being made up of outer bayonet lock, interior bayonet lock and bayonet lock spring all is housed; In on pipe, middle pipe, in down the top of pipe and following pipe all be stained with the antifriction adhesive tape.

The utility model compared with prior art has following advantage: at first, the cane body adopts the combination of octagonal aluminium alloy extrusions suit, makes the interaction vertically exactly of each pipe, thereby guarantees that bayonet lock can align with pin hole, and eject and to block, fast pulling out and pinning and create conditions for walking stick; The second, after the retraction of this walking stick, length is 23 centimetres only, is easy to carry; Three, employing antifriction adhesive tape is filled the space between each encasement tube, can eliminate rocking of walking stick elongation, has reduced the friction between the tube wall again; The 4th, this walking stick has realized that five joint bail types connect, and has simplified the structure of walking stick, has reduced the kind and the quantity of part.

Description of drawings

Fig. 1 is the outline drawing after this telescopic walking stick elongation;

Fig. 2 is the outline drawing after this telescopic walking stick shortens;

Fig. 3 is the local amplification view of Fig. 1;

Fig. 4 is the local amplification profile of Fig. 3.

Among the figure: pipe on 1 handle, 2, go up in the pipe, 4 in the pipe, 5 down pipe, 6 times pipes, 7 footing, 8 interior bayonet locks, 9 outer bayonet locks, 10 bayonet lock springs, 11 pin holes, the outlet of 12 bayonet locks, 13 bayonet lock installing holes, 14 antifriction adhesive tape in 3.

The specific embodiment

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, this telescopic walking stick by handle 1, on manage 2, in go up pipe 3, middle pipe 4, in down pipe 5, manage 6 down, parts such as footing 7, interior bayonet lock 8, outer bayonet lock 9, bayonet lock spring 10 form; Last pipe 2, in go up pipe 3, middle pipe 4, in down pipe 5 and down pipe 6 covers dress up the main body of the telescopic walking stick of this five joint; In go up pipe 3, middle pipe 4, in down pipe 5 and down the top of pipe 6 the monolateral flexible bayonet lock of being made up of interior bayonet lock 8, outer bayonet lock 9 and bayonet lock spring 10 all has been installed.

Desire is extended walking stick, only need with two hands hold respectively handle 1 and footing 7 in go up pipe 3, middle pipe 4, in down pipe 5 and down pipe 6 from last pipe 2, pull out, because of flexible bayonet lock all being housed the top of respectively managing that is drawn out, in pulling, when flexible bayonet lock was aimed at pin hole 11 on the outer tube separately respectively, outer bayonet lock 9 just can stretch out pin hole 11 under the effect of bayonet lock spring 10 elastic force, the every joint aluminum pipe of cane body is blocked, can not retraction, thus the elongation of walking stick finished; Desire shortens walking stick, only need press outer bayonet lock respectively, and each pipe income is gone up in the pipe 2, can finish the shortening of walking stick.

The material of the name of this telescopic cane, the size of parts, use and manufacture method etc. can be different, yet represents being overlapped the cane body of dressing up by polygon pipe and antifriction adhesive tape and reaching the flexible bayonet lock of being made up of inside and outside bayonet lock and spring of the utility model technical characterictic.Three joints or the telescopic rod shape of more piece product that every employing said structure is realized all belong to protection domain of the present utility model.
