Description

A kind of alpin-stock

Technical field

The utility model relates to a kind of alpin-stock.

Background technology

Along with increasing of people's outdoor activities, this activity of climbing the mountain more and more is subjected to liking of people.Alpin-stock has obtained general application as the aid of mountain-climbing, makes people's more laborsaving and raising security when mountain-climbing.Alpin-stock in the market generally all comprises handle, rod tube, some length is adjustable, some also subsidiary illumination performance, as the patent No. 200720113067.1, comprise standpipe group, the bar point assembly of some standpipes compositions of handle, head and the tail socket, the lower end of described standpipe group and bar point assembly are affixed; Also be provided with the LED signal lamp on the described mountain-climbing bar, the switch contact of described LED signal lamp is arranged on the handle.This alpin-stock just has illumination functions, but improves the comfort of mountain-climbing how, alleviates on the amount of exercise still not enough.

The utility model content

Technical problem to be solved in the utility model is the present situation at prior art, and a kind of alpin-stock of simple in structure, easy to use and safety and comfort is provided.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of alpin-stock comprises the last pole of handle, mutually socket, pole and be built in pole, descend the screw rod in the pole down; It is characterized in that hypomere is with spring in the described screw rod, make spring one end be connected the lower end of screw rod, and the setting of the spring other end is connected down on the pole, but is built in the pole with making down the pole elastic telescopic.

As improvement, described spring major part from top to down is with plastic wrapper, other has vinyl cover to be enclosed within on the screw rod, and be fixed on the upper end of plastic wrapper, the spring upper end is fixed between vinyl cover and the plastic wrapper, the upper end of plastic wrapper is resisted against down on the pole end face by the step confined planes, and the lower end that is fixed on screw rod behind the plastic wrapper by block is passed in the spring lower end; Be convenient to manufacture.

Further improve, be provided with the rotary stopper structure between described block and the plastic wrapper, be convenient to pole rotation up and down and flexible location.

Preferably, described rotary stopper structure adopts fixture block and draw-in groove structure, and the block upper end is distributed with fixture block, and accordingly, plastic wrapper is provided with draw-in groove.Or described rotary stopper structure adopts the latch engaging structure, and block upper end and plastic wrapper lower end are provided with the latch that can mesh and break away from.

At last, be provided with flexible detent mechanism between described screw head and the last pole.As comprise pad, collar, seat ring, down expansion loop, cydariform circle, go up expansion loop, screw head is provided with external screw thread, pass successively pad, collar, seat ring, down expansion loop, cydariform circle, go up expansion loop and combine fixing with the interior set internal thread of guide collar, upper and lower expansion loop is provided with notch, opens outside the notch when the pressurized of two ends.Flexible detent mechanism also can adopt other rotary flexible detent mechanism, and this report on the mountain-climbing bar is very many, gives an example no longer one by one.

Compared with prior art, advantage of the present utility model is: screw rod is provided with flexible member, when using alpin-stock, following pole can resiliently stretch, and increases comfort, alleviates people's amount of exercise and sense of fatigue, safety easy to use, and structural entity is reasonable and practical.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Embodiment 1

A kind of alpin-stock, comprise handle 1, go up pole 2, down pole 3 and be built in pole 2 and following pole 3 in screw rod 4, following pole 3 is built in the pole 2 by a spring 5 telescopicallies.The head of screw rod 4 forms external screw thread, pass successively pad 10, collar 11, seat ring 12, down expansion loop 13, cydariform circle 14, go up expansion loop 15 and combine fixing with guide collar 18 interior set internal threads, wherein collar 11 is fixed on the screw rod 4, be provided with in the last expansion loop 15 and the corresponding internal thread of screw rod 4 external screw threads, can rotate up and down; Upper and

lower expansion loop

15,13 is provided with notch, when the pressurized of two ends, open outside the notch, realize flexible location between screw rod 4 and the last pole 2, constituted flexible detent mechanism, certainly this rotary flexible detent mechanism can be designed to other structures, also is a lot of in prior art.Spring 5 is nested with the middle hypomere at screw rod 4, the upper end of spring 5 is fixedly connected on the plastic wrapper 6, spring 5 major part from top to down is with plastic wrapper 6, vinyl cover 7 is enclosed within on the screw rod 4, and be fixed on the upper end of plastic wrapper 6, spring 5 upper ends are fixed between vinyl cover 7 and the plastic wrapper 6, and the upper end of plastic wrapper 6 is resisted against down on pole 3 end faces by the step confined planes, and plastic wrapper 6 back is passed by 8 lower ends that are fixed on screw rod of blocking a shot in spring 5 lower ends.The lower end of plastic wrapper 6 is provided with the fixture block 8.1 that is provided with on several draw-in grooves 6.1 and the block 8 and matches, and constitutes the rotary stopper structure, and extension one side of screw rod 4 forms external screw thread and matches with a

nut

9 and 8 fix blocking a shot.Handle 1 is provided with slip-resistant texture 16, and following pole 3 lower ends are shaped to anti-skidding cone-shaped 17.

During use, as long as rotate pole 3 down, drive screw rod 4 rotations by the rotary stopper structure, upper and

lower expansion loop

15,13 extruding back notches are outwards opened, and external diameter is the external diameter when static greater than upper and

lower expansion loop

15,13, is close to the inwall of pole 2, produce enough big frictional force, make down pole 3 be fixed on some positions that needs length, produce good fixed effect, reach flexible location purpose; Readjust use length if desired, can be under opposite spin pole 3, upper and

lower expansion loop

15,13 is shunk, adjust length then, just changeing pole 3 down again, retighten.

Because screw rod 4 is provided with spring 5, using at present, pole 3 can stretch automatically, can reduce exercise, improve comfort, because the plastic wrapper 6 of spring 5 overcoats forms the rotary limit device that buckles are connected with block 8, make alpin-stock in use plastic wrapper 6 separate with block 8, can not expand and encircle contraction because of rotation, have only when plastic wrapper 6 and block 8 are in and just can adjust when being connected spacing state, just more safe and reliable when using like this.

The handle 1 of alpin-stock is provided with slip-resistant texture 16, and following pole 3 lower ends are shaped to anti-skidding cone-shaped 17, not only attractive in appearance but also safety.

Embodiment 2

Outer plastic wrapper 6 lower ends of spring 5 are set to flank of tooth structure, and the formation rotary limit device matches with corresponding flank of tooth structure on the block 8.

All the other are with embodiment 1.
